How do tumor suppressor genes cause cancer
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 … WebTumor suppressor genes are segments of DNA that code for negative regulator proteins, which keep the cell from undergoing uncontrolled division. Mutated p53 genes are believed to be responsible for causing tumor growth because they turn off the regulatory mechanisms that keep cells from dividing out of control.

WebP53 is a tumor suppressor gene, a gene that has the ability to prevent cancer but not allowing the cell to divide (Weinberg 2014). P53 is considered the “guardian of the genome” due to its variety of functions that are crucial for regular cell life cycles, and can prevent cancer (Weinberg 2014).
