PURPOSE Resistance is commonly acquired in patients with metastatic gastrointestinal stromal tumor who are treated with imatinib mesylate, often due to the development of secondary mutations in the KIT kinase domain. We sought to investigate the efficacy of second-line tyrosine kinase inhibitors, such as sorafenib, dasatinib, and nilotinib, against the commonly observed imatinib-resistant KIT m...
The reason that a certain subgroup of acute myeloid leukemia (AML) patients with t(8;21) translocation (generating the AML1/ETO fusion gene) displays a poor survival remains elusive. The proto-oncogene c-kit is expressed in approximately 80% of AML cases. The kinase domain mutation of the c-kit gene, one of the most common gain-of-function mutations associated with t(8;21) AML, predicts higher ...
Acute myeloid leukemia (AML) is caused by the cooperation between class I, mostly mutated receptor tyrosine kinases (RTK), and class II oncoproteins, chimeric transcription factors derived from chromosomal translocations. The blasts of 80-90% of AML-patients are positive for the RTK c-Kit. In about 50% of the 'core binding factor' (CBF)-AMLs, c-Kit harbors additional gain-of-function mutations,...
In the mouse, the Kit receptor and its ligand, the stem cell factor (SCF), are encoded at the W/Kit and Steel loci, respectively. The Kit/SCF transduction pathway is involved in promoting cellular migration, proliferation and/or survival of melanoblasts, hematopoietic progenitors and primordial germ cells. Furthermore, a functional Kit/SCF pathway is required for the development of interstitial...
PURPOSE KIT aberrations were described in acral and mucosal melanomas in largely Caucasian populations. Asian populations are more prone to develop acral and mucosal than cutaneous melanomas, and may harbor a high frequency of KIT aberrations. EXPERIMENTAL DESIGN Melanoma subtypes (n = 502) were analyzed histologically to determine melanoma subtype. Tissue samples were analyzed for mutations ...
To evaluate the Equine Infectious Anemia (EIA) agar gel immunodiffusion (AGID) protocols, two different kits commercially available in Brazil were used: an imported kit (kit A) and a domestically produced kit (kit B). Kit A was submitted to the protocols recommended by the World Organization for Animal Health (OIE) and the protocol recommended by the Ministério da Agricultura Pecuária e Abastec...
