TP53 and cervical cancer: The resulting ursolic acid-capped gold nanoparticles were embedded in poly(DL-lactide-co-glycolide) (PLGA) and tested on cervical cancer cell lines CaSki, HeLa, C4-1, and SiHa; experimental data indicated a significant suppression of cervical cancer cell proliferation and metastasis tendency via apoptosis induction by caspase and p53 activation and anti-apoptosis-related signals suppression (138).
