Effect of Dietary Grain on Rumen Papillae Gene Expression in Holstein Dairy Cows

ABSTRACT: Four mature, non-lactating dairy cattle were transitioned from a high forage diet (HF; 0% grain) to a high grain diet (HG; 65% grain) that was fed for three weeks. Rumen papillae biopsies were performed during the HF baseline (week 0) and after the first (week 1) and third week (week 3) of the grain challenge to create a transcript profile for the the short and long-term adaption of the rumen epithelium during ruminal acidosis. Comparison between three weekly means (n=4 for each week, 12 arrays in total)

The molecular mechanisms underlying rumen epithelial adaption to high-grain (HG) diets are unknown. To gain insight into the metabolic mechanisms governing epithelial adaptation, mature nonlactating dairy cattle (n = 4) were transitioned from a high-forage diet (HF, 0% grain) to an HG diet (65% grain). After the cattle were fed the HG diet for 3 wk, they returned to the original HF diet, which they were fed for an additional 3 wk. Continuous ruminal pH, ruminal short chain fatty acids, and plasm ...[more]

Early concentrate starter introduction induces rumen epithelial parakeratosis by blocking keratinocyte differentiation with excessive ruminal butyrate accumulation

Project description:Rumen epithelial parakeratosis, a common disease in ruminants caused by abnormalities in the ruminal stratified squamous epithelial keratinization process, negatively impacts ruminant health and performance. While we still lack a comprehensive perception of the underlying mechanisms and the predisposing factors for this disorder.Here, we investigated rumen epithelial cell heterogeneity, differentiation trajectories, and cornification to clarify the rumen epithelial keratinization process

RNA-Seq data of ruminal epithelial tissue and 16S rRNA sequencing data of rumen digesta in goats infusion of three short-chain fatty acids [RNA-seq]

Project description:Emerging data has highlighted the importance of short-chain fatty acids (SCFAs), particularly butyrate, in regulating ruminal homeostasis in vivo isolated epithelial cells. However, little is known about other SCFAs like acetate or propionate, and the interaction between rumen microbes and epithelial immunity are rarely reported. Here, we firstly combined infusion of three SCFAs, to study their different roles in ruminal development, antioxidant capacity, barrier functions, and immunity, as well as cross-talk with ruminal microbiome (16S rRNA sequencing data of rumen digesta) and derived transcriptome (RNA-Seq) and metabolism using an in vivo goat model.

The SWI/SNF protein ATRX co-regulates pseudoautosomal genes that have translocated to autosomes in the mouse genome

Project description:Pseudoautosomal regions (PAR1 and PAR2) in eutherians retain homologous regions between the X and Y chromosomes that play a critical role in the obligatory X-Y crossover during male meiosis. Genes that reside in the PAR1 are exceptional in that they are rich in repetitive sequences and undergo a very high rate of recombination. Remarkably, murine PAR1 homologs have translocated to various autosomes, reflecting the complex recombination history during the evolution of the mammalian X chromosome. We now report that the SNF2-type chromatin remodeling protein ATRX controls the expression of eutherians ancestral PAR1 genes that have translocated to autosomes in the mouse. In addition, we have identified two potentially novel mouse PAR1 orthologs. We propose that the ancestral PAR1 genes share a common epigenetic environment that allows ATRX to control their expression. At E13.5, n = 3 biological replicates of littermate-matched wt/ko pairs. RNA from 2 forebrains were pooled to generate enough RNA for each sample. At P0.5, n = 4 biological replicates of littermate-matched wt/ko pairs (for pair #2 there is one wt and 2 Atrx-null samples (2A & 2B) and we count this as 2 pairs).

Effects of dietary forage and calf starter on ruminal pH and transcriptomic adaptation of the rumen epithelium in Holstein calves during the weaning transition

Project description:We assessed the transcriptomic adaptation of the calf rumen epithelium to changes in ruminal pH caused by feeding calf starter with and without forage during weaning transition. The calves were divided into a gorage provision group (HAY group, n = 3) and forage non-provision group (CON group, n = 4) 3 weeks after weaning.
