Abstract 943: Insulin-like growth factor-2 a potential target for screening and treatment in patients with triple negative breast cancer
2021
Triple-negative breast cancer (TNBC) affects only about 10-15% of women with breast cancer (BC) but accounts for almost 50% of all BC deaths. At this time, development of targeted treatments for TNBC are urgently needed. Insulin-like growth factor-2 (IGF2) is highly expressed in TNBCs and mediates its proliferative effects via two hormone receptors, insulin-like growth factor -1 receptor (IGF1R) and insulin receptor (IR). Using a TNBC tissue microarray (TMA) consisting of 159 archival clinical samples, we confirm that IGF2 is highly expressed in tumor tissue as compared to nearby normal tissue (P Citation Format: Nalo M.
