Abstract LB-099: Metabolic vulnerabilities of mesenchymal-like EGFR-mutant NSCLC cells with acquired resistance to tyrosine kinase inhibitors
Abstract Despite the availability of the effective targeted therapies in lung cancer, such as EGFR tyrosine kinase inhibitors (TKIs), drug tolerance and acquired resistance are two common problems that negatively impact lung cancer patient survival. Consequently it is important to understand the molecular basis of the drug tolerance and resistance so that we could formulate effective strategies to ameliorate the efficacy of existing drug and to suppress the emergence of drug resistance. A burgeoning body of literature demonstrated that epigenetic changes by the methylation of DNA and histones are critical in acquired drug resistance, especially in those cancer cells with stem cell-like prop…
Metabolomics as a tool for the study of drug-induced hepatotoxicity
Drug-induced liver injury (DILI) is a major health and economic problem and the leading cause of hepatic dysfunction, drug failure during clinical testing and post-market withdrawal of approved drugs. Pre-clinical testing should be able to detect potential hepatotoxins early in the drug development process in order to minimize health risks and financial losses. Several liver-derived in vitro models have been developed to be used in pharmacology and toxicology research to understand the mechanism of DILI and to evaluate potential hepatotoxicity of new chemical entities. Although they fail to reproduce the complexity of a whole organ, their low cost, high reproducibility, and the possibility …
