1. The Tyrosine Kinase GTK : Signal Transduction and Biological Function
Abstract : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

2. Understanding molecular mechanisms of protein tyrosine kinases by molecular dynamics and free energy calculations
Abstract : Background: Insulin receptor kinase (IRK) and Insulin-like growth factor 1 receptor kinase (IGF-1RK) are two important members in the large class of tyrosine kinase receptors. They play pivotalroles in the regulation of glucose homeostasis, cell proliferation, differentiation, motility, andtransformation. READ MORE

3. Using Light to Regulate the Activity of RET Kinase: Design, synthesis and evaluation of photoswitchable DFG-out RET kinase inhibitors
Abstract : Protein kinases are essential for signal transduction and regulate most cellular processes, such as metabolism, membrane transport, motility, and cell cycle. Although they play a critical role in cells and have a strong association with diseases, details of their physiologic and pathologic mechanisms remain at least partially unclear, especially the spatiotemporal dynamics of the signalling.

4. Receptors for growth hormone and prolactin. Regulation and activation
Abstract : Cytokine receptor activation is dependent on ligand-induced receptor dimerization or oligomerization and subsequent activation of several intracellular proteins. Activation of Janus kinases (Jaks) is probably the first intracellular event that occurs after receptor dimerization. READ MORE

5. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells
Abstract : Insulin stimulation of rat adipocytes results in phosphorylation and activation of the cyclic nucleotide phosphodiesterase 3B (PDE3B), a key enzyme in the antilipolytic signalling pathway of this hormone. In this thesis, the site phosphorylated in PDE3B upon stimulation of rat adipocytes with insulin and/or the beta-adrenergic agonist, isoproterenol is identified. READ MORE
