| Outline of Final Research Achievements |
The ERK pathway is a signaling pathway responsible for various cellular functions such as cell proliferation and differentiation. Recently, genetic mutations of MEK1 which is MAPKK of the ERK pathway were identified by genetic analysis of sporadic cancers and congenital Ras/MAPK syndromes. I found that the abnormal ERK activity caused by these MEK mutations leads to the expression of novel genes; a function-unknown protein (about 10 kDa) and long non-coding RNA (lncRNA). I confirmed that these molecules were expressed in various cancer cell lines with high ERK activity, and their strong expression was observed in several clinical cancer samples. In addition, cellular and molecular experiments showed that these gene expressions were important for cell functions such as cell proliferation and motility.
