    Zakaria MN, Jalaei B
    Int J Pediatr Otorhinolaryngol, 2017 Nov;102:28-31.
    PMID: 29106871 DOI: 10.1016/j.ijporl.2017.08.033
    OBJECTIVE: Auditory brainstem responses evoked by complex stimuli such as speech syllables have been studied in normal subjects and subjects with compromised auditory functions. The stability of speech-evoked auditory brainstem response (speech-ABR) when tested over time has been reported but the literature is limited. The present study was carried out to determine the test-retest reliability of speech-ABR in healthy children at a low sensation level.

    METHODS: Seventeen healthy children (6 boys, 11 girls) aged from 5 to 9 years (mean = 6.8 ± 3.3 years) were tested in two sessions separated by a 3-month period. The stimulus used was a 40-ms syllable /da/ presented at 30 dB sensation level.

    RESULTS: As revealed by pair t-test and intra-class correlation (ICC) analyses, peak latencies, peak amplitudes and composite onset measures of speech-ABR were found to be highly replicable. Compared to other parameters, higher ICC values were noted for peak latencies of speech-ABR.

    CONCLUSION: The present study was the first to report the test-retest reliability of speech-ABR recorded at low stimulation levels in healthy children. Due to its good stability, it can be used as an objective indicator for assessing the effectiveness of auditory rehabilitation in hearing-impaired children in future studies.

    Zakaria MA, Abdullah JM, George JP, Mutum SS, Lee NN
    Med J Malaysia, 2006 Jun;61(2):229-32.
    PMID: 16898318 MyJurnal
    Third ventricular cavernous angiomas are rare vascular malformations of the brain. We report an eight-year old boy with a rare third ventricular cavernous angioma that hemorrhaged presenting with symptoms of acute hydrocephalus. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a heterogenous ill-defined, solid and cystic intraventricular mass in the third ventricle which was mildly enhanced with contrast and there was associated hydrocephalus. The mass was removed with success and follow up after two years revealed no neurological abnormalities.

  3. Peri-oral bullous impetigo: a diagnostic dilemma for dentist
    Zakaria A, Sockalingam S
    Sains Malaysiana, 2013;42:89-91.
    Bullous impetigo is a highly contagious skin infection commonly affecting children due to epidermolytic toxins of bacteria Staphylococcus sp. This presentation described a case of a 3 year-old Indian girl with bullous lesion around the peri-oral region. The lesion was initially thought to be of viral origin and was treated symptomatically. However, the lesion progressed without any resolution with more vesicles at distant sites. The patient was also having fever and refused any oral intake. At this point, a probable diagnosis of bacterial skin infection was considered and the patient was admitted. Intra-venous fluid was administered to rehydrate the patient and she was treated with topical antibiotic and antipyretic. The lesion resolved within 14 days without scarring. As dental practitioners, we should be aware of bacterial infection around the peri-oral region and consider it as part of a differential diagnosis so that an appropriate treatment can be given.

  4. Outcome of 2 different types of operative techniques practiced for chronic subdural hematoma in Malaysia: an analysis
    Zakaraia AM, Adnan JS, Haspani MS, Naing NN, Abdullah JM
    Surg Neurol, 2008 Jun;69(6):608-15; discussion 616.
    PMID: 18486703 DOI: 10.1016/j.surneu.2007.01.054
    Traumatic chronic subdural hematomas in Malaysia are increasingly common in young patients after road traffic accidents as well as the elderly who fall at home. Most surgeons in this country manage these pathologies without irrigation, with only a drainage system. This has led to criticism that the recurrence rate might be higher when no irrigation is done and that rates are lower with irrigation and drainage. Thus, a study was done to look into the outcome of TCSH operated with and without irrigation, followed by drainage, to guide the surgeons in Malaysia as to what best could be done for these cases.

