Strain description

Eisuke mice are transgenic mice expressing cytoplasm-localized förster (or fluorescence) resonance energy transfer (FRET) biosensor EKAREV monitoring ERK kinase activity under the control of CAG promoter in whole body. Extracellular signal-regulated kinase (ERK) is belong to MAPK family and related to cellular growth and differentiation, especially plays an important role in oncogene signal transduction cascade. It's possible to measure ERK kinase activity spatially and temporally in fetal or adult various tissues by live imaging observation of this strain in the two-photon microscopy. This strain expects not only to analyze the signal transduction cascade in live animals, but also apply drug development such as the pharmacodynamic analysis targeting signal molecules, because these mice are showed rich expression in primary cultured cells derived from various tissues. In the case of using epithelial tissues when you detect the difference of ERK activity in cell lines, nucleus-localized FRET biosensor is easier to use. However, it's necessary to use cytoplasm-localized FRET biosensor if you want to observe cell forms. FRET biosensor generally can't use for fixed samples.
