    Background: The main mechanism of fenitrothion (FNT) toxicity is by inhibiting the acetylcholinesterase enzyme, though studies have shown that FNT might also develop other toxicological manifestations, including oxidative stress. However, the kidney functions as well as oxidative stress status after repeated exposure to FNT is not well documented. Objective: The present study was conducted to evaluate the kidney functions and oxidative stress status after exposure to low doses of FNT. Materials and Methods: 24 male Sprague-Dawley rats were divided randomly into three groups (n = 8/group): control, which received 1 mg/ml corn oil; FNT 10, which received 10 mg/kg (BW) FNT; and FNT20 which received 20 mg/kg (BW) FNT. The corn oil and FNT were fed orally for 28 consecutive days. At the end of the study, the blood was taken, and the kidney was obtained for biochemistry evaluation and histological observation. Results: The AChE activity was significantly inhibited in the FNT20 group (p≤0.05) compared to the control group and FNT10 and the rats exhibited the signs and symptoms of toxicity such as lacrimation, piloerection, hypoactivity, and tremor. Plasma creatinine and BUN levels showed a significant increase (p≤0.05) in FNT treated groups, but the superoxide dismutase and glutathione level were significantly reduced (p≤0.05). The malondialdehyde and protein carbonyl level were elevated significantly (p≤0.05) in FNT treated groups. Histopathological observation revealed morphological changes, including atrophy of the glomerulus and presence of non-amyloid substances in FNT treated groups. Conclusion: Even at the dose that did not inhibit the AChE activity, FNT was found to reduce the renal function and induce oxidative damage on the kidney of male Sprague Dawley rats.

    Monosodium glutamate (MSG) is widely used as a food additive but its excessive intake leads to oxidative stress of several organs. However, the oxidative effect of MSG on male accessory reproductive organs remains unclear. Therefore, the aim of this study was to evaluate the effect of MSG on the status of oxidative stress and morphological alterations in the male accessory reproductive organs such as epididymis, prostate glands and seminal vesicle of Sprague-Dawley rats. A total of 24 male Sprague-Dawley rats were randomly divided into three groups with 8 rats per group. Control group received distilled water (1 ml/kg) while MSG60 and MSG120 received 60 mg/kg and 120 mg/kg of MSG, respectively. All the substances were administered via force feed oral for 28 consecutive days. At the end of the study, the rats were sacrificed to obtain the accessory organs for biochemical analysis and histological observations. The SOD activity in the epididymis showed a significant increase in MSG60 and MSG120 compared to control (p < 0.05). The GSH levels in the epididymis of MSG 120 showed a significant reduction (p < 0.05) compared to the control group. The levels of MDA and PC in the epididymis and prostate gland of MSG60 and MSG120 showed a significant increased (p < 0.05) compared to the control group. Histological alterations were found in the epididymis and prostate gland of MSG treated rats. In conclusion, MSG at both doses induced oxidative stress in the epididymis and prostate gland of experimental rats.

    Exposure to organophosphate pesticide including fenitrothion (FNT) has led to many adverse effects on human health.
    However, a potent antioxidant like palm oil tocotrienol-rich fraction (TRF) can reduce oxidative damage in various
    pathological conditions, could also reduce the adverse effects by FNT. The aim of this study was to evaluate the effect
    of TRF on oxidative liver damage in FNT induce hepatotoxicity in experimental rats. A total of 40 male Sprague-Dawley
    rats were randomly divided into four groups of 10, namely control, TRF, FNT and TRF+FNT group. TRF (200 mg/kg
    body weight) and FNT (20 m/kg body weight) were administered through oral gavage for 28 days. Corn oil which
    served as vehicle was given orally to the control group. At the end of the study period, liver and blood was taken for
    oxidative damage and biochemical evaluation and histological observation. TRF supplementation prevents oxidative
    liver damage by reducing the hepatic malondialdehyde (MDA) and protein carbonyl (PCO) level significantly. Besides,
    TRF also restored the endogenous antioxidants particularly reduced glutathione (GSH), glutathione peroxidase (GPx)
    and ferric reducing/antioxidant power (FRAP). TRF also prevent liver damage by reducing the liver enzymes, alanine
    aminotransferase (ALT) and aspartate aminotransferase (AST). The attenuation of liver damage by TRF was also showed
    histologically. In conclusion, TRF supplementation showed a potential in preventing oxidative liver damage in FNTtreated
    rats by reducing the oxidative damage and improving the antioxidant status.

