  1. Role of fish oil in human health and possible mechanism to reduce the inflammation
    Ellulu MS, Khaza'ai H, Abed Y, Rahmat A, Ismail P, Ranneh Y
    Inflammopharmacology, 2015 Jun;23(2-3):79-89.
    PMID: 25676565 DOI: 10.1007/s10787-015-0228-1
    The roles of Omega-3 FAs are inflammation antagonists, while Omega-6 FAs are precursors for inflammation. The plant form of Omega-3 FAs is the short-chain α-linolenic acid, and the marine forms are the long-chain fatty acids: docosahexaenoic acid and eicosapentaenoic acid. Omega-3 FAs have unlimited usages, and they are considered as omnipotent since they may benefit heart health, improve brain function, reduce cancer risks and improve people's moods. Omega-3 FAs also have several important biological effects on a range of cellular functions that may decrease the onset of heart diseases and reduce mortality among patients with coronary heart disease, possibly by stabilizing the heart's rhythm and by reducing blood clotting. Some review studies have described the beneficial roles of Omega-3 FAs in cardiovascular diseases (CVDs), cancer, diabetes, and other conditions, including inflammation. Studies of the effect of Omega-3 FAs gathered from studies in diseased and healthy population. CVDs including atherosclerosis, coronary heart diseases, hypertension, and metabolic syndrome were the major fields of investigation. In studies of obesity, as the central obesity increased, the level of adipocyte synthesis of pro-inflammatory cytokines like tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) were increased and the level of anti-inflammatory adiponectin was decreased indicating a state of inflammation. The level of C reactive protein (CRP) synthesized from hepatocyte is increased by the influence of IL-6. CRP can be considered as a marker of systemic inflammation associated with increased risks of CVDs. In molecular studies, Omega-3 FAs have direct effects on reducing the inflammatory state by reducing IL-6, TNF-α, CRP and many other factors. While the appropriate dosage along with the administrative duration is not known, the scientific evidence-based recommendations for daily intake are not modified.

    PMID: 26320494
    BACKGROUND: Hepatocellular carcinoma is one of the most common cancers worldwide. Its prevalence is increasing in many countries. Plant products can be used to protect against cancer due to natural anticancer and chemopreventive constituents. Strobilanthes crispus is one of plants with potential chemopreventive ability.

    OBJECTIVE: This study aimed to evaluate the anticancer effects of Strobilanthes crispus juice on hepatocellular carcinoma cells.

    MATERIALS AND METHODS: MTT assays, flow cytometry, comet assays and the reverse transcription- polymerase chain reaction (RT-PCR) were used to determine the effects of juice on DNA damage and cancer cell numbers.

    RESULTS: This juice induced apoptosis after exposure of the HepG2 cell line for 72 h. High percentages of apoptotic cell death and DNA damage were seen at the juice concentrations above 0.1%. It was found that the juice was not toxic for normal cells. In addition, juice exposure increased the expression level of c-myc gene and reduced the expression level of c-fos and c-erbB2 genes in HepG2 cells. The cytotoxic effects of juice on abnormal cells were in dose dependent.

    CONCLUSIONS: It was concluded that the Strobilanthes crispus juice may have chemopreventive effects on hepatocellular carcinoma cells.

    Abu Bakar MF, Ahmad NE, Suleiman M, Rahmat A, Isha A
    Biomed Res Int, 2015;2015:916902.
    PMID: 26557713 DOI: 10.1155/2015/916902
    Garcinia dulcis or locally known in Malaysia as "mundu" belongs to the family of Clusiaceae. The study was conducted to investigate the anticancer potential of different parts of G. dulcis fruit extracts and their possible mechanism of action in HepG2 liver cancer cell line. MTT assay showed that the peel, flesh, and seed extracts of G. dulcis induced cytotoxicity in HepG2 cell line with IC50 values of 46.33 ± 4.51, 38.33 ± 3.51, and 7.5 ± 2.52 µg/mL, respectively. The flesh extract of G. dulcis induced cell cycle arrest at sub-G1 (apoptosis) phase in a time-dependent manner. Staining with Annexin V-FITC and propidium iodide showed that 41.2% of the cell population underwent apoptosis after 72 hours of exposure of the HepG2 cell line to G. dulcis flesh extract. Caspase-3 has been shown to be activated which finally leads to the death of HepG2 cell (apoptosis). GC-MS analysis showed that the highest percentage of compound identified in the extract of G. dulcis flesh was hydroxymethylfurfural and 3-methyl-2,5-furandione, together with xanthones and flavonoids (based on literature), could synergistically contribute to the observed effects. This finding suggested that the flesh extract of G. dulcis has its own potential as cancer chemotherapeutic agent against liver cancer cell.

