Project description:The Illumina 850k Human DNA methylation EPIC BeadChip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in the formalin-fixed and paraffin-embedded tissue sections(FFPE). Samples included 3 normal samples without HPV and 6 cervical cancer samples (three HPV 16 positive,three HPV 18 positive).

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.

Project description:Human papillomavirus (HPV) infection related malignancy remains a severe public health problem worldwide, although HPV prophylactic vaccine has been introduced 15 years ago . HPV-associated cancers comprise 29.1% of all 2.2 million infection-related cancers, including nearly 100% of cervical cancers1 and some head and neck cancers . Cervical cancers are the 3rd most common cancer in women worldwide, HPV16 and 18 account for about 70% of cervical cancers. Moreover, high-risk HPV infection, especially HPV16 infection, is related to a proportion of head and neck epithelial carcinoma in both developed and undeveloped countries. HPV related cancers are most severe in developing countries where HPV prophylactic vaccination rates are low.In this project, we use iTRAQ8plex-labelling proteomics to comparatively study the protein contents in the tumour tissues of early and late stage cervical cancer patietns.

Project description:The study examined the infection state of HPV in the Uyghur population with cervical cancer, followed by genotyping to determine the variation in the types of HPV. Using microRNA microarray technology, differential gene expression between HPV-infected cervical cancer and uninfected normal cervical tissues was determined. The microarray results were verified by qRT-PCR using 20 sets of HPV-infected cervical cancer and uninfected cervical tissues.

Project description:The aim of this study was to identify new candidate genes that are differentially methylated in squamous cell carcinoma compared to the DNA samples from cervical intraepithelial neoplasia grade 3 (CIN3) and normal cervical scrapes. The Illumina Infinium Human Methylation 450 K BeadChip method identifies genome-wide DNA methylation changes in CpG islands, CpG shores and shelves. In this study 20 normal cervical samples (HPV negative), 18 samples with CIN3 lesions (HPV positive) and 6 cervical cancer tissues (HPV positive) were included.

Project description:Although Human papillomavirus infection is the main causal factor for cervical cancer (CC), there is data suggesting genetic factors could modulate the risk and progression of CC. Sibling studies suggest that maternally inherited factors could be involved in CC. To assess whether mitochondrial DNA (mtDNA) polymorphisms are associated to cervical cancer, HPV infection and HPV types, a case-control study was performed in the Mexican mestizo population. The polymorphism of mtDNA D-Loop was investigated in 187 cervical cancer patients and 270 healthy controls. D-loop was amplified from a blood DNA sample and analyzed by sequencing. HPV was detected and typed in cervical scrapes from both groups. mtDNA polymorphisms were compared in the whole samples and stratified by HPV types. The expression of 29 mitochondrial genes was analyzed in a subset of 45 tumor biopsies using the expression microarray ST1.0. The Amerindian haplogroup B2 increased the risk for CC (OR=1.6, 95% CI: 1.05-2.58) and showed an additive effect of 36% over the risk conferred by the HPV (OR=153, 95% CI: 65.4-357.5). The frequency of HPV 16, 18, 31 and 45 in cancer samples was similar in all haplogroups but one (D1). It showed a very low frequency of HPV16, any HPV18 and high frequency of HPVs 31, 45 and other types. Two mtDNA genes (MT-TD, MTTK) could be involved in the increased risk conferred by the haplogroup B2, since they were up-regulated exclusively in B2 tumors (p<0.05, t-test). These findings will contribute to clarify the importance of genetic factors in CC.

Project description:The human papillomavirus virus (HPV) is a proven cause of most human cervical cancers, and might have a role in other malignancies including vulva, skin, oesophagus, head and neck cancer. HPV has also been speculated to have a role in the pathogenesis of lung cancer. To validate the hypothesis of HPV involvement in small cell lung cancer pathogenesis we performed gene expression profile of transgenic mouse model of SCLC induced by HPV-16 E6/E7 oncoproteins.
