Let-7b expression in HCC tissues. a RT-PCR was performed to detect let-7b expression in adjacent nontumor and tumor tissue of HCC patients. Data from three replicates are shown as the means (± SD). ***P < 0.001. b, c. Overall survival and estimated cancer-free survival according to the expression of let-7b in 94 cases of HCC (Kaplan–Meier method)
