Abstract

Larimichthys crocea swim bladder is a traditional food and medicine widely used in China. The in vitro anticancer effects of polysaccharide of L. crocea swim bladder (PLCSB) in HCT‑116 human colon cancer cells was investigated by 3‑(4,5‑dimethylthiazol‑2‑yl)‑2,5‑diphenyltetrazolium bromide assay. At concentrations ranging between 0 and 800 µg/ml PLCSB, cancer cell viability was decreased by PLCSB in a concentration‑dependent manner. In particular, 400 µg/ml PLCSB significantly (P<0.05) induced apoptosis, which was demonstrated by 4,6‑diamidino‑2‑phenylindole staining and flow cytometry analysis. To elucidate the mechanisms underlying the anticancer effect of PLCSB in HCT‑116 cancer cells, the expression of apoptosis and metastasis‑associated genes was analyzed by reverse transcription‑polymerase chain reaction and western blot analysis. A total of 400 µg/ml PLCSB significantly induced apoptosis in HCT‑116 cells (P<0.05) via the upregulation Bax, p53, p21, apoptotic protease activating factor 1, caspase‑3, ‑8, and ‑9, as well as Fas and the downregulation of B‑cell lymphoma 2 (Bcl‑2), Bcl‑extra large and Fas ligand (L). The results of this study demonstrated that PLCSB exhibits an anticancer effect on HCT‑116 colon cancer cells, in vitro.
