E6/E7 Oncogenes Mutation of Human Papillomavirus Type 16 Associated with P16 Protein Expression in Cervical Cancer

Developing Michigan Cancer Foundation 7 Cells with Stable Expression of E7 Gene of Human Papillomavirus Type 16

Background: Human papillomavirus (HPV) is responsible for the development of cervical neoplasia.  Infection with human papillomavirus type 16 (HPV-16) is a major risk factor for the development of cervical cancer. The virus encodes three oncoproteins (E5, E6 and E7), of which, the E7 oncoprotein is the major protein involved in cell immortalization and transformation o...

Integration of human papillomavirus type 16 in cervical cancer cells

Cervical cancer remains an important cause of women morbidity and mortality. The progression of cervical pathology correlates with the HPV integration into the host genome. However, the data on the viral integration status in cervical dysplasias are controversial. The aim of the current study was to evaluate the status of HPV integration in two types of cervical pathology - invasive and non inv...

Papillomavirus Type 16 by the Cervical Cancer - Associated Human TLR 9 Expression and Function Is Abolished

TLR9 expression and function is abolished by the cervical cancer-associated human papillomavirus type 16.

Cervical cancer development is linked to the persistent infection by high-risk mucosal human papillomaviruses (HPVs) types. The E6 and E7 major oncoproteins from this dsDNA virus play a key role in the deregulation of the cell cycle, apoptosis, and adaptive immune surveillance. In this study, we show for the first time that HPV type 16 (HPV16), the most carcinogenic type among the high-risk sub...

Human papillomavirus type 16 variants and risk of cervical cancer.

There are substantial data demonstrating that human papillomaviruses (HPVs) are the sexually transmitted etiologic agents of cervical cancer (1). HPV type 16 (HPV16) is the most common HPV type detected in tumors, accounting for 50% of cancers and their precursors, called high-grade squamous intraepithelial lesions (HSILs) (2). Preliminary studies (3–16) have suggested that variants of HPV16 ma...
