The expression of GLI1 RegIV mRNA in 12 pairs of PC tissues and adjacent normal tissues(A–B). DNA from the samples were collected from surgical biopsies, and relative GLI1 and RegIV mRNA expression were detected by qRT-PCR. Statistical correlation between the expression of GLI1 and RegIV mRNA in 12 pairs of PC tissues and adjacent normal tissues was analyzed by Spearman's test (C). All results were normalized to β-actin mRNA expression. The data are presented as the mean ± SD and were calculated by the paired t-test. Significantly different between two groups: *p<0.05. ** p<0.01. NS: not significant.
