Rheumatoid arthritis (RA), a chronic systemic inflammatory disease, is a primary cause of disability worldwide. The involvement of fibroblast-like synoviocytes (FLSs) in the regulation of the pathogenesis of RA has been highlighted. Mesenchymal stem cells (MSCs) are important candidates for cell-based treatment in many inflammatory autoimmune diseases. Herein, we identify whether MSC-derived exosomes loaded with microRNA-320a (miR-320a) regulate RA-FLSs. Synovial tissues from 22 patients with RA and 9 patients with osteoarthritis were collected. RA-FLSs were obtained from patients with RA, and their functions were evaluate...

In conclusion, our results suggest a previously unknown mechanism whereby the canonical NF-κB cascade and a mitochondrial fission pathway interdependently regulate endothelial inflammation. Lin28 as a Target for Nerve Regeneration https://www.fightaging.org/archives/2020/05/lin28-as-a-target-for-nerve-regeneration/ Researchers here show that the gene Lin28 regulates axon regrowth. In mice, raised levels of Lin28 produce greater regeneration of nerve injuries. Past research has investigated Lin28 from the standpoint of producing a more general improvement in regenerative capacity. It improves mitoch...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

Mammalian articular cartilage is an avascular tissue with poor capacity for spontaneous repair. Here, we show that embryonic development of cartilage in the skate (Leucoraja erinacea) mirrors that of mammals, with developing chondrocytes co-expressing genes encoding the transcription factors Sox5, Sox6 and Sox9. However, in skate, transcriptional features of developing cartilage persist into adulthood, both in peripheral chondrocytes and in cells of the fibrous perichondrium that ensheaths the skeleton. Using pulse-chase label retention experiments and multiplexed in situ hybridization, we identify a population of cyclingS...

In this study, we found that older nematodes have higher ROS levels. Interestingly, after hydrogen treatment, the ROS levels were significantly decreased, and hydrogen could significantly extend the lifespans of the N2, sod-3 and sod-5 mutant strains, by approximately 22.7%, 9.5%, and 8.7%, respectively. In addition, aging is regulated by a variety of pathways, such as the insulin signaling pathway, the rapamycin target signaling pathway, and the caloric restriction pathway. However, our results showed that the lifespans of the daf-2 and daf-16 strains, in which these pathways are upregulated, were not affected afte...

In this study the effects and mechanisms of Y1R antagonist on prevention for osteoporosis were characterized. In the clinical experiment, compared with osteoarthritis (OA), osteoporosis (OP) showed significant osteoporotic bone microstructure and accumulation of bone microdamage. NPY and Y1R immunoreactivity in bone were stronger in OP group, and were both correlated with bone volume fraction (BV/TV). In vivo experiment, Y1R antagonist significantly improved osteoporotic microstructure in the ovariectomized (OVX) rats. And Y1R antagonist promoted RUNX2, OPG and inhibit RANKL, MMP9 in bone marrow. In vitro cell culture expe...

This study aims to investigate the regulatory role of exosomal microRNA-9-5p (miR-9-5p) secreted by bone marrow –derived MSCs (BM-MSCs) on OA in a rat model induced by anterior cruciate ligament/medial collateral ligament transection. Luciferase reporter assay was conducted to verify the putative miR-9-5p binding sites to 3′UTR of syndecan-1 (SDC1). Additionally, an intra-articular injection of miR-9-5p c arried by BM-MSC–derived exosomes or liposomes into rats with OA-like damage was performed to ascertain the role of exosomal miR-9-5p and a gain-of-function study of SDC1 was carried out to explore the p...
