New Delhi:

Paving the path for novel targeted therapies to treat the deadliest disease cancer, a new study has discovered that some types of cancers are more sugar hungry than others and fuel themselves from the glucose of our body.

University of Texas at Dallas in the US stated the research with the aim to find differences between the metabolism of two sub types of non-small cell lung cancer- Adenocarcinoma (ADC) and Squamous cell carcinoma (SqCC).

Talking about their study Jung-whan Kim, one of the assistant professor of the university said, "It has been suspected that many cancer cells are heavilydependent on sugar as their energy supply, but it turns out that one specific type - squamous cell carcinoma- is remarkably more dependent".

About one quarter of all lung cancers are SqCC, which has been difficult to treat with targeted therapies. Researchers tapped into a large database of about 33 types of cancer gathered from more than 11,000 patients.

They found that a protein responsible for transporting glucose into cells was present in significantly higher levels in lung SqCC than in lung ADC. The protein, called glucose transporter 1 (GLUT1) takes up glucose into cells, where the sugar provides a fundamental energy source and fuels cell metabolism, researchers said.

With elevated GLUT1 implicated in SqCC's appetite for sugar, researchers looked for additional evidence by examining human lung tissue and isolated lung cancer cells, as well as animal models of the disease.

"We looked at this from several different experimental angles, and consistently, GLUT1 was highly active in the squamous subtype of cancer.

Adenocarcinoma is much less dependent on sugar," said Kim, senior author of the studypublished in the journal Nature Communications.

Researchers also investigated the effect of a GLUT1 inhibitor in isolated lung cancer cells and mice with both types of non-small cell lung cancer.

"When we gave GLUT1 inhibitors to mice with lung cancer, the squamous cancer diminished, but not the adenocarcinoma.

There was not a complete eradication, but tumour growth slowed," researchers said.

The team also found that GLUT1 levels were much higher in four other types of squamous cell cancer: head and neck, esophageal and cervical.

These are very different organs and tissues in the body, but somehow squamous cell cancers have a very similar commonality in terms of glucose uptake, researchers said.

This type of cancer clearly consumes a lot of sugar. One of our next steps is to look at why this is the case, they said.

"As a culture, we are very addicted to sugar. Excessive sugar consumption is not only a problem that can lead to complications like diabetes, but also, based on our studies and others, the evidence is mounting that some cancers are also highly dependent on sugar," Kim said.

"We'd like to know from a scientific stand point whether we might be able to affect cancer progression with dietary changes," Jung-whan Kim stated further.
