From: Inactivation of miR-34a by aberrant CpG methylation in Kazakh patients with esophageal carcinoma
Average relative miR-34a expression level in ESCC compared with that in normal esophageal tissues. The expression level of miR-34a was measured by qRT-PCR and was normalized by U6RNA. Each sample was analyzed in triplicate, repeated three times. Error bars represent the standard error of mean, and asterisks represent a statistically significant difference (P < 0.0001).
