Fig. 5From: Antiaging effect of a Jianpi-yangwei formula in Caenorhabditis elegansEffects of JPYW treatment on the expression of aging-related genes. The expression levels of aging-related genes were determined by qRT-PCR using the 2−ΔΔCT method in worms with or without 150 μg/ml JPYW treatment at 20 °C. The graph shows the mean and SEM values from two independent experiments. Compared to the control treatment, JPYW treatment significantly changed the expression levels of the genes daf-16, clk-2, skn-1 and sir-2.1 (P < 0.05), but not those of the gene sod-3 (P > 0.05)Back to article page
