Divalent metal‐dependent regulation of hepcidin expression by MTF‐1 [PDF]
Hepcidin is a small acute phase peptide that regulates iron absorption. It is induced by inflammation and infection, but is repressed by anaemia and hypoxia. Here we further reveal that hepcidin transcription also involves interactions between functional metal response elements (MREs) in its promoter, and the MRE‐binding transcription factor‐1 ...

Fast MTF measurement of CMOS imagers at the chip level using ISO 12233 slanted-edge methodology [PDF]
MTF measurement methods for imaging devices usually require the use of an optical system to project the image of the object onto the detector. So, MTF results quality strongly depends on the accuracy of the optical adjustments (alignments, focusing ...

Molecular Mechanisms of MTF‐1 Metalloregulation
In humans and other higher eukaryotes, the metal‐responsive element‐binding transcription factor‐1 (MTF‐1) coordinates the expression of genes involved in Zn(II) homeostasis, metal ion detoxification and protection against oxidative stress.

The Transcription Factor MTF-1 Mediates Metal Regulation of the Mouse ZnT1 Gene [PDF]
Metal regulation of the mouse zinc transporter (ZnT)-1 gene was examined in cultured cells and in the developing conceptus. Zinc or cadmium treatment of cell lines rapidly (3 h) and dramatically (about 12-fold) induced ZnT1 mRNA levels. In cells incubated in medium supplemented with Chelex-treated fetal bovine serum, to remove metal ions, levels of ...

This work provides a novel approach to monitor the aflatoxin B1 (AFB1) content in maize by near-infrared (NIR) spectra-based deep learning models that integrates Markov transition field (MTF) image coding and a convolutional neural network (CNN) strategy.

Transcription Factor MTF-1 Involved in the Cellular Response to Zinc
Heavy metals, both toxic and essential, have long been an important research focus in life science. To investigate the intracellular actions of heavy metals at the molecular level, I have been exploring protein factors involved in induction of metallothionein (MT) genes by heavy metals that specifically bind to a metal responsive element (MRE) in the ...
