Molecular mechanisms of plant metal tolerance and homeostasis
Planta, 2001Transition metals such as copper are essential for many physiological processes yet can be toxic at elevated levels. Other metals (e.g. lead) are nonessential and potentially highly toxic. Plants--like all other organisms--possess homeostatic mechanisms to maintain the correct concentrations of essential metal ions in different cellular compartments ...

This chapter focuses on transition metals. All transition metal cations are toxic—those that are essential for Escherichia coli and belong to the first transition period of the periodic system of the element and also the "toxic-only" metals with higher atomic numbers.

Metal homeostasis in Alzheimer’s disease
Expert Review of Neurotherapeutics, 2006Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by neuronal dysfunction and the formation of amyloid plaques in the brain. Although the pathological processes resulting in the onset and progression of AD are not well understood, there is a growing body of evidence to support a central role for biometals in many ...

Chloroplastic and mitochondrial metal homeostasis
Trends in Plant Science, 2011Transition metal deficiency has a strong impact on the growth and survival of an organism. Indeed, transition metals, such as iron, copper, manganese and zinc, constitute essential cofactors for many key cellular functions. Both photosynthesis and respiration rely on metal cofactor-mediated electron transport chains.

Free Radical Biology and Medicine, 2014
The molecular determinants of dementia of Alzheimer's tipe (DAT) are still not completely known; however, in the past two decades, a large body of evidence has indicated that an important contributing factor is represented by the unbalanced homeostasis of two cations: calcium (Ca(2) ) and zinc (Zn(2)).

Metal ion homeostasis in Bacillus subtilis
Current Opinion in Microbiology, 2005Bacillus subtilis, a Gram-positive soil bacterium, provides a model system for the study of metal ion homeostasis. Metalloregulatory proteins serve as the arbiters of metal ion sufficiency and regulate the expression of metal homeostasis pathways. In B.
