PIN1 positively modulates cervical cancer cells malignant phenotypes. (A, B and C) Cell Proliferation, apoptosis and invasion in Siha cells, respectively (a1, b1 and c1 Normal controls). (a2, b2 and c2) A Knockdown of PIN1 decreased cell proliferation, increased cell apoptosis, decreased cell invasion, which significantly decreased malignant phenotypes of Siha cells. All experiments were performed at least three times.
