KLF13 knockdown in Nalm6 cells. Nalm6 cells were transduced with either scrambled shRNA or 2 distinct KLF13 shRNAs using lentivirus. (A) Time course of KLF13, c-MYB, BCL2, BIM, and Actin protein expression following 1 µM dexamethasone treatment in vitro. (B) Quantified expression of c-MYB normalized to actin and then to Scr 0-hour samples. N = 3; *P < .05. (C) Quantified expression of BCL2 normalized to actin and then to Scr 0-hour samples. N = 3; *P < .05. Dex, dexamethasone; Scr, scrambled shRNA; SH1, KLF13 shRNA 1; SH2, KLF13 shRNA 2.
