Naringenin is a Senotherapeutic that Enhances Neurogenesis in Mice

Researchers here evaluate the flavonoid naringenin for its ability to dampen the inflammatory signaling of senescent neural cells, particularly levels of TNF-α, and increase neurogenesis in mice. This increased neurogenesis is likely a result of reduced inflammation in brain tissue, but possibly due to other, distinct mechanisms. Neurogenesis is the name given to the generation of new neurons in the brain, and their integration into existing neural circuits. Evidence suggests that increased neurogenesis is a good thing at any age, improving cognitive function and making the brain more resilient to injury. Now that the research community is paying attention to senescent cells and their signaling in the context of aging, we'll no doubt see a great many compounds classified or reclassified as senotherapeutics in the years ahead. The use of metabolomic analysis to investigate the specific composition of Ribes meyeri anthocyanins revealed that naringenin (Nar) may be an important flavonoid metabolite. Nar has previously been reported to ameliorate myocardial cell senescence, improve the metabolic capacity of the intestinal tract, and exert anti-inflammatory and anti-cancer effects. However, the effects of Nar on neural stem cells (NSCs) during aging remains unknown. To explore the anti-aging effects of R. meyeri anthocyanins, we conducted further studies using Nar. Treatment with 6.8 μg/mL Nar increased cell viability, reduced P16ink4a gene expression, lengthened...
