Src Family Kinases as potential therapeutic targets for chemotherapy-resistant triple negative breast cancer


ABSTRACT: Here we quantified tyrosine phosphorylation (pTyr) mediated signaling networks in chemotherapy sensitive (CS) and resistant (CR) TNBC patient derived xenografts (PDX) to gain novel therapeutic insights. We identified Src Family Kinases (SFKs) as potential therapeutic targets in CR TNBC PDXs. Additionally, we performed pTyr analysis on tumor specimens derived from TNBC patients and observed lower prevalence of SFK driven tumors.

Neoadjuvant chemotherapy (NAC) remains the cornerstone of the treatment for triple negative breast cancer (TNBC), with the goal of complete eradication of disease. However, for patients with residual disease after NAC, recurrence and mortality rates are high and the identification of novel therapeutic targets is urgently needed. We quantified tyrosine phosphorylation (pTyr)-mediated signaling networks in chemotherapy sensitive (CS) and resistant (CR) TNBC patient-derived xenografts (PDX), to gai  ...[more]
