Senescent Fibroblasts in the Tumor Niche Rewire Lung Cancer Metabolism and Plasticity

Senescent fibroblasts are aging cells that no longer divide and protect against tumor development. Yet two decades have gone by since cell biologist Judith Campisi, PhD, paradoxically demonstrated that these same cells can promote cancer growth in a laboratory setting.

Epigenetic Signatures Explain How Andean Highlanders Thrive in Low Oxygen

DNA sequencing technology makes it possible to explore the genome to learn how humans adapted to live in a wide range of environments.

Study Reveals How Cells Compensate for Missing Chromosomes

A hallmark of cancerous cells is an abnormal number of chromosomes or chromosome arms, known as aneuploidy.

Study Reveals ATM-Driven Mechanism Behind Telomere-Induced Senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

Ambiguous Stop Codons Expand the Genetic Code in Archaea

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids to make a protein.

How Singing Mice Reveal the Roots of Vocal Communication

All mice squeak, but only some sing. Scotinomys teguina, aka Alston's singing mice, hail from the cloud forests of Costa Rica. More than 2,000 miles north, Cold Spring Harbor Laboratory (CSHL) neuroscientists study these musically gifted mammals to better understand the evolutionary origins of vocal communication.

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.

Capturing a Self-Splicing Ribozyme in Motion

RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure.

Real-Time Visualization Reveals the Transcriptional Gearbox

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins.

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.

Breakthrough Reveals How Immune Cells Orchestrate Pathological Scarring

Researchers at the University of Arizona uncovered a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue that can lead to organ failure and disfigurement.

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.

Researchers Develop High-Throughput Technique to Decode T-Cell Receptors

Studying T cells, the immune cells most responsible for responding to infections and cancers, just received a significant boost in the form of a new technique from St. Jude Children's Research Hospital.

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.

New Technique Reveals Synaptic Vesicle Dynamics in Living Brain Tissue

Researchers at Johns Hopkins Medicine say they have used a "zap-and-freeze" technology to watch hard-to-see brain cell communications in living brain tissue from mice and humans.

Senescent Blood Vessel Cells Drive the Development of Metabolic Disorders

Investigators from the Center for Advanced Gerotherapeutics at Cedars-Sinai found that aged blood vessel cells play a key role in the development of metabolic disorders, including diabetes.

Optogenetic Tool Uncovers Key Role of Mechanical Forces in Early Embryonic Development

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

New Multi-Target CAR-T Cells Eradicate Glioblastoma in Preclinical Models

With a five-year survival rate of less than 5%, glioblastoma is one of the most aggressive types of brain cancer.
