EE is caused by mutations in ethylmalonic encephalopathy protein 1 (ETHE1), and more than 60 different mutations have been reported.1,2 ETHE1 encodes a mitochondrial sulfur dioxygenase involved in the catabolism of hydrogen sulfide 2 fi (H2S). Impairment of sulfur dioxygenase leads to the accumulation of hydrogen sul de and its fl derivatives (thiosulphate) in various body uids and tissues. Higher concentration of H2Sistoxic and induces direct damage to cell membranes. It inhibits cytochrome c oxidase (COX), increases lactic acid and short-chain acyl-COA dehydrogenase, and leads to elevation of ethyl malonate and C4/C5 acylcarnitine in muscle and brain.2 We describe the clinical phenotype and MRI, path- ologic, and biochemical findings of a patient with EE from India who had a novel homozygous c.493 G>C (p.D165H) variation in ETHE1.

In the past, it has been investigated for its role as a potent toxic gas emanating from sewers and swamps or as a by-product of industrial processes. At high concentrations, H2S is a powerful inhibitor of cytochrome c oxidase; in trace amounts, it is an important signaling molecule, like nitric oxide (NO) and carbon monoxide (CO), together termed “gasotransmitters.” This review will cover the physiological role and the pathogenic effects of H2S, focusing on ethylmalonic encephalopathy, a human mitochondrial disorder caused by genetic abnormalities of sulfide metabolism. We will also discuss the options that are now conceivable for preventing genetically driven chronic H2S toxicity, taking into account that a complete understanding of the physiopathology of H2S has still to be achieved. ecause of its fame as a deadly gas, the phys- 4.2.1.22) and cystathionine g-lyase (CSE, EC Biological role of H2S had been long over- 4.4.1.1), which both utilize L-cysteine as a sub- looked, until Abe and Kimura in 1996 (Abe strate (Stipanuk and Beck 1982; Hosoki et al.

Ethylmalonic Encephalopathy
Ethylmalonic encephalopathy Description Ethylmalonic encephalopathy is an inherited disorder that affects several body systems, particularly the nervous system. Neurological signs and symptoms include delayed development and the loss of previously acquired skills (developmental regression), weak muscle tone (hypotonia), seizures, and abnormal movements. The body's network of blood vessels (the vascular system) is also affected. Children with this disorder often develop rashes of tiny red spots (petechiae) caused by bleeding under the skin and blue discoloration in the hands and feet due to reduced oxygen in the blood (acrocyanosis). Chronic diarrhea is another common feature of ethylmalonic encephalopathy. The signs and symptoms of ethylmalonic encephalopathy are apparent at birth or begin in the first few months of life. Problems with the nervous system typically worsen over time, and most affected individuals survive only into early childhood. Frequency About 70 individuals with this condition have been identified worldwide, mostly in Mediterranean and Arab populations. Although ethylmalonic encephalopathy appears to be very rare, researchers suggest that some cases have been misdiagnosed as other neurological disorders. Causes Ethylmalonic encephalopathy results from mutations in the ETHE1 gene. This gene provides instructions for making an enzyme that is active in mitochondria, which are the energy-producing centers in cells. The ETHE1 enzyme is part of a pathway that breaks down sulfide (H2S), a molecule that is critical at very low levels for normal cell functioning but is toxic at high levels. Excess sulfide interferes with numerous cell activities, including mitochondrial energy production. Mutations in the ETHE1 gene lead to the production of a nonfunctional version of the enzyme or prevent any enzyme from being made.

