Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

Scientists eliminate metastasis in laboratory experiments

In laboratory experiments, scientists have eliminated metastasis, the spread of cancer from the original tumor to other parts of the body, in melanoma by inhibiting a protein known as melanoma differentiation associated gene-9 (mda-9)/syntenin. More than 1 million cases of skin cancer are diagnosed each year in the U.S., and melanoma is the deadliest form.

Scientists reveal timing mechanism in formation of vertebrae

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating activity of certain genes within embryonic cells. But questions remain about how precisely this timing system works.

Patients with gastric cancer have impaired TGFβig-h3 protein

Scientists at the University of Liverpool have found that the production of a protein that prevents the growth and spread of cancerous cells is impaired in patients with gastric cancer.

Study indicates that impact of early-life abuse extend well into older age

The psychological scars of childhood abuse can last well into adulthood. New research from Concordia University shows the harm can have longterm negative physical effects, as well as emotional ones.

Atpif1 gene regulates heme synthesis in red blood cell formation

Scientists at the University of Georgia, Harvard Medical School and the University of Utah have discovered a new gene that regulates heme synthesis in red blood cell formation. Heme is the deep-red, iron-containing component of hemoglobin, the protein in red blood cells responsible for transporting oxygen in the blood.

Neuroticism can be good for health under certain circumstances

Under certain circumstances neuroticism can be good for your health, according to a University of Rochester Medical Center study showing that some self-described neurotics also tended to have the lowest levels of Interleukin 6 (IL-6), a biomarker for inflammation and chronic disease.

Scientists discover how external signals regulate vascular remodelling at cell level

Blood vessels are extremely dynamic: depending on the external conditions, they can adapt their permeability for nutrients, their contractility, and even their shape. Unlike cardiac muscle cells, for example, the smooth muscle cells in blood vessels demonstrate a high degree of plasticity, so they can specialise or multiply as required, even repairing damage to the vessel wall.

Patients with focal segmental glomerulosclerosis tend to have high suPAR levels

Patients with a disease that is a leading cause of kidney failure tend to have high levels of a particular factor circulating in their blood, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

UIC researchers develop transgenic Alzheimer's mouse with apoE4 gene

Researchers at the University of Illinois at Chicago College of Medicine have developed a transgenic mouse that carries a human gene known to increase risk of Alzheimer's 15-fold. This new mouse mimics the genetics of the human disease more closely than any of the dozen existing mouse models and may prove more useful in the development of candidate drugs to prevent or treat the disease.

Pevion launches Defensomes platform for broad spectrum immune enhancement

Pevion Biotech AG today announced the launch of a new program called Defensomes, a platform for broad spectrum immune enhancement via mechanisms of innate immunity. The proprietary technology is derived from a vaccine platform with a solid safety track record comprising more than 80 million doses applied to humans to date. Defensomes offer opportunities for a wide range of prophylactic and therapeutic indications, where boosting of the body's own natural defense is beneficial.
