Changes in the activity of gene networks may explain arteriosclerosis risk

Up to 60 percent of the risk associated with coronary arteriosclerosis may be explained by changes in the activity of hundreds of genes working together in networks across several organs in the body.

Researchers conduct genome sequencing studies in children with in-born immunity disorders

The Sanford Children’s Genomic Medicine Consortium has ten hospitals collaborating for whole genome sequencing studies on patients with suspected inborn immunity disorders (IEI).

Researchers map the cellular landscape in diabetic foot ulcers

Diabetic foot ulcerations – open sores or wounds that refuse to heal – are a devastating complication affecting more than 15 percent of people with diabetes and resulting in more than 70,000 lower extremity amputations per year in the United States alone.

Research explains how E4 peptide exerts antifibrotic effect and what makes it so effective

A research team at the Medical University of South Carolina led by Carol Feghali-Bostwick, Ph.D., reports in the Journal of Clinical Investigation Insight that the E4 peptide reverses fibrosis, or scarring, in human and mouse tissues by activating an antifibrotic pathway that is common to all organ systems.

Omicron variant hampers the effectiveness of vaccines and monoclonal antibodies, study shows

The Omicron variant was detected for the first time in South Africa in November 2021 and has since spread to many countries.

Experts introduce new gene therapy approach for muscle weakness

Experts at Children’s National Hospital have created a new pre-clinical gene therapy for the rare condition limb-girdle muscular dystrophy (LGMD) 2B.

Novel delivery system for genome editing in vascular endothelial cells developed

The laboratory of Youyang Zhao developed a novel nanoparticle to deliver genome editing technology, such as CRISPR/Cas9, to endothelial cells, which line blood vessel walls.

New model system reveals how tiny bacteria from the environment have adapted to live inside humans

The microbes that live inside our mouths, collectively known as the oral microbiome, impact our overall health in many ways that are not yet fully understood.

Olfactory receptor gene may drive breast cancer metastasis to the brain

An olfactory receptor gene that aids in the sense of smell may also play a role in the metastasis of breast cancer to the brain, bones and lung, researchers from Massachusetts General Hospital have found.

Cryobioprinting uses a bioink embedded with cells to print frozen and complex structures

A new technique takes bioprinting -; in which an ink of cells is printed, layer by layer, to form a structure -; to a whole new, and icy level. Investigators from the Zhang lab at Brigham and Women's Hospital have developed a technology that they term "cryobioprinting," a method that uses a bioink embedded with cells to print frozen, complex structures that can be easily stored for later use.

Severe lung injuries can trigger stem cells to undergo abnormal differentiation, study finds

Severe injuries to the lung from diseases such as COVID-19 trigger abnormal stem cell repair that alters the architecture of the lung. The aberrant stem cell differentiation in response to injury can prevent the restoration of normal lung function.

COVID-19 virus spreads through cell-to-cell transmission

The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found.

Study identifies two proteins as novel markers of aggressive prostate cancer

Prostate cancer is the most commonly diagnosed cancer in men and is among the top five causes of cancer-related death. In most cases, prostate cancer can be successfully treated but there is a group of patients who suffer an aggressive course and often fatal outcome.

Experts carry out the first major genetic study into cortical folding patterns

The brain’s surface, the cortex, is folded into an intricate pattern of grooves (sulci) and bumps (gyri). Individual differences in this pattern are associated with cognitive performance and brain disorders, however very little is known on how the “bumpiness and grooviness” of the cortex is determined.

Genetic mutation appears to be a predisposing factor for COPD independent of smoking

In 2019, the WHO positioned chronic obstructive pulmonary disease (COPD) third in the global ranking of causes of death.

Detecting high-impact rare genetic variants in individuals with severe schizophrenia

New research published in the Proceedings of the National Academy of Sciences shows that examining genetic mutations in individuals with severe schizophrenia can improve the ability to detect disease-associated rare genetic variants.

Study details the design of RNA-based breathalyzer to diagnose SARS-CoV-2

In a new study in The Journal of Molecular Diagnostics, published by Elsevier, investigators report on the design and testing of a breathalyzer, known as the Bubbler, that relies on viral RNA detection to diagnose SARS-CoV-2. Its name is derived from the bubbling sound that occurs when the patient exhales into the device.

Scientists find how cells remain dormant for years before awakening to create metastatic cancer

Mount Sinai researchers have solved a major mystery in cancer research: How cancer cells remain dormant for years after they leave a tumor and travel to other parts of the body, before awakening to create metastatic cancer.
