D ata from twin, family, and adoption studies provide strong evidence that genetic factors play a major aetiological role in schizophrenia. By a series of linkage studies, chromosome 8p has been implicated as a region harbouring a schizophrenia susceptibility gene. Recently, Stefansson and colleagues reported that neuregulin 1 (NRG1), located in 8p21-12, may be involved in the aetiology of schi...
ARIA, or acetylcholine receptor-inducing activity, is a polypeptide that stimulates the synthesis of acetylcholine receptors in skeletal muscle. Here we demonstrate that the ability of ARIA to induce phosphorylation of its receptor in muscle is blocked by highly charged glycosaminoglycans. ARIA constructs lacking the NH2-terminal portion, containing an immunoglobulin-like domain, are fully acti...
Background: Dysfunction of Schwann cells by diabetes has far-reaching consequences for the structure and function of peripheral nerves. The aim of the present study was to evaluate the effect of aerobic exercise on the Nrg1 / ErbB2 signaling pathway in male rats with diabetic neuropathic pain. Methods: Twenty-four 8-week-old male Wistar rats (weight range 204 ± 11.3 g) were randomly divided in...
The phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) pathway is frequently hyper-activated upon vemurafenib treatment of melanoma. We have here investigated the relationship between SRY-box 10 (SOX10), forkhead box 3 (FOXD3) and microphthalmia-associated transcription factor (MITF) in the regulation of the receptor tyrosine-protein kinase ERBB3, and its cognate ligand neuregulin 1-beta (NR...
Head and neck squamous cell carcinoma (HNSCC) accounts for 3-5% of all tumor types and remains an unmet medical need with only two targeted therapies approved to date. ErbB3 (HER3), the kinase-impaired member of the EGFR/ErbB family, has been implicated as a disease driver in a number of solid tumors, including a subset of HNSCC. Here we show that the molecular components required for ErbB3 act...
All four members of the human epidermal growth factor (EGF) receptor (HER) family are implicated in human cancers. Although efficacious in a subset of patients, resistance to single-targeted anti-HER therapy [i.e., cetuximab (Erbitux) and trastuzumab (Herceptin)] is often associated with coexpression of other HER family members. This may be overcome by a HER ligand binding molecule that sequest...
PURPOSE To identify druggable oncogenic fusions in invasive mucinous adenocarcinoma (IMA) of the lung, a malignant type of lung adenocarcinoma in which KRAS mutations frequently occur. EXPERIMENTAL DESIGN From an IMA cohort of 90 cases, consisting of 56 cases (62%) with KRAS mutations and 34 cases without (38%), we conducted whole-transcriptome sequencing of 32 IMAs, including 27 cases withou...
AXOGIAL COMMUNICATION MEDIATED BY SOLUBLE NEUREGULIN-1 AND BDNFbyZHENZHONG MAAugust 2011Advisor: Jeffrey A. Loeb, M.D., Ph.D.Major: Molecular Biology & GeneticsDegree: Doctor of PhilosophyDuring peripheral nervous system development, successful communication betweenaxons and glial cells including Schwann cells in peripheral nervous system andoligodendrocytes ...
Neuregulin1-ErbB signaling is important for various functions during Schwann cell development and myelination. Activation of the ErbB receptors also triggers myelin breakdown in mature myelinating Schwann cells. The mechanism by which the activated ErbB receptor complex elicits multiple biological functions in Schwann cells is unclear. In Charcot-Marie-Tooth (CMT) disease-the most common demyel...
Regulated intramembrane proteolysis by gamma-secretase cleaves proteins in their transmembrane domain and is involved in important signaling pathways. At least four different gamma-secretase complexes have been identified, but little is known about their biological role and specificity. Previous work has demonstrated the involvement of the Aph1A-gamma-secretase complex in Notch signaling, but n...
