Heterogenous mismatch-repair status in colorectal cancer
BACKGROUND Immunohistochemical staining for mismatch repair proteins is efficient and widely used to identify mismatch repair defective tumors. The tumors typically show uniform and widespread loss of MMR protein staining. We identified and characterized colorectal cancers with alternative, heterogenous mismatch repair protein staining in order to delineate expression patterns and underlying me...
متن کاملIrinotecan and mismatch repair deficiency.
We read the recent publications of Ychou et al. [1, 2] on ‘adjuvant’ irinotecan-based chemotherapy in high-risk localized colorectal cancer (CRC) and after resection of liver-confined metastatic disease with great interest. In contrast to the improved outcome provided by oxaliplatin-based adjuvant treatment of early-stage disease, there is now a body of evidence showing that the addition of iri...
متن کاملDNA mismatch repair.
DNA mismatch repair (MMR) is an evolutionarily conserved process that corrects mismatches generated during DNA replication and escape proofreading. MMR proteins also participate in many other DNA transactions, such that inactivation of MMR can have wide-ranging biological consequences, which can be either beneficial or detrimental. We begin this review by briefly considering the multiple functi...
متن کاملSnapShot: DNA Mismatch Repair
Mismatch Repair in Bacteria and Eukaryotes Mismatch repair in the bacterium Escherichia coli is initiated when a homodimer of MutS binds as an asymmetric clamp to DNA containing a variety of base-base and insertion-deletion mismatches. The MutL homodimer then couples MutS recognition to the signal that distinguishes between the template and nascent DNA strands. In E. coli, the lack of adenine m...
متن کاملMismatch repair: Origin of species?
Mismatch repair reverses replication errors and inhibits recombination between diverged sequences. This has been suggested to be important in speciation, especially in prokaryotes, but theoretical analysis indicates that genetic divergence in bacterial populations is not constrained by naturally occurring recombination levels.
