Project description:Defects of mitochondrial functions lead in humans to vast array of usually multisystemic pathologies and several hundreds of diseases resulting from various defects of mitochondria biogenesis and maintenance, defects of respiratory chain complexes (OXPHOS) or defects of individual mitochondrial proteins are known. We used Agilent Whole Human Genome Microarray for gene expression profiling of genetically heterogeneous group of 13 patients with biochemically proven ATP synthase deficiency. Gene expression data analysis allowed classification of patients into several distinct groups, provided information on subgroup and patient specific gene expression profiles, defined candidate disease causing genes and gave basic information on pathogenic mechanisms associated with ATP synthase deficiency. Keywords: ATP synthase, mitochondrial biogenesis, ROS, gene expression, microarray, human Two-condition experiment, patients vs. controls cells. Biological replicates: 9 control, 13 patients, independently grown and harvested.

Project description:Defects of mitochondrial functions lead in humans to vast array of usually multisystemic pathologies and several hundreds of diseases resulting from various defects of mitochondria biogenesis and maintenance, defects of respiratory chain complexes (OXPHOS) or defects of individual mitochondrial proteins are known. To strengthen diagnostic work-up for various mitopathies we designed focused oligonucleotide microarray which allows expression profiling of 1632 human mitochondria related genes and tested its performance in analysis of genetically heterogeneous group of 13 patients with biochemically proven ATP synthase deficiency. Gene expression data analysis allowed classification of patients into several distinct groups, provided information on subgroup and patient specific gene expression profiles, defined candidate disease causing genes and gave basic information on pathogenic mechanisms associated with ATP synthase deficiency. Two-condition experiment, patients vs. controls cells. Biological replicates: 9 control, 13 patients, independently grown and harvested. Two replicates per array.

Project description:TMEM70 (transmembrane protein 70), a 21 kDa protein localized in the inner mitochondrial membrane, facilitates the biogenesis of mammalian F1Fo ATP synthase. Mutations of Tmem70 gene represent most frequent cause of isolated deficiency of human ATP synthase resulting in a severe, often fatal neonatal mitochondrial encephalo-cardiomyopathy. Contrary to humans, targeting of Tmem70 results in embryonic lethality in both mice and rats. In the current study, we tested effects of downregulation of the Tmem70 gene on gene transcription in the SHR (spontaneously hypertensive rat) heterozygotes.We performed gene expression profiling in the liver and found differentially expressed genes involved in innate imunity (RT1-T24-4, RT1-N3, RT1-CE5, Cd36, Marco, Socs3) and regulation of oxidative phosphorylation (Cdk1, Ccna2, Slc25a3).

Project description:The goal of this analysis was to profile the gene expression signatures associated to different neuronal doses of IF1. The mitochondrial ATP synthase produces ATP by oxidative phosphorylation and integrates different signals to regulate cellular functions and fate. The ATPase inhibitory factor 1 (IF1) is a structurally-disordered protein that inhibits the ATP synthase, contributing to metabolic reprogramming and signalling through mitochondrial reactive oxygen species (mtROS). mtROS regulate kinases and transcription factors in mitohormetic responses that favour adaptation to toxic insults. IF1 is tissue-specifically expressed and in human and mouse brain is in molar excess over the ATP synthase. Herein, we have used genetic approaches to ablate or overexpress IF1 in neurons to investigate its role in brain functions. IF1 inhibits a fraction of the ATP synthase under physiological conditions and regulates respiration, mtROS production and mitochondrial structure. Transcriptomic, proteomic and metabolomic analyses indicate that IF1 regulates synaptic transmission and cognition. Ablation of IF1 impairs short-term memory whereas IF1 overexpression increases basal synaptic transmission and learning by mtROS-dependent activation of the extracellular signal-regulated kinases 1/2 (ERK 1/2). Overall, we show that IF1 dose plays a fundamental role in the regulation of neuronal function by controlling the fraction of inhibited ATP synthase that acts as source of mitohormetic mtROS, further emphasizing the ATP synthase/IF1 as promising targets to treat cognitive disorders.

Project description:Transcriptional profiling of Homo sapiens inflammatory skin diseases (whole skin biospies): Psoriasis (Pso), vs Atopic Dermatitis (AD) vs Lichen planus (Li), vs Contact Eczema (KE), vs Healthy control (KO) In recent years, different genes and proteins have been highlighted as potential biomarkers for psoriasis, one of the most common inflammatory skin diseases worldwide. However, most of these markers are not psoriasis-specific but also found in other inflammatory disorders. We performed an unsupervised cluster analysis of gene expression profiles in 150 psoriasis patients and other inflammatory skin diseases (atopic dermatitis, lichen planus, contact eczema, and healthy controls). We identified a cluster of IL-17/TNFα-associated genes specifically expressed in psoriasis, among which IL-36γ was the most outstanding marker. In subsequent immunohistological analyses IL-36γ was confirmed to be expressed in psoriasis lesions only. IL-36γ peripheral blood serum levels were found to be closely associated with disease activity, and they decreased after anti-TNFα-treatment. Furthermore, IL-36γ immunohistochemistry was found to be a helpful marker in the histological differential diagnosis between psoriasis and eczema in diagnostically challenging cases. These features highlight IL-36γ as a valuable biomarker in psoriasis patients, both for diagnostic purposes and measurement of disease activity during the clinical course. Furthermore, IL-36γ might also provide a future drug target, due to its potential amplifier role in TNFα- and IL-17 pathways in psoriatic skin inflammation.
