The transcriptional co-activator PGC-1 and the NAD -dependent deacetylase SIRT1 are considered important inducers of mitochondrial biogenesis because in the nucleus they regulate transcription of nucleus-encodedmitochondrial genes. We demonstrate that PGC-1 and SIRT1 are also present inside mitochondria and are in close proximity tomtDNA. They interact with mitochondrial transcription factor A ...
amorpha-4, 11-diene synthase (ads) gene is the first and important gene in artemisinin biosynthesis pathway that why for many researchers, the study of how to regulate of this gene is important. transcription factors can change the expression rate of several genes simultaneously. in this study, six wild accessions of artemisia annua, collected from golestan province, were used. many known trans...
BACKGROUND Mitochondrial DNA (mtDNA) copy number is decreased not only in mtDNA-mutation diseases but also in a wide variety of acquired degenerative and ischemic diseases. Mitochondrial transcription factor A (TFAM) is essential for mtDNA transcription and replication. Myocardial mtDNA copy number and TFAM expression both decreased in cardiac failure. However, the functional significance of TF...
Mitochondrial DNA (mtDNA) is maintained within nucleoprotein complexes known as nucleoids. These structures are highly condensed by the DNA packaging protein, mitochondrial Transcription Factor A (TFAM). Nucleoids also include RNA, RNA:DNA hybrids, and are associated with proteins involved with RNA processing and mitochondrial ribosome biogenesis. Here we characterize the ability of TFAM to bin...
This paper reviews the current understanding of the molecular basis of the peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α)-mediated pathway and discusses the role of PGC-1α in skeletal muscle atrophy caused by immobilization. PGC-1α is the master transcription regulator that stimulates mitochondrial biogenesis, by upregulating nuclear respiratory factors (NRF-1, 2) and mito...
Oxidative stress-induced mitochondrial dysfunction and mitochondrial DNA (mtDNA) damage in peripheral neurons is considered to be important in the development of diabetic neuropathy. Mitochondrial transcription factor A (TFAM) wraps mtDNA and promotes mtDNA replication and transcription. We studied whether overexpression of TFAM reverses experimental peripheral diabetic neuropathy using TFAM tr...
In colorectal cancer, no study has been carried out discovering the relationship among p53, mitochondrial transcription factor A (TFAM) expression and change of mitochondrial DNA (mtDNA) copy number. In our study, co-expression of p53 and TFAM was observed in colon adenocarcinoma tissues, paracancerous tissues and 9 colorectal cancer cell lines. Then, a significant linear correlation was establ...
Using a combination of bioinformatic and molecular biology approaches a Drosophila melanogaster protein, DmTTF, has been identified, which exhibits sequence and structural similarity with two mitochondrial transcription termination factors, mTERF (human) and mtDBP (sea urchin). Import/processing assays indicate that DmTTF is synthesised as a precursor of 410 amino acids and is imported into mit...
BACKGROUND Mitochondrial changes have been described in muscle tissue in acquired hypothyroidism. Among the molecular mechanisms by which thyroid hormones regulate expression of nuclear genes encoding for regulatory proteins of mitochondrial respiratory function, the mitochondrial transcription factor A (h-mtTFA) has been proposed to be a target of thyroid hormone action. The aim of this study ...
