Only a small percentage of carcinoid tumors secrete the chemicals that cause carcinoid syndrome.
Bees also secrete an enzyme that adds a small amount of hydrogen peroxide.
The system is an attractive arrangement for customers who need to secrete large quantities of cash out of China.
In the process they also secrete calcium carbonate that becomes the basis for an external skeleton on which they sit.
Before now bees were thought to secrete 2-heptanone as an alarm pheromone to tell other colony members about a potential threat.
As bees make honey they secrete glucoseoxidase, an enzyme that releases the bleach hydrogen peroxide when it comes into contact with wound liquids.
The genes secrete recombinant protein, which the researchers purify and pass off to two partners in Brazil FIOCRUZ and Instituto Butantan which manufacture the vaccines.
The body's response to prolonged periods of stress is to secrete increasing amounts of cortisol, a hormone that marshals resources to cope with crises.
The most important of these is to get the algae to secrete their products into the culture medium in which they are being raised.
Richards, 38, had claimed he had gone to the shop to buy brown tape for bagging up drugs which he would secrete on his person.
Geological history shows that anthozoans secrete their calcium carbonate skeletons more slowly during periods when there is a lot of carbon dioxide in the atmosphere.
One idea, put forth by Soon-Shiong himself, was that when cancer cells metastasize they secrete a protein called SPARC, which also leads them to absorb Abraxane.
FORBES: Celgene's Abraxane Extends Life By 1.8 Months In Advanced Pancreatic Cancer
However, closer examination revealed differences between men and women in two key components of the immune system - T-cells, which protect the body from infection, and B-cells, which secrete antibodies.
For instance, carcinoid lung tumors that secrete chemicals into the blood do so farther upstream from the liver not directly into the liver, where the chemicals are processed and eliminated.
Rather than grow and harvest biomass, such as wood chips or algae, and then process that into fuel, Joule has engineered microorganisms to secrete fuel and chemicals, including ethanol and diesel.
These hormones include cortisol (which is related to stress), estradiol (the main female sex hormone) and prolactin (which, as its name suggests, triggers her breast tissue to develop the ability to secrete milk).
Nerves from a part of the rat brain known as the basal forebrain are thought to secrete the chemical acetylcholine into the brain's main vision center, also called the primary visual cortex, reinforcing connections that were recently active.
MSN: Goggle-wearing rats show link between learning, rewards
Dr Baker's results therefore support the previously untested hypothesis that not only do cells which are at the Hayflick limit stop working well themselves, they also have malign effects (presumably through chemicals they secrete) on their otherwise healthy neighbours.
ECONOMIST: A way to counteract part of the process of growing old
Several companies are already seeking to take advantage of the new field, called synthetic biology, which combines chemistry, computer science, molecular biology, genetics and cell biology to breed industrial life forms that can secrete fuels, vaccines or other commercial products.
Although it is understandably tight-lipped about the exact mechanism behind its success, one probably enlists the help of cells called keratinocytes, which interact naturally with the dermal papilla cells of the hair follicle and secrete a chemical factor that supports their growth.
Alternatively, chemicals they secrete may stimulate changes in cells already present in the heart a suggestion encouraged by the work of Paul Riley at University College, London, who has (in mice) stimulated stem cells which were already present to turn into cardiac muscle by adding a protein called thymosin beta 4 that throws a crucial genetic switch in stem cells, and thus activates them.