  5. Fulltext Chickenpox in pregnancy: still a feared complication
    Zainur Rashid, Z., Sharifah Sulaiha, S.A., Darnina, A.J.
    International Medical Journal Malaysia, 2007;6(2):1-11.
    MyJurnal
    Varicella or chickenpox is an infectious disease caused by Varicella Zoster Virus (VZV), which commonly affects the children. It is a mild, self-limiting disease and rarely complicate to serious conditions except in adults. Decreasing incidence of chickenpox among children, probably owing to improved living conditions ,prevention and health care, is worrisome as growing number of adults are being infected. This creates disturbing concerns in many parties as women at childbearing age might get infected and not only are them at a great risk of serious complications, but also their unborn fetus or their newborn babies.

  6. Fulltext Clinical use of Malay Version of Vertigo Symptom Scale (MWSS) in patients with peripheral vestibular disorder (PVD)
    Zainun Z, Zakaria MN, Sidek D, Ismail Z
    Med J Malaysia, 2012 Aug;67(4):386-9.
    PMID: 23082446
    The Vertigo symptom scale (VSS) is a well established tool for the evaluation of vestibular disorders and the associated symptoms of autonomic arousal and somatosensation. By using a validated Malay version of vertigo symptom scale (MVVSS) questionnaire, the severity of the vertigo from patients' perspective can be determined and rated. Before MVVSS can be applied clinically among Malaysians, it was of interest to determine its clinical value in identifying vestibular disorders.

    Zainum K, Cohen MC
    Forensic Sci Med Pathol, 2017 Jun;13(2):115-122.
    PMID: 28349246 DOI: 10.1007/s12024-017-9860-y
    Suicide is a catastrophic event to both families and communities yet it is potentially preventable. This study aims to determine incidence and patterns of suicide in children and young adolescents in our region, raise awareness of this entity as a potentially preventable cause of death in this age group, and identify its possible associated risk factors. We retrospectively reviewed suicide cases presenting as sudden unexpected death in children and adolescents that underwent coronial post-mortems at our institution. This is the largest pathological review of completed suicide in children and young adolescents within a single institution in the United Kingdom. We identified 23 suicide cases during a 12 year period from 2003 to 2015, in which 18 cases (78%) were male and 5 cases (22%) were female. The age range was from 8 to 16 years (mean age 12.82 +/- 2.52 SD). With the exception of one case, all of the victims were Caucasian. The majority, 19 cases (81%), were found dead inside their place of residence, 15 of whom were discovered in their own bedrooms. Twenty-one cases (91%) died from neck compression due to hanging; 6 cases (26%) had used the cord of a dressing gown and 5 (22%) opted to use a belt as the ligature. Two cases (9%) that died from multiple-drug toxicity were female. In 7 cases (30.5%) there was evidence of self-harm and in 3 cases (13%) there was a history of previous suicide attempts. Petechial hemorrhages were found at autopsy in more than half of hanging victims and only three cases (14%) displayed dual distribution of post-mortem hypostasis (back and legs). Seven victims (30.5%) left some form of suicide message to family members and friends, 2 of which wrote the message on their arm. Parental separation, conflict with parents, and depression, were common amongst decedents prior to committing suicide. Substance abuse was uncommon in suicide within our cases. Valuable information is available from thorough review of suicide data in children and young adolescents from a single institution. Pathologists and clinicians can play crucial roles in identifying potential risk factors that may contribute to prevent future deaths.

    Zainudin NM, Aziz BA, Haifa AL, Deng CT, Omar AH
    Respirology, 2001 Jun;6(2):151-5.
    PMID: 11422895
    OBJECTIVE: Exercise-induced bronchoconstriction (EIB) may be demonstrated in 60-70% of asthmatic children in temperate climates. In areas of high humidity it is postulated to be low. The aim of the study was to determine the prevalence of EIB in a population of schoolchildren with wheezing, living in the humid tropical climate of Kuala Lumpur, Malaysia.

    METHOD: We performed a cross-sectional study using the International Study of Asthma and Allergies in Childhood questionnaire to identify 7-12-year-old Malay children with asthma symptoms from a primary school in central Kuala Lumpur. Sixty-five of 76 children with 'ever wheeze' performed an exercise challenge test successfully in an uncontrolled environment. A random sample of 80 schoolchildren with no history of wheeze were similarly tested as controls. The relative humidity and temperature were recorded. A fall of > 15% was considered as clinically important.

