项目摘要

Signal transduction system activated in immortalized mast cell line which is derived from cultured mast cells of knock-in mice with germline homozygous mutation at kinase domain II was different from that in cultured mast cells of knock-in mice with germline homozygous mutation. The immortalized mast cell line had an additional mutation in the c-kit gene.Activation of newly found juxtamembrane domain germline c-kit gene gain-of-function mutation in familial GISTs was effectively inhibited by imatinib and nilotinib. We also found that activation of newly found extracellular domain c-kit gene mutation in sporadic GISTs is effectively inhibited by imatinib and nilotinib, compared to that of conventional extracellular domain c-kit gene mutation.
在永生的肥大细胞系中激活的信号转导系统,该系统源自在激酶结构域II的生殖线纯合突变的敲入小鼠的培养的肥大细胞中,与具有生殖线纯合突变的敲入小鼠培养的肥大细胞中的植物性突变不同。永生化的肥大细胞系在C-Kit基因中具有额外的突变。新发现的近去膜结构域种系C-KIT基因在家族性GISTS中的功能增益突变受到伊马替尼和尼洛替尼的有效抑制。我们还发现,与常规细胞外域C-KIT基因突变相比,伊马替尼和尼洛替尼在零星GIST中的新发现的细胞外域C-KIT基因突变有效地抑制了。
