Background: Mitochondrial diseases are a group of disorders caused by dysfunctional organelles that generate energy for our body. Mitochondria small double-membrane organelles found in of the most common groups of genetic diseases with a minimum every cell of the human body except red blood cells. Mitochondrial diseases are sometimes caused by mutations in the mitochondrial DNA prevalence of greater than 1 in 5000 in adults. Mitochondrial diseases that affect mitochondrial function. Other mitochondrial diseases are can be present at birth but can be manifested also at any age [2]. -
High-Throughput, Pooled Sequencing Identifies Mutations in NUBPL And
ARTICLES High-throughput, pooled sequencing identifies mutations in NUBPL and FOXRED1 in human complex I deficiency Sarah E Calvo1–3,10, Elena J Tucker4,5,10, Alison G Compton4,10, Denise M Kirby4, Gabriel Crawford3, Noel P Burtt3, Manuel Rivas1,3, Candace Guiducci3, Damien L Bruno4, Olga A Goldberger1,2, Michelle C Redman3, Esko Wiltshire6,7, Callum J Wilson8, David Altshuler1,3,9, Stacey B Gabriel3, Mark J Daly1,3, David R Thorburn4,5 & Vamsi K Mootha1–3 Discovering the molecular basis of mitochondrial respiratory chain disease is challenging given the large number of both mitochondrial and nuclear genes that are involved. We report a strategy of focused candidate gene prediction, high-throughput sequencing and experimental validation to uncover the molecular basis of mitochondrial complex I disorders. We created seven pools of DNA from a cohort of 103 cases and 42 healthy controls and then performed deep sequencing of 103 candidate genes to identify 151 rare variants that were predicted to affect protein function. We established genetic diagnoses in 13 of 60 previously unsolved cases using confirmatory experiments, including cDNA complementation to show that mutations in NUBPL and FOXRED1 can cause complex I deficiency. Our study illustrates how large-scale sequencing, coupled with functional prediction and experimental validation, can be used to identify causal mutations in individual cases. Complex I of the mitochondrial respiratory chain is a large ~1-MDa assembly factors are probably required, as suggested by the 20 factors macromolecular machine composed of 45 protein subunits encoded necessary for assembly of the smaller complex IV9 and by cohort by both the nuclear and mitochondrial (mtDNA) genomes. -
Health Effects Support Document for Perfluorooctanoic Acid (PFOA)
United States Office of Water EPA 822-R-16-003 Environmental Protection Mail Code 4304T May 2016 Agency Health Effects Support Document for Perfluorooctanoic Acid (PFOA) Perfluorooctanoic Acid – May 2016 i Health Effects Support Document for Perfluorooctanoic Acid (PFOA) U.S. Environmental Protection Agency Office of Water (4304T) Health and Ecological Criteria Division Washington, DC 20460 EPA Document Number: 822-R-16-003 May 2016 Perfluorooctanoic Acid – May 2016 ii BACKGROUND The Safe Drinking Water Act (SDWA), as amended in 1996, requires the Administrator of the U.S. Environmental Protection Agency (EPA) to periodically publish a list of unregulated chemical contaminants known or anticipated to occur in public water systems and that may require regulation under SDWA. The SDWA also requires the Agency to make regulatory determinations on at least five contaminants on the Contaminant Candidate List (CCL) every 5 years. For each contaminant on the CCL, before EPA makes a regulatory determination, the Agency needs to obtain sufficient data to conduct analyses on the extent to which the contaminant occurs and the risk it poses to populations via drinking water. Ultimately, this information will assist the Agency in determining the most appropriate course of action in relation to the contaminant (e.g., developing a regulation to control it in drinking water, developing guidance, or deciding not to regulate it). The PFOA health assessment was initiated by the Office of Water, Office of Science and Technology in 2009. The draft Health Effects Support Document for Perfluoroctanoic Acid (PFOA) was completed in 2013 and released for public comment in February 2014. -

