Understanding genetic machinery that drives malignant pediatric adrenocortical tumors

In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the "genomic landscape" of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.

Snai1 protein plays major role in deciding fate of intestinal stem cells

An international group of researchers has shown that a regulatory protein involved in controlling how cancer spreads through the body also influences the fate of stem cells in the intestine of mice. The results, which are published in The EMBO Journal, show that the Snai1 protein plays an important role in deciding the fate of intestinal stem cells and the different functions that these cells can adopt.

M-MDSCs may be effective in treating arthritis in humans

Using a mouse model of rheumatoid arthritis, scientists have discovered that a form of cellular immunotherapy by intravenous administration of monocytic myeloid-derived suppressor cells, or M-MDSCs, might be an effective treatment for the disease in humans.

Better understanding of stomach's response to infection could lead to therapies against gastric damage

A better understanding of the stomach's immune response to Helicobater pylori (H. pylori) infection could lead to new therapies targeting damage in the stomach, report researchers in the March issue of Cellular and Molecular Gastroenterology and Hepatology, the basic science journal of the American Gastroenterological Association.

BUSM researchers discover genes involved in formation of lung tumors

The lung transcription factor Nkx2-1 is an important gene regulating lung formation and normal respiratory functions after birth. Alterations in the expression of this transcription factor can lead to diseases such as lung interstitial disease, post-natal respiratory distress and lung cancer.

Culture conditions in which stem cells are grown can affect genetic stability

The therapeutic promise of human stem cells is indisputably huge, but the process of translating their potential into effective, real-world treatments involves deciphering and resolving a host of daunting complexities.

CLL patients discontinue ibrutinib drug due to disease progression during clinical trials

About 10 percent of patients with chronic lymphocytic leukemia (CLL) discontinued therapy with the Bruton tyrosine kinase (BTK) inhibitor drug ibrutinib because of disease progression during clinical trials, according to a study published online in JAMA Oncology.

Scientists confirm relation between levels of certain pollutants in the body and levels of obesity

A team of Spanish scientists, which includes several researchers from the University of Granada, has confirmed that there is a relation between the levels of certain environmental pollutants that a person accumulates in his or her body and their level of obesity. Subjects with more pollutants in their organisms present besides higher levels of cholesterol and triglycerides, which are important risk factors for cardiovascular disease.

Researchers discover that cell's skeleton can trigger cell multiplication

A research team from Instituto Gulbenkian de Ciencia (IGC; Portugal), led by Florence Janody, in collaboration with Nicolas Tapon from London Research Institute (LRI; UK), discovered that the cell's skeleton can trigger the multiplication of cells through the action of proteins that control cellular rigidity.

Scientists find new links between inflammation and tissue regeneration

Almost all injuries, even minor skin scratches, trigger an inflammatory response, which provides protection against invading microbes but also turns on regenerative signals needed for healing and injury repair - a process that is generally understood but remains mysterious in its particulars.

Fat cell transplantation benefits systemic sclerosis patients with non-healing digital ulcers

Digital ulcers (DUs) are a frequent, painful, and quality of life altering complication for patients with systemic sclerosis (SSc), a connective tissue disease causing a progressive loss of small blood vessels and resulting changes in organs and tissues. DUs on the fingertips of SSc patients are slow to heal, if they heal at all, as many are unresponsive to any therapies.

New TAU study may offer hope to people diagnosed with Glioblastoma multiforme

There are no effective available treatments for sufferers of Glioblastoma multiforme (GBM), the most aggressive and devastating form of brain tumor. The disease, always fatal, has a survival rate of only 6-18 months.

Study shows that even breast cancers with few androgen receptors benefit from anti-androgen therapy

A University of Colorado Cancer Center study published today in the journal Molecular Cancer Therapeutics shows that only about 1 percent of triple-negative breast cancer cells in a tumor must be "androgen-receptor-positive" to show benefit from anti-androgen therapies.

Johns Hopkins scientists identify genetic pathway that may spur cancer cell growth in children

Working with cells taken from children with a very rare but ferocious form of brain cancer, Johns Hopkins Kimmel Cancer Center scientists have identified a genetic pathway that acts as a master regulator of thousands of other genes and may spur cancer cell growth and resistance to anticancer treatment.

Rigel, Bristol-Myers Squibb partner to develop, commercialize TGF beta receptor kinase inhibitors

Rigel Pharmaceuticals, Inc. and Bristol-Myers Squibb Company today announced that they have entered into a collaboration agreement for the discovery, development and commercialization of cancer immunotherapies based on Rigel's extensive portfolio of small molecule TGF beta receptor kinase inhibitors.

Researchers reveal new understanding of pathobiology behind vestibular schwannoma

Researchers from the Eaton-Peabody Laboratories of Massachusetts Eye and Ear and the Harvard Medical School/ Massachusetts Institute of Technology Program in Speech and Hearing Bioscience and Technology have revealed new understanding of the pathobiology behind a head and neck tumor that may someday lead to new methods of targeted drug therapy.

Researchers demonstrate clinical efficacy of gallopamil in severe asthma patients

A team of Inserm researchers from the Cardio-Thoracic Research Centre of Bordeaux (Inserm/University of Bordeaux and Bordeaux University Hospital) has demonstrated the clinical efficacy of gallopamil in 31 patients with severe asthma. This chronic disease is characterised by remodelling of the bronchi, which exacerbates the obstruction of the airways already seen in "classic" asthma.

Study results pave way for new clinical trial for glioblastoma patients

Immune cells engineered to seek out and attack a type of deadly brain cancer were found to be both safe and effective at controlling tumor growth in mice that were treated with these modified cells, according to a study published in Science Translational Medicine by a team from the Perelman School of Medicine at the University of Pennsylvania and the Novartis Institutes for BioMedical Research.

Research findings could someday lead to new treatments for patients with autism and cancer

In recent years, scientists have found a surprising a connection between some people with autism and certain cancer patients: They have mutations in the same gene, one that codes for a protein critical for normal cellular health. Now scientists have reported in the ACS journal Biochemistry that the defects reduce the activity and stability of the protein.
