Course objectives
An advanced lecture for MSc and PhD students of biochemistry and molecular biology or chemistry and general biology. Overview of basic types of signaling molecules, receptors, effectors, second messengers, and protein kinases. Mechanisms of signal transduction processes mediated by surface receptors and signaling through intracellular receptors. Interaction of different signal transduction pathways in the control of complex physiological processes.
Syllabus
  • 1. Types of signaling molecules and intercellular signal transduction processes in eukaryots. (Hormones, growth factors, neurotransmitters, cytokines. Endocrine, neurocrine, paracrine, and autocrine communications). 2. Classification of hormones according to the type of receptors and mechanism of their action. (Hierarchical arrangement of the endocrine system. Feedback regulation of the hormone secretion). 3. Metabolism of hormones and basic experimental methods in the study of their actions. (Biosynthesis of peptide and protein hormones. Biosynthesis of the thyroid hormones and their metabolism in tissues. Determination of hormones concentration by RIA or IRMA. Assessment of receptor parameters). 4. Mechanisms of signal transduction mediated by plasma membrane receptors. (Basic types of receptors, effectors, second messengers, and protein kinases. Amplification function of receptor-effector-second messenger-protein kinase cascade). 5. Heterotrimeric G-proteins and their functions. (Mechanism of signal transduction mediated by G-proteins. Basic types of G-proteins, alpha-, beta-, and gamma-subunits. Mechanism of the effects of cholera toxin and pertussis toxin. The use of non-hydrolyzable analogs of GTP in the study of G-proteins function). 6. The most important signal transduction pathways initiated by the interaction of extracellular ligands with the G-protein coupled receptors. (Adenylate cyclase cascade and the mechanism of activation of protein kinase A. Phosphoinositide cascade and activation of protein kinase C). 7. The role of intracellular calcium and calmodulin in signal transduction. (Inositoltrisphosphate and ryanodine receptors. Signaling properties of cADP-ribose. Mechanisms of calcium induced release of calcium). 8. Other signal transduction pathways - guanylate cyclases and NO synthases. 9. Receptor tyrosine kinases (RTKs) and MAP kinase cascade. (Mechanism of action of growth factors receptors. Src and other cytosolic tyrosine kinases. SH2 and SH3 binding domains. MAP kinase cascade). 10. Signaling through intracellular receptors. (Mechanism of action of steroid and thyroid hormone receptors). 11. Super-family of GTPases and their cellular functions. (The GTPase cycle, GNRF and GAP proteins. Comparison of the mechanism of action of the elongation factor EF-Tu and heterotrimeric G-proteins. Ras protein and products of other proto-oncogenes). 12. Adaptation of target cells - desensitization of receptors. "Receptor diseases" - disorders connected with impairments of signal transduction. 13. Convergence, divergence, and crosstalk of diverse signal transduction pathways. 14. Interaction of diverse signal transduction pathways in the regulation of complex physiological processes.
