OBJECTIVE: To investigate peripheral blood monocyte (PBMC) gene expression profile in patients with fulminant hepatic failure (FHF) by cDNA microarray. METHODS: Microarrays consisting of 8,192 human cDNAs and labelled cDNAs prepared from PBMC in both 10 FHF patients and 10 asymtomatic surface antigen carriers (ASC) were applied to analyze gene expression. Relative ratios of gene expression in individuals were obtained by comparing the hybridization results, by GenePix 4000B scanning and by ImaGene3.0 software analysis, of Cy5-labelled cDNA from FHF patients with those of Cy3-labelled cDNA from...
