Mitochondria ROS and mitophagy in acute kidney injury.Mitophagy is an essential mitochondrial quality control mechanism that eliminates damaged mitochondria and the production of reactive oxygen species (ROS). The relationship between mitochondria oxidative stress, ROS production and mitophagy are intimately interwoven, and these processes are all involved in various pathological conditions of acute kidney injury (AKI). The elimination of damaged mitochondria through mitophagy in mammals is a complicated process which involves several pathways. Furthermore, the interplay between mitophagy and different types of cell death, such as apoptosis, pyroptosis and ferroptosis in kidney injury is unclear. Here we will review recent advances in our understanding of the relationship between ROS and mitophagy, the different mitophagy pathways, the relationship between mitophagy and cell death, and the relevance of these processes in the pathogenesis of AKI.

Relaxin has beneficial effects on liver lipidome and metabolic enzymes.Relaxin is an insulin-like hormone with pleiotropic protective effects in several organs, including the liver. We aimed to characterize its role in the control of hepatic metabolism in healthy rats. Sprague-Dawley rats were treated with human recombinant relaxin-2 for 2Â weeks. The hepatic metabolic profile was analyzed using UHPLC-MS platforms. Hepatic gene expression of key enzymes of desaturation (Fads1/Fads2) of n-6 and n-3 polyunsaturated fatty acids (PUFAs), of phosphatidylethanolamine (PE) N-methyltransferase (Pemt), of fatty acid translocase Cd36, and of glucose-6-phosphate isomerase (Gpi) were quantified by Real Time-PCR. Activation of 5'AMP-activated protein kinase (AMPK) was analyzed by Western Blot. Relaxin-2 significantly modified the hepatic levels of 19 glycerophospholipids, 2 saturated (SFA) and 1 monounsaturated (MUFA) fatty acids (FA), 3 diglycerides, 1 sphingomyelin, 2 aminoacids, 5 nucleosides, 2 nucleotides, 1 carboxylic acid, 1 redox electron carrier, and 1 vitamin. The most noteworthy changes corresponded to the substantially decreased lysoglycerophospholipids, and to the clearly increased FA (16:1n-7/16:0) and MUFA + PUFA/SFA ratios, suggesting enhanced desaturase activity. Hepatic gene expression of Fads1, Fads2, and Pemt, which mediates lipid balance and liver health, was increased by relaxin-2, while mRNA levels of the main regulator of hepatic FA uptake Cd36, and of the essential glycolysis enzyme Gpi, were decreased. Relaxin-2 augmented the hepatic activation of the hepatoprotector and master regulator of energy homeostasis AMPK. Relaxin-2 treatment also rised FADS1, FADS2, and PEMT gene expression in cultured Hep G2 cells. Our results bring to light the hepatic metabolic features stimulated by relaxin, a promising hepatoprotective molecule.

Periodontal Manifestation of Type Ib Glycogen Storage Disease: A Rare Case Report.Glycogen storage diseases (GSD) are genetic metabolic disorders of glycogen metabolism. There are >15 types based on the enzyme deficiency and the affected organ. Glycogen storage disease Type Ib is the only type associated with neutropenia and periodontitis. This type is caused by a deficiency of glucose-6-phosphate (G6P) translocase which prevents the transport of G6P across the endoplasmic reticulum. As a result, glycogen cannot be metabolized into glucose with its subsequent accumulation in tissues. The affected organs involved in Type Ib are the liver, kidney, and intestine.

The Metabolic Effects of Supplementation in Overweight and Obese Class I Subjects with Newly Detected Impaired Fasting Glycemia: A Double-Blind, Placebo-Controlled, Randomized Clinical Trial.Impaired fasting glucose (IFG) is a condition that precedes diabetes and increases the risk of developing it. Studies support the hypoglycemic effect of (Cs) extracts due to the content of chlorogenic acid, which is a potent inhibitor of glucose 6-phosphate translocase and of dicaffeoylquinic acid derivatives that modulate the activity of alpha-glucosidase. Given this background, we investigated whether a new highly standardized Cs extract could improve glycemic control, insulin sensitivity and other metabolic parameters (total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C) Triglycerides, Apolipo protein B (ApoB), Apolipo protein A (ApoA), waist circumference, visceral adipose tissue (VAT) by dual-energy X-ray absorptiometry (DXA) in overweight subjects with newly diagnosed IFG. Fifty-four subjects (females/males 26/28, mean Â± SD age 51.5 Â± 6.2) were randomly assigned to the supplemented group ( = 27) and placebo ( = 27). After multiple testing correction, statistically significant interactions between time and group were observed for the primary endpoint glycemia (Î² = 0.36, < 0.0001) and for the secondary endpoints HDL (Î² = -0.10, < 0.0001), total cholesterol/HDL (Î² = 0.27, < 0.0001), LDL (Î² = 0.15, = 0.005), LDL/HDL (Î² = 0.23, = 0.001), insulin (Î² = 1.28, = 0.04), glycated hemoglobin (Î² = 0.21, = 0.0002), A1c-derived average glucose (Î² = 0.34, = 0.0002), ApoB (Î² = 6.00, = 0.01), ApoA (Î² = -4.50, = 0.04), ApoB/ApoA (Î² = 0.08, = 0.003), waist circumference (Î² = 1.89, = 0.05), VATÎ² = 222.37, = 0.005). In conclusion, these results confirm that Cs supplementation has a significant effect on metabolic parameters in IFG patients.

