Aging is the greatest risk factor for most neurodegenerative diseases, which is associated with decreasing cognitive function and significantly affecting life quality in the elderly. Computational analysis suggested that 4 anthocyanins from chokeberry fruit increased Klotho (aging-suppressor) structural stability, so we hypothesized that chokeberry anthocyanins could antiaging. To explore the effects of anthocyanins treatment on brain aging, mice treated with 15 or 30 mg/kg anthocyanins by gavage and injected D-galactose accelerated aging per day. After 8 weeks, cognitive and noncognitive components of behavior were determined. Our studies showed that anthocyanins blocked age-associated cognitive decline and response capacity in senescence accelerated mice. Furthermore, mice treated with anthocyanins-supplemented showed better balance of redox systems (SOD, GSH-PX, and MDA) in all age tests. Three major monoamines were norepinephrine, dopamine, and 5-hydroxytryptamine, and their levels were significantly increased; the levels of inflammatory cytokines (COX2, TGF-β1, and IL-1) transcription and DNA damage were decreased significantly in brains of anthocyanins treated mice compared to aged models. The DNA damage signaling pathway was also regulated with anthocyanins. Our results suggested that anthocyanins was a potential approach for maintaining thinking and memory in aging mice, possibly by regulating the balance of redox system and reducing inflammation accumulation, and the most important factor was inhibiting DNA damage.