    Penghasilan radikal bebas oleh nikotin dikaitkan dengan kerosakan sistem pembiakan lelaki terutamanya sperma dan testis. Penggunaan rawatan yang berasaskan herba seperti Hibiscus sabdariffa Linn. (HSE) kian meningkat disebabkan kandungan antioksida semula jadi yang tinggi. Oleh itu, kajian ini dijalankan untuk mengkaji kesan ekstrak akueus HSE terhadap kualiti sperma dan tekanan oksidatif testis tikus yang diadministrasi nikotin. Sejumlah 21 ekor tikus jantan Sprague-Dawley dibahagikan secara rawak kepada tiga kumpulan iaitu kumpulan kawalan, nikotin dan nikotin+HSE. Nikotin disuntik secara intraperitoneum pada dos 0.6 mg/kg berat badan manakala HSE diberikan pada dos 100 mg/kg berat badan secara paksaan oral sebelum administrasi nikotin pada setiap hari selama 21 hari berturut-turut. Hasil kajian menunjukkan bilangan, motiliti dan viabiliti sperma lebih tinggi secara signifikan (p<0.05) manakala peratus ketaknormalan morfologi sperma lebih rendah secara signifikan (p<0.05) bagi pada kumpulan nikotin+HSE berbanding kumpulan nikotin. Sementara itu berlakunya penurunan aras malondialdehid (MDA) dan peningkatan aras glutation terturun (GSH) secara signifikan (p<0.05) bagi kumpulan nikotin+HSE berbanding kumpulan nikotin. Pemerhatian histologi mendapati HSE berpotensi melindungi morfologi testis tikus aruhan nikotin. Kesimpulannya, kajian ini menunjukkan bahawa pemberian suplemen ekstrak HSE berpotensi mencegah kerosakan sperma dan testis akibat administrasi nikotin.

    Monosodium glutamate (MSG) is widely used as an additive in food. Excess consumption of MSG was reported to cause oxidative stress on brain, liver and renal resulted in increased production of reactive oxygen species (ROS). This study aims to determine the biochemical and histological effects of low dose MSG on the liver of adult male Sprague-Dawley rats. Animals (n = 6 per group) were randomly divided into three groups with two treatment groups: 60 mg/kg (MSG60) and 120 mg/kg (MSG120), and one control group (distilled water). The substances were administered to the rats via force feeding for 28 consecutive days. On day 29, all rats were killed, and liver tissues were biopsied for the biochemical (total protein, liver enzymes, and the status of oxidative stress) and histological analysis. The total protein appeared significantly decreased (p < 0.05) while alanine aminotransferase (ALT) and aspartate aminotransferase (AST) demonstrated a significant increased (p < 0.05) in the MSG120 treatment group as compared to the control group. Malondialdehyde (MDA) levels and the antioxidant levels of superoxide dismutase (SOD) were significantly increase (p < 0.05) in the MSG120 group as compared to the MSG60 and control groups. The histological findings revealed changes to normal liver architecture and accumulation of red blood cells in the central veins in both MSG groups. This study indicates that the MSG consumption at a dose of 120 mg/kg may ALTer the biochemical and histological parameters of the liver.

