SGLT1 in pancreatic α cells regulates glucagon secretion in mice, possibly explaining the distinct effects of SGLT2 inhibitors on plasma glucagon levels
ConclusionsThese data suggested that a novel mechanism regulated glucagon secretion through SGLT1 in α cells. This finding possibly explained the distinct effects of dapagliflozin and canagliflozin on plasma glucagon levels in mice.

GSE106180 Stable oxidative cytosine modifications accumulate in cardiac mesenchymal cells from Type2 diabetes patients: rescue by alpha-ketoglutarate and TET-TDG functional reactivation mouse heart RNA-seq
Conclusions: In this report we established that diabetes may epigenetically modify and compromise function of the rapeutically relevant cardiac mesenchymal cells. Restoring the epi-metabolic control of DNA demethylation cycle promises beneficial effects on cells compromised by environmental metabolic changes.

Repin1 deficiency in liver tissue alleviates NAFLD progression in mice
This study provides evidence that loss of Repin1 in the liver attenuates NAFLD progression, most likely by reducing fat accumulation and alleviating chronic tissue inflammation. Thus, modulating Repin1 expression may become a novel strategy and potential tool to inhibit NAFLD progression.Graphical abstract

Resveratrol Ameliorates Lipid Droplet Accumulation in Liver Through a SIRT1/ ATF6-Dependent Mechanism
Conclusion: Taken together, these findings indicate that RSV supplementation improves hepatic steatosis by ameliorating the accumulation of LDs, and this might be partially mediated by a SIRT1/ATF6-dependent mechanism.Cell Physiol Biochem 2018;51:2397 –2420

The role of the BMP4/Smad1 signaling pathway in mesangial cell proliferation: A possible mechanism of diabetic nephropathy
This study explored the role of the BMP4/Smad1 signaling pathway in mesangial matrix expansion during the process of diabetic nephropathy.Main methodsDiabetic rats were induced by high-fat feeding followed by an intraperitoneal injection of streptozotocin. Glomerular lesions were examined. Immunohistochemical analysis was performed in order to identify BMP4/Smad1 signaling proteins (BMP4, ALK3, and Smad1) and mesangial ECM proteins (Col1 and Col4) in kidney tissue. Cell proliferation and the expression of BMP4, Smad1 and Col4 were determined in cultured mesangial cells exposed to high glucose. The specific regulatory role ...

FGF21 as Modulator of Metabolism in Health and Disease
In conclusion, FGF21 belongs to a promising class of cytokines that are induced in response to stress and that can be used as a drug, drug target, or through a biomarker, depending on the physio-pathological context. All these findings will become clear when FGF21 will be used as a therapeutic molecule, exploiting the beneficial effects of FGF21 for treating metabolic disease or when it will be blocked to ameliorate disease progression and the onset of disease. Author Contributions CT and MS wrote the manuscript. VR contributed to the discussion. Funding This work was supported from the AFM-Telethon (19524), Italian Mi...

Pro-atherogenic proteoglycanase ADAMTS-1 is down-regulated by lauric acid through PI3K and JNK signaling pathways in THP-1 derived macrophages.
Abstract The prevalence of atherosclerosis has increased significantly in the recent years due to sedentary lifestyle and high-fat diet. However, the association between saturated fat intake and the increased risk for atherosclerotic cardiovascular diseases remains heavily debated. Lauric acid belongs to the saturated fatty acid group and its unique medium chain fatty acid properties are proven to be beneficial to humans in many ways. Thus, the aim of this project is to investigate the effect of lauric acid on the expression of a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) genes-ADAMTS-1,...

