The nuclear transcription factor Y subunit beta (NFYB (显示 NFYB 蛋白))-E2F transcription factor 1 (E2F1) pathway displays a crucial role in the chemoresistance ofoxaliplatin-resistant colorectal cancer (OR-CRC (显示 CALR 蛋白)) by inducing the expression and activation of checkpoint kinase 1 (CHK1 (显示 CHEK1 蛋白)), suggesting a possible therapeutic target for oxaliplatin resistance in CRC (显示 CALR 蛋白).
If, as expected, the consequences of the deregulation of the CDKN1C (显示 CDKN1C 蛋白)-E2F1-TP53 (显示 TP53 蛋白) axis were the same as those experimentally demonstrated in mouse models, the disruption of this axis might be useful to predict tumor aggressiveness, and to provide the basis towards the development of potential therapeutic strategies in human Precursor T-cell lymphoblastic lymphomas

PPM1B (显示 PPM1B 蛋白) plays a negative role in the activation of the p38 (显示 CRK 蛋白)-RB1 (显示 RB1 蛋白)-E2F1 pathway and that targeting PPM1B (显示 PPM1B 蛋白) could be useful in certain types of cancer by stimulating chemotherapy-induced cell death.
Studied impact of BET proteins and E2F transcription factor 1 (E2F1) in neoplastic genetic transcription in glioblastoma.
E2F1 knockdown decreased the expression of discoidin domain receptor 1 (DDR1) which plays a crucial role in many fundamental processes such as cell differentiation, adhesion, migration and invasion.
Our data imply that downregulation of E2F1 may be a key factor in the celastrol-mediated inhibitory effects in HepG2 cells, and celastrol can serve as a leading compound for the development of compounds designed to inactivate E2F1 for hepatocellular carcinoma therapy

S6K1 interacts with retinoblastoma protein RBR via its N-terminal RBR binding motif, promotes its nuclear localization and consequent RBR-dependent repression of cell cycle genes through transcription factor E2FB.
The Arabidopsis (Arabidopsis thaliana) DEL1 gene was identified as a transcriptional target of the classical E2Fb and E2Fc transcription factors.
The authors found that S6K1 associates with the Retinoblastoma-related 1 (RBR1)-E2FB complex and this is partly mediated by its N-terminal LVxCxE motif.
Results suggest that E2FB is one of the key targets for auxin to determine whether cells proliferate or whether they exit the cell cycle, enlarge, and endoreduplicate their DNA.
AtE2Fa and AtE2Fb have specific expression patterns and may play similar but distinct roles during cell cycle progression.
The protein encoded by this gene is a member of the E2F family of transcription factors. The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. The E2F proteins contain several evolutionally conserved domains found in most members of the family. These domains include a DNA binding domain, a dimerization domain which determines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F2 and E2F3, have an additional cyclin binding domain. This protein binds preferentially to retinoblastoma protein pRB in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent/independent apoptosis.
