Nitric oxide/paclitaxel micelles enhance anti-liver cancer effects and paclitaxel sensitivity by inducing ferroptosis, endoplasmic reticulum stress and pyroptosis.

The objective of this study was to investigate the anticancer activities of biodegradable polymeric micelles composed of monomethoxy poly(ethylene glycol), polylactic acid, and nitric oxide (mPEG-PLA-NO) loaded with paclitaxel (PTX) as a nanomedicine delivery system. We aimed to compare the anticancer effects of these NO/PTX micelles with PTX alone and elucidate their mechanism of action. We evaluated the impact of NO/PTX and PTX on cell viability using Cell Counting Kit-8 (CCK8) assays conducted on the Bel-7402 liver cancer cell line.