    Abu Bakar MF, Abdul Karim F, Suleiman M, Isha A, Rahmat A
    Evid Based Complement Alternat Med, 2015;2015:936215.
    PMID: 26640502 DOI: 10.1155/2015/936215
    The study aimed to investigate the phytochemical contents, antioxidant and antiproliferative activity of 80% methanol extract of Lepidozia borneensis. The total phenolic and total flavonoid contents were analysed using Folin-Ciocalteu and aluminium chloride colorimetric methods. Antioxidant properties were evaluated by using FRAP, ABTS, and DPPH assays while the effects of L. borneensis on the proliferation of MCF-7 cell line were evaluated by using MTT assay. The results showed that the total phenolic and flavonoid contents were 12.42 ± 0.47 mg GAE/g and 9.36 ± 1.29 mg CE/g, respectively. The GC-MS analysis revealed the presence of at least 35 compounds. The extract was found to induce cytotoxicity against MCF-7 cell line with IC50 value of 47.33 ± 7.37 µg/mL. Cell cycle analysis showed that the extract induced significant arrest at G0/G1 at 24 hours of treatment. After 72 hours of treatment, the proportion of cells in G0/G1 and G2-M phases had decreased significantly as compared to their control. Apoptosis occurred during the first 24 hours and significantly increased to 30.8% after 72 hours of treatment. No activation of caspase 3 was observed. These findings suggest that L. borneensis extract has the potential as natural antioxidant and anticancer agents.

    PMID: 26171246 DOI: 10.1155/2015/846041
    This study aims to investigate the protective effect of Cyphomandra betacea in adult male Sprague-Dawley rats fed with high fat diet. Rats were fed on either normal chow or high fat diet for 10 weeks for obesity induction phase and subsequently received C. betacea extract at low dose (150 mg kg(-1)), medium dose (200 mg kg(-1)), or high dose (300 mg kg(-1)) or placebo via oral gavages for another 7 weeks for treatment phase. Treatment of obese rats with C. betacea extracts led to a significant decrease in total cholesterol and significant increase in HDL-C (p < 0.05). Also there was a trend of positive reduction in blood glucose, triglyceride, and LDL-C with positive reduction of body weight detected in medium and high dosage of C. betacea extract. Interestingly, C. betacea treated rats showed positive improvement of superoxide dismutase (SOD) activity and glutathione peroxidase (GPx) activity along with a significant increase of total antioxidant status (TAS) (p < 0.05). Further, rats treated with C. betacea show significantly lower in TNF-α and IL-6 activities (p < 0.05). This study demonstrates the potential use of Cyphomandra betacea extract for weight maintenance and complimentary therapy to suppress some obesity complication signs.

    Eur J Pharmacol, 2014 Oct 5;740:584-95.
    PMID: 24973693 DOI: 10.1016/j.ejphar.2014.06.025
    Breast cancer is the most common cancer among women worldwide and novel therapeutic agents are needed to treat this disease. The plant-based alkaloid berberine has potential therapeutic applications for breast cancer, although a better understanding of the genes and cellular pathways regulated by this compound is needed to define the mechanism of its action in cancer treatment. In this review, the molecular targets of berberine in various cancers, particularly breast cancer, are discussed. Berberine was shown to be effective in inhibiting cell proliferation and promoting apoptosis in various cancerous cells. Some signaling pathways affected by berberine, including the MAP (mitogen-activated protein) kinase and Wnt/β-catenin pathways, are critical for reducing cellular migration and sensitivity to various growth factors. This review will discuss recent studies and consider the application of new prospective approaches based on microRNAs and other crucial regulators for use in future studies to define the action of berberine in cancer. The effects of berberine on cancer cell survival and proliferation are also outlined.

    PMID: 24444147 DOI: 10.1186/1472-6882-14-32
    BACKGROUND: This paper is to investigate the effects of Centella asiatica on HepG2 (human hepatocellular liver carcinoma cell line). Centella asiatica is native to the Southeast Asia that is used as a traditional medicine. This study aims to determine the chemopreventive effects of the Centella asiatica juice on human HepG2 cell line.

    METHODS: Different methods including flow cytometry, comet assay and reverse transcription-polymerase chain reaction (RT-PCR) were used to show the effects of juice exposure on the level of DNA damage and the reduction of cancerous cells. MTT assay is a colorimetric method applied to measure the toxic effects of juice on cells.

