Do Labradors have a missing gene?
Researchers studying 310 Labradors found that many of them were missing all or part of a gene known as POMC, which is known to regulate appetite in some species and to help sense how much fat the body has stored. Without it, the dogs don’t know when they’ve had enough, so they just keep eating and eating.
What is dog POMC?
The POMC gene codes for two proteins, beta-MSH (melanocyte-stimulating hormone) and beta-endorphin. These proteins are thought to play a role in satiety (signaling the brain to end the sensation of hunger once a dog eats a meal).
What is the difference between a Lab and a Labrador?

Why are Labs so greedy?
Labrador dogs are well known for being fond of their food, but new research suggests their greedy nature could be down to genetic mutation.
Why are Labs so hyper?
The biggest reason you might see hyperactive behavior in your Labrador is due to a lack of adequate physical activity and exercise. Labs are a high-energy breed of dog that need a lot of daily activity to meet their physical demands.
Why are Labradors fat?
“What we have found is that some Labradors get fat because they have a deletion in a gene within their brain,” he said. “And this particular gene plays a role in sensing how much fat they have in their body – and so some Labradors don’t know how much fat they have and so keep eating to try to get fatter.”
What is POMC deficiency?
Proopiomelanocortin (POMC) deficiency causes severe obesity that begins at an early age. In addition to obesity, people with this condition have low levels of a hormone known as adrenocorticotropic hormone (ACTH) and tend to have red hair and pale skin.

Why are Labradors so hungry?
Why are Labradors always hungry? A 2016 study at the University of Cambridge found that Labradors’ insatiable appetite might be due to changes in a specific gene, called the POMC gene. When the POMC gene is changed, the chemical messages which tell a Lab when he’s full don’t work properly.
How is POMC treated?
In a new study, therapy with the melanocortin-4 receptor agonist setmelanotide has for the first time brought hope of a normal life to patients with POMC-deficiency. Melanocyte stimulating hormones (MSH) are derived from the post-translational processing of proopiomelanocortin.
What stimulates POMC?
UV induction of POMC expression in mouse skin can be directly controlled by p53, and the mouse POMC promoter is stimulated by p53 in response to UV,95 although p53 is not the main or sole regulator of POMC expression.
