A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

CRISPR Technologies Transform On-Site Detection of Animal Pathogens

The rapid spread of animal diseases and pathogen evolution have long posed significant threats to the healthy development of animal husbandry.

Bird flu withstands human fever

Avian influenza viruses pose a specific risk to people, as they can multiply at temperatures exceeding a normal fever, which is a defense mechanism used by the body to halt viruses, according to new research conducted by Cambridge and Glasgow universities.

New Regulatory Pathway Enhances Key Aroma Compound in Wine Grapes

β-Damascenone is a key norisoprenoid compound responsible for characteristic floral and fruity aromas in grapes and wines, particularly those from non-aromatic varieties such as Cabernet Sauvignon and Merlot.

Gene Transcription Start Sites Identified as Hidden Mutational Hotspots

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease.

UBQLN2 Liquid Droplets Found to Catalyze Early α-Synuclein Aggregation

Parkinson's disease (PD) is an age-related, progressive neurodegenerative disorder. The hallmark of PD pathogenesis is the Lewy bodies (LBs) that accumulate in neurons in the substantia nigra region of the brain, damaging these neurons and leading to the motor symptoms of the disease. α-synuclein (α-syn), a misfolded protein, aggregates and forms fibrils, which leads to the formation of LBs.

Scientists Uncover Inner Workings of Biomolecular Condensates Linked to ALS

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which carry out instructions from our DNA-that a living being needs.

Scientists Map How Transcription Factors Interpret DNA Sequences

With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to increased knowledge about gene regulation in human cells.

DNA Rigidity Inside the Nucleosome Regulates INO80 Positioning

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the nucleosome regulates the positioning of INO80. This highlights that the physical structure and shape of DNA, not just genetic information, are key components of DNA transcription.

Discovery Reveals Unexpected Role for OTULIN in Controlling Tau Expression

Scientists have uncovered a surprising mechanism by which a brain enzyme called OTULIN controls the expression of tau, the protein that forms toxic tangles in Alzheimer's disease.

Scientists Reveal How Memory T Cells Persist Across the Body

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again.

Old Blood Stem Cells Regain Regenerative Capacity Through Lysosomal Intervention

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes.

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.

Genetic Analysis Uncovers Six Distinct Lineages of Global Tea Germplasm

Using 150 single-nucleotide polymorphism (SNP) markers across 252 tea accessions from India and China, researchers identified six major genetic groups, including the small-leafed sinensis and five broadleaf assamica populations from India, Indochina, and Yunnan. The

New Tool Maps Microbial Activity to Transform Gut Health Research

The gut microbiome is made up of trillions of microbes that play a vital role in keeping us healthy.  A disturbance in the balance of these microbes can contribute to a variety of health conditions, such as inflammatory bowel disease (IBD).

New Polygenic Risk Scores Transform Disease Prediction for Han Chinese Populations

Researchers at Academia Sinica have developed the first population-specific polygenic risk score (PRS) models for people of Han Chinese ancestry, achieving unprecedented accuracy in predicting risks for common diseases such as diabetes, heart disease, autoimmune disorders.
