GDF11 administration does not extend lifespan in a mouse model of premature aging

چکیده
GDF11 has recently emerged as a powerful anti-aging candidate, found in young blood, capable of rejuvenating a number of aged tissues, such as heart, skeletal muscle and brain. However, recent reports have shown contradictory data questioning its capacity to reverse age-related tissue dysfunction. The availability of a mouse model of accelerated aging, which shares most of the features occurring in physiological aging, gives us an excellent opportunity to test in vivo therapies aimed at extending lifespan both in pathological and normal aging. On this basis, we wondered whether the proposed anti-aging functions of GDF11 would have an overall effect on longevity. We first confirmed the existence of a reduction in GDF11/8 levels in our mouse model of accelerated aging compared with wild-type littermates. However, we show herein that GDF11 daily administration does not extend lifespan of premature-aged mice.

Introduction: exercise interventions can play an important role in delaying aging. Klotho protein and Growth Differentiation Factor 11 (GDF11) are a new family of biochemical theories of the aging process. The aim of the present study was to investigate the effect of 12 weeks of resistance training on serum levels of Klotho anti-aging proteins and rejuvenating of GDF11 factor in elderly men. Me...
متن کاملThe Effect of Peripheral Injection of Leptin on Biomarkers of Aging in Calorie Restricted Rats
Background and Objectives: Calorie restriction (CR) is one of the proven methods of extending lifespan and slowing aging. Leptin is a nutritionally regulated adipokine that has been proposed as a possible key signal in the adaptive responses relevant to CR. Under CR, plasma leptin levels decrease, thus it was hypothesized that leptin administration may counteract CR-induced weight loss. Therefo...

Aging is an intricate process that increases susceptibility to sarcopenia and cardiovascular diseases. The accumulation of mitochondrial DNA (mtDNA) mutations is believed to contribute to mitochondrial dysfunction, potentially shortening lifespan. The mtDNA mutator mouse, a mouse model with a proofreading-deficient mtDNA polymerase γ, was shown to develop a premature aging phenotype, including ...

It is well documented that life expectancy in developed countries at birth is going to increase from the 20th century. However, regrettably, a potential decline in life expectancy has been proposed for these nations in the 21st century due to a rapid upsurge in the prevalence of fatal degenerative diseases like cardiovascular diseases (CVD), cancer and diabetes. Collectively, these three diseas...