    RESULTS: The Centella asiatica juice was not toxic to normal cells. It showed cytotoxic effects on tumor cells in a dose dependent manner. Apoptosis in cells was started after being exposed for 72 hr of dose dependent. It was found that the higher percentage of apoptotic cell death and DNA damage was at the concentration above 0.1%. In addition, the juice exposure caused the reduction of c-myc gene expression and the enhancement of c-fos and c-erbB2 gene expressions in tumor cells.

    CONCLUSIONS: It was concluded that the Centella asiatica juice reduced liver tumor cells. Thus, it has the potential to be used as a chemopreventive agent to prevent and treat liver cancer.

    ScientificWorldJournal, 2014;2014:964731.
    PMID: 25379555 DOI: 10.1155/2014/964731
    The aim of this study was to examine the effects of extraction methods on antioxidant capacities of red dragon fruit peel and flesh. Antioxidant capacities were measured using ethylenebenzothiozoline-6-sulfonic acid (ABTS) radical cation assay and ferric reducing antioxidant power assay (FRAP). Total phenolic content (TPC) was determined using Folin-Ciocalteu reagent while quantitative determination of total flavonoid content (TFC) was conducted using aluminium trichloride colorimetric method. Betacyanin content (BC) was measured by spectrophotometer. Red dragon fruit was extracted using conventional (CV) and ultrasonic-assisted extraction (UE) technique to determine the most efficient way of extracting its antioxidant components. Results indicated that UE increased TFC, reduced the extraction yield, BC, and TPC, but exhibited the strongest scavenging activity for the peel of red dragon fruit. In contrast, UE reduced BC, TFC, and scavenging activity but increased the yield for the flesh. Nonetheless, UE slightly increases TPC in flesh. Scavenging activity and reducing power were highly correlated with phenolic and flavonoid compounds. Conversely, the scavenging activity and reducing power were weakly correlated with betacyanin content. This work gives scientific evidences for the consideration of the type of extraction techniques for the peel and flesh of red dragon fruit in applied research and food industry.

    Type 2 diabetes is a chronic disease with growing public health concern globally. Finding remedies to assist this health issue requires recruiting appropriate animal model for experimental studies. This study was designated to evaluate metabolic and immunologic changes in streptozotocin-nicotinamide induced diabetic rats as a model of type 2 diabetes. Male rats were induced diabetes using nicotinamide (110 mg/kg) and streptozotocin (65 mg/kg). Following 42 days, biochemical and immunological tests showed that diabetic rats had higher levels of blood glucose, WBC, certain abnormalities in lipid profile and insufficient mitogenic responses of lymphocytes (p<0.05). However, the status of the total antioxidant, inflammatory biomarkers and other parameters of full blood count (except HCT) were not significantly altered. Phenotyping assay indicated insignificant lymphocyte subtype imbalances excluding a significant rise in the level of CD4+CD25+ marker (p<0.05). This model of diabetic animals may represent some but not all symptoms of human type 2 diabetes.

    In current work, the nutritional composition, bioactive compounds, total phenolic contents and anti-oxidant activity of young Malaysian ginger rhizome were investigated. Proximate analysis and high performance liquid chromatography (HPLC) recruited to determine nutritional composition and bioactive compounds. The total flavonoid (TF) and total phenolic contents (TPC) of ginger rhizome were determined by aluminium chloride calorimetric assay and Folin-Ciocalteau reagent, respectively. 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method were used to measure antioxidant capacity. The rhizome contained high moisture content and low level of carbohydrate and energy. 6-gingerol was the most abundant component in the selected ginger, and total flavonoid and phenolic content were reported to be 3.66±0.45 mg gallic acid/g and 10.22±0.87 mg quercetin/g of dry weight of rhizome, respectively. The rhizome also showed lower antioxidant activity than controls, with the IC 50 value of 46.5 vs. 15.5 for α-tocopherol and 22 for BHT. The results of this study predicted that the young ginger rhizome originated from Malaysia may exhibit anti-oxidative and anti-inflammatory potentials due to high levels of gingerols, total flavonoid and phenolic compounds and antioxidant capacity.

    PMID: 28962304 DOI: 10.1016/j.toxrep.2014.10.022
    Oxidative stress attributes a crucial role in chronic complication of diabetes. The aim of this study was to determine the most effective part of pomegranate on oxidative stress markers and antioxidant enzyme activities against streptozotocin-nicotinamide (STZ-NA)-induced diabetic rats. Male Sprague-Dawley rats were randomly divided into six groups. Experimental diabetes was induced by a single intraperitoneal injection (i.p), 15 min after the i.p administration of NA. Diabetic rats showed significant increase in plasma glucose level, and the significant decrease in plasma insulin level. The activities of antioxidant enzymes such as total antioxidant status (TAS), superoxide dismutase (SOD), and catalase (CAT) reduced while the levels of biomarkers of oxidative stress such as gamma-glutamyle transferase (GGT), and malondialdehyde (MDA) increased in diabetic control rats as compared to normal control rats. Oral treatment with pomegranate seed-juice for 21 days demonstrated significant protective effects on all the biochemical parameters studied. Besides, biochemical findings were supported by histopathological study. These results revealed that pomegranate has potential protective effect against oxidative stress induced diabetic rats.

