- Abstract
The effects of different concentrations (0.1, 1, 10, 50 µg· mL-1) of Sanghuangporus vaninii water extract on average life span, median-lethal time, maximum life span, number of pupae and number of F1 adults of Drosophila melanogaster were studied. The expression levels of 13 genes pertaining to longevity, immunity and energy metabolism were determined by qPCR at 1, 3, 5, 10 and 20 d upon feeding D. melanogaster with 1 µg· mL-1 S. vaninii water extract. The results showed that in the experimental range, 1.0 µg·mL-1 water extract prolonged median-lethal time, average life span, and increasesd F1 adult number as compared with the control. Median-lethal time was also prolonged under 0.1 µg· mL-1 S. vaninii water extract. The relative expression levels of TEP, BrC, E74B and JHEH were higher at 3 d than other time. The expression levels of INDY, EcRB, Srl and TPI were higher at 10 d than other time. The expression levels of TotA, Dros and TotX were higher at 20 d than other time.
