(Ivanhoe Newswire) "“ A key for early diagnosis of cancer and personalized medicine is the order of genetic aberrations - deviations or irregularity - in individual cancers. Now, scientists have begun to reveal the order of mutations that lead to cancer. "We know that each cancer is a collection of genetic malfunctions," Raymond Cho, Ph.D., assistant clinical professor in the department of dermatology at the University of California, San Francisco, was quoted as saying. "We now know it...

Discovery could provide new target for drug development against conditions including heart attack, stroke and Parkinson's disease Scientists from the Florida campus of The Scripps Research Institute have uncovered a potentially important new therapeutic target that could prevent stress-related cell death, a characteristic of neurodegenerative diseases such as Parkinson's, as well as heart attack and stroke. In the study, published recently in the journal ACS Chemical Biology, the scientists...

In addition to its damaging effect on the environment and its illegal smuggling into developing countries, researchers have now linked e-waste to adverse effects on human health, such as inflammation and oxidative stress "“ precursors to cardiovascular disease, DNA damage and possibly cancer. In a study published today, Tuesday 31 May, in IOP Publishing's journal Environmental Research Letters, researchers took air samples from one of the largest e-waste dismantling areas in China and...

SINGAPORE, May 30, 2011 /PRNewswire-Asia/ -- Davos Life Science (DavosLife) has today announced preliminary results of a phase I clinical trial of its Natural e3 delta-tocotrienol (Natural e3) in patients with resectable pancreatic cancer. Tocotrienols are highly potent members of the Vitamin E family that have been found by researchers to inhibit the growth and survival of various types of cancer cells. This clinical trial revealed that Natural e3 was able to increase apoptosis (cell...

Weizmann Institute scientists reveal a new mechanism for keeping inflammation in check The molecular machines that defend our body against infection don't huff and puff, but some of them apparently operate on the same principle as a steam engine. Weizmann Institute scientists have discovered a mechanism that controls inflammation similarly to a steam-engine valve: Just when the inflammatory mechanism that protects cells against viruses reaches its peak of activity, the molecular...

Temptations to exceed the speed limit are always plentiful, but only reckless drivers give in to such impulses. Likewise, numerous growth factors always abound in our bodies, but only cancerous cells are quickly "tempted" by these chemicals to divide again and again. Healthy cells, in contrast, divide only after being exposed to growth factors for eight continuous hours. What happens during these eight hours in a healthy cell that resists the call to divide? And even more important, what...

Most degenerative diseases begin with a gradual loss of specific cell types that progresses, eventually leading to symptoms. For example, in type I diabetes, hyperglycemia commonly develops when approximately 80 percent of the beta cells in the pancreas are lost; in Parkinson's disease, motor dysfunction typically begins when neurons in a certain portion of the brain are decreased by 70 to 80 percent. Finding ways to stop early cell destruction is vital, but methods to do so have proven...

IDIBELL researchers at UB have tested this molecule antagonist of MDM2, a protein active in brain tumors Researchers of Apoptosis and Cancer Group of the Bellvitge Biomedical Research Institute (IDIBELL) have found that a small molecule, Nutlin-3a, an antagonist of MDM2 protein, stimulates the signalling pathway of another protein, p53. By this way, it induces cell death and senescence (loss of proliferative capacity) in brain cancer, a fact that slows its growth. These results open the door...

Researchers at The Wistar Institute have found a new way to force cancer cells to self-destruct. Low doses of one anti-cancer drug currently in development, called Gamitrinib, sensitize tumor cells to a second drug, called TRAIL, also currently in clinical development as part of an anticancer regimen. Their findings, published in the April issue of the Journal for Clinical Investigation, show how this combination approach kills tumor cells in both mouse models of glioblastoma and human...
