Prolactin reduces arthritis inflammation

2013-08-01
(Press-News.org) Inflammatory joint diseases such as rheumatoid arthritis are the result of cartilage damage and loss. Chondrocytes are the only cells that are found in cartilage and their death is linked to decreased cartilage health. In this issue of the Journal of Clinical Investigation, Carmen Clapp and colleagues at the National University of Mexico identify prolactin as a potential treatment for inflammatory joint disease. Prolactin treatment prevented chondrocyte death and associated cartilage degradation. In a rat model of inflammatory arthritis, prolactin treatment reduced inflammation, bone erosion, joint swelling, and pain. This study indicates that prolactin therapy has the potential to relieve many symptoms associated with rheumatoid arthritis and other inflammatory-related diseases.

Identification of a molecule linking bone loss and bone formation

2013-08-01
Bone integrity requires skeletal remodeling, which involves both bone formation and resorption. It has been previously shown that the formation of new bone is triggered by degradation of older bone. However, it is unknown how these two processes coordinate for skeletal maintenance. In this issue of the Journal of Clinical Investigation, Sunao Takeshita and colleagues at the National Center for Geriatrics and Gerontology identify a protein, CTHRC1 that is secreted by bone adsorbing cells (osteoclasts) and helps initiate bone formation. The authors found that CTHRC1 secretion ...

Defense against bacterial infection in chronic granulomatous disease

2013-08-01
Patients suffering from chronic granulomatous disease (CGD) are prone to recurrent and potentially life threatening bouts of infection due to the inability of phagocytic cells to kill invading microorganisms. Normal phagocytes release reactive oxygen compounds in response to infection, but this defense is lacking in phagocytes of people with CGD. In the current issue of the Journal of Clinical Investigation, Griffin Rodgers and colleagues at the National Institutes of Health identify a neutrophil granule protein, OLFM4 as a potential therapeutic target for CGD patients. ...

We each live in our own little world -- smellwise

2013-08-01
There are some smells we all find revolting. But toward a handful of odors, different people display different sensitivities—some can smell them, while some can't, or some find them appealing, while others don't. A pair of studies appearing online on August 1 in the journal Current Biology, a Cell Press publication, now identifies the genetic differences that underpin the differences in smell sensitivity and perception in different individuals. The researchers tested nearly 200 people for their sensitivity for ten different chemical compounds that are commonly found in ...

Neuroscientists find protein linked to cognitive deficits in Angelman syndrome

2013-08-01
A team of neuroscientists has identified a protein in laboratory mice linked to impairments similar to those afflicted with Angelman syndrome (AS)—a condition associated with symptoms that include autism, intellectual disability, and motor abnormalities. The findings appear in the journal Cell Reports. "By isolating a protein that contributes to cognitive deficits in Angelman syndrome, these findings mark a step forward in not only addressing AS, but perhaps other developmental disorders as well," said Eric Klann, a professor in New York University's Center for Neural ...

Boning up: McMaster researchers find home of best stem cells for bone marrow transplants

2013-08-01
Hamilton, ON (August 1, 2013) –McMaster University researchers have revealed the location of human blood stem cells that may improve bone marrow transplants. The best stem cells are at the ends of the bone. It is hoped this discovery will lead to lowering the amount of bone marrow needed for a donation while increasing regeneration and lessening rejection in the recipient patients, says principal investigator Mick Bhatia, professor and scientific director of the McMaster Stem Cell and Cancer Research Institute. In a paper published online today by the journal Cell ...

Bacteria hold the clues to trade-offs in financial investments and evolution

2013-08-01
Scientists have found that bacteria have the potential to teach valuable investment lessons. The research, published in the journal Ecology Letters, takes advantage of the fact that bacteria, like humans, have limited resources and are constantly faced with investment decisions. Bacteria though are successful with their investments and have colonised every inch of the surface of our planet. The researchers, from the Universities of Exeter and Sydney, used mathematical models and lab-based synthetic biology, to predict bacterial investment crashes and boom-bust cycles. ...

UC San Diego researchers develop efficient model for generating human iPSCs

2013-08-01
Researchers at the University of California, San Diego School of Medicine report a simple, easily reproducible RNA-based method of generating human induced pluripotent stem cells (iPSCs) in the August 1 edition of Cell Stem Cell. Their approach has broad applicability for the successful production of iPSCs for use in human stem cell studies and eventual cell therapies. Partially funded by grants from the California Institute for Regenerative Medicine (CIRM) and the National Institutes of Health (NIH), the methods developed by the UC San Diego researchers dramatically ...

Fly study finds 2 new drivers of RNA editing

2013-08-01
PROVIDENCE, R.I. [Brown University] — RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates the process as more complex and difficult to predict than previously assumed. The study, done in living fruit flies, discovered two new mechanisms that govern editing in a key neurodevelopmental gene. RNA editing is governed not only by sequences of RNA nucleotides (the letters A, C, G, and U) and corresponding ...

Ultrasound patch heals venous ulcers in human trial

2013-08-01
In a small clinical study, researchers administered a new method for treating chronic wounds using a novel ultrasound applicator that can be worn like a band-aid. The applicator delivers low-frequency, low-intensity ultrasound directly to wounds, and was found to significantly accelerate healing in five patients with venous ulcers. Venous ulcers are caused when valves in the veins malfunction, causing blood to pool in the leg instead of returning to the heart. This pooling, called venous stasis, can cause proteins and cells in the vein to leak into the surrounding tissue ...

New designer compound treats heart failure by targeting cell nucleus

2013-08-01
Researchers from Case Western Reserve University School of Medicine and the Dana-Farber Cancer Institute have made a fundamental discovery relevant to the understanding and treatment of heart failure – a leading cause of death worldwide. The team discovered a new molecular pathway responsible for causing heart failure and showed that a first-in-class prototype drug, JQ1, blocks this pathway to protect the heart from damage. In contrast to standard therapies for heart failure, JQ1 works directly within the cell's command center, or nucleus, to prevent damaging stress responses. ...
