Transcriptomics identified crucial candidate genes and pathways regulating early testicular development of drakes in the hypothalamic-pituitary-gonadal/thyroid axes.

ABSTRACT:

Background

The crosstalk between the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-thyroid (HPT) axes plays an important role in gonadal development. However, the mechanism by which these 2 axes regulate early testicular development in drakes remains largely unknown. Therefore, the aim of the present study was to compare the morphology, histology, and transcriptomics between the precocious puberty (PP) and delayed puberty (DP) Longyan Shan-ma drakes (Anas platyrhynchos) to preliminarily reveal the mechanisms regulating early testicular development.

Result

The histomorphological results showed that the colloid area and integrated optical density (IOD) of thyroid in PP group were significantly lower than those in DP group (P < 0.05), and the testis weight, te
