The taste of heavy metals: Gene regulation by MTF-1
Sep 1, 2012 · MTF-1 is evolutionarily conserved from insects to humans and is the main activator of metallothionein genes, which encode small cysteine-rich proteins that can scavenge toxic heavy metals and free radicals. MTF-1 has been suggested to act as an intracellular metal sensor but evidence for direct metal sensing was scarce.
Zinc-Induced Formation of a Coactivator Complex Containing the …
Evidence obtained from coimmunoprecipitation assays revealed that exposure of the cells to zinc resulted in the rapid formation of a multiprotein complex containing MTF-1, the histone acetyltransferase p300/CBP, and the transcription factor Sp1.
Regulation of Prion Gene Expression by Transcription Factors SP1 …
Jan 9, 2009 · Expression of the prion protein is a vital component for the propagation of prion diseases; thus SP1 and MTF-1 represent new targets in the development of key therapeutics toward modulating the expression of the cellular prion protein and …
Functional Heterogeneity in the Zinc Fingers of Metalloregulatory ...
Nov 24, 2000 · The Sp1 peptide backbone with the MTF-1 zinc fingers is termed SMS, whereas the MTF-1 peptide backbone with the Sp1 zinc fingers is called MSM. The chimeric DNA constructs were prepared for transcription and translation in TnT lysates and for expression in dko7 (MTF-1−/−) cells.
Regulation of prion gene expression by transcription factors SP1 …
Jan 9, 2009 · Expression of the prion protein is a vital component for the propagation of prion diseases; thus SP1 and MTF-1 represent new targets in the development of key therapeutics toward modulating the expression of the cellular prion protein and …
The hypoxia sensitive metal transcription factor MTF-1 ... - Nature
Apr 30, 2021 · Here we demonstrated that in brain ischemia induced by transient middle cerebral occlusion (tMCAO), MTF-1 is triggered by a subsequent temporary femoral artery occlusion (FAO) and represents...
The Difference in Zinc Concentrations Required for Induction …
Dec 23, 2022 · MT1 and MT2 are considered ubiquitously expressed among the MT isoforms ranging from 1 to 4. These MT1 and MT2 transcriptions are regulated by metal regulatory transcription factor 1 (MTF1) binding to the metal response element (MRE) of the promoter, which is upregulated in response to zinc.
Metal-responsive transcription factor-1 (MTF-1) is a zinc finger protein with a central role in heavy metal homeo-stasis/detoxification. MTF-1 binds to DNA sequence motifs known as metal response elements (MREs) with a core consensus TGCRCNC.
Copper induces liver lipotoxicity disease by up-regulating Nrf2 ...
Aug 1, 2023 · Cu up-regulates lipogenesis and induces lipotoxicity disease via Nrf2 activation. Cu affects Cu metabolism and regulates the expression of MTF-1 and SP1. Cu activates Nrf2 through MTF-1 and SP1/Fyn pathway. Excessive Cu intake is harmful to obesity and NAFLD.
The hypoxia sensitive metal transcription factor MTF-1 activates …
Apr 30, 2021 · The aim of this work was to investigate whether the metal responsive transcription factor 1 (MTF-1), an important hypoxia sensitive transcription factor, may (i) interact and regulate NCX1, and (ii) play a role in the neuroprotective effect mediated by RLIP through NCX1 activation.
