    Cell signalling: how signals are received and transmitted within cells. Steroid hormone and redox signalling. Regulation of growth, development and cell death. Diseases associated with aberrant cell signalling.

    For cells to survive and perform their many required functions they need to respond to a vast array of signals. These signals are transmitted through crosstalk between proteins within the cell via various protein modifications and interactions which eventually convert the signal to an appropriate downstream response. Failure to do so invariably results in cellular dysfunction and disease.

    BIOC 353 explores the biochemical and molecular basis of cell signalling pathways. Key pathways required for cellular function will be explored with an emphasis on the diversity of post translational modifications and protein interactions required to effect signals within cells. Pathways to be explored include those involved in growth and development, molecular trafficking, metabolic responses, cell death, inflammatory and oxidative stress responses. Throughout the course, examples of where defective cellular signalling results in disease including cancer, metabolic, neurodegenerative and some rarer diseases will be given. The targeting of cell signalling molecules for therapeutics will also be explored.
