“The new study lays the groundwork for developing treatments for diseases such as asthma, COPD, cystic fibrosis and even certain cancers,” said senior author Thomas J. Brett, PhD, assistant professor of medicine. “It also solves a 20-year mystery about the role of a protein that has long been associated with these diseases.” The study appears March 17 in the journal eLife. …
A membrane channel is a family of proteins that allows the movement of ions, water or other solutions to pass through the membrane. These findings are being published in the Nov. 10, 2014, edition of the journal Cancer Cell. …
Telomeres stay intact in most cancer cell types by means of a specialized enzyme called telomerase that adds the repetitive telomere DNA sequences to the ends of chromosomes. Cancer cells can also use a second method involving a DNA-repair-based mechanism, called alternative lengthening of telomeres, or ALT for short. In general, cancer cells take over either type of telomere maintenance machinery to become immortal…

"The brain can be mapped by tracking the movement of its water molecules," said Clark Chen, MD, PhD, neurosurgeon and vice-chairman of neurosurgery at UC San Diego Health System. "Water molecules in brain nerves move in an oriented manner…
How can you tell if a breast tumor is malignant? This isn’t a question that ultrasound and X-rays, or even magnetic resonance scans, can answer alone. Doctors must often extract tissue samples from an affected area with a fine needle for detailed examination…
The concept involves using nanoparticles made of "weak polybases," compounds that expand when transported into environments mimicking tumor cells, which have a higher acidity than surrounding tissues. …
The ability of cells to move and change shape is significant in many biological processes. White blood corpuscles gather at "hotspots" like infections and inflammations. Stem cells in the embryo move off in different directions to make the organs of the body. One unwanted movement is the movement of tumour cells, which lead to cancer metastasis…
