SIRT1 and cancer: On the one hand, an increase in the expression of tumor suppressor genes has been observed in cells exposed to treatments with β-OHB, in line with what was expected according to previous research that demonstrates that healthy dietary habits and dietary compounds produce positive changes in tumor suppressor genes [59, 60], as well as an increase in expression in genes related to antioxidant protection, some of them with contradictory functions depending on the type of cell or type of cancer [61–63], such as SIRT1 [63] or SIRT6 [61, 64, 65].
