Reduced lncRNA TP73-AS1 up-regulates PTEN and declines Akt phosphorylation in HCC tissues of mice after radiotherapy. a, lncRNA TP73-AS1 expression of mice in each group before and after radiotherapy; b, mRNA expression of PTEN of mice in each group before and after radiotherapy; c, protein expression of PTEN of mice in each group before and after radiotherapy; d, protein expression of pAkt/Akt of mice in each group before and after radiotherapy; e, protein electrophoregrams of each group. * P < 0.05 vs the blank group, # P < 0.05 vs at dose of 0 Gy in the same transfected cells.
