Project description:The gut microbiota exerts profound influence on poultry immunity and metabolism through mechanisms that yet need to be elucidated. Here we used conventional and germ-free chickens to explore the influence of the gut microbiota on transcriptomic along the gut-lung axis in poultry. Our results demonstrated a differential regulation of genes associated with innate immunity and metabolism in the spleen of germ-free birds.

Project description:The gut of chicken is mostly colonised with Campylobacter jejuni and with 100 fold less C. coli. The competitive ability of C. coli OR12 over C. jejuni OR1 has been examined in experimental broiler chickens following the observation that C. coli replaced an established C. jejuni intestinal colonisation within commercial chicken flocks reared outdoors (El-Shibiny, A., Connerton, P.L., Connerton, I.F., 2005. Enumeration and diversity of campylobacters and bacteriophages isolated during the rearing cycles of free-range and organic chickens. Applied Environmental Microbiology. 71, 1259-1266).

Project description:Asymmetrical gonadal development is an intriguing phenomenon observed in the majority of female birds. In chickens, the left gonad of female embryos develops into a functional ovary, while the right gonad undergoes degeneration during embryogenesis. This sexually dimorphic trait is primarily induced by the spatial differential expression of the PITX2 gene. However, a comprehensive understanding of the transcriptional profile of the developing gonads during asymmetric development is still lacking. To elucidate the molecular mechanism of asymmetric gonadal development in chickens, we compared the transcriptomes between left and right gonads of female chickens using bulk- and single cell (sc) -RNA sequencing (RNA-seq) approaches. Our bulk RNA-seq analysis of the female chicken gonads at E5 (HH26), E6.5 (HH30), E8 (HH34), and E9.5 (HH36) revealed significant differential gene expression between the left and right female chicken gonads, particularly in signaling pathways, cell cycle, and metabolic processes. Moreover, scRNA-seq analysis revealed that coelomic epithelial, interstitial, and pre-granulosa cells of the left gonads share a highly proliferative status, contributing to the asymmetric gonadal cell proliferation, which may be regulated by the TGFβ signaling pathway. Our findings demonstrate that dynamic cell-type-specific transcriptional profiles during embryogenesis play a vital role in the asymmetric gonadal development of female chickens.

Project description:Carnosine is a bioactive food component with several potential health benefits for humans due to its physiological functions. Dietary supplementation with β-alanine or L-histidine can increase the carnosine content of skeletal muscles in chickens. Dietary supplementation with β-alanine or L-histidine has produced a slow-growing chicken variety with high carnosine content in the breast meat; however, the supplementation with L-histidine alone softens the meat toughness, which may affect consumers’ willingness to buy the meat. Gene expression is a key factor that influences meat quality. Understanding the molecular mechanisms that affect carnosine content and meat toughness would allow the production of more value-added slow-growing chickens. We compared global gene expression in chicken breast muscles with differing carnosine contents and meat toughness produced through dietary supplementation with β-alanine or L-histidine. We identified differentially expressed genes involved in regulating myosin, collagen, intramuscular fat, and calpain—factors that may affect meat tenderness. Pathway enrichment analysis indicated that the insulin-related and adipocytokine signaling pathways were altered by dietary supplementation with β-alanine or L-histidine. These data will be useful for future studies on carnosine content and meat toughness in slow-growing chickens.
