Wild-type p53 enhances efficiency of simian virus 40 large-T-antigen-induced cellular transformation

ABSTRACT: To measure on a global scale the SV40 large T antigen-mediated changes in gene transcription in mouse embryo fibroblasts differing in the expression of p53. Samples of total RNA from 3T3 (wt p53) and 10-1 (p53-null) mouse embryo fibroblasts stably transfected with SV40 large T-antigen expressing pMYcLT vector (3T3 LT and 10-1 LT cells) or empty pMYsIG vector (3T3 IG and 10-1 IG cells) were subjected to gene expression analysis.

Abortive infection of BALB/c mouse embryo fibroblasts differing in p53 gene status (p53(+/+) versus p53(-/)(-)) with simian virus 40 (SV40) revealed a quantitatively and qualitatively decreased transformation efficiency in p53(-/-) cells compared to p53(+/+) cells, suggesting a supportive effect of wild-type (wt) p53 in the SV40 transformation process. SV40 transformation efficiency also was low in immortalized p53(-/-) BALB/c 10-1 cells but could be restored to approximately the level in immort ...[more]

Cell-type Specific Regulation of Gene Expression by Simian Virus 40 T antigens

Project description:SV40 transforms cells through the action of two oncoproteins, large T antigen and small t antigen. Small t antigen targets phosphatase PP2A, while large T antigen stimulates cell proliferation and survival by action on multiple proteins, including the tumor suppressors Rb and p53. Large T antigen also binds components of the transcription initiation complex and several transcription factors. We examined global gene expression in SV40-transformed mouse embryo fibroblasts, and in enterocytes obtained from transgenic mice. SV40 transformation alters the expression of approximately 800 cellular genes in both systems. Much of this regulation is observed in both MEFs and enterocytes and is consistent with T antigen action on the Rb-E2F pathway. However, the regulation of many genes is cell-type specific, suggesting that unique signaling pathways are activated in different cell types upon transformation, and that the consequences of SV40 transformation depends on the type of cell targeted.

GSEp53_v_Con

Project description:HMF3A cells, created from adult human mammary fibroblasts by immortalisation with a thermolabile SV40 large T antigen and the catalytic sub-unit of human telomerase, undergo co-ordinated induction of cellular senescence upon inactivation of T antigen. Given the importance of p53, we sought to determine what gene changes were affected if its activation was inhibited. To do this we used the Genetic Suppressor Element (GSE)56 which inhibits the transcriptional activity of p53 (Ossovskaya, 1996). The presence of the GSEp53 delayed the arrest of the HMF3A cells when LT was inactivated. However the cells did arrest. We thus examined the array profiles for 3A-GSEp53 cells after 2 and 7 days of LT inactivation (against 3A-GSEp53 cells at 33Â°C) and compared these to the profiles for 3A-puro cells. Keywords = p53 Keywords = LT antigen Keywords = fibroblast Keywords = senescence Keywords = Rb

Matrix reverses immortalization-mediated stem cell fate determination

Project description:Primary cell culture in vitro suffers from cellular senescence. We hypothesized that expansion on decellularized extracellular matrix (dECM) deposited by simian virus 40 large T antigen (SV40 LT) transduced autologous infrapatellar fat pad stem cells (IPFSCs) could rejuvenate high-passage IPFSCs in both proliferation and chondrogenic differentiation. In the study, we found that SV40 LT transduced IPFSCs exhibited increased proliferation and adipogenic potential but decreased chondrogenic potential. Expansion on dECMs deposited by passage 5 IPFSCs yielded IPFSCs with dramatically increased proliferation and chondrogenic differentiation capacity; however, this enhanced capacity diminished if IPFSCs were grown on dECM deposited by passage 15 IPFSCs. Interestingly, expansion on dECM deposited by SV40 LT transduced IPFSCs yielded IPFSCs with enhanced proliferation and chondrogenic capacity but decreased adipogenic potential, particularly for the dECM group derived from SV40 LT transduced passage 15 cells. Our immunofluorescence staining and proteomics data identify matrix components such as basement membrane proteins top candidates for matrix mediated IPFSC rejuvenation. Both cell proliferation and differentiation were endorsed by transcripts measured by RNASeq during the process. This study provides a promising model for in-depth investigation of matrix protein influence on surrounding stem cell differentiation.

Transcriptional perturbations caused by SV40 large T antigen and its fragments

Project description:The small genome of polyomaviruses encodes a limited number of proteins that are highly dependent on interactions with host cell proteins for efficient viral replication. The SV40 large T antigen (LT) contains several discrete functional domains that contribute to the viral life cycle, including the DNA binding and helicase domains. In addition, the LT the C-terminal region is required for lytic infection in certain restrictive cell types. To understand how LT affects the host cell to facilitate viral replication, we expressed full-length or functional domains of LT in cells and identified interacting cellular proteins and performed expression profiling. LT perturbed the expression of p53 target genes and subsets of cell-cycle dependent genes regulated by the DREAM and the B-Myb-MuvB complexes. To examine transcriptome perturbations directly in human cells, we generated expression constructs of each LT fragment. Full length and truncated LT containing N-terminal HA and FLAG epitope tags were expressed from the pMSCV retroviral vector and introduced into U-2 OS cells. Total RNA was isolated from three biological replicate U-2 OS stable cell lines and gene expression was assayed on Affymetrix Human Gene U133 Plus 2.0 arrays.

Mammary carcinomas in WAP-SV40 transgenic mice [aCGH]

Project description:Transgenic expression in mice of two synergistically acting SV40 early region encoded proteins, large (LT) and small (sT) tumor antigens, in the mammary epithelium recapitulates loss of p53 and Rb function and deregulation of PP2A-controlled mitogenic pathways in human breast cancer. In primiparous mice, WAP-promoter driven expression of SV40 proteins induces well and poorly differentiated mammary adenocarcinomas. We performed a correlative aCGH and gene expression analysis of 25 monofocal tumors, representing four histopathological grades, to explore the molecular traits of SV40-induced mammary tumors and to emphasize the relevance of this tumor model for human breast tumorigenesis. CGH analysis of 15 mammary carcinoma samples of the NP8 WAP-SV40 mouse line.

Expression of mutant p53 in Mammary carcinomas in WAP-SV40 transgenic mice

Project description:Upon induction, WAP-T mice express two synergistically acting SV40 early region encoded proteins, large (LT) and small (sT) tumor antigens in the mammary epithelium, recapitulating thereby the loss of p53 and Rb function and deregulation of PP2A-controlled mitogenic pathways in human breast cancer. In primiparous mice, WAP-promoter driven expression of SV40 proteins induces well and poorly differentiated (respectively low- and high-grade) mammary adenocarcinomas. We here studied the postulated mutant p53 (mutp53) 'gain of function' during mammary tumor development, progression and metastasis by crossing WAP-T mice with mutant p53 transgenic WAP-mutp53 mice.
