How plants avoid feeling the burn

...hor on the paper, contributions from chemistry and biochemistry professors Devens Gust, Tom Moore and Ana Moore of ASU's Center for the Study of Early Events in Photosynthesis were instrumental in the project. "The initial interest was to more fully understand how photosynthesis works," said Fisher. Because our...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...esired physiological outcome by manipulating basic biochemistry was clearly satisfying for Montminy. "What really made this an interesting story is that the molecular mechanism and the biology intersected since we were able to explain how TRB3 made the mice lean," he reflects. "That doesn't happen very often." ...

Unusual mechanism keeps repair protein accurate

...study was led by Zucai Suo, assistant professor of biochemistry and a researcher with the Ohio State University Comprehensive Cancer Center ?Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. The research, published in the July 14 issue of The Journal of Biological Chemistry, provides new i...

New understanding of COX-1 and COX-2 enzymes could revise classification of pain meds

...searchers. The study was initiated to explore the biochemistry associated with COX-2 inhibitors such as Vioxx, Be...s and may lead to a broadened understanding of the biochemistry of common pain medications. It is now pointing toward possible alternatives to drugs like Vioxx and ...

Inside rocks, implications for finding life on Mars

... "It's very difficult to get any insight about the biochemistry of organisms that lived nearly a billion years ago, and this (confocal microscopy and Raman spectroscopy) gives it to you. You see the cells in the confocal microscopy, and the Raman spectroscopy gives you the chemistry. "We can look underneath the ...

Unraveling the viral mechanism

..., Dr. Wah Chiu, professor in the BCM department of biochemistry and molecular biology and director of the National Center for Macromolecular Imaging, and his colleagues, describe how they were able to look beyond the highly symmetrical ball-like surface protein shell of the episilon15 bacteriophage that infects S...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...ription mode to NER," Tainer says. "The structural biochemistry of XPB that we discovered shows an unexpected molecular mechanism by which XPB plays a key role in determining exactly how TFIIH functions, whether in transcription or repair mode." ...

Evolution mystery: Spider venom and bacteria share same toxin

... project is Matthew Cordes, assistant professor of biochemistry and molecular biophysics at the University of Arizona. The toxin is uniquely found in the venom cocktail of brown or violin spiders, including the brown recluse, and in some Corynebacteria. The toxin from the spider's venom can kill flesh at the bit...

Sex chromosome genes influence aggression andmaternal behavior, say UVa researchers

...or," explained Emilie Rissman, PhD, a professor of biochemistry and molecular genetics at UVa, who studied aggression and maternal behavior in genetically engineered mice. "Sex chromosome genes may not be the whole story that determines how aggressive or motherly we are, but they are a partof it." Rissman's work...

Molecular force field helps cancer cells defend against attack

... of human cancers." Steven Frisch, a professor of biochemistry and molecular pharmacology at West Virginia University, said the research raises "the compelling possibility of targeting FAK for a novel cancer therapy." "FAK plays a major role in the survival of tumor cells in their normal attached state, and, wh...

World Trade Center identifications pushed forensic DNA technology

... recent book by Dr. Robert C. Shaler, professor of biochemistry and molecular biology and director of the forensics science major program at Penn State. "As of April 2005, when the process was suspended, we had identified only 1,592 out of the presumed 2,749 who died," said Shaler, the former director of the dep...

Gut protein found to protect against infection and intestinal breakdown

Polymer aids in blood clotting, pointing way to new treatment

...ll cells," said Kornberg, an emeritus professor of biochemistry in Stanford University's School of Medicine. "This acidocalcisome has been identified in cells as diverse as bacteria, the protozoa of tropical diseases and the blood-clotting elements of human blood." Although no longer at Illinois, Docampo said he...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...ho earned bachelor's degrees in honors biology and biochemistry in 2004 from Illinois, studied in Antarctica as an undergraduate with animal biology professors Chi-Hing (Christina) Cheng and Arthur L. DeVries, who discovered AFPs in notothenioids. The research team, which also included Clive W. Evans of the Univ...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

...esearcher and assistant professor of chemistry and biochemistry with the Institute for Cellular and Molecular Biology. "The carbohydrate coating is critical in how your immune system recognizes bacteria." Mahal and graduate student Ken Hsu report their findings in the advance on-line edition and March issue of ...

Wisconsin scientists find a way to make human collagen in the lab

..." says Ronald T. Raines, a UW-Madison professor of biochemistry who, with postdoctoral fellow Frank W. Kotch, authored the new PNAS study. Scientists have been seeking a way to make synthetic collagen for at least 30 years. In clinical settings, human collagen would be preferred over bovine collagen because the...

New possibilities to fight pests with biological means

... below the earth's surface [1]. To understand the biochemistry behind this plant defence, biologists of the Max Planck institute studied corn plants, caterpillars of the species Spodoptera littoralis (Egyptian cotton leaf worm) and parasitic wasps of the species Cotesia marginiventris. Deciphering the complex mi...

'Virus chip' detects new virus in prostate tumors

...is class." DeRisi is a UCSF associate professor of biochemistry and co-leader of the study with Don Ganem, MD, also an HHMI investigator at UCSF and a professor of microbiology and immunology. Klein reported the discovery today (February 24) at the American Society of Clinical Oncology (ASCO) prostate symposiu...

HIV accessory protein disables host immunity via receptor-protein intermediary

...immune surveillance has been compromised. Using biochemistry tests, the researchers were able to show that Vpr does interact with PARP-1 through the glucocorticoid receptor. Vpr hitches a ride on the glucocorticoid receptor, driving glucocorticoid to bind to PARP-1?which, in turn, inactivates it. "Ultimately, ...
