Feather follicle development is essential for the phenotypic characteristics and economic value of domesticated geese. In this study, we conducted a comparative transcriptomic analysis to explore the breed-specific molecular mechanisms involved in feather follicle development in Zhedong white goose (Anser cygnoides) and Hungarian white goose (Anser anser) at five critical embryonic stages (E10, E13, E18, E23, and E28). A total of 19,622 differentially expressed genes (DEGs) were identified in geese feather follicles across the comparison groups, with significant enrichment in pathways associated with neuroactive ligand-receptor interaction, melanogenesis, tyrosine metabolism, metabolic pathways, PPAR, p53, VEGF, and Hedgehog signaling pathways.

Despite their importance, genes, proteins, and pathways regulating goose testicular development are poorly understood. This study employed integrative transcriptomic and proteomic analysis methods to identify critical regulators of testicular development in geese across three reproductive periods.

The testis is the main organ responsible for sperm production, and the egg-laying cycle in geese is a complex physiological process that demands precise orchestration of hormonal cues and cellular events within the testes, however, the seasonal changes in the transcriptomic and proteomic profiles of goose testicles remain unclear. To explore various aspects of the mechanisms of the seasonal cyclicity of testicles in different goose breeds, in this study, we used an integrative transcriptomic and proteomic approach to screen the key genes and proteins in the testes of 2 goose males, the Hungarian white goose and the Wanxi white goose, at 3 different periods of the laying cycle: beginning of laying cycle (BLC), peak of laying cycle (PLC), and end of laying cycle (ELC).

Despite its importance in the poultry industry, no available genome assembly information has been published. This study aimed to present Chromosome-level and functional genome sequencing of the Hungarian White Goose.

Therefore, understanding and regulating the development of skin and feather follicles during embryogenesis is critical for avian biology and the poultry industry. MicroRNAs are known to play an important role in controlling gene expression during skin and feather follicle development.

Dermal fibroblasts are required for structural integrity of the skin and for feather follicle development. How FOXO3 affects feather follicle development as skin tissues change during goose embryo (Anser cygnoides) development and growth is not well understood.

As a classic method to evaluate spatial learning and memory, the Morris water maze is widely applied to study the cognitive deficits in rodent AD models. However, the assay procedure is relatively complicated and requires a properly equipped environment.
