Article Title: Gamabufotalin Suppresses Colorectal Cancer Growth via Oxidative Stress-Induced Apoptosis and DNA Synthesis Inhibition

doi: 10.5812/ijpr-169859

Figure Lengend Snippet: In vitro experiments demonstrated that gamabufotalin (GA) has a dose-dependent inhibitory effect on colorectal cancer (CRC) cells. A, the chemical formula of GA; B, SW480, HCT-116, HT-29, NCM460, and 293T cells were treated with 0-20000 nM GA for 48 hours, and viability was initially determined using the CCK-8 kit. Each concentration point was repeated six times (n = 6). C, CRC SW480, HCT-116, and HT-29 cells were co-incubated with GA at concentrations ranging from 0 to 200 nM for 48 hours, and the relative cell viability of each experimental group was evaluated using the CCK-8 kit. D, the cell viability of SW480, HCT-116, HT-29, NCM460, and 293T cells was measured using the CCK-8 kit at a GA concentration of 50 nM. E, the cell viability of CRC SW480 and HCT-116 cells was measured under a serum concentration of 1% in the culture condition. F, SW480 cells were treated with GA for 48 hours, and the morphological changes in SW480 cells caused by GA were photographed using an inverted microscope. G, SW480 cells were treated with different concentrations of GA for 24 hours, and the width of the scratch was measured, and the cell scratch closure rate was calculated. Post hoc analysis using LSD was performed after one-way ANOVA to evaluate significance, ** P < 0.01.
