Article Abstract
Aim: To find new peroxisome proliferator-activated y agonists with high activity and low toxicity.
Methods: Based on JTT-501 and JTT-20993, new isoxazolidine-3,5-dione and noncyclic 1,3-dicarbonyl compounds were designed and synthesized. Their insulin-sensitizing activities were evaluated.
Results: Eight new compounds were obtained. The structures of synthesized compounds were characterized by NMR, MS and IR. Four compounds (1A-4A) showed insulin-sensitizing activities.
Conclusion: Compounds (1A and 3A) showed excellent insulin-sensitizing activities and should be worth further investigation.

MR409, a synthetic growth hormone-releasing hormone (GHRH) analogue, has demonstrated therapeutic potential in enhancing islet cell transplantation efficacy in diabetes mice and exerts beneficial effects on cardiovascular diseases. The present study investigated the renoprotective effects of MR409 on db/db and streptozotocin (STZ)-induced diabetic mice, focusing on its role in modulating oxidative stress and ferroptosis. db/db or STZ mice combined with high fat diet were used to establish the type 2 diabetic models.

Myelin is a lipid-rich substance that is crucial for neural function. Neonatal anesthesia has been linked to neurological impairments associated with myelination dysfunction. This study sought to evaluate whether disrupted fatty acid homeostasis is involved in the mechanism of sevoflurane developmental neurotoxicity.

Background: We conducted a transcriptomic analysis to examine cerebellar transcriptional changes in a mouse model of chronic intermittent alcohol exposure.
Methods: We established a mouse model of chronic intermittent alcohol exposure and conducted a cerebellar transcriptomic analysis. After identifying differentially expressed genes, we analyzed pathway enrichment using the Kyoto Encyclopedia of Genes and Genomes and Gene Ontology.

Adrenal lipomas are benign tumors containing ectopic adipose tissue in the adrenal gland, an organ that normally lacks both adipocytes and their progenitors. The origin of this ectopic fat remains enigmatic, and the absence of a genetic animal model has hindered its investigation. Phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P], a key signaling lipid that regulates cellular growth and differentiation, is tightly regulated by the lipid phosphatases PTEN (phosphatase and tensin homolog) and SHIP2 (SH2-containing inositol phosphatase 2).
