Researchers show key protein necessary for normal development of red blood cells

...ay that involves the interaction of many molecular players and proteins. In humans, there are four globin genes clustered on chromosome 11 in the order in which they are "turned on" or expressed. These genes include the epsilon-globin gene, two gamma-globin genes and the beta-globin gene. Lloyd said that d...

Discovering the first steps in transcription-coupled repair

...e Berkeley National Laboratory, has discovered new players in the first steps of transcription-coupled repair (TCR), an essential but still mysterious mechanism of DNA repair. If a blockage occurs when genetic information from a cell's DNA is being transcribed into RNA -- an activity vital to the synthesis ...

Twin molecular scissors link creation of microRNAs with gene-silencing

...eager to know more about miRNAs, clearly important players on the genetic field despite having gone unnoticed for so long. How are they produced? And how do they work? In a series of studies published over the past year, a research team at The Wistar Institute has provided considerable insight into the worl...

Mouse study: New muscle-building agent beats all previous ones

...n is not the whole story." The evidence for other players came from experiments with mighty mice themselves. Because these mice don't have any myostatin, any effects of injecting the new agent would come from its effects on other proteins, explains Lee. After five injections over four weeks, mighty mice inj...

A real time look at interactions between RNA and proteins

...ties of these special molecules that make them key players in managing some of the cell's most basic functions. Researchers at the University of Pennsylvania School of Medicine who developed the new technology see this advance as one of the next logical steps in genomics research. Senior author James Eberwin...

Master genetic switch found for chronic pain

.... Runx1 is one of a group of proteins that are key players involved in transmitting external sensory information, like pain and the perception of movement, to the spinal cord. In two other related papers in the same issue, Silvia Arber and colleagues and Tom Jessell and colleagues examine related aspects of ...

Animals can change genes quickly to keep up with viral ingenuity

...ense, and it shows that these genes can be central players in the evolution of host organisms in response to the ever-changing strategies of viral attacks. ...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

... showed that the same immune cells may also be key players in the body's maintenance of the normal healthy brain. Their findings led them to suspect that the primary role of the immune system's T cells (which recognize brain proteins) is to enable the "neurogenic" brain regions (such as the hippocampus) to f...

When good DNA goes bad

...similar areas do not. "If we could understand the players involved in this process, we might be able to prevent the generation of these breaks," says Vasquez. "For example, if certain types of cell stress lead to breaks, we might be able to find ways to reduce those stresses and prevent breaks." ...

Report finds cruise industry is protecting the precious places it visits

The major players in the cruise industry, including cruise lines, local governments and shore operators ?in collaboration with civil society organizations - are taking proactive measures to ensure a sustainable future for cruise tourism while preserving cruise destina...

New insight into machinery of immune cells' 'tentacles'

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

...ible to the human eye, they are collectively major players in the web of ocean life." The Census of Marine Life is a global network of researchers in more than 70 nations engaged in a ten-year initiative to assess and explain the diversity, distribution, and abundance of marine life in the oceans -- past, p...

Blood flow in brain takes a twist, affecting views of Alzheimer's

...ssumption by showing that astrocytes are important players in the process too. Studies by the team in mice show that signaling from astrocytes causes arteries in the brain to expand, bringing about an increase in blood flow. "When we measure blood flow," said Nedergaard, "it may be that we are not measuring...

DOE JGI finishes 100th microbial genome

...sulfur bacteria, Chlorobi, are extremely important players in the global cycling of carbon, sulfur, and nitrogen," said Bryant. "Thanks to DOE JGI, the availability of multiple genome sequences for the Chlorobi has turbocharged our functional genomics studies. This has allowed us to make remarkable progress...

...making these vast numbers of RNA molecules central players in our bodies. Work is also underway in academic and industrial labs around the world to engineer RNA for medical purposes. The engineered molecules, called RNA aptamers, are selected for their ability to bind to particular proteins involved in cer...

FSU biologists uncover mechanisms that shape cells for better or worse

...cytes (unfertilized fruit fly eggs) also are known players in the pathogenesis of those diseases. The research performed by FSU Assistant Professor Wu-Min Deng and doctoral student John S. Poulton in the department of biological science could foster a better overall understanding of polarity and how it dev...
