| Research Abstract |
We searched for genes expressed specifically in human interferon (HuIFN) -beta-treated Cockayne syndrome (CS) fibroblast cells, using the PCR differential display method. Eighteen expressed genes induced by HuIFN-beta were identified, the sequences of seven of which were highly homologous to previously cloned sequences. The cDNAs of six of these seven clones were similar to expression tagged sequences from unknown genes in databases and the remaining one was identical to the cDNA of the xeroderma pigmentosum (XP) -G gene. These results, together with the previous finding of increased resistance to ultraviolet (UV) cell-killing of CS cells pretreated with HuIFN-beta prior to UV irradiation, suggest that XP-G might be one of the genes possibly involved in the HuIFN-beta-induced UV-refractoriness.
