abstract: colorectal cancer (crc) is the third most common cancer in men and the second most common cancer in women worldwide. both genetic and epigenetic alterations are common in crc and are the driving force of tumorigenesis. chromosomal instability, microsatellite instability and cpg island methylator phenotype pathways are responsible for genetic instability in colorectal cancer. chromosom...

abstract   background: the polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. from the evidence that the dnamismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability a feature of malig...

in the popular tale " Ozma of Oz, " Lyman Frank Baum describes the princess Langwidere, who is capable of interchanging her currently worn head with another one, using a collection of heads stored in a cabinet. Remarkably, she changes her character as well when putting a new head on her neck. in the December 15, 2012 issue of Cell Cycle, Kurt Engeland and colleagues report a similar phenomenon ...
