This course is design by expert faculty Dr. Deepmala Katiyar for CSIR-NET/JRF Life Sciences Cell Biology. It included Videos content, PDF notes, CSIR-NET PYQs for every class, online CBT. You will get all content in this course given below according to CSIR-NET/JRF. The course is structured using two Units of CSIR-NET (Unit 2-Cellular Organization & Unit 4- Cell communication and cell signaling) selected topics. Unit 2: Cellular Organization A) Membrane structure and function (Structure of model membrane, lipid bilayer and membrane protein diffusion, osmosis, ion channels, active transport, membrane pumps, mechanism of sorting and regulation of intracellular transport, electrical properties of membranes). B) Structural organization and function of intracellular organelles (Protein sorting in mitochondria, Golgi bodies, endoplasmic reticulum). D) Cell cycle (steps in cell cycle, regulation and control of cell cycle). Unit 4: Cell communication and cell signaling B) Cell signaling Hormones and their receptors, cell surface receptor, signaling through G-protein coupled receptors, signal transduction pathways, second messengers, regulation of signaling pathways D) Cancer Genetic rearrangements in progenitor cells, oncogenes, tumor suppressor genes, cancer and the cell cycle, virus-induced cancer, metastasis, interaction of cancer cells with normal cells, apoptosis, therapeutic interventions of uncontrolled cell growth.
