Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...ered orally and appear in often-difficult-to reach organs such as the prostate. "This is what suggested to us that Enigmols should be tested against other cancer types," Merrill explained. Subsequently, the researchers found that Enigmols suppress the growth of human prostate tumors implanted in mice, whic...

Could microbes solve Russia's chemical weapons conundrum?

...vere damage to the respiratory system and internal organs if ingested or inhaled. It accounts for around 2 percent of Russia's CWA stockpile. Around 60 percent of the mustard RM consists of derivatives of a toxic compound called 1,4-perhydrothiazine (PHT). Ermakova's research team grew P putida in culture...

Molecular thermometers on skin cells detect heat and camphor

...ystem of sensory neurons that connect the brain to organs like the eye, ear, nose, and mouth. In recent years, biologists and neuroscientists have been trying to discover the basic molecules and mechanisms that underlie this complicated communication system that is our senses, and one group of researchers ...

Future diabetes drugs may target new protein interaction

...od shortages; the brain and certain other critical organs rely on sugar -- specifically glucose -- for the energy to function. In people with diabetes, however, the liver doesn't sense the incoming calories, and it keeps making glucose when it shouldn't. The researchers discovered that, in fasting mice, th...

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

...g field of organogenesis, which focuses on growing organs from stem cells and other embryonic cell clusters known as organ primordia. Unlike embryonic stem cells, which can become virtually any cell type, primordia are locked into becoming a particular cell type or one of a particular set of cell types that...

Active Vaccine Prevents Mice From Developing Prion Disease

...l be destroyed in the gut and will not reach other organs in the body." Because the research was conducted in normal mice, the NYU researchers say it will be easier to apply in animals in the wild, which are at risk for developing prion disease. Prion disease is contracted when an animal eats the body part...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

... Two to three days later they harvested cells from organs where the bacteria tend to cluster. They used a dye to stain those cells green. When Y. pestis attacks a cell it uses the type-III pathway -- a needle-like projection -- to inject various toxins into the cell, killing it. The researchers endowed the...

Mechanism for the captation of nutrients in plants- unknown to date

...ibuted around the plant), the cells of the reserve organs - such as roots, tubers, seeds or fruits - "swallow up" nutrients in order to metabolise and store them. These "swallowed-up" substances are incorporated into micro-vesicles that end up pouring their contents into an internal compartment of a vegetab...

Arthritis: What Wnt wrong?

...cause its disruption can lead to cancer in various organs such as colon, lung, and breast. However, mounting evidence also points to its involvement in arthritic joint disease. Comprehensive analysis of the entire Wnt gene family in the progression of arthritis has been lacking until now. Researchers at Sh...

In contrast, lung cancer detected at an early stage boasts a 50 percent survival rate over a five-year period. "There are many similarities between stem cells and cancer," said first author Carla B...
