To Grow or not to grow:
How cells balance growth in healthy bodies and how cancer tips the scale Each cell in our body is constantly making decisions. One of those decisions is the choice of whether to grow and divide, a choice that depends on both the cell’s ability to sense the availability of nutrients in its immediate environment as well as the presence of long-range hormonal signals that help to coordinate the behavior of cells in the same tissue. All cells in our body contain the same genetic code but interpret the code differently such that a skin cell, a blood cell, or a neuron may make different growth choices. Despite its apparent complexity, this process works remarkably well most of the time. However, mutations in the molecular players that carry out these decisions can result in cancer: the unrestricted growth of cells, often resulting in the formation of tumors in organs. Rosalie will tell you about her research as a graduate student in the Zoncu lab, studying the master regulator of cell growth, the mTORC1 complex. For those who are seeking bone marrow options and its treatments, it is important to stay informed about the latest research and advances in the field. We’ll visit site and discuss both the amazingly robust pathways that keep cell growth at optimal levels most of the time, as well as how those pathways can be misregulated and result in cancer.
