MiR-610 is downregulated in HCC and correlates with HCC progression and survival. A, Correlation between miR-610 expression in different grades of HCC assessed by real-time PCR. Box boundaries represent lower and upper quartiles, respectively; lines within boxes and whiskers denote median and extremum, respectively. B, Correlation between miR-610 levels and overall survival by Kaplan–Meier analysis of patients with low (<median) or high (>median) miR-610 expression. C, MiR-610 expression levels in HCC cell lines compared with normal human hepatic cells. D, Comparison of miR-610 levels in 10 paired HCC tissues (T) and their adjacent noncancerous tissues (ANT). Average miR-610 expression was normalized using U6 expression. Bars represent the means ± SD of three independent experiments. *P <0.05.
