[Preparation of the gene targeted knockout mice for human premature aging diseases, Werner syndrome, and Rothmund-Thomson syndrome caused by the mutation of DNA helicases].

Abstract excerpt

The list of human RecQ helicase comprises RecQ1, BLM (Bloom syndrome), WRN (Werner syndrome), RTS (Rothmund-Thomson syndrome), and RecQ5. Of these, the defective BLM, WRN, and RTS helicases are responsible for distinct but overlapping clinical features suggesting premature aging and an enhanced risk of cancer, which apparently stems from chromosomal instability in the cells of tissues and organs where expression...
