What foods inhibit mTOR?

Diet-derived natural products. Increasing studies have demonstrated that some diet-derived natural products, including curcumin, resveratrol, epigallocatechin gallate (EGCG), genistein, 3, 3-diindolylmethane (DIM) and caffeine, may inhibit mTOR signaling directly or indirectly (Table 1) [140-147].

What happens if mTOR is inhibited?

The inhibition of mTOR blocks the binding of the accessory protein raptor (regulatory-associated protein of mTOR) to mTOR, but that is necessary for downstream phosphorylation of S6K1 and 4EBP1. As a consequence, S6K1 dephosphorylates, which reduces protein synthesis and decreases cell mortality and size.

Does caffeine inhibit mTOR?

Caffeine has been reported to inhibit some kinase activities, including various forms of phosphoinositol-3 kinase and mammalian target of rapamycin (mTOR).

What can mTOR inhibition cause?

Caloric restriction achieves mTOR inhibition through two pathways: decreased PI3K activity and increased AMPK activity (Figure 2). Cells in low energy states (calorically restricted) have low PI3K activity, lowering Akt activity, which then lowers mTORC1 via inhibition by Tsc1/2 (Figure 3).

Does rapamycin inhibit mTOR?

Rapamycin does not directly inhibit mTOR but binds to its immunophilin, FK binding protein (FKBP12). This effect results in a 15% to 20% inhibition of overall protein translation and leads to cell cycle arrest (12) .

Can you take metformin and rapamycin together?

The combination of metformin and rapamycin (Met+Rap) activates AMPK and decreases mTORC1 signaling, events that could increase allocation of energetic resources to maintaining proteostasis. Treatment with Met+Rap further extends median and maximal life span compared with Rap alone (18).

Does coffee raise insulin levels?

Caffeine may lower your insulin sensitivity. That means your cells don’t react to the hormone by as much as they once did. They don’t absorb as much sugar from your blood after you eat or drink. This causes your body to make more insulin, so you have higher levels after meals.
