Novel Enzyme Inhibitor Paves Way For New Cancer Drug
Combining natural organic atoms with metal complexes, scientists at The Wistar Institute have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development.Based on studies in human melanoma cells, the research paves the way for developing new ways to treat cancer by dampening the overactive enzyme activity that leads to uncontrolled tumor growth.
Targeted Therapy Plus Chemotherapy May Pack 1-2 Punch Against Melanoma
By targeting and disabling a protein frequently found in melanoma tumors, doctors may be able to make the cancer more vulnerable to chemotherapy, according to a new study by researchers in the Duke Comprehensive Cancer Center."We tested a compound that can weaken the tumor by targeting a protein expressed on the surface of a melanoma cell.
The Conversion Of White-To-Brown Fat Cells As A Therapeutic Treatment For Obesity
In the May 15th issue of G&D, Dr. Bruce Spiegelman (Dana Farber Cancer Institute) and colleagues elucidate the molecular pathway that induces cells to become energy-burning brown fat cells as opposed to energy-storing white fat cells.
Lung Damage In Emphysema Halted By Common Acne Drug
An antibiotic commonly used to treat acne can prevent tissue damage caused by lung diseases such as emphysema, researchers have found.A team of researchers from the Universities of Leeds and California, San Diego, studying a protein called VEGF have found that doxycyline - used to treat common ailments such as acne, sinusitis and urinary tract infections - also boosts the body's ability to protect against damage to the lungs.
Australian Researchers Sheds New Light On Heroin Addiction
Researchers from the Howard Florey Institute in Melbourne have identified a factor that may contribute towards the development of heroin addiction by manipulating the adenosine A2A receptor, which plays a major role in the brain's 'reward pathway'.Using mice specifically bred without the adenosine A2A receptor, Prof Andrew Lawrence and his team showed that these mice had a reduced desire to self-administer morphine; heroin is converted to morphine in the body.
