查询词典 mutation

Helicobacter pylori infection causes the defect of mismatch repair in eucaryotes, and microsatellite instability in gastric epithelial cells, which increases the spontaneous mutation of relative genes, and finally results in the susceptibility to tumors in human bodies.

H pylori 感染导致了真核细胞错配修复(mismatch repair， MMR)系统的缺陷，在胃上皮细胞中引起微卫星不稳定(micrsatellite instable， MSI)，使相关基因自发突变率增加，最终可导致机体对肿瘤的易感。