    Monosodium glutamate (MSG) is a flavour enhancer commonly used in processed food to increase palatability. Several studies have reported that chronic exposure of MSG causes renal fibrosis via oxidative stress mechanism. However, till date, the effects of low dose of MSG on the oxidative stress status and its histopathological observation of renal are still unclear. A total of 18 male Sprague Dawley rats (170 – 200 g) were divided randomly into three groups consisted of the control (received distilled water = 1 ml/kg), MSG 60 (received 60 mg/kg MSG) and MSG 120 (received 120 mg/kg MSG) groups. All of the substances were given via force-feed oral for 28 consecutive days. At the end of the study, all rats were sacrificed and the renal were isolated for biochemical and histological evaluation. The superoxide dismutase (SOD) activity and protein carbonyl (PC) level showed significantly increased (p < 0.05) in MSG 60 and MSG 120 group compared to the control group. However, no significant difference was found in glutathione (GSH) and malondialdehyde (MDA) level in all treated groups. The histology observation showed glomerulus shrinkage in MSG 60 and MSG 120 groups. In conclusion, these findings confirmed low dose of MSG-induced oxidative stress and histopathological changes on the renal of male Sprague-dawley rats. Accordingly, care must be taken on the intake of MSG in our daily basis.

    The adverse effects of maternal pesticides exposure on the progeny is very well established. However, the impact of paternal exposure to pesticides such as Fenitrothion (FNT) on the histomorphometry of progeny's organs in unexposed mothers are much less well studied. Therefore, this study aims to evaluate the effects of paternal FNT exposure on the sperm quality of the parent rat and its effects on the histomorphometry of the progeny's organs. Randomly, male Sprague Dawley rats (n = 24) categorized as F0 were distributed equally into three groups namely Control, FNT-10, and FNT-20. Control received 1 mL/kg corn oil while FNT-10 and FNT-20 received 10 mg/kg and 20 mg/kg of FNT, respectively, via oral force feeding for 28 consecutive days. At the end of the study, male rats were mated with unexposed female rats and the male rats were sacrificed to obtain sperm for sperm characterization and DNA damage evaluation. Meanwhile, the rats' progeny (F1) namely pControl, pFNT-10, and pFNT-20 were left to grow until postnatal day 70 before being sacrificed to obtain the matured organs for histology and morphometric analysis. Our results showed that both doses of FNT reduced sperm quality and caused DNA fragmentation in F0 rats compared with the control group (p < 0.05). The number of Leydig cells as well as the diameter of the seminiferous tubules and glomerulus of the pFNT-20 group had significantly decreased (p < 0.05) compared with the pControl group. The Bowman's space of the pFNT-20 group had significantly increased (p < 0.05) compared with the pFNT-10 and pControl groups. Therefore, paternal exposure to FNT reduced the sperm quality and increased sperm DNA fragmentation in F0 male Sprague Dawley rats and altered the histology and morphometry of the selected organs in the F1 progeny.

    Previous research reported that prolonged benzene exposure during in utero fetal development causes greater fetal abnormalities than in adult-stage exposure. This phenomenon increases the risk for disease development at the fetal stage, particularly carcinogenesis, which is mainly associated with hematological malignancies. Benzene has been reported to potentially act via multiple modes of action that target the hematopoietic stem cell (HSCs) niche, a complex microenvironment in which HSCs and multilineage hematopoietic stem and progenitor cells (HSPCs) reside. Oxidative stress, chromosomal aberration and epigenetic modification are among the known mechanisms mediating benzene-induced genetic and epigenetic modification in fetal stem cells leading to in utero carcinogenesis. Hence, it is crucial to monitor exposure to carcinogenic benzene via environmental, occupational or lifestyle factors among pregnant women. Benzene is a well-known cause of adult leukemia. However, proof of benzene involvement with childhood leukemia remains scarce despite previously reported research linking incidences of hematological disorders and maternal benzene exposure. Furthermore, accumulating evidence has shown that maternal benzene exposure is able to alter the developmental and functional properties of HSPCs, leading to hematological disorders in fetus and children. Since HSPCs are parental blood cells that regulate hematopoiesis during the fetal and adult stages, benzene exposure that targets HSPCs may induce damage to the population and trigger the development of hematological diseases. Therefore, the mechanism of in utero carcinogenicity by benzene in targeting fetal HSPCs is the primary focus of this review.

