Canagliflozin impairs T-cell effector function via metabolic suppression in autoimmunity [Metabolic Pathways]

ABSTRACT: Augmented T-cell function leading to host damage in autoimmunity is supported by metabolic dysregulation. Targeting immunometabolism for the treatment of autoimmunity by repurposing clinically approved metabolic modulators, such as those used to treat people with type 2 diabetes (T2D), is therefore an attractive avenue. Canagliflozin, a class of the newest type of T2D drug – sodium glucose co-transporter 2 (SGLT2) inhibitors – has known off-target effects including mitochondrial glutamate dehydrogenase (GDH) and complex I inhibition. To date, the effects of SGLT2 inhibitors on human T-cell function are extremely limited. Here, we analysed 748 genes using the Nanostring nCounter® Metabolic Pathways Panel and discovered 38 genes that were differentially regulated between canagliflozin-treated (cana, C; n = 6) and DMSO vehicle control (V; n = 6) T-cells. Of these genes, 24 were downregulated, whilst 14 were upregulated. Notably, 17 of the 24 genes that were downregulated following canagliflozin treatment were associated with the cell cycle, whilst SMAD3 was the only cell cycle-associated gene upregulated by canagliflozin. These analyses allowed a greater understanding of the global changes in T-cell metabolism that occur in response to treatment with SGLT2 inhibitors.

Canagliflozin impairs T-cell effector function via metabolic suppression in autoimmunity [Autoimmune Profiling]

Project description:Augmented T-cell function leading to host damage in autoimmunity is supported by metabolic dysregulation. Targeting immunometabolism for the treatment of autoimmunity by repurposing clinically approved metabolic modulators, such as those used to treat people with type 2 diabetes (T2D), is therefore an attractive avenue. Canagliflozin, a class of the newest type of T2D drug – sodium glucose co-transporter 2 (SGLT2) inhibitors – has known off-target effects including mitochondrial glutamate dehydrogenase (GDH) and complex I inhibition. To date, the effects of SGLT2 inhibitors on human T-cell function are extremely limited. Here, we analysed 784 genes using the Nanostring nCounter® Autoimmune Profiling Panel and discovered 42 genes that were differentially regulated between canagliflozin-treated (cana, C; n = 6) and DMSO vehicle control (V; n = 6) T-cells. Of these genes, 39 were downregulated, including IL2, CSF2 and CCL20; whilst 3 were upregulated, including SELL. Dapagliflozin was used as another control, as this SGLT2 inhibitor does not exhibit any known off-target effects like canagliflozin. Here, there were no differentially expressed genes between dapagliflozin-treated (dapa, D; n = 4) and DMSO vehicle control (V; n = 4) T-cells. These analyses allowed a greater understanding of the global changes in T-cell function that occur in response to treatment with SGLT2 inhibitors.

The effects of SGLT-2 inhibitors canagliflozin on hepatic transcription

Project description:We assessed the change in hepatic transciptional pattern after treatment with SGLT-2 inhibitors canagliflozin in a mice model of diet-induced obesity. Pharmacologic inhibition of the renal sodium/glucose cotransporter-2 induces glycosuria and reduces glycemia. Given that SGLT2 inhibitors (SGLT2i) reduce mortality and CV risk in T2D, improved understanding of molecular mechanisms mediating these metabolic effects is required. Treatment of obese but nondiabetic mice with the SGLT2i canagliflozin (CANA) reduces adiposity, improves glucose tolerance despite reduced plasma insulin, increases plasma ketones, and improves plasma lipid profiles. We utilized an integrated transcriptomic-metabolomics approach to demonstrate that CANA modulates key nutrient-sensing pathways, with activation of AMPK and inhibition of mTOR, independent of insulin or glucagon sensitivity or signaling. Moreover, CANA induces transcriptional reprogramming to activate catabolic pathways, increase fatty acid oxidation, reduce hepatic steatosis and diacylglycerol content, and increase hepatic and plasma levels of FGF21. Taken together, these data demonstrate that SGLT-2 inhibition triggers a fasting-like transcriptional and metabolic paradigm.

