Detection of an Involvement of the Human Mismatch Repair Genes hMLH1 and hMSH2 in Nucleotide Excision Repair Is Dependent on UVC Fluence to Cells

There is conflicting evidence for the role of the mismatch repair (MMR) genes hMLH1 and hMSH2 in the transcription-coupled repair (TCR) pathway of nucleotide excision repair. In the present work, we have examined the role of these MMR genes in nucleotide excision repair using two reporter gene assays. AdHCMVlacZ is a replication-deficient recombinant adenovirus that expresses the beta-galactosidase reporter gene under the control of the human …
