Expressions of Cthrc1 mRNA in paired NSCLC and adjacent normal tissues. a Relative expression levels of Cthrc1 mRNA in paired NSCLC and adjacent normal tissues. There is a statistically significant difference (P < 0.05). b On the basis of differentiation, NSCLC tissues were divided into two groups (Well and Moderate & Poor). The up-regulation of Cthrc1 was notably in Moderate & Poor group (P < 0.05). c In TNM stage of tumor tissues, the expression of Cthrc1 was successively increased (P < 0.05). d On the basis of lymph node metastases, the expression of Cthrc1 was significantly higher in N0 group than N1–N3 group (P < 0.05). e The expressions of miR-30b and Cthrc1 mRNA were negatively correlated (R2 = 0.734, P < 0.05)
