Zipping Up Chromosomes: The Synaptonemal Complex Revealed

We have two copies of each chromosome in every cell in our bodies except in our reproductive cells. Sperm and egg cells contain a single copy of each chromosome with a unique mix of genes from our parents, an evolutionary trick to give our offspring genetic variability.

Researchers Discover How Microbes Enhance Fruit Fly Reproduction

For many of us, when we think of microbiomes, our first thoughts are probably about the beneficial microorganisms that live in our guts.

A Surprising Control Mechanism of Chlamydomonas Cell Division

Headed by James Umen, PhD, a team of international researchers at the Donald Danforth Plant Science Center has uncovered a surprising revelation about the single-celled green alga Chlamydomonas and its control over cell division.

The Exclusome, A New Mammalian "Container"

We speak to Dr. Ruth Kroschewski about new research that details the existence of an 'exclusome', a cytoplasmic container that appears to explain where extra-chromosomal DNA goes once it is in a cell.

Macrophages Play Central Role in Intestinal Cell Renewal

A research team comprising members from MedUni Vienna and the FWF-sponsored Special Research Area SFB F83 Immunometabolism has made a groundbreaking discovery, highlighting the central role of macrophages in the regeneration of intestinal cells.

Regulator Gene for Intestinal Stem Cells Discovered

When a cell dies, a new one has to be formed in its place. This is a regular occurrence in the intestines, where cells are especially exposed to harmful effects.

Unraveling the Link Between Chromosomal Instability and Cancer Spread

Chromosomal instability is a phenomenon marked by rapid alterations in the count and configuration of chromosomes during cell division. This occurrence is prevalent in solid tumors and is closely associated with the aggressive dissemination of cancer, known as metastasis.

Understanding Tissue Development and Regeneration in Fruit Flies

Recently, Kyoto University researchers have unveiled a pivotal discovery: they have determined that the Dumpy protein, a constituent of extracellular matrices (ECM), plays a central role in governing the precise, origami-like folding of wing-cell sheets.

Targeted MicroRNA-34a Therapy Shows Promise in Slowing Tumor Growth in Mice

A new cancer therapy developed by Purdue University researchers attacks tumors by tricking cancer cells into absorbing a snippet of RNA that naturally blocks cell division.

Study Reports High-Resolution Structures of CAF-1

Since the passage of the DNA replication fork destroys nucleosomes on the DNA, chromatin inheritance during cell division requires the replication of DNA and the assembling of nucleosomes onto the duplicated DNA.

Study Shows How Genomic Topography Influences Where Cancer Mutations Arise

Researchers at the University of California San Diego have uncovered a connection between the topography of the human genome and the presence of mutations in human cancer. They found that certain regions of the genome, which exhibit unique features, act as hotspots for the accumulation of mutations.

Scientists Uncover New Mechanism for Degrading Short-Lived Proteins

Short-lived proteins control gene expression in cells to carry out a number of vital tasks, from helping the brain form connections to helping the body mount an immune defense. These proteins are made in the nucleus and are quickly destroyed once they've done their job.
