Hope For Patients With Macular Degeneration From Manmade Protein

...nts target VEGF outside cells. 'It is important to bind it within cells because certain cells, such as cancer and blood vessel cells, have the capability to produce their own VEGF and their own receptors,' Dr. Ambati says. 'Imagine trying to block from the outside a factory that has everything it needs in...

Women in the throes of depression portray differences in brain chemistry

...brain cells that brain chemicals called mu-opioids bind to. Mu-opioids, sometimes also called endorphins, reduce or block the spread of messages related to pain, stress and emotional distress between the body and the brain. They have been called the body's "natural painkillers." The drug is modified to al...

Novel methods to view how a drug attaches to a cell

...porphyrin molecule and, after allowing the drug to bind to a cell, using light to grow a nanometer-sized particle. The nanoparticles can then be imaged with electron microscopy to reveal the location of the drug receptor molecules on the cell," Shelnutt says. "This type of nanotagging technique might be u...

International Collaboration Takes Aim at Rabies

... searching for antibodies that would recognize and bind to the rabies virus coat or glycoprotein. The team isolated a series of those antibodies, and tested them against live rabies virus strains in culture. That research found one MAB in particular, now called HuMAB 17 C7, which worked dramatically and b...

Regulatory Mechanism for Tumor Suppressor Protein Identified

... p53 protein were present at all times and able to bind to DNA, cells would be in big trouble," Berger exp...ecific site, with the result being that p53 cannot bind to DNA and, therefore, cannot act. "The ability to bind to DNA is critical for p53's function," say...

Private health clinics to be regulated

...ervices. //This will mean that new guidelines will bind private health clinics to discharge both insured as well as uninsured healthcare services. D'Entremont says private facilities will be able to provide only licensed uninsured services. Besides the legislation will also include a contract with the ...

Low Doses Of Arsenic Have Broad Impact On Hormone Activity – Says A Researc

... receptor to move to the nucleus of the cell or to bind to DNA to initiate gene expression. Yet, somehow arsenic still strongly affects the ability of these hormone-activated receptors to regulate gene expression. There's still a lot more to learn." The study also looked into the effects of different l...

Aggressive Stem Cells Might Improve Transplant Outcome

...irst demonstrated that class II and III antibodies bind to different populations of CD34+ cells by adding both of these antibodies to pieces of human thymus glands. The pieces of thymus glands used in the study had been removed from children during operations unconnected to this research and would otherwi...

Survival of Mice With Human Breast Cancer Extended by Monoclonal Antibodies

... only would drugs attached to the antibody JAA-F11 bind to the tumor cell surface to direct their cytotoxic effect, but the binding of the antibody itself would block the cell from metastasizing." The antibody was tested using in vitro models of tumor cell growth, in assays to determine its ability to d...

Pros and Cons of Therapy for Lead Exposure

...hat were exposed to lead. Chelating drugs, which bind to lead and other metals in the blood, are increasingly being used for the treatment of autism in children. "Although these drugs are widely used to treat lead-exposed children, there is remarkably little research on whether or not they improve cog...

'Clumping' Protein Linked to Return of Ovarian Cancer

...ped off NAC-1 proteins disrupting their ability to bind with each other. This action can prevent tumor formation and kill cancer cells in experimental mice. Shih says that in the future, drugs that mimic N130 can be used to treat cancer. Source-Newswise SRM...

Anti Allergy Drugs Reduce Tumor Growth

.... However, Dr. Logsdon has found that cromolyn can bind a specific protein produced by cancer cells and block that protein's ability to interact with a receptor that stimulates cancer cell growth, survival, and spreading. The relationship between how the drug controls allergies and its anti-tumor effect i...

Molecular ‘On/Off Switch’ Controls Immune Defenses Against Viruss

...he key site that regulates the ability of RIG-I to bind to its signaling partners, including LGP2, acting as a switch for controlling immune response, Dr. Gale said. “Hepatitis C and others viruses hijack this signaling pathway to stop immune defenses,” he said. His research team and others are workin...

A New Strategy to Control Breast Cancer

... that regulate the production of the ligands which bind and activate EGFR,” Kenny said. “We reasoned that this binding and activation is essential for EGFR activation and that finding a way to block this interaction might prove to be an important additional approach to explore for inhibition of this path...

New Method May Treat Brain Injuries

...me called GOT that is normally present in blood to bind glutamate chemically and inactivate it, effectively lowering levels in the blood and kicking transporter activity into high gear. In their experiments, Teichberg and his colleagues used this method to scavenge blood glutamate in rats with simulated t...
