A Selenium-Modified Ginseng Polysaccharide Promotes the Apoptosis in Human Promyelocytic Leukemia (HL-60) Cells via a Mitochondrial-Mediated Pathway

A ginseng polysaccharide was extracted, purified, and modified by nitric acid-selenious acid (HNO3-H2SeO3) method to yield one selenylation-modified polysaccharide (sGP). We reported for the first time the anticancer potential of sGP on the human promyelocytic leukemia HL-60 cell line and evaluated its relevant underlying mechanism. Our results showed that sGP markedly inhibited the growth of HL-60 cells via induction of apoptosis. The event of...
