Part 2 Flashcards
In a study on women with colorectal cancer, what association was there with telomere length?
There was a U shaped curve. In other words, there was an increased risk for colorectal cancer with telomeres that were too long or too short

What organs is carnosine primarily found in?
Brain and muscle, less in the heart, liver and kidneys as well as some other organs. It is primarily found in red meat.
What is the MOA of carnosine?
It decreases glycation and cross-linking of proteins. It is also an antioxidant.
What effect did carnosine have on human diploid fibroblasts?
It decreased the rate of telomere shortening and damage
What effect did carnosine have on fruit flies in one study?
It increased the lifespan of male fruit flies by 16% and female fruit flies by 36%
What effect does carnosine have on lipids?
It decreases oxidative stress
What effect does carnosine have on platelet aggregation?
It decreases platelet aggregation in patients with a high clotting index and increases platelet aggregation in patients with a low clotting index
What effect does carnosine have on cataracts and skin?
It decreases cataract formation and decreases skin aging
Carnosine + what is used to treat peptic ulcers?
Zinc
what effect does carnosine have on exercise?
It increases muscle strength and endurance
What is the typical dose of carnosine supplementation?
