In this study, the growth-inhibitory effect of polysaccharide (1,3)(1,4)-β-d-glucan from oat, Avena sativa L. grains was explored on the human skin melanoma HTB-140 cells in vitro. The oat β-d-glucan (OBG) exerted cytotoxic action on HTB-140 cells. After 24 h of incubation, LD50 (concentration at which 50% of the cells were found dead) was obtained of 194.6 ± 9.8 μg/mL. The oat β-d-glucan caused a concentration-dependent increase of caspase-3/-7 activation and appearance of phosphatidylserine on the external surface of cellular membranes where it was bound to annexin V-FITC, demonstrating the induction of apoptosis. Intracellular ATP level decreased along with the mitochondrial potential, which suggested a mitochondrial pathway of apoptosis. A cell cycle analysis showed increase in the number of apoptotic cells, increase in the number of cells in G1 phase and decrease in the number of cells in G2/M. Although the detailed mechanism for the anti-tumor activity of the oat β-d-glucan still needs further investigation, this study provides preliminary insights into this direction along with perspectives of developing it as an anti-tumor agent.
