Trevena commences TRV130 Phase I clinical trial for severe post-operative pain

Trevena, Inc., the leader in discovery and development of G-protein coupled receptor (GPCR) biased ligands, announced today the initiation of a Phase I clinical trial of TRV130, a novel candidate designed for the intravenous treatment of moderate-to-severe post-operative pain.

Molecular secrets behind halofuginone's power

For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, a compound derived from this extract's bioactive ingredient, could be used to treat many autoimmune disorders as well. Now, researchers from the Harvard School of Dental Medicine have discovered the molecular secrets behind this herbal extract's power.

Inhibiting MET signaling in glioblastoma has major therapeutic value

A recent discovery by Van Andel Research Institute (VARI) scientists enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma - the most common and most aggressive malignant brain tumor in humans.

Researchers identify critical cellular, molecular events that lead to esophageal adenocarcinoma

Researchers at Columbia University Medical Center (CUMC) have identified the critical early cellular and molecular events that give rise to a type of esophageal cancer called esophageal adenocarcinoma, the fastest-rising solid tumor in the United States.

Study shows how to stop brain cancer cell proliferation and migration

Brain cancer is hard to treat: it's not only strong enough to resist most chemotherapies, but also nimble enough to migrate away from radiation or surgery to regrow elsewhere. New research at the University of Colorado Cancer Center shows how to stop both.

Insight into brain mechanism that limits rewarding impact of cocaine

Research published by Cell Press in the January 12 issue of the journal Neuron provides fascinating insight into a newly discovered brain mechanism that limits the rewarding impact of cocaine. The study describes protective delayed mechanism that turns off the genes that support the development of addiction-related behaviors.

Insulin induces formation of new elastin in cultures of human aortic smooth muscle cells

New research reveals that insulin applied in therapeutic doses selectively stimulates the formation of new elastic fibers in cultures of human aortic smooth muscle cells.

Van Andel studies distinguish cancer subtypes and provide promising new drug targets

Two recent studies by Van Andel Research Institute scientists are providing a foundation for a more complete understanding of distinct kidney cancer subtypes, which could pave the way for better treatments.

Scientists discover mechanism by which TNFα stimulates tumor formation

An inflammation-promoting protein triggers deactivation of a tumor-suppressor that usually blocks cancer formation via the NOTCH signaling pathway, a team of researchers led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell.

Researchers discover miR-520 blocks cancer-promoting signaling pathway

MicroRNAs or miRNAs are tiny RNA molecules that have only about 20 nucleotides and do not code for proteins. They regulate many important processes in cells by binding to target messenger RNAs - the instructions for protein production -, thus blocking production of the respective protein. In cancer, the production of some miRNAs is often reduced or amplified. This particularly affects miRNAs that regulate the activity of cancer-promoting genes.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Researchers discover how statins promote breakdown of plaque in arteries

In a new study, NYU Langone Medical Center researchers have discovered how cholesterol-lowering drugs called statins promote the breakdown of plaque in the arteries. The study was published online by the journal PLoS One on December 6, 2011.

Onconova announces data from five rigosertib clinical trials on MDS

Onconova Therapeutics announces three presentations relating to clinical trials of its Phase III-stage anticancer agent, rigosertib sodium (Estybon or ON 01910.Na), at the 53rd American Society of Hematology (ASH) Annual Meeting in San Diego, CA, December 10-13, 2011.

Researchers reveal how podocytes may regenerate themselves during normal kidney function

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function.

Scientists use genetic methods to successfully repair cleft lips in mice embryos

Scientists at Weill Cornell Medical College used genetic methods to successfully repair cleft lips in mice embryos specially engineered for the study of cleft lip and cleft palate. The research breakthrough may show the way to prevent or treat the conditions in humans.

New way to exploit expression of BRAF by papillary carcinomas for therapeutic purposes

Papillary carcinoma is the most common form of thyroid cancer. Approximately one quarter of these carcinomas have mutations in the BRAF gene. The prevalence of such mutations is even greater in high-grade carcinomas, particularly those that are refractory to standard treatment, which is radioactive iodine.

NYU Langone cardiovascular experts present new research findings at AHA 2011

Experts from the Cardiac & Vascular Institute at NYU Langone Medical Center presented new research findings at the American Heart Association Scientific Sessions 2011 held November 12-16, 2011 in Orlando, Florida.

Study demonstrates how DISC1 variants affect brain development

Significant progress has been made in understanding the genetic risk factors underlying psychiatric disease. Recent studies have identified common genetic mutations conferring modest risk and rare variants comprising significant risk. One example of a rare cause of psychiatric disorders is the Disrupted in Schizophrenia-1 (DISC1) gene, first identified in a large Scottish pedigree displaying schizophrenia, bipolar disorder and depression.

Study confirms link between CMV and mucoepidermoid carcinoma

An important new study from the Laboratory for Developmental Genetics at USC has confirmed cytomegalovirus (CMV) as a cause of the most common salivary gland cancers. CMV joins a group of fewer than 10 identified oncoviruses - cancer-causing viruses - including HPV.
