[Three novel genes BM390716, BI274487 and AA963863 involed in extracellular matrix metabolism of eight rat regenerating liver cell types].

To explore the roles of three novel genes BM390716, BI274487 and AA963863 and the correlation between them during liver regeneration of rats, eight kinds of liver cells were isolated using the combined percoll density gradient centrifugation and immunomagnetic bead method. Rat genome 230 2.0 array was used to detect the changes in expression of genes involved in metabolism of extracellular matrix and the novel genes in rat genome. Correlation between sequence homology, co-expression of the above genes and the physiological activities they involed in were analyzed using Microsoft Excel and BLAST software. The results showed that BM390716 was homologous to and co-expressed with pparα, BI274487 was homologous to and co-expressed with timp2, and AA963863 was homologous to and co-expressed with csgalnact1. It is predicted that BM390716, BI274487, and AA963863 were involved in extracellular matrix metabolism in eight types of rat regenerating liver cells.
