Metal-regulatory transcription factor 1

MTF-1, Myt1
This gene encodes a transcription factor that induces expression of metallothioneins and other genes involved in metal homeostasis in response to heavy metals such as cadmium, zinc, copper, and silver. The protein is a nucleocytoplasmic shuttling protein that accumulates in the nucleus upon heavy metal exposure and binds to promoters containing a metal-responsive element (MRE).

Yun et al., Chŏnju, South Korea. In J Hazard Mater, Feb 2016
Hence to confirm the oxidative stress and genotoxic effects the mRNA expression of stress related (MTF-1, HSP70) and immune response related (TLR4, NFKB, IL1B, CEBP, TRF, TLR22) genes were analyzed in liver tissues and the results clearly concluded that the plant extract mediated synthesis of AgNPs leads to oxidative stress and immunotoxicity in adult zebrafish.
Osteoarthritis year in review 2015: biology.
Review
New
Malfait, Chicago, United States. In Osteoarthritis Cartilage, Jan 2016
Highlights include a homeostatic role for CXC chemokines in cartilage, identification of the zinc-ZIP8-MTF1 axis as an essential regulator of cartilage catabolism, and the discovery that a small aggrecan fragment can have catabolic and pro-inflammatory effects through Toll-like receptor 2. Synovitis can promote joint damage, partly through alarmins such as S100A8.

Review
Terkeltaub et al., San Diego, United States. In Nat Rev Rheumatol, 2015
Integral to this reprogramming are 'switching' pathways in transcriptional networks, other than the well-characterized effects of NFκB and mitogen-activated protein kinase signalling; HIF-2α transcriptional signalling and ZIP8-mediated Zn(2+) uptake, with downstream MTF1 transcriptional signalling, have been implicated but further validation is required.
