However, whether these identified genes are particularly associated with HBV-related HCC remains unknown. The aim of this study was to investigate the differential gene expression between HBV-related HCC tissues and adjacent noncancerous tissues. Methods cDNA microarray was used to detect the differential gene expression profile in the HBV-related HCC tissues and adjacent noncancerous tissues, and reverse transcription-polymerase chain reaction （RT-PCR） was performed to verify the differential expression of candidate genes obtained from cDNA microarray experiment. Results In this study, 1369 genes or expressed sequence tags （ESTs） including 121 genes or ESTs with at least two-fold expression alterations between cancerous and noncancerous tissues were identified. Special AT-rich sequence binding protein 1 （SATB-1） expression was positive in 73% （16/22） of cancerous tissues and negative （0/22） in all noncancerous tissues of HBV-related HCC patients. Transmembrane 4 superfamily member 1 （TM4SF-1） expression was positive in 86% （19/22） of cancerous tissues and negative （0/22） in all noncancerous tissues. Suppression of tumorigenicity 14 （ST-14） expression was positive in 73% （16/22） of noncancerous tissues in patients with HBV-related HCC and negative in all HCC tissues （0/22）. Conclusion This study provided the gene expression profile of HBV-related HCC and presented differential expression patterns of SATB-1, TM4SF-1 and ST-14 between cancerous and noncancerous tissues in patients with HBV-related HCC.展开更多
