A. Jeko-1 cells and HL-60 cells were transfected with JARID1BsiRNA. A. Jeko-1 cells were transfected with JARID1B siRNA after 24 hours in fluorescence microscope (left), transfection efficiency was 96% ± 3.31% (n = 5). HL-60 cells were transfected with JARID1B siRNA after 24 hours in fluorescence microscope (right), transfection efficiency was 93% ± 2.56% (n = 5). B. The expression of JARID1B mRNA by different concentrations of siRNA in Jeko-1 and HL-60 cell line. After 24 hours transfection of JARID1B, the amplification of JARID1B mRNA attenuated with concentration dependent manner. Amplification of JARID1B was (1.07 ± 0.15) with 60 nmol/L, (0.63 ± 0.17) with 120 nmol/L, (0.22 ± 0.7) with 240 nmol/L respectively in Jeko-1, compared to control (1.25 ± 0.13), χ2 = 12.81, P < 0.05 (upper). Amplification of JARID1B was (0.87 ± 0.15) with 30 nmol/L, (0.56 ± 0.09) with 60 nmol/L, (0.12 ± 0.03) with 120 nmol/L respectively in HL-60, compared to control (1.13 ± 0.15), χ2 = 23.25, P < 0.05 (lower).
