Project description: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).

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.

Project description:The aim of the present study was to investigated the difference of Nrf2-regulated genes in livers between normal and heat-stressed chickens. The CUT&Tag and high-throughput sequencing technologies were used in this experiment. Results showed that 13171838- 15417444 clean reads were obtained in this study. These data suggested that there were many Nrf2- regulated genes in the liver of heat-stressed chicken.

Project description:Climate change and disease have large negative impacts on poultry production, but little is known about the interactions of responses to these stressors in chickens. Fayoumi (heat and disease resistant) and broiler (heat and disease susceptible) chicken lines were stimulated at 22 days of age, using a 2x2x2 factorial design including: breed (Fayoumi or broiler), inflammatory stimulus [lipopolysaccharide (LPS) or saline], and temperature (35°C or 25°C). Transcriptional changes in spleens were analyzed using RNA-sequencing on the Illumina HiSeq 2500. Thirty-two individual cDNA libraries were sequenced (four per treatment) and an average of 22 million reads were generated per library. Stimulation with LPS induced more differentially expressed genes (DEG, log2 fold change ≥ 2 and FDR ≤ 0.05) in the broiler (N=283) than the Fayoumi (N=85), whereas heat treatment resulted in fewer DEG in broiler (N=22) compared to Fayoumi (N=107). The double stimulus of LPS+heat induced the largest numbers of changes in gene expression, for which broiler had 567 DEG and Fayoumi had 1471 DEG of which 399 were shared between breeds. Further analysis of DEG revealed pathways impacted by these stressors such as Remodelling of Epithelial Adherens Junctions due to heat stress, Granulocyte Adhesion and Diapedesis due to LPS, and Hepatic Fibrosis/Hepatic Stellate Cell Activation due to LPS+heat. The genes and pathways identified provide deeper understanding of the response to the applied stressors and may serve as biomarkers for genetic selection for heat and disease tolerant chickens.
