Water channels exist not only in nature — microscopical water channels are also present in the cells of the body, where they ensure that water can be transported through the protective surface of the cell. Scientists at the University of Gothenburg, Sweden, have discovered that one type of the body's water channels can be modified such that it becomes more stable , which may be significant in the treatment of several diseases. "It's important to understand how the water channels,...

New research in the FASEB Journal suggests that aquaporin-4, a water transporting protein, plays a role in brain inflammation via a mechanism involving astrocyte swelling and cytokine release A new protein, called aquaporin-4, is making waves and found to play a key role in brain inflammation, or encephalitis. This discovery is important as the first to identify a role for this protein in inflammation, opening doors for the development of new drugs that treat brain inflammation and other...

Research by University of Warwick's School of Life Sciences has opened up a new path to produce water efficient seeds that will be a significant tool to help create drought resistance, and ensure global food security.  The research not only provides the best map to date of the key protein that appears to be the principal gateway for water intake during seed germination - it also actually provides the right map as it appears much of the research to date was focussed on a much less...

LONDON, March 10 /PRNewswire/ -- Based on its recent analysis of the biomimetic membranes market, Frost & Sullivan recognises Aquaporin A/S with the "2009 European Biomimetic Membranes Technology Innovation Award." The demand for high-purity water separation across a wide variety of industries is likely to establish Aquaporin Membranes, a novel biomimetic membrane that is embedded with aquaporins, as the standard equipment for membrane separation.

New research reveals how proteins that are critical for the transparency of the eye lens are properly sorted and localized in membrane bilayers. The study, published by Cell Press in the November 3rd issue of Biophysical Journal, analyzes how interactions between lipid and protein molecules can selectively concentrate proteins in certain regions of the cell membrane. All cells are surrounded by a dynamic semi-permeable structure called the plasma membrane. Cell plasma membranes are made of a...

The flow of water into and out from the cell may play a crucial role in several types of cancer. Scientists at the University of Gothenburg have now found the gate that regulates the flow of water into yeast cells. The discovery, which will be published in the journal PLoS Biology, raises hopes of developing a drug that inhibits the spread and growth of tumors.All living organisms must be able to regulate the flow of water into and out from cells, in order to maintain cell form and size. This...

Water is a crucial ingredient for life, but its level inside cells must be carefully regulated to maintain proper cell shape and size. In this week's issue of the open access journal PLoS Biology, scientists from the University of Gothenburg describe the highest resolution three-dimensional structure yet of a membrane protein, in this case of a protein channel known as an aquaporin that regulates water flow into and out of yeast cells. Virtually all living organisms use aquaporins to regulate...

San Diego -- Researchers have identified a molecular suspect in a disorder similar to multiple sclerosis (MS) that attacks the optic nerve and spinal cord, according to a report presented at the 130th annual meeting of the American Neurological Association in San Diego. The protein, called aquaporin-4, is a channel protein that allows water to move in and out of cells. "Aquaporin-4 is the first specific molecule to be defined as a target for the autoimmune response in any form of MS," said...

CHAMPAIGN, Ill. -- For a glycerol molecule, a measly angstrom's difference in diameter is a road-closed sign: You can't squeeze through unless you are a sleek, water-molecule-sized sports car, say scientists at the University of Illinois at Urbana-Champaign. The roadway is in aquaporins, a class of proteins that form trans-membrane channels in cell walls in all forms of life. They allow for water movement between the cell and its environment. A subfamily of aquaporins allows slightly larger...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
