Angiogenesis News and Research

RSS

Angiogenesis is blood vessel formation. Tumor angiogenesis is the growth of new blood vessels that tumors need to grow. This is caused by the release of chemicals by the tumor.

Microvesicles released from glioblastoma cells carry information that may guide treatment

Microvesicles - tiny membrane-covered sacs - released from glioblastoma cells contain molecules that may provide data that can guide treatment of the deadly brain tumor.

Chaotic vasculature hinders tumor growth

Dense networks of blood vessels thought to spur cancer's growth could actually hinder rather than promote tumor progression, according to a new study at the University of California, San Diego.

Further evidence that angiogenesis drugs can be much more effective when combined with chemotherapy

Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein.

Genentech submits application to FDA for Avastin in the most aggressive form of brain cancer

Genentech has announced that the company submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for Avastin (bevacizumab) as a therapy for people with previously treated glioblastoma. If accepted by the FDA, the application would be considered for an accelerated approval that allows provisional approval of medicines for cancer or other life-threatening diseases based on preliminary evidence suggesting clinical benefit.

Healing process found to backfire in idiopathic pulmonary fibrosis patients

A mechanism in the body which typically helps a person heal from an injury, may actually be causing patients with idiopathic pulmonary fibrosis (IPF) to get worse, researchers at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health (NIH), and their collaborators have found.

Targeted nanoparticles map tumor blood supply in 3-D, assess therapy

One of the defining characteristics of solid tumors is the development of a network of new blood vessels to nourish the rapidly reproducing malignant cells. Now, using a nanoparticle targeted to those new blood vessels, a joint academic-industrial research team, led by investigators from the Siteman Center of Cancer Nanotechnology Excellence, has developed a way to construct a three-dimensional (3-D) map of tumor-induced angiogenesis and monitor the effects of drug therapies on those new blood vessels.

Benefits of combined treatments against cancer

In cancer therapy, the best results are often achieved by combining treatments such as chemotherapy, radiotherapy and surgery. This multidisciplinary approach is the focus of special symposia at the meetings of the European Society for Medical Oncology (ESMO) and the European Society for Therapeutic Radiology (ESTRO) taking place in Sweden this month.

Investigational drug shows promise in ovarian cancer

An investigational drug that combats ovarian cancer by inhibiting the formation of new blood vessels has shown promise in a phase II trial, according to a presentation at the 33rd Congress of the European Society for Medical Oncology (ESMO) in Stockholm.

FDA grants IND for Davanat to treat breast cancer patient

Pro-Pharmaceuticals, Inc. has announced that the U.S. Food and Drug Administration (FDA) has granted an Investigational New Drug (IND) application for use of Davanat in combination with 5-FU to treat a breast cancer patient at the Brown Cancer Center in Louisville, Kentucky. Davanat also is being administered in Phase II clinical trials for first-line treatment of colorectal and biliary cancer patients.

Normalizing tumor vessels to improve chemotherapy drug delivery

Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at Children's Hospital Boston.

Cheap drug combo stops breast cancer in its tracks

A drug 'combo' of chemotherapy and a treatment for brittle bones has a dramatic effect on breast cancer according to researchers in the UK.

Scientists identify microRNA that controls blood vessel development - therapeutic target for a number of diseases

Scientists from the Gladstone Institute of Cardiovascular Disease (GICD) and UCSF have identified a key regulatory factor that controls development of the human vascular system, the extensive network of arteries, veins, and capillaries that allow blood to reach all tissues and organs.

New therapies revealed for diabetes-induced microvascular disease

New findings from Bristol scientists could lead to future treatments to prevent lower limb amputations in diabetes - which currently affect 100 people a week in the UK (source Diabetes UK). The research from the University of Bristol is published online in Circulation Research and was funded by the British Heart Foundation (BHF) and the European Vascular Genomic Network of Excellence (EVGN).

Nanomaterials key to new strategies for blocking metastasis

A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue, according to a collaborative team of researchers at the Center of Nanotechnology for Treatment, Understanding, and Monitoring of Cancer at the University of California, San Diego. In designing this system, the investigators, led by David Cheresh, Ph.D., have identified what may become a generic method for using nanotechnology to target metastasis.

Minocycline may find new life as a stroke treatment

An old intravenous antibiotic may have new life as a stroke treatment, researchers say. Minocycline appears to reduce stroke damage in multiple ways - inhibiting white blood cells and enzymes that, at least acutely, can destroy brain tissue and blood vessels, respectively, says Dr. David Hess, chair of the Department of Neurology in the Medical College of Georgia School of Medicine.

Discovery of new gene that causes cancer

Researchers at the OU Cancer Institute have identified a new gene that causes cancer. The ground-breaking research appears in Nature's cancer journal Oncogene.

Discovery of new cell targets for preventing growth of breast and other tumors

Researchers at the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill have discovered new targets for cancer treatment aimed at blocking a key step in tumor progression.

A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?

It is widely believed that tumor angiogenesis and cancer growth critically depend on circulating endothelial precursor cells, mobilized from the bone marrow. The recent study from researchers at the University of Helsinki, Finland, and Stanford University, US, now suggests that a stem cell type supposed to be crucial for blood vessel formation and cancer growth does not actually exist.
