Scientists engineer novel protein working like a guided missile to destroy cancer cells
Q. Scientists have engineered novel proteins working like _______________ to seek out cancer cells and deliver chemotherapy drugs.- Published on 20 Jun 16a. Guided missiles
b. Guided rockets
c. Guided drones
d. None of the above
ANSWER: Guided missiles
Scientists have worked out novel proteins that work like guided missiles which seek cancel cells and deliver chemotherapy drugs to cure had to reach tumours without harming healthy cells.
- Chemotherapy drugs do kill cancer cells, they damage other quickly dividing cells in the human body causing everything from cosmetic to disabling impact
- Drug dose needed to kill tumour may be more than what the human body can handle
- Dose high enough to infiltrate the tumour could also harm other cells in the human body
- Recently approved therapies deliver drugs directly to the tumours
- Now, researchers are using engineered protein rather than antibodies to direct drug to the tumour
- Specialised protein reaches out faster and is smaller in size than antibodies. Big size limits penetration by antibodies. Smaller molecule could diffuse into the tumour better.
