OBJECTIVE To investigate the biological significance of single nucleotide polymorphism (SNP) at Fas gene promoter in cervical carcinogenesis. METHODS SNP at -670 of Fas gene promoter (A/G) together with human papillomavirus (HPV) types were examined in a total of 279 cervical smear samples and 8 human cervical squamous carcinoma cell lines using(More)
Cervical cancer is the most common cancer in Thai women and as yet screening programmes are minimally effective. The Pap smear is the test accepted to be most appropriate for cervical cancer screening so far. One of the main reasons why women do not come to have Pap smear done is "shyness", which weakens compliance with recommendations to undergo Pap smear(More)
Genetic polymorphisms of p53 and its negative regulator murine double minute 2 homolog (MDM2) have been shown to be closely associated with tumorigenesis in a variety of human cancers. In the present study, single nucleotide polymorphism (SNP) at p53 codon 72 and MDM2 promoter 309 was examined for germline DNA samples from 102 endometrial cancer cases and(More)
The clinical significance of glutathione-S-transferase GSTM1, GSTT1 and p53 codon 72 polymorphisms in cervical carcinogenesis was investigated. Germline polymorphisms of GSTM1, GSTT1 and p53 codon 72 together with human papillomavirus (HPV) types were examined in a total of 457 blood and cervical smear samples from normal healthy women and the patients with(More)
The multifactorial process of carcinogenesis involves mutations in oncogenes, or tumor suppressor genes, as well as the influence of environmental etiological factors. Common DNA polymorphisms in low penetrance genes have emerged as genetic factors that seem to modulate an individual’s susceptibility to malignancy. Genetic studies, which lead to a true(More)
OBJECTIVE To investigate the clinical significance of glutathione-S-transferase GSTM1, GSTT1 and p53 codon 72 polymorphisms in cervical carcinogenesis. METHODS GSTM1, GSTT1 and p53 codon 72 polymorphisms together with human papillomavirus (HPV) types were examined in a total of 198 cervical smear samples using multiplex polymerase chain reaction (PCR) and(More)
OBJECTIVE To investigate the biological significance of single nucleotide polymorphism (SNP) at murine double-minute 2 homolog (MDM2) promoter 309 in cervical carcinogenesis. METHODS SNP at MDM2 promoter 309 (T/G) together with human papillomavirus (HPV) types was examined in a total of 195 cervical smear samples and 8 human cervical squamous carcinoma(More)
A functional T to G germline polymorphism in the promoter region of murine double-minute 2 homolog single nucleotide polymorphism 309 (MDM2-SNP309) has been reported to profoundly accelerate tumor formation, suggesting that it may also represent a powerful cancer predisposing allele. In this study, MDM2-SNP309 was examined in a total of 400 blood samples(More)
The aim of the study is to investigate the clinical significance of glutathione-S-transferase GSTM1, GSTT1, and NQO1 c.609C>T (rs1800566) genetic polymorphisms in cervical carcinogenesis. GSTM1, GSTT1, and NQO1 polymorphisms together with human papillomavirus (HPV) types were examined in a total of 192 cervical smear in exfoliated cervical cell samples(More)
Genes of the RAF family, which mediate cellular responses to growth signals, encode kinases that are regulated by RAS and participate in the RAS, RAF, mitogen/extracellular signal-regulated kinase, extracellular signal-regulated kinase and mitogen-activated protein kinase pathway. As BRAF is a serine/threonine kinase that is commonly activated by somatic(More)
