E5 human papillomavirus type 16 oncoprotein modify ST3GAL3 and ST6GAL1 gene expression

Project description:Human papillomavirus (HPV) is the etiological agent of cervical cancer. Three viral proteins, E5, E6 and E7 have been implicated in cell transformation. Increased expression of sialic acid and sialylated antigens have been reported during cervix transformation, these results agree with the increased mRNA levels of the sialyltransferases genes ST6GAL1 and ST3GAL3 reported in premalignant and malignant tissue of the cervix. E6 and E7 HPV oncoproteins modify the expression of some glycogenes. The role of E5 HPV oncoprotein in the glycogene expression changes in premalignant and malignant cervical tissue has not been reported. The objective of this work was to identify glycogenes that modify their expression by E5 HPV oncoprotein in HaCaT cell line. A gene expression microarray was performed on HaCaT cells that stably expressed the HPV16 E5 oncogene. Analysis revealed alteration in some glycogenes including upregulation of ST6GAL1 and ST3GAL3. The increased mRNA levels of both genes were confirmed by qRT-PCR. In addition, an in-silico analysis was performed to identify glycosylation networks altered in presence of E5 oncoprotein. The analysis showed that E5 could modify the sialic acid expression, keratan sulfate synthesis, N-glycosylation and biosynthesis of glycosaminoglycans. This is the first report of the role of HPV16 E5 oncoprotein on glycogenes expression changes. Moreover, our results suggest that the increase of the sialyltransferases genes reported in premalignant and malignant cervical tissue, could be the result of the expression of E5 oncoprotein. These results provide information of the possible role of HPV infection on the sialylation changes in the cervical epithelium identified in premalignant lesions and cancer.

Human Papillomavirus 16 E5 modulates the expression of host microRNAs

Project description:The effect of human papillomavirus 16 E5 oncogene on cellular gene expression in human epithelial cells was studied. Alterations in cellular gene expression due to human papillomavirus type 16 E5 oncogene were studied in triplicate microarray screens. Epithelial cells where E5 expression was induced for 0, 2, 4, 24, 48, 72 and 96h were compared to control cells.

High-risk human papillomavirus E7 affects host keratinocyte DNA methylation

Project description:To investigate the extent of host methylome dysregulation by the human papillomavirus (HPV) oncoprotein E7, we performed methylome array analysis on normal immortalized keratinocytes from skin (NIKS), NIKS cells maintaining the HPV16 or 18 episomes (NIKS-16, NIKS-18, respectively), and NIKS cells maintaining the HPV-16 episome deficient in E7 expression (NIKS-16ΔE7).

High-risk human papillomavirus E7 affects host keratinocyte gene expression

Project description:To investigate the extent of gene expression dysregulation by the human papillomavirus (HPV) oncoprotein E7, we performed global gene expression analysis on normal immortalized keratinocytes from skin (NIKS), NIKS cells maintaining the HPV16 or 18 episomes (NIKS-16, NIKS-18, respectively), and NIKS cells maintaining the HPV-16 episome deficient in E7 expression (NIKS-16ΔE7).

Long non-coding RNA FAM83H-AS1 is regulated by human papillomavirus 16 E6 independently of p53 in cervical cancer cells

Project description:Global long non-coding RNA (lncRNA) expression profile in primary human keratinocytes post-expression of high-risk HPV-16 E6 oncoprotein Purpose: The goal of this study is to utlize high-throughput RNA sequencing (RNA-seq) to identify differentially expressed host lncRNAs with the presence of the high-risk HPV-16 E6 oncoprotein in primary human foreskin keratinocytes. Methods: Primary human foreskin keratinocytes (HEKa) stably expressing HPV-16 E6 compared to GFP control were analyzed, in triplicates, by RNA-seq (Illumina). qRT-PCR validation was performed using SYBR Green assays. Results: 151 up- and 100 down-regulated host lncRNAs were altered greater than 1.5-fold change in HEKa expressing HPV-16 E6 compared to GFP control cells. Altered expression of 16 genes (8 up- and 8 down-regulated) were confirmed by qRT-PCR, demonstrating the high-degree of sensitivity of the RNA-seq method. Conclusions: Our study represents the first global screening of host lncRNAs altered specifically by HPV-16 E6 oncoprotein expression.
