Tumor Angiogenesis Prevention Strategies Quiz

What is the primary role of VEGF in tumor angiogenesis?

• To destroy blood vessels

• To promote the growth of new blood vessels towards the tumor

• To inhibit oxygen supply to the tumor

• To increase the size of the tumor cells

How do antibodies against VEGF help in preventing tumor growth?

• By promoting the growth of new blood vessels

• By binding to VEGF and preventing it from attaching to its receptors

• By destroying tumor cells directly

• By increasing the oxygen supply to the tumor

What is a potential downside of using VEGF receptor blockers?

• They can block other receptor tyrosine kinases, affecting other cell signaling pathways

• They increase the growth of blood vessels

• They are ineffective in all cases

• They are highly specific and only target tumor cells

What is the function of soluble receptors, also known as VEGF traps?

• To increase the production of VEGF

• To promote the growth of tumor cells

• To destroy VEGF molecules

• To compete with original receptors and bind VEGF, preventing angiogenesis

Which of the following is NOT a strategy discussed for inhibiting tumor angiogenesis?

• Increasing oxygen supply to the tumor

• Blocking VEGF receptors

• Using antibodies against VEGF

• Using soluble receptors to trap VEGF
