Obesity-related insulin resistance is closely associated with macrophage accumulation and subsequent cytokine release in local tissues. Sirtuin 6 (Sirt6) is known to exert an anti-inflammatory function, but its role in macrophages in the context of obesity has not been investigated. We generated myeloid-specific Sirt6 knockout (mS6KO) mice and investigated the metabolic characteristics after high-fat diet (HFD) feeding for 16 weeks. Compared with their wild-type littermates, HFD-fed mS6KO mice… 

Figures from this paper

Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans
TLDR
It is suggested that adipocyte Sirt 6 regulates body weight gain and insulin sensitivity independent of diet, and the increased IL-4 production by Sirt6 and resultant M2 polarization of adipose tissue macrophages may attenuate proinflammatory responses in adipOSE tissue.
Fpr2 Deficiency Alleviates Diet-Induced Insulin Resistance Through Reducing Body Weight Gain and Inhibiting Inflammation Mediated by Macrophage Chemotaxis and M1 Polarization
TLDR
It is demonstrated that myeloid Fpr2 plays critical roles in obesity and related metabolic disorders via regulating muscle energy expenditure, macrophage chemotaxis, and M1 polarization.
Role of Arginase 2 in Systemic Metabolic Activity and Adipose Tissue Fatty Acid Metabolism in Diet-Induced Obese Mice
TLDR
A2 deletion prevented HFHS-induced VAT collagen deposition and inflammation, which are involved in adipocyte metabolic dysfunction, which is involved in obesity-associated metabolic and vascular disorders.
Retinoic acid induced 16 deficiency exacerbates high-fat diet-induced steatohepatitis in mice.
TLDR
It is indicated that RAI16 plays an important role in HFD-induced liver pathology and might be considered as a target for treatment of NAFLD.
Loss of Sirt6 in adipocytes impairs the ability of adipose tissue to adapt to intermittent fasting
TLDR
It is indicated that Sirt 6 in adipocytes is critical to obtaining the improved glucose metabolism and metabolic profiles conferred by IF and that maintaining high levels of Sirt6 in adipocyte may mimic the health benefits of IF.
Epigallocatechin-3-Gallate-Rich Green Tea Extract Ameliorates Fatty Liver and Weight Gain in Mice Fed a High Fat Diet by Activating the Sirtuin 1 and AMP Activating Protein Kinase Pathway.
TLDR
The possible therapeutic potential of dietary epigallocatechin gallate-rich GTE supplementation for preventing the development and progression of hepatic steatosis and obesity is suggested.
P53/PANK1/miR‐107 signalling pathway spans the gap between metabolic reprogramming and insulin resistance induced by high‐fat diet
TLDR
Results revealing a new mechanism by which P53 regulate metabolism and the different roles of PANK1 and its intron miR‐107 in metabolic regulation, which will provide more accurate intervention targets for the treatment of metabolic diseases.
Myeloid cell-specific sirtuin 6 deficiency delays wound healing in mice by modulating inflammation and macrophage phenotypes
TLDR
Wound closure was delayed in the KO mice, which exhibited less collagen deposition, suppressed angiogenesis, and reduced expression of wound healing-related genes compared to the wild-type mice, and impaired wound healing was suggested.

Myeloid SIRT1 regulates macrophage infiltration and insulin sensitivity in mice fed a high-fat diet.
TLDR
The results indicate that myeloid SIRT1 plays a crucial role in macrophage polarization and chemotaxis, and thus regulates the development of HFD-induced pancreatic inflammation and insulin secretion, and metabolic derangements in liver and adipose tissue.
Kupffer cell activation is a causal factor for hepatic insulin resistance.
TLDR
It is demonstrated that selective Kupffer cell depletion obtained by intravenous clodronate was sufficient to enhance insulin-dependent insulin signaling and significantly improve hepatic insulin sensitivity in vivo in this short-term high-fat diet model.
Obesity induces a phenotypic switch in adipose tissue macrophage polarization.
TLDR
Diet-induced obesity leads to a shift in the activation state of ATMs from an M2-polarized state in lean animals that may protect adipocytes from inflammation to an M1 proinflammatory state that contributes to insulin resistance.
SIRT6 protects against pathological damage caused by diet‐induced obesity
TLDR
Gene expression analysis of adipose tissue revealed that the positive effect of SIRT6 overexpression is associated with down regulation of a selective set of peroxisome proliferator‐activated receptor‐responsive genes, and genes associated with lipid storage, which were suggested as potential targets for drugs to control metabolic syndrome.
Obesity is associated with macrophage accumulation in adipose tissue.
TLDR
Transcript expression in perigonadal adipose tissue from groups of mice in which adiposity varied due to sex, diet, and the obesity-related mutations agouti (Ay) and obese (Lepob) found that the expression of 1,304 transcripts correlated significantly with body mass.
Myeloid Deletion of SIRT1 Induces Inflammatory Signaling in Response to Environmental Stress
TLDR
It is reported that SIRT1, in macrophages, functions to inhibit NF-κB-mediated transcription, implying that myeloid cell-specific modulation of this sirtuin may be beneficial in the treatment of inflammation and its associated diseases.
Kupffer cells promote hepatic steatosis via interleukin‐1β–dependent suppression of peroxisome proliferator‐activated receptor α activity
TLDR
The data point toward important cross‐talk between Kupffer cells and hepatocytes in the regulation of hepatic triglyceride storage, which is at least partially mediated by IL‐1β, which suppresses PPARα expression and activity.
Progression of Chronic Liver Inflammation and Fibrosis Driven by Activation of c-JUN Signaling in Sirt6 Mutant Mice*
TLDR
Sirt6 plays an anti-inflammatory role in mice by inhibiting c-JUN-dependent expression of proinflammatory genes, suggesting that Sirt6 deficiency in the immune cells is the cause of chronic liver inflammation.
