Mitochondrial DNA depletion in respiratory chain-deficient Parkinson disease neurons.
Lübeck, Germany. In Ann Neurol, Dec 2015
METHODS: Multiple-label immunofluorescence was applied to postmortem sections of 10 IPD patients and 10 controls to quantify the abundance of CI-IV subunits (NDUFB8 or NDUFA13, SDHA, UQCRC2 and COXI), and mitochondrial transcription factors (TFAM and TFB2M) relative to mitochondrial mass (Porin and GRP75) in dopaminergic neurons.
Cyclophilin-D: a resident regulator of mitochondrial gene expression.
North Chicago, United States. In Faseb J, Jul 2015
We demonstrated in HEK 293T cells that transfected Cyp-D interacts with mitochondrial transcription factors B1 and B2 (TFB2M) but not with mitochondrial transcription factor A. We also demonstrated that Cyp-D interacts in vivo with TFB2M.
Echinochrome a increases mitochondrial mass and function by modulating mitochondrial biogenesis regulatory genes.
Pusan, South Korea. In Mar Drugs, 2014
Furthermore, Ech A treatment up-regulated biogenesis of regulatory transcription genes, including proliferator-activated receptor gamma co-activator (PGC)-1α, estrogen-related receptor (ERR)-α, peroxisome proliferator-activator receptor (PPAR)-γ, and nuclear respiratory factor (NRF)-1 and such mitochondrial transcription regulatory genes as mitochondrial transcriptional factor A (TFAM), mitochondrial transcription factor B2 (TFB2M), mitochondrial DNA direct polymerase (POLMRT), single strand binding protein (SSBP) and Tu translation elongation factor (TUFM).
Accessorizing the human mitochondrial transcription machinery.
New Haven, United States. In Trends Biochem Sci, 2013
Transcription of human mtDNA is directed by a single-subunit RNA polymerase, POLRMT, which requires two primary transcription factors, TFB2M (transcription factor B2, mitochondrial) and TFAM (transcription factor A, mitochondrial), to achieve basal regulation of the system.
Something old, something new, something borrowed ...
Montréal, Canada. In Cell Metab, 2009
Two mammalian mitochondrial transcription factors (TFB1M and TFB2M) share homology with universally expressed dimethyltransferases that modify conserved adenines in the small ribosomal subunit rRNA.
Mitochondrial transcription and its regulation in mammalian cells.
Stockholm, Sweden. In Trends Biochem Sci, 2007
The mitochondrial genome is transcribed by a specialized machinery that includes a monomeric RNA polymerase, the mitochondrial transcription factor A and one of the two mitochondrial transcription factor B paralogues, TFB1M or TFB2M.
