Middle T antigen activation of signal transduction pathways does not overcome p53-mediated growth arrest.

چکیده
Polyomavirus middle T antigen does not overcome p53-mediated G(1) arrest in mouse embryo fibroblasts. Middle T antigen still associates with the signaling molecules phosphatidylinositol 3-kinase and SHC and activates the transcriptional activity of c-Myc and AP1 in p53-arrested cells. Examination of cell cycle regulatory proteins indicated that p53 does not interfere with these mitogenic signals but acts later in the G(1) phase of the cell cycle.

Polyoma virus middle T and small t antigens cooperate to antagonize p53-induced cell cycle arrest and apoptosis.
Wild-type p53 triggers two distinct biological responses, cell cycle arrest and apoptosis. Several small DNA tumor viruses encode proteins that bind p53 and thus block the function of p53. This probably reflects the need of these viruses to prevent p53-induced cell cycle arrest and apoptosis to allow viral DNA replication. Unlike SV40 large T, polyoma virus large T does not bind p53, and it is ...
متن کاملRecent Advances in T Cell Signaling in Aging
The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...
متن کاملp53 amplifies Toll-like receptor 5 response in human primary and cancer cells through interaction with multiple signal transduction pathways
The p53 tumor suppressor regulates transcription of genes associated with diverse cellular functions including apoptosis, growth arrest, DNA repair and differentiation. Recently, we established that p53 can modulate expression of Toll-like receptor (TLR) innate immunity genes but the degree of cross-talk between p53 and TLR pathways remained unclear. Here, using gene expression profiling we cha...
متن کاملInhibition of human p53 basal transcription by down-regulation of protein kinase Cdelta.
In response to DNA damage, signal transduction pathways are activated that result in the increase of p53 protein levels, leading to either growth arrest or apoptosis. Protein kinase C (PKC) delta has been implicated as a tumor suppressor that is down-regulated by tumor-promoting phorbol esters in both mouse skin and cell culture models. We report here that the tumor-promoting phorbol ester 12-O...
متن کاملThe Canonical Wnt Signaling (Wnt/β-Catenin Pathway): A Potential Target for Cancer Prevention and Therapy
Precise regulation of signal transduction pathways is crucial for normal animal development and for maintaining cellular and tissue homeostasis in adults. The Wnt/Frizzled-mediated signaling includes canonical and non-canonical signal transduction pathways. Upregulation or downregulation of the canonical Wnt-signaling (or the Wnt/β-Catenin signal transduction) leads to a variety of human diseas...
