UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

HIF-1a protein of hypoxia creates CD24 overexpression in many tumors

It seems as if a tumor deprived of oxygen would shrink. However, numerous studies have shown that tumor hypoxia, in which portions of the tumor have significantly low oxygen concentrations, is in fact linked with more aggressive tumor behavior and poorer prognosis.

Scientists describe how DNA origami can enhance effect of cytostatics in cancer treatment

Scientists at Karolinska Institutet in Sweden describe in a new study how so-called DNA origami can enhance the effect of certain cytostatics used in the treatment of cancer. With the aid of modern nanotechnology, scientists can target drugs direct to the tumour while leaving surrounding healthy tissue untouched.

SOX2 gene potential therapeutic target for SCLC

Expression of the Sry-related HMG box 2 gene is higher in small-celllung cancer tissue samples than in non-cancerous lung tissue samples, according to findings from a genetic study.

Pam2Cys nasal spray may be useful agent against pandemics and emerging viral strains

In an advance toward development of a nasal spray that protects against infection with influenza and spread of the disease, scientists are reporting identification of a substance that activates the first-line defense system against infection inside the nose. They describe effects of a synthetic form of a natural substance found in bacterial cell walls in ACS' journal Molecular Pharmaceutics.

Predicting breast cancer drug response by 20/20 GeneSystems’ PredicTOR test

20/20 GeneSystems, Inc. will present results this week at the Breast Cancer Symposium 2012 (San Francisco) of a 45 patient study showing the usefulness of its PredicTOR test in predicting response of breast tumors to the drug Herceptin.

Brigham Young University scientists discover cellular cause of birth defects

The cellular cause of birth defects like cleft palates, missing teeth and problems with fingers and toes has been a tricky puzzle for scientists. Now Professor Emily Bates and her biochemistry students at Brigham Young University have placed an important piece of the developmental puzzle. They studied an ion channel that regulates the electrical charge of a cell. In a new study published by the journal Development, they show that blocking this channel disrupts the work of a protein that is supposed to carry marching orders to the nucleus.

Case Western Reserve researcher discovers new antivirulence drugs against MRSA and strep

Menachem Shoham, PhD, associate professor of biochemistry at Case Western Reserve University School of Medicine, has discovered novel antivirulence drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) and Streptococcus pyogenes, commonly referred to as strep, harmless by preventing the production of toxins that cause disease.

Angiopoietin-like protein 2 level linked to incident diabetes

Elevated angiopoietin-like protein 2 levels are associated with the development of Type 2 diabetes, show findings from a Japanese study.

Researchers present new results from RV144 HIV vaccine trial at AIDS Vaccine 2012

"A paper published in Nature on Monday sheds light on how a vaccine can turn the immune system against [HIV] and so offer protection from infection," Nature News reports, noting "[t]he results are also being presented at the AIDS Vaccine 2012 conference in Boston, Massachusetts, this week."

Molecular insight into oxygen sensing mechanism

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's.

Berkeley lab researchers link possible new oncogene with resistance to cancer drugs

A gene that may possibly belong to an entire new family of oncogenes has been linked by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) to the resistance of breast cancer to a well-regarded and widely used cancer therapy.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

KRAS gene mutation recruits second player to trigger pancreatic cancer

More than a cancer-causing gene is needed to trigger pancreatic cancer, a study led by Mayo Clinic has found. A second factor creates a "perfect storm" that allows tumors to form, the researchers say. The study, published in the Sept. 10 issue of Cancer Cell, overturns the current belief that a mutation in the KRAS oncogene is enough to initiate pancreatic cancer and unrestrained cell growth.

Methodist Hospital develops new technology to rapidly detect drug-resistant TB

Technology developed by scientists at The Methodist Hospital Research Institute could halve the time it takes to diagnose tuberculosis infection, and also tell doctors in a day or two whether the bacteria are drug resistant -- a process that currently takes weeks. Initial tests of the device were recently described in Scientific Reports, a Nature online journal.

RNA researcher to receive 2012 Pearl Meister Greengard Prize from The Rockefeller University

Joan A. Steitz, Ph.D., a pioneer in the field of RNA biology whose discoveries involved patients with a variety of autoimmune diseases, will be awarded the 2012 Pearl Meister Greengard Prize from The Rockefeller University. The prize, which honors female scientists who have made extraordinary contributions to biomedical science and carries an honorarium of $100,000, will be presented at a ceremony on Thursday, November 29 at Rockefeller University's Caspary Auditorium.
