TNF and colon adenocarcinoma: The potential protective effects of FS and NFS against TNF-α-induced alterations were evaluated in HT-29, a human colonic adenocarcinoma cell line, exposed for 24 h to 5 ng mL−1 TNF-α following a 1-h pre-treatment with or without 0.08 and 0.4 mg mL−1 FS and NFS extracts.
