Researchers identify promising new therapies for ependymoma

Researchers have identified promising new therapies for ependymoma, a rare tumor with few treatment options. St. Jude Children's Research Hospital investigators led the effort, which used a new, faster drug development system that combines the latest drug screening technology with the first accurate animal model of the tumor.

Scientists decode new mechanism that regulates cell polarity in epithelial tissues, neurons

In the course of examining the Drosophila tumor suppressor gene (Dlg), scientists at the Helmholtz Zentrum München have succeeded in decoding a new mechanism that regulates cell polarity in epithelial tissues or in neurons in the brain.

Researchers discover group of mutations involved in T-cell acute lymphoblastic leukemia

An international team of researchers has found a group of mutations involved in T-cell acute lymphoblastic leukemia (T-ALL), and showed that a group of certain drugs, already in clinical use to treat other diseases, can eliminate the cells carrying these mutations.

Scientists identify human colon stem cells and grow them in lab-plates

Human colon stem cells have been identified and grown in a lab-plate for the first time. This achievement, made by researchers of the Colorectal Cancer Lab at the Institute for Research in Biomedicine and published in Nature Medicine, is a crucial advance towards regenerative medicine.

Researchers discover mechanism of low-dose LDN on cell proliferative-related disorders

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered the mechanism by which a low dose of the opioid antagonist naltrexone (LDN), an agent used clinically to treat cancer and autoimmune diseases, exerts a profound inhibitory effect on cell proliferation.

Study: Growth hormone helps regenerate damaged hair cells in zebrafish ear

Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible, however both birds and fish are able to re-grow the damaged hair cells and restore hearing.

Mayo Clinic and IC-MedTech enter collaborative research agreement with Summa Health System

Researchers from the Mayo Clinic and representatives from IC-MedTech signed a collaborative research agreement with Summa Health System to study the usage of Apatone, a proprietary combination of Vitamin-C and Vitamin-K3.

Specific inhibitor of microRNA-100 can stimulate development of new blood vessels

A specific inhibitor of the small regulatory RNA-molecule "microRNA-100" can be used to stimulate the growth of new blood vessels, if a major artery is chronically occluded.

Saffron promotes apoptosis and inhibits growth of cancerous cells

New research suggests that saffron provides a significant chemopreventive effect against liver cancer in animal models. When saffron was administered to rats with diethylnitrosamine (DEN)-induced liver cancer an inhibition of cell proliferation and stimulation of apoptosis was observed. Full findings appear in the September issue of Hepatology, a journal published by Wiley Blackwell on behalf of the American Association for the Study of Liver Diseases.

EMA accepts Merck and ARIAD's MAA for ridaforolimus to treat metastatic bone sarcomas

Merck, known outside the United States and Canada as MSD, and ARIAD Pharmaceuticals, Inc., today announced that the European Medicines Agency (EMA) has completed its administrative validation process for the regulatory application for ridaforolimus, an investigational oral mTOR inhibitor developed for the treatment of metastatic soft-tissue or bone sarcomas in patients who had a favorable response to chemotherapy.

Drug SLM3 prevents multiplication of tumor cells

Tumors that do not respond to chemotherapy are the target of a cancer therapy that prevents the function of two enzymes in mouse tumor cells, according to Pennsylvania medical researchers.

Scientists define relationship between two prostate tumor suppressor genes

Of the 250,000 American men who will be diagnosed with prostate cancer this year, very few of them-about 1 percent-will develop lethal, metastatic disease. Finding a way to distinguish between this small cohort and the majority of patients who will develop an indolent, non-lethal form of prostate cancer is a key goal in prostate cancer research.

Researchers explain why vertebrate intestines are so predictably loopy

Between conception and birth, the human gut grows more than two meters long, looping and coiling within the tiny abdomen. Within a given species, the developing vertebrate gut always loops into the same formation-however, until now, it has not been clear why.

Blocking type 2 receptor reduces PDA cell growth with the activation of AMPK enzyme

Pancreatic cancer researchers at Thomas Jefferson University have shown, for the first time, that blocking a receptor of a key hormone in the renin-angiotensin system (RAS) reduces cancer cell growth by activating the enzyme AMPK to inhibit fatty acid synthase, the ingredients to support cell division.

New method of delivering growth factors could lead to revolutionary heart treatment

Ever since the Nobel Prize for nerve growth factor was awarded more than 30 years ago, researchers have been searching for ways to use growth factor clinically.

Human kinome RNAi screening performed using Roche’s xCELLigence MP Instrument

RNA interference studies are a powerful technology for high-throughput screening. However, endpoint analyses only provide a snapshot of the analyzed cellular phenotype, as it is not possible to measure developmental changes over time.

Cigarette smoke exposure alters airway tissue in people with COPD

Cigarette smoke exposure fundamentally alters airway tissue from people with chronic obstructive pulmonary disease (COPD) at the cellular level, laying the groundwork for airway thickening and even precipitating precancerous changes in cell proliferation that may be self-perpetuating long after cigarette smoke exposure ends, according to Australian researchers.

New preclinical data suggests microRNA-15 inhibits cardiomyogenesis

miRagen Therapeutics, Inc., a biopharmaceutical company focused on improving patients' lives by developing innovative microRNA (miRNA)-based therapeutics for cardiovascular and muscle disease, announced today that new preclinical data published in the online edition of Circulation Research suggests that microRNA-15 (miR-15) inhibits cardiomyogenesis, the process whereby new heart muscle cells are formed.

New details about how dendritic cells regulate fate of naive T cells

St. Jude Children's Research Hospital scientists show that the molecule serves as a bridge between the two arms of the immune system that provides a new mechanism guiding T cell differentiation.

USPTO issues patent for Mirna's tumor suppressor microRNAs

Mirna Therapeutics, Inc. announced today that the United States Patent and Trademark Office has allowed multiple patent claims related to the therapeutic application of several tumor suppressor microRNAs.