Further Dissection of Qtls for Salt-Induced Stroke And
www.nature.com/scientificreports OPEN Further dissection of QTLs for salt- induced stroke and identifcation of candidate genes in the stroke-prone Received: 2 February 2018 Accepted: 5 June 2018 spontaneously hypertensive rat Published: xx xx xxxx Kaoru Niiya1, Hiroki Ohara1, Masato Isono 3, Abdullah Md. Sheikh2, Hiroyuki Matsuo1, Koichi Fujikawa1, Minoru Isomura4, Norihiro Kato3 & Toru Nabika1 We previously revealed that two major quantitative trait loci (QTLs) for stroke latency of the stroke- prone spontaneously hypertensive rat (SHRSP) under salt-loading were located on chromosome (Chr) 1 and 18. Here, we attempted further dissection of the stroke-QTLs using multiple congenic strains between SHRSP and a stroke-resistant hypertensive rat (SHR). Cox hazard model among subcongenic strains harboring a chromosomal fragment of Chr-1 QTL region showed that the most promising region was a 2.1 Mbp fragment between D1Rat177 and D1Rat97. The QTL region on Chr 18 could not be narrowed down by the analysis, which may be due to multiple QTLs in this region. Nonsynonymous sequence variations were found in four genes (Cblc, Cxcl17, Cic, and Ceacam 19) on the 2.1 Mbp fragment of Chr-1 QTL by whole-genome sequence analysis of SHRSP/Izm and SHR/Izm. Signifcant changes in protein structure were predicted in CBL-C and CXCL17 using I-TASSER. Comprehensive gene expression analysis in the kidney with a cDNA microarray identifed three candidate genes (LOC102548695 (Zinc fnger protein 45-like, Zfp45L), Ethe1, and Cxcl17). In conclusion, we successfully narrowed down the QTL region on Chr 1, and identifed six candidate genes in this region.

Insufficient dietary intake of riboflavin is often reported in nutritional surveys and population studies, even in non-developing countries with abundant sources of riboflavin-rich dietary products. A latent subclinical riboflavin deficiency can result in a significant clinical phenotype when combined with inborn genetic disturbances or environmental and physiological factors like infections, exercise, diet, aging and pregnancy. Riboflavin, and more importantly its derivatives, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), play a crucial role in essential cellular processes including mitochondrial energy metabolism, stress responses, vitamin and cofactor biogenesis, where they function as cofactors to ensure the catalytic activity and folding/stability of flavoenzymes. Numerous inborn errors of flavin metabolism and flavoenzyme function have been described, and supplementation with riboflavin has in many cases been shown to be lifesaving or to mitigate symptoms.

The Response of Sulfur Dioxygenase to Sulfide in the Body Wall of Urechis Unincinctus
The response of sulfur dioxygenase to sulfide in the body wall of Urechis unincinctus Litao Zhang1,2 and Zhifeng Zhang2 1 School of Biological Science, Jining Medical University, Rizhao, China 2 Key Laboratory of Marine Genetics and Breeding, Ministry of Education, Ocean University of China, Qingdao, China ABSTRACT Background. In some sedimentary environments, such as coastal intertidal and subtidal mudflats, sulfide levels can reach millimolar concentrations (2–5 mM) and can be toxic to marine species. Interestingly, some organisms have evolved biochemical strategies to overcome and tolerate high sulfide conditions, such as the echiuran worm, Urechis unicinctus. Mitochondrial sulfide oxidation is important for detoxification, in which sulfur dioxygenase (SDO) plays an indispensable role. Meanwhile, the body wall of the surface of the worm is in direct contact with sulfide. In our study, we chose the body wall to explore the SDO response to sulfide. Methods. Two sulfide treatment groups (50 mM and 150 mM) and a control group (natural seawater) were used. The worms, U. unicinctus, were collected from the intertidal flat of Yantai, China, and temporarily reared in aerated seawater for three days without feeding. Finally, sixty worms with similar length and mass were evenly assigned to the three groups. The worms were sampled at 0, 6, 24, 48 and 72 h after initiation of sulfide exposure. The body walls were excised, frozen in liquid nitrogen and stored at −80 ◦C for RNA and protein extraction. Real-time quantitative RT- PCR, enzyme-linked immunosorbent assay and specific activity detection were used to explore the SDO response to sulfide in the body wall.
