The Effect of Kisspeptin Preparations on the Expression of CRH, GRH, GNRHR1, and OXT Genes in the Brain of Danio rerio after Social Isolation
摘要
The effect of kisspeptin preparation on the expression of the genes of hormonal regulation of sexual behavior in Danio rerio fish was studied after the effect of social isolation. For this, fish were placed in individual containers for 48 h to model the conditions of social isolation, after which kisspeptin was administered, and they were again placed in the conditions of social isolation for 1 day. It was established that changes in the expression of the crh, grh, gnrhr1, and oxt genes occurred in the fish brain after social isolation upon administration of kisspeptin peptide. It is interesting that the expression of these genes changed both under isolation conditions and during subsequent effect of kisspeptin, which indicates possible mechanisms of regulating stress and behavioral responses through hormonal systems.
