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.

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 lungs of germ-free birds.

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:Here we tracked the development of the caecal microbiota in conventional White leghorn chickens of the PA2 line kept in isolators for 7 14 or 21 days using 16S sequencing.
Project description:Analysis of breast cancer survivors' gut microbiota after lifestyle intervention, during the COVID-19 lockdown, by 16S sequencing of fecal samples.
Project description:H5N1 subtype highly pathogenic avian influenza virus has been spreading to Asia, Eurasia and African coutries. An original or six of recombinant H5N1 subtype influenza viruses with varying survivability were infected to chickens for elucidating genes correlated with pathogenicity.
Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds.
Project description:Gut microbiota were assessed in 540 colonoscopy-screened adults by 16S rRNA gene sequencing of stool samples. Investigators compared gut microbiota diversity, overall composition, and normalized taxon abundance among these groups.
