(Submitter supplied) Our group has developed an extra-uterine environment for newborn development (EXTEND) using an ovine model, that aims to mimic the womb to improve short and long-term health outcomes associated with prematurity. This study’s objective was to determine the histologic and transcriptomic consequences of EXTEND on the brain. Histology and RNA-sequencing was conducted on brain tissue from three cohorts of lambs: control pre-term (106-107 days), control late pre-term (127 days), and experimental lambs who were born pre-term and supported on EXTEND until late pre-term age (125-128 days). more...

(Submitter supplied) the hypothalamus tissues of high-reproduction small-tailed Han sheep and low-reproduction Wadi sheep were collected, and full-length transcriptome sequencing by Oxford Nanopore Technologies (ONT) was performed to explore the key functional genes associated with sheep fecundity. The differentially expressed genes (DEGs) were screened and enriched using DESeq2 software through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG).

(Submitter supplied) Feed restriction during the early life of ewe lambs (F0) triggers the transfer of epigenetic marks to the next generation, thus impairing the reproductive performance of F1. However, the effects of this factor on milk production and composition, including its abundance in regulatory miRNA (many of which are contained in exosomes, small vesicles of endocytic origin that play a role in the modulation of immune response of the offspring), has not been tested so far. more...

(Submitter supplied) In the current study, five late gestation multiparous ewes were restricted to a 30% feeding level to create a model of malnutrition, while five other ewes were fed normally as controls. All ewes were sacrificed and jejunal and ileal samples were collected for transcriptome sequencing to study metabolic changes.

(Submitter supplied) The preservation of locally endangered breeds is essential for ecosystem services that affect both society and the environment. Reproductive fitness becomes a crucial consideration in this regard. MicroRNAs (miRNAs) are small noncoding RNA molecules with a key role in post-transcriptional regulation. They usually act in tissues, where they are produced, but when released in extracellular fluid, they are termed circulating miRNAs (c-miRNAs). more...

(Submitter supplied) The fat tail of sheep is an important organ that has evolved to adapt to extreme environmental conditions. Mesenchyme homeobox 2 (MEOX2) can inhibit adipogenic differentiation of stromal vascular fractions (SVFs) isolated from ovine tail adipose tissue. However, the underlying mechanism through which MEOX2 regulates ovine adipogenesis remains unclear. Therefore, this study aims to employ RNA sequencing (RNA-seq) to explore the downstream genes regulated by MEOX2 during the adipogenic differentiation of ovine SVFs. more...

(Submitter supplied) [Background] Antenatal steroid (ACS) therapy conveys lifesaving benefits to the preterm fetus. However, current treatments are associated with increased risk of growth, endocrine, and neurodevelopmental abnormalities. [Objectives] To inform ACS therapy optimisation we used a sheep model of pregnancy to test whether adverse fetal brain effects were independent of respiratory benefit and ACS pharmacokinetics. more...

(Submitter supplied) Improving the fertility of sheep is an important goal in sheep breeding as it greatly increases the productivity. Dolang sheep is a typical representative breed of lamb in Xinjiang and is the main local sheep breed and meat source in the region. To explore the genes associated with the initiation of puberty in Dolang sheep, the hypothalamic tissues of Dolang sheep prepubertal, pubertal, and postpubertal periods were collected for RNA-seq analysis on the Illumina platform.

(Submitter supplied) Zygotic genome activation (ZGA) is essential for early embryo development. Here, we reported that ZGA is initiated at 16-cell stage in sheep, as extensive alterations in gene expression and DNA methylation patterns, along with elevated levels of RNA polymerase II and developmental arrest was found at the 16-cell embryos. To uncover the sophisticated RNA metabolism during ZGA, we conducted weighted gene co-expression network analysis and identified 1957 critical maternal genes. more...

(Submitter supplied) In the Ross procedure, a patient's pulmonary valve is transplanted into aortic position. Reoperation is needed in many cases due to failure through dilatation of the pulmonary autograft. To further understand the failure mechanisms, gene expression profiling of the autograft tissue was performed and compared to control aortic and pulmonary sinus tissue though bulk RNA-seq. Notable results include the upregulation of inflammatory pathways and genes coding for proteins important for the structural integrity of the tissue, such as extracellular matrix proteins, collagenases and elastases.

(Submitter supplied) Background: In mammals, female fertility is determined by the outcome of follicular development (ovulation or atresia). Follicular atresia is a complex physiological process that results in the degeneration of oocytes from the ovary. However, the molecular mechanisms of oocyte degeneration and key protein markers of follicular atresia remain unclear. In this study, we explored the complex transcriptional regulatory mechanisms and protein profiles in oocytes and follicular fluid in atretic follicle stages using single-cell RNA sequencing and tandem mass tag proteomics. more...
