Journal:Assay Drug Dev Technol
PubMed ID:20085456
'The mTORC1 pathway is a central regulator of cell growth, and defective mTORC1 regulation plays a causative role in a variety of human diseases, including cancer, tumor syndromes such as the tuberous sclerosis complex (TSC) and lymphangioleiomyomatosis (LAM), and metabolic diseases such as diabetes and obesity. Given the importance of ... More

PubMed ID:11884416
'Corin is a type II transmembrane serine protease abundantly expressed in the heart. In a previous study using transfected 293 cells, we showed that corin converted pro-atrial natriuretic peptide (pro-ANP) to atrial natriuretic peptide (ANP), suggesting that corin is likely the pro-ANP convertase. Because other serine proteases such as thrombin ... More
Systems survey of endocytosis by multiparametric image analysis.

'Endocytosis is a complex process fulfilling many cellular and developmental functions. Understanding how it is regulated and integrated with other cellular processes requires a comprehensive analysis of its molecular constituents and general design principles. Here, we developed a new strategy to phenotypically profile the human genome with respect to transferrin ... More
N-glycans are direct determinants of CFTR folding and stability in secretory and endocytic membrane traffic.
'N-glycosylation, a common cotranslational modification, is thought to be critical for plasma membrane expression of glycoproteins by enhancing protein folding, trafficking, and stability through targeting them to the ER folding cycles via lectin-like chaperones. In this study, we show that N-glycans, specifically core glycans, enhance the productive folding and conformational ... More
Disinhibition of neurotrophin-induced dorsal root ganglion cell neurite outgrowth on CNS myelin by siRNA-mediated knockdown of NgR, p75(NTR) and Rho-A.
Authors:Ahmed Z, Dent RG, Suggate EL, Barrett LB, Seabright RJ, Berry M, Logan A,
Journal:Mol Cell Neurosci
PubMed ID:15737741
'The presence of multiple axon growth inhibitors may partly explain why central nervous system axons are generally incapable of regenerating after injury. Using RNA interference (RNAi) in dorsal root ganglia neurons (DRGN), we demonstrate siRNA-mediated silencing of components of the inhibitory signalling cascade, including p75(NTR), NgR and Rho-A mRNA, of ...
