Acute heat stress induces differential gene expressions in the small yellow follicles of a broiler-type strain of Taiwan country chickens

ABSTRACT: To realize the gene expression in response to acute heat stress in chicken small yellow follicles, we have employed whole genome microarray expression profiling as we have employed whole genome microarray expression profiling as a tool to identify genes response to acute heat stress. Female B strain Taiwan country chickens were subjected to acute heat stress (38℃) for 2 h, and then exposed to 25℃, with small yellow follicles collected 0, 2, and 6 h after the cessation of heat stress, using non heat-stressed hens as a control group (n = 3 hens per group). Based on a chicken 44K oligo microarray, 69, 51, and 76 genes were upregulated and 58, 15, 56 genes were downregulated after heat treatment of H2R0, H2R2, and H2R6, respectively, using a cutoff value of two-fold or higher in the small yellow follicles of the heat-stressed chickens from those of the control chickens. Upregulation of heat shock protein 25, interleukin 6, metallopeptidase 1, and metalloproteinase 13, and downregulation of type II alpha 1 collagen, discoidin domain receptor tyrosine kinase 2, and Kruppel-like factor 2 were confirmed through quantitative real-time polymerase chain reaction (qRT-PCR).

Acute heat stress induces differential gene expressions in the testes of a broiler-type strain of Taiwan country chickens

Project description:To realize the gene expression in response to acute heat stress in chicken testis, we have employed whole genome microarray expression profiling as we have employed whole genome microarray expression profiling as a tool to identify genes response to acute heat stress. Male B strain Taiwan country chickens were subjected to acute heat stress (38M-bM-^DM-^C) for 4 h, and then exposed to 25M-bM-^DM-^C, with testes collected 0, 2, and 6 h after the cessation of heat stress, using non heat-stressed roosters as a control group (n = 3 roosters per group). Based on a chicken 44K oligo microarray, 163 genes significantly differed in the testes of the heat-stressed chickens from those of the control chickens. The mRNA expressions of upregulated genes, including HSP25, HSP90AA1, HSPA2, and LPAR2, and downregulated genes, including CDH5, CTNNA3, EHF, CIRBP, SLA, and NTF3, were confirmed through quantitative real-time polymerase chain reaction (qRT-PCR). Acute heat stress induced testicular gene experssion in B strain Taiwan country chicken was measured at 0, 2, and 6 h of recovery after 4 h of 38 degree acute heat stress.

The Jejunum Mucosa of Female Black-boned Chickens: Control vs. Heat-stressed Treatment

Project description:Transcriptional profiling of the jejunum mucosa with 1.5 fold-change reporter genes in comparing control black-boned chickens under normal temperature (NT) conditon with heat-stress treated black-boned chickens under high temperature (HT) condition. Goal was to determine the differentially expressed genes (DEGs) in co-family black-boned chickens exposure to heat stress based on global chicken gene expression. Two-condition experiment, HT vs. NT Treatment. Biological replicates: 3 control replicates, 3 heat stressed replicates.

Global comparative analysis on proteomes of chicken ovarian follicles before and after follicle selection

Project description:Ovarian follicle selection plays an important role in the reproduction of sexually mature hens, and this process can directly affect the growth and development of follicles until the final ovulation, thus affecting laying performance and fecundity of hens. In the laying hen ovary, one follicle from a cohort of 8-13 follicles of 6-8 mm in diameter is selected daily to enter the preovulatory hierarchy. In this study, we globally compared the proteomes of chicken ovarian follicles before and after follicle selection. A total of 5883 proteins were identified in the proteomes of chicken 6-8 mm prehierarchical follicles and 12-15 mm hierarchical follicles. 259 proteins are differentially expressed in 12-15 mm hierarchical follicle compared with prehierarchical follicle, of which 175 proteins are up-regulated and 84 proteins are down-regulated. The Gene Ontology enrichment of differentially expressed proteins revealed enriched GO terms for peptidase activity, acrosin binding for their molecular function and in the process of negative regulation of peptidase activity, and regulation of fertilization. The KEGG pathway analysis indicated that differentially expressed proteins were enriched for ribosome, lysine degradation, and endocytosis pathways. Nine differentially expressed proteins including vitellogenin-1 were validated with Parallel Reaction Monitoring (PRM) analysis, and their functions were discussed. This study provided a global proteomic view of the development of chicken ovarian follicles, which will serve as a foundation for understanding the molecular signatures and pathways of follicle selection in hens.
