TNFSF10 and colonic neoplasm: A whole transcriptome analysis was carried out using microarrays, to elucidate the response of HT29 human colon cancer cells to a 6 h treatment combining TRAIL (100 ng/ml + 2 μg/ml anti-Flag M2 antibody) with propionibacterial culture supernatant (SN diluted to 1/2) or a mixture of propionate (30 mM) and acetate (15 mM) (C3/C2, the major metabolites used in the amounts present in the diluted SN).
