Stroke drug improves stem cell therapy in rat spinal cord injury models

Four months after treating them, Yasuhiro Shiga, MD, PhD, checked on his rats. Walking into the lab, he carried minimal expectations.

Extrachromosomal circular DNA can contribute to cancer development in children

Cancer development is associated with the gradual accumulation of DNA defects over time. Thus, cancer is considered an age-related disease.

New gene therapy has potential to reverse disease processes

Scientists have developed a new gene-therapy technique by transforming human cells into mass producers of tiny nano-sized particles full of genetic material that has the potential to reverse disease processes.

Research finds key reason why brain connectivity goes awry in rare neurodevelopmental conditions

Axons are the long thread-like extensions of neurons that send electrical signals to other brain cells. Thanks to axonal connectivity, our brains and bodies can do all necessary tasks.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Tackling antibiotic resistance head-on with CRISPR

With modern advances in genetic engineering occurring almost every day, the latest discovery concerns antibiotic resistance. Using the powerful gene editor CRISPR, scientists reported the development of a gene-drive system that is 100 times as efficient as other current systems at inactivating a specific bacterial gene responsible for making the bacterium antibiotic-resistant and which is present as multiple copies within the same bacterial cell.

Evolutionarily novel genes found to be expressed in tumors

A team of scientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) studied the evolutionary ages of human genes and identified a new class of them expressed in tumors -- tumor specifically expressed, evolutionarily novel (TSEEN) genes.

Cancer patients in Southern Italy have higher concentration of toxic metals in their blood

Toxic environmental agents, to which anyone is involuntarily exposed, represent non-negligible risk for human health and, therefore, environmental contamination has become a theme of primary importance worldwide.

Researchers identify rare genetic disorder

A team of South Australian researchers has cracked a rare gene variant for a disorder that sees a normal healthy child start to lose muscle tone and motor skills, ultimately losing the capacity to walk and use language.

New gene technology shows 100-fold efficiency in targeting antibiotic-resistant bacteria

Taking advantage of powerful advances in CRISPR gene editing, scientists at the University of California San Diego have set their sights on one of society's most formidable threats to human health.

The evidence for BRCA1/2 or any genetic testing in breast cancer patients

A new statement by the American College of Medical Genetics and Genomics (ACMG), published in the journal Genetics in Medicine, discusses the place of germline genetic testing in breast cancer patients.

Study shows non-TB lung infections rising; more in women and older people

Each year, more and more people are getting mycobacterial lung infections, and the total number living with such diseases is going up, according to a new study published in the journal Annals of the American Thoracic Society. Those at greatest risk are people above the age of 65 years and the elderly.

Using new high-resolution imaging to track titin in real time

Using new high-resolution imaging techniques, MDC researchers and colleagues have tracked titin, the body's largest protein, in real time throughout its entire lifecycle. The method and results could provide new insight into muscle development as well as treating damaged muscles and heart disease.

Study unveils new layers of mystery about visual memory, amblyopia

In decades of studying how neural circuits in the brain's visual cortex adapt to experience, MIT Professor Mark Bear's lab has followed the science wherever it has led, yielding the discovery of cellular mechanisms serving visual recognition memory, in which the brain learns what sights are familiar so it can focus on what's new, and of a potential therapy for amblyopia, a disorder where children born with disrupted vision in one eye can lose visual acuity there permanently without intervention.

International project to preserve genetic resources of birds

The support is provided by the Russian Foundation for Basic Research and the Science and Innovation in East Asia Consortium. Kazan Federal University's partners are Mahidol University and Kumamoto University.

Molecular subtyping of bladder tumors outperformed by standard pathology tests

While trying to develop a comparatively easy, inexpensive way to give physicians and their patients with bladder cancer a better idea of likely outcome and best treatment options, scientists found that sophisticated new subtyping techniques designed to do this provide no better information than long-standing pathology tests.

Novel drug shows efficacy against advanced ROS1 and NTRK fusion-positive NSCLC

Pooled analysis of three phase 1 and 2 clinical trials published online ahead of print in the journal Lancet Oncology show that the drug entrectinib is effective and well-tolerated against advanced ROS1 and NTRK fusion-positive non-small cell lung cancers (NSCLC).

Community-based program enables donation of tumor tissue and blood samples for research

Precision medicine with targeted therapies has led to improved treatment options and patient outcomes. These approaches were developed by studying tumors grown in laboratories and patient samples obtained before and during their treatment.

Neuroscientists develop new method for uniquely targeted gene therapy

Neuroscientists at Lund University in Sweden have developed a new technology that engineers the shell of a virus to deliver gene therapy to the exact cell type in the body that needs to be treated. The researchers believe that the new technology can be likened to dramatically accelerating evolution from millions of years to weeks.

IU researchers discover how to predict recurrence of triple negative breast cancer

Indiana University School of Medicine researchers have discovered how to predict whether triple negative breast cancer will recur, and which women are likely to remain disease-free.
