Scientists have gained valuable new insight into the biology of aggressive, incurable brain tumors

A research study published in the March issue of Cancer Cell uses gene expression profiling to identify molecular profiles and signaling pathways associated with tumor aggressiveness and disease progression.

Lilly launches phase III trial of Enzastaurin

One of the deadliest and rarest forms of cancer is the focus of a Phase III study initiated by Eli Lilly and Company today.

Fibulins inhibit both tumor growth and blood-vessel formation

Researchers at National Jewish Medical and Research Center report in the March issue of Cancer Research that a pair of promising proteins, known as fibulins 3 and 5, slow the growth of cancer tumors in mice by preventing blood vessels from sprouting. The proteins are promising candidates for use in cancer therapy.

Study identifies compounds that overcome a specific type of resistance to chemotherapeutic-induced apoptosis

Treatment of human cancer is often impeded when cancer cells develop resistance to drugs that are designed to induce a type of programmed cell death called apoptosis.

Nod1 found to control tumor growth in certain breast cancers

This protein was previously thought to play a role solely in the innate immune system's response to bacterial infection. In the new study, which will be published on-line by the Proceedings of the National Academy of Sciences

Dietary soy isoflavones inhibit estrogen effects in the postmenopausal breast

Research in monkeys suggests that the natural plant estrogens found in soy do not increase markers of breast cancer risk in postmenopausal women. In fact, they may provide a protective effect in some women. The research is reported in Cancer Research.

Gene discovery may prevent craniofacial birth defects

Craniofacial researchers have developed an animal model that explains how skull malformations occur and how they might be prevented.

MicroRNAs greatly influence the evolution of genes

RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated.

GRK5's role in restenosis

Researchers at Jefferson Medical College have begun to clarify the role of a protein - and potential drug target - in the process by which arteries re-clog after treatment.

Study finds AKT blocks cancer cell motility

PIn investigating the molecular mechanisms of cancer cell motility - the unique property that enables cancer to spread from its primary origin to other parts of the body - researchers have uncovered a surprising role for the AKT/PKB (protein kinase B) enzyme

Pretreating a vein graft with edifoligide prior to coronary bypass graft surgery does not lower the rate of graft failure

Coronary artery bypass graft (CABG) surgery is one of the most common surgical procedures performed in the United States, according to background information in the article. In appropriately selected patients, CABG surgery results in improved survival, relief of angina, and improved quality of life. Despite frequent use of artery grafts, vein grafts remain the most frequently used conduit.

Zyflamend shows promise in the early treatment of prostate cancer

Data from the Columbia University Department of Urology demonstrates that Zyflamend, a unique herbal extract preparation, suppresses the growth of prostate cancer cells and induces prostate cancer cells to self-destruct via a process called "apoptosis."

Researchers discover the presence of functional ion channels in human embryonic stem cells

These ion channels act like electrical wires and permit ESCs, versatile cells that possess the unique ability to become all cell types of the body, to conduct and pass along electric currents.

Study identifies molecular switch that integrates cell survival signals from multiple intracellular signaling pathways

The finding has substantial clinical significance, as mutations in these cell survival-signaling pathways are associated with many human cancers, and a better understanding of how these pathways converge to regulate the delicate balance between cell proliferation and cell death may lead to development of more effective cancer therapies.

Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.

New monoclonal antibody that targets immune system B cells shows promise for treating leukemias

In studies with mice, treatment with a new monoclonal antibody that targets immune system B cells has shown considerable promise for treating leukemias, autoimmune diseases and transplant rejection, according to immunologists at Duke University Medical Center.

New data demonstrates how CA4P has anti-tumor and anti-angiogenic activity

Anti-angiogenic agents have been successful in the clinic for blocking the growth of solid tumors. However, these agents used in combination with chemotherapy have improved the survival of patients with cancers by only several months.

Potential biomarker that could be used to predict who might develop hepatic fibrosis

Two new studies on Hepatitis C (HCV) patients who underwent liver transplants examined a potential biomarker that could be used to predict who might develop hepatic fibrosis, a formation of scar-like tissue that can lead to cirrhosis.

First true animal model for psoriasis

Scientists at the Research Institute of Molecular Pathology in Vienna have developed the first true animal model for psoriasis and have been able to address the initial steps and possible causes of the disease.

New research adds to the emerging range of functions that miRNAs perform in an organism

In an effort to understand the biological function of the microRNA mir1, Drs. Nicholas Sokol and Victor Ambros (Darmouth Medical School) have studied the expression profile, transcriptional regulation and loss-of-function phenotype of Drosophila mir-1 (Dmir-1).
