This dataset showed that mitovesicles, extracellular vesicles (EVs) of mitochondrial origin, are altered in Down syndrome (DS). Mitochondrial dysfunction is a distinctive feature of aging and neurodegenerative disorders, such as DS and Alzheimer’s disease. For this study, a high-resolution density gradient separation of EVs isolated from murine and human DS and diploid control brains was used. Using...

Long interspersed element-1 (LINE-1) is an autonomous retroelement that utilizes copy and paste mechanism to propagate themselves throughout the genome through a process called retrotransposition. The LINE-1 bicistronic mRNA codes for two proteins, ORF1p and ORF2. While LINE-1 transcription is usually repressed in most healthy somatic cells, ORF1p expression has been observed in tumors, including prostate...

Neurological dysfunction associated with Down syndrome (DS) is the concomitant basal forebrain cholinergic neuron (BFCN) degeneration and onset of Alzheimer’s disease (AD) pathology. Previously, single population RNA sequencing analysis in the Ts65Dn (Ts) mouse model of DS revealed that the mitochondrial oxidative phosphorylation pathway was significantly impacted, where a large subset of genes within...

This study used proteomic analysis, respirometry, and electron microscopy to examine the development of condensed mitochondria. The dataset contains proteomic and imaging data. The data indicate that condensed mitochondria formed from orthodox mitochondria during meiosis in order to support the formation of the acrosomal matrix. Condensed mitochondria also respired more actively and contained more...

Psychological stress is linked with systemic inflammation. It accelerates inflammatory disease progression and monocytes are key in sustaining systemic inflammation. However, the mechanisms underlying stress-mediated inflammation and future health risk remains unknown. This study examined the impact of psychological stress on monocytes and showed that psychological stress induces remodeling of the...

Eukaryotic cells upregulate oxidative metabolism to maintain homeostasis upon glucose restriction. This study used CRISPR/Cas9-based screening to identify serine catabolic enzyme SHMT2. They found that the mitochondrial SHMT2 is required for robust mitochondrial oxygen consumption and low glucose proliferation. This dataset contains immunoblot images, as well as supplementary data tied to the publication....

Fluoride is a naturally occurring mineral that helps build strong teeth and prevent cavities. However, excessive fluoride intake causes dental fluorosis, which are enamel defects that can increase the risk of tooth decay. This study examined the effects of fluoride exposure in enamel cells to assess its impact on calcium signaling. For their investigation, they isolated primary EO cells from Sprague...

Microsporidia are obligate intracellular pathogens that infect a wide range of invertebrate and vertebrate hosts, including humans. In humans, microsporidia most often infect the gastrointestinal tract and cause diarrheal diseases, but in immunocompromised patients, infections can be fatal. Previous knowledge of microsporidian intracellular development was based on 2D transmission electron microscopy...
