| Posted: 23 Jan 2012 02:57 PM PST A recent study investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases.  |
| Researchers develop gene therapy that could correct a common form of blindness Posted: 23 Jan 2012 01:34 PM PST A new gene therapy has the potential to treat a common form of blindness that strikes both youngsters and adults. The technique works by replacing a malfunctioning gene in the eye with a normal working copy that supplies a protein necessary for light-sensitive cells in the eye to function. Several complex steps remain before the gene therapy technique can be used in humans, but once at that stage, it has great potential to change lives.  |
| Study shines light on ways to cut costs for greenhouse growers Posted: 23 Jan 2012 12:25 PM PST Greenhouse bedding plant growers can save themselves time, money or possibly both by giving cuttings in propagation more light, according to a new study.  |
| Gene therapy cures retinitis pigmentosa in dogs Posted: 23 Jan 2012 12:25 PM PST Scientists have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs. The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man.  |
| Compounds in mate tea induce death in colon cancer cells, in vitro study shows Posted: 23 Jan 2012 08:55 AM PST In a recent study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of mate tea, which has long been consumed in South America for its medicinal properties.  |
| Saving the snow leopard with stem cells Posted: 23 Jan 2012 06:47 AM PST The survival of the endangered snow leopard is looking promising thanks to scientists who have, for the first time, produced embryonic stem-like cells from the tissue of an adult leopard.  |
| Posted: 23 Jan 2012 06:44 AM PST The same mechanism that stabilizes the DNA in the cell nucleus is also important for the structure and function of vertebrate muscle cells. An enzyme attaches a methyl group to the protein Hsp90, which then forms a complex with the muscle protein titin. When the researchers disrupted this protein network through genetic manipulation in zebrafish the muscle structure partly disintegrated. The scientists have thus shown that methylation also plays a significant role outside the nucleus.  |