    PMID: 24693327 DOI: 10.1155/2014/873803
    In this study, we investigated some bioactive compounds and pharmaceutical qualities of curry leaf (Murraya koenigii L.) extracts from three different locations in Malaysia. The highest TF and total phenolic (TP) contents were observed in the extracts from Kelantan (3.771 and 14.371 mg/g DW), followed by Selangor (3.146 and 12.272 mg/g DW) and Johor (2.801 and 12.02 mg/g DW), respectively. High quercetin (0.350 mg/g DW), catechin (0.325 mg/g DW), epicatechin (0.678 mg/g DW), naringin (0.203 mg/g DW), and myricetin (0.703 mg/g DW) levels were observed in the extracts from Kelantan, while the highest rutin content (0.082 mg/g DW) was detected in the leaves from Selangor. The curry leaf extract from Kelantan exhibited higher concentration of gallic acid (0.933 mg/g DW) than that from Selangor (0.904 mg/g DW) and Johor (0.813 mg/g DW). Among the studied samples, the ones from Kelantan exhibited the highest radical scavenging activity (DPPH, 66.41%) and ferric reduction activity potential (FRAP, 644.25  μ m of Fe(II)/g) followed by those from Selangor (60.237% and 598.37  μ m of Fe(II)/g) and Johor (50.76% and 563.42  μ m of Fe(II)/g), respectively. A preliminary screening showed that the curry leaf extracts from all the locations exhibited significant anticarcinogenic effects inhibiting the growth of breast cancer cell line (MDA-MB-231) and maximum inhibition of MDA-MB-231 cell was observed with the curry leaf extract from Kelantan. Based on these results, it is concluded that Malaysian curry leaf collected from the North (Kelantan) might be potential source of potent natural antioxidant and beneficial chemopreventive agents.

    Carbohydr Polym, 2013 Nov 6;98(2):1281-7.
    PMID: 24053804 DOI: 10.1016/j.carbpol.2013.07.069
    In this study, the interactions of α-tocopherol (α-TOH) in PVOH-starch blends were investigated. α-TOH is an interacting agent possesses a unique molecule of polar chroman "head" and non-polar phytyl "tail" which can improve surface interaction of PVOH and starch. It showed favorable results when blending PVOH-starch with α-TOH, where the highest tensile strengths were achieved at 60 wt.% PVOH-starch blend for 1 phr α-TOH and 50 wt.% for 3 phr α-TOH, respectively. This due to the formation of miscible PVOH-starch as resulted by the compatibilizing effect of α-TOH. Moreover, the enthalpy of melting (ΔHm) of 60 wt.% PVOH-starch and 50 wt.% PVOH-starch added with 1 and 3 phr α-TOH respectively were higher than ΔHm of the neat PVOH-starch blends. The thermogravimetry analysis also showed that α-TOH can be used as thermal stabilizer to reduce weight losses at elevated temperature. The surface morphologies of the compatible blends formed large portion of continuous phase where the starch granules interacted well with α-TOH by acting as compatilizer to reduce surface energy of starch for embedment into PVOH matrix.

    Pak J Biol Sci, 2013 Oct 15;16(20):1104-12.
    PMID: 24506009
    This study was aimed to investigate the production of methane gas from three different types of food waste (vegetables waste, fruit waste and grain waste) using batch type anaerobic digestion method. The digestion process was conducted by using temperature range of 27 to 36 degrees C and pH 6.5 to 7.5 to yield an optimum condition for the digestion process. The digestion was continued for a period of two weeks with the aid of cow dung as the inoculums. It was found that the grain waste yielded the highest methane 2546 mL due to the high content of carbohydrate. At the mean time, the fruit waste produced the second highest methane gas with 2000 mL as well as the vegetable waste generated the lowest methane gas with volume of 1468 mL. The vegetable waste produced the lowest methane gas because the vegetables waste contains high fibres and cellulose walls but low in glucose amount. For the fertilization test, fruit waste demonstrated the best observation for the growth of plant due to high content of potassium and followed by vegetable waste. The least effective fertilizer was grain waste due to less content of nutrients essential for plants growth.
