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...
We previously reported that the K562 cell line K562YO expressed a high level of the c-kit gene. In this study, we analyzed the mechanism of this expression and investigated the effects of the serine/threonine kinases such as protein kinase C (PKC) and cyclic adenosine 3',5'-monophosphate (cAMP)-dependent kinase (PKA) on it. The half-life of the c-kit mRNA in K562YO cells was greater than 10 hou...
PURPOSE Clinicobiological characteristics of neuroblastic tumor (NT) expressing c-kit tyrosine kinase receptor and/or its ligand, stem cell factor (SCF), are debated. This study aimed at investigating the clinicobiological features of primary NTs expressing c-kit and/or SCF in order to define the clinical relevance of selective therapeutic targeting. EXPERIMENTAL DESIGN c-Kit and SCF expressi...
During development, mice with mutations of stem cell factor (SCF) or its receptor c-kit exhibit defects in melanogenesis, as well as hematopoiesis and gonadogenesis. Because melanocytes derive from neural crest cells, the role of SCF and c-kit was investigated in the neural crest-derived childhood tumor neuroblastoma. Using reverse transcription-polymerase chain reaction analysis, simultaneous ...
