Web26 dec. 2006 · AID triggers somatic hypermutation by attacking a small number of C residues within the Ig V domains, deaminating them to U and thereby transforming a few C/G pairs into U/G mispairs (for review see reference 11).The presence of this uracil in DNA triggers an ancient pathway of DNA repair (12, 13), in which the uracil is excised from the … http://www.ichacha.net/hypermutation.html
Hypermutation in human cancer genomes: footprints and mechanisms.
WebAlthough somatic hypermutation is typically described as the generation of bp substitutions, insertions and deletions have been sporadically described. As with somatic point mutations, the analysis of these events can provide valuable information concerning somatic hypermutation itself. Anal-ysis of human V H 4 family genes generated from the ... Web17 apr. 2006 · Abstract. Malignant gliomas have a very poor prognosis. The current standard of care for these cancers consists of extended adjuvant treatment with the alkylating agent temozolomide after surgical resection and radiotherapy. Although a statistically significant increase in survival has been reported with this regimen, nearly all gliomas recur and … open country 4 quart kettle
