Abstract

Selenium nanoparticles (SeNPs) are recently emerging as promising anticancer agents because of their high bioavailability, low toxicity and remarkable anticancer activities. However, the effects of surface physicochemical properties on the biological actions remain elusive. Herein we decorated SeNPs with various water-soluble polysaccharides extracted from various mushrooms, to compare physical characteristics and anticancer profile of these SeNPs. The results showed that the prepared spherical SeNPs displayed particle sizes at 91-102 nm, and kept stable in aqueous solution for up to 13 weeks. However, different decoration altered the tumor selectivity of the SeNPs, while gastric adenocarcinoma AGS cells showed relative highest sensitivity. Moreover, PTR-SeNPs demonstrated potent in vivo antitumor, by inducing caspases- and mitochondria-mediated apoptosis, but showed no obvious toxicity to nomal organs. Taken together, this study offers insights into how surface decoration can tune the cancer selectivity of SeNPs and provides a basis for engineering particles with increased anticancer efficacy.

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.
