New "Ultra-Mild" Method Corrects Cancer DNA Methylation Test Errors

Traditional bisulfite sequencing damages DNA, while enzyme-based alternatives are inconsistent. A novel methylation analysis method, called UMBS-seq, was published this week in Nature Communications. UMBS-seq achieves both accuracy and gentleness, unlocking more reliable cancer biomarker detection.

RNA Molecules Alter Genome Structure to Silence Critical Neuronal Genes During Stress

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

Scientists Uncover How "P Bodies" Guide Stem Cells to Their Destinies

How do stem cells know what to become? Nearly three decades after scientists isolated the first human embryonic stem cells, researchers are still working hard to understand precisely how a single, undifferentiated cell can become any one of the roughly 200 cell types that make up the human body.

Weill Cornell Scientists Develop Safe and Precise Tool to Control Gene Activity

Investigators at Weill Cornell Medicine have developed a versatile and non-toxic technology for controlling the activity of any gene in a cell. Such "gene-switch" tools allow scientists to "turn on" or "turn off" a target gene to study how it works, model diseases and design new therapies.

Study Unveils the Complete Biosynthetic Loop Regulating Tannin Production in Strawberries

Hydrolyzable tannins (HTs), including gallotannins and ellagitannins, are essential polyphenolic compounds that influence fruit taste, antioxidant capacity, and stress tolerance. Although condensed tannin biosynthesis has been well studied, the enzymatic processes governing HT formation remain unclear.