    RESULTS: The prevalence of EIB in schoolchildren with 'ever wheeze' was 47.7%. The prevalence of EIB in children with 'current wheeze' was 51.6%. The prevalence of EIB in controls was 7.5%. The relative humidity during the study ranged from 41 to 90%. There was no significant relationship between different humidity levels and EIB (P = 0.58, regression analysis).

    CONCLUSION: This study demonstrates that EIB is present in asthmatic children despite the highly humid tropical environment.

    Respirology, 1997 Mar;2(1):17-31.
    PMID: 9424402 DOI: 10.1111/j.1440-1843.1997.tb00051.x
    Asthma and chronic obstructive pulmonary disease (COPD) are two common illnesses that cause significant morbidity and mortality. Steroids are widely used in both conditions. They act through steroid or glucocorticoid receptors (GR) causing up or down regulation of protein synthesis resulting in an increase in lipocortin 1 and beta 2 adrenergic receptors, and decreased levels and activities of cytokines or cytokine receptors, which reduces the inflammatory process in the airways and decreases bronchial hyperreactivity. Consequently symptoms of airway obstruction are alleviated and lung function is improved. In asthma, steroids have been convincingly shown to be effective in the treatment of both acute exacerbations and chronic condition. In COPD, however, only a subset of patients seem to respond favourably to steroid therapy. Therapeutic trials are therefore recommended before committing to a long-term treatment in order to determine this subset of patients, as no markers of steroid responsiveness can be identified. The inhaled steroids currently available have a good safety profile with significant side effects occurring only occasionally. Such side effects are usually confined to the oropharynx, causing local irritation, candidiasis and dysphonia, which can be easily overcome. Biochemical abnormalities involving bone, adrenal, carbohydrate and lipid profiles have been noted with high doses of inhaled steroids; however, these have no significant clinical effects.

    Zainudeen ZT, Abd Hamid IJ, Azizuddin MNA, Abu Bakar FF, Sany S, Zolkepli IA, et al.
    BMJ Open, 2021 08 11;11(8):e050523.
    PMID: 34380732 DOI: 10.1136/bmjopen-2021-050523
    OBJECTIVE: To investigate the psychosocial impact of COVID-19 on Malaysian families.

    DESIGN: A cross-sectional study performed using an anonymous online questionnaire distributed through social media, email and the Department of Social Welfare.

    SETTING: Malaysian families were invited to answer the questionnaires. The sampling was performed between 12 May 2020 and 9 June 2020.

    INTERVENTION: The psychological impact was assessed using the Impact of Event Scale-Revised (IES-R) and Children's Revised Impact of Event Scale (CRIES). The mental health status was assessed using the Depression, Anxiety and Stress Scale (DASS) 21.

    MAIN OUTCOME MEASURE: (1) Psychological impact on Malaysian families. (2) Prevalence of mental health status of Malaysian families during COVID-19 pandemic.

    RESULT: A total of 409 Malaysian families have responded (409 parents and 348 children), 154 respondents (38%) reported high psychological impact (score 14) for psychological construct and 189 respondents (46%) reported high psychological impact (score 6) for behavioural construct. A significantly higher proportion of respondents with not permanent employment status of the family lead reported high psychological impact. The prevalence of anxiety reported from family respondents was 23%. Forty-five children answered the DASS-21 questionnaire; 28.5% reported anxiety, 31.4% reported depression and 13.3% reported stress. The job security status of the family lead was found to be the predictive factor for the mean total IES-R score (psychological construct) and ethnicity for mean total CRIES-8 and CRIES-13.

    CONCLUSION: Rates of depression and anxiety during the COVID-19 pandemic were high. Findings suggest that urgent measures to ensure job security among Malaysian families are important to reduce the impact of the COVID-19 pandemic on psychosocial and mental health outcomes.

