Replacing Large Mouse Gene Regions with Human DNA

Humanized mouse models are essential for investigating human gene function; however, the complete replacement of mouse genes with entire human sequences has posed significant technical challenges.

USU Researchers Discover CRISPR Cas12a3's Potential for Viral Protein Inhibition

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to disable and modify genes, heading off infections at the (cellular) pass.

LINE-1 Retrotransposons Reshape Cancer Genome Architecture

Scientists at St. Jude Children's Research Hospital have revealed previously unappreciated roles for the retrotransposon LINE-1 in shaping the cancer genome structure and regulation.

CRISPR Reveals Dark Genome Regions That Sense Cellular Mechanics

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the 'dark genome' that are responsible for controlling how cells sense and respond to the mechanical properties of their local environment.

Heterosis in Crops Explained Through Complex Gene Interaction Analysis

When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents.

Nearly 1/3 of Pesticides and Industrial Chemicals Harm Gut Bacteria

A study reveals that common pesticides and industrial chemicals inhibit gut bacteria, highlighting risks to health and the need for revised safety assessments.

Novel Mechanism for Epigenetic Patterning in Plants

Every cell within an organism shares an identical genetic blueprint. Their distinct identities stem from epigenetics—precise chemical markers that dictate gene expression.

Human Pangenome Research Opens a New Chapter in Precision Medicine

In May 2023, the Human Pangenome Reference Consortium (HPRC) released the first draft of the human pangenome reference sequence, which integrated genomic data from 47 individuals representing genetic diversity and added 119 million base pairs of euchromatic polymorphic sequences.

Discovery of a 3D Genomic Loop Boosts Yield and Sustainability in Rice Cultivation

A team of Chinese scientists has uncovered a hidden 3D structure in rice DNA that allows the crop to grow more grain while using less nitrogen fertilizer.

Fruit Fly Study Reveals New Details on Alzheimer's Disease Risk Genes

Scientists have identified hundreds of genes that may increase the risk of developing Alzheimer's disease but the roles these genes play in the brain are poorly understood.

Reversible Epigenetic Switches Influence Memory Formation

Our experiences leave traces in the brain, stored in small groups of cells called "engrams". Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes them very interesting to research on memory and age- or trauma-related memory loss.
