Chilli Can Serve As A Valuable Medicine in Case of Lung Cancer

Additional experiments revealed capsaicin suppresses lung cancer metastasis by inhibiting activation of the protein Src. This protein plays a role in the signalling that controls cellular processes like proliferation, differentiation, motility and adhesion.

Besides spicing up your food, chilli, it seems, also has some medicinal value. New research suggests the compound responsible for chilli’s heat could help slow the spread of lung cancer, the leading cause of cancer death for both men and women.

Most cancer-related deaths occur when cancer spreads to distant sites, a process called metastasis.

“Lung cancer and other cancers commonly metastasise to secondary locations like the brain, liver or bone, making them difficult to treat,” said one of the study authors Jamie Friedman from Marshall University in the US.

“Our study suggests the natural compound capsaicin from chilli peppers could represent a novel therapy to combat metastasis in lung cancer patients,” said Friedman, a doctoral candidate who performed the research in the laboratory of Piyali Dasgupta at Marshall University Joan C. Edwards School of Medicine.

The findings were presented during the 2019 Experimental Biology meeting being held from April 6-9 in Orlando, Florida.

“We hope one day capsaicin can be used in combination with other chemotherapeutics to treat a variety of lung cancers,” said Friedman. (IANS)

Parkinson Treatment Possible Through A Blood Pressure Drug

Felodipine was effective at reducing the build-up of "aggregates" in mice with the Huntington's and Parkinson's disease mutations and in the zebrafish dementia model.

"This is the first time that we're aware of that a study has shown that an approved drug can slow the build-up of harmful proteins in the brains of mice using doses aiming to mimic the concentrations of the drug seen in humans," said Professor Rubinsztein. Pixabay

Felodipine, a prescribed drug to treat high blood pressure, has shown promise against Parkinson’s, Huntington’s and forms of dementia in studies carried out in mice and zebrafish at the University of Cambridge.

In a study published in the journal Nature Communications, scientists have shown in mice that felodipine may be a candidate for re-purposing.

A common feature of neurodegenerative diseases is the build-up of misfolded proteins.

These proteins, such as huntingtin in Huntington’s disease and tau in some dementias, form “aggregates” that can cause irreversible damage to nerve cells in the brain.

A team led by Professor David Rubinsztein used mice that had been genetically modified to express mutations that cause Huntington’s disease or a form of Parkinson’s disease, and zebrafish that model a form of dementia.

Felodipine was effective at reducing the build-up of “aggregates” in mice with the Huntington’s and Parkinson’s disease mutations and in the zebrafish dementia model.

The treated animals also showed fewer signs of the diseases.

“This is the first time that we’re aware of that a study has shown that an approved drug can slow the build-up of harmful proteins in the brains of mice using doses aiming to mimic the concentrations of the drug seen in humans,” said Professor Rubinsztein.

In healthy individuals, the body uses a mechanism to prevent the build-up of such toxic materials.

This mechanism is known as autophagy, or ‘self-eating’, and involves cells eating and breaking down the materials.

“This is only the first stage, though. The drug will need to be tested in patients to see if it has the same effects in humans as it does in mice. We need to be cautious, but I would like to say we can be cautiously optimistic,” said Professor Rubinsztein. (IANS)
