Genetic mutation may accelerate heart function decline in DMD patients

A mutation in the gene that causes cystic fibrosis may accelerate heart function decline in those with Duchenne muscular dystrophy (DMD), a new study by UT Southwestern researchers suggests.

Researchers investigate the effect of palm oil extract on mice liver cells

Palm oil contains abundant quantities of vitamin E compounds, which include tocopherols and tocotrienols.These compounds have anti-oxidant effects, which protect cells from damage from toxic chemical produced by metabolic processes.

Researchers identify genetic basis for anti-neutrophil cytoplasmic antibody-associated vasculitis

Autoimmune disease is fundamentally a mystery: whyever should an organism systematically set out to harm itself?

New, effective CRISPR-based gene drive approach to control transmission of malaria parasites

Employing a strategy known as "population modification," which involves using a CRISPR-Cas9 gene drive system to introduce genes preventing parasite transmission into mosquito chromosomes, University of California researchers have made a major advance in the use of genetic technologies to control the transmission of malaria parasites.

Adaptive evolution of human coronaviruses may necessitate frequent reformulation of vaccines

Researchers from the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center, USA, have revealed that adaptive evolution in the antigenic regions facilitates seasonal coronaviruses to escape the host immune responses and to cause recurrent infections.

UConn researcher identifies genes and regulatory elements critical to heart development

The advent of genome science has given researchers an unprecedented ability to understand the root causes of a host of conditions.

Study finds new clues for disarming antibiotic-resistant bacteria

A virus can stop bacteria from sharing genes for antibiotic resistance among themselves, Texas A&M AgriLife researchers have discovered. The results hint at new ways to treat infections and describe a new feature of a highly diverse, largely unexplored part of the biosphere.

Blood vessel malformations originate in vein cells

In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells.

Researchers use sequencing data to study the key drivers of speciation, adaptation in corals

A new study led by the University of Hawai'i at Mānoa's Hawai'i Institute of Marine Biology (HIMB) revealed that diversity in Hawaiian corals is likely driven by co-evolution between the coral host, the algal symbiont, and the microbial community.

Study: 1 in 8 patients with cancer have inherited gene mutations

Genetic testing can uncover inherited genetic mutations, and could individualize cancer therapies, improve survival, manage cancer in loved ones and push the boundaries of precision medicine.

Two studies find age as a primary factor in melanoma treatment resistance

Age may cause identical cancer cells with the same mutations to behave differently. In animal and laboratory models of melanoma cells, age was a primary factor in treatment response.

Researchers develop new, improved human-skin equivalent

Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) have developed an improved human-skin equivalent that reproduces traction-force balance in the lateral direction, a property that controls the structure and physiological function of skin.

Study reveals molecular mechanism that increases the invasiveness of radioresistant cancer cells

Scientists have revealed the molecular mechanism regulating the trafficking of lysosomes that increases the invasiveness of radioresistant cancer cells following radiotherapy.

Researchers identify distinct link between autism and brain cell abnormalities

Johns Hopkins Medicine researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges platonic (non-sexual) feelings of love and sociability.

Study: Toxins produced by tube-dwelling anemones have pharmacological potential

Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals.

"Training" the immune system with β-glucan compound may improve immune recovery

Immunotherapies, such as checkpoint inhibitor drugs, have made worlds of difference for the treatment of cancer.Most clinicians and scientists understand these drugs to act on what's known as the adaptive immune system, the T cells and B cells that respond to specific threats to the body.

Scientists use new approach to analyze millions of chemical-gene interactions

A University of Massachusetts Amherst environmental health scientist has used an unprecedented objective approach to identify which molecular mechanisms in mammals are the most sensitive to chemical exposures.

SARS-CoV-2 load varies widely in the community and over time

A new study published on the preprint server medRxiv* in October 2020 reports that there are large differences in the viral load in different communities. Moreover, the authors say that the cycle threshold values required to obtain a positive result for viral RNA by polymerase chain reaction may provide an early warning of an outbreak.

Study suggests a role for the hypothalamus in genetic susceptibility to IBD

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies, researchers at Children's Hospital of Philadelphia have found significant genetic correlations between inflammatory bowel disease and stress and depression.
