For example, SIRT1 activation confers a therapeutic effect in type 2 diabetes, obesity and neurodegenerative diseases such as Alzheimer's and amyotrophic lateral sclerosis, whereas inhibition of mTOR is protective against cardiovascular and neurological diseases, diet-induced obesity and cancer [31], [32], [33], [34], [35], [36], [37], [38]. This evidence concerns the gene MTOR and obesity due to melanocortin 4 receptor deficiency.
