Abstract

Chronic social stress caused by repeated negative experiences in agonistic interactions induces depressive-like behavior in male mice. The aim of this study was to investigate expression changes of genes encoding proteins involved in the metabolism, receptor sensing, and transport of catecholamines, opioids, glutamate, and GABA under the influence of chronic social stress. Hypothalamus samples were analyzed using high-throughput RNA sequencing. It was shown that in the depressed animals, the expression of catecholaminergic genes Adra1b, Adrbk1, Comtd1, Ppp1r1b, Sncb, Sncg, and Th is increased, while the expression of genes Maoa and Maob is reduced. The expression of opioidergic and cannabinoidergic genes Pdyn, Penk, Pomc, Pnoc, Ogfr, and Faah was found to be upregulated, while that of genes Oprk1, Opcml, Ogfrl1, and Cnr1 was downregulated. The expression of glutamatergic genes Grik3, Grik4, Grik5, Grin1, Grm2, and Grm4 was increased, while the expression of Gria3, Grik1, Grik2, Grin2a, Grin3a, Grm5, Grm8, and Gad2 was reduced. The expression of GABAergic genes Gabre, Gabbr2, and Slc6a11 was higher, while the expression of Gabra1, Gabra2, Gabra3, Gabrb2, Gabrb3, Gabrg1, Gabrg2, and Slc6a13 was lower in the depressed animals. The results suggest that the products of genes that interact with other neurotransmitter systems (Th, Gad2, Gabra1, Gabrg2, Grin1, and Pdyn) may be of interest as potential targets for the pharmacotherapy of consequences of chronic social stress.

慢性社会压力对雄性小鼠下丘脑神经递质系统相关基因表达的影响
摘要 在激动互动中反复出现的负面经历所导致的慢性社会应激会诱发雄性小鼠的抑郁样行为。本研究旨在探讨在慢性社会应激影响下,编码儿茶酚胺、阿片类、谷氨酸和 GABA 代谢、受体感应和转运相关蛋白的基因的表达变化。研究人员利用高通量 RNA 测序技术对下丘脑样本进行了分析。结果表明,在抑郁动物中,儿茶酚胺能基因Adra1b、Adrbk1、Comtd1、Ppp1r1b、Sncb、Sncg和Th的表达量增加,而基因Maoa和Maob的表达量减少。发现阿片能和大麻能基因 Pdyn、Penk、Pomc、Pnoc、Ogfr 和 Faah 的表达上调,而基因 Oprk1、Opcml、Ogfrl1 和 Cnr1 的表达下调。谷氨酸能基因 Grik3、Grik4、Grik5、Grin1、Grm2 和 Grm4 的表达增加,而 Gria3、Grik1、Grik2、Grin2a、Grin3a、Grm5、Grm8 和 Gad2 的表达减少。抑郁动物的 GABA 能基因 Gabre、Gabbr2 和 Slc6a11 的表达量较高,而 Gabra1、Gabra2、Gabra3、Gabrb2、Gabrb3、Gabrg1、Gabrg2 和 Slc6a13 的表达量较低。结果表明,与其他神经递质系统相互作用的基因(Th、Gad2、Gabra1、Gabrg2、Grin1和Pdyn)的产物可能是慢性社会应激后果药物治疗的潜在靶点。