    Fenitrothion (FNT) is extensively used as pesticide and may induce oxidative stress in various organs. Tocotrienol, a form of vitamin E found in palm oil, reduces oxidative impairments in pathological conditions. This study aims to investigate the effects of palm oil tocotrienol rich fraction (TRF) on fenitrothion-induced oxidative damage in rat pancreas. Forty male Sprague-Dawley rats were divided into four groups: control group, FNT group, TRF group and FNT+TRF group. Regimens FNT (20 mg kg(-1) b.wt.) and TRF (200 mg kg(-1) b.wt.) were force-fed for 28 consecutive days with control group only receiving corn oil. Chronic administration of fenitrothion significantly (p < 0.05) induced oxidative damage in pancreas of rats with elevated malondialdehyde and protein carbonyl level. Depletion of glutathione and significant (p < 0.05) reduction in antioxidant enzyme activities in pancreas homogenate additionally suggested induction of oxidative stress. Despite these changes in pancreas of intoxicated rats, no significant (p < 0.05) changes in blood glucose and pancreas histology were observed. Co-administration of FNT with TRF alleviated these oxidative changes and significantly (p < 0.05) restored antioxidant status. Enzymatic activities of Superoxide Dismutase (SOD) and Catalase (CAT) were normalized. In conclusion, tocotrienol rich fraction of palm oil prevents fenitrothion-induced pancreatic oxidative damage in rats.

    Oxidative stress involved in various pathological conditions. Plants have been proven to act as a natural exogenous antioxidant. The aim of this research is to investigate the protective effects of Etlingera coccinea leaves aqueous extract on autoxidation-induced ox brain homogenate. The brain homogenate was divided into 7 groups: control group with PBS solution, positive control group with 100 μg/ml ascorbic acid, test group with 25, 50, 100, 200 and 400 μg/ml of E. coccinea. The antioxidant potential of E. coccinea aqueous extract has been evaluated by antioxidant capacity assay such as Total phenolic content (TPC), radical scavenging assay (DPPH) and ferric reducing antioxidant power (FRAP). Malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) were also measured at 0 hr and 1 hr after 37°C water bath incubation to determine the antioxidant status and oxidative damage. TPC assay showed (4.85 ± 0.28) mg GAE/g of dry weight of E. coccinea leaves. Based on DPPH and FRAP assay, E. coccinea aqueous extract showed a dose-dependent antioxidant activity. MDA level in the 50 μg/ml E. coccinea was significantly lower compared to the other groups (p < 0.05). The SOD activity was significantly increase in 400 μg/ml E. coccinea (p < 0.05) compared to other groups. E. coccinea at the dose of 25 μg/ml and 50 μg/ml showed significant increase in GSH level compared to other groups (p < 0.05). In conclusion, 25 μg/ml and 50 μg/ml of E. coccinea leave aqueous extracts exhibited a potential protective effect on autoxidation-induced ox brain homogenate.

    Fenitrothion (FNT) usage has received much attention for its potential to promote free radicals generation and interfere with antioxidant defense system. The aim of the present study was to investigate the effect of palm oil tocotrienol rich fraction (TRF) supplementation on oxidative stress and histological changes in rat brain induced by FNT. A total of 32 male Sprague Dawley rats divided into four groups: control group which received corn oil; TRF group was received palm oil TRF (200 mg/kg bw); FNT group administered with FNT (20 mg/kg bw) and TRF+FNT group pretreated with palm oil TRF (200 mg/kg bw) 30 min prior to administration of FNT (20 mg/kg bw). FNT and TRF were dissolved in corn oil and all supplementations were given by oral gavage once daily for 28 days. After four weeks of supplementation, TRF+FNT rats had significantly lower malondialdehyde (MDA) content and superoxide dismutase (SOD) activity but higher reduced glutathione (GSH) level and total protein level compared to FNT rats (p<0.05). However, protein carbonyl (PC) level was insignificantly lower for TRF+FNT group compared to FNT group. In conclusion, this study suggested that palm oil TRF was effective in preventing brain damage in rats.

