Large T and small T antigens of Merkel cell polyomavirus.
Merkel cell polyomavirus (MCV) is the etiological agent of Merkel cell carcinoma (MCC), a rare and highly lethal human skin cancer. A natural component of skin flora, MCV becomes tumorigenic only after integration into the host DNA together with specific mutations to the viral genome. Research on MCV large T (LT) and small T (sT) antigens, the only viral products expressed in MCC, shows that th...
متن کاملExtraction and fingerprint analysis of simian virus 40 large and small T-antigens.
A study of simian virus 40 (SV40) T-antigens isolated from productively infected CV1 cells using a variety of different extraction procedures showed that under some conditions the highest molecular weight form of T-Ag (large-T) isolated comigrated on sodium dodecyl sulfate-polyacrylamide gel electrophoresis with large-T from SV40-transformed H65-90B cells. Other faster-migrating forms of large-...
متن کاملBK virus large T and VP-1 expression in infected human renal allografts
OBJECTIVE We investigated the expression of early and late phase BK virus (BKV) proteins and their interactions with host cell proteins in renal allografts, with ongoing polyomavirus associated nephropathy (PVAN), and correlated this with the nuclear and cell morphology. METHODS Frozen sections from three patients with renal allografts (two biopsies, one explant) with PVAN were analysed by in...
متن کاملThe amino-terminal transforming region of simian virus 40 large T and small t antigens functions as a J domain.
Simian virus 40 (SV40) encodes two proteins, large T antigen and small t antigen that contribute to virus-induced tumorigenesis. Both proteins act by targeting key cellular regulatory proteins and altering their function. Known targets of the 708-amino-acid large T antigen include the three members of the retinoblastoma protein family (pRb, p107, and p130), members of the CBP family of transcri...
متن کاملThe Expression of T-Helper Associated Transcription Factors and Cytokine Genes in Pre-Eclampsia
Background: Pre-eclampsia (PE) is known as a main factor contributing to fetomaternal mortality, which might affect 2-8% of all pregnancies after the twentieth week of gestation. The balance of T helper subsets is essential to sustain a normal pregnancy and preventing fetomaternal complications. Objective: To investigate differences in the levels of transcription factors and cytokine gene e...