    PMID: 32580372 DOI: 10.3390/ani10061072
    A better understanding of semen characteristics and resilience to freezing temperatures is necessary before developing assisted reproductive techniques and systematic biobanking for the Sunda clouded leopard. The objective of this study was to evaluate for the first time the semen and sperm quality (in fresh and frozen samples) of two captive Sunda clouded leopards in Malaysia. A total of 17 examinations of the reproductive tract (using ultrasonography) and electro-ejaculations were performed on the two leopards over a 2-year period. Samples obtained from Leopard 1 (8 years old) varied in terms of volume (402 ± 92 µL), pH (7.9 ± 0.9), sperm motility (54.5 ± 24.2%), sperm concentration (122.4 ± 84.7 × 106 sperm/mL), normal morphology (23.9 ± 12.3%), and viability (55.2 ± 18.2%). Midpiece defects represented the most common structural abnormality followed by abnormal tail and head defects. Samples from Leopard 2 (11 year old with abnormal testicular tissue) were of lesser quality. Two frozen semen samples from Leopard 1 were thawed and examined for acrosome integrity. Post-thawed samples contained <10% of motile spermatozoa but almost 50% of abnormal acrosomes. The present results emphasized the high incidence of structurally-abnormal spermatozoa, similar to the mainland clouded leopard. Post-thaw evaluations showed that the few surviving spermatozoa could potentially be used for in vitro fertilization or sperm injection. However, more individuals must be studied to validate those first findings that are exciting but still preliminary.

  12. Malignant glioma: the involvement of loss of allelic heterozygosity and PTEN mutations in a group of Malay patients
    Zainuddin N, Jaafar H, Isa MN, Abdullah JM
    Southeast Asian J. Trop. Med. Public Health, 2005 May;36(3):748-56.
    PMID: 16124450
    Frequent loss of heterozygosity (LOH) and mutations of the tumor suppressor gene PTEN (phosphatase and tensin homologue deleted from chromosome 10) have been found in sporadic gliomas. The most documented regions of allelic losses include 9p21, 10q23-25 and 17p1 3 whereas PTEN aberrations are preferentially found in glioblastoma multiformes. This research aimed to detect the incidence of allelic losses on chromosomes 10q, 9p, 17p and 13q and mutations on exons 5, 6 and 8 of PTEN in malignant gliomas. Malignant glioma specimens obtained were classified histopathologically according to the WHO criteria. Each tumor was then subjected to polymerase chain reaction (PCR)-LOH analysis using microsatellite markers and single-stranded conformational polymorphism (SSCP) analysis. Twelve of 23 (52%) malignant glioma cases showed allelic losses whereas 7 of 23 (30%) samples showed aberrant band patterns and mutations of PTEN. Four of these cases showed LOH in 10q23 and mutations of PTEN. The data on LOH indicated the involvement of different genes in the genesis of glioma whereas mutations of PTEN indicated the role of PTEN tumor suppressor gene in the progression of glioma in Malay population.

    PMID: 14977064
    Recent advances in neuro-oncology have revealed different pathways of molecular oncogenesis in malignant gliomas including loss of heterozygosity on chromosomal regions harboring tumor suppressor genes. In the present study, we performed polymerase chain reaction-loss of heterozygosity (PCR-LOH) analysis using microsatellite markers to identify loss of heterozygosity on chromosomes 10q, 9p, 17p and 13q in the Malays with malignant gliomas. Of 12 cases with allelic losses, seven (58.3%) cases showed LOH on chromosome 10q, three (25.0%) cases showed LOH on chromosome 9p, four (33.3%) cases showed LOH on chromosome 17p and two (16.7%) cases showed LOH on chromosome 13q. The cases include five (41.7%) cases of glioblastoma multiforme, three (25.0%) cases of anaplastic astrocytoma, three (25.0%) cases of anaplastic oligodendroglioma and one (8.3%) case of anaplastic ependymoma. Four cases showed loss of heterozygosity on more than one locus. Our findings showed that loss of heterozygosity on specific chromosomal regions contributes to the molecular pathway of glioma progression in Malay population. In addition, these data provide useful evidence of molecular genetic alterations of malignant glioma in South East Asian patients, particularly in the East Coast of Malaysia.

    PMID: 25070695 DOI: 10.1177/1010539514542422
    The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index-based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes.

