Objective: To assess the potential role of tissue inhibitor of metalloproteinase 3 as a staging marker of hepatocellular carcinoma.
Method: The experimental study was conducted at Faculty of Pharmacy, Kafrelsheikh University, Egypt, from December 2020 to March 2022 after approval from the Faculty of Pharmacy, Kafrelsheikh University, Egypt, and comprised male albino rats. The subjects were divided into 4 groups. The control group was administrated a single intraperitoneal injection of normal saline, while the other groups were generated post-induction of hepatocellular carcinoma. The induction was done by injecting rats intraperitoneally with a single dose of 200mg/kg diethyl nitrosamine, followed by the administration of 0.05% phenobarbital sodium in drinking water daily. Rats were euthanised at 8, 16 and 24 weeks after the injection to obtain three groups related to the 3 stages of hepatocellular carcinoma. Serum was used for measuring the alpha protein level. Liver homogenates were used for the assessment
of the hepatic tissue inhibitor of metalloproteinase 3 expression, B-cell lymphoma 2-associated X protein expression, and the hepatic content of matrix metalloproteinase -9 and cyclin D1. Data was analysed using Graph Prism 8.
Results: Of the 24 rats with weight range 120-130g, 6(25%) were in each of the 4 groups. The relative protein and messenger ribonucleic acid tissue inhibitor of metalloproteinase 3 expressions were significantly decreased in the intervention groups compared to the control group, with more decline as the hepatocellular carcinoma stage increased. The matrix metalloproteinase -9 and cyclin D1 concentrations and the relative hepatic protein Ki67 expression were significantly raised in the intervention groups compared to the control group (p<0.05). The relative expression of hepatic B-cell lymphoma 2-associated X protein was markedly decreased in the intervention groups
compared to the control group (p<0.05).
Conclusion: Tissue inhibitor of metalloproteinase 3 might be a promising diagnostic and staging biomarker in hepatocellular carcinoma.
