BACKGROUND AND PURPOSE For decades, inhibitors of the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel have been used as tools to investigate the role and function of CFTR conductance in cystic fibrosis research. In the early 2000s, two new and potent inhibitors of CFTR, CFTRinh -172 and GlyH-101, were described and are now widely(More)
The protein profiles of bronchoalveolar lavage fluid (BALf) of patients belonging to three selected subsets of Polymyositis/Dermatomyositis (PM/DM) have been compared by using a combination of 2-DE and MALDI-TOF/MS or LC-MS/MS. Our study examined the hypothesis that there were distinct differences in protein expression profiles that were related to the(More)
DNA ligase I-deficient 46BR.1G1 cells show a delay in the maturation of replicative intermediates resulting in the accumulation of single- and double-stranded DNA breaks. As a consequence the ataxia telangiectasia mutated protein kinase (ATM) is constitutively phosphorylated at a basal level. Here, we use 46BR.1G1 cells as a model system to study the cell(More)
BACKGROUND Indoleamine 2,3-dioxygenase (IDO), an enzyme involved in the degradation of tryptophan (Try) to kynurenine (Kyn), is thought to suppress T-cell activity. Although a few experimental studies have suggested a role for IDO in graft acceptance, human data are scarce and inconclusive. We sought to establish whether, in lung transplant recipients(More)
This report intends to provide an updated overview of the most important methodological developments of MEKC in the field of qualitative/quantitative analysis of free amino acids in different matrices. A good number of articles published in the years 2009-2010 addresses the main applications of such procedures together with their advantages and/or(More)
This work presents the proteome profile of cultured human skin fibroblasts established from a patient affected by DNA ligase I (Lig I) deficiency syndrome, a rare disorder characterized by immunodeficiency, growth retardation and sun sensitivity. 2-DE (in the 3-10 and 4-7 pH ranges) was the separation technique used for the production of maps. MALDI-TOF/MS(More)
Nasu-Hakola disease (NHD) is a recessively inherited rare disorder characterized by a combination of neuropsychiatric and bone symptoms which, while being unique to this disease, do not provide a rationale for the unambiguous identification of patients. These individuals, in fact, are likely to go unrecognized either because they are considered to be(More)
To improve the knowledge on a variety of severe disorders, research has moved from the analysis of individual proteins to the investigation of all proteins expressed by a tissue/organism. This global proteomic approach could prove very useful: (i) for investigating the biochemical pathways involved in disease; (ii) for generating hypotheses; or (iii) as a(More)
