Maternal exercise programs placental miR-495-5p-mediated Snx7 expression and kynurenic acid metabolic pathway induced by prenatal high-fat diet: Based on miRNA-seq, transcriptomics, and metabolomics.

Poor intrauterine environments increase the prevalence of chronic metabolic diseases in offspring, whereas maternal exercise is an effective measure to break this vicious intergenerational cycle. Placenta is increasingly being studied to explore its role in maternal-fetal metabolic cross-talk. The association between placental miRNA and offspring development trajectories has been established, yet the specific role and mechanism thereof in maternal exercise-induced metabolic protection remain elusive.

Article Synopsis
- The study investigates the role of lncRNA GAS5 in regulating glucose metabolism and ferroptosis in endothelial progenitor cells (EPCs) amidst coronary heart disease (CHD).
- Researchers used various assays to analyze cell behavior, glucose uptake, and markers of ferroptosis, finding GAS5 levels were decreased in CHD patients compared to healthy individuals.
- Results indicate that GAS5 depletion negatively impacts EPC proliferation, migration, and increases apoptosis, while GAS5 enhances glucose metabolism and protects against ferroptosis by influencing the NRF2 and SIX1 pathways.
miR-495 promotes intestinal epithelial cell apoptosis through downregulation of Sphingosine-1-phosphate.
Physiol Rep

Baltimore Veterans Affairs Medical Center, Baltimore, Maryland, USA.
Many pathological conditions lead to defects in intestinal epithelial integrity and loss of barrier function; Sphingosine-1-phosphate (S1P) has been shown to augment intestinal barrier integrity, though the exact mechanisms are not completely understood. We have previously shown that overexpression of Sphingosine Kinase 1 (SphK1), the rate limiting enzyme for S1P synthesis, significantly increased S1P production and cell proliferation. Here we show that microRNA 495 (miR-495) upregulation led to decreased levels of SphK1 resultant from a direct effect at the SphK1 mRNA.

Terpenoids from quinoa reverse drug resistance of colon cancer by upregulating miR-495-3p.

Background: Quinoa contains far more nutrients than any traditional grain crop. It is known that terpenoids in quinoa have anti-inflammatory and antitumor effects, but their role in reversing drug resistance remains unclear.
Results: Our previous studies showed that quinoa-derived terpenoid compounds (QBT) can inhibit the occurrence and development of colon cancer.
