CTSC and glioma: We found that CTSC expression was significantly inhibited by both drugs at concentrations of 5, 10, and 20 μM (P < 0.05), with the inhibitory effect of PL being more obvious than that of SCO (Fig. 10c, d), accompanied by the obviously reduced proliferation of glioma cells (data not shown), indicating two novel drugs targeting on CTSC for the treatment of glioma.
