Can blind cave fish Beat Diabetes?

[Editor’s note: This story was updated on Sept. 22, 2017, to state that geneticist Cliff Tabin’s remarks were made as part of his scientific talk.] For months fish that live in dark caves in Mexico go without food.

Can fish cause type 2 diabetes?

Now researchers have discovered these strange creatures have another oddity. To survive their food-scarce environment, the fish have evolved extreme ways of turning nutrients into energy. These features create symptoms like large blood sugar swings that, in humans, are precursors of type 2 diabetes.

Do cave fish get diabetes?

To survive their food-scarce environment, the fish have evolved extreme ways of turning nutrients into energy. These features create symptoms like large blood sugar swings that, in humans, are precursors of type 2 diabetes. But in the fish these changes are adaptations, not a disease. These cave fish lead long and healthy lives.

Are cavefish’s eyesight genes disabled?

But Aniket Gore of the US’s National Institute of Child Health and Human Development and colleagues haven’t found any disabling changes in the DNA sequences of eye development genes in the cavefish. Instead, the genes have been switched off by the addition of chemical tags called methyl groups.

How does seafood affect diabetes risk?

Studies have shown that people who consume less seafood may have a higher chance of developing type 2 diabetes. These findings aren’t all that surprising, considering that increased rates of diabetes are often related to increased rates of obesity, and fish is a very lean food.

Surface fish muscle cells take up more glucose than does cave fish muscle, given the same amount of insulin. Genetic analysis revealed a reason for this: The fish had a unique mutation in the insulin receptor gene, and the change helped the fish gain weight.

How does gene editing affect fish eyesight?

When scientists used the gene editing tool CRISPR-Cas9 to augment the cbsa gene in the embryos of seeing Mexican tetras, the fish developed poor and nonexistent eyesight. The mutation works by harming the vascular system around the eyes, robbing the eyes of sufficient blood flow during embryonic development.
