Presence of protein PARP in tumours may help predict response to chemotherapy

The presence of the protein poly (ADP-ribose) polymerase (PARP) in tumours can help predict their response to chemotherapy, a German scientist will tell the seventh European Breast Cancer Conference (EBCC7) in Barcelona tomorrow (Saturday 27 March). Professor Gunter von Minckwitz, from the German Breast Group Forschungs GmBH, Neu-Isenburg, says that, contrary to current belief that PARP is associated with a limited number of tumours, he and his team found for the first time that PARP expression exists across all breast cancer subtypes, and that such tumours were highly sensitive to chemotherapy.

Avid, Cardinal Health partner to detect Alzheimer's disease in living patients

Currently, Alzheimer's disease cannot be definitively diagnosed until after death, when a brain autopsy is performed on a patient and evidence of beta-amyloid plaque deposits in the brain – which are a characteristic pathology of the disease – can be found. Accurate diagnosis during life can be challenging, particularly in the early stages of Alzheimer's, when symptoms are mild and non-definitive. However, Avid Radiopharmaceuticals, Inc. and Cardinal Health are working together to change that.

Pravastatin benefits elderly carriers of KIF6 gene variant with prior vascular disease

Celera Corporation today announced the publication of data reporting that elderly (over age 70) carriers of the KIF6 gene variant with prior vascular disease received significant benefit from pravastatin (Pravachol®) therapy. Previous research has shown that a variant of the KIF6 gene, a member of the molecular motor protein kinesin family, is associated with up to a 55% increased risk of primary and recurrent coronary heart disease (CHD) events in the placebo arms of the clinical trials, and that this increased risk is virtually eliminated with statin therapy.

Roche NimbleGen' s microarray technologies help identify genes responsible for CRC

In a recently published study in the journal Genome Research, a team of scientists led by Dr. Shaying Zhao at the University of Georgia have developed a novel cross-species comparative genomics and oncology strategy for cancer driver gene discovery, using microarray technologies from Roche NimbleGen, that differs fundamentally from current approaches which focus on human cancers only.

Tumors mimic lymphoid tissue and alter host's immune response

A new mechanism explaining how tumors escape the body's natural immune surveillance has recently been discovered at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland. The study shows how tumors can create a tolerant microenviroment and avoid attack by the immune system by mimicking key features of lymph nodes.

Working of master regulator protein phosphatase 1

Protein phosphorylation is a process by which proteins are flipped from one activation state to another. It is a crucial function for most living beings, since phosphorylation controls nearly every cellular process, including metabolism, gene transcription, cell-cycle progression, cytoskeletal rearrangement and cell movement.

Modified protein plays a key role in memory processes

How do we process thoughts and store memories? A team of researchers headed by Dr. Nahum Sonenberg of McGill's Department of Biochemistry and Goodman Cancer Centre has discovered that brains in mammals modify a particular protein in a unique way, which alters the protein's normal function.

New experiments may hold clues for controlling cancer

A protein discovered in fruit fly eyes has brought a Johns Hopkins team closer to understanding how the human heart and other organs automatically "right size" themselves, a piece of information that may hold clues to controlling cancer.

Targeting Wnt/beta-catenin pathway may prevent growth and development of AML: Study

About 40 percent of children and up to 70 percent of adults in remission from acute myelogenous leukemia will have a relapse. In recent years, doctors have come to believe that this is due to leukemia stem cells, endlessly replicating cancer cells that generate the immature blood cells characteristic of leukemia and are resistant to typical cancer treatments.
