Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat-called an arrhythmia-that causes a severe decrease in the pumping function of the heart.
The abnormal FIG-ROS fusion protein has constitutively active kinase activity that causes oncogenic transformation (a transformation from normal cells to cancer cells). Chromosomal inversion s: reversing the orientation of a chromosomal segment.
Oncogenes. Oncogenes cause cells to grow out of control. They promote cancer cell growth. Oncogenes are damaged versions of normal genes called proto-oncogenes proto-oncogenesA normal gene involved in the control of cell growth and division that can mutate (change) and become an oncogene.ur bodies are made up of many tiny units called cells, which are arranged into tissues and organs. Tissue and organ growth (in children) and repair (in adults) are generally the result of cells growing in size and dividing into 2 cells in a controlled manner.
