## Background: Several convincing studies have shown that the hmsh2 gene plays major roles in mismatch repair by recognizing mismatched bases and preventing mutations during dna replication. loss of this function may result in the accumulation of dna replication errors or even the mutator phenotype
We examined the p53 status of 108 NSCLCs compared to the expression of MLH1 and MSH2 proteins. p53 overexpression was demonstrated by IHC in 64% of patients examined, whereas p53 mutations were detected in 43%. Twenty-two percent of mutations were located outside of the hot-spot (exons 5-8) area. p5
