My drug treatment reduces mutated P53 and Plk1 protein expressions in MDA-MB-231 cells model, I know mutated P53 acts as a proto-oncogene. But I can not find a solid relation between P53 and Plk1.Could any one help me to get the clear idea?
I am unsure what do you mean with mutated p53, since there are many different mutations of p53 across different tumours. But Plk1 gene is usually activated in G2-phase and is indirectly repressed by p53/p21 after DNA damage in order to ensure G2/M arrest. Additionally, p53 activates ubiquitin ligase APC/C-Cdh1 to degrade Plk1.
Dear Khalil, very good question,,,,,,,,,,please go through the article on Plk1 regulates liver tumor cell death by phosphorylation of TAp63.
In deed, Polo-like kinase 1 (Plk1), a conserved Ser/Thr mitotic kinase, has been identified as a promising target for anticancer drug development because its overexpression is correlated with malignancy. If you dont find something you need,,I will write you later.
