DOIAbstract
The aim of this study is to identify the molecular mechanism of small-for-size graft injury through large-scale expression measurement of intragraft gene profile by carrier DNA (cDNA) microarray screening in liver transplantation. The studies compared 1,081 intragraft genes expression profiles using cDNA microarray of small-for-size grafts (<30% of recipient liver weight) with those of whole grafts (control group) 1, 3, and 24 hours after reperfusion in a rat liver transplantation model. Intragraft gene expression was detected by quantitative reverse-transcriptase polymerase chain reaction (RT-PCR). Hepatic ultrastructural features were shown by electron microscopy. In the small-for-size grafts, by cDNA microarray study, the vasoconstrictio...
