In this study, we investigated whether liver protein expression was altered after propofol, sevoflurane, or isoflurane anesthesia. We also investigated differences in the time course of each drug 24 and 72 h after anesthesia. Methods: Rats were randomly assigned to four groups (non-anesthetized group and three groups anesthetized at each time point, n = 6 per group). A venous catheter was inserted into the caudal vein of all rats. Rats were anesthetized with each agent for 6 h, and the liver was obtained immediately after anesthesia. Proteomic analysis was performed. Results: About 4200 spots in each gel were discriminated, and at least 2619 spots were matched. Using LC-MS/MS, we identified 47 spots for propofol, 45 spots for sevoflurane, and 21 spots for isoflurane that were differentially expressed (p < 0.05) 0 h after anesthesia. The numbers of altered proteins were 14 and 19 in the isoflurane and sevoflurane groups, respectively, 72 h after anesthesia, but alterations in 40 proteins were seen in the propofol group 72 h after anesthesia. -

Results: Upon 168 patients whose expression level of ALDH1 family members were available. We found that the level of ALDH1A1correlated to the prognosis of AML by the National Comprehensive Cancer Network (NCCN) stratification but not in other ALDH1 members. Moreover, we got survival data from 160 AML patients in TCGA database. We found that high ALDH1A1 expression correlated to poor Overall Survival (OS), mostly in Fms-like Tyrosine Kinase-3 (FLT3) mutated group. HighALDH1A2 expression significantly correlated to poor OS in FLT3 wild type population but not in FLT3 mutated group. High ALDH1A3 expression significantly correlated to poor OS in FLT3 mutated group but not in FLT3 wild type group. There was no relationship between the OS of AML with the level of ALDH1B1, ALDH1L1 and ALDH1L2. Conclusion: The prognostic impacts were different in each ALDH1 family members, which needs further investigation. -

Correspondence §Corresponding author: [email protected] (S.-Y.K.) §§Co-corresponding author: [email protected] (S.-S.H.) *These authors contributed equally to this work 1 Abstract Rationale: The activity of aldehyde dehydrogenase 7A1 (ALDH7A1), an enzyme that catalyzes the lipid peroxidation of fatty aldehydes was found to be upregulated in pancreatic ductal adenocarcinoma (PDAC). ALDH7A1 knockdown significantly reduced tumor formation in PDAC. We raised a question how ALDH7A1 contributes to cancer progression. Methods: To answer the question, the role of ALDH7A1 in energy metabolism was investigated by knocking down and knockdown gene in mouse model, because the role of ALDH7A1 has been reported as a catabolic enzyme catalyzing fatty aldehyde from lipid peroxidation to fatty acid. Oxygen consumption rate (OCR), ATP production, mitochondrial membrane potential, proliferation assay and immunoblotting were performed. In in vivo study, two human PDAC cell lines were used for pre-clinical xenograft model as well as spontaneous PDAC model of KPC mice was also employed for anti-cancer therapeutic effect. -

Non-P450 aldehyde oxidizing enzymes: the aldehyde dehydrogenase superfamily Satori A Marchitti, Chad Brocker*, Dimitrios Stagos*, and Vasilis Vasiliou† University of Colorado Health Sciences Center, Molecular Toxicology & Environmental Health Sciences Program, Department of Pharmaceutical Sciences, Denver, Colorado 80262, USA Abstract Background—Aldehydes are highly reactive molecules. While several non-P450 enzyme systems participate in their metabolism, one of the most important is the aldehyde dehydrogenase (ALDH) superfamily, composed of NAD(P)+-dependent enzymes that catalyze aldehyde oxidation. Objective—This article presents a review of what is currently known about each member of the human ALDH superfamily including the pathophysiological significance of these enzymes. Methods—Relevant literature involving all members of the human ALDH family was extensively reviewed, with the primary focus on recent and novel findings. Conclusion—To date, 19 ALDH genes have been identified in the human genome and mutations in these genes and subsequent inborn errors in aldehyde metabolism are the molecular basis of several diseases, including Sjögren-Larsson syndrome, type II hyperprolinemia, γ-hydroxybutyric aciduria and pyridoxine-dependent seizures. ALDH enzymes also play important roles in embryogenesis and development, neurotransmission, oxidative stress and cancer. Finally, ALDH enzymes display multiple catalytic and non-catalytic functions including ester hydrolysis, antioxidant properties, xenobiotic bioactivation and UV light absorption.

