Modulating Cell-to-Cell Variability and Sensitivity to Death Ligands by Co-Drugging

Flusberg DA, and Sorger PK (2013). Modulating Cell-to-Cell Variability and Sensitivity to Death Ligands by Co-Drugging. Phys Biol 10(3), 035002. PMC3775495 PMID: 23735516. Abstract

TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) holds promise as an anti-cancer therapeutic but efficiently induces apoptosis in only a subset of tumor cell lines. Moreover, even in clonal populations of responsive […]
