GAL and lung cancer: To assess whether Nav‐Gal and Navitoclax killed senescent cells by the same end mechanism, cisplatin‐induced senescent lung cancer A549 cells and palbociclib‐induced senescent melanoma SK‐Mel‐103 cells were treated with Navitoclax or Nav‐Gal (or vehicle) in parallel, with automated real‐time measurement of apoptosis study using a live‐cell analysis system.
