In order to describe diffusion of a penetrant in a polymer entanglement network, one must incorporate nonlocal effects. Most previous models have included nonlocality in time only; however, by exploiting the disparate length scales in such systems, one can model these effects by a partial integrodifferential equation which is nonlocal in space. When considering the case of diffusion near the gl...
Autism spectrum disorders (ASD) are etiologically heterogeneous, with hundreds of rare, highly penetrant mutations and genomic imbalances involved, each contributing to a very small fraction of cases. In this issue of Molecular Autism, Soorya and colleagues evaluated 32 patients with Phelan-McDermid syndrome, caused by either deletion of 22q13.33 or SHANK3 mutations, using gold-standard diagnos...
Alzheimer's disease (AD) is a genetically complex disorder. Mutations in the amyloid precursor protein and presenilin 1 (PS1) genes are fully penetrant and cause early-onset AD. Mutations in presenilin 2, a PS1 homologue, cause partially penetrant autosomal dominant AD with onset age beginning at 40 years and extending past 75 years. A fourth gene, apolipoprotein E (ApoE) is a risk-factor for l...
We show that combinatorial mouse alleles for the secreted metalloproteases Adamts5, Adamts20 (bt), and Adamts9 result in fully penetrant soft-tissue syndactyly. Interdigital webs in Adamts5(-/-);bt/bt mice had reduced apoptosis and decreased cleavage of the proteoglycan versican; however, the BMP-FGF axis, which regulates interdigital apoptosis was unaffected. BMP4 induced apoptosis, but withou...
The L1 family of cell adhesion molecules (L1CAMs) is important for neural development. Mutations in one of the human L1CAM genes, L1, can result in several neurological syndromes, the symptoms of which are variably penetrant. The physiological cause of these symptoms, collectively termed CRASH, is not clear. Caenorhabditis elegans animals genetically null for the L1CAM homologue LAD-1, exhibit ...
Microtubule (MT) stabilizing drugs hold promise as potential treatments for Alzheimer's disease (AD) and related tauopathies. However, thus far epothilone D has been the only brain-penetrant MT-stabilizer to be evaluated in tau transgenic mice and in AD patients. Furthermore, this natural product exhibits potential deficiencies as a drug candidate, including an intravenous route of administrati...
