TGF-betaR inhibitors may counter drug resistance in cancer patients with MED12 mutations

Cancer therapies often have short-lived benefits due to the emergence of genetic mutations that cause drug resistance. A key gene that determines resistance to a range of cancer drugs has been reported in a study published by Cell Press November 21st in the journal Cell.

Heidelberg researchers uncover function of specific molecular chaperones

Clumped proteins can be dissolved with the aid of cellular repair systems - a process of critical importance for cell survival especially under conditions of stress. Heidelberg researchers have now decrypted the fundamental mechanism for dissolving protein aggregates that involves specific molecular chaperones.

UPR pathway helps tumor cells escape apoptosis during development of lymphoma

A pathway called the "Unfolded Protein Response," or UPR, a cell's way of responding to unfolded and misfolded proteins, helps tumor cells escape programmed cell death during the development of lymphoma.

Scientists extract recent drug trials to tackle Alzheimer's earlier than ever before

Alzheimer's therapeutic trials have gotten bad press lately, but it is not all gloom and doom. As evident at the 5th Clinical Trials in Alzheimer's Disease (CTAD) conference, held 29-31 October in the Principality of Monaco, scientists keep extracting new data from recent drug trials to gear up for a round of new ones that aim to tackle Alzheimer's earlier than ever before.

Study shows how Parkinson's spreads and leads to nerve cell death

Understanding how any disease progresses is one of the first and most important steps towards finding treatments to stop it. This has been the case for such brain-degenerating conditions as Alzheimer's disease. Now, after several years of incremental study, researchers at the Perelman School of Medicine, University of Pennsylvania have been able to piece together important steps in how Parkinson's disease (PD) spreads from cell to cell and leads to nerve cell death.

New pathway appears to play a major role in information processing in the brain

Scientists at The Scripps Research Institute (TSRI) have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

Stapled Peptide oncology drug candidate exhibits robust efficacy in xenograft cancer models

Aileron Therapeutics, Inc. and its collaborator Roche today announced new results of a preclinical study of its Stapled Peptide oncology drug candidate ATSP-7041, which exhibited robust efficacy in MDM2 and MDMX xenograft cancer models.

Carbohydrate-rich food intake may cause recurrence of colon cancer

Colon cancer survivors whose diet is heavy in complex sugars and carbohydrate-rich foods are far more likely to have a recurrence of the disease than are patients who eat a better balance of foods, a new study by Dana-Farber Cancer Institute researchers indicates.

Excessive turnover of placental cells may trigger unnatural increase in blood pressure

Excessive turnover of cells in the placenta may trigger an unnatural increase in blood pressure that puts mother and baby at risk, researchers say.

Drug trio may reduce eliminate cardiac side effects of doxorubicin

Combining cancer medication with a drug for erectile dysfunction and one for heart transplants helped kill cancer cells and protected the heart from damage, in a study presented at the American Heart Association's Scientific Sessions 2012.

Selective blocking of HDAC11 inhibitor would act exclusively on tumor cells

Several substances inhibiting so-called HDAC enzymes have been studied in trials searching for new anti-cancer drugs in recent years. "Trials have shown that HDAC inhibitors are very effective in arresting growth of cultured cancer cells. But apart from a very rare type of lymphoma, these drugs unfortunately do not clinically affect malignant tumors," says Prof. Dr. Olaf Witt, who heads a research department at DKFZ and is pediatrician at the Center for Child and Adolescent Medicine of Heidelberg University Hospital.

Researchers analyse hydrogen bonds in tiny fibrils of amyloid-beta peptide

Using solid-state nuclear magnetic resonance (NMR) spectroscopy, researchers at Luleå University of Technology in collaboration with Warwick University in the UK for the first time in the world managed to analyse hydrogen bonds in tiny fibrils of Amyloid-beta peptide , which probably causes Alzheimer's disease.

Vitamin D deficiency: an interview with Kellie Bilinski

We know that vitamin D is important in keeping bones strong. In the last 30-40 years it has also been realized that vitamin D has a lot of other roles in the body. Vitamin D essentially has a role in any cell in the body that has a vitamin D receptor.

XJB-5-131 compound suppresses symptoms of Huntington's in mice

There's new hope in the fight against Huntington's disease. A group of researchers that includes scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.

Study describes role of TFIIB protein in helping cells repair DNA damage

In a new study, University at Buffalo scientists describe the role that a protein called TFIIB plays in helping cells repair DNA damage, a critical function for preventing the growth of tumors.

Study identifies monoacylglycerol lipase as new therapeutic target to treat Alzheimer's

Research led by Chu Chen, PhD, Associate Professor of Neuroscience at LSU Health Sciences Center New Orleans, has identified an enzyme called Monoacylglycerol lipase (MAGL) as a new therapeutic target to treat or prevent Alzheimer's disease.

CSHL scientists discover new way to specifically target and kill cancer cells

Cancer cells grow fast. That's an essential characteristic of what makes them cancer cells. They've crashed through all the cell-cycle checkpoints and are continuously growing and dividing, far outstripping our normal cells. To do this they need to speed up their metabolism.

Nisin may slow or prevent squamous cell head and neck cancers

Nisin, a common food preservative, may slow or stop squamous cell head and neck cancers, a University of Michigan study found.

Ischemic stroke: an interview with Dr Gregory Ford

A stroke is a sudden interruption of blood flow to the brain which deprives the brain of oxygen and nutrients. Approximately two millions brain cells die each minute during a stroke. This can lead to brain damage, physical and mental disability and death.

Pins made of single atoms to fight cancer

Answers are often elusive in the fight against cancer, and Rice University chemist Zachary Ball is hoping to pin one down -- with pins made of single atoms. The work, which aims to create a drug that's effective against an "undruggable" protein, is one of the first 50 proposals funded under the National Cancer Institute's (NCI) Provocative Questions Project.
