Under the TNFα overexpression, significant upregulation of two genes was observed: proinflammatory cytokine IL6 gene in melanoma cells A375 and gene for pro-apoptotic ligand TRAIL in colorectal carcinoma cells HT29, both mediated by TNFα/TNFR1 signaling. Here, TNFRSF1A is linked to colorectal carcinoma.