Dedicated to my family, my teachers and all of my beloved ones for their love and support ii ACKNOWLEDGEMENTS My advanced academic journey began 5 years ago on the opposite side of the world. I traveled to the United States from Thailand in search of a better understanding of science so that one day I can return to my homeland and apply the knowledge and experience I have gained to improve the lives of those affected by sickness and disease yet unanswered by science. Ultimately, I hoped to make the academic transition into the scholarly community by proving myself through scientific research and understanding so that I can make a meaningful contribution to both the scientific and medical communities. The following dissertation would not have been possible without the help, support, and guidance of a lot of people both near and far. I wish to thank all who have aided me in one way or another on this long yet rewarding journey. My sincerest thanks and appreciation goes to my advisors Philip Morgan and Margaret Sedensky. -

However, direct evidence for a role of these toxins in CKD-related vascular calcification has not been reported. Methods To study early and late vascular alterations by toxin exposure, we exposed CKD rats to vehicle, IS (150 mg/kg per day), or PCS (150 mg/kg per day) for either 4 days (short-term exposure) or 7 weeks (long-term exposure). We also performed unbiased proteomic analyses of arterial samples coupled to functional bioinformatic annotation analyses to investigate molecular signaling events associated with toxin-mediated arterial calcification. Results Long-term exposure to either toxin at serum levels similar to those experienced by patients with CKD significantly increased calcification in the aorta and peripheral arteries. -
Physiologic Roles of Soluble Pyridine Nucleotide Transhydrogenase in <Emphasis Type="Italic">Escherichia Coli &L
Annals of Microbiology, 58 (2) 275-280 (2008) Physiologic roles of soluble pyridine nucleotide transhydrogenase in Escherichia coli as determined by homologous recombination Hanjun ZHAO, Peng WANG, Enqi HUANG, Yadong GE, Guoping ZHU* The Key Laboratory of Molecular Evolution and the Institute of Molecular Biology and Biotechnology, Anhui Normal University, 1 Beijing Road, Wuhu, Anhui 241000, P.R. China Received 28 January 2008 / Accepted 15 April 2008 Abstract - The soluble transhydrogenase is an energy-independent flavoprotein and important in cofactor regenerating system. In order to understand its physiologic roles, the recombinant strain with the deletion of soluble transhydroge- nase gene (ΔudhA)in Escherichia coli was constructed using homologous recombination. Then the different genetic back- grounds containing either icdNADP or icdNAD, which encodes NADP-dependent isocitrate dehydrogenase (IDH) or engineered NAD-dependent IDH, were transduced into ΔudhA, creating two strains (icdNADP/ΔudhA, icdNAD/ΔudhA). During growth on acetate, icdNADP/ΔudhA grew poorly and its growth rate was remarkably reduced by 75% as compared with the wild type. However, icdNAD/ΔudhA showed significantly better growth than icdNADP/ΔudhA. Its growth rate was about 3.7 fold of icdNADP/ΔudhA, which was equivalent to the wild type. These results indicated that UdhA is an essential NADH resource for acetate-grown E. coli and is a dominant factor for bacteria to adapt to the stress environment. Furthermore, when UdhA was absence, icdNAD/ΔudhA displayed about 1.5 fold increase in the IDH activity after switching the carbon source from glucose to acetate. And RT-PCR showed that the expression of NADH dehydrogenase II (NDH-2) in icdNAD/ΔudhA was remarkably up-regulated by about 2.8 fold as compared with icdNADP/ΔudhA. -

Defects in NDUFS8 are associated with Leigh syn- drome and encephalomyopathy. Cell-penetrating peptide derived from the HIV-1 transactivator of transcription protein (TAT) has been successfully applied as a carrier to bring fusion proteins into cells without compromising the biological function of the cargoes. In this study, we developed a TAT-mediated protein transduction system to rescue complex I deficiency caused by NDUFS8 defects. Two fusion proteins (TAT-NDUFS8 and NDUFS8-TAT) were exogenously expressed and Citation: Lin, B.-Y.; Zheng, G.-T.; purified from Escherichia coli for transduction of human cells. In addition, similar constructs were Teng, K.-W.; Chang, J.-Y.; Lee, C.-C.; generated and used in transfection studies for comparison.
