Tagish Lake Meteorites Help Solve Amino Acid Mysteries
2012-07-26 14:48:28

Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...

New method less prone to contamination, provides further insight into immune response A 500-year-old frozen Incan mummy suffered from a bacterial lung infection at the time of its death, as revealed by a novel proteomics method that shows evidence of an active pathogenic infection in an ancient sample for the first time. The full report is published July 25 in the open access journal PLoS ONE. Detecting diseases in ancient remains is often fraught with difficulty, especially because of...

The research provides insights into programmed cell death and opens door to new approaches to cancer treatment Scientists at The Scripps Research Institute have simultaneously mapped two of the most important types of protein-modification in cells, revealing their extensive cooperation during an essential cellular process. Phosphorylation, the attachment of a phosphate group to a protein, and proteolysis, the cleavage of a protein, had almost always been studied independently. The new...

Researchers from the Hebrew University of Jerusalem and the Weizmann Institute of Science have developed a technique to cause apoptosis, or programmed cell death, that could lead to new approaches to treating cancer. Apoptosis is an essential defense mechanism against the spread of abnormal cells such as cancer. It is a complex process that occurs through networks of proteins that interact with each other. Cancer cells usually avoid this process due to mutations in the genes that encode...

'Paper of the week' shows that a master regulator protein brings plethora of coactivators to gene expression sites Molecular geneticists call big boss proteins that switch on broad developmental or metabolic programs "master regulators," as in master regulators of muscle development or fat metabolism. One such factor, the Activating Transcription Factor 6α (ATF6α) protein, takes charge following a cellular crisis known as endoplasmic reticulum (ER) stress,...
