Neuroligins are postsynaptic membrane cell-adhesion molecules which bind to beta-neurexins, a family of proteins that act as neuronal cell surface receptors. To explore the possibility that structural variants in the beta-neurexin genes predispose to autism, the coding regions and associated splice junctions of three beta-neurexin genes were scanned with(More)
MicroRNAs (miRNAs) are 21-25-nucleotide-long, noncoding RNAs that are involved in translational regulation. Most miRNAs derive from a two-step sequential processing: the generation of pre-miRNA from pri-miRNA by the Drosha/DGCR8 complex in the nucleus, and the generation of mature miRNAs from pre-miRNAs by the Dicer/TRBP complex in the cytoplasm.

Neurexins are presynaptic membrane cell-adhesion molecules which bind to neuroligins, a family of proteins that are associated with autism. To explore the possibility that structural variants in the neurexin alpha genes predispose to autism, the coding regions and associated splice junctions of the neurexin 1alpha gene were sequenced in 116 Caucasian(More)
Dilated cardiomyopathy (DCM) is the major indication for heart transplantation. Approximately 30% of all DCM is thought to be inherited, while 70% is sporadic. Mutations in the dystrophin gene have been associated with the uncommon X-linked form of DCM. We hypothesized that missense mutations and other less severe mutations of the dystrophin gene might(More)
Neuropathic pain is a debilitating clinical condition with few efficacious treatments, warranting development of novel therapeutics. We hypothesized that dysregulated translation regulation pathways may underlie neuropathic pain. Peripheral nerve injury induced reorganization of translation machinery in the peripheral nervous system of rats and mice,(More)
Despite the emergence of translational control pathways as mediators of nociceptive sensitization, effector molecules and mechanisms responsible for modulating activity in these pathways in pain conditions are largely unknown. We demonstrate that two major algogens, the cytokine interleukin 6 (IL-6) and the neurotrophin nerve growth factor (NGF), which are(More)
Acute leukemia characterized by chromosomal rearrangements requires additional molecular disruptions to develop into full-blown malignancy, yet the cooperative mechanisms remain elusive. Using whole-genome sequencing of a pair of monozygotic twins discordant for MLL (also called KMT2A) gene-rearranged leukemia, we identified a transforming MLL-NRIP3 fusion(More)
Actin cables in pollen tubes serve as molecular tracks for cytoplasmic streaming and organelle movement and are formed by actin bundling factors like villins and fimbrins. However, the precise mechanisms by which actin cables are generated and maintained remain largely unknown. Fimbrins comprise a family of five members in Arabidopsis thaliana. Here, we(More)
An analysis of mutations was performed in 141 Duchenne muscular dystrophy (DMD) patients previously found to be negative for large deletions by standard multiplex PCR assays. Comprehensive mutation scanning of all coding exons, adjacent intronic splice regions, and promoter sequences was performed by DOVAM-S, a robotically enhanced, high throughput method(More)
Frameshift and missense mutations in the X-linked neuroligin 4 (NLGN4, MIM# 300427) and neuroligin 3 (NLGN3, MIM# 300336) genes have been identified in patients with autism, Asperger syndrome and mental retardation. We hypothesize that sequence variants in NLGN4Y are associated with autism or mental retardation. The coding sequences and splice junctions of(More)
