Liver ageing is a significant risk factor for chronic liver diseases. Anthocyanin is a food additive that has previously shown efficacy in increasing longevity. Here, we tested whether anthocyanins could protect young mice from accelerated ageing of the liver. Kunming mice were injected with D-galactose to accelerate ageing and were given 20 or 40 mg/kg anthocyanins as an intervention. After eight weeks, whole liver function and structure were evaluated, and the expression levels of genes involved in the DNA damage signalling pathway were assessed by Western blot analysis. Anthocyanins delayed the reduction of the liver index (p < 0.05), hepatic tissue injury and fibrosis. Anthocyanins also maintained the stability of the redox system (GSH-PX, T-SOD and MDA) in plasma and liver structures (p < 0.001) and reduced the levels of inflammatory factors (IL-1, IL-6 and TNF-α) in the liver (p < 0.05). Moreover, the expression levels of sensors (ATM and ATR), mediators (H2AX and γ-H2AX) and effectors (Chk1, Chk2, p53 and p-p53) in the DNA damage signalling pathway were all reduced. Anthocyanins could be widely used in the field of health products to slow ageing-related deterioration of liver function and structure by inhibiting DNA damage.
