Is their a link between sugar consumption and cancer? Scientists may finally be able to explain how tumors grow!

Previously, it was a topic of debate whether Warburg Effect was a symptom of cancer, or a cause of cancer.

Belgium, October 28, 2017: Is your sugar consumption causing, or spreading cancer in your body?

A new study published in the journal Nature Communications claims to have found the connection between sugar and cancer and scientists may finally be able to explain how tumors grow.

The nine-year-old study has revealed that cancer cells break down sugars at a faster rate than other cells which consequently stimulates the growth of tumors.

Scientists Study the Warburg Effect

Belgian scientists Veerle Janssens, Wim Versées and Johan Thevelein from VIB, KU Leuven, and Vrije Universiteit Brussel had first begun researching about sugar’s potential link to cancer in 2008 in an attempt to understand the Warburg Effect.

The Warburg Effect: First observed in 1924 by Otto Warburg, the Warburg Effect is a prominent feature of cancerous cells and if often put to use to detect brain tumors.

In simple terms, tumor cells make energy by rapidly breaking down proteins, which is not seen in normal cells. It is this energy that is fueling the growth of tumors.

The Study

For their research, scientists used yeast as a model organism as, like cancer cells, it employs a similar mechanism to produce energy from sugar- through fermentation.

Yeast also contains the ‘Ras’ proteins that are also found in cancer.

Ras proteins are known to control the growth of cells in our body. If the genes that control Ras proteins mutate, they can cause an increased cell growth and an intensive production of cancer cells.

Thus, using yeast, the Belgian researchers analyzed the link between high sugar metabolism and Ras.

What Did The Study Reveal?

All cells in the body require sugar, but research has found that cancerous cells consume more sugar when compared to normal cells, breaking it down into glucose, which is then fermented into lactic acid. It is this fermentation that aids the spread of the tumor.

Previously, it was a topic of debate whether Warburg Effect was a symptom of cancer or a cause of cancer. The new study has revealed that it actually aids and stimulates cancerous tumors. However, this does not necessarily mean that sugar is causing cancer.

Explaining the “strength of the Warburg effect and tumor aggressiveness”, the study explains the consequences of the interaction of cancerous cells with sugar.

While these findings are monumental, scientists are not calling it a medical breakthrough. According to Prof. Johan Thevelein from KU Leuven in Belgium, the study will provide a foundation for future cancer research which will hopefully yield precise results.

World’s Smallest Wearable Can Help in Preventing Skin Cancer

It also demonstrated the ability to measure white light exposure for seasonal depression, a mood disorder characterised by depression that occurs at the same time every year

Scientists have developed the world’s smallest wearable, battery-free device that can warn people of overexposure to ultraviolet rays (UV) — a leading factor for developing skin cancer.

Currently, people do not know how much UV light they are actually getting. The rugged and waterproof device interacts wirelessly with the phone and helps maintain an awareness and for skin cancer survivors.

Smaller than an M&M (colourful button-shaped chocolates) and thinner than a credit card, the device can optimise treatment of neonatal jaundice, skin diseases, seasonal affective disorder and reduce risk of sunburns and skin cancer.

Users can glue the device on to their hats, clip it to sunglasses or stick it on their nail and can simultaneously record up to three separate wavelengths of light.

It is always on yet never needs to be recharged.

“There is a critical need for technologies that can accurately measure and promote safe UV exposure at a personalised level in natural environments,” said Steve Xu, from Northwestern University in the US.

“We hope people with information about their UV exposure will develop healthier habits when out in the sun,” said Xu.

There are no switches or interfaces to wear out, and it is completely sealed in a thin layer of transparent plastic, the researchers stated, in the paper published in the journal Science Translational Medicine.

Participants who mounted device on themselves recorded multiple forms of light exposure during outdoor activities, even in the water.

The findings showed that it monitored therapeutic UV light in clinical phototherapy booths for psoriasis and atopic dermatitis (immune diseases) as well as blue light phototherapy for newborns with jaundice in the neonatal intensive care unit.

It also demonstrated the ability to measure white light exposure for seasonal depression, a mood disorder characterised by depression that occurs at the same time every year. (IANS)
