How Pancreatic Cancer is Linked to Athletic Performance?

High Fat Diet May Boost The Growth Of Cancer Cells In Pancreas

PPARδ regulates the expression of a wide spectrum of key genes that influences biological processes like lipid metabolism and cancer formation. Activation of PPARδ dramatically accelerates the progression of pre-cancerous lesions into pancreatic cancer.

“We became interested in studying the effects of PPARδ on pancreatic carcinogenesis because our prior observations showed that PPARδ strongly promoted other gastrointestinal cancers. But there’s very limited information about PPARδ’s role in pancreatic cancer’s development,” said Shureiqi.

Activation of PPARδ correlates with high-fat diets, which have been associated with increased risk for pancreatic cancer in humans and animal models. High-fat diets are enriched with fatty acids that are natural ligands of PPARδ.

Other synthetic forms of PPARδ ligands are found in exercise supplements, aimed to boost physical performance and endurance.

These supplements were originally designed by pharmaceutical companies to encourage the body to use more fat and treat noncancerous conditions like obesity and hyperlipemia. Later, many companies have discontinued given their potential precancerous side effects.

Though studies on how PPARδ affects colorectal cancer date back to 1999, and pharmaceutical companies have halted synthetic PPARδ ligand development, unregulated internet outlets still sell substances like Cardarine. Ads are largely marketed to young people, claiming it will help them build muscle endurance and burn fat.

Muscle Enhancers Enhances Stamina Along With Cancer Risk

Initially, researchers found that these supplements reduced fatigue in mice. This news made its way to major media outlets, who nicknamed it “exercise in a pill”.

Unfortunately, what the media didn’t address was the dark side of it. Like muscle cells, synthetic PPARδ ligands also help cancer cells get more energy from fats as a fuel source.

Animal models repeatedly show the strong relationship between PPARδ and cancer promotion in the case of colorectal cancer and stomach cancer. Now we’re gaining more information about how it affects pancreatic cancer.

Future development of effective agents to block PPARδ activation could be a new approach to prevent the progression of precancerous lesions into pancreatic cancer.

Limiting exposure to high-fat diets could also be considered for those with a high prevalence of pre-cancerous pancreatic lesions. But for now, the prevalent sales and use of those athletic boosting substances cause the most pressing concern.

We are trying to spread the message that using those substances is not a good idea. It might enhance muscle endurance, but it also enhances cancer’s ability to use energy and grow.
