Null mutation in Thor (alias d4E-BP) causes a significant decrease in longevity (-25% median lifespan in males) [2579]. Thor is upregulated on the protein level in a foxo-independent manner upon DR, while it is transcriptionally induced in a foxo-dependent fashion by starvation. Thor null mutants cancel out DR-induced lifespan extension, because mutants exhibit a diminished change in lifespan when nutrient conditions were varied. Ubiquitously expression of Thor rescued DR response in females and males. Ubiquitously overexpression of wild-type Thor causes no change under ad libitum, but an activated allele (with more than 3-fold increased binding activity to delF4E) significantly extends lifespan of females (weak allele) and females as well as males (strong allele). Mean lifespan is extended by 11 to 40%. Median lifespan of males and females is enhanced by 11 and 22%, respectively. Maximum lifespan is extended by 16 and 18% for males and females, respectively. Under DR (0.25% YE) there is no lifespan extension, beyond the effect of DR alone, in all (wild-type, weak and strong) Thor alleles [2547].
