Pregnancy loss in cattle can be caused by inadequate development and differentiation of the placenta. However, the cellular and molecular mechanisms regulating bovine placenta development and, particularly, trophoblast differentiation are not well understood. Recent single-cell RNA-seq analyses revealed dynamic changes in cell populations and gene expression patterns during bovine placental development. Here, the chromatin accessibility landscape across diverse cell populations was determined in the developing (day 40) and mature (day 170) bovine placenta using the 10X Genomics multiome (snRNA-seq and snATAC-seq) platform. Analyses revealed distinct trophoblast, mesenchyme, endothelial, immune, and epithelial cell populations characterized by unique gene expression and chromatin accessibility signatures. ATAC-seq peaks defined open chromatin regions, facilitating the identification of transcription factor binding sites and candidate gene regulatory networks (GRN) involved with trophoblast differentiation. Several transcription factors, known for their involvement in trophoblast differentiation in other mammalian species, were identified as candidate regulators of uninucleate (UNC) to binucleate (BNC) trophoblast differentiation.

Some breeds are highly efficient in egg production, while others perform poorly, due to long-term selection aimed for different purposes. Female primordial germ cells (PGCs) are the precursors of eggs and the population size of PGCs will ultimately determine ovarian reserve of hens. In this study, we observed that the layers exhibit greater proliferation capacity and a higher number of PGCs compared to the broilers before meiosis. By comparing the PGC transcriptomes between layers and broilers, we identified potential genes that regulate cell proliferation. We further confirmed that FOXO3 expression is higher in broilers, where it inhibits the PGC proliferation both in vivo and in vitro. However, in layers, the upstream BMP signaling stimulate the phosphorylation of AKT and suppress FOXO3 activity. Consequently, the elevated BMP signaling and reduced FOXO3 co-operatively promote more robust PGC proliferation in layers compared to broilers and result in a greater number of PGCs in layers.

Metritis was diagnosed in lactating Holstein cows from two Florida dairies and defined by the presence of fetid, watery, reddish-brown vaginal discharge from 4 to 12 days postpartum (dpp). Cows with metritis (n = 24) were paired with cows without metritis of similar parity and dpp (n = 24). On the day of metritis diagnosis (day 0), all cows with metritis received antimicrobial therapy. The continued presence of the fetid, watery, reddish-brown discharge on day 5 (n = 16) was defined as clinical cure failure, whereas clinical cure was defined by its absence (n = 8). Metabolome analyses of uterine lavage (days 0 and 5) and serum samples (day 0) were conducted using untargeted gas chromatography time-of-flight mass spectrometry. Normalized data were analyzed using partial least squares-discriminant analysis and ANOVA, adjusting P-values for multiple comparisons. Differences in the uterine metabolome on day 0 associated with clinical cure failure were linked to carbohydrate, amino acid, and lipid metabolism. Greater concentrations of arachidonic acid, ribose, and glutaric acid were associated with clinical cure failure, suggesting a greater degree of tissue lesion and inflammation. No differences in the serum metabolome were associated with cure failure. No differences in uterine metabolome were associated with clinical cure failure on day 5.

In this study, we compared the mRNA and microRNA (miRNA) transcriptomes between young (< 32 y.o.) and AMA (> 38 y.o.) patients' GCs to identify potential ovarian aging-related molecular signatures. We identified 293 and 21 differentially expressed genes (DEGs) and miRNAs (DE miRNAs), respectively, between young and aged GCs. Highly expressed mitochondrial-encoded genes, MT-ND3, MT-ND6, and MT-CYB, were downregulated in aged GCs, indicating potential mitochondrial insufficiency. Additionally, pathway analysis indicates DEGs are involved in inflammation, cytokine signaling, extracellular matrix (ECM) remodeling, and angiogenesis. Key DEGs related to these processes include CXCL8, IL1B, NLRP3, SIGIRR, ANGPT2, ADAM8, and ADAMTS14. Additionally, target gene prediction and pathway analysis of DE miRNAs indicates their potential post-transcriptional regulation of genes associated with cell signaling, mitochondrial function, oxidative stress, apoptosis, and senescence pathways in addition to cytokine signaling, angiogenesis, and ECM remodeling. To investigate regulatory mechanisms further, we looked at the DEGs' convergence with the DE miRNAs predicted target genes and we identified miR-483-3p, miR-1268a, miR-4497, miR-7704, miR-135a-5p, miR-1261, and miR-4791 as potential crucial regulators of genes involved in pathways associated with inflammation, ECM, and angiogenesis. This data suggests that aged GCs have an impaired ability to elicit the same pro-inflammatory response combined with dysregulation of angiogenesis and ECM remodeling compared to young GCs, and miRNA may play a role in regulating key ovulatory processes.

While earlier studies demonstrated that grazing pregnant sheep on biosolids-treated pastures did not influence establishment of the ovarian reserve in fetal life, its impact on subsequent depletion of ovarian reserve during reproductive life of offspring is unknown. We hypothesized that developmental exposure to biosolids accelerates depletion of ovarian reserve.

Activation rate was increased in F1 biosolids-treated pastures juveniles with a corresponding reduction in primordial follicle density. In contrast, activation rate and ovarian reserve were similar between control and F1 biosolids-treated pastures adults. The density of anti-Müllerian hormone-positive antral follicles was lower in biosolids-treated pastures juveniles, whereas anti-Müllerian hormone expression tended to be higher in antral follicles of biosolids-treated pastures adults, consistent with the changes in the ovarian reserve.

This study aimed to investigate the expression of SCGB1D4 in IUA tissues, validate the role of SCGB1D4 in endometrial fibrosis, and assess its potential therapeutic significance by analyzing clinical features and constructing rat and cell models. Clinical characteristics of patients with intrauterine adhesions (IUA) were compared and analyzed against control subjects. Additionally, a rat uterine adhesion model was successfully established using a combination of mechanical injury and infection. The expression levels of SCGB1D4 in patient tissues and animal models were detected through immunohistochemistry, Western blot, and real-time fluorescence quantitative PCR, and the changes in fibrosis markers COL1A1 and α-SMA were also evaluated. Furthermore, human endometrial stromal cell lines (HESCs) induced by transforming growth factor-β-1 conversion were differentiated into myofibroblasts to establish cell models of intrauterine adhesion. We detected the expression of SCGB1D4 and fibrosis-related factors by real-time fluorescence quantitative PCR and Western blot. Cell proliferation and cell cycle changes were assessed using flow cytometry and CCK8. IUA patients showed increased miscarriage rates and decreased endometrial thickness. Clinical tissue specimens revealed significantly lower expression of SCGB1D4 in the endometrial tissues of IUA patients, accompanied by a notable increase in COL1A1 and α-SMA. The established rat model of intrauterine adhesion exhibited decreased expression of SCGB1D4 and a significant increase in fibrosis. After overexpression of SCGB1D4 on the IUA cell model, SCGB1D4 expression was elevated, while COL1A1 and α-SMA expression was significantly reduced. Cell proliferation was inhibited and cell cycle distribution was altered. This study has confirmed the low expression of SCGB1D4 in patients with IUA, as well as in animal and cell models.
