Insights into causes of Idiopathic Pulmonary Fibrosis

Tracking individual cells within the lung as they move around and multiply has given Duke University researchers new insights into the causes of Idiopathic Pulmonary Fibrosis (IPF) a disease which can only be treated now by lung transplantation.

Pericyte cells become key players in shaping blood flow in the brain

Cells in the brain called pericytes that have not been high on the list of targets for treating diseases like Alzheimer's may play a more crucial role in the development of neurodegenerative diseases than has been realized.

Pericytes regulate blood-brain barrier

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

Pericytes may use mechanical forces to initiate angiogenesis: Researchers

Pericytes, the contractile cells surrounding capillaries, may use mechanical forces to initiate angiogenesis, the "sprouting" of new blood vessels, according to researchers at Tufts University School of Medicine and the Massachusetts Institute of Technology.

First patient enrolled in Phase II clinical trial of E10030 for treatment of wet age-related AMD

Ophthotech Corp., a privately held biopharmaceutical company focused on developing ophthalmic therapies for back-of-the-eye diseases, today announced that the first patient has been enrolled in its Phase II randomized, controlled clinical trial of E10030, an anti-PDGF aptamer, in combination with Lucentis® for the treatment of wet age-related macular degeneration (AMD).

Reference platform for diabetic retinopathy and other vascular complications

The volume addresses a variety of current scientific discussions about mechanisms of damage such as growth factors and the VEGF/PEDF balance in the diabetic eye, the ocular renin-angiotensin system, and leukocyte interactions with the microvasculature among others.

Targeting normal cells that surround cancer cells increases the effectiveness of traditional anti-cancer treatments

Targeting the normal cells that surround cancer cells within and around a tumor is a strategy that could greatly increase the effectiveness of traditional anti-cancer treatments, say researchers at The Wistar Institute.

Combination of inhibitor and antioxidants may help prevent diabetes complications

In diabetes patients, high blood glucose levels can end up killing certain cells in the eyes and kidneys, which is why diabetes is the leading cause of adult blindness and of kidney failure. Years ago, scientists identified one main route for this destruction—high glucose produces oxidative stress through the NF-kB molecular pathway—but success has been elusive for drugs targeting that pathway.

Reprogrammable cell type depends on a single gene to keep its identity

Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it.

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.

Rapamycin and Gleevec reverses effects of portal hypertension in rats

A combined treatment with rapamycin and Gleevec might reverse the effects of portal hypertension in patients with chronic liver disease, according to the results of a new study on rats.

Researchers culture blood-forming stem cells from human fat tissue

Researchers at the University of Pittsburgh School of Medicine have successfully isolated and cultured human hematopoietic stem cells from fat, or adipose, tissue, suggesting that they have found another important source of cells for reconstituting the bone marrow of patients undergoing intensive radiation therapy for blood cancers.

Improvement of cancer-targeting therapy, using nanocarriers for intractable solid tumors by inhibition of TGF-beta signaling

Administering a small amount of a potent but potentially toxic anticancer agent along with nanoparticles loaded with a second anticancer agent produced a dramatic inhibition of tumor growth in normally intractable cancers. These findings suggest a new approach to treating malignancies such as pancreatic cancer and diffuse gastric cancer.

Arf gene prevents excessive growth of blood vessels in the developing eye

A gene better known for its role in preventing cancer also plays a key role in the developing embryo, where the gene prevents excessive growth of blood vessels, according to investigators at St. Jude Children's Research Hospital.

Critical lock and key mechanism found for the assembly of tumor blood vessels

A critical lock and key mechanism that allows the final step in the completion of new blood vessel formation has been identified by a University of California, San Diego (UCSD) School of Medicine team in research that promises to lead to a new way to halt tumor growth by cutting off the tumor blood supply.

Timing of radiation and antiangiogenic therapy impacts treatment effectiveness

Agents designed to attack blood vessels that feed a growing tumor are effective against tumor growth in laboratory experiments. However, results of early clinical trials with these inhibitors have not yet exhibited the same success observed in animal models.

Potential new strategy for blocking tumor growth

Targeting a master molecule that helps cancer cells survive when blood oxygen levels are low may offer a potentially powerful strategy for blocking tumor growth, say researchers at The University of Texas M. D. Anderson Cancer Center.
