Figure 4. HULC is able to increase the expression of E2F1.
A., B. The expression of E2F1 was examined by Western blot analysis in HepG2 and H7402 (or HepG2.2.15) cells transfected with pcDNA3.1-HULC (or si-HULC-1). The transfection efficiency of HULC (or si-HULC-1) was detected by qRT-PCR. C. The correlation between E2F1 mRNA levels and HULC mRNA levels was detected by qRT-PCR in 60 HCC tissues (P < 0.001, r = 0.962, Pearson's correlation). *P < 0.05; **P < 0.01; Student's t test.
