OBJECTIVES Although initiated by human papillomavirus (HPV), cervical carcinogenesis demands other cofactors to shape its natural course. Epigenetic effects such as DNA methylation, are considered to contribute to carcinogenesis process. METHODS The methylation status of BLU and RASSF1A, as well as the HPV infection status, were assessed in a full(More)
BACKGROUND DNA methylation may be used a potential biomarker for detecting cervical cancer. The authors of this report used quantitative methylation analysis of 4 genes in a full spectrum of cervical lesions to test its potential clinical application. METHODS This hospital-based, retrospective, case-control study was conducted in 185 patients and included(More)
Testing for DNA methylation has potential in cancer screening. Most previous studies of DNA methylation in cervical cancer used a candidate gene approach. The aim our study was to identify novel genes that are methylated in cervical cancers and to test their potential in clinical applications. We did a differential methylation hybridization using a CpG(More)
OBJECTIVE This study aimed to investigate the status of DNA methylation of 6 genes, LMX1A, NKX6-1, PAX1, PTPRR, SOX1, and ZNF582, previously found from squamous cell carcinomas in adenocarcinomas (ACs) of the uterine cervix. METHODS We assessed the methylation status of these genes in 40 ACs, cervical scrapings from 23 ACs, and 67 normal control cervices(More)
Detection of cervical high-grade squamous intraepithelial lesions (HSIL) in patients with equivocal cytological abnormalities, such as atypical squamous cells (ASC) of undetermined significance (ASCUS) or inability to exclude high-grade squamous intraepithelial lesions (ASC-H) is still a challenge. This study tested the efficacy of PAX1 methylation analysis(More)
BACKGROUND Despite of the trend that the application of DNA methylation as a biomarker for cancer detection is promising, clinically applicable genes are few. Therefore, we looked for novel hypermethylated genes for cervical cancer screening. METHODS AND FINDINGS At the discovery phase, we analyzed the methylation profiles of human cervical carcinomas and(More)
Using DNA methylation biomarkers in cancer detection is a potential direction in clinical testing. Some methylated genes have been proposed for cervical cancer detection; however, more reliable methylation markers are needed. To identify new hypermethylated genes in the discovery phase, we compared the methylome between a pool of DNA from normal cervical(More)
OBJECTIVES DNA methylation has been shown to be a promising cancer biomarker. The aim of this study was to evaluate DNA methylation of three transcription factors, sex-determining region Y-box 1 (SOX1), paired box gene 1 (PAX1), and zinc-finger 582 (ZNF582), in detecting oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS A case-control study was(More)
Women with advanced stage ovarian cancer (OC) have a five-year survival rate of less than 25%. OC progression is associated with accumulation of epigenetic alterations and aberrant DNA methylation in gene promoters acts as an inactivating "hit" during OC initiation and progression. Abnormal DNA methylation in OC has been used to predict disease outcome and(More)
Previously, we showed that progesterone (P4) at physiologic concentrations (5nM-500nM) inhibits proliferation and migration of rat aortic smooth muscle cells (RASMCs). The P4-induced migration inhibition in RASMC was resulted from Rat sacroma homolog gene family, member A (RhoA) inactivation induced by activating the cSrc/AKT/ERK 2/p38 mitogen-activated(More)
