Comparison of gene expression between naturally occurring and diet-induced T2DM in cynomolgus monkeys
自发性与膳食诱发性食蟹猴2 型糖尿病其相关基因的表达比较

To explore pathological alteration of T2DM in cynomolgus monkeys, gene expression profiles of peripheral blood leukocytes from spontaneous and diet-induced T2DM models was analyzed using quantitative real-time PCR. Among 36 T2DM associated genes tested, 19 genes (including G6PC, CCR2B, CTLA4) displayed a similar expression pattern in both spontaneous and diet-induced T2DM models and were significantly up-regulated or down-regulated compared to controls. Interestingly, expression abundance of all up-regulated genes in the diet-induced T2DM was stronger, although not significantly, than spontaneous models, indicating diet-induced T2DM in monkeys should be a reliable research model for changes in gene expression. The characteristic gene expression pattern obtained here may be useful for the clinical diagnosis of T2DM.
