Wanke, V. et al. Caffeine extends yeast lifespan by targeting TORC1.
However, while these findings raise great hope to improve health-span and extend lifespan by targeting metabolic signaling pathways, many issues remain to be resolved before these interventions can be effectively applied to clinic.
Also some drugs, other than rapalogs, can alter lifespan by targeting the mTOR pathway [ 102- 109].
Once revealed that long-lived fruit flies exhibit limited cardiac decline, we investigated whether Rpd3 downregulation would improve stress resistance and/or lifespan when targeted in the heart.
Strikingly, three dietary intervention network design patterns were uncovered: (1) lifespan-extending interventions largely repressed the expression of miRNAs, lncRNAs, and transposable elements; (2) protein-coding mRNAs with expression positively correlated with long lifespan are highly targeted by miRNAs; and (3) miRNA-targeting interactions mainly target chromatin-related functions.
The SSc replenishes fuel from the depot and then extends the lifespan of the target satellites via refueling.
In Drosophila, insulin-like peptides (dilps) have been shown to mediate the effects of the P C ratio on lifespan by regulating target of brain insulin (tobi), which encodes an α-glucosidase (Buch et al., 2008).
Tissue-specific induction of Imp-L2 appeared to selectively target lifespan and not other IIS regulated traits since, with both dilp2GAL4 and S 1 106 drivers, there was no effect on fecundity, stress resistance or 4E-BP expression (Fig. S8).
Thus, while DR and IIS clearly affect lifespan through independent targets, there may also be some prolongevity targets that are convergently regulated by these pathways.
Overheating is known to be one of the major deficiencies in reaching the targeted lifespan goals.
