Increasing gene dosage via homogeneous and moderate overexpression, while retaining its normal pattern of tissue expression of Pten increases mean, median and maximum lifespan in both females and males. Mean lifespan is extended by 18% (males), 11% (females) and 14% (both). Median lifespan in males, females and both increases by 12%, 16% and 12%, respectively [22405073]. Transgenic Pten mice carrying the additional genomic copies of Pten are protected from cancer and present a significant extension of lifespan that is independent of their lower cancer incidence. Pten(g) mice have an increased energy expenditure and protection from metabolic pathologies [22405073].
Mean: +14