SGLT2 inhibitors and zebrafish

Project description:The CANVAS program revealed that the SGLT2 inhibitor canagliflozin increases the risk for lower-limb (minor) amputations in type 2 diabetics about a two-fold. On the contrary, the large RCTs with empagliflozin and dapagliflozin did not demonstrate a similar observation. Thus, a question arises whether the increased risk for minor amputations is associated only with canagliflozin or whether it is a class effect of SGLT2 inhibitors. Vascular disorders including defective angiogenesis are among the leading causes of lower-limb amputations. Therefore, here we examined the effects of empagliflozin, dapagliflozin, and canagliflozin on angiogenesis using zebrafish embryos and HUVECs.

Canagliflozin treatment prevents follicular exhaustion and attenuates hallmarks of ovarian aging in genetically heterogenous mice

Project description:Ovarian aging is characterized by declines in follicular reserve and the emergence of mitochondrial dysfunction, reactive oxygen species production, inflammation, and fibrosis, which eventually results in menopause. Menopause is associated with increased systemic aging and the development of numerous comorbidities; therefore, the attenuation of ovarian aging could also delay systemic aging processes in women. Recent work has established that the anti-diabetic drug Canagliflozin (Cana), a sodium-glucose transporter 2 inhibitor, elicits benefits on aging-related outcomes, likely through the modulation of nutrient-sensing pathways and metabolic homeostasis. Given that nutrient-sensing pathways play a critical role in controlling primordial follicle activation, we sought to determine if chronic Cana administration would delay ovarian aging and curtail the emergence of pathological hallmarks associated with reproductive senescence. We found that mice receiving Cana maintained their ovarian reserve through 12 months of age, which was associated with declines in primordial follicles FoxO3a phosphorylation, a marker of activation, when compared to the age-matched controls. Furthermore, Cana treatment led to decreased collagen, lipofuscin, and T cell accumulation at 12 months of age. Whole ovary transcriptomic and proteomic analyses revealed subtle improvements, predominantly in mitochondrial function and the regulation of cellular proliferation. Pathway analyses of the transcriptomic data revealed a downregulation in cell proliferation and mitochondrial dysfunction signatures, with an upregulation of oxidative phosphorylation. Pathway analyses of the proteomic data revealed declines in signatures associated with PI3K/AKT activity and lymphocyte accumulation. Collectively, we demonstrate that Cana treatment can delay ovarian aging in mice and could potentially have efficacy for delaying ovarian aging in women.

Glucose deprivation promotes lung adenocarcinoma de-differentiation due to unbalanced EZH2 activity

Project description:Lung cancer is the most frequent cancer-related cause of death, and adenocarcinoma (LUAD) is the most frequent type. Despite the recent success of immunotherapies, survival of lung cancer patients has not significantly improved in the last decades. New therapies are necessary. We have previously identified sodium-glucose transporter 2 (SGLT2) as the major responsible for glucose uptake in LUAD, and we have showed that treatment with SGLT2 inhibitors significantly delays LUAD development and prolongs survival in murine models. However, our data shows that SGLT2 inhibitors also induce de-differentiation of LUAD cells, leading to a more aggressive phenotype and increased resistance to cisplatin. Glucose deprivation causes reduced αKG levels, leading to reduced activity of αKG-dependent histone demethylases and consequent histone hypermethylation. Supplementation of αKG or inhibition of the histone methyltransferase EZH2 reverse this phenotype, suggesting that this de-differentiated phenotype depends on insufficiency of αKG-dependent histone demethylases and unbalanced EZH2 activity. Consistently, double treatment with an SGLT2 inhibitor and an EZH2 inhibitor significantly reduces the tumor burden in a genetically engineered murine model of LUAD. We further characterized the effect of low glucose-induced tumor de-differentiation, identifying stabilization of hypoxia inducible factor 1α (HIF1α) as a major pathway responsible for the acquisition of a more aggressive phenotype following glucose deprivation. Finally, we identified an HIF1α-dependent transcriptional signature with prognostic significance in human LUAD. Our studies further our knowledge of the relationship between glucose metabolism and cell differentiation in cancer, characterizing the epigenetic adaptation of cancer cells to nutrient deprivation and identifying novel targets to prevent the development of resistance to metabolic therapies.
