EFFECT OF LYCOPENE ON LIFESPAN OF DROSOPHILA AND ITS UNDERLYING MOLECULAR MECHANISM / 营养学报

Objective To explore the effects of lycopene on lifespan in drosophila and the underlying mechanism. Method Drosophila aged 30 d were reared in medium containing 0,2.5,7.5,22.5 ?g/g lycopene till they all die. The average lifespan and the average maximum lifespan were determined. Male drosophila aged 30 d were divided into control group and experiment group and cultured in medium supplemented with 0,22.5 ?g/g lycopene. The gene expression was determined 10,20 d later. Results The average maximum lifespan of male drosophila was increased with 2.5,7.5 ?g/g lycopene supp-lementation(P
