Gotta get that rhythm: Researchers find a relationship between sleep cycle, cancer incidence

People who work around the clock could actually be setting themselves back, according to Virginia Tech biologists.

Researchers found that a protein responsible for regulating the body’s sleep cycle, or circadian rhythm, also protects the body from developing sporadic forms of cancers. 

“The protein, known as human period 2, has impaired function in the cell when environmental factors, including sleep cycle disruption, are altered,” said Carla Finkielstein, an associate professor of biological sciences in the College of Science,  Fralin Life Science Institute affiliate, and a Virginia Bioinformatics Institute Fellow.

UWindsor researcher on a roll using natural extracts to fight cancer

 

After finding treatment possibilities in dandelion root extract, biochemistry professor Siyaram Pandey and the students in his lab have discovered a second natural extract that successfully targets cancer cells.

His latest paper shows that extract from the flowering plant long pepper makes cancer cells undergo apoptosis—essentially committing suicide.

Yale team devises ingenious method to attack cancer at its genetic source

Anti-tumor activity resulting from new gene therapy delivery system is captured in red.

MicroRNAs may be tiny — as few as 20 genetic letters, compared to 3 billion in the DNA of a human — but they play a major role in biology, helping to determine which genes are expressed or silenced. In the last 10 years, researchers at Yale and elsewhere have shown they play a major role in formation and spread of tumors.

However, their potential as a target for cancer therapy has not been realized because of a daunting problem that has held back clinical applications of gene therapy: How can you target minute pieces of genetic material locked safely inside the membranes of billions of cells?

Now a multi-disciplinary team of Yale researchers has solved the problem by designing a therapeutic molecule that both targets the acidic microenvironments of tumors and penetrates cells to deliver a therapeutic cargo. The new delivery system effectively killed advanced tumors in mice, the team reports in the Nov. 17 issue of the journal Nature.

“This strategy opens up a new pathway to therapy, not just for the treatment of cancer but for a host of other diseases as well,” said Donald Engelman, a co-author of the paper and the Eugene Higgins Professor of Molecular Biophysics and Biochemistry at Yale. 

The findings were result of an extensive collaboration between labs of Engelman, Peter Glazer, Mark Saltzman and Frank Slack.

Cannabis extract can have dramatic effect on brain cancer, says new research

Experts have shown that when certain parts of cannabis are used to treat cancer tumours alongside radiotherapy treatment the growths can virtually disappear

The new research by specialists at St George’s, University of London, studied the treatment of brain cancer tumours in the laboratory and discovered that the most effective treatment was to combine active chemical components of the cannabis plant which are called cannabinoids.
