In addition, we find that in comparison with KSR1 (-/-) mouse embryonic fibroblasts expressing wild type KSR1 (WT-KSR1), cells expressing a cleavage-resistant KSR1 protein (DEVA-KSR1) exhibit reduced apoptotic signaling in response to tumor necrosis factor-alpha/cycloheximide treatment.

Cells expressing high levels of Nm23-H1 exhibited increased KSR1 degradation in the presence of either cycloheximide or an Hsp90-directed drug currently in clinical trial, 17-allylamino-17-demethoxygeldanamycin (17-AAG).

Further, the upregulation of KSR-1 gene by 1,25D is competed by ZK159222, an antagonist of vitamin D receptor (VDR) action, and can occur in the presence of protein synthesis inhibitor cycloheximide, showing that the effect is direct.
