Investigators report non-coding miRNAs as appealing biomarkers for cancer malignancy

As many as 50 percent of all human protein-coding genes are regulated by microRNA (miRNA) molecules. While some miRNAs impact onset and progression of cancer, others can actually suppress the development of malignant tumors and are useful in cancer therapy. They can also serve as potential biomarkers for early cancer detection. In a new issue of Cancer Biomarkers, investigators report on non-coding miRNAs as appealing biomarkers for malignancy.

Link made between muscular dystrophy and defective nerve wiring

Working with mice, Johns Hopkins scientists have discovered that a particular protein helps nerve cells extend themselves along the spinal cord during mammalian development. Their results shed light on the subset of muscular dystrophies that result from mutations in the gene that holds the code for the protein, called dystroglycan, and also show how the nerve and muscle failings of the degenerative diseases are related.

Researchers uncover mechanism that switches off cell transport regulating proteins

Researchers at the RUB and from the MPI Dortmund have uncovered the mechanism that switches off the cell transport regulating proteins. They were able to resolve in detail how the central switch protein Rab is down-regulated with two "protein fingers" by its interaction partners.

Ion channel acts as powerful ‘brake’ after epileptic seizures

Given that epilepsy impacts more than 2 million Americans, there is a pressing need for new therapies to prevent this disabling neurological disorder. New findings from the neuroscience laboratory of Mark S. Shapiro, Ph.D., at The University of Texas Health Science Center at San Antonio, published Dec. 20 in the high-impact scientific journal, Neuron, may provide hope.

New form of puffed rice ideal for breakfast cereals and snacks

A new process for blowing up grains of rice produces a super-nutritious form of puffed rice, with three times more protein and a rich endowment of other nutrients that make it ideal for breakfast cereals, snack foods and nutrient bars for school lunch programs, scientists are reporting. Their study appears in ACS' Journal of Agricultural and Food Chemistry.

MiR-122 plays a critical role in the life cycle of hepatitis C virus

Hepatitis C virus has evolved to invade and hijack the basic machinery of the human liver cell to ensure its survival and spread. Researchers at the University of North have discovered how hepatitis C binds with and repurposes a basic component of cellular metabolism known as a microRNA to help protect and replicate the virus.

High AngII levels put stress on the ER and cause hypertension

When the heart works too hard, the brain may be to blame, says new Cornell University research that is changing how scientists look at high blood pressure (hypertension). The study, published in the Journal of Clinical Investigation in November, traces hypertension to a newfound cellular source in the brain and shows that treatments targeting this area can reverse the disease.