    Fenitrothion (FNT) is an organophosphate compound widely used as pesticide in Malaysia. The present study aims to investigate effects of palm oil tocotrienol rich fraction (TRF) on the renal damage of FNT-treated rats. A total of 40 male Sprague Dawley rats were divided into 4 groups randomly, the control, TRF, FNT and FNT+TRF groups. FNT (20 mg/kg b.w.) and TRF (200 mg/kg b.w.) were given orally for 28 days continuously. Rats from the FNT+TRF group were supplemented with TRF 30 minutes prior to administration of FNT. Rats were sacrificed after 28 days, and the kidneys were removed for determination of oxidative stress and histological analysis. Plasma was collected for determination of blood creatinine and urea level. Statistical analysis showed that palm oil TRF has a protective effect against renal oxidative damage induced by FNT. In the FNT+TRF group, malondialdehyde and protein carbonyl levels were significantly lower, while the glutathione level as well as superoxide dismutase and catalase activities were significantly higher compared with the FNT-treated group (p<0.05). As for renal function, there was a markedly lower urea level (p<0.05) in the FNT+TRF group compared with the FNT-treated group, but there was no significant difference in creatinine level. Besides, total protein also showed no significant difference for all groups of rats (p>0.05). Histological evaluation also revealed that the FNT+TRF group had less glomerulus and renal tubule damage than the FNT-treated group. In conclusion, palm oil TRF was able to reduce oxidative stress and renal damage in FNT-treated rats.

    Litsea elliptica Blume has been traditionally used to treat headache, fever, and stomach ulcer, and has also been used as an insect repellent. The acute and subacute toxicities of L. elliptica essential oil were evaluated orally by gavage in female Sprague-Dawley rats. For the acute toxicity study, L. elliptica essential oil was administered in doses from 500 to 4000 mg/kg (single dose), and in the subacute toxicity test, the following doses were used: 125, 250, and 500 mg/kg, for 28 consecutive days. In the acute toxicity study, L. elliptica essential oil caused dose-dependent adverse behaviours and mortality. The median lethal dose value was 3488.86 mg/kg and the acute non-observed-adversed-effect level value was found to be 500 mg/kg. The subacute toxicity study of L. elliptica essential oil did not reveal alterations in body weight, and food and water consumptions. The haematological and biochemical analyses did not show significant differences between control and treated groups in most of the parameters examined, except for the hemoglobin, mean cell hemoglobin concentration, mean cell volume, mean cell hemoglobin, serum albumin, and serum sodium. However, these differences were still within the normal range. No abnormalities or histopathological changes were observed in the liver, pancreatic islet of Langerhans, and renal glomerulous and tubular cells of all treated groups. In conclusion, L. elliptica essential oil can be classified in the U group, which is defined as a group unlikely to present an acute hazard according to World Health Organization (WHO) classification.

    Monosodium glutamate (MSG) is widely used in food preparation industry and has been consumed regularly. Previous studies had reported on effects of MSG when given at extremely high dosages, the results are not applicable to human equivalent intake. Therefore, the present study aimed to evaluate the effect of MSG on sperm quality and changes in reproductive organs of adult male rats when taken at average human daily intake (ADI). Twenty-four adult male rats were randomly assigned into three groups; NC (Normal control), MSG60 and MSG120 where MSG was given orally at 60 mg/kg and 120 mg/kg to each respective group. All treatments were conducted for 28 consecutive days. MSG at estimated ADI of 120 mg/kg body weight resulted in a significant drop in sperm quality (p

