PURPOSE About one-third of the world's total annual new cervical cancer cases are found in the People's Republic of China. We investigate the prevalence and clinical characteristics of cervical cancer cases in the People's Republic of China over the past decade. METHOD A total of 10,012 hospitalized patients with cervical cancer from regions nationwide(More)
To identify new genetic risk factors for cervical cancer, we conducted a genome-wide association study in the Han Chinese population. The initial discovery set included 1,364 individuals with cervical cancer (cases) and 3,028 female controls, and we selected a 'stringently matched samples' subset (829 cases and 990 controls) from the discovery set on the(More)
Human papillomavirus (HPV) integration is a key genetic event in cervical carcinogenesis. By conducting whole-genome sequencing and high-throughput viral integration detection, we identified 3,667 HPV integration breakpoints in 26 cervical intraepithelial neoplasias, 104 cervical carcinomas and five cell lines. Beyond recalculating frequencies for the(More)
Vascular endothelial growth factor (VEGF) has been identified to be important in tumor angiogenesis, which is essential for the growth, invasion, and metastasis of solid tumors. The aim of this study was to determine the effect of VEGF overexpression on the invasion of human epithelial ovarian cancer cells in vitro and the possible mechanism involved. The(More)
Several lines of evidence support an important role for Snail, a transcriptional factor, in breast cancer. Overexpression of Snail has been associated with breast cancer metastasis, although the specific role of Snail in the process remains unclear. To address this issue, the expression levels of Snail, RhoA and fibronectin, as well as MMP‑2, were reduced(More)
BACKGROUND AND PURPOSE A number of studies have implicated adipocyte-derived factors in the development of insulin resistance. Intracellular redox status has been reported to play a significant role in the modulation of insulin action. This study was designed to investigate the potential of crocetin, a potent antioxidant, to protect adipocytes against the(More)
Human papillomavirus (HPV) infection is the most important risk factor for the development of cervical cancer. The oncogene E7 from high-risk HPV strains has the ability to immortalize epithelial cells and increase cellular transformation in culture. In this study, we explored the possibility of preventing cervical cancer growth by inhibiting HPV16 E7(More)
AIM To evaluate antitumor activity of sesquiterpene lactones (scabertopin (ES-2), isoscabertopin (ES-3), deoxyelephantopin (ES-4), isodeoxyelephantopin (ES-5)) isolated from Elephantopus scaber L. in vitro and in vivo. METHODS SMMC-7721, Caco-2 and HeLa cell lines were treated with ES-2,3,4,5. Cell viability was determined by MTT assay. Agarose gel(More)
High-risk human papillomavirus (HR-HPV) has been recognized as a major causative agent for cervical cancer. Upon HPV infection, early genes E6 and E7 play important roles in maintaining malignant phenotype of cervical cancer cells. By using clustered regularly interspaced short palindromic repeats- (CRISPR-) associated protein system (CRISPR/Cas system), a(More)
Persistent HPV infection is recognized as the main etiologic factor for cervical cancer. HPV expresses the oncoproteins E6 and E7, both of which play key roles in maintaining viral infection and promoting carcinogenesis. While siRNA-mediated targeting of E6 and E7 transcripts temporarily induces apoptosis in HPV-positive cells, it does not eliminate viral(More)
