Project description:Dietary supplementation with fish-oil modulates ruminant milk composition towards a healthier fatty acid profile for consumers, but it also causes milk fat depression (MFD). Because the dairy goat industry is mainly oriented towards cheese manufacturing, MFD can elicit economic losses. There is large individual variation in animal susceptibility with goats more (RESPO+) or less (RESPO−) responsive to diet-induced MFD. Thus, we used RNA-Seq to examine gene expression profiles in mammary cells to elucidate mechanisms underlying MFD in goats and individual variation in the extent of diet-induced MFD.

Project description:The mammary gland redeveloped to the pre-pregnancy state during involution, which shows that the mammary cells have the characteristics of remodeling. The rapidity and degree of mammary gland involution are different between mice and dairy livestock (dairy cows and dairy goats). However, the molecular genetic mechanism of involution and remodeling of goat mammary gland has not yet been clarified. Therefore, this study carried out the RNA-sequencing of nonlactating mammary gland tissue of dairy goats in order to reveal the transcriptome characteristics of nonlactating mammary tissues and clarify the molecular genetic mechanism of mammary cell involution and remodeling.

Project description:To evaluate the long-term growth potential of BCR-ABL-transduced primitive human hematopoietic cells, lin- cord blood cells containing an MSCV-BCR-ABL-IRES-GFP (BCR-ABL) or control-GFP transgene (MIG) were injected IP into fetal goats at 45-55 days of gestation. Six transplant goats were born alive. One was examined three weeks after birth and showed GFP+ cells in the blood, bone marrow (BM), liver, kidney, lung, heart, and both skeletal and smooth muscle. FISH analysis also showed the liver of this goat contained BCR-ABL-GFP transgenic cells. The remaining five goats appear normal although, in some, the WBC count is elevated 3- to 5-fold. GFP+ cells, including cells identifiable by FACS as human CD34+ cells, have been detected in the blood of all these goats. The presence of BCR-ABL-GFP transgenic cells in the BM and liver was confirmed by FISH analysis, and quantitative real-time PCR analysis of genomic DNA isolated from unpurified BM cells obtained from three of the transplant goats demonstrated 3-5Ã104 copies of the transgene per microgram of DNA. Microarray transcript profiling was performed on blood and liver tissues of normal goats, BCR-ABL chimeric goats, MIG chimeric goats, and normal human samples. RNA for human genes was detected in goats transplanted with cord blood cells but not in normal goats, and the RNA abundance of some genes in BCR-ABL chimeric goat blood was similar to or greater than levels observed in MIG goat blood or normal human samples. Quantitative RT-PCR confirmed the differential expression of several genes in goats carrying the BCR-ABL vs. control transgene. These results demonstrate long-term engraftment but slow expansion in a large animal model of primitive human hematopoietic cells transduced with a BCR-ABL fusion gene and transplanted in utero. This novel xenotransplant goat model should be useful for analyzing the initial phases of development of human CML and for assessing new therapies with potential long-term benefits. Experiment Overall Design: Total RNA was extracted from liver (L) and blood (B) samples of normal goats (ng), humans (hu), chimeric goats engrafted with human cord blood stem cells containing control (mig) vector, and chimeric goats engrafted with CML (bcrabl) vector. RNA samples were profiled on Affymetrix human U133A GeneChips and examined for differentially expressed genes in CML vs control goats, filtering for signals significantly above background levels observed in normal goat to select for specific human gene expression.

Project description:In the present study, RNA-seq technique was used to compare the expression profiles of circRNAs from goat endometrium samples at gestational day 5 (pre-receptive endometrium, PE) and day 15 (receptive endometrium, RE). A total of 21,813 circRNAs were identified in goat endometrium, of which only 31.22% (6,810) circRNAs were co-expressed at both stages, and 5,925 circRNAs were identified specifically in RE and 9,078 in PE, suggesting high stage specificity in the circRNAs in dairy goats. Further analysis found that there were 334 DECs (differentially expressed circRNAs) in RE compared to PE (P< 0.05), and circRNA8077 was up-regulated with the highest FPKM value in RE. It was noteworthy that half of the up-regulated circRNAs with top 10 highest FPKM value in RE were come from CRIM1. Moreover, GO and KEGG analysis of the hgDEGs (hosting genes of DECs) revealed some circRNAs, genes and pathways that may involve in the formation of the receptive endometrium in dairy goats. In a word, our data provided an endometrium circRNA expression atlas related to the biology of the goat receptive endometrium during embryo implantation, and the results suggested that a subset of circRNAs might involve in the processes of the formation and development of endometrial receptivity.

Project description:We sequenced the miRNAs in the liver tissues of goats to further enrich and elucidate the miRNA expression profile in their physiological cycle. The liver tissues were procured at 5-time points from the Laiwu black goats of 1 day, 2 weeks, 4 weeks, 8 weeks, and 12 weeks of age, respectively with 5 goats per time point, for a total of 25 goats. This study identified 1255 miRNAs.

Project description:Cattle are often fed high concentrate diets to increase energy intake and improve overall animal performance. Such diets also cause changes in fermentation patterns and epithelial function. However, the molecular mechanisms involved in regulating epithelial function for cattle fed high concentrate diets have not been elucidated. In this study, we aimed to gain a broad overview of the involved molecular mechanisms by detecting differentially expressed genes (DEG) in rumen tissue from dairy cows fed a low concentrate (LC; 8%) compared to a high concentrate (HC; 64%) diet using a bovine-specific microarray platform containing 16,846 unique gene loci and 5,943 ESTs from the bovine genome. Feeding the HC diet increased the total volatile fatty acid concentration and markedly reduced ruminal pH, suggesting that the dietary treatments used did induce changes in ruminal fermentation. In response to changes in the ruminal environment, a total of 5,200 elements were detected as DEG in ruminal tissue with >1.5-fold expression change (P < 0.05) for cows fed HC relative to LC. Of the 5,200 DEG, 2,233 and 2,967 were up- and down-regulated, respectively. The GENECODIS analysis elucidated that relationships among the DEG represented 19 annotations characterized with GO molecular function and KEGG pathways with 26 DEG identified in multiple annotations such as calcium signaling and gap junction pathways. Among those DEG that were identified numerous times, catalytic subunit of cAMP-dependent protein kinase (PRKACB) was down-regulated in ruminal tissue from cows fed HC, suggesting that this gene may have important roles including regulation of cell proliferation and differentiation, and intracellular pH regulation. Two-condition experiment, High concentrate vs. Low concentrate diets. Biological replicates: 5 high concentrate fed, 5 low concentrate, independently grown and harvested. Two replicates per array.
