Limonin inhibits the stemness of cancer stem-like cells derived from colorectal carcinoma cells potentially via blocking STAT3 signaling

Figure 1 Limonin inhibits cell viability and cell cycle distribution in colorectal cancer cells. A: After being cultured with 10-60 μmol/L limonin for 24 h, cell viability was measured by performing cholecystokinin octapeptide-8 and IC30 or IC50 was calculated; B: After being cultured with 20 or 40 μmol/L limonin for 24 h, cell cycle distribution was measured. ^aP < 0.05 vs Mock group.
