Iron-sulfur (Fe/S) cluster-containing proteins catalyse a number of electron transfer and metabolic reactions. Little is known about the biogenesis of Fe/S clusters in the eukaryotic cell. Here, we demonstrate that mitochondria perform an essential role in the synthesis of both intra- and extra-mitochondrial Fe/S proteins. Nfs1p represents the yeast orthologue of the bacterial cysteine desulfur...
Fibronectin is a matrix glycoprotein which has not only been found to be over-expressed in several cancers, but has been shown to participate in several steps of tumorigenesis. The purpose of this review is to illustrate how aberrant fibronectin expression influences tumor growth, invasion, metastasis and therapy resistance. In particular, this review will focus on the interactions between cell...
Multiphoton laser microscopy is a new, non-invasive technique providing access to the skin at a cellular and subcellular level, which is based both on autofluorescence and fluorescence lifetime imaging. Whereas the former considers fluorescence intensity emitted by epidermal and dermal fluorophores and by the extra-cellular matrix, fluorescence lifetime imaging (FLIM), is generated by the fluor...
Stress has been shown to be associated with altered homeostasis that may lead to oxidant-antioxidant imbalance. Non-enzymatic antioxidants are important regulators of reactive oxygen species produced in extra-cellular milieu and represent the first line of defense against them. Extra-cellular non-enzymatic antioxidants may be disturbed by the production of superoxide and nitric oxide and this h...
