The SARS-CoV-2 B.1.617 lineage variants, Kappa (B.1.617.1) and Delta (B.1.617.2, AY) emerged during the second wave of infections in India, but the Delta variants have become dominant worldwide and continue to evolve. Here, we compared B.1.617 variants for neutralization...

MY-5445, a phosphodiesterase type 5 inhibitor, resensitizes ABCG2-overexpressing multidrug-resistant cancer cells to cytotoxic anticancer drugs.

American journal of cancer research

PMID: 32064159
Am J Cancer Res. 2020 Jan 01;10(1):164-178. eCollection 2020.

The overexpression of one or multiple ATP-binding cassette (ABC) transporters such as ABCB1, ABCC1 or ABCG2 in cancer cells often leads to the development of multidrug resistance phenotype and consequent treatment failure. Therefore, these transporters constitute an important target...

Tivantinib, A c-Met Inhibitor in Clinical Trials, Is Susceptible to ABCG2-Mediated Drug Resistance.
