p-STAT3

体外研究

1-Stearoyl-2-hydroxy-sn-glycero-3-PC (10-80 μM; 24-72 h) significantly reduced the viability of K562, HL-60, U937, and MDA-MB-231 cells.
1-Stearoyl-2-hydroxy-sn-glycero-3-PC (80 μM; 24 h) can induce apoptosis in K562, U937, and HL-60 cells, significantly increasing the sub-G1 phase cell population of K562 cells.
1-Stearoyl-2-hydroxy-sn-glycero-3-PC (80 μM; 24 h) induces caspase-9, caspase 3, and PARP cleavage in K562 cells, enhances the levels of acetylated histone H3 at Lys 18 and 23 sites, reduces HDAC3 expression, inhibits STAT3 phosphorylation at Ser 727 and Tyr 705 sites, and downregulates the expression of survival genes such as Cyclin D1, Cyclin E, Bcl xL, Bcl-2, and survivor.