    Exposure to organophosphate insecticides such as fenitrothion (FNT) in agriculture and public health has been reported to affect sperm quality. Antioxidants may have a potential to reduce spermatotoxic effects induced by organophosphate. The present study was carried out to evaluate the effects of palm oil tocotrienol-rich fraction (TRF) in reducing the detrimental effects occurring in spermatozoa of FNT-treated rats. Adult male Sprague-Dawley rats were divided into four equal groups: a control group and groups of rats treated orally with palm oil TRF (200 mg/kg), FNT (20 mg/kg) and palm oil TRF (200 mg/kg) combined with FNT (20 mg/kg). The sperm characteristics, DNA damage, superoxide dismutase (SOD) activity, and levels of reduced glutathione (GSH), malondialdehyde (MDA), and protein carbonyl (PC) were evaluated. Supplementation with TRF attenuated the detrimental effects of FNT by significantly increasing the sperm counts, motility, and viability and decreased the abnormal sperm morphology. The SOD activity and GSH level were significantly increased, whereas the MDA and PC levels were significantly decreased in the TRF+FNT group compared with the rats receiving FNT alone. TRF significantly decreased the DNA damage in the sperm of FNT-treated rats. A significant correlation between abnormal sperm morphology and DNA damage was found in all groups. TRF showed the potential to reduce the detrimental effects occurring in spermatozoa of FNT-treated rats.

    Diabetic cardiomyopathy is one of the major mortality risk factors among diabetic patients worldwide. It has been established that most of the cardiac structural and functional alterations in the diabetic cardiomyopathy condition resulted from the hyperglycemia-induced persistent oxidative stress in the heart, resulting in the maladaptive responses of inflammation and apoptosis. Flavonoids, the most abundant phytochemical in plants, have been reported to exhibit diverse therapeutic potential in medicine and other biological activities. Flavonoids have been widely studied for their effects in protecting the heart against diabetes-induced cardiomyopathy. The potential of flavonoids in alleviating diabetic cardiomyopathy is mainly related with their remedial actions as anti-hyperglycemic, antioxidant, anti-inflammatory, and anti-apoptotic agents. In this review, we summarize the latest findings of flavonoid treatments on diabetic cardiomyopathy as well as elucidating the mechanisms involved.

    Indiscriminate application of organophosphate (OP) pesticides has led to environmental pollution and severe health problems. The aim of the present study was to evaluate the effect of palm oil tocotrienol-rich fraction (TRF) on biochemical and morphological changes of the liver in rats treated with fenitrothion (FNT), a type of OP pesticide. A total of 28 male Sprague-Dawley rats were divided into four groups; control group, TRF-supplemented group, FNT-treated group and TRF+FNT group. TRF (200 mg/kg) was supplemented 30 minutes prior to FNT (20 mg/kg) administration, both orally for 28 consecutive days. Following 28 days of treatment, plasma biochemical changes and liver morphology were evaluated. The body and absolute liver weights were significantly elevated in TRF+FNT group compared to FNT group. TRF administration significantly decreased the total protein level and restored the activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in TRF + FNT group. In contrast, total bilirubin level, γ-glutamyltranferase (GGT) and cholinesterase activity in TRF + FNT group did not significantly differ from FNT group. Administration of TRF also prevented FNT-induced morphological changes of liver as observed by electron microscope. In conclusion, TRF supplementation showed potential protective effect towards biochemical and ultrastructural changes in liver induced by FNT.

    Diabetic nephropathy (DN) is known as one of the driving sources of end-stage renal disease (ESRD). DN prevalence continues to increase in every corner of the world andthat has been a major concern to healthcare professionals as DN is the key driver of diabetes mellitus (DM) morbidity and mortality. Hyperglycaemia is closely connected with the production of reactive oxygen species (ROS) that cause oxidative stress response as well as numerous cellular and molecular modifications. Oxidative stress is a significant causative factor to renal damage, as it can activate other immunological pathways, such as inflammatory, fibrosis, and apoptosis pathways. These pathways can lead to cellular impairment and death as well as cellular senescence. Natural substances containing bioactive compounds, such as polyphenols, have been reported to exert valuable effects on various pathological conditions, including DM. The role of polyphenols in alleviating DN conditions has been documented in many studies. In this review, the potential of polyphenols in ameliorating the progression of DN via modulation of oxidative stress, inflammation, fibrosis, and apoptosis, as well as cellular senescence, has been addressed. This information may be used as the strategies for the management of DN and development as nutraceutical products to overcome DN development.