    Zainuddin AA, Grover SR, Soon CH, Nur Azurah AG, Mahdy ZA, Wu LL, et al.
    Front Pediatr, 2019;7:144.
    PMID: 31058121 DOI: 10.3389/fped.2019.00144
    Background: Girls born with congenital adrenal hyperplasia have virilized external genitalia. There is considerable debate regarding both the outcomes of feminizing genitoplasty and timing of the surgery in this population. Objective: To investigate outcomes of females 46,XX individuals with CAH in Malaysia, the surgical outcomes of feminizing genitoplasty (FG) and their attitudes toward surgery. Study Design: This is a cross-sectional study involving the two main tertiary centers in Malaysia. All 46,XX patients with CAH and raised female, who had undergone FG were identified and invited to participate. Data on socio-demographic, medical profiles, and attitudes toward surgery were collected. A standardized evaluation of the external genitalia was undertaken including the anatomic and cosmetic evaluation by independent gynecologists. Results: Of 61 individuals identified, 59 participated-consisting of children (n = 12), adolescents (n = 29) and adults (n = 18). All but one had classical CAH (98.3%) and had undergone FG (n = 55, 93.2%) with surgery mostly undertaken by pediatric surgeons trained in DSD work (n = 44, 74.6%). Complications overall were low (20.3%), with repeat surgery rate of 9.1%. External genital examination was performed in 38 participants. Overall 36.8% had absent clitoral glands and 39.5% had a persistent urogenital sinus and in 10.5%, no vaginal orifices were seen. Poor cosmetic outcomes were present in 42.1% with 55.3% recommended for further assessment under general anesthetic. Almost half participants did not venture an opinion on FG, those who did varied from having a positive attitude toward it (18 participants) to 3 opining that it should not be done, or avoided or delayed. From the participants, 35.5% preferred FG to be done early in life compared to 44.0% of the parents. Conclusions: The reoperation rates of the feminizing genitoplasty surgeries were low however due to the anatomic and cosmetic outcomes, reassessment of the external genitalia of these CAH patients may be required once they consider becoming sexually active as they may require further treatment. Many factors such as cultural sensitivities and access to medical treatment and late diagnoses have an impact on attitudes toward FG.

    PMID: 32738912 DOI: 10.1186/s12955-020-01515-9
    BACKGROUND: This study investigates the health-related quality of life (HRQOL) of female patients with congenital adrenal hyperplasia (CAH) in Malaysia. The objectives were to attain socio-demographic and medical data on these Malaysian females with CAH and establish their health-related quality of life (HRQOL) in comparison to age matched diabetic controls.

    METHODS: A cross-sectional study was conducted over 6 months in the two main tertiary centres for CAH patients in Malaysia. Participants including 59 female-raised CAH patients (mean age ± SD = 16.3 ± 4.2 years, range 10-28 years) compared to 57 age-matched female diabetic patients (mean age ± SD = 16.5 ± 3.4 years, range 10-26 years). Socio-demographic and medical profiles was obtained through semi-structured interviews. HRQOL of participants were evaluated utilising validated, Malay translated questionnaires which were age appropriate: Pediatric Quality of Life Inventory (PedsQL v4.0) scales for Child (8-12) and Adolescent (13-18) and Medical Outcome Survey 36-item Short Form version. These were then compared to the diabetic controls.

    RESULTS: The CAH participants consisted of children (ages 10-12 years, n = 12), adolescents (ages 13-17 years, n = 29) and adults (≥ 18 years, n = 18). The majority were Malays (64.4%) and had salt-wasting CAH (67.8%). There were no significant differences between the total mean score of the HRQOL of the combined children and adolescents CAH group (total mean score ± SD = 81.6 ± 17.9, 95% CI = 75.6-87.6) when compared to age-matched diabetic patients (total mean score ± SD = 80.8 ± 11.0, 95% CI = 77.0-84.5, P = 0.81, effect size = 0.05); no significant difference between the adult CAH and diabetic controls in the physical [median score (IQR) CAH vs diabetics; 49.3 (11.4) vs. 50.2 (6.1), P = 0.60, effect size = 0.09] and the mental composite scores [median score (IQR) CAH vs. diabetics; 47.8 (14.1) vs. 50.0 (10.8), P = 0.93, effect size = 0.01].

    CONCLUSIONS: The HRQOL of the Malaysian CAH cohort were comparable to the diabetic controls.

