Characterization of chimeric proteins constructed from human epidermal growth factor (EGF) and the Drosophila EGF-receptor antagonist argos.

Abstract:

:The Drosophila argos protein is a natural ligand antagonist of Drosophila EGF receptor (DER), but does not interact with the human EGF receptor (EGFR). With a view to generating a corresponding EGFR antagonist, we, have designed five chimeric proteins featuring selected characteristic parts of argos within the framework of the human EGF ligand. These chimeras were expressed in bacteria, purified, refolded and characterized. We tested their ability to bind to EC;FR, to effect receptor tyrosine phosphorylation and to inhibit EGF-induced EGFR phosphorylation.

  • Expression of microRNA-21 in non-small cell lung cancer tissue increases with disease progression and is likely caused by growth conditional changes during malignant transformation.

    abstract::MicroRNAs can govern up to hundred different mRNAs and are important regulators of gene expression programs in development and disease. We analyzed the expression of microRNA-21, one of the most common oncomirs, in non-small cell lung cancer (NSCLC). Using northern blots the microRNA-21 expression levels of NSCLC-deri...
