Expression and significance of transcription factor EBF3 in tissues of human primary hepatocellular cancer / 临床检验杂志

ABSTRACT

Objective To investigate the expression differences of mRNA and protein of early B-cell factor 3(EBF3) in the tissues between hepatocellular carcinoma(HCC) and distant noncancerous tissues and the clinical significance.Methods The expression levels of EBF3 mRNA in 18 pairs surgical specimens of HCC and their distant noncancerous tissues were detected by real-time fluorescence quantitative polymerase chain reaction(FQ-RT-PCR).Western blotting was used to detect the expression levels of EBF3 protein in 5 pairs surgical specimens of HCC and distant noncancerous tissues.Results The ratios of EBF3 mRNA tobeta2 microglobulin mRNA in eighteen liver cancerous tissues(0.52?0.17) were significantly higher than those in distant liver noncancerous tissues(0.28?0.23,t=3.56,P=0.0011).The average gray scale level of EBF3 in five liver cancerous tissues(26.35?14.06)were significantly higher than those in distant noncancerous tissues(7.86?8.47,t=2.52,P=0.036).Conclusion Theexpression levels of EBF3 mRNA and protein up-regulated in primary hepatocellular carcinoma,suggestting that EBF3 may contribute to occurrence of primary hepatocellular carcinoma.
