They artificially accelerated autophagy by boosting the activity of a protein called Nrf2 in these neurons, which in turn prolonged cell survival.

Autophagy (more specifically macroautophagy) is the process by which cellular compartments, such as membranes and organelles and also protein aggregates, are recycled back into their building blocks [122].

Neurodegeneration - associated aggregation - prone proteins are predominantly degraded by autophagy and therefore stimulating this process with chemical inducers is beneficial in a wide range of transgenic disease models.

This process, called autophagy, is normally used by a cell to recycle damaged organelles and proteins, but is also co-opted by cancer cells to meet their increased energy and metabolic demands.

Wang S, Brubaker G, Robinet P, Smith JD, Gulshan K. ORMDL orosomucoid - like proteins are degraded by free cholesterol loading induced autophagy.

On the one hand, autophagy functions as a tumor suppressor mechanism by preventing the accumulation of damaged organelles and aggregated proteins.

Stress resistance has not been assessed however and so the biological relevance of this finding is currently unknown.32 Several IER trials (75 - 85 % ER on restricted days) in overweight / obese populations have reported reductions in various markers of oxidative stress 37, 41, which in one study was accompanied by a complementary increase in the anti-oxidant uric acid.37 In a direct comparison of IER (75 % ER for two days / week) and CER, both ER strategies displayed equal efficacy in reducing levels of fast - acting advanced oxidation protein products (AOPP) after six months, which displayed a tendency to occur earlier (i.e. at three months) in the IER group.41 Levels of slow - acting (i.e. long term) AOPP tended to decrease in the IER group and increase in the CER group which the authors proposed may have resulted from IER - induced activation of autophagy, a key homeostatic cellular process in which dysfunctional or unnecessary cellular proteins are degraded and recycled.41 On the other hand, a follow - up study using similar IER / CER protocols demonstrated comparable reductions in AOPP in both groups after three months.48 Summary and Future Research Directions
