Abstract:
Objective To explore the association of expression of transporter associated with antigen processing(TAP1),tumor necrosis factor-alpha(TNF-α)with occurrence and development of HBV-related hepatocellular carcinoma(HCC).Methods The expression of TAP1 and TNF-α in 35 liver carcinoma tissues,and 10 normal liver tissues were detected with immunohistochemical EnVision method,The expression and clinical significance of TAP1,TNF-α in HBV-related HCC were analyzed.Furthermore,the association of respective expression quantity with pathological typing of HCC was analyzed.Results The expression of TAP1,TNF-α was negative in hepatocytes of normal liver tissues.91.4% of HCC tissues expressed TAP1.There was significantly statistical difference in expression of TAP1 between HCC tissues and the normal hepatic tissues(P < 0.05);60% of HCC tissues expressed TNF-α.There was statistical difference in expression of TNF-α between HCC and the normal hepatic tissues(P < 0.05),and the positive expression rate of TNF-α in well-differenciated HCC tissues was significantly higher than that in poorly-differenciated ones(P < 0.05).Conclusion TAP1-related MHC-Ⅰ restricted antigen processing pathway was possibly normal in HBV-related HCC.The expression quantity of TNF-α was associated with the occurrence and degree of pathological differentiation of HBV-related HCC.
