WebThe effects of ABE and DOX converge on the Rb pathway. ABE inhibits cyclin-dependent kinase 4/6 (CDK), leading to a reduction in pRb. 18 DOX exposure initially increases pRb, but DNA damage leads to a reduction in Rb-pathway activity 26–28 and a delayed decrease in pRb. The CDK-pRb pathway is described using the following equations: (9) (10 ... WebOct 25, 2024 · At the same time, E6 binds p53 by promoting its degradation, which will cause the release of the Sp1 transcription factor, and also the impairment of p53-mediated interference with the pRb pathway. In fact, p53 prevents the phosphorylation of pRb; thus, the consequent activation of E2F.
