Roche's xCELLigence RTCA SP Instrument used for in vitro testing of cells

The C-terminal domain (CTD) of RNA Polymerase II consists of multiple repeats of an evolutionary conserved motif of seven amino acids, forming a repetitive structure of 52 repeats in humans and 26 repeats in yeast. Twenty years after the first description of the RNA polymerase II C-terminal domain, its function is still unclear.

Increasing insulin levels can aid muscle building in the elderly

Recently, scientists have recognized that loss of responsiveness to insulin plays a major role in the loss of physical strength that occurs as people grow older. Now, University of Texas Medical Branch at Galveston researchers have demonstrated that by increasing insulin levels above the normal range in elderly test subjects, they can restore the impaired muscle-building process responsible for age-related physical weakness.

TSPs can block cancer-triggering proto-oncogenes

A tiny bit of genetic material with no previously known function may hold the key to stopping the spread of cancer, researchers at Yale School of Medicine and Sichuan University in Chengdu, China report in two papers in the September 7-11 issue of Proceedings of the National Academy of Sciences.

Researchers visualize vasculature within native liver cyst walls of human ADPKD patients

As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body of the liver and that factors released by epithelial cells that line the liver cyst wall lumen can drive the proliferation and development of vascular endothelial cells.

Phase 2 trial results of Bayer's Nexavar in combination with capecitabine announced

Bayer HealthCare Pharmaceuticals and Onyx Pharmaceuticals, Inc. (Nasdaq: ONXX) today announced the full results from their first collaborative group-sponsored randomized, double-blind, placebo-controlled Phase 2 trial showing that Nexavar(R) (sorafenib) tablets in combination with the oral chemotherapeutic agent, capecitabine, significantly extended progression-free survival in patients with advanced breast cancer.

Study reveals that YAP can be used for the diagnosis of gastric carcinoma

A research team led by Professor Yan Xin, from The Fourth Laboratory of Cancer Institute in China measured the expression of YAP and survivin in normal gastric mucosa, precancerous lesions and gastric carcinoma using an immunohistochemical method to analyze the significance and correlations of the 2 factors with gastric carcinogenesis.

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 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.
