TAILIEUCHUNG - Báo cáo khoa học: Mutation of epidermal growth factor receptor is associated with MIG6 expression

Controlled activation of epidermal growth factor receptor (EGFR) is sys-tematically guaranteed at the molecular level; however, aberrant activation of EGFR is frequently found in cancer. Transcription induced by EGFR activation often involves the coordinated expression of genes that positively and negatively regulate the original signaling pathway; therefore, altera-tions in EGFR kinase activity may reflect changes in gene expression asso-ciated with the pathway. | ỊFEBS Journal Mutation of epidermal growth factor receptor is associated with MIG6 expression Takeshi Nagashima1 Ryoko Ushikoshi-Nakayama1 Atsushi Suenaga2 Kaori Ide1 Noriko Yumoto1 VAchimi M o f I I A3 iố o 1 f I I Tq Izil Ji o Q Ji 11 I lz 1 QqqI i Tuĩiĩ2 I IĨk icJiĨ TariQl a3 OJ tiJ t Enn 1 Tcqi4 Yoshimi Naruo Kaoru Takahashi Yuko Saeki Makoto Taiji Hiroshi Tanaka Shih-Feng Tsai and Mariko Hatakeyama1 1 Cellular Systems Modeling Team ComputationalSystems Biology Research Group Advanced ComputationalSciences Department RIKEN Advanced Science Institute Yokohama Kanagawa Japan 2 High-Performance Molecular Simulation Team ComputationalSystems Biology Research Group Advanced ComputationalSciences Department RIKEN Advanced Science Institute Yokohama Kanagawa Japan 3 Schoolof BiomedicalScience Tokyo Medicaland DentalUniversity Tokyo Japan 4 Division of Molecular and Genomic Medicine NationalHealth Research Institutes Zhunan Miaoli Taiwan Keywords EGFR gene expression MIG6 mutation signal transduction Correspondence M.
