Research suggests blocking DNA repair complex helps fight therapy-resistant leukemia

New research posted online by the Nature journal Leukemia suggests blocking part of a DNA repair complex that helps some types of leukemia resist treatment can increase the effectiveness of chemotherapy and enhance survival.

Pregnant rats fed with high-fat diet experience preeclampsia-like syndromes

Preeclampsia is a relatively common pregnancy disorder, characterized by primary hypertension and proteinuria. In patients with severe preeclampsia, eclampsia can develop, causing nervous system symptoms and signs.

Study: Immune-regulating molecules can trigger lymphomas

A small group of immune-regulating molecules, when overproduced even moderately, can trigger the blood cancers known as lymphomas, according to a new study led by scientists from The Scripps Research Institute (TSRI).

Study: 3 enzymes required for building sugar superstructure involved in muscular dystrophies

For many inherited diseases, such as cystic fibrosis or Huntington disease, the disease-causing genetic mutation damages or removes a protein that has an essential role in the body. This protein defect is the root cause of the disease symptoms.

High mobility group (HMG) genes and cancer: an interview with Dr. Linda Resar, Johns Hopkins University School of Medicine

High mobility group A genes are highly expressed in all aggressive cancers studied to date. These genes encode the high mobility group A (HMGA) proteins. In other words, these genes provide the genetic “code” necessary to produce HMGA proteins.

DASA Group to offer Natera's non-invasive prenatal test for detection of genetic syndromes

DASA Group and Natera today announced that DASA Group will begin offering Natera's non-invasive prenatal test Panorama for the detection of genetic syndromes common in the population, such as trisomy 21 (Down syndrome), trisomy 13 (Patau Syndrome ), trisomy 18 (Edwards syndrome) and monosomy X (Turner syndrome).

Findings could lead to development of therapeutic agents for age-related diseases

Scientists at Sanford-Burnham Medical Research Institute have identified a key factor that regulates the autophagy process, a kind of cleansing mechanism for cells in which waste material and cellular debris is gobbled up to protect cells from damage, and in turn, modulates aging.

Penn State researchers find that protein changes can control gene functions

A Penn State-led research team has found that changes to proteins called histones, which are associated with DNA, can control whether or not a gene is allowed to function. The changes may be important in maintaining the genes' "expression potential" so that future cells behave as their parent cells did.

Biodegradable surgical sutures could treat brain infections

A plastic material already used in absorbable surgical sutures and other medical devices shows promise for continuous administration of antibiotics to patients with brain infections, scientists are reporting in a new study. Use of the material, placed directly on the brain's surface, could reduce the need for weeks of costly hospital stays now required for such treatment, they say in the journal ACS Chemical Neuroscience.

Overthinking can be harmful to human performance, finds study

Trying to explain riding a bike is difficult because it is an implicit memory. The body knows what to do, but thinking about the process can often interfere. So why is it that under certain circumstances paying full attention and trying hard can actually impede performance? A new UC Santa Barbara study, published today in the Journal of Neuroscience, reveals part of the answer.

Researchers unveil comprehensive portrait of the genome of world's first immortal cell line

A team from the University of Washington has unveiled a comprehensive portrait of the genome of the world's first immortal cell line, known as HeLa. The cell line was derived in 1951 from an aggressive cervical cancer that killed Henrietta Lacks, a 31-year-old African-American tobacco farmer and mother of five - the subject of the 2010 New York Times bestseller, The Immortal Life of Henrietta Lacks.

Ret enzyme may be a novel therapeutic target in selected groups of breast cancer patients

Scientists at the MedUni Vienna, in collaboration with a working group led by Nancy Hynes at the University of Basel, have discovered a new approach in the treatment of breast cancer: an international team involving the Clinical Institute of Pathology at the MedUni Vienna has been able to demonstrate the activation of a receptor, the Ret protein (Rearranged during transfection), on the surface of breast cancer cells. Increased levels of this protein are associated with a lower likelihood of survival for breast cancer patients.

Understanding the movement of neurons sheds light on how cancer cells invade health tissues

The invasion of brain-tumor cells into surrounding tissue requires the same protein molecule that neurons need to migrate into position as they differentiate and mature, according to new research from the University of Illinois at Chicago College of Medicine and published August 7 in the online journal PLOS ONE.

Research shows how mammalian and bacterial kingdoms interact

The bacteria Streptococcus pneumoniae harmlessly colonizes the mucous linings of throats and noses in most people, only becoming virulent when they leave those comfortable surroundings and enter the middle ears, lungs or bloodstream. Now, in research published in July in mBio, University at Buffalo researchers reveal how that happens.

AmpliPhi releases data on phage therapy for treatment of lung infections in Cystic Fibrosis patients

AmpliPhi BioSciences Corp. (OTC: APHB) ("AmpliPhi"), the leader in the development of bacteriophage-based antibacterial therapies to treat drug resistant bacterial infections, yesterday presented data relating to the use of bacteriophages in the treatment of Pseudomonas aeruginosa (P. aeruginosa) at the 20th Biennial Evergreen International Phage Meeting held in Olympia, Washington, USA. P. aeruginosa is the major cause of lung infections in cystic fibrosis (CF) patients.

Cognitive decline with age is natural part of life, OSU researchers find

If you forget where you put your car keys and you can't seem to remember things as well as you used to, the problem may well be with the GluN2B subunits in your NMDA receptors.

ASU expert receives $1.6 million grant to advance microscopy imaging research

At Arizona State University's Biodesign Institute, Nongjian (NJ) Tao has been designing advanced microscopy methods with the ambitious aim of capturing molecular-scale phenomena in living systems. The new techniques, which combine multiple imaging modalities, are poised to revolutionize the study of biology and the development of new drugs.
