Palbociclib resistant
WebAug 22, 2024 · Two patterns of resistance to palbociclib were observed: Partially resistant A375AR and HT144AR cells continued to proliferate while on palbociclib treatment, but at a slower rate than untreated control cells, whereas, in completely resistant CHL1AR and C002AR cells, palbociclib had no effect on cell proliferation. Fig. 1. WebFeb 25, 2024 · By looking at individual cancer cells, the research team found that cells that were resistant to palbociclib‒nanoparticles had reduced activity of a protein called mTOR. The scientists reasoned that while lower mTOR activity might help cancer cells resist palbociclib treatment, they may be unable to survive if mTOR activity is wiped out entirely.
