There was a significant association between the expression level of Prx II and various factors, including tumor size, histological differentiation, the depth of invasion, the stage of tumor-node-metastasis (TNM) and lymph node metastasis in GC (P<0.05).
Our study demonstrated that miR-212-5p inhibits TNBC from acquiring the EMT phenotype by downregulating Prrx2, thereby inhibiting cell migration and invasion during cancer progression.
Finally, the significant correlation of PRRX2 expression with poor survival in 118 primary breast tumour samples (P = 0.027) and the increased PRRX2 expression in metaplastic breast carcinoma samples, which is pathogenetically related to EMT, validated the biological importance of PRRX2-enhanced migration and invasion and PRRX2-induced EMT.
