Modulation of microRNA-mRNA Target Pairs by Human Papillomavirus 16 Oncoproteins
The E6 and E7 proteins are the major oncogenic drivers encoded by high-risk human papillomaviruses (HPVs). While many aspects of the transforming activities of these proteins have been extensively studied, there are fewer studies that have investigated how HPV E6/E7 expression affects the expression of cellular noncoding RNAs. The goal of our study was to investigate HPV16 E6/E7 modulation of c...
متن کاملSuprabasal expression of the human papillomavirus type 16 oncoproteins in mouse epidermis alters expression of cell cycle regulatory proteins.
Human papillomavirus (HPV) survives by reactivating DNA replication in post-mitotic cells. In the present study, we describe a mouse model of HPV-dependent disease. In these mice, DNA synthesis is activated in suprabasal keratinocytes, leading to acanthosis, parakeratosis and enhanced desquamation. The full-length E6/E7 transcript and two alternately spliced products are produced and in most li...
متن کاملHuman papillomavirus oncoproteins and apoptosis (Review)
The aim of this study was to review the literature and identify the association between human papillomavirus (HPV) oncoproteins and apoptosis. HPV-associated apoptosis may be primarily blocked by a number of oncoproteins, including E5, E6 and E7. E5 protein protects cells from tumor necrosis factor-associated apoptosis; the oncoprotein E6 predominantly inhibits apoptosis through the p53 pathway...
متن کاملCytotoxic T-Cell Markers and Cytokines in Human Papillomavirus 16
Background and Aim: Cervical cancer is the fourth main cause of mortality among women, and annually about half a million new cases are detected in developed countries. Based on oncological studies, human papillomavirus (HPV) is classified into two categories: high-risk type and low-risk type, and most cases are related to the high-risk type of human papillomavirus. HPV 16 and 18 are among the m...
متن کاملThe human papillomavirus type 16 E6 and E7 oncoproteins independently induce numerical and structural chromosome instability.
The development of genomic instability is a hallmark of high-risk human papillomavirus (HPV) associated cervical carcinogenesis. We have previously shown that the HPV-16 E7 oncoprotein rapidly subverts mitotic fidelity by inducing abnormal centrosome numbers and multipolar mitotic spindles. Here we report that expression of HPV-16 E6 and E7 independently results in various mitotic abnormalities...
