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.

Distinct transcriptomic profiles guide early development of maxillary and mandibular teeth

The interaction between genetics and tissue environment shapes how individual teeth form in different regions of the jaw.

New findings show why the human intestine uniquely presents gluten to T cells

Human intestinal M cells function as dendritic cell-like antigen-presenting cells, displaying constitutive MHC-II activity and specialized machinery for processing gluten. Their ability to deamidate and present gliadin peptides positions them as key initiators of immune responses relevant to coeliac disease.

Study reveals shared genetic roots across multiple psychiatric disorders

Distinct psychiatric disorders have more in common biologically than previously believed, according to the largest and most detailed analysis to date of how genes influence mental illness.

Shared genetic roots of 14 psychiatric disorders revealed

Researchers from the Psychiatric Genomics Consortium (PGC) report that most genetic influences on mental illness are shared across diagnostic categories, revealing a more interconnected biological landscape than traditional classifications suggest.

Disrupted genome architecture drives lymphoma development

Cancer isn't just about broken genes-it's about broken architecture. Imagine a city where roads suddenly vanish, cutting off neighborhoods from essential services.

Machine learning models can help diagnose ALS earlier from a blood sample

Using machine learning models, researchers at Michigan Medicine have identified a potential way to diagnose amyotrophic lateral sclerosis, or ALS, earlier from a blood sample, a study suggests.

Nanoflower-treated stem cells deliver healthier mitochondria to stressed cells

This study shows that vacancy-engineered MoS₂ nanoflowers drive mitochondrial biogenesis in human mesenchymal stem cells by activating SIRT1–PGC-1α signaling and reducing oxidative stress. These treated cells transfer more functional mitochondria to injured recipient cells, restoring energy metabolism and redox balance in multiple in vitro models.

Small molecule discovery could open the door to new class of treatments for hard-to-treat cancers

Researchers at the UCLA Health Jonsson Comprehensive Cancer Center have identified a small molecule that can inhibit a cancer-driving protein long considered impossible to target with drugs - a discovery that could open the door to a new class of treatments for leukemia and other hard-to-treat cancers.

Everyday PFAS exposure alters placental function in early pregnancy

This study measured real-life PFAS concentrations in first-trimester human placentas and used these data to create a pregnancy-relevant PFAS mixture. In 3D trophoblast spheroid models, the mixture altered invasion, hormone secretion, and gene expression without broadly reducing viability at environmentally relevant doses.

Timing of genetic mutation dictates childhood leukemia aggressiveness

A team of researchers at the Icahn School of Medicine at Mount Sinai has uncovered why children with the same leukemia-causing gene mutation can have dramatically different outcomes: it depends on when in development the mutation first occurs.

Early pregnancy placenta models show significant effects from PFAS exposure

Per- and polyfluoroalkyl substances (PFAS) are a group of nearly 10,000 long-lasting chemical compounds that stay in the environment and have been linked to adverse health effects on humans, including pregnant women and their unborn children.

Why soybean oil may fuel weight gain

Researchers investigate how soybean oil may disrupt fat metabolism to potentially increase the risk of obesity.

Retinal organoids provide a powerful tool to diagnose and study Leber congenital amaurosis

Leber Congenital Amaurosis (LCA) is an inherited retinal disease leading to severe vision impairment from early infancy, affecting 2-3 out of every 100,000 newborns. LCA is caused by variants in certain genes from which proteins essential for retinal cell function and survival are made.

Hidden cellular layers in the hippocampus' CA1 region revealed

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have identified a previously unknown pattern of organization in one of the brain's most important areas for learning and memory.

DNA language model performance hinges on pre-training data choices

Researchers at The University of Texas MD Anderson Cancer Center have performed a comprehensive evaluation of five artificial intelligence (AI) models trained on genomic sequences, known as DNA foundation language models.

Rice researchers develop resettable serum markers for clearer brain activity signals

Tracking how genes switch on and off in the brain is essential for understanding many neurological diseases, yet the tools to monitor this activity are often invasive or unable to capture subtler changes over time.

Common water pill may be a useful add‑on to the standard HIV treatment

An FDA‑approved medication called spironolactone, often prescribed as a diuretic, or water pill, for heart and blood pressure conditions, may be a useful add‑on to the standard HIV treatment, according to new research from the Valente lab at The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology.
