Bioartificial kidney under study at MCG

...ich are involved in diverse functions ranging from regulating vitamin D to modulating the immune response. "Existing forms of dialysis have only replaced the ability of the kidneys to rid the body of waste products and correct abnormalities in blood chemistry; they don't replace kidney function, " says Dr. Szer...

A new mechanism of regulating RNA degradation

...vestigators now know that it plays a major role in regulating the life span of numerous RNAs, and thus controls gene activity. To better understand what controls the NMD system, Maquat and her postdoctoral fellow, Yoon Ki Kim, Ph.D., used a critical component of the NMD complex, Upf1, as bait in a molecular fi...

Further functionalanalyses will be necessary to map the molecular mechanisms in detail.Besides the Rheumatology Clinic at Uppsala Akademiska Hospital,hospitals in Umeå and Lund, in Sweden, and several hospitals in Finlandas wel...

W.M. Keck Foundation funds study of friendly microbes

...wn chemical compounds that play important roles in regulating the properties of the microbial community and human physiology. To do so, the researchers will use a new type of mass spectrometer with an unprecedented capacity to accurately and rapidly identify these metabolites. "We very grateful to the Keck fou...

New Technique for Tracking Gene Regulators

...so scientists know itis important, particularly in regulating cell differentiation,survival, and the function of nerve cells. But there has been no easyway to screen the entire genome. “We are the first to do a genome-widesurvey,?says Dunn.The problem has been the sheer magnitude of information in the genome:th...

Novel Enzyme Shows Potential As An Anti-HIV Target

...ion was long thought to influence transcription by regulating the structure and function of chromatin, which is an assembly of proteins (mostly histones) and DNA. Another, more widely accepted model proposes that histone acetylation controls transcription by recruiting cofactors required for transcription. Ace...

Study finds more than one-third of human genome regulated by RNA

...he sidelines may be one of theprincipal players in regulating cellular mechanisms. "It's exciting to see how many genes are regulated by microRNAs. We nowknow that this type of gene control is much more widespread thanpreviously appreciated," says Whitehead Member and MIT professor ofbiology David Bartel.Micro...

An HIV Protein Plays a Surprising Role in Gene Activation

...oteins and mechanisms dedicated to the business of regulating gene expression, and retroviruses like HIV have evolved myriad ways of redirecting that machinery to their own benefit. Humans and other eukaryotes have three types of RNA polymerases, each charged with transcribing different types of genetic elemen...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

..." Bradley said. "Their behavior indicates they are regulating oxygen." Bradley and Hetz will next work on developing a comprehensive model of insect breathing. "We'd like to expand our present model to explain all aspects of insect breathing. And we'd like to examine insects that do not show this pattern -- fo...

White blood cell waste disposal system plays critical regulatory role

...ep that is a key component of the feedback circuit regulating the balance between neutrophil production and destruction. The research, published in the March issue of Immunity, suggests that the process for disposal of dying neutrophils is actively linked to neutrophil production. A clear understanding of the p...

Scientists discover that host cell lipids facilitate bacterial movement

...t and modify the functions of proteins involved in regulating actin assembly. PIP2 and PIP3 also prevent capping proteins from binding to the ends of actin filaments, allowing new actin filament assembly. Because Listeria is capable of stimulating actin assembly and PIP2 and PIP3 are known to localize to regio...
