Insight into reasons why precocious puberty occurs in females

New research from Oregon Health & Science University has provided significant insight into the reasons why early-onset puberty occurs in females.

ADRB receptors play a direct role in Src activation by PKA-mediated mechanism

Scientists at The University of Texas MD Anderson Cancer Center have discovered the signaling pathway whereby a master regulator of cancer cell proteins - known as Src - leads to ovarian cancer progression when exposed to stress hormones. The researchers report in the current issue of Nature Communications that beta blocker drugs mitigate this effect and reduce cancer deaths by an average of 17 percent.

FBH1 gene helps turn up the effect of chemotherapy

Chemotherapy is one of the most common treatments for cancer patients. However, many patients suffer from serious side-effects and a large proportion does not respond to the treatment. Researchers from the Biotech Research and Innovation Centre (BRIC) and Center for Healthy Aging, University of Copenhagen, now show that the gene FBH1 helps turn up the effect of chemotherapy.

Phenformin decreases size of lung tumors and increases survival in mice

Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, Reuben Shaw has wondered if drugs originally designed to treat metabolic diseases could also work against cancer.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

One-step, off-the-shelf tool can help evaluate genetic cause of mitochondrial diseases

More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA—within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases.

U-M researchers develop new method thet could enhance gene sequencing data

When researchers sequence the RNA of cancer cells, they can compare it to normal cells and see where there is more RNA. That can help lead them to the gene or protein that might be triggering the cancer.

Study examines how fear responses are learned, controlled and memorized

A rustle of undergrowth in the outback: it's a sound that might make an animal or person stop sharply and be still, in the anticipation of a predator. That "freezing" is part of the fear response, a reaction to a stimulus in the environment and part of the brain's determination of whether to be afraid of it.

Scientists identify genetic process in which normal liver cells transform into cancerous ones

A team of scientists from the Cancer Science Institute of Singapore (CSI) at the National University of Singapore (NUS) has identified a genetic process in which normal liver cells transform into cancerous ones. The finding provides new understanding into the pathogenesis of human cancers.

Oncolytics Biotech reports new findings at ASCO’s 2013 Gastrointestinal Cancers Symposium

What did Pope John Paul II, Ronald Reagan and Robin Gibb of the Bee Gees have in common? Each was diagnosed with colorectal cancer, the third most commonly diagnosed cancer in the world and the fourth most common cause of cancer death.

Scientists discover four processes by which gastric cancer is formed

Scientists at A*STAR's Genome Institute of Singapore (GIS) headed a study that discovered four processes by which gastric cancer is formed. This is extremely important since gastric cancer is the second most common cause of cancer deaths worldwide, claiming almost 750,000 lives annually, 60% of which are Asians.

Mutated Nesprin4 protein prevents hearing

Because half of all instances of hearing loss are linked to genetic mutations, advanced gene research is an invaluable tool for uncovering causes of deafness - and one of the biggest hopes for the development of new therapies. Now Prof. Karen Avraham of the Sackler Faculty of Medicine at Tel Aviv University has discovered a significant mutation in a LINC family protein - part of the cells of the inner ear - that could lead to new treatments for hearing disorders.

Women with BRCA gene mutations tend to undergo menopause sooner than others

Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a study led by researchers at UC San Francisco.

Reprogramming eye cells that enable night vision may one day treat retinitis pigmentosa

Doctors may one day treat some forms of blindness by altering the genetic program of the light-sensing cells of the eye, according to scientists at Washington University School of Medicine in St. Louis.

DRCRF announces recipients of Nov. 2012 Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 15 new Damon Runyon Fellows at its fall Fellowship Award Committee review.

Five genes hold key to meningioma make up

Research published in Science shows that mutations in five genes characterize most meningiomas.

Temple scientists to solve long-standing mystery in sepsis

Scientists at the Center for Translational Medicine at the Temple University School of Medicine are inching closer to solving a long-standing mystery in sepsis, a complex and often life-threatening condition that affects more than 400,000 people in the U.S. every year.

The LINC complex essential for hearing

In this issue of the Journal of Clinical Investigation, Karen Avraham and colleagues at Tel Aviv University identified a genetic mutation in two families with hereditary high frequency hearing loss. The mutated gene, which has not previously been linked to hearing loss, encodes NESP4, a protein that is expressed in the outer nuclear membrane (ONM) of the hair cells of the ear.

Alzheimer's Association, SNMMI publish appropriate use criteria for brain amyloid imaging with PET

Only recently has it become possible to create high-quality images of the brain plaques characteristic of Alzheimer's disease in living people through positron emission tomography (PET). Even so, questions remain about what can be learned from these PET images and which people should have this test.
