Web26 mei 2024 · Suppressing PI3Kδ reduces E2F1 expression also in non-EBV infected tumour cells, demonstrating that this pathway is also active in rapidly proliferating cells. Treating transgenic EBNA1-induced B cell lymphomas with the PI3Kδ kinase inhibitor CAL-101 (Idelalisib) reduce the levels of E2F1 and c-myc and causes cell death . Web18 nov. 2011 · E2F1 is one of the transcriptional targets of c-MYC. The association of PBK expression with aggressive hematologic neoplasms and BL in particular, suggested a possible role of a c-MYC-E2F1-PBK axis in the pathogenesis of hematological malignancies.

WebPrevious work has shown that the Myc transcription factor induces transcription of the E2F1, E2F2, and E2F3 genes. Using primary mouse embryo fibroblasts deleted for individual E2F genes, we now show that Myc-induced S phase and apoptosis requires distinct E2F activities. The ability of Myc to induce S phase is impaired in the absence of either E2F2 … WebE2F2 is the second prototypical activator E2F and has significant homology to E2F1. In tumor development and evolution, E2F2 has conflicting roles. Previously, we have shown that loss of E2F2 delays the onset of tumors in a Myc overexpression model, where Myc was driven by the long terminal repeat (LTR) promoter of the mouse mammary tumor …
