Targeting peptidyl-prolyl isomerase PIN1 to inhibit tumor cell aggressiveness

摘要

Purpose: Because the peptidyl-prolyl isomerase PIN1 interacts with multiple protein kinases and phosphoproteins into a network orchestrating the cellular response to various stimuli, there is an increasing interest in exploiting its potential as therapeutic target. In the present study, the effect of targeting PIN1 was investigated in 2 human cancer cell lines characterized by increased aggressive potential, high expression of erbB receptor family members, and defective p53.
