Bioartificial kidney under study at MCG

... immune system. The new device for kidney failure adds billions of kidney cells that can perform many of these important kidney functions. Human proximal tubule cells are collected from kidneys obtained by the National Disease Research Interchange, a nonprofit organization that provides researchers with ...

New binding target for oncogenic viral protein

...protein is part of a ubiquitin ligase complex that adds ubiquitin to proteins to mark them for destruction by the cell. Fbw7 recognizes a destruction signal on certain proteins that need to be degraded and brings them in close proximity to the enzymes that attach ubiquitin. The proteins recognized by Fbw7...

Lack of enzyme turns fat cells into fat burners

...rts become obese and develop type 2 diabetes."This adds another tissue or organ that helps out in the process ofenergy maintenance," said Wakil. "ACC2 is potentially a key enzyme inthe regulation of weight, obesity, and related problems."Wakil and his colleagues studied the oxidation of fatty acid andgluc...

Newly-discovered class of genes determines ?and restricts ?stem cell fate

...Pax3 is known to be involved in some tumors, which adds evidence to the stem-cell origin for some cancers. This theory proposes that many cancers may arise from normally scarce resident stem cells that grow uncontrollably, rather than from the vast majority of differentiated cells that make up organs wher...

Timing is everything: First step in protein building revealed

...r laboratory experiments that is clearlythe case," adds Lorsch. "Even if it isn't released completely in intactcells, our results would indicate that it must be very looselyassociated for translation [protein building] to begin."To monitor what was happening to eIF1, the researchers tagged it and arelated...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

Learning to fight an adversary that won't stay down

...eld solutions to the problem, says Dr. Davies. He adds that our understanding of the activity of microbes must extend beyond the newspaper headlines reporting outbreaks of these "superbugs," so that we can put the role of these organisms in the proper evolutionary perspective. This subject, and antibioti...

Novel Enzyme Shows Potential As An Anti-HIV Target

...ominently in this regulation is acetylation, which adds an acetyl group (a molecule made of oxygen, hydrogen, and carbon) to a molecule or protein. Histone acetylation was long thought to influence transcription by regulating the structure and function of chromatin, which is an assembly of proteins (mostl...

Researchers reveal the infectious impact of salmon farms on wild salmon

...stigate the degree of impact on wild populations," adds Krkosek. The authors concur that their findings point to a need to reconsider the premise of industrial scale fish farming in wild salmon habits. "There's a double bottom line here. The full ecological costs of industrial scale salmon farming must b...

Gene Vaccine Protects Mice Against Development Of Her2/neu Breast Cancer

Newly Discovered Compound Blocks Known Cancer-Causing Protein

...r key player in the pathway, the Icmt enzyme. Icmt adds a chemical tag called a "methyl group" to Ras. This methyl tag enables Ras to be directed to its final destination in the cell, from where it can send signals for unchecked growth. "Ras needs to be at the plasma membrane in order to function," he sa...

She adds that, "Memory impairment in wild animals would undoubtedly have severe implications for survival, for example remembering nest sites, food sites and predator vicinities, as well as for fitness, for example remembering territories and potential mate l...

NASA links nanobacteria to kidney stones and other diseases

...solve this puzzle, but we feel that we are close," adds Ciftcioglu. NB was discovered in the 1990s and has been found in the calcium phosphate centers of kidney stones. This novel agent has also been detected in related conditions, including Alzheimer's disease, heart disease, prostatitis, and some cance...
