Figure 6From: Inhibition of the checkpoint kinase Chk1 induces DNA damage and cell death in human Leukemia and Lymphoma cellsLeukemia and lymphoma cell lines do not exhibit high endogenous expression levels of phosphorylated Chk1. (A) Untreated whole cell protein extracts were prepared from the indicated cell lines and the expression levels of various protein markers determined by western blotting. (B) Protein expression was quantified by densitometry and correlated with the cell line sensitivity to V158411. Circles, lung cell lines; squares, leukemia and lymphoma cell lines.Back to article page
