Effect of various GSK3 inhibitors on lymphoma cell viability and PARP cleavage: HS-Sultan (A,D), Karpas-299 (B,E), and HH (C,F) cells were exposed to a panel of small molecule GSK3 inhibitors. Doxorubicin, an anthracycline chemotherapeutic, was used as a positive control. Cell viability assessments were performed using the MTS assay following a 72-h exposure to the compounds. PARP cleavage assays (marker of apoptosis) were performed on lysates generated after 24 h exposure to compounds. Quantification of PARP blots from 3 separate experiments is provided for HS-Sultan (G), Karpas-299 (H), and HH (I) cells
