Previous works reported that a mild increase in homocysteine level is a risk factor for cardiovascular and neurodegenerative diseases in humans. Homocysteine thiolactone is a cyclic thioester, most of which is produced by an error-editing function of methionyl-tRNA synthetase, causing in vivo post-translational protein modifications by reacting with the(More)
Cancer-associated fibroblasts (CAF) engage in tumor progression by promoting the ability of cancer cells to undergo epithelial-mesenchymal transition (EMT), and also by enhancing stem cells traits and metastatic dissemination. Here we show that the reciprocal interplay between CAFs and prostate cancer cells goes beyond the engagement of EMT to include(More)
It is common knowledge that platelet-derived growth factor (PDGF) is a critical regulator of mesenchymal cell migration and proliferation. Nevertheless, these two cellular responses are mutually exclusive. To solve this apparent contradiction, we studied the behavior of NIH3T3 fibroblasts in response to increasing concentrations of PDGF. We found that there(More)
In adult tissue the quiescent state of a single cell is maintained by the steady state conditions of its own microenvironment for what concern both cell-cell as well as cell-ECM interaction and soluble factors concentration. Physiological or pathological conditions can alter this quiescent state through an imbalance of both soluble and insoluble factors(More)

Tyrosine kinase receptors (RTKs) represent a large family of transmembrane proteins,1,2 present in all metazoans, whose function is to transduce signals from the extracellular milieu to the inside of the cells. The common features of this protein family are: the extracellular domain, devoted to the binding to the specific receptor ligand, a single(More)
