MicroRNAs (miRs) are small noncoding RNAs that regulate gene expression primarily through translational repression. In erythropoietic (E) culture of cord blood CD34+ progenitor cells, the level of miR 221 and 222 is gradually and sharply down-modulated. Hypothetically, this decline could promote erythropoiesis by unblocking expression of key functional proteins. Indeed, (i) bioinformatic analys...
BACKGROUND Majority of gastrointestinal stromal tumours (GISTs) are characterised by KIT-immunopositivity and the presence of KIT/platelet-derived growth factor receptor alpha (PDGFRA) activating mutations. PATIENTS AND METHODS Spectrum and frequency of KIT and PDGFRA mutations were investigated in 427 GISTs. Univariate and multivariate analysis of relapse-free survival (RFS) was conducted in...
A rapid, cheap and effective method for diagnosing tuberculosis (TB) is essential for TB control. We evaluated the performance of an immunochromatographic assay (ICA) kit (SD Bioline TB Ag MPT64 rapid test) designed for detecting Mycobacterium tuberculosis complex (MTC) in liquid and solid cultures to determine its ability to detect and differentiate MTC directly in sputum samples. We attempted...
Activating mutations of the activation loop of KIT are associated with certain human neoplasms, including the majority of patients with systemic mast cell disorders, as well as cases of seminoma, acute myelogenous leukemia (AML), and gastrointestinal stromal tumors (GISTs). The small-molecule tyrosine kinase inhibitor imatinib mesylate is a potent inhibitor of wild-type (WT) KIT and certain mut...
BACKGROUND The survival and growth of melanocytes are controlled by the binding of stem cell factor to its cell surface receptor c-kit+ (CD117). We have observed that c-kit+ melanocytes existed in some lesions of vitiligo, while Melan A+ cells were absent. OBJECTIVE To verify possible relation between c-kit+ expression and treatment response in non-segmental vitiligo lesions. METHODS Skin b...
