ABSTRACT
Objective To study the relationship between Ephrin-A1 and its receptor with angiogenesis in hepatocellular carcinoma(HCC).Methods Immunohistochemistry staining method(S P methods)and reverse transcription polymerase chain reaction(RT-PCR) were used to determine the protein and mRNA expression of Ephrin-A1 and its receptor EphA1、EphA2 in tumor tissues and their corresponding adjacent liver tissues from 52 HCC patients;then,analyse of the relationship between Ephrin-A1 and clinicopathologyfactor and microvessel density(MVD) in HCC was made.Results The protein expression rate of Ephrin-A1 and EphA1,EphA2 in HCC was 59.6%(31/52),53.8%(28/52)and 17.3%(9/52),respectively,but in the paired liver tissues adjacent to HCC the expression rate was 23.1%(12/52),and respectively.The protein expression rate of Ephrin-A1 and EphA1 was significantly higher than that in the paired liver tissues adjacent to HCC(P0.05).The mRNA express rate of Ephrin-A1 and EphA1 in HCC [67.3%(35/52) and 73.7%(38/52)] were prominently higher than those in the paired liver tissues adjacent to HCC [42.3%(22/52) and 48.1%(25/52)](P0.05).The higher expression of Ephrin-A1 was correlated with the AFP level and thrombus in the portal vein(P
