Novel and more effective way of testing which gene mutations cause cancer

Often cancer research goes like this: study cancerous cells in a lab dish, find mutations that appear in many of the samples, develop drugs to target proteins made by the mutated genes, and voila, new chemotherapy drugs are born. Or at least that's the hope.

Researchers discover how microRNA are involved in the development of heart muscle

Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle.

Bio-engineered skin provides clues to melanoma development

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine.

Genetic variations predispose Mexican Americans to insulin resistance

Although numerous studies have shown that low-grade inflammation is linked to heart disease and diabetes, more recent studies have shown that inflammation plays a role in insulin resistance, a syndrome that leads to diabetes and heart disease and affects about one in four adults in the United States.

Link between PKC enzyme and kidney disease in diabetes confirmed

Researchers at Joslin Diabetes Center have investigated PKC-beta - a critical enzyme implicated in the devastating complications of type 1 and type 2 diabetes - for more than two decades.

Experts call for more research into treatments for children's brain tumours

More independent study is needed into the biology of children's brain tumours if effective treatments are to be developed, experts at The University of Nottingham have said in a leading journal.

Low birth weight - another risk factor for diabetes

Obesity, physical inactivity, genetics and age have long been recognized as risk factors for developing high blood glucose and diabetes. But over the past few years, scientists have discovered another risk - low birth weight.

Link between hyperglycemia (high blood glucose), overexpression of PKC-beta 2 and kidney disease

Scientists at Joslin Diabetes Center have investigated PKC-beta -- a critical enzyme implicated in the devastating complications of type 1 and type 2 diabetes -- for more than two decades.

If a dividing cell's activity is a pop song, then the same process in an immune cell is an extended-play dance remix

The basics of cell division are the same in both, but there's a heck of a lot more going on in immune cells, Johns Hopkins scientists have discovered.

First clues as to why stem cells ignore stop signs in the cell cycle

Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point where other cells stop dividing.

Finding could provide targets for diagnosis, prognosis, therapy of prostate cancer

Researchers led by Dr. Shiv Srivastava from the Center for Prostate Disease Research (CPDR), Uniformed Services University of the Health Sciences (USU), report the groundbreaking discovery of the ETS-Related Gene (ERG) as one of the frequent proto-oncogene overexpressions in prostate cancer cells.

Researchers use RNAi libraries to identify regulators of apoptosis and chemoresistance

Using targeted RNA interference, or RNAi libraries, researchers at Harvard Medical School describe the first large-scale classification of kinase and phosphatase gene families on the basis of their role in apoptosis and cell survival. This study appears in the June issue of Nature Cell Biology.

DNA discovery may help explain disorders such as autism

Researchers have made a discovery that may in future help to explain many aspects of human social behavior and disorders such as autism.

Experimental drug works best in combination with older remedy for Alzheimer's disease and other dementias

An experimental drug combined with an already-popular memory-enhancing compound may further delay memory loss in patients with Alzheimer's disease and other dementias, Johns Hopkins University scientists, in collaboration with researchers from University of North Carolina, have found.

Variations in genetic code affect social behavior

Why are some people shy while others are outgoing? A study in the current issue of Science demonstrates for the first time that social behavior may be shaped by differences in the length of seemingly non-functional DNA, sometimes referred to as junk DNA.

Accumulation of genetic changes is not solely determined by natural selection

New data suggest that the accumulation of genetic changes is not solely determined by natural selection. A study by University of Chicago researchers contradicts conventional theory by showing that the percentage of mutations accepted in evolution is also strongly swayed by the speed at which new mutations arrive at a gene: the faster the speed of new mutations, the greater the percentage of those mutations accepted.

Study of glial cells in the roundworm C. elegans may provide insight into a variety of human brain diseases

The key to understanding our brains may lie within a one-millimeter long worm, new research from Rockefeller University indicates. Reporting in the June issue of Developmental Cell, Shai Shaham, Ph.D., and graduate student Elliot Perens use the roundworm, C. elegans, to investigate the mysterious glial cell, which makes up 90 percent of the human brain and, when it malfunctions, can contribute to diseases like Parkinson's disease and schizophrenia.

Exposing SMA-affected cells to aminoglycoside drugs can increase SMN

MDA grantee Christian Lorson at the University of Missouri was on a team that found that exposing cells carrying a mutation that causes spinal muscular atrophy (SMA) to drugs in the aminoglycoside family helps them produce more of the needed SMN protein, a lack of which leads to SMA.

MicroRNAs play an important role in human cancer

Over the past few years, scientists have discovered that a new class of genetic regulators called "microRNAs" influences normal human growth and development. Now, researchers have found that microRNAs also play an important role in human cancer. The findings are published in today's issue of the journal Nature (June 9).

New study shows tiny RNAs intimately associated with cancer

In discoveries that may open a new chapter in understanding and diagnosing cancer, Howard Hughes Medical Institute (HHMI) investigators and their colleagues have established that tiny microRNAs provide a novel genetic route to the initiation of some forms of cancer.
