Blocking type 2 receptor reduces PDA cell growth with the activation of AMPK enzyme

Pancreatic cancer researchers at Thomas Jefferson University have shown, for the first time, that blocking a receptor of a key hormone in the renin-angiotensin system (RAS) reduces cancer cell growth by activating the enzyme AMPK to inhibit fatty acid synthase, the ingredients to support cell division.

New finding about cell metabolism may have implications for neurodegenerative disorders

Cells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant.

Scientists identify small molecule inhibitors of cellular uptake

Scientists from Freie Universität Berlin and the NeuroCure Cluster of Excellence led by biochemist Volker Haucke in collaboration with colleagues from Australia and the Leibniz Institute for Molecular Pharmacology in Berlin have developed small molecules that inhibit the internalization of important signaling molecules but also of pathogenic organisms such as the immunodeficiency virus and bacteria into cells.

Researchers identify new plasma membrane sculpting protein

The research group of Professor Pekka Lappalainen at the Institute of Biotechnology, University of Helsinki, has identified a previously unknown mechanism which modifies the structure of plasma membranes in intestinal epithelial cells.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Study reveals several compounds that block cancer cell invasion

Metastasis-the spread of cancer from the place where it first started to another place in the body-is the most common reason that cancer treatments fail. To metastasize, some types of cancer cells rely on invadopodia, cellular membrane projections that act like feet, helping them "walk" away from the primary tumor and invade surrounding tissues.

New transgenic mouse could predict toxicity of targeted cancer drugs

Only one in twenty cancer drugs makes its way from the laboratory to become an approved pharmaceutical product. The majority of new agents are only shown to be unsuitable in the later phases of clinical development which would explain the exorbitantly high development costs of 500 to 600 million euros per new cancer drug.

Two key genes may help prevent childhood leukemia

Researchers at The University of Western Ontario have identified genes that may be important for preventing childhood leukemia. Acute lymphoblastic leukemia (ALL) is a cancer of the blood that occurs primarily in young children.

Short telomeres may increase risk of emphysema

Telomeres, the body's own cellular clocks, may be a crucial factor underlying the development of emphysema, according to research from Johns Hopkins University.

Arabidopsis thaliana helps scientists to solve puzzles in human health

A tiny plant called Arabidopsis thaliana just helped scientists unearth new clues about the daily cycles of many organisms, including humans. This is the latest in a long line of research, much of it supported by the National Institutes of Health, that uses plants to solve puzzles in human health.

Scientists discover mechanism that enables developing cancer cells to sustain abnormal growth

Scripps Research Institute scientists have discovered a basic mechanism that can enable developing cancer cells to sustain abnormal growth. The finding is expected to lead to the targeting of this mechanism with drugs and diagnostic techniques.

Novartis Afinitor Phase III trial on tuberous sclerosis meets primary endpoint

Novartis Pharmaceuticals Corporation announced today Phase III trial results that showed more than one-third of patients taking Afinitor tablets experienced a 50% or greater reduction in the size of their subependymal giant cell astrocytomas, non-cancerous brain tumors associated with tuberous sclerosis complex.

Inhibiting heat shock transcription factor 1 prevents liver cancer in mice

Altering the body's metabolism could be an effective treatment for deadly liver cancer, researchers report.

Ways to protect children from X-ray radiation

The risk to children's health from X-ray radiation is easy to reduce without compromising diagnostic accuracy. Gerhard Alzen and Gabriele Benz-Bohm describe some ways to achieve this in the current edition of Deutsches Ärzteblatt International.

Two defective genes may cause telomere elongations in cancer cells: Study

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.

Protein c-JUN protects both tumour accelerating gene and tumour suppressor gene

The process of cell division is tightly regulated, as mistakes may lead to cancer. The so-called c-JUN protein has been fingered as causing tumours in both skin and liver. It has long been known to have a direct role in reducing the expression of a gene (p53) that leads to the death of abnormal cells and to activate transcription of a further gene (CyclinD1) that directly promotes cell division.

Redefinition of cardiac hypertrophy term needed

The European Society of Cardiology (ESC) Working Group on Myocardial Function is calling for a redefinition of the term cardiac hypertrophy which is currently used to describe changes to the morphology (structure) of the heart. Instead the position paper, published online today in the European Journal of Heart Failure, suggests that use of the general term myocardial remodelling should be preferred.

Health Canada grants market authorization for Sanofi-aventis Jevtana to treat prostate cancer

Sanofi-aventis announced today that Health Canada has granted market authorization for Jevtana injection in combination with prednisone for the treatment of patients with metastatic castration resistant prostate cancer, previously treated with a docetaxel-containing treatment regimen.

Scientists reveal complex protein mechanism that regulates genes linked with cancer

Scientists at Memorial Sloan-Kettering Cancer Center in New York and at IRB Barcelona reveal the mechanism of action of a protein that is essential for life and is associated with disease.
