A tumor-suppressor function for NFATc3 in T-cell lymphomagenesis by murine leukemia virus.
Nuclear factor of activated T cell (NFAT) transcription factors play a central role in differentiation, activation, and elimination of lymphocytes. We here report on the finding of provirus integration into the Nfatc3 locus in T-cell lymphomas induced by the murine lymphomagenic retrovirus SL3-3 and show that NFATc3 expression is repressed in these lymphomas. The provirus insertions are positio...
متن کاملSpecific tumor suppressor function for E2F2 in Myc-induced T cell lymphomagenesis.
Deregulation of the Myc pathway and deregulation of the Rb pathway are two of the most common abnormalities in human malignancies. Recent in vitro experiments suggest a complex cross-regulatory relationship between Myc and Rb that is mediated through the control of E2F. To evaluate the functional connection between Myc and E2Fs in vivo, we used a bitransgenic mouse model of Myc-induced T cell l...
متن کاملChanges in Expression of miR-1297 and PTEN Tumor Suppressor Gene in T-cell Acute Lymphoblastic Leukemia
Background and purpose: T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood malignancy caused by changes in the precursors of T lymphocyte cells. The PTEN gene is one of the most common tumor suppressor genes that mutates in most human cancers, including T-ALL. Therefore, it is important to identify miRNAs that target the PTEN gene in T-ALL. For this purpose, in the present study, mi...
متن کاملSelection for loss of p53 function in T-cell lymphomagenesis is alleviated by Moloney murine leukemia virus infection in myc transgenic mice.
Thymic lymphomas induced by Moloney murine leukemia virus (MMLV) have provided many examples of oncogene activation, but the role of tumor suppressor pathways in these tumors is less clear. These tumors display little evidence of loss of heterozygosity, and MMLV is only weakly synergistic with the Trp53 null genotype, suggesting that viral lymphomagenesis involves mechanisms which do not requir...
متن کاملProduction of antigen-specific suppressive T cell factor by radiation leukemia virus-transformed suppressor T cells.
Hen egg-white lysozyme (HEL)-specific suppressor T cells induced in C57BL/6 mice have been selected by sequential passage over plates coated with goat anti-mouse Ig and HEL. These suppressor T cells, 80% I-J+, were infected in vitro with radiation leukemia virus (RadLV/Nu1) and injected intravenously into sublethally irradiated syngeneic recipients. After 4-6 months, 6 out of 20 injected mice d...
