Epigenetic repression of E-cadherin by human papillomavirus 16 E7 protein [PDF]

open access: yesCarcinogenesis, 2010
A common feature shared between several human cancer-associated viruses, such as Epstein-Barr virus, Hepatitis B virus and Hepatitis C virus, and Human papillomavirus (HPV) is the ability to reduce the expression of cellular E-cadherin. Since E-cadherin is used by Langerhans cells to move through the stratified epithelium, its reduction may affect the ...

E5 protein of human papillomavirus type 16 selectively downregulates surface HLA class I [PDF]

open access: yes, 2005
Papillomaviruses have evolved mechanisms that result in escape from host immune surveillance. The E5 protein is expressed early in papillomavirus infection in the deep layers of the infected epithelium.

Human Papillomavirus E7 Requires the Protease Calpain to Degrade the Retinoblastoma Protein [PDF]

open access: yesJournal of Biological Chemistry, 2007
Cervical cancers transformed by high risk human papilloma virus (HPV) express the E7 oncoprotein, which accelerates the degradation of the retinoblastoma protein (Rb). Here we show that the E7-mediated degradation of Rb requires the calcium-activated cysteine protease, calpain.

Papillomavirus E5: the smallest oncoprotein with many functions [PDF]

open access: yes, 2011
Papillomaviruses (PVs) are established agents of human and animal cancers. They infect cutaneous and mucous epithelia. High Risk (HR) Human PVs (HPVs) are consistently associated with cancer of the uterine cervix, but are also involved in the ...

A point mutational analysis of human papillomavirus type 16 E7 protein [PDF]

open access: yesJournal of Virology, 1989
The E7 open reading frame of human papillomavirus type 16 (HPV16) has been shown to be selectively retained in cervical tumors and to encode both transforming and trans-activating functions in murine cells, supporting the notion that expression of E7 contributes towards the progression of premalignant cervical lesions.

Papillomavirus E7 protein binding to the retinoblastoma protein is not required for viral induction of warts [PDF]

open access: yesJournal of Virology, 1993
Human papillomaviruses (HPVs) are the etiologic agents responsible for benign epithelial proliferative disorders including genital warts and are a contributory factor in the pathogenesis of cervical cancer. HPVs demonstrate strict species and cell-type specificity, which is manifested by the inability of these viruses to induce disease in any species ...

Downregulation of major histocompatibility complex class I in bovine papillomas [PDF]

open access: yes, 2004
Bovine papillomavirus (BPV) induces papillomas in cattle; in the great majority of cases, these regress due to the host immune response, but they can persist and progress to malignancy.

Interactions with Pocket Proteins Contribute to the Role of Human Papillomavirus Type 16 E7 in the Papillomavirus Life Cycle [PDF]

open access: yesJournal of Virology, 2005
ABSTRACT Human papillomaviruses (HPVs), most commonly the HPV16 genotype, are the principle etiological determinant for cervical cancer, a common cancer worldwide resulting in over 200,000 deaths annually. The oncogenic properties of HPVs are attributable in part to the virally encoded protein E7, best known for its ability to bind to and ...

Equine sarcoids: Bovine Papillomavirus type 1 transformed fibroblasts are sensitive to cisplatin and UVB induced apoptosis and show aberrant expression of p53 [PDF]

open access: yes, 2012
Bovine papillomavirus type 1 infects not only cattle but also equids and is a causative factor in the pathogenesis of commonly occurring equine sarcoid tumours.

Human papillomavirus 16 E7 protein is associated with the nuclear matrix. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1991
The cellular localization of the human papillomavirus (HPV)-16 E7 gene product in the cell lines CaSki and SiHa has been determined by both biochemical and immunocytochemical methods. These measurements show E7 to be localized in the cell nucleus, specifically with the nonchromatin nuclear structure or nuclear matrix.
