[Effect of CDK Inhibitor LS-007 on Acute Lymphoblastic Leukemia and Its Mechanism]

To study the effect of cyclin dependent kinase(CDK) inhibitor LS-007 on acute lymphoblastic leukemia and its mechanism.

The acute lymphocytic leukemia cell line was cultured and treated by LS-007, flavopiridol and ABT-199, then the changes of apoptosis-related factor mRNA and protein levels were detected by using mRNA quantitative PCR and Werstern blot.

quantitative PCR and Western blot detection showed that the levels of antiapoptotic protein decreased significantly in acute lymphoblastic leukemia cells after LS-007 treatment, and the pro-apoptotic effect of LS-007 combined with ABT-199 was much better.

LS-007 can affect the phosphorylation of RNA polymerase sites and promote cell apoptosis through changing the activities of CDK, thus having some positive significance for relieving acute lymphoblastic leukemia.
