Chemical Signaling Helps Regulate Sensory Map Formation In The Brain

.... Here, the researchers show that a gradient of a molecule known as Wnt3 counterbalances another force provided by the EphrinB1-EphB signaling system. The balance between these two signaling systems, they show, is necessary to establish the carefully controlled pattern of nerve connections required to convey...

Calcium Receptor Vital For Stem Cell Migration to Bone Marrow

A new discovery of a dictator molecule that governs the migration of blood stem cells to the bone marrow, resulting in subsequent production of blood cell components and immune stem cells could // hold the key to the development of more effective stem cell therapy for malignant and non-ma...

Self-defense Mechanism of food borne bugs found

...oduces a protein called NorR which contains a iron molecule which binds to the nitric oxide produced by the host and protects the bacterium against host defense. The researchers feel that by finding a mechanism by which the activation of NorR is prevented, it is possible to find new therapeutics and drugs ...

Understanding the RNA binding protein and its functions inside the cell

...nique which will help us to understand the way RNA molecule interacts with the other molecules present in the ...y RNA interactions in live cells. A multi-talented molecule was made by the Penn researchers in association with ?lo Langel from Stockholm University. This mo...

So now here might come a memory molecule!!!

...recent study researchers might be able to isolates molecule that would be helpful and responsible for learning and memory.// The revolutionary study has been done independently by teams from Harvard Medical School and Children's Hospital Boston and they have identified a master protein that shows how neurons...

TNF Helps in the Understanding of the Immune System and Development of Drugs against Various Ills

...jor role played by the tumor necrosis factor (TNF) molecule in the activation of the immune system to combat i...to join in the fight. The message is sent by a TNF molecule attaching onto the surface of a neighboring cell and accesses a biological information highway calle...

Gold Therapy- A Potential Treatment For Autoimmune Diseases

... possessed the remarkable property of Class II MHC molecule inactivation. The results of this study can be directly applied to clinical medicine once the mechanism of gold action is unraveled and the effectiveness of this therapy proved. Gold has been used in the treatment of autoimmune disorders following ...

Non-Coding RNA Vital For Gene Activation And Protein Expression

...tivators, in this case Ash1 bind to the target DNA molecule to facilitate the activation of certain genes that play a crucial role in determination of cell function. The mechanism of recognition of a specific DNA sequence (target gene) by the epigenetic factors followed by binding and expression has remained ...

Concerta, Drug Used in ADHD Treatment Less Likely To Result In Abuse

...HD act by inhibition of dopamine transporter. This molecule accounts for increased levels of the neurotransmitter in the brain. ADHD patients lose control over movement, behaviour and attention, as their brains do not regulate the dopamine levels effectively. Such stimulant drugs though provide control of AD...

Designer Strawberries

...od takes advantage of Agrobacterium's circular DNA molecule (T-DNA) to deliver DNA to the plant. By helping researchers establish the function of large numbers of strawberry genes, this method could, in the long term, be extremely useful in enhancing the nutritional value of these plants as well as the amount...

Anticancer Properties of Vitamin D Revealed

...itamin is made in the skin when a cholesterol-like molecule interacts with ultraviolet light. It has long been known that a lack of vitamin D can lead to the bone deformities associated with rickets, and the vitamin helps maintain calcium and phosphorous levels in bone and blood. Too much vitamin D, however, ...

Scientists Identify Key Element For Future Cancer Vaccine

... researchers were able to screen a a short peptide molecule that the T cell detects. The reserachers say that this could prove useful in vaccinations for preventing the spread of tumors to different tissues, a process that is called metastasis. Such tumors include melanoma, colon cancer, lymphoma, and fibrosa...

Heart Disease Can Be Avoided By Tackling The Cholesterol Early

...dest reduction in low-density lipoprotein (LDL), a molecule that transports cholesterol in the blood over a lifetime, could slash one's risk of heart disease, the number-one killer in the US and many other Western countries. LDL is strongly associated with heart disease. Doctors already know that reducing i...

Two New Drugs For Breast Cancer Show Promise

...searchers is lapatinib, which is given orally. The molecule is a subset of Epidermal Growth Factor Receptors (EGFR). Preliminary results suggest that the drug could kill cancer cells that are not killed by other breast cancer drugs. Dr F. Cardoso from the Jules Bordet Institute, Brussels, who is involved in t...

Botox Treatment Now With A Lesser Dose And Increased Safety

...sociates says that they have developed a synthetic molecule that binds to the toxin and increases its normal function, The discovery of small molecule activators may ultimately provide a valuable method for minimizing dosage, reducing resistance, and ...
