PKCδ-mediated SGLT1 upregulation confers the acquired resistance of NSCLC to EGFR TKIs.

Oncogene 2021 Jun 21. Epub 2021 Jun 21.

Center for Molecular Medicine, Research Center for Cancer Biology, and Graduate Institute of Biomedical Sciences, China Medical University, Taichung, Taiwan.

The tyrosine kinase inhibitors (TKIs) targeting epidermal growth factor receptor (EGFR) have been widely used for non-small cell lung cancer (NSCLC) patients, but the development of acquired resistance remains a therapeutic hurdle. The reduction of glucose uptake has been implicated in the anti-tumor activity of EGFR TKIs. In this study, the upregulation of the active sodium/glucose co-transporter 1 (SGLT1) was found to confer the development of acquired EGFR TKI resistance and was correlated with the poorer clinical outcome of the NSCLC patients who received EGFR TKI treatment.
