Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Polyoma virus, Large T antigen antibody [CM2B4] (AB307450)
Immunohistochemical analysis of paraffin-embedded human liver tissue labeling Polyoma virus, Large T antigen with ab307450 at 1/2000 (0.2115 ug/ml) followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Negative control : No staining on human liver. The section was incubated with ab307450 for 15 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin. Secondary antibody only control : Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Heat mediated antigen retrieval was performed with Citrate buffer (pH 6.0, Epitope Retrieval Solution 1) for 20 mins.

Western blot - Anti-Polyoma virus, Large T antigen antibody [CM2B4] (AB307450)
Negative control : 293T (PMID : 20444890). The expression profile is consistent with what has been described in the literature (PMID : 20444890). This blot was produced using a 4-12% Bis-Tris gel and MOPS buffer. The gel was run at 200V for 54 minutes and then transferred to a Nitrocellulose membrane at 25V for 10 minutes. The membrane was blocked for an hour using 3% milk and incubated overnight at 4°C with Mouse monoclonal [CM2B4] to Polyoma virus, Large T antigen ( ab307450) and Rabbit anti-ACTN4 (loading control, ab108198) at a 1/1000 and 1/20 000 dilution, respectively. Antibody binding was detected using Goat Anti-Mouse IgG H&L (IRDye® 800CW, green) and Goat Anti-Rabbit IgG H&L (IRDye® 680RD, red) secondary antibodies at a 1/20 000 dilution (1h at room temperature) before imaging. Blocking/Dilution buffer : 3% NFDM/TBST.

Biological function summary
Large T antigen acts as a multifunctional protein involved in both viral replication and cell transformation. It is critical for the assembly of replication complexes. TAg interacts with host proteins to promote cell proliferation and prevents apoptosis which is a programmed cell death. This interaction forms a complex that is important in driving the cell into S-phase where DNA replication occurs. Large T antigen mimics normal cellular signals to facilitate uncontrolled cell division.
Pathways
Large T antigen connects to significant regulatory mechanisms involved in cell cycle control. It acts in the RB tumor suppressor pathway by inactivating the retinoblastoma protein family including pRb. This disruption allows cells to bypass normal growth signals leading to continuous entry into the S-phase. Large T antigen also impacts the p53 pathway inhibiting this tumor suppressor protein and further promoting cell cycle progression and DNA replication similar to pathways seen in other oncogenes.
