Mastication stimuli enhance the learning ability of weaning-stage rats

Using DNA microarray analysis, differentially expressed genes were enriched in functional terms related to dendrite growth and included the Igf2, RhoA, and Rho GEF genes, most of which were upregulated in the chow diet group.采用DNA微阵列（DNA microarray）分析技术，差异表达基因在与树突生长相关的功能条目中显著富集，涵盖Igf2、RhoA及Rho GEF基因，其中大多数基因在常规饲料组中呈上调表达。
