Abstract
We identified that, compared with SLD fibroblasts, normal fibroblasts promoted myogenesis of primary SLD myoblasts by improving their differentiation potential in a paracrine fashion, and this effect was involved in both primary and secondary fusions. This process was also coupled with up-regulation...

Abstract
We tried to identity the signaling mechanism and develop a system to assess pro-longevity status in cells and mice. We previously identified genes up-regulated in the liver of DF and CR mice by DNA microarray analysis. Motif analysis of the upstream sequences of those genes revealed four major conse...

Abstract
Hypothalamic tuberoinfundibular dopaminergic (TIDA) neurons secrete dopamine, which inhibits pituitary prolactin (PRL) secretion. PRL has demonstrated neurotrophic effects on TIDA neuron development in PRL-, GH-, and TSH-deficient Ames (df/df) and Snell (dw/dw) dwarf mice. However, both PRL and PRL...

Abstract
We present strong histological evidence that M. dacus was indeed a dwarf (phyletic nanoid). Bone histological analysis of an ontogenetic series of Magyarosaurus limb bones indicates that even the smallest Magyarosaurus specimens exhibit a bone microstructure identical to fully mature or old individu...

Abstract
We identified one patient with a 12q14 microdeletion. The 12q14 microdeletion syndrome is characterised by dwarfism but it additionally includes mental retardation and osteopoikilosis. The deletion in our patient is smaller than those in the 12q14 microdeletion carriers but it also affects the LEMD3...

Abstract
Two different forms of dyssegmental dysplasia can be distinguished; the lethal Silverman-Handmaker type and less severe Rolland-Desbuquois type. Patients with Rolland-Desbuquois type often survive beyond neonatal period. The purpose of this paper is to report a rare case of Dyssegmental dysplasia, R...

We sought to create mice with a hypomorphic Atr mutation based on the ATR mutation in the human disease Seckel syndrome-1 (SCKL1). Homozygous SCKL1 mice were generated by targeted knock-in of the A --> G SCKL1 mutation. Western blot and RT-PCR analysis established that homozygotes have no reduction...

Abstract
Pycnodysostosis is a rare clinical entity, first described in 1962 by Maroteaux and Lamy. It is a genetic disorder, usually diagnosed at an early age. However, the diagnosis is sometimes late, made as a result of bone fracture, given the severe bone fragility resulting from increased bone density. O...

Abstract
We generated chondrocyte-specific bcl-x knock-out mice using the Cre-loxP recombination system, and we provided evidence that the hypertrophic chondrocyte layer was shortened in those mice because of an increased apoptosis of prehypertrophic and hypertrophic chondrocytes, with the mice afflicted wit...

We determined that 30-fold to greater than 100-fold more CNP(lbab) was required to activate NPR-B as compared to wild-type CNP in whole cell cGMP elevation and membrane guanylyl cyclase assays. The reduced ability of CNP(lbab) to activate NPR-B was explained, at least in part, by decreased binding s...

We hypothesize that these individuals are myxoedematous endemic (ME) cretins, part of an inland population of (mostly unaffected) Homo sapiens.
