Research Abstract |
Keap1-Nrf2 system is known as redox homeostasis system, and also involved carcinogenesis. In this study, disruption of Keap1-Nrf2 system in skin cancers was analyzed. Seventy-two skin cancer specimens were collected and analyzed. The mutation of KEAP1 was found in only 1 specimen, and the mutation of NRF2 and LOH in KEAP1 locus were not found. Aberrant methylation of KEAP1 was found in 4 of 72 (6%) specimens; however the methylations were weak to shutoff the expression. In conclusion, disruption of Keap1-Nrf2 system in skin cancers is rare event.
