PI3K pathway

The PI3K pathway is a critical communication network within cells that helps regulate growth, survival, and metabolism. When certain signals, like growth factors, bind to the cell's surface, they activate PI3K enzymes. These enzymes trigger a series of steps that lead to the production of molecules promoting cell survival and growth. Proper functioning of this pathway is essential for normal development, but when it becomes overactive, it can contribute to diseases like cancer by allowing cells to grow uncontrollably. Therefore, the PI3K pathway is a key focus for developing targeted therapies in medicine.
