Macular telangiectasia type 2 (MacTel) is a slowly progressive macular disorder that often diagnosed late due to the gradual onset of vision loss. Recent advances in diagnostic techniques have facilitated earlier detection and shown MacTel more common than initially thought. The disease genetically complex, multiple variants contribute incrementally overall risk. familial occurrence prompted investigation genetic background MacTel. To better understand molecular milieu disease, literature review clinical reports publications investigating factors was performed. date, disease-associated been found genes involved amino acid (glycine/serine) metabolism transport, urea cycle, lipid metabolism, retinal vasculature thickness.

Abstract Background Cyclophosphamide (CTX) is the first-line medication for treatment of breast cancer, although it potentially leads to severe ovarian dysfunction and even premature failure (POF). However, mechanism CTX-induced POF remains unclear. Mesenchymal stem cell-based therapy has been wildly used treating numerous diseases. Therefore, our study aims elucidate underlying explore therapeutic effect human urine cells (hUSCs) in POF. Methods or granulosa cell (GCs) apoptosis were treated with hUSCs their exosomes vitro vivo. Morphological, histological, functional alternations examined using multiple approaches. The effector molecules hUSC-derived (hUSC-Exo) determined by differential expression analysis ovaries. target genes miRNA accessed transcriptome sequencing GCs, mechanisms further elucidated. Results remarkably inhibited promoted proliferation respectively. In addition, we observed that miR-27b-3p was highly expressed hUSC-Exo markedly suppressed GC specifically inhibiting SLC1A4, a serine transporter, which, turn, elevated concentration intracellular outflux cellular serine. More importantly, knockdown SLC1A4 simple supplementation GCs. Finally, demonstrated GCs essential reducing via elevating whereas protected against miR-27b-3p/SLC1A4/serine axis-mediated activation PI3K/AKT/mTOR signaling pathway. Conclusions Our suggests hUSC-based may provide an efficient approach prevention clinically. Graphical abstract

Increasing evidence suggests that frailty results from a complex age-associated metabolic decline. Here, we investigated the serum metabolomic profile of well-characterized cohort elderly subjects encompassing whole fit-to-frail continuum. Enrichment analyses revealed dysregulation amino acids and energy metabolism in both pre-frail frail participants. Remarkably, upregulated betaine levels emerged as specific biochemical signature females, holding promise for development novel targeted interventions.
