In Aging Cell, researchers have published details on the pathway by which a compound commonly found in ketone bodies ameliorates osteoarthritis in a rat model. Chondrocytes are crucial in arthritis The cartilage holding joints together is built and maintained by chondrocytes, which synthesize such necessary proteins as collagen and aggrecan [1]. Unfortunately, the cellular senescence...

In iScience, researchers have explained how physical mechanics can alter mitochondrial function in a way that leads to osteoarthritis. When simple physics affects biology Previous work has pinpointed abnormal mechanical loading, which occurs when joints are placed under excessive stresses in ways that they were not meant to handle, as a key driver of osteoarthritis...

Rejuvenate Bio has announced a partnership with a leading animal health company to develop a gene therapy for canine osteoarthritis. The identity of the partnering global company is as yet unknown. This San Diego-based biotech was co-founded in 2017 by Professor George Church of Harvard Medical School. It is focused on dog longevity research and...

Researchers have described how specialized nanoparticles, which deliver rapamycin and the antioxidant astaxanthin, restore macrophage balance and reduce inflammation in a mouse model of osteoarthritis. A matter of polarization Inflammation is a critical part of arthritis. Previous studies have found that inflammation of the membranes in joints (synovitis) strongly contributes to osteoarthritis [1]; in fact,...

In Aging, researchers have published their tests of a compound that counteracts the effects of tumor necrosis factor alpha (TNF-α), an inflammatory factor that promotes arthritis. Current anti-inflammatories aren't enough Rheumatoid arthritis, an autoimmune disorder that causes joint swelling, pain, and disability, is most often treated with anti-inflammatory compounds, such as non-steroidal anti-inflammatory drugs (NSAIDs),...

In a paper published on Saturday in Aging, researchers have described a method of activating the sirtuin SIRT6 to reduce DNA damage, reducing senescence and possibly treating arthritis. Sirtuins, genetic damage, and senescence Extensive previous research has found that SIRT6, a deacetylase that is dependent on NAD+, is instrumental in DNA repair [1] and naturally...
