Objective: We aimed to investigate the signalling crosstalk of TNF-related apoptosis-inducing ligand, TRAIL death receptors, tumour protein p53, and programmed cell death (PDCD5) with IQGAPs. Also, we targeted the crosstalk between IQGAPs genes with decoy receptors, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and interleukins -8 (IL-8) and its receptor genes in a designed model of hepatocellular carcinoma induced in male Balb/c mice. Methods: The presence of HCC was confirmed by histological and morphological alterations. In parallel to the incidence of hepatic cancer, we found lung, heart, and kidney cancer after treatment with DEN. Results: Our results show that the expression of mRNA of IQGAP1, TRAIL decoy receptors, NF-κB, and IL-8 genes was elevated in hepatocellular carcinoma, as compared to normal liver tissue, while their expression was further up-regulated by increasing the dose of diethylnitrosamine. The expression of IQGAP2, TRAIL death receptors, p53, and PDCD5 was significantly down-regulated in HCC (p˂0.05). For confirmation of gene expression, protein levels of both IQGAP1 and P53 were measured by western blot analysis, which showed that diethylnitrosamine enhanced protein expression of IQGAP1 and diminished that of p53. Conclusion: IQGAPs have a direct signaling relationship with p53, IL-8, and TRAIL family. This interaction is recognized as a key signalling pathway for hepatocellular carcinogenesis.
