Curcumin Extends Life Span, Improves Health Span, and Modulates the Expression of Age-Associated Aging Genes in Drosophila melanogaster.
Summary of "Curcumin Extends Life Span, Improves Health Span, and Modulates the Expression of Age-Associated Aging Genes in Drosophila melanogaster."
Abstract Background: Curcumin, an extract from the rhizome of the plant Curcuma longa (turmeric), has been widely used as a spice and herbal medicine in Asia. It has been suggested to have many biological activities, such as antioxidative, antiinflammatory, anticancer, chemopreventive, and antineurodegenerative properties. We evaluated the impact of curcumin on life span, fecundity, feeding rate, oxidative stress, locomotion, and gene expression in two different wild-type Drosophila melanogaster strains, Canton-S and Ives, under two different experimental conditions. Results: We report that curcumin extended the life span of two different strains of D. melanogaster, an effect that was accompanied by protection against oxidative stress, improvement in locomotion, and chemopreventive effects. Life span extension was gender and genotype specific. Curcumin also modulated the expression of several aging-related genes, including mth, thor, InR, and JNK. Conclusions: The observed positive effects of curcumin on life span and health span in two different D. melanogaster strains demonstrate a potential applicability of curcumin treatment in mammals. The ability of curcumin to mitigate the expression levels of age-associated genes in young flies suggests that the action of curcumin on these genes is a cause, rather than an effect, of its life span-extending effects.

Medical and Biotech [MESH] Definitions
National Institute Of Nursing Research (u.s.)
Component of the NATIONAL INSTITUTES OF HEALTH. It conducts and supports clinical and basic research to establish a scientific basis for the care of individuals across the life span, from the management of patients during illness and recovery to the reduction of risks for disease and disability; the promotion of healthy lifestyles; the promotion of quality of life in those with chronic illness; and the care for individuals at the end of life. It was established in 1986.
Drosophilidae
A family of the order DIPTERA. These flies are generally found around decaying vegetation and fruit. Several species, because of their short life span, giant salivary gland chromosomes, and ease of culturing, have been used extensively in studies of heredity.
Sexual Development
The processes of anatomical and physiological changes related to sexual or reproductive functions during the life span of a human or an animal, from FERTILIZATION to DEATH. These processes include SEX DIFFERENTIATION; SEXUAL MATURATION; and changes during AGING.
Erythrocyte Aging
The senescence of RED BLOOD CELLS. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days.
Fertile Period
The period in the MENSTRUAL CYCLE that is optimal for FERTILIZATION of the OVUM and yielding PREGNANCY. The duration of fertile period depends on the life span of male GAMETES within the female reproductive tract and the time of OVULATION. It usually begins a few days before ovulation and ends on the day of ovulation.
