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:In order to reveal the changes of microRNA spectrum in hypothalamus tissues of goats from birth to sexual maturity, smallRNA sequencing was performed on hypothalamus tissues of Jining grey goats at 4 developmental stages after birth. Twenty libraries from 4 different developmental stages (5 goats per stage) were successfully constructed and the corresponding miRNA expression profiles were obtained.
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:Laiwu black goat kid liver mRNA expression profile were sequenced with novaSeq 6000. 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.
Project description:As goats are important domestic animals, the regulation of germline and gonadal somatic cells in goats during the mitotic quiescence phase has not been investigated previously. In this study, we employed single-cell RNA sequencing to identify transcriptional signatures of major prospermatogonia and somatic cell types of the testes in goats from E85, E105 and E125.

Project description:Robust human-goat chimerism was achieved by transplanting human CD34+Lin- cord blood cells into fetal goats. We observed a broad distribution of GFP-marked human cells in non-hematopoietic organs including kidney, muscle, lung, and heart of transplant goats. Various marker techniques indicated that human genes were expressed in chimeric livers and blood.
Project description:We identified the mRNA and long non-coding RNA expression profiles of 100-day fetal skin between the dark and normal (white) skin in two breeds of goats using the deep RNA sequencing method. Case-control. Briefly, the 100-day fetal skin sampled from the normal and hyperpigmentated goats for deep sequencing, in triplicate for each breed, using Illumina
Project description:We deep sequenced and analyzed circRNA using deep RNA sequencing (RNA-seq) in pre-ovulatory follicle samples of Macheng black goats and Boer goats. We analyzed the RNA-seq data with 301 million reads and 288 million reads, and reveal the expression profiles of circRNAs and predicted 13,950 circRNAs. 827 circRNA host genes, mostly related to transferase activity and metabolic process. Twenty-four circRNAs were upregulated and 13 were downregulated in the pre-ovulatory follicles of the Boer group compared to their expression in the Macheng group.
