To examine functional complementation of WS phenotypes, we introduced a normal human chromosome 8 into a strain of WS fibroblasts (WS3RGB) immortalized by expressing a human telomerase reverse transcriptase subunit (hTERT) gene. Here, we demonstrate that the abnormal WS phenotypes including cellular sensitivities to 4-nitroquinoline-1-oxide (4NQO) and hydroxy urea (HU), and chromosomal radiosensitivity at G2 phase are corrected by expression of the WRN gene mediated by introducing a chromosome 8. This indicates that those multiple abnormal WS phenotypes are derived from a primary, but not secondary, defect in the WRN gene., Journal of radiation research, 50(3), pp.253-259; 2009}, pages = {253--259}, title = {Introduction of a Normal Human Chromosome 8 Corrects Abnormal Phenotypes of Werner Syndrome Cells Immortalized by Expressing an hTERT Gene}, volume = {50}, year = {2009} }
