Mitochondrial disorders are clinical phenotypes associated with mitochondrial dysfunction, which can be caused by mutations in mitochondrial DNA (mtDNA) or nuclear genes. In this review, we summarized the pathogenic mutations of nuclear genes associated with mitochondrial disorders. These nuclear genes encode, components of mitochondrial translational machinery and structural subunits and assem...

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder diagnosed by anovulation hyperandrogenism.Hyperandrogenism increases apoptosis, which will eventually disturb follicular growth in PCOS patients.Since mitochondria regulate apoptosis, they might be affected by high incidence of follicular atresia. This may causeinfertility. Since vitamin D3 has been shown to...

We analyzed 12 combined mitochondrial and nuclear gene datasets in seven orders of insects using both equal weights parsimony (to evaluate phylogenetic utility) and Bayesian methods (to investigate substitution patterns). For the Bayesian analyses we used relatively complex models (e.g., general time reversible models with rate variation) that allowed us to quantitatively compare relative rates...

Background: Nicotine alters the expression of various genes in the heart. PINK-1(PTEN-induced kinase1) is the major regulator of cellular mitophagy. Moreover, Parkin is a protein that plays a key role in the process of ubiquitination. Also, PGC-1ὰ (peroxisome proliferator-activated receptor gamma coactivator 1-alpha) is the main regulator of mitochondrial biogenesis. On the other hand, exercise...

alzheimer’s disease (ad) is the most common form of dementia in the elderly in which interplay between genes and the environment is supposed to be involved. mitochondrial dna (mtdna) has the only non-coding regions at the displacement loop (d-loop) region that contains two hypervariable segments (hvs-i and hvs-ii) with high polymorphism. mtdna has already been fully sequenced and many subsequen...

Mitochondrial aminoacyl-tRNA synthetases—encoded by ARS2 genes—are evolutionarily conserved enzymes that catalyse the attachment of amino acids to their cognate tRNAs, ensuring accuracy mitochondrial translation process. gene mutations are associated with a wide range clinical presentations affecting CNS. Two senior neuroradiologists analysed brain MRI 25 patients (age range: 3 d–25 yrs.; 11 ma...

BACKGROUND The genetic risk factors of schizophrenia (SCZ), a severe psychiatric disorder, are not yet fully understood. Multiple lines of evidence suggest that mitochondrial dysfunction may play a role in SCZ, but comprehensive association studies are lacking. We hypothesized that variants in nuclear-encoded mitochondrial genes influence susceptibility to SCZ. METHODS We conducted gene-based...

aim: this study is aimed to elicit the possible correlation between breast and colon cancer from molecular prospectiveby analyzing and comparing pathway-based biomarkers.background: breast and colon cancer are known to be frequent causes of morbidity and mortality in men and womenaround the world. there is some evidence that while the incident of breast cancer in young women is high, it is repo...
