Van der Woude syndrome (VWS) is an autosomal dominant craniofacial disorder representing the most frequent form of syndromic cleft lip and palate. Other characteristic features are pits of the lower lip and hypodontia. The gene shows high penetrance and seems to play an important role in orofacial development determined by the tissues involved and their(More)
Knobloch syndrome (KS), characterized by high myopia, vitreoretinal degeneration with retinal detachment, macular abnormalities and occipital encephalocele, was recently confirmed as autosomal recessive. Here we report the assignment of the gene for this syndrome to 21q22.3 with the marker D21S171 through homozygosity mapping in a highly inbred Brazilian(More)
Background—Nearly universal cardiomyopathy in Duchenne muscular dystrophy (DMD) contributes to heart failure and death. Because DMD patients show myocardial fibrosis well before functional impairment, we postulated that earlier treatment using drugs with antifibrotic effect may be beneficial. Methods and Results—Three groups of 10 utrn / ;mdx, or “het”(More)
Duchenne muscular dystrophy (DMD) is an inherited disease that causes striated muscle weakness. Recently, we showed therapeutic effects of the combination of lisinopril (L), an angiotensin converting enzyme (ACE) inhibitor, and spironolactone (S), an aldosterone antagonist, in mice lacking dystrophin and haploinsufficient for utrophin (utrn(+/-);mdx, het(More)
BACKGROUND Programmed necrosis (necroptosis) plays an important role in development, tissue homeostasis, and disease pathogenesis. The molecular mechanisms that regulate necroptosis in the heart and its physiological relevance in myocardial remodeling and heart failure remain largely unknown. METHODS AND RESULTS Here, we identified an obligate function(More)
The body composition (water, fat, protein and ash) of male and female transgenic mice which had a sheep metallothionein 1a-sheep growth hormone fusion gene and their non-transgenic controls was determined at intervals from birth to 21 days of age (weaning) in 66 mice of each group, and in an additional 64 mice over the period 25 to 98 days of age. Overall(More)
Spinal Muscular Atrophy (SMA) is an autosomal recessive disorder characterized by loss of lower motor neurons. SMA is caused by deletion or mutation of the Survival Motor Neuron 1 (SMN1) gene and retention of the SMN2 gene. The loss of SMN1 results in reduced levels of the SMN protein. SMN levels appear to be particularly important in motor neurons; however(More)
Dentinogenesis imperfecta (DGI) is an autosomal dominant inherited dental disease which affects dentin production and mineralization. Genetic linkage studies have been performed on several multigeneration informative kindreds. These studies determined linkage between DGI type II and III and group-specific component (vitamin D-binding protein). This gene(More)
Knobloch syndrome (KS) is a rare disease characterized by severe ocular alterations, including vitreoretinal degeneration associated with retinal detachment and occipital scalp defect. The responsible gene, COL18A1, has been mapped to 21q22.3, and, on the basis of the analysis of one family, we have demonstrated that a mutation affecting only one of the(More)
In the field of muscular dystrophy, striated muscle function is often assessed in vitro in dystrophin-deficient mdx mice in order to test the impact of a potential treatment strategy. Although many past studies have assessed diaphragm contractile function at or near room temperature, the diaphragm performs in vivo at 37°C. To improve translation of(More)
