Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is NOT a role of the tumor suppressor gene?
A
Inhibiting the cell cycle
B
Stimulating repair of damaged DNA
C
Promoting cell adhesion
D
Promoting angiogenesis
Explanation: 

Detailed explanation-1: -Tumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don’t work properly, cells can grow out of control, which can lead to cancer.

Detailed explanation-2: -Answer and Explanation: Which of the following is not a tumor suppressor gene? The answer is a. RET.

Detailed explanation-3: -Among the most commonly described angiogenic growth factors and cytokines include vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), tumor necrosis factor-alpha (TNF-), transforming growth factor-beta (TGF-), and the angiopoietins (Ang).

Detailed explanation-4: -Angiogenesis plays a critical role in the growth of cancer because solid tumors need a blood supply if they are to grow beyond a few millimeters in size. Tumors can actually cause this blood supply to form by giving off chemical signals that stimulate angiogenesis.
