ABSTRACT
Objective:
To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:
The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:
IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:
Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.
