Hepatocellular carcinoma (HCC) is known to be associated with both HBV and HCV. While epigenetic changes have been previously reported to be associated with hepatocellular carcinoma (HCC), whether the epigenetic profile of HBC associated HCC differs from that of HCV-associated HCC is unclear. We analyzed DNA methylation of ten genes (APC, CCND2, CDKN2A,(More)
Previous studies among women worldwide have demonstrated that infection with specific types of human papillomaviruses (HPV) is central to the pathogenesis of cervical neoplasia. There is little data, however, concerning the prevalence of specific HPV types and the association of each type with cervical neoplasia among women in sub-Saharan Africa, who remain(More)
PURPOSE Novel approaches to breast cancer screening are necessary, especially in the developing world where mammography is not feasible. In this study, we explored the hypothesis that blood-based biomarkers have potential for biomarkers for breast cancer. PATIENTS AND METHODS We first determined the frequency of aberrant methylation of four candidate(More)
We used MethyLight assays to analyze DNA methylation status of 27 genes on 49 paired cancerous and noncancerous tissue samples from non-small cell lung cancer (NSCLC) patients who underwent surgical resection. Seven genes (RARB, BVES, CDKN2A, KCNH5, RASSF1, CDH13, and RUNX) were found to be methylated significantly more frequently in tumor tissues than in(More)
OBJECTIVES To measure the risk of preterm delivery, premature rupture of membranes, infant low birth weight and infant mortality, by a population-based retrospective cohort study using Washington State birth certificate data. METHODS All women diagnosed with Chlamydia trachomatis infection (n = 851), noted with a check box on the birth certificate from(More)
OBJECTIVES To assess HIV prevalence and risk factors for HIV infection, to investigate condom use among registered female commercial sex workers (CSWs) in Senegal, West Africa, and to examine the association between previous HIV testing, knowledge of HIV serostatus and condom use with both regular sex partners and clients within this population. METHODS A(More)
BACKGROUND DNA methylation changes are an early event in carcinogenesis and are often present in the precursor lesions of various cancers. We examined whether DNA methylation changes might be used as markers of cervical intraepithelial neoplasia (CIN) and invasive cervical cancer (ICC). METHODS We used methylation-specific polymerase chain reaction (PCR)(More)
BACKGROUND Women infected with human immunodeficiency virus type 1 (HIV-1) and -2 may be at higher risk of developing cervical cancer than uninfected women. We assessed the relationships among human papillomavirus (HPV) types and persistence, HIV-1 and/or HIV-2 infection, and the development of high-grade cervical squamous intraepithelial lesions (HSILs) in(More)
We examined the feasibility of using detection of high-risk human papillomavirus (HPV) DNA in combination with the presence of aberrantly methylated genes (DAPK1, RARB, TWIST1, and CDH13) for urine-based cervical cancer screening. Urine samples from 129 Senegalese women, aged 35 years or older, 110 with (same day) biopsy-proven cervical neoplasia [cervical(More)
A cross-sectional study of 306 women was done to correlate antibody to the chlamydial hsp60 (Chsp60) with epidemiologic, serologic, and laparoscopic findings of women with and without pelvic inflammatory disease (PID). Of the 306 women, 150 had confirmed PID by laparoscopic (n = 69) or histologic (n = 81) criteria, and 156 sexually transmitted disease(More)
