NR0B2 and cancer: To assess whether the growth inhibitory effects of polysaccharide fractions on cancer cells were associated with apoptosis, the most effective fraction–cancer cell combinations (SHP-1.7/HeLa, SHP-1.0/B16, SLP-1.3/A549, SLP-1.3/HepG2, and UPP-0.5/SH-SY5Y) were selected to measure their apoptosis-inducing effects.
