Essential hypertension (EH) is a frequent, chronic, age-related disorder, which remains a major modifiable risk factor for cardiovascular disease despite important advances in our understanding of its pathophysiology. Previous studies have noted a consistent maternal effect on blood pressure (BP). Consequently, mutations in mitochondrial DNA (mtDNA) have become an additional target of investiga...

conclusions these data will be beneficial for designing more advanced antibodies for the recognition of the hbsag in diagnostics. in addition, the results of this study may assist in the design or development of more effective hepatitis b vaccines. results the g145r mutation causes a considerable reduction in the immunogenic activity of the hbsag through a conformational change in the hbsag ant...

Mitochondrial DNA has been proposed to be involved in carcinogenesis because of high susceptibility to mutations and limited repair mechanisms in comparison to nuclear DNA. In this paper, we review mitochondrial genome instability, relation of mitochondrial DNA mutations with apoptosis and mitochondrial genomic aberrations reported in solid tumors of the thyroid, colorectal, breast, and gastric

Tubulointerstitial kidney disease is an important cause of progressive renal failure whose aetiology is incompletely understood. We analysed a large pedigree with maternally inherited tubulointerstitial kidney disease and identified a homoplasmic substitution in the control region of the mitochondrial genome (m.547A>T). While mutations in mtDNA coding sequence are a well recognised cause of dis...

OBJECTIVES As mitochondrial oxidative stress is probably entailed in ATP production, a candidate modifier factor for the long QT syndrome (LQTS) could be mitochondrial DNA (mtDNA). It has been notified that ion channels' activities in cardiomyocytes are sensitive to the ATP level. MATERIALS AND METHODS The sample of the research was an Iranian family with LQTS for mutations by PCR-SSCP and DN...

SDR5C1 is an amino and fatty acid dehydrogenase/reductase, moonlighting as a component of human mitochondrial RNase P, which is the enzyme removing 5'-extensions of tRNAs, an early and crucial step in tRNA maturation. Moreover, a subcomplex of mitochondrial RNase P catalyzes the N(1)-methylation of purines at position 9, a modification found in most mitochondrial tRNAs and thought to stabilize ...

DNA polymerase gamma (pol gamma) is responsible for replication and repair of mitochondrial DNA (mtDNA). Over 150 mutations in POLG (which encodes pol gamma) have been discovered in patients with mitochondrial disorders including Alpers, progressive external ophthalmoplegia and ataxia-neuropathy syndrome. However, the severity and dominance of many POLG disease-associated mutations are unclear,...

Variants in mitochondrial DNA (mtDNA) and nuclear genes encoding mitochondrial proteins in bipolar disorder, depression, or other psychiatric disorders have been studied for decades, since mitochondrial dysfunction was first suggested in the brains of patients with these diseases. Candidate gene association studies initially resulted in findings compatible with the mitochondrial dysfunction hyp...

Mutations in the mitochondrial genome can impair normal metabolic function in the central nervous system (CNS) where cellular energy demand is high. Primary mitochondrial DNA (mtDNA) mutations have been linked to several mitochondrial disorders that have comorbid psychiatric, neurologic, and cognitive sequelae. Here, we present a series of cases with primary mtDNA mutations who were genotyped a...
