Mutations of the human papillomavirus type 16 E7 gene that affect transformation, transactivation and phosphorylation by the E7 protein.
The human papillomavirus type 16 (HPV-16) E7 gene cooperates with an activated ras oncogene to transform primary rodent cells and is important in the immortalization of cervical keratinocytes. We have generated a series of point mutations within the E7 gene and show that mutation of residues serine 31 and serine 71 affect the phosphorylation of the E7 protein, but do not alter its ability to co...
متن کاملDeveloping 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...
متن کاملHuman papillomavirus type 16 E2 and E6/E7 variants.
OBJECTIVES Polymorphisms in human papillomavirus (HPV) type 16 have been shown to be related to geographic areas and are broadly classified as European (E), African (Af), Asian (As), or Asian-American (AA). Certain variants have been reported as being more likely to cause cervical disease; our objectives were to identify new HPV16 polymorphisms, to determine the linkage of the E2 and E6/E7 regi...
متن کاملCTL Responses to a DNA Vaccine Encod-ing E7 Gene of Human Papillomavirus Type 16 from an Iranian Isolate
Background: Cervical cancer is the most prevalent tumor in developing countries and the second most frequent cancer among female population worldwide. Specific human papillomaviruses and, most notably, HPV types 16 and 18 are recognized as being caus-ally associated with cervical carcinomas. The early HPV type 16 genes, E6 and E7, di-rectly participate in the in vitro transformation of primary ...
متن کاملHuman papillomavirus type 16 E7 oncoprotein mediates CCNA1 promoter methylation
Human papillomavirus (HPV) oncoproteins drive distinctive promoter methylation patterns in cancer. However, the underlying mechanism remains to be elucidated. Cyclin A1 (CCNA1) promoter methylation is strongly associated with HPV-associated cancer. CCNA1 methylation is found in HPV-associated cervical cancers, as well as in head and neck squamous cell cancer. Numerous pieces of evidence suggest...
