Abstract:
Objective To construct the genes expression profile database of experimental autoimmune encephalomyelitis (EAE) mice model and to screen the high candidate genes with microarray analysis. Methods Polymerase chain reaction (PCR) products on behalf of 4 096 genes from mixed mice tissue library were assembled on the modified Oako glass slide. The general RNA from 6 EAE mice model and 6 normal mice head was transcripted into cDNA by RT-PCR and labelled with cy-3 and cy-5.6 groups each consist one EAE mice and a control. These two probes were mixed and hybridized with the above mentioned gene chips. Scan array 4000 was used for scanning the hybridizing signals and GenePixPro 3.0 for date analysis. Results Of the total 4 096 genes monitored, 43 genes in group one showed changes in expression level of the ratio outside 0.5 and 2, 30 genes differed in group two, 176 genes changed in group three, 76 in group four, 294 in group five and 129 in group six. Conclusions The results showed the consistent different genes expression throughout the EAE mice model. The genes related to immune, cell structure, cell cycle, ion channel, signal transduction, protein synthesis and metabolism are involved in EAE pathogenesis. The results provide deeper insights into the mechanism of EAE and multiple sclerosis.