TPI1 Gene Triosephosphate Isomerase 1
TPI1 gene triosephosphate isomerase 1 Normal Function The TPI1 gene provides instructions for making an enzyme called triosephosphate isomerase 1. This enzyme is involved in a critical energy-producing process known as glycolysis. During glycolysis, the simple sugar glucose is broken down to produce energy for cells. The triosephosphate isomerase 1 enzyme carries out a specific reaction during glycolysis: the conversion of a molecule called dihydroxyacetone phosphate (DHAP) to glyceraldehyde 3-phosphate. This conversion can go both ways, meaning that the triosephosphate isomerase 1 enzyme can also convert glyceraldehyde 3-phosphate back into DHAP. Additional steps convert glyceraldehyde 3-phosphate into other molecules that ultimately produce energy in the form of a molecule called ATP. For the triosephosphate isomerase 1 enzyme to be turned on (active), it has to attach ( bind) to another triosephosphate isomerase 1 enzyme, forming a two-enzyme complex called a dimer. Health Conditions Related to Genetic Changes Triosephosphate isomerase deficiency At least 12 mutations in the TPI1 gene have been found to cause triosephosphate isomerase deficiency. This condition is characterized by a shortage of red blood cells ( anemia), movement problems, increased susceptibility to infection, and muscle weakness that can affect breathing and heart function. TPI1 gene mutations can lead to the production of an enzyme with decreased activity. As a result, glycolysis is impaired and cells have a decreased supply of energy. One TPI1 gene mutation accounts for approximately 80 percent of triosephosphate isomerase deficiency cases. This change replaces the protein building block (amino acid) glutamic acid with the amino acid aspartic acid at position 104 in the triosephosphate isomerase 1 enzyme (written as Glu104Asp or E104D). -

Oxidative Stress Activates SIRT2 to Deacetylate and Stimulate Phosphoglycerate Mutase
Published OnlineFirst May 1, 2014; DOI: 10.1158/0008-5472.CAN-13-3615 Cancer Tumor and Stem Cell Biology Research Oxidative Stress Activates SIRT2 to Deacetylate and Stimulate Phosphoglycerate Mutase Yanping Xu2,3, Fulong Li2,3, Lei Lv1,2, Tingting Li2,3, Xin Zhou2,3, Chu-Xia Deng4, Kun-Liang Guan1,2,5, Qun-Ying Lei1,2, and Yue Xiong1,2,6 Abstract Glycolytic enzyme phosphoglycerate mutase (PGAM) plays an important role in coordinating energy production with generation of reducing power and the biosynthesis of nucleotide precursors and amino acids. Inhibition of PGAM by small RNAi or small molecule attenuates cell proliferation and tumor growth. PGAM activity is commonly upregulated in tumor cells, but how PGAM activity is regulated in vivo remains poorly understood. Here we report that PGAM is acetylated at lysine 100 (K100), an active site residue that is invariably conserved from bacteria, to yeast, plant, and mammals. K100 acetylation is detected in fly, mouse, and human cells and in multiple tissues and decreases PGAM2 activity. The cytosolic protein deacetylase sirtuin 2 (SIRT2) deacetylates and activates PGAM2. Increased levels of reactive oxygen species stimulate PGAM2 deacetylation and activity by promoting its interaction with SIRT2. Substitution of endogenous PGAM2 with an acetylation mimetic mutant K100Q reduces cellular NADPH production and inhibits cell proliferation and tumor growth. These results reveal a mechanism of PGAM2 regulation and NADPH homeostasis in response to oxidative stress that impacts cell proliferation and tumor growth. Cancer Res; 74(13); 1–13. Ó2014 AACR. Introduction contains two PGAM genes, PGAM1 (also known as PGAM-B), Enhanced glycolysis, commonly referred to as the "Warburg which is expressed in brain and most other tissues, and PGAM2 effect" (1), is a distinctive and prominent feature of cancer cells.
