   2.3.1.B41 | H133Y |
when human Sirt6 wild-type enzyme is overexpressed in Sirt6 KO MEF cells, tumor necrosis factor alpha has lower fatty acylation level than tumor necrosis factor alpha from cells without overexpression of human Sirt6, while overexpression of human Sirt6 H133Y catalytic mutant does not have much effect on tumor necrosis factor alpha fatty acylation |

generation of brS6KO mice, phenotype, overview. Brains of brS6KO mice are significantly smaller, but otherwise structurally normal. brS6KO mice exhibit increased signs of DNA damage, marked by increased levels of ATM and H2AX phosphorylation, increased H3K56ac, and reduced SNF2H recruitment to chromatin. A significant increase in apoptotic cells in the cortex is observed, as determined by TUNEL staining in young mice (3-4 month old). SIRT6-deficient brains have increased signs of DNA damage and cell death. Behavioral defects of brS6KO mice, overview. SIRT6 deletion markedly decreases non-associative (OF) and associative (CFC) learning. SIRT6KO cells are more sensitive to apoptosis, prevented by GSK3 or ATM inhibition |

generation of SIRT6 knockout human mesenchymal stem cells (hMSCs) by targeted gene editing. For generation of SIRT6-deficient human embryonic stem cells (hESCs), the exon 1 of SIRT6 gene is removed in hESCs by a transcription activator-like effector nuclease. SIRT6-deficient hMSCs exhibit accelerated functional decay, a feature distinct from typical premature cellular senescence. Rather than compromised chromosomal stability, SIRT6-null hMSCs are predominately characterized by dysregulated redox metabolism and increased sensitivity to the oxidative stress. SIRT6 forms a protein complex with both nuclear factor erythroid 2-related factor 2 (NRF2) and RNA polymerase II, which is required for the transactivation of NRF2-regulated antioxidant genes, including heme oxygenase 1 (HO-1).
