| New insights on control of pituitary hormone outside of brain has implications for breast cancer Posted: 30 Sep 2012 02:37 PM PDT Recently, researchers have found that prolactin is also produced by some tissues outside the brain, however little is known about the functions of extra-pituitary prolactin or how its production is regulated in these tissues. The PI3K-Akt oncogenic signaling pathway in the mammary glands of mice rapidly induces cells in the breast itself to produce prolactin, which leads to breast tissue differentiation, and prolactin has long been thought to play a role in breast cancer.  |
| Blocking key protein could halt age-related decline in immune system, study finds Posted: 30 Sep 2012 11:21 AM PDT The older we get, the weaker our immune systems tend to become, leaving us vulnerable to infectious diseases and cancer and eroding our ability to benefit from vaccination. Now scientists have found that blocking the action of a single protein whose levels in our immune cells creep steadily upward with age can restore those cells' response to a vaccine.  |
| Scientists find missing link between players in the epigenetic code Posted: 30 Sep 2012 11:21 AM PDT New research has established the first link between the two most fundamental epigenetic tags -- histone modification and DNA methylation -- in humans.  |
| Common RNA pathway found in ALS and dementia Posted: 30 Sep 2012 11:21 AM PDT Two proteins previously found to contribute to ALS, also known as Lou Gehrig's disease, have divergent roles. But a new study shows that a common pathway links them.  |
| Gene that causes a form of deafness discovered Posted: 30 Sep 2012 11:21 AM PDT Researchers have found a new genetic mutation responsible for deafness and hearing loss associated with Usher syndrome type 1.  |
| Key mechanism for controlling the body's inflammatory response discovered Posted: 30 Sep 2012 11:21 AM PDT Researchers have discovered how a key molecule controls the body's inflammatory responses. The molecule, known as p110delta, fine-tunes inflammation to avoid excessive reactions that can damage the organism. The findings could be exploited in vaccine development and new cancer therapies.  |
| Governments failing to address 'global pandemic of untreated cancer pain' Posted: 30 Sep 2012 11:20 AM PDT Governments around the world are leaving hundreds of millions of cancer patients to suffer needlessly because of their failure to ensure adequate access to pain-relieving drugs, an unprecedented new international survey reveals.  |
| Posted: 30 Sep 2012 11:15 AM PDT Researchers have found that the spread of a dangerous bacteria that can be fatal in up to 45% of people infected in sub-Sahara Africa may have been instigated by the emergence and spread of HIV in Africa. The study also found that one of the major contributing factors for the successful spread of the disease – non-Typhoidal Salmonella (iNTS) – was the acquisition of genes that afford resistance to several front line drugs used to treat blood-borne infection such as iNTS.  |
| New weapons in the fight against cancer Posted: 30 Sep 2012 09:07 AM PDT Several new first-in-human studies for drugs targeted against a range of cancers have just been released.  |
