Project description:Purpose: Aim of this study was to determine the miRNAs associated with average daily gain in Kangal Akkaraman lambs. Depending on the average daily gain, two groups were formed as low average daily gain (LDG) and high average daily gain (HDG). Methods: Peripheral blood mononuclear cells (pbmc) were separated from blood samples obtained from lambs and RNA was isolated with TRI Reagent (Sigma). Isolated total RNAs from LDG (n = 17) and HDG (n = 21) groups were pooled. miRNA libraries (LDG and HDG groups) were prepared with NEBNext® Multiplex Small RNA Library Prep Set for Illumina® (NEB, USA.) and sequenced with Illumina Novaseq. Readings were mapped with the Bowtie program using the Oar_v3.1 sheep reference genome. Differential expression analysis of the two groups was performed using the DESeq R package (1.8.3). Results: Using an optimized data analysis workflow, we mapped about 18 million sequence reads in HDG and 21 million sequence reads n LDG samples to the ovis aries genome (oar_v3.1). In total, 129 known miRNAs were identified, 134 novel miRNAs were predicted, and 40 differentially expressed miRNAs were found between the groups. Conclusions: Our study represents the first detailed analysis of Kangal type Akkaraman sheep PBMC miRNAs with RNA-seq technology. The obtained sequence reads would provide data for futher breeding studies related to average daily gain in Kangal Akkraman sheep.

Project description:The objective of this experiment was to use transcriptional profiling of skeletal muscle and adipose tissue to develop a better understanding of the metabolic basis for poor weaned-pig transition. A total of 1,054 pigs were reared in commercial conditions and weighed at birth, weaning, and 3 weeks post- weaning. Transition average daily gain (tADG) was calculated as the average daily gain for the 3-week period post-weaning. Nine pigs from each of the lowest 10th percentile (low tADG) and the 60th-70th percentile (high tADG) were harvested at 3 weeks post-weaning. Differential expression analysis was conduced in both tissues using RNA-Seq methodology

Project description:Increased susceptibility of circadian clock mutant mice to metabolic diseases has led to the understanding that a molecular circadian clock is necessary for metabolic homeostasis. Circadian clock produces a daily rhythm in activity-rest and an associated rhythm in feeding-fasting. Feeding-fasting driven programs and cell autonomous circadian oscillator act synergistically in the liver to orchestrate daily rhythm in metabolism. However, an imposed feeding-fasting rhythm, as in time-restricted feeding, can drive some rhythm in liver gene expression in clock mutant mice. We tested if TRF alone, in the absence of a circadian clock in the liver or in the whole animal can prevent obesity and metabolic syndrome. Mice lacking the clock component Bmal1 in the liver, Rev-erb alpha/beta in the liver or cry1-/-;cry2-/- (CDKO) mice rapidly gain weight and show genotype specific increased susceptibility to dyslipidemia, hypercholesterolemia and glucose intolerance under ad lib fed condition. However, when the mice were fed the same diet under time-restricted feeding regimen that imposed 10 h feeding during the night, they were protected from weight gain and other metabolic diseases. Transcriptome and metabolome analyses of the liver from there mutant mice showed TRF reduces de novo lipogenesis, increased beta-oxidation independent of a circadian clock. TRF also enhanced cellular defense to metabolic stress. These results suggest a major function of the circadian clock in metabolic homeostasis is to sustain a daily rhythm in feeding and fasting. The feeding-fasting cycle orchestrates a balance between nutrient stress and cellular response to maintain homeostasis.
