To investigate whether the differentiation-promoting effect of wogonoside on primary AML cells is dependent on PLSCR1 expression, cells (samples #2 and #19) were transfected with PLSCR1 small interfering RNA (siRNA; #1 and #2) and the efficacy of transfection monitored using western blotting. The gene discussed is PLSCR1; the disease is acute myeloid leukemia.
