WebHow is a normal cell transformed into a cancer cell? Proteins involved in the regulation of cell division events no longer promote progression from one phase of the cell cycle appropriately. Instead of developing fully to perform functions, cancer cells reproduce at rates far beyond the usual tightly regulated boundaries of the cell cycle. WebTumour suppressor genes, like proto-oncogenes, are involved in the normal regulation of cell growth; but unlike proto-oncogenes, which promote cell division and differentiation, tumour suppressors restrain them. If proto-oncogenes are the accelerators of cell growth, tumour suppressor genes are the brakes.
