Project description:Cervical cancer is a leading cause of cancer-related death in women worldwide. Nearly all cases of cervical cancer are attributed to infection with human papillomavirus (HPV), mainly high-risk type HPV16 and HPV18. Two viral genes, E6 and E7, play an important role in viral life cycle, since they delay keratinocyte differentiation and stimulate cell cycle progression, allowing the virus to exploit host DNA replication machinery to replicate its genome. Some of the oncogenic properties of E6 and E7 are mediated by host microRNAs (miRNAs) involved in the control of cell proliferation, senescence, and apoptosis. In order to identify genome-wide changes in miRNA expression profile, miRNA microarray analysis was performed on HFKs transduced with retroviral vectors carrying E6 and E7 genes of either HPV6 or HPV16 and with the LXSN empty vector. This dataset was used to identify and to further investigate the role of miR-146a-5p in cervical cancer.

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 type 8 (HPV8) is associated with the development of non-melanoma skin cancer. In the past we already delved into the mechanisms involved in keratinocyte invasion, showing that the viral E7 oncoprotein is a key player that drives invasion of basal keratinocytes controlled by the extracellular protein fibronectin. To unravel further downstream effects in E7 expressing keratinocytes we now characterized alterations of the phospho-proteome in E7 expressing N/TERT keratinocytes.

Project description:The infection with high-risk human papillomavirus is aetiologically linked to cervical cancer, the role of miRNAs regulated by virus oncogene in cancer progression remain largely unknown. Here, we screened the differentially expressed miRNAs with miRNA array between virus oncogene e6/e7 silenced and not in HPV16-positive cervical cancer cell lines In the study, we screened the differentially expressed miRNAs with miRNA array (Exiqon, miRCURY LNA microRNA array, 7th gen [hsa, miRBase 18]) between virus oncogene e6/e7 silenced and not in HPV16-positive cervical cancer cell lines to found miRNAs regulated by virus oncogene e6/e7. Biological replicates: 3 control, 3 e6/e7 silenced, independently grown and harvested. four replicates per array.
