Studying blood sugar regulation in cavefish has implications for understanding human diabetes

Mar 21 2018

KANSAS CITY, MOUnderstanding how cavefish have adapted to their extreme environments and how their metabolism is different from surface fish may be relevant for understanding metabolism-related conditions in humans. Stowers Assistant Investigator Nicolas Rohner, PhD, and colleagues at Stowers and Harvard Medical School recently published findings in Nature that suggest how cavefish have acquired biological mechanisms to compensate for detrimental effects of high blood sugar levels, which are characteristic of some human metabolic disorders such as diabetes.
