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.

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.

Project description:Background and aims: There are considerable evidences demonstrating that angiogenesis and chronic inflammation are mutually dependent. However, although cirrhosis progression is characterized with a chronic hepatic inflammatory process, this connection is not sufficiently explored as a therapeutic strategy. Therefore, this study was aimed to assess the potential benefits of targeting angiogenesis in cirrhotic livers to modulate inflammation and fibrosis. For this purpose, we evaluate the therapeutic utility of angiogenesis inhibitors. Methods: The in vivo effects of angiogenesis inhibitors were monitored in liver of cirrhotic rats by measuring angiogenesis, inflammatory infiltrate, fibrosis, a-smooth muscle actin (a-SMA) accumulation, differential gene expression (by microarrays), and portal pressure. Results: Cirrhosis progression was associated with a significant enhancement of vascular density and expression of vascular endothelial growth factor-A (VEGF-A), angiopoietin-1, angiopoietin-2 and placental growth factor (PlGF) in cirrhotic livers. The newly formed hepatic vasculature expressed vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1). Interestingly, the expression of these adhesion molecules correlated well with local inflammatory infiltrate. Livers of cirrhotic rats treated with angiogenesis inhibitors presented a significant decrease in hepatic vascular density, inflammatory infiltrate, a-SMA abundance, collagen expression and portal pressure. Conclusion: Angiogenesis inhibitors may offer a potential novel therapy for cirrhosis due to its multiple mechanisms of action against angiogenesis, inflammation and fibrosis in cirrhotic livers. Experiment Overall Design: RNA from liver of 4 non-treated cirrhotic rats or 4 rats treated with angiogenesis inhibitors was hybridized to 8 high-density oligonucleotide microarray (Rat2302, Affymetrix, Santa Clara, CA)

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 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.

Project description:Non-small cell lung cancer (NSCLC) has a poor prognosis and effective therapeutic strategies are lacking. The diabetes drug canagliflozin inhibits NSCLC cell proliferation and the mammalian target of rapamycin (mTOR) pathway, which mediates cell growth and survival, but it is unclear whether this drug can enhance response rates when combined with cytotoxic therapy. Here, we evaluated the effects of canagliflozin on human NSCLC response to cytotoxic therapy in tissue cultures and xenografts. Ribonucleic acid sequencing (RNA-seq), real-time quantitative PCR (RT-qPCR), metabolic function, small interfering ribonucleic acid (siRNA) knockdown and protein expression assays were used in mechanistic analyses. We found that canagliflozin inhibited proliferation and clonogenic survival of NSCLC cells, and augmented the efficacy of radiotherapy to mediate these effects and inhibit NSCLC xenograft growth. Canagliflozin treatment alone moderately inhibited mitochondrial oxidative phosphorylation and exhibited greater anti-proliferative capacity than specific mitochondrial complex-I inhibitors. The treament downregulated genes mediating hypoxia-inducible factor (HIF)-1a stability, metabolism and survival, activated adenosine monophosphate-activated protein kinase (AMPK) and inhibited mTOR, a critical activator of HIF-1a signaling. HIF-1a knockdown and stabilization experiments suggested that canagliflozin mediates anti-proliferative effects, in part, through suppression of HIF-1a. Transcriptional regulatory network analysis pinpointed histone deacetylase 2 (HDAC2), a gene suppressed by canagliflozin, as a key mediator of canagliflozin’s transcriptional reprogramming. HDAC2 knockdown eliminated HIF-1a levels and enhanced the anti-proliferative effects of canagliflozin. HDAC2-regulated genes suppressed by canagliflozin are associated with poor prognosis in several clinical NSCLC datasets. In addition, we include evidence that canagliflozin also improves NSCLC response to chemotherapy. In summary, canagliflozin may be a promising therapy to develop in combination with cytotoxic therapy in NSCLC.

Project description:Temporally restricted feeding has a profound effect on the circadian clock. Fasting and feeding paradigms are known to influence hepatic transcription. This dataset shows the dynamic effects of refeeding mice after a 24hour fasting period. Mice were entrained for two weeks under ad libitum access to food. Mice were then released into constant darkness and food was withdrawn at CT4 on the first day in constant darkness. On the second day in constant darkness mice were either fed (Refed) or continously fasted (Fast) at CT4. Liver tissue was collected at the indicated timepoints. Total RNA was extracted and standard Affymetrix protocol were used for amplification, labeling and hybridization
