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.

A New Non-Destructive Tool Maps Active Transcription Profiles in Living Tissue

Cell function is determined by how DNA is expressed into proteins. That process includes two main steps - transcription, when messenger RNA (mRNA) makes copies of active genes, and translation, when mRNA guides protein assembly.

New Molecular Map Traces Human Disease Genes Back to LECA

A University of Texas at Austin-led team has reconstructed the most detailed map to date of the molecular machines that carried out the functions of life in an ancient ancestor that gave rise to all complex life on Earth, including us, shedding new light on genetic causes of human diseases.

Molecular Blueprint Shows How Vital Gene Regulation Complexes Form

While scientists have known for over two decades that all cells use a strategy called RNA interference to regulate gene expression, a new study is the first to describe how a specific protein manages the step-by-step process of assembling the molecular complex that performs the regulatory job.

Cells Sense Abnormal RNA Patterns to Silence Jumping Genes

Transposons, DNA sequences that can self-replicate and move (jump) throughout the genome, are widespread and can affect cell survival if left unchecked. Cells control these "jumping genes" by silencing them, but little was known about how cells recognize and defend themselves from invading transposons.

Ovarian Cancer Fluid Helps Tumors Evade Cell Death

Ascites in ovarian cancer rewires tumor metabolism, protecting cells from ferroptosis and promoting metastasis, revealing potential therapeutic targets.

Researchers Link Brain Extracellular Matrix Deterioration to Postmenopausal Memory Loss

A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.

Scientists Reconstruct a 700-Million-Year Evolutionary Tree of Blood Cells

Almost all animal species -- including humans -- have blood cells, but between different species our blood tells different stories. The lineage and components of blood cells vary widely, and this variety is a testament to how animals have evolved to protect themselves from infectious diseases.