    The cryopreservation of spermatogonia stem cells (SSCs) has been widely used as an alternative treatment for infertility. However, cryopreservation itself induces cryoinjury due to oxidative and osmotic stress, leading to reduction in the survival rate and functionality of SSCs. Glial-derived neurotrophic factor family receptor alpha 1 (GFRα1) and promyelocytic leukemia zinc finger (PLZF) are expressed during the self-renewal and differentiation of SSCs, making them key tools for identifying the functionality of SSCs. To the best of our knowledge, the involvement of GFRα1 and PLZF in determining the functionality of SSCs after cryopreservation with therapeutic intervention is limited. Therefore, the purpose of this review is to determine the role of GFRα1 and PLZF as biomarkers for evaluating the functionality of SSCs in cryopreservation with therapeutic intervention. Therapeutic intervention, such as the use of antioxidants, and enhancement in cryopreservation protocols, such as cell encapsulation, cryoprotectant agents (CPA), and equilibrium of time and temperature increase the expression of GFRα1 and PLZF, resulting in maintaining the functionality of SSCs. In conclusion, GFRα1 and PLZF have the potential as biomarkers in cryopreservation with therapeutic intervention of SSCs to ensure the functionality of the stem cells.

    Hematopoiesis is maintained throughout life from the hematopoietic stem cell niche in which hematopoietic stem cells and lineage-specific hematopoietic progenitors (HSPCs) reside and regulate hematopoiesis. Meanwhile, HSPCs behavior is modulated by both cell intrinsic (e.g., transcriptional factors) and cell extrinsic (e.g., cytokines) factors. Dysregulation of these factors can alter HSPCs function, leading to disrupted hematopoiesis, cellular changes, and subsequent hematological diseases and malignancies. Moreover, it has been reported that chromosomal aberration (CA) in HSPCs following exposure to carcinogenic or genotoxic agents can initiate leukemia stem cells (LSCs) formation which lays a fundamental mechanism in leukemogenesis. Despite reported studies concerning the chromosomal integrity in HSPCs, CA analysis in lineage-specific HSPCs remains scarce. This indicates a need for a laboratory technique that allows the study of CA in specific HSPCs subpopulations comprising differential hematopoietic lineages. Thus, this chapter focuses on the structural (clastogenicity) and numerical (aneugenicity) form of CA analysis in lineage-specific HSPCs comprised of myeloid, erythroid and lymphoid lineages.In this protocol, we describe how to perform CA analysis in lineage-specific HSPCs derived from freshly isolated mouse bone marrow cells (MBMCs) using the combined techniques of colony-forming unit (CFU) and karyotyping. Prior to CA analysis, lineage-specific HSPCs for myeloid, erythroid, and lymphoid were enriched through colony-forming unit (CFU) assay. CFU assay assesses the proliferative ability and differentiation potential of an individual HSPC within a sample. About 6 to 14 days of cultures are required depending on the type of HSPCs lineage. The optimal duration is crucial to achieve sufficient colony growth that is needed for accurate CFU analysis via morphological identification and colony counting. Then, the CA focusing on clastogenicity and aneugenicity anomalies in respective HSPCs lineage for myeloid, erythroid and Pre-B lymphoid were investigated. The resulted karyotypes were classified according to the types of CA known as Robertsonian (Rb) translocation, hyperploidy or complex. We believe our protocol offers a significant contribution to be utilized as a reference method for chromosomal analysis in lineage-specific HSPCs subpopulations.
