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.

PLAMseq Revolutionizes Simultaneous Analysis of Genome Proteins and Their Locations

A team from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) has developed an innovative technique called PLAMseq (proximity-labelled affinity-purified mass spectrometry plus sequencing) that, for the first time, allows simultaneous analysis of chromatin-associated proteins and their location in the genome in a single experiment.

New Tool Predicts Which Intrinsically Disordered Regions Drive Condensate Formation

Fusion oncoproteins arise when a gene fuses with another gene and acquires new abilities. Such abilities can include the formation of biomolecular condensates, "droplets" of concentrated proteins, DNA or RNA.

Study Uncovers Principles Guiding Replication Initiation Across the Human Genome

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, and genetic disorders.

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.

New Evidence Shows Complex Life Began Far Earlier Than Previously Believed

Complex life began to develop earlier, and over a longer span of time, than previously believed, a groundbreaking new study has revealed.

Single-Cell RNA Imaging Uncovers Four Distinct Neuron Bands in the Hippocampus

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have identified a previously unknown pattern of organization in one of the brain's most important areas for learning and memory.

New Label-Free Breakthrough for Studying Bacterial Shape Diversity

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can't be grown in the lab.

Unraveling How GFAP Mutations Disrupt Mitochondria in Alexander Disease

Some brain disorders are straightforward, such as the direct frontal lobe assault of a concussion or traumatic brain injury. Others, like Alexander disease, are akin to guerilla warfare.

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.
