PRDM8 and leukemia: In the present study, there was a significant upregulation of PRDM8 (p < 0.044) and RAP1GAP (p < 0.029) in TQ-treated HL60 leukemia cells, suggesting that TQ inhibited HL60 cell growth and suppressed c-Myc expression by inhibition of JAK/STAT and PI3K/AKT/mTOR signaling through upregulation of PRDM8 and RAP1GAP.
