Scientists develop new method to directly identify miRNA targets in cells

Human cells are thought to produce thousands of different microRNAs (miRNAs)-small pieces of genetic material that help determine which genes are turned on or off at a given time. miRNAs are an important part of normal cellular function, but they can also contribute to human disease-some are elevated in certain tumors, for example, where they promote cell survival.

New light on many biological differences between individual breast cancers

New findings presented at Europe's leading breast cancer translational research conference this year shed new light on the many biological differences between individual breast cancers.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

IMPAKT 2012 breast cancer conference to focus on four major areas

"Basic science and clinical medicine move at different pace because they follow different paths. Both however aim at improving strategies to manage cancer patients. We need to efficiently translate the good things from basic science and efficiently implement them in the clinic."

Developing organisms can identify and repair head and facial abnormalities

Developmental biologists at Tufts University have identified a "self-correcting" mechanism by which developing organisms recognize and repair head and facial abnormalities. This is the first time that such a mechanism has been reported for the face and the first time that this kind of flexible, corrective process has been rigorously analyzed through mathematical modeling.

P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Study shows how acupuncture therapy holds promise for skeletal muscle atrophy

A team of Japanese researchers will reveal study results Monday at the Experimental Biology 2012 meeting that show how acupuncture therapy mitigates skeletal muscle loss and holds promise for those seeking improved mobility through muscle rejuvenation.

Study determines importance of bacterial infections in cirrhosis

A South African study presented today determines the importance of bacterial infections, which commonly occur in cirrhosis and can alter the natural history of the condition, possibly leading to loss of liver function and decompensation. It is now recognised that many infections in cirrhotic patients result from bacterial translocation (BT) from the intestine.

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes

Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell.

Keck Foundation awards UF $1M to study how proteins in cells are made

The Center for NeuroGenetics at the University of Florida has received a competitive $1 million grant from the W.M. Keck Foundation to study a new idea that challenges conventional understanding of how proteins in cells are made, and their impact on inherited diseases.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

Black fly's blood-sucking tactics may be used for medical advancement

Black flies drink blood and spread disease such as river blindness-creating misery with their presence. A University of Georgia study, however, proves that the pesky insects can be useful.

Two Rev-erb proteins work together to control fat metabolism

The 24-hour internal clock controls many aspects of human behavior and physiology, including sleep, blood pressure, and metabolism. Disruption in circadian rhythms leads to increased incidence of many diseases, including metabolic disease and cancer. Each cell of the body has its own internal timing mechanism, which is controlled by proteins that keep one another in check.

Aberrations in translation regulators linked with hormone receptor-positive breast cancer survival

Four proteins involved in translation, the final step of general protein production, are associated with poor prognosis in hormone-receptor-positive breast cancer when they are dysregulated, researchers reported at the AACR Annual Meeting 2012.

New project to focus on role of Myc oncoproteins in B-cell lymphoma

The National Institutes of Health has awarded The Scripps Research Institute $2 million to study the role of a pathway in the development and maintenance of B-cell lymphoma, a type of cancer that begins in immune system and turns normal disease fighting cells into cancers. The disease affects immune cells known as lymphocytes, which are part of our white blood cells.

NanoString to launch 3 new products for nCounter Analysis System at AACR 2012

NanoString Technologies, Inc., a privately held provider of life science tools for translational research and developer of molecular diagnostics, today announced that it will launch three new products for the nCounter Analysis System at the American Association of Cancer Research (AACR) Annual Meeting 2012, March 31-April 4, in Chicago, Ill.

Researchers discover MicroRNAs as new switch of adipose cell development

Hunger has always threatened mankind. This makes it unsurprising that human bodies attempt to store all surplus nourishment in adipose tissue. In developed countries, this life-saving craving is turning into a problem and obesity—adiposity—is turning into a danger. Why, though, does excess fat the body ill? How does fat trigger diabetes? And can these superfluous fat reserves be turned into warmth and just as well burnt?

Protein precursors destined for spiny extensions of neurons travel single file

Protein precursors destined for the spiny extensions of neurons travel single file, according to a study by Sanjay Tyagi, PhD, and colleagues at the University of Medicine and Dentistry of New Jersey.

Study reveals central role played by DBIRD protein complex in gene transcription

In a study published this week in the journal Nature, researchers at the University of Liège's GIGA Unit, together with English and German teams, reveal the central role played by a protein complex, unknown up to now, in gene transcription.
