We found that the cisplatin-resistant lung carcinoma cell line A549/CDDP had increased levels of the phosphorylated gap junction protein Cx43 and SRC tyrosine kinase, and low levels of total Cx43 protein and reduced gap junction formation.
Molecular alterations of <i>YES1</i>, a member of the SRC (proto-oncogene tyrosine-protein kinase Src) family kinases (SFKs), can be found in a significant subset of patients with lung cancer.<b>Objectives:</b> To evaluate <i>YES1</i> (v-YES-1 Yamaguchi sarcoma viral oncogene homolog 1) genetic alteration as a therapeutic target and predictive biomarker of response to dasatinib in NSCLC.<b>Methods:</b> Functional significance was evaluated by <i>in vivo</i> models of NSCLC and metastasis and patient-derived xenografts.
Here, we evaluate the potential involvement of SRC family kinases (SFK) in lung cancer biology and assess the possible benefits of their inhibition as a therapeutic approach.
We show that DDR2 and SRC are binding partners, that SRC activity is tied to DDR2 activation, and that dual inhibition of both DDR2 and SRC leads to enhanced suppression of DDR2 mutated lung cancer cell lines.
In summary, this study provides the first clues regarding the role of miR-203 as a tumor suppressor in lung cancer cells through the inhibition of SRC translation.
As shown recently, ID1 is positively regulated by the tyrosine kinase SRC in lung carcinoma cell lines and with that appears as a potential new therapeutic target in non-small cell carcinoma (NSCLC).
Based on the importance of EGFR signaling in lung cancer, the known cooperation between EGFR and Src proteins, and evidence of elevated Src activity in human lung cancers, we evaluated the effectiveness of a novel orally bioavailable Src inhibitor dasatinib (BMS-324825) in lung cancer cell lines with defined EGFR status.
