Action of dopamine may be particularly important for understanding psychiatric conditions

Duke University Medical Center researchers have discovered a new mechanism by which chronically high levels of the neurotransmitter dopamine exert their effects on the brain.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Curcumin has potent anticancer powers

Curcumin, a spice commonly used in curries and other south Asian cooking, blocks a key biological pathway needed for development of melanoma and other cancers, say researchers from the University of Texas M. D. Anderson Cancer Center.

AAV2 has great potential to be developed as an anti-cancer agent

Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers.

Lorus Therapeutics receives patent allowance to protect novel anticancer drug

Lorus Therapeutics today announced that its wholly owned subsidiary, GeneSense Technologies Inc. (GeneSense), has received notice from the European Patent Office of its intention to grant GeneSense's application for a patent of its novel antisense drug, GTI-2501.

Test accurately predicts aggressiveness of breast cancer

A test that measures how quickly cells are dividing is an accurate way for doctors to predict the aggressiveness of breast cancer tumors, even among women with very early stages of the disease, researchers told the 2nd ESMO Scientific & Educational Conference (ESEC) in Budapest, Hungary.

New drug combination prevents breast cancer growth pre-surgery

A new type of drug originally developed for lung cancer can reduce the size of breast cancer tumours when taken in combination with other drugs.

Gefitinib (Iressa) could reduce the size of breast cancer tumours

Giving women with early breast cancer a drug called gefitinib (Iressa) before surgery could reduce the size of their tumours, suggests a randomised trial published online today by The Lancet Oncology.

Drugs that block the enzyme Odc prevent the onset of cancers

The drug DFMO prevents cancer in laboratory models of lymphoma but fails to kill existing cancerous cells that have lost the ability to self-destruct, according to investigators at St. Jude Children's Research Hospital.

Researchers determine structure of binding site of colon-cancer drug Erbitux and its protein target

Researchers at the University of Pennsylvania School of Medicine have determined the precise molecular details of how Erbitux, a recently approved colorectal cancer drug, binds to its target on cancer cells. Knowing this chemical configuration will lead to better drug design for this family of cancer medications.

Researchers show role of Epstein-Barr virus in cancer

Researchers at the University of Toronto have mapped the molecular details that show how a viral protein coded in the Epstein-Barr virus immortalizes cells and causes them to continuously grow, thereby predisposing people to certain types of cancer.

Statins, other cholesterol-depleting agents, may disrupt hypertension from developing

Cholesterol-lowering agents, such as the widely-prescribed statin drugs, and cholesterol-blocking agents may prove to be “novel therapeutic agents to modify cellular calcium that contributes to the development of pulmonary hypertension,” according Hemal H. Patel who lead a multidisciplinary team of researchers at the University of California, San Diego (UCSD).

Three different leukemias are all caused by mutations that alter a specific enzyme controlling blood cell proliferation

Identifying the genetic malfunction that causes these disorders raises the hope that researchers may be able to devise a targeted therapy, just as they have done for chronic myelogenous leukemia (CML), which is presently treated with Gleevec. The three leukemias that share a common genetic cause are polycythemia vera (PV), essential thrombocythemia (ET) and myeloid metaplasia with myelofibrosis (MMM).

Strawberries destroy cancer cells

Researchers specializing in the health benefits of plant compounds have shown that quercetin, a phytonutrient found in abundance in strawberries and other fruits, can induce programmed self-destruction of human cancer cells.

Gene named ATBF1 may contribute to the development of prostate cancer

A gene named ATBF1 may contribute to the development of prostate cancer through acquired mutations and/or loss of expression, according to research at Emory University School of Medicine and its Winship Cancer Institute.

Fasting every other day, while cutting few calories, may reduce cancer risk

New research at the University of California, Berkeley, raises such a possibility. It shows that healthy mice given only 5 percent fewer calories than mice allowed to eat freely experienced a significant reduction in cell proliferation in several tissues, considered an indicator for cancer risk.

New cancer drug looks promising

Dr. E. Premkumar Reddy from Temple University School of Medicine and colleagues, in a study examining the effects of Plk1 inhibitor ON01910 on tumor growth in several animal models have found that a small molecule inhibitor of polo-like kinase1 (Plk1) could lead to a new avenue for targeted cancer therapy.

Research reveals a novel key player in the initiation of colon cancer

Gastric and colorectal cancers account for more than 1 million deaths worldwide every year and several research groups have been working to identify the molecular events that result in the initiation and progression of these tumors.

Significant advance toward understanding lifelong process of blood cell formation

A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene known to be required for blood cell formation. Information gained from this research will be useful for future studies aimed at directing stem cell differentiation in a variety of potential therapeutic contexts.

Tobacco smoke triggers the production of COX-2

Tobacco smoke triggers the production of COX-2, a cellular protein linked to the development and progression of cancer, according to research published in the January 15 issue of the journal Cancer Research.