Parthenolide, a feverfew-derived phytochemical, ameliorates obesity and obesity-induced inflammatory responses via the Nrf2/Keap1 pathway
Publication date: Available online 9 May 2019Source: Pharmacological ResearchAuthor(s): Chae Young Kim, Bobin Kang, Hyung Joo Suh, Hyeon-Son ChoiAbstractParthenolide (PL) is one of the most abundant sesquiterpene lactones found in the plant feverfew (Tanacetum parthenium (L.) Sch.Bip.). PL was investigated for its effect on obesity and obesity-induced inflammatory/oxidant responses in vitro and in vivo. An obesity-induced inflammatory response was induced in various co-culture systems using adipocytes (3T3-L1) and macrophages (RAW264.7) in vitro and the effect of PL and its mechanism of action were determined. PL effective...

CYP3A suppression during diet-induced nonalcoholic fatty liver disease is independent of PXR regulation
Publication date: Available online 24 May 2019Source: Chemico-Biological InteractionsAuthor(s): Hang Zeng, Yiming Lin, Jiande Gong, Sisi Lin, Jianguo Gao, Chunxiao Li, Zemin Feng, Hong Zhang, Jie Zhang, Youming Li, Chaohui YuAbstractCytochrome P450 3A (CYP3A) activity is inhibited, and its expression is suppressed during many diseases, including nonalcoholic fatty liver disease (NAFLD). However, the mechanism is controversial. Here, we report that PXR may not take part in the downregulation of CYP3A during NAFLD. Hepatic CYP3A11 (major subtype of mouse CYP3A) mRNA and protein expression was significantly decreased in both ...

Carbonic Anhydrase 1-Mediated Calcification Is Associated With Atherosclerosis, and Methazolamide Alleviates Its Pathogenesis
Vascular calcification is an important pathogenic process in atherosclerosis (AS); however, its immediate cause is unknown. Our previous study demonstrated that carbonic anhydrase 1 (CA1) stimulates ossification and calcification in ankylosing spondylitis and breast cancer. The current study investigated whether CA1 plays an important role in AS calcification and whether the CA inhibitor methazolamide (MTZ) has a therapeutic effect on AS. We successfully established an AS model by administration of a high-fat diet to ApoE-/- mice. The treated animals had significantly increased serum levels of high-density lipoprotein chol...

CYP3A suppression during diet-induced nonalcoholic fatty liver disease is independent of PXR regulation.
Abstract Cytochrome P450 3A (CYP3A) activity is inhibited, and its expression is suppressed during many diseases, including nonalcoholic fatty liver disease (NAFLD). However, the mechanism is controversial. Here, we report that PXR may not take part in the downregulation of CYP3A during NAFLD. Hepatic CYP3A11 (major subtype of mouse CYP3A) mRNA and protein expression was significantly decreased in both mice fed a high-fat diet (HFD) for 8 weeks and palmitate (PA)-treated mouse primary hepatocytes. Similarly, in HepG2 cells, PA treatment significantly suppressed the CYP3A4 (major subtype of human CYP3A) mRNA level ...

Hydrogen sulfide regulates circadian-clock genes in C2C12 myotubes and the muscle of high-fat-diet-fed mice.
We examined whether H2S has any effect on CCG in the skeletal muscle of mice fed a high-fat diet (HFD) and in myotubes. In the muscle of HFD-mice, the expression of H2S biosynthesis enzyme genes (CSE, CBS, and 3-Mpst) along with antioxidant genes (GCLC, GCLM, GSS, and GSR) involved in GSH biosynthesis and recycling were reduced significantly, but the oxidative stress (OS) increased. Expression of the CCG (Bmal1, Clock, RORα, Cry2, Per2) and clock-controlled genes (PPARγ, PGC-1α, RXRα) was downregulated, whereas the levels of PPARα mRNA were upregulated. Similar to that in the muscle of HFD-mice, in vitro myotubes expo...

Physiological roles of the GIP receptor in murine brown adipose tissue
ConclusionsThe BAT GIPR is linked to the control of metabolic gene expression, fuel utilization, and oxygen consumption. However, the selective loss of the GIPR within BAT is insufficient to recapitulate the findings of decreased weight gain and resistance to obesity arising in experimental models with systemic disruption of GIP action.Graphical abstract
