Identification of nucleotide polymorphisms in the key promoter region of chicken annexins A2 gene associatied with egg laying traits.

Annexin A2 () is a member of the A subfamily of a multifunctional calcium dependent membrane phospholipid binding protein family. The mRNA expression of is consistent with ovary function and egg laying in chickens. In this study, six nucleotide polymorphisms in the key promoter region of chicken gene (-2861bp to -1394bp), i.

Characterization of microRNA Profiles in -Infected Rabbits and Identification of miR-29-5p as a Regulator of Antibacterial Immune Response.

is the pathogenic agent for a variety of severe diseases in livestock, including rabbits. MicroRNAs (miRNAs) participate in the immune response to the pathogen. Distinct miRNA expression patterns were explored in rabbit lung by small-RNA deep sequencing to assess dysregulated miRNAs during infection.

Integrated transcriptomic analysis on small yellow follicles reveals that sosondowah ankyrin repeat domain family member A inhibits chicken follicle selection.

Objective: Follicle selection is an important process in chicken egg laying. Among several small yellow (SY) follicles, the one exhibiting the highest expression of follicle stimulation hormone receptor (FSHR) will be selected to become a hierarchal follicle. The role of lncRNA, miRNA and other non-coding RNA in chicken follicle selection is unclear.

Benefit of Dietary Supplementation with Bacillus subtilis BYS2 on Growth Performance, Immune Response, and Disease Resistance of Broilers.

A strain of Bacillus subtilis (B. subtilis) BYS2 was previously isolated from Mount Tai, which is located in Tai'an City in the Shandong Province of China. The strain was then stored in the Environmental Microbiology Laboratory at Shandong Agricultural University.

Variants of pri-miR-26a-5p polymorphisms are associated with values for chicken egg production variables and affects abundance of mature miRNA.

MicroRNAs (miRNAs) are a class of endogenous non-coding RNAs that have an important role in post-transcriptional regulation. Previous analysis of the chicken ovary transcriptome indicated there was a differential abundance of miR-26a-5p in sexually mature and immature hens. In this study, ten single nucleotide polymorphism (SNP) sites in miR-26a-5p primary transcripts (pri-miR-26a-5p) were identified using Sanger sequencing on PCR products in three chicken breeds, among which, the rs316365438(C > T)SNP was associated with age at first egg (AFE) and total number of eggs at 32 weeks (E32).
