Keryx KRX-0401 data in colorectal cancer, multiple myeloma presented at AACR meeting

Keryx Biopharmaceuticals, Inc. today announced that two posters on KRX-0401 were presented at the 102nd annual meeting of the American Association for Cancer Research currently ongoing at the Orange County Convention Center in Orlando, Florida. Perifosine, the Company's novel, potentially first-in-class, oral anti-cancer agent that inhibits Akt activation in the phosphoinositide 3-kinase pathway, is currently in Phase 3 clinical trials for refractory advanced colorectal cancer and multiple myeloma.

Lack or loss of SIRT3 protein induces proliferation of breast cancer cells

Research published in the Cancer Cell journal in March was a significant step in knowing the causes of cancer better, especially breast cancer, revealing that the lack or loss of a protein in the cells known as SIRT3, induces the proliferation of this disease and thereby, this protein can be an may be a therapeutic target in the development of effective therapies for cancer. The research was led by Dra. Marcia Haigis of the Harvard Medical School, with the participation of Dr. Arkaitz Carracedo, from the Proteomics Laboratory at CIC bioGUNE.

Researchers to develop future body sensor network

Modern man is surrounded by a multitude of sensors. Today's sensors are simple and made for specific purposes, like measuring temperature, balance, build-up of smoke, or tyre pressure. The common trait of the sensors is that they are all embedded in a closed system.

Study suggests causal link between HSV1 and Alzheimer's disease

Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells.

New ‘nanotech’ weapon against drug-resistant superbugs

Scientists at the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research – Almaden have developed the first biodegradable polymer nanoparticles to combat drug-resistant superbugs, such as Methicillin-Resistant Staphylococcus aureus (MRSA). These nanoparticles can selectively kill the bacteria without destroying healthy red blood cells, and being biodegradable, have great potential to treat infectious diseases in the body. This was reported today in the leading scientific journal, Nature Chemistry [(2011) DOI: 10.1038/nchem.1012].

Potential HIV vaccine component undergoes dramatic protein rearrangement

An international study headed by a UC Davis scientist describes how a component of a potential HIV vaccine opens like a flower, undergoing one of the most dramatic protein rearrangements yet observed in nature. The finding could reveal new targets for vaccines to prevent HIV infection and AIDS. A paper describing the work was published online this week in the journal Proceedings of the National Academy of Sciences.

Study: Pseudokinases can play a crucial role in pathogen-based disease

Researchers from the University of Pittsburgh and Stanford University discovered that a supposedly inactive protein actually plays a crucial role in the ability of one the world's most prolific pathogens to cause disease, findings that suggest the possible role of similarly errant proteins in other diseases.

New signaling pathway discovery sheds light on chronic dermatitis

A new signaling pathway, which is important for the regulation of the immune response and inflammation, was discovered by an international team of scientists led by prof Ivan Dikic from the Goethe University, Frankfurt, Germany.

Micro-RNAs appear to play a key role in new mechanism underlying obesity

Max Planck researchers have discovered a new mechanism that leads to the development of type 2 diabetes in obesity. Body weight influences the risk of developing diabetes: between 80 and 90 percent of patients with type 2 diabetes are overweight or obese.

Mucus may play a key role in penetration of hydrophobic substances into cells

Are our bodies vulnerable to some pollutants whose lack of solubility in water, or "hydrophobicity," has always been thought to protect us from them? New Tel Aviv University research has discovered that this is indeed the case.

Researchers identify new mechanism underlying MS

Multiple sclerosis is a disabling autoimmune disease in which nerve fibers are attacked by the patient's own immune system. Researchers at Ludwig-Maximilians-Universitaet in Munich have identified a new mechanism that contributes to nerve fiber damage - and shown that this damage can be reversed.

Imaging with voltage-sensitive dye captures real-time brain dynamics

The dye incorporates in the brain cells' membrane and changes fluorescence whenever these receive or send electrical signals. Hence, high resolution camera systems allow to simultaneously capture activities of millions of nerve cells across several square millimeters across the brain.

New study provides insights into epiboly mechanisms linked with wound healing, cancer

Avian embryos could join the list of model organisms used to study a specific type of cell migration called epiboly, thanks to the results of a study published this month in the journal Developmental Dynamics.

Researchers create hiPS-RPE cells to treat age-related macular degeneration

The notion of transplanting adult stem cells to treat or even cure age-related macular degeneration has taken a significant step toward becoming a reality. In a study published today in Stem Cells, Georgetown University Medical Center researchers have demonstrated, for the first time, the ability to create retinal cells derived from human-induced pluripotent stem cells that mimic the eye cells that die and cause loss of sight.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Biologists decipher molecular code regulating availability of brain channel linked to neuronal excitability

A key question in protein biochemistry is how proteins recognize "correct" interaction partners in a sea of cellular factors. Nowhere is that more critical to know than in the brain, where interactions governing channel protein activity can alter an organism's behavior.

New synchrotron-based imaging technique offers more detailed chemical images

With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM), led a team of researchers from UWM, the University of Illinois at Urbana-Champaign and University of Illinois at Chicago (UIC) to demonstrate these new capabilities.

Researchers discover 'broad spectrum' cancer suppressor gene

Portuguese researchers have discovered a "broad spectrum" cancer suppressor gene - called LRP1B - which acts by removing proteins crucial for cancer development from the tumour environment. The fact that LRP1B does not act on the tumour itself (in this study thyroid tumours) but, instead, on molecules which are known to be important to many different cancers is what makes it so interesting.
