Expression of mature miR-130b in ESCC tissue specimens. The expression of miR-130b was detected by TaqMan qRT-PCR in 20 ESCC and matched normal esophageal tissue samples. The expression of miR-130b is presented on a 2-ΔCT (×100) scale and normalized against the endogenous control U6. (A) Paired comparison of miR-130b expression in ESCC tissue and matched normal tissue. (B) Scatter plots with merged data.
