Abstract

Cervical cancer is the fourth most common cancer in women worldwide, and existing treatments cause severe side effects and great burdens. Thus, the development of safe, inexpensive therapeutic agents is necessary. Curcumin (Cur), a well-known natural product, exerts promising anti-cancer activities against various cancer types. However, its therapeutic efficacy is severely restrained due to rapid degradation, poor aqueous solubility, and low bioavailability. The objective of this study was to investigate the therapeutic potential of novel curcumin-loaded TPGS/F127/P123 mixed polymeric micelles (Cur@NPT100) for cervical cancer treatment. The Cur@NPT100 exhibited an average size of approximately 19 nm, a zeta potential of around -4 mV, a drug loading of 8.18 ± 0.36%, and an encapsulation efficiency of 79.38 ± 4.65%. Unlike free Cur, Cur@NPT100 are readily dispersed in aqueous medium, showing enhanced stability and a sustained release profile over a 6-day period. In vitro cell culture experiments revealed that TPGS/F127/P123 mixed polymeric micelles (NPT100) based nanocarriers substantially promoted the selective cellular uptake of Cur into HeLa cells rather than by non-cancerous NIH3T3 cells, inducing higher cytotoxicity and grea...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
