Project description:The root of Vicatia thibetica de Boiss is a Chinese herb medicine with homology of medicine and food. We first report that HLB01 (the extract of Vicatia thibetica de Boiss root) extends lifespan and promotes healthy parameters in Caenorhabditis elegans (C. elegans). In doxorubicin-induced senescent mice, HLB01 counteracts senescence associated biomarkers significantly, including AST, ALT, p21 and γH2AX. Interestingly, HLB01 promotes the level of collagen in C. elegans and mammalian cell systemically, which might be one of the essential factors to exert anti-aging effects of HLB01. In addition, HLB01 can scavenge free radical to perform antioxidant ability. Lifespan extension of HLB01 also dependent on DAF-16 and HSF-1 to perform oxidative stress resistance and heat stress resistance. Taken together, these data indicate that HLB01 extends lifespan and healthspan of C. elegans, resists doxorubicin‐induced senescence in mice via collagen promoting, antioxidant and stress resistance.
