Phase III clinical trial results of DAR-31 published

Gilead Sciences, Inc. today announced the publication of data from DAR-311 (DORADO), a Phase III clinical trial evaluating the company’s once-daily oral endothelin receptor antagonist (ERA) darusentan as an add-on treatment for resistant hypertension, defined as the failure to achieve blood pressure goal while adhering to full doses of an appropriate three (or more) drug antihypertensive regimen that includes a diuretic.

Roche scientists use their xCELLigence System to analyze nutlin-induced apoptosis

The p53 tumor suppressor, a transcription factor that activates or inhibits hundreds of genes, either directly or indirectly, triggers a variety of cellular effects and plays a central role in the cellular defense against cancer. One of the main approaches for pharmacological intervention is to activate wild-type p53 in cancer cells by blocking MDM2 from binding to p53.

PKCiota oncogene essential for lung cancer stem cell proliferation

Scientists at the Mayo Clinic campus in Florida have found that the lung cancer oncogene PKCiota is necessary for the proliferation of lung cancer stem cells. These stem cells are rare and powerful master cells that manufacture the other cells that make up lung tumors and are resistant to chemotherapy treatment.

Study reveals the mechanisms of sodium tungstate in treating diabetes

The molecular mechanisms of tungstate activity in diabetes have been uncovered. Researchers writing in the open access journal BMC Genomics have identified the pathways through which sodium tungstate improves pancreatic function and beta cell proliferation.

Study suggests that connective tissue growth factor plays a vital role in liver fibrosis progression

Accumulating evidence suggests that connective tissue growth factor (CCN2) plays a central role in fibrotic conditions in many organ systems. Fibrosis is a scarring condition that is characterized by excessive collagen production that impedes normal cell function and can cause organ dysfunction and failure.

Tiny filaments extending from cells may play a role in common malignant brain tumors

UCSF scientists have discovered that a tiny filament extending from cells, until recently regarded as a remnant of evolution, may play a role in the most common malignant brain tumor in children.

Aspirin improves survival after colorectal cancer diagnosis

Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA.

Sigma-Aldrich offers customizable synthetic extracellular matrix (ECM) for stem cell research

Sigma-Aldrich (Nasdaq: SIAL) today announced an agreement with Glycosan BioSystems for the sale of HyStem(TM), a fully customizable synthetic extracellular matrix (ECM) for stem cell research. HyStem offers researchers flexibility to tailor microenvironments for their cultured cells that mimic natural in vivo conditions, optimizing stem cell proliferation and differentiation. HyStem was developed by Glycosan BioSystems and will be sold by Sigma-Aldrich under a non-exclusive distribution agreement.

Discovery of cells responsible for bladder cancer spread

Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread using a technique that takes advantage of similarities between tumor and organ growth. The findings, reported in the July Stem Cells, could help scientists develop new ways of finding and attacking similar cells in other types of cancer.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Caspase-8 protein plays an important role in proliferation and invasion of cancer cells

Scientists at Burnham Institute for Medical Research have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on June 15.

Discovery of key protein for tumor suppression in ER+ breast cancer

Researchers from the Kimmel Cancer Center at Jefferson have identified a protein relationship that may be an ideal treatment target for ER+ breast cancer. The study was reported in the July 15 issue of Cancer Research.

Discovery of four new breast cancer targets

Four suspects often found at the scene of the crime in cancer are guilty of the initiation and progression of breast cancer in mice that are resistant to the disease, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the June edition of Cancer Cell.

A new method for breast cancer biomarker discovery

Three researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.
