Recently, a novel gene-deletion method was developed for the crenarchaeal model Sulfolobus islandicus, which is a suitable tool for addressing gene essentiality in depth. Using this technique, we have investigated functions of putative DNA repair genes by constructing deletion mutants and studying their phenotype. We found that this archaeon may not encode a eukarya-type of NER (nucleotide excision repair) pathway because depleting each of the eukaryal NER homologues XPD, XPB and XPF did not impair the DNA repair capacity in their mutants. However, among seven homologous recombination proteins, including RadA, Hel308/Hjm, Rad50, Mre11, HerA, NurA and Hjc, only the Hjc nuclease is dispensable for cell viability. Sulfolobus encodes redundant BER (base excision repair) enzymes such as two uracil DNA glycosylases and two putative apurinic/apyrimidinic lyases, but inactivation of one of the redundant enzymes already impaired cell growth, highlighting their important roles in archaeal DNA repair. Systematically characterizing these mutants and generating mutants lacking two or more DNA repair genes will yield further insights into the genetic mechanisms of DNA repair in this model organism.

Polymorphisms in DNA repair genes may affect the activity of the BER (base excision repair) and NER (nucleotide excision repair) systems. Using DNA isolated from blood taken from patients (n=312) and a control group (n=320) with CRC, we have analyzed the polymorphisms of selected DNA repair genes and we have demonstrated that genotypes 51Gln/His and 148Asp/Glu of APEX gene and 23Gly/Ala of XPA gene may increase the risk of colorectal cancer. At the same time analyzing the gene-gene interactions, we suggest the thesis that the main factor to be considered when analyzing the impact of polymorphisms on the risk of malignant transformation should be intergenic interactions. Moreover, we are suggesting that some polymorphisms may have impact not only on the malignant transformation but also on the stage of the tumor.
