Mitochondrial dysfunction-mediated metabolic remodeling of TCA cycle promotes Parkinson's disease through inhibition of H3K4me3 demethylation.

Parkinson's disease (PD), a neurodegenerative disorder caused by complex factors, is usually associated to mitochondrial dysfunctions but the links between such disorder and PD remain object of research. Here, we report that impaired mitochondrial quality control (MQC) system is a molecular basis of the mitochondrial dysfunction in PD and that tricarboxylic acid cycle (TCA cycle) disorder is the main feature of such mitochondrial dysfunction. Multi-omics analysis revealed that MDH2, OGDHL and IDH3G enzymes are bottlenecks in the enzymatic reactions of the TCA cycle in PD.

Transcriptional conservation between mouse and pig was determined by comparative analysis of transcriptomes.

Expression Profiling and Function Analysis Identified New Cumulus Cells-Expressed Genes and miRNAs Predictive of Oocyte Developmental Potential.

Although prior studies have identified cumulus cells (CCs)-expressed genes and miRNAs that regulate cumulus expansion and/or CC apoptosis and may serve as markers for selecting competent oocytes and embryos, there remains an urgent need to identify CCs-expressed genes and miRNAs whose expression levels are directly correlated with oocyte developmental potential (DP). In this study, we first established CC models from mouse cumulus-oocyte complexes (COCs) that exhibited significantly different DP following in vitro or in vivo maturation. Subsequently, we performed mRNA/miRNA sequencing and functional analyses using these in vitro and in vivo CC models.

Identification of biomarkers in Parkinson's disease by comparative transcriptome analysis and WGCNA highlights the role of oligodendrocyte precursor cells.

Cyanidin-3--glucoside Mitigates the Ovarian Defect Induced by Zearalenone p53-GADD45a Signaling during Primordial Follicle Assembly.

Zearalenone (ZEN) is well known as a kind of endocrine disruptor whose exposure is capable of causing reproductive toxicity in animals. Cyanidin-3--glucoside (C3G) is a derivative of cyanidin and owns multiple biofunctions, and prior efforts have suggested that C3G has therapeutic actions for reproductive diseases. In this article, a ZEN exposure model during primordial follicle assembly was constructed using the culture platform of neonatal mouse ovaries.

Induced differentiation of primordial germ cell like cells from SOX9 porcine skin derived stem cells.

Understanding the mechanisms behind porcine primordial germ cell like cells (pPGCLCs) development, differentiation, and gametogenesis is crucial in the treatment of infertility. In this study, SOX9 skin derived stem cells (SOX9 SDSCs) were isolated from fetal porcine skin and a high-purity SOX9 SDSCs population was obtained. The SOX9 SDSCs were induced to transdifferentiate into PGCLCs during 8 days of cultured.

Placental galectins: a subfamily of galectins lose the ability to bind β-galactosides with new structural features†.

Galectins are a phylogenetically conserved family of soluble β-galactoside binding proteins. There are 16 different of galectins, each with a specific function determined by its distinct distribution and spatial structure. Galectin-13, galectin-14, and galectin-16 are distinct from other galectin members in that they are primarily found in placental tissue.

LncRNA profiles of Cyanidin-3-O-glucoside ameliorated Zearalenone-induced damage in porcine granulosa cells.

Long non-coding RNA (lncRNA), a class of RNA molecules with transcripts longer than 200 nt, is crucial for maintaining animal reproductive function. Zearalenone (ZEN) damaged animal reproduction by targeting ovarian granulosa cells (GCs), especially in pigs. Nonetheless, it is not quite clear that whether Cyanidin-3-O-glucoside (C3G) exert effects on porcine GCs (pGCs) after ZEN exposure by altering lncRNA expression.

Cross-species analysis of transcriptome emphasizes a critical role of TNF-α in mediating MAP2K7/AKT2 signaling in zearalenone-induced apoptosis.

Zearalenone (ZEN) is a widespread and transgenerational toxicant that can cause serious reproductive health risks, which poses a potential threat to global agricultural production and human health; its estrogenic activity can lead to reproductive toxicity through the induction of granulosa cell apoptosis. Herein, comparative transcriptome analysis, single-cell transcriptome analysis, and weighted gene co-expression network analysis (WGCNA) combined with gene knockout in vivo and RNA interference in vitro were used to comprehensively describe the damage caused by ZEN exposure on ovarian granulosa cells. Comparative transcriptome analysis and WGCNA suggested that the tumor necrosis factor (TNF)-α-mediated mitogen-activated protein kinase 7 (MAP2K7)/ AKT serine/threonine kinase 2 (AKT2) axis was disordered after ZEN exposure in porcine granulosa cells (pGCs) and mouse granulosa cells (mGCs).

Xanthorrhizol inhibits mitochondrial damage, oxidative stress and inflammation in LPS-induced MLE-12 cells by regulating MAPK pathway.

LPS-induced injury in lung epithelial cells is a crucial part of the process of acute lung injury (ALI). The aim of this study is to explore whether Xanthorrhizol, a medicine that has antioxidant and anti-inflammatory activity, could mitigate the injury of lung epithelial cells caused by LPS. Mouse lung epithelial cell line (MLE-12 cells) were treated with LPS in the absence and presence of Xanthorrhizol.

Aging-related aneuploidy is associated with mitochondrial imbalance and failure of spindle assembly.

Despite aging is closely linked to increased aneuploidy in the oocytes, the mechanism of how aging affects aneuploidy remains largely elusive. Here, we applied single-cell parallel methylation and transcriptome sequencing (scM&T-seq) data from the aging mouse oocyte model to decode the genomic landscape of oocyte aging. We found a decline in oocyte quality in aging mice, as manifested by a significantly lower rate of first polar body exclusion (P < 0.

Linker remodels human Galectin-8 structure and regulates its hemagglutination and pro-apoptotic activity.

Numerous articles have reported the involvement of linker in regulating bioactivity of tandem-repeat galectins. We hypothesize that linker interacts with N/C-CRDs to regulate the bioactivity of tandem-repeat galectins. To further investigate structural molecular mechanism of linker in regulating bioactivity of Gal-8, Gal-8LC was crystallized.

Identification of unique transcriptomic signatures through integrated multispecies comparative analysis and WGCNA in bovine oocyte development.

Background: Cattle (Bos taurus) are a major large livestock, however, compared with other species, the transcriptional specificity of bovine oocyte development has not been emphasised.

Results: To reveal the unique transcriptional signatures of bovine oocyte development, we used integrated multispecies comparative analysis and weighted gene co-expression network analysis (WGCNA) to perform bioinformatic analysis of the germinal follicle (GV) and second meiosis (MII) gene expression profile from cattle, sheep, pigs and mice. We found that the expression levels of most genes were down-regulated from GV to MII in all species.

Aflatoxin B1 disrupts testicular development via the cell cycle-related Ras/PI3K/Akt signaling in mice and pig.

Aflatoxins B1 (AFB1), a type I carcinogen widely present in the environment, not only poses a danger to animal husbandry, but also poses a potential threat to human reproductive health, but its mechanism is still unclear. To address this question, multi-omics were performed on porcine Sertoli cells and mice testis. The data suggest that AFB1 induced testicular damage manifested as decreased expression of GJA1, ZO1 and OCCLUDIN in mice (p < 0.
