Novel gene therapy approach may treat dysferlinopathies

The challenge of treating patients with genetic disorders in which a single mutated gene is simply too large to be replaced using traditional gene therapy techniques may soon be a thing of the past. A Nationwide Children's Hospital study describes a new gene therapy approach capable of delivering full-length versions of large genes and improving skeletal muscle function. The strategy may hold new hope for treating dysferlinopathies and other muscular dystrophies.

Researchers describe inflammatory mechanism of sunburn

The biological mechanism of sunburn - the reddish, painful, protective immune response from ultraviolet (UV) radiation - is a consequence of RNA damage to skin cells, report researchers at the University of California, San Diego School of Medicine and elsewhere in the July 8, 2012 Advance Online Publication of Nature Medicine.

DNA from CF patients with and without chronic infections points to unsuspected mutation

Comparing the DNA from patients at the best and worst extremes of a health condition can reveal genes for resistance and susceptibly. This approach discovered rare variations in the DCTN4 gene among cystic fibrosis patients most prone to early, chronic airway infections.

High expression of interleukin-9 in immune cells inhibits melanoma growth

Researchers from Brigham and Women's Hospital (BWH) have made a groundbreaking discovery that will shape the future of melanoma therapy. The team, led by Thomas S. Kupper, MD, chair of the BWH Department of Dermatology, and Rahul Purwar, PhD, found that high expression of a cell-signaling molecule, known as interleukin-9, in immune cells inhibits melanoma growth.

Conference highlights utility of zebrafish for human disorder studies

Zebrafish, popular as aquarium fish, now have an important place in research labs as a model organism for studying human diseases.

Effect of spaceflight on C. elegans could help it to live longer

The effect of spaceflight on a microscopic worm - Caenorhabditis elegans (C. elegans) - could help it to live longer.

New epigenetic path toward a cure for osteoarthritis

In what could be a breakthrough in the practical application of epigenetic science, U.K. scientists used human tissue samples to discover that those with osteoarthritis have a signature epigenetic change (DNA methylation) responsible for switching on and off a gene that produces a destructive enzyme called MMP13.

New insights into role and importance of exosomes and their targeted gene transcripts

In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

PHF21A gene plays a big role in Potocki-Shaffer syndrome

A gene whose mutation results in malformed faces and skulls as well as mental retardation has been found by scientists.

MiR-125b downregulated in both aggressive and indolent forms of CLL

Loss of a particular microRNA in chronic lymphocytic leukemia shuts down normal cell metabolism and turns up alternative mechanisms that enable cancer cells to produce the energy and build the molecules they need to proliferate and invade neighboring tissue.

Reprogramming asthma-promoting immune cells diminishes airway damage and inflammation

Reprogramming asthma-promoting immune cells in mice diminishes airway damage and inflammation, and could potentially lead to new treatments for people with asthma, researchers have found.

Study shows cells from different Parkinson’s patients have unique drug responses

Researchers have taken a step toward personalized medicine for Parkinson's disease, by investigating signs of the disease in patient-derived cells and testing how the cells respond to drug treatments.

Neighboring non-cancer cells may contribute to drug resistance

One of cancer's most frightening characteristics is its ability to return after treatment. In the case of many forms of cancer, including the skin cancer known as melanoma, tailored drugs can eradicate cancer cells in the lab, but often produce only partial, temporary responses in patients. One of the burning questions in the field of cancer research has been and remains: how does cancer evade drug treatment?

The Jeffrey Epstein VI Foundation supports Genetic Initiative at CCFA

The Jeffrey Epstein VI Foundation, which actively supports science research, has given substantial support to the Crohn's and Colitis Foundation of America to continue its Genetic Initiative to find a cure for the diseases.

Study examines how cells exploit gene sequences to cope with toxic stress

Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.

Epigenetic changes due to methylation play a key role in altering genes in RA

It's not just our DNA that makes us susceptible to disease and influences its impact and outcome. Scientists are beginning to realize more and more that important changes in genes that are unrelated to changes in the DNA sequence itself - a field of study known as epigenetics - are equally influential.

Important insight into association between childhood maltreatment and suicide

Exposure to childhood maltreatment increases the risk for most psychiatric disorders as well as many negative consequences of these conditions. This new study, by Dr. Gustavo Turecki and colleagues at McGill University, Canada, provides important insight into one of the most extreme outcomes, suicide.

Scientists reprogram amniotic fluid cells without introduction of extra genes

Stem cells found in amniotic fluid can be transformed into a more versatile state similar to embryonic stem cells, according to a study published today in the journal Molecular Therapy. Scientists from Imperial College London and the UCL Institute of Child Health succeeded in reprogramming amniotic fluid cells without having to introduce extra genes.

Cigarette smoke reduces production of Fallopian tube gene - BAD

Cigarette smoke reduces the production of a Fallopian tube gene known as "BAD", which helps explain the link between smoking and ectopic pregnancy. The finding, from scientists led by Drs Andrew Horne and Colin Duncan at the Medical Research Council (MRC) Centre for Reproductive Health in Edinburgh, UK, was described today at the annual meting of ESHRE (European Society of Human Reproduction and Embryology) in Istanbul.
