Figure 1. Relative expression of the lncRNA AOC4P in HCCs and its clinical significance.
A. The expression of AOC4P was examined in 108 paired human HCC and noncancerous normal tissues via qRT-PCR. GAPDH expression was assessed as an internal control. The results were presented as the fold-change in AOC4P expression tumor tissues relative to that in normal tissues. The expression of AOC4P was significantly lower in tumor tissues than in normal tissues (p < 0.001). B. In situ hybridization for AOC4P in HCC and in noncancerous normal tissues. AOC4P expression was notably reduced in HCC samples. C and D. AOC4P expression was significantly lower in patients with more advanced pathological stage tumors and with larger tumor size. E and F. Kaplan-Meier curve presenting the disease-free survival and the overall survival of HCC patients exhibiting high or low AOC4P expression. Lower AOC4P expression levels (relative expression level < 0.25) in the tumor tissues were associated with a poor prognostic outcome.
