More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.

Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.

International Microbicides Conference to discuss state of HIV prevention research

Researchers, activists and funders are meeting this week in Sydney to discuss the state of HIV prevention research. The biennial International Microbicides Conference, which was opened on Sunday evening by the Honorable Tanya Plibersek MP, Australian Minster of Health, is taking place amid renewed optimism about development and delivery of new HIV prevention options with the potential for ending the AIDS epidemic, including anti-retroviral based microbicides and pre-exposure prophylaxis.

Hydrophilic carbon cluster HADES can selectively kill brain cancer cells

Nanomedicine researchers at the Methodist Neurological Institute and Rice University have developed a way to selectively kill brain cancer cells by using a tiny syringe to deliver a combination of chemotherapy drugs directly into the cells. These findings will be published in the April 24 issue of the American Chemical Society journal ACS Nano.

ThromboGenics resubmits ocriplasmin BLA with FDA to treat symptomatic VMA

ThromboGenics NV, a biopharmaceutical company focused on developing innovative ophthalmic medicines, today announced that it has resubmitted a Biologics License Application (BLA) with the U.S. Food and Drug Administration (FDA) for ocriplasmin intravitreal injection, 2.5 mg/mL, for the treatment of symptomatic Vitreomacular Adhesion (VMA) including macular hole.

Steroids still work better for patients with sciatica

Despite the great promise that injecting a new type of anti-inflammatory pain medicine into the spine could relieve the severe leg and lower back pain of sciatica, a Johns Hopkins-led study has found that the current standard of care with steroid injections still does better.

Study pinpoints compounds that repress cancer gene’s activity

A research team pursuing one of the most commonly altered genes in cancer has laid a critical foundation for understanding this gene that could point the way toward developing drugs against it. A recent study of cancer genetics pointed to the gene MCL1, which encodes a protein that helps keep cells alive

32 genetic variations could play a role in osteoporosis risk

A team of international researchers have found 32 new genetic regions linked to fractures and osteoporosis. According to the new study published in the April 15 online edition of Nature Genetics, changes in these regions could offer protection from, or greater risk for, bone-weakening disease.

Immunotherapy may also help elderly cancer patients

Cancer is much more likely in the elderly than the young, and their bodies often are less prepared to fight the disease and the often-toxic side effects of treatment.

Decreasing GPA adherence among COX-2 users increases risk of upper GI complications

To relieve pain, arthritis sufferers are prescribed medications that may include non-steroidal anti-inflammatory drugs (NSAIDs) or cyclooxygenase-2 (COX-2) inhibitors, both of which can irritate the digestive tract. At times additional drugs are co-prescribed with NSAIDs or COX-2 inhibitors to prevent adverse gastrointestinal (GI) effects.

TGF-β molecule ramps up the immune system in some cases and suppress it in others

Loyola researchers are reporting surprising findings about a molecule that helps ramp up the immune system in some cases and suppress it in others.

Panel discussion on personalized medicine at USciences

Advances in fields such as genetics and genomics have created new opportunities for personalized medicine applications in clinical practice and the healthcare delivery. This integration raises important questions about how personalized medicine can best help patients without increasing costs and improving health outcomes.

'Mental health checkups' as part of health care in schools

"The early detection of children who are showing psychiatric symptoms or are at the risk of a mental disorder is crucial, but introducing "mental health checkups" as part of health care in schools is not altogether simple," says David Gyllenberg, MD, whose doctoral dissertation "Childhood Predictors of Later Psychotropic Medication Use and Psychiatric Hospital Treatment - Findings from the Finnish Nationwide 1981 Birth Cohort Study" was publically examined at the University of Helsinki on 13 April 2012.

UM hosts symposium on next generation characterization tools for therapeutic proteins

In a concerted effort to boost regional collaboration on developing new protein drug and diagnostics, the University of Maryland (UM) School of Pharmacy has hosted the first Interdisciplinary Symposium on Next Generation Characterization Tools for Therapeutic Proteins.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Research roundup: Obesity treatment for low-income patients; Medicare vs. private plans

Low-income patients are underrepresented in clinical trials and are disproportionately prone to obesity and the related problems of high blood pressure and heart disease. Researchers conducted a 24-month trial of more than 300 low-income, obese patients from various Boston community health centers, randomizing participants "to usual care or a behavioral intervention that promoted weight loss and hypertension self-management using eHealth components. The intervention included tailored behavior change goals, self-monitoring, and skills training, available via a website or interactive voice response."

$Researchers identify 32 genetic regions associated with osteoporosis, fracture$

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.

Researchers identify new mechanism by which colon cancer develops

A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discovered a set of master switches, i.e., gene enhancer elements, that turn "on and off" key genes whose altered expression is defining for colon cancers.
