Injuries of intestinal epithelial crypt cell-6 (IEC-6) and colorectal adenocarcinoma 2 (Caco-2) cells as models were induced by tumor necrosis factor-α stimulation in vitro.
Transient transfection gene reporter assay performed in TNF-α-stimulated HT-29 human colorectal adenocarcinoma cells indicated that mangiferin inhibits NF-κB transcriptional activity in a dose-dependent manner.
The systemic tumor necrosis factor alpha (TNFalpha) gene therapy was efficacious in the experimental treatment of established A431 epidermoid carcinoma, C33a cervix carcinoma, and LS174T colorectal adenocarcinoma.
