Abstract
PTP1B and T cell PTP (TC-PTP) are protein tyrosine phosphatases (PTPs) that share high sequence and structural homology yet play distinct physiological roles. While PTP1B plays a central role in metabolism and is an attractive drug target for obesity and type 2 diabetes, TC-PTP is necessary for the control of inflammation. In this review, we will discuss the growing evidence for the involvement of PTP1B in cancer, while proposing a role for TC-PTP in inflammation-induced tumorigenesis. Given the challenge of developing inhibitors specific for PTP1B alone, it is necessary to consider both enzymes and their roles in various cancer models.
