Is there a molecular program that determines the length of life?
Almost exclusively, research in longevity has centered on a single goal: to find genes, drugs or interventions that promote longevity? Yet, one cannot deny that a deeper and more mysterious question seemed to have escaped attention: whereby lays the molecular code that programs lifespan values? For it is evident that different mammalian species are somehow programmed with differences in lifespan. Mice, for example, die of old age after three years of life while fruit bats can surpass the age of 40. One wonders … if we identify the molecular mechanisms that program these species dependent differences in lifespan … can lifespan be reprogrammed rather than mildly extended
