Protein helping muscle cells regenerate post heart attack Identified.
Q. A global research team on 20th September 2015 has identified a protein that helps heart muscles regenerate following a heart attack. What is it called?- Published on 21 Sep 15a. Amino Acid 9
b. Follistatin-like 1
c. Follistatin-like 2
d. None of the above
ANSWER: Follistatin-like 1
A global team of scientists have identified a protein which aids heart muscles cells to regenerate after an attack. Patches using this protein could prevent heart attacks. Researchers identified the protein called Follistatin-like 1 (FSTL1), which can stimulate cultured heart muscle cells to divide. The protein embedded in the path caused heart muscle cells already present within the heart to multiply and re-build the damaged heart and reduce scarring.Heart muscle regeneration and scarring are two major issues that current treatments for heart attacks do not resolve.
After a heart attack, the organ is damaged and scarred, making it harder to pump blood. Sustained pressure causes scarring to spread and ultimately causes heart failure.The researchers therefore developed a therapeutic patch made out of collagen, which was cast with FSTL1 at its core.