  17. A Multicenter Cross-Sectional Study of Malaysian Females With Congenital Adrenal Hyperplasia: Their Body Image and Their Perspectives on Feminizing Surgery
    Zainuddin AA, Grover SR, Soon CH, Ghani NAA, Mahdy ZA, Manaf MRA, et al.
    J Pediatr Adolesc Gynecol, 2020 Oct;33(5):477-483.
    PMID: 32376362 DOI: 10.1016/j.jpag.2020.04.008
    OBJECTIVE: To explore the impact of congenital adrenal hyperplasia (CAH) on body image in Malaysian females with CAH and to understand the perspectives of these young women and their parents toward feminizing genitoplasty (FG).

    DESIGN: Multi-center cross-sectional study.

    SETTING: Two tertiary medical centers in Malaysia.

    PARTICIPANTS: A total of 59 patients with CAH who were raised as females and more than 10 years old, and their parents.

    METHODS: The CAH respondents completed the validated and translated Body Image Disturbance Questionnaires (BIDQ). All CAH respondents and their parents underwent semi-structured interviews to explore their views on FG.

    MAIN OUTCOME MEASURES: Body image disturbance score and perspectives on FG.

    RESULTS: The 59 CAH respondents consisted of 12 children, 29 adolescents, and 18 adults. The majority were of Malay ethnicity (64.4%) with classical CAH (98.3%) and had undergone FG (n = 55, 93.2%). For the BIDQ scores, the median score (interquartile range) for general body image was 1.29 (0.71), range 1.00-3.29, whereas the genital appearance score was 1.07 (0.39), range 1.00-4.29, revealing a greater concern for general body parts over genitalia. With regards to FG, it was perceived as necessary. Infancy and early childhood were perceived as the best timing for first FG by both respondents and parents, most preferring single-stage over 2-stage surgery.

    CONCLUSIONS: General body appearance concerns were greater than for genital appearance, with more impact on the patients' lives. Contrary to much international opinion, feminizing surgery was perceived as necessary and appropriate by CAH respondents and their families, and should be offered in infancy or early childhood. Future qualitative studies are recommended.

  18. Fulltext Effect of experimental treatment on GAPDH mRNA expression as a housekeeping gene in human diploid fibroblasts
    Zainuddin A, Chua KH, Abdul Rahim N, Makpol S
    BMC Mol. Biol., 2010;11:59.
    PMID: 20707929 DOI: 10.1186/1471-2199-11-59
    Several genes have been used as housekeeping genes and choosing an appropriate reference gene is important for accurate quantitative RNA expression in real time RT-PCR technique. The expression levels of reference genes should remain constant between the cells of different tissues and under different experimental conditions. The purpose of this study was to determine the effect of different experimental treatments on the expression of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA so that the reliability of GAPDH as reference gene for quantitative real time RT-PCR in human diploid fibroblasts (HDFs) can be validated. HDFs in 4 different treatment groups viz; young (passage 4), senescent (passage 30), H2O2-induced oxidative stress and gamma-tocotrienol (GTT)-treated groups were harvested for total RNA extraction. Total RNA concentration and purity were determined prior to GAPDH mRNA quantification. Standard curve of GAPDH expression in serial diluted total RNA, melting curve analysis and agarose gel electrophoresis were used to determine the reliability of GAPDH as reference gene.

    J Physiol Biochem, 2017 Feb;73(1):59-65.
    PMID: 27743340 DOI: 10.1007/s13105-016-0524-2
    Human diploid fibroblasts (HDFs) proliferation in culture has been used as a model of aging at the cellular level. Growth arrest is one of the most important mechanisms responsible for replicative senescence. Recent researches have been focusing on the function of vitamin E in modulating cellular signaling and gene expression. Therefore, the aim of this study was to elucidate the effect of palm γ-tocotrienol (vitamin E) in modulating cellular aging through p16INK4a pathway in HDF cells. Primary culture of senescent HDFs was incubated with 70 μM of palm γ-tocotrienol for 24 hours. Silencing of p16INK4a was carried out by siRNA transfection. RNA was extracted from the different treatment groups and gene expression analysis was carried out by real-time reverse transcription polymerase chain reaction. Proteins that were regulated by p16INK4a were determined by western blot technique.
