Project description:Imputed whole-genome sequencing data of 669 German Black Pied bulls (DSN)
Project description:We found four circulating miRNAs showing high levels in plasma of pregnant Japanese Black cows. Since these miRNAs are less affected by the measurement system due to hemolysis, it was suggested that they may be used as markers for early pregnancy diagnosis in cattle.
Project description:To assess how different levels of stress exposure affect gene regulation mechanisms in cattle, we investigated gene expression in 13 Italian Red Pied dairy cows falling in the high- and low-variant tails of the distribution of milk cortisol concentration (MC), a neuroendocrine biomarker of stress in dairy cows, measured in 126 animals belonging to the same farm in the framework of the Gen2Phen Italian project. The ‘low-’ and ‘high-cortisol’ groups of animals had MC<370 pg/ml and>810 pg/ml, respectively. To date, 13 animals (6 low- and 7 high-MC) have been sequenced. We detected significant fold differences in the expression of 324 genes. KEGG and Gene Ontology (GO) pathway analyses indicated that these genes were mainly involved in immune regulatory pathways, glucocorticoids metabolism and nervous system functions.
Project description:A heat stress (HS) cattle research design was implemented to study HS effects on the three different “omics features” methylations, gene expressions and metabolic pattern from a direct perspective in pregnant cows and from an indirect time-lagged intergenerational perspective in offspring (the respective F1 and as F1 offspring before calving). In this regard, German Holstein dairy cows and their calves were blood sampled for DNA and RNA extraction and for metabolic phenotyping, and allocated to HS and respective control groups (the cows (dams) as well as their calves) according to a temperature-humidity threshold of 60.
Project description:The coat color of mammals is determined by the melanogenesis pathway, which is responsible for maintaining the balance between black-brown eumelanin and yellow-reddish phaeomelanin. It is also believed that the color of the bovine nose is regulated in a similar manner; however, the molecular mechanism underlying pigment deposition in the black nose has yet to be elucidated. The aim of the present study was to identify melanogenesis-associated genes that are differentially expressed in the black vs. yellow nose of native Korean cows. Experiment, Yellow nose vs. Black nose HanWoo
Project description:To investigate the impact of maternal nutrient restriction on skleletal muscle gene expression, we profiled gene expression in longissimus muscle of Japanese Black fetal calves in high and low nutrient condition of pregnant maternal cows .
