Cancer is a general term that is used to refer to a class of diseases in which a group of cells display uncontrollable growth and invasion of tissue. Most cancers produce a tumour, which can sometimes metastasise to different areas of the body. The study of apoptosis and cancer are quite closely linked because in the disease state the cancer cells have found a way to avoid apoptosis. P53 is an important transcription factor involved in the cell cycle and research into this pathway is a very important area of anti-cancer research. Biosensis offers a range of cell cycle regulator antibodies including a p53 antibody.
