Loss of VOPP1 Contributes to BET Inhibitor Acquired Resistance in Non-Small Cell Lung Cancer Cells. (PubMed, Mol Cancer Res)
To investigate the mechanisms of acquired resistance to BET inhibitor (BETi)s, we generated a series of drug resistant sublines by exposing non-small cell lung cancer (NSCLC) NCI-H1975 cells to the BETi ABBV-075...Through combined treatments with BETis and BCL-2 inhibitors (BCL-2is), we demonstrated that BCL-2is synergistically sensitized the resistant cells to BETis. Implications: Based on these results, for the first time, we establish a causal link from VOPP1 loss to BCL-2 gain and then to BETi resistance, which provides new insights into BETi resistance and paves the way for further testing to circumvent BETi resistance.