Longterm Outcomes of Living Donor Liver Transplantation for Glycogen Storage Disease Type 1b.Glycogen storage disease (GSD) type 1b (Online Mendelian Inheritance in Man [OMIM] 232220) is an autosomal recessive inborn error of carbohydrate metabolism caused by defects in glucose-6-phosphate translocase. GSD1b patients have severe hypoglycemia with several clinical manifestations of hepatomegaly, obesity, a doll-like face, and neutropenia. Liver transplantation (LT) has been indicated for severe glucose intolerance, poor metabolic control (PMC), and poor growth (PG). We retrospectively reviewed 11 children with GSD1b who underwent living donor liver transplantation (LDLT) at the National Center for Child Health and Development in Tokyo, Japan. Between November 2005 and December 2018, 495 children underwent LDLT with an overall 10-year patient and graft survival of 90.6% and 88.9%, respectively. Of these, LT was indicated for 11 patients with GSD1b. All patients are doing well with the stabilization of glucose intolerance and decreased hospitalization for infectious complications. Demand for granulocyte colony-stimulating factor significantly decreased. However, although LT stabilized the blood glucose level, the platelet function was not improved. The posttransplant developmental quotient (DQ) remained similar to the pretransplant DQ without deterioration. LDLT is a feasible procedure for GSD1b patients with regard to the longterm prognosis. LT should be considered for patients with severe glucose intolerance to protect the cognitive function against hypoglycemic encephalopathy and to ameliorate PMC and PG.

Molecular diagnosis of glycogen storage disease type I: a review.Glycogen storage disease type I (GSD I) is a relatively rare metabolic disease with variable clinical intensity. It is caused by deficient activity of the glucose 6-phosphatase enzyme (GSD Ia) or a deficiency in the microsomal transport proteins for glucose 6-phosphate (GSD Ib). We searched the most recent English literature (1997-2017) regarding any article with the key word of "glycogen storage disease type I" in PubMed, Science Direct, Scopus, EMBASE, and Google Scholar. We will present all of the published articles about the molecular genetic characteristics and old-to-new diagnostic methods used to identify GSD I in regard of methodology, advantages and disadvantages. Diagnosis of GSD type I and its variants is challenging because it is a genetically heterogeneous disorder. Many molecular methods have been used to diagnose GSD I most of which have been based on mutation detection. Therefore, we discuss complete aspects of all of the molecular diagnostic tests, which have been used in GSD type I so far. With the advent of high throughput advanced molecular tests, molecular diagnosis is going to be an important platform for the diagnosis of storage and metabolic diseases such as GSD type I. Next-generation sequencing, in combination with the biochemical tests and clinical signs and symptoms create an accurate, reliable and feasible method. It can overcome the difficulties by the diagnosis of diseases with broad clinical and genetic heterogeneity.

The Physiopathological Role of the Exchangers Belonging to the SLC37 Family.The human gene family includes four proteins SLC37A1-4, localized in the endoplasmic reticulum (ER) membrane. They have been grouped into the SLC37 family due to their sequence homology to the bacterial organophosphate/phosphate (Pi) antiporter. SLC37A1-3 are the less characterized isoforms. SLC37A1 and SLC37A2 are Pi-linked glucose-6-phosphate (G6P) antiporters, catalyzing both homologous (Pi/Pi) and heterologous (G6P/Pi) exchanges, whereas SLC37A3 transport properties remain to be clarified. Furthermore, SLC37A1 is highly homologous to the bacterial glycerol 3-phosphate permeases, so it is supposed to transport also glycerol-3-phosphate. The physiological role of SLC37A1-3 is yet to be further investigated. SLC37A1 seems to be required for lipid biosynthesis in cancer cell lines, has been proposed as a vitamin D and a phospho-progesterone receptor target gene, while mutations in the gene appear to be associated with congenital hyperinsulinism of infancy. SLC37A4, also known as glucose-6-phosphate translocase (G6PT), transports G6P from the cytoplasm into the ER lumen, working in complex with either glucose-6-phosphatase-Î± (G6Pase-Î±) or G6Pase-Î² to hydrolyze intraluminal G6P to Pi and glucose. G6PT and G6Pase-Î² are ubiquitously expressed, whereas G6Pase-Î± is specifically expressed in the liver, kidney and intestine. G6PT/G6Pase-Î± complex activity regulates fasting blood glucose levels, whereas G6PT/G6Pase-Î² is required for neutrophil functions. G6PT deficiency is responsible for glycogen storage disease type Ib (GSD-Ib), an autosomal recessive disorder associated with both defective metabolic and myeloid phenotypes. Several kinds of mutations have been identified in the gene, affecting G6PT function. An increased autoimmunity risk for GSD-Ib patients has also been reported, moreover, SLC37A4 seems to be involved in autophagy.
