CRISPR/Cas9 gene editing technique could be controlled using RNA-based drugs

In just the past few years, researchers have found a way to use a naturally occurring bacterial system known as CRISPR/Cas9 to inactivate or correct specific genes in any organism. CRISPR/Cas9 gene editing activity runs continuously, though, leading to risk of additional editing at unwanted sites.

Researchers suggest ways to make TB drugs more efficacious against mutations

Biophysicists have discovered why the bacteria that cause tuberculosis (TB) are naturally somewhat resistant to antibiotics known as fluoroquinolones. Their findings, based on mapping the detailed three-dimensional structure of the drugs interacting with an essential enzyme in the TB germ, also reveal why some TB drugs are more potent than others and suggest how drug developers can make fluoroquinolones more efficacious against mutations that make the lung disease drug resistant.

Johns Hopkins study shows high doses of cocaine kill brain cells

Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.

Researchers identify protein structure linked to pain and heat perception

Touch a hot stove, and your fingers will recoil in pain because your skin carries tiny temperature sensors that detect heat and send a message to your brain saying, "Ouch! That's hot! Let go!"

Combination of PARP inhibitors and c-MET may benefit breast cancer patients

Findings from a new study reveal that PARP inhibitors, an emerging class of drugs being studied in cancer clinical trials, may be enhanced by combining them with inhibitors targeting an oncogene known as c-MET which is overexpressed in many cancers.

NIST researchers simulate new method for fast, precise DNA sequencing

Researchers at the National Institute of Standards and Technology (NIST) have simulated a new concept for rapid, accurate gene sequencing by pulling a DNA molecule through a tiny, chemically activated hole in graphene--an ultrathin sheet of carbon atoms--and detecting changes in electrical current.

UM SOM selected to work with BARDA to develop radiologic and nuclear countermeasures

University of Maryland School of Medicine Department of Radiation Oncology Chair and Professor William F. Regine, MD, FACR, FACRO, and UM SOM Dean E. Albert Reece, MD, PhD, MBA, announced today that researchers at the UM SOM have been selected as key contractors by the Biomedical Advanced Research and Development Authority, for its Radiation Nuclear Animal Model Development program.

UConn-led researchers identify specific gene linked to Hajdu-Cheney syndrome

Fragile bones are usually an old person's affliction, but sometimes children are born with them. Now, a team of researchers led by UConn professor Ernesto Canalis has shown in mice that a specific gene can cause the disease, called Hajdu-Cheney syndrome. Overabundant bone-absorbing cells may be causing the disorder's characteristic bone loss, and the researchers hope to find a potential treatment.

UT Southwestern pediatric researchers identify key trigger of neonatal lung disease

Pediatric researchers at UT Southwestern Medical Center have identified a key component of the pathogenesis of bronchopulmonary dysplasia (BPD), a devastating and sometimes fatal lung disease that affects premature infants. Their findings clarify what prompts the inflammatory response that results in BPD, which previously had been unclear.

Researchers reveal biological connection between obesity and colorectal cancer risk

Obesity has long been associated with increased risk of colorectal cancer, but the link has never been understood. Now, a research team led by investigators at Thomas Jefferson University has revealed the biological connection, and in the process, has identified an approved drug that might prevent development of the cancer.
