This up-regulation is due to the lack of Hey2 and cannot be explained by the structural changes in heart morphology as shown using control animals. Part of the gene regulation was further validated using in situ hybridization. Hey1 was located to the nucleus in immunofluorescence experiments. However, experiments on protein level showed also amount of Hey1 within the cytoplasm. The nuclear localization of Hey1 was unchanged during all cell cycle phases as well as when CaMKII was co-expressed or other cellular pathways were inhibited or stimulated. Hey1 does not seem to interact with the nuclear transport proteins importin-alpha and -beta, therefore it still needs to be elucidated how Hey1 is transported into the nucleus.}, subject = {Maus}, language = {en} }
