Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Advances in chemistry and delivery are taking oligonucleotide medicines beyond rare diseases

A review in Cell Reports Medicine examines how advances in oligonucleotide chemistry and delivery have established ASOs and RNA interference therapies as a class of genetic medicines, with 21 oligonucleotides approved at the time of writing. It also identifies extrahepatic delivery, safety, target validation, individualized treatment, and data quality as priorities as the field expands into common diseases and explores AI-assisted development.

PsychAD studies map molecular mechanisms across major brain disorders

Research led by Mount Sinai scientists within the PsychAD Consortium, a large-scale, multidisciplinary initiative launched in 2019 with support from the National Institute on Aging (NIA), is featured in a landmark collection of nine papers published across the Nature family of journals that maps the molecular mechanisms underlying Alzheimer's disease, Parkinson's disease, schizophrenia, and other brain disorders.

Discovery of receptor-free signaling reveals better targets for treating autoimmune diseases

Our understanding of how cells interact with each other has been driven for decades by the central concept of receptor-mediated signal transduction.

Dietary changes can prevent Hirschsprung disease symptoms

A multi-institutional study led by researchers at Children's Hospital of Philadelphia (CHOP) discovered for the first time that dietary interventions might prevent inflammatory symptoms associated with Hirschsprung disease, a bowel motility disorder.

Garvan research reveals hidden inflammation behind high colon cancer risk

New research from the Garvan Institute of Medical Research has revealed for the first time that two closely related bowel diseases, currently treated in the same way, are fundamentally different.

Regular exercisers show distinct metabolic and immune signatures in blood

Researchers compared blood samples from 40 regular exercisers and 46 sedentary adults and found differences in metabolites, blood chemistry, and immune cell gene activity. The patterns suggested greater fatty acid use and altered immune signaling among exercisers, but the study could not establish that exercise caused these differences.

MIT researchers develop noninvasive way to spot aging zombie cells

As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration, and inflammatory diseases.

Adenine base editing slows neurodegeneration in hereditary motor neuron disease

A team of researchers led by Professor Haruhisa Inoue (Center for iPS Cell Research and Application, Kyoto University) and Professor Yuishin Izumi (Tokushima University) demonstrated that adenine base editing can correct a disease-causing genetic mutation and alleviate neurodegeneration in hereditary motor and sensory neuropathy with proximal dominant involvement (HMSN-P), providing proof of concept for a precision gene therapy for inherited motor neuron diseases.

Study identifies two opposing molecular patterns in autism models

Autism spectrum disorder (ASD) is associated with more than 1,200 risk genes, raising a fundamental question: Do these diverse genetic changes affect the brain in entirely different ways, or do they converge on shared biological mechanisms?

New MRI measure maps blood flow and cellular organization

Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a new, noninvasive way to examine how blood flow and cellular organization align across the layers of the living human brain.

Could a daily glass of orange juice support heart health? Study finds citrus compounds influence genes linked to blood vessel function

Naturally occurring compounds in orange juice regulated genes involved in the control of cardiovascular and blood vessel function, according to a new clinical trial.

Genetic discovery offers clues for repairing damaged neural connections

A new discovery by neuroscientists at Brown University's Carney Institute for Brain Science challenges long-held beliefs in neurobiology about how neurons extend axons to reach their targets.

Study identifies DNA loops as essential for tissue regeneration

After an injury, DNA not only alters its activity but also the way it is organized spatially within the cell nucleus.

Advanced AI cell models redefine modern cell biology research

Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell.

Study uncovers mechanism for reading extra-long neuronal genes

Neurons in humans and other mammals express many exceptionally long genes, ranging from more than 100 kb to over 2 Mb, that are important for forming synapses and neural circuits.

Giant-nucleus cells form the foundation of early-stage cancer

Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous.

Rituximab alters T-cell metabolism in patients with nephrotic syndrome

Nephrotic syndrome is caused when the filtering system in the kidneys is damaged, allowing large amounts of protein to leak into the urine.

AlphaGenome Atlas maps billions of genetic changes with AI

The human genome contains approximately 3 billion DNA letters, creating more than 9 billion possible single-letter changes.

Scientists traced a hidden immune route that may worsen tau-linked brain damage

In a mouse model of tauopathy, conventional type 1 dendritic cells (cDC1s) cross-presented brain-derived antigens in deep cervical lymph nodes, priming CD8+ T cells that accumulated in the brain and promoted neurodegeneration. Disrupting cDC1s or their cross-presentation activity reduced CD8+ T-cell infiltration and protected against neuronal loss, while human primary tauopathy samples also showed increased brain CD8+ T cells, although cDC1 involvement in humans remains unconfirmed.

Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.
