Reporter brief
USP22 protein reduces senescence in bone marrow stem cells exposed to oxidative stress in vitro
What happened
This in vitro study examined how USP22 affects bone marrow mesenchymal stem cells (BMSCs) exposed to hydrogen peroxide to simulate oxidative stress. Researchers found that USP22 stabilized the SPI1 protein through deubiquitination, which increased NAMPT expression and NAD+ levels, reducing cellular senescence markers and preserving the cells' capacity to differentiate into bone tissue.
