Project description:Comprehensive analyses of tissues at single-cell level will benefit our understanding of genetic bases for complex traits. Here we present an initial effort of single-cell transcriptomic analyses of cattle ruminal epithelial cells during the rumen development. We obtained 5064 and 1372 cells from Holstein ruminal epithelial cells before and after weaning, respectively. We reported 6 cell types across their temporal and spatial distributions, which were partially correlated with rumen epithelium layer’s structures and functions. We also reported a distinct sets of cell markers for these cell types, for example, CRA1, HMMR, MKI67, and EZH2 for the dividing epithelial cells and the TGFB pathway and the keratin gene family for keratinized epithelial cells. Our proposed a cell lineage model may contribute to the understanding of cattle rumen epithelial proliferation and development.

Project description:Creatine pyruvate (CrPyr) is a new multifunctional nutrient that can provide both pyruvate and creatine. It has been shown to relieve the heat stress of beef cattle by improving antioxidant activity and rumen microbial protein synthesis, but the mechanism of CrPyr influencing rumen fermentation remains unclear. This study aimed to use metaproteomics technologies to investigate the bacterial protein function in rumen fluid samples taken from heat-stressed beef cattle treated with or without 60 g/d CrPyr.

Project description:Hanwoo cattle are a Korean breed renowned for their cultural significance and high-quality beef, characterized by low cholesterol and high unsaturated fat ratio. Growth is divided into a growing phase focused on development and a fattening phase for marbling. Proper feed management, considering genetic and environmental factors, is vital for maximizing growth potential. The rumen plays a crucial role in digestion and gene expression regulation, with rumen fermentation being central to nutrient absorption and cattle health. In this study, we conduct transcriptome analysis of the rumen at eight timepoints. Our goal is to identify genetic factors that influence the growth of Hanwoo steers to enhance our understanding of the rumen’s functions and roles during their growth. In this RNA-sequencing analysis of Hanwoo steer rumen, differential gene expression was examined over eight timepoints, highlighting significant genetic changes, particularly between 12 and 26 months. Weighted gene co-expression network analysis identified and organized as three modules: turquoise, blue, and yellow. The turquoise module, linked to immune response, showed down-regulation in genes at 30 months. The blue module, associated with steroid metabolism, was notably up-regulated at 26 months. The yellow module’s genes showed a consistent increase in expression with growth. These modules and their functional annotations provide a deeper understanding of the biological processes during Hanwoo growth, highlighting the intricate relationship between gene expression and cattle development. The growth stages of Hanwoo steers were explored in our investigation utilizing rumen transcriptome data. The rumen plays critical role in their development, particularly during the growing and fattening phases. Proper feed management, considering the rumen’s function, is essential for optimal growth. Transcriptome analysis helps identify genes associated with growth and provides insights for cattle breeding and management practices. Understanding the complex connection between gene expression and Hanwoo development is essential for maximizing productivity and health.

Project description:In this study, we generated genome-wide data sets for four histone modifications, including H3K9ac, H3K27ac, RNA pol II, H3K9me3,, which were collected from rumen tissues before and after Butyrate treatment. By combining other types of data sets collected in Rumen Epithelial Primary Cells (REPC) , inclduing four histone codes, CTCF, DNA accessibility, DNA methylation, and RNA-seq, we established and validated the first global map of regulatory elements (15 chromatin states) and defined their coordinated activities in cattle. We, for the first time, were able to establish the correlation among nutritional elements, chromatin states, gene activities, and phenotypic outcomes.
