Abstract: Src has been one of the most studied proto-oncogenes. The cellular Src (c-Src) holds a critical role in several human malignancies and has emerged as a key factor that promotes tumor progression during the multistep process of colorectal cancer (CRC) pathogenesis. The robust activation of Src in CRC of aggressive phenotype and poor prognosis seems to be a subsequent event of a strong link between its deregulated activity and the tumor's cell adhesion properties, invasiveness and metastatic potential. The rarely detected genetic defects drive interest in signaling networks that control Src kinase activity and integrate the association of Src with receptor tyrosine kinases (RTKs), such as the epidermal growth factor receptor (EGFR). Therefore, a dynamic crosstalk is being formed with oncogenic capacity and therapeutic applications, because Src inhibition seems to sensitize previously unresponsive cancer cells to chemotherapy and anti-EGFR inhibitors. The present review explores the molecular basis behind Src inhibition in colorectal carcinomas. Furthermore, preclinical studies and clinical trials of Src inhibitors and combination regimens are discussed, providing new insights for further investigation and new therapeutic strategies.
