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.

23andMe identifies seven SNPs associated with breast size

Using data from its unique online research platform, 23andMe, a leading personal genetics company, has identified seven single-nucleotide polymorphisms (SNPs) significantly associated with breast size, including three SNPs also correlated with breast cancer in a genome-wide association study (GWAS) now published online in BMC Medical Genetics.

Scientists develop new animal model to study nonalcoholic steatohepatitis

Scientists at Texas Biomed have developed the laboratory opossum as a new animal model to study the most common liver disease in the nation - afflicting up to 15 million Americans - and for which there is no cure.

New method promotes selection and growth of dangerous cancer cells

The news a cancer patient most fears is that the disease has spread and become much more difficult to treat. A new method to isolate and grow the most dangerous cancer cells could enable new research into how cancer spreads and, ultimately, how to fight it.

WSU researcher looks for clues on link between H1N1 flu and obesity

The recent H1N1 flu pandemic was found to be particularly dangerous to obese people, and a Wayne State University researcher is looking for clues as to why.

Researchers use mouse model of autism to treat CTD

Using a mouse model of autism, researchers at the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center have successfully treated an autism spectrum disorder characterized by severe cognitive impairment.

Rodents may hold the key to long and active lifespan

Compared to the average three year life span of a common rat, the 10 to 30 year life of the naked mole rat, a subterranean rodent native to East Africa, is impressive. And compared to the human body, the body of this rodent shows little decline due to aging, maintaining high activity, bone health, reproductive capacity, and cognitive ability throughout its lifetime. Now a collaborative of researchers in Israel and the United States is working to uncover the secret to the small mammal's long - and active - lifespan.

NOTCH1 signaling promotes T-cell acute lymphoblastic leukemia-initiating cell regeneration

Research suggests that patients with leukemia sometimes relapse because standard chemotherapy fails to kill the self-renewing leukemia initiating cells, often referred to as cancer stem cells. In such cancers, the cells lie dormant for a time, only to later begin cloning, resulting in a return and metastasis of the disease.

Study confirms a rare susceptibility variant in glioma

Researchers at Moffitt Cancer Center working with colleagues at three other institutions have validated a link between a rare genetic variant and the risk of glioma, the most common and lethal type of brain tumor.

Researchers identify new gene target for leukemia therapy

Researchers at the University of Cincinnati (UC) Hoxworth Blood Center have discovered a new gene target for leukemia therapy.

Being a parent protects against cold: Study

Being a parent reduces your risk of catching a cold—possibly because of unknown "psychological or behavioral differences between parents and nonparents," according to a study in the July issue of Psychosomatic Medicine, the official journal of the American Psychosomatic Society.

July issue of Neurosurgery provides update on Human Connectome Project

A research effort called the Human Connectome Project is seeking to explore, define, and map the functional connections of the human brain. An update on progress in and upcoming plans for the Human Connectome Project appears in the July issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

PGD for breast cancer genes BRCA1/2 is now feasible

Preimplantation genetic diagnosis (PGD) for the breast cancer genes BRCA1/2 is now feasible and established, with good success rates for those treated, according to investigators from the reproduction, oncology and genetics centres of the university hospitals of Maastricht and Brussels.

GRP78 plays an important role in breast cancers that respond to anti-estrogen therapy

Researchers at Georgetown Lombardi Comprehensive Cancer Center have uncovered a single molecule they say is a major determinant of resistance to anti-estrogen therapy used to treat or prevent breast cancer in high-risk women.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Study identifies possible new approach to defeat bacterial infections

Research led by St. Jude Children's Research Hospital scientists has identified a possible new approach to defeating bacterial infections by targeting an innate immune system component in a bid to invigorate the immune response.

Osteoarthritis susceptibility: eight potential genes discovered

The largest genome-wide association study (GWAS) of osteoarthritis to date, published Online First in The Lancet, has uncovered eight new genetic variants or loci that appear to increase susceptibility to the most common form of arthritis, which affects about 40% of the world population older than 70 years. These findings bring the total number of osteoarthritis susceptibility genes isolated in European populations to 11.

GHB binds to GABAA-receptor in the brain under physiologically relevant conditions

Researchers are closer to understanding the biology behind GHB, a transmitter substance in the brain, best known in its synthetic form as the illegal drug fantasy. These findings have just been published in the scientific journal PNAS.
