Mutations in the human actin depolymerizing factor cofilin2 result in an autosomal dominant form of nemaline myopathy. Here, we report on the targeted ablation of murine cofilin2, which leads to a severe skeletal muscle specific phenotype within the first two weeks after birth. Apart from skeletal muscle, cofilin2 is also expressed in heart and CNS, however(More)
Functional gap junction channels composed of certain connexin proteins are essential for the function of the cochlea. Homozygous deficiency in the Gjb2 (mice) or GJB2 (human) gene coding for connexin26 (Cx26) in the cochlea leads to hearing impairment in mice and humans, respectively. Here we have studied the functional equivalence of Cx26 and connexin32(More)
Gap junctions between murine hepatocytes are composed of two subunit proteins, connexin26 (Cx26) and connexin32 (Cx32). Previously, we found increased formation of chemically induced liver tumours but no increase in spontaneous development of preneoplastic hepatic foci in mice that lacked Cx32 and expressed decreased amounts of Cx26. In order to clarify(More)
Gene inactivation reporters are powerful tools to circumvent limitations of the widely used Cre/loxP system of conditional mutagenesis. With new conditional transgenic mouse lines expressing the enhanced cyan fluorescent protein (ECFP) instead of connexin43 (Cx43) after Cre-mediated recombination, we demonstrate dual reporter approaches to simultaneously(More)
