Location-Dependent Gene Expression in Ovarian Cancer: Insights from 3-D Models

Variations in gene activity based on where a cell is in a tumor have been discovered by researchers with the help of 3-D models of ovarian cancer tumors.

Key Atomic Structures of the Actin Filament Revealed Through Cryo-EM

Actin filaments -; protein structures critical to living movement from single cells to animals -; have long been known to have polarity associated with their physical characteristics, with growing "barbed" and shrinking "pointed" ends.

Understanding Potential Mechanisms Underlying Genetic Variation in Older Trees

Older, long-lived trees are thought to contribute more to the creation and maintenance of genetic mutations than short-lived trees, according to research on the link between the growth rate of tropical trees and the frequency of genetic mutations they collect.

Fission Yeast Analysis Reveals Two Key Genes Involved in Gross Chromosomal Rearrangement

When creating a computer program, errors in the code can introduce bugs to the software. Similarly, errors in our body's genetic code, DNA, which is stored in structures known as chromosomes, can bring about mutations in the body.

Role of SWI/SNF Chromatin Remodeling Complex in Cell Division

A previously unknown function for the SWI/SNF chromatin remodeling complex has been revealed by researchers at St. Jude Children’s Research Hospital.

Study Shows How Excess Dietary Sugar Worsens IBD Symptoms

Excess sugar hampers cells that renew the colon's lining in a mouse model of inflammatory bowel disease (IBD), according to a new study by University of Pittsburgh scientists.

Researchers Examine the Role of TOR in LR Formation and its Interplay with Auxin Signaling

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to research team leader Prof. Dr Alexis Maizel of the Centre for Organismal Studies at Heidelberg University.

New Insights Into How Diverse Chromosomal Alterations Form and Drive Cancer Development

The goal of every dividing cell is to accurately segregate its genome into two genetically identical daughter cells.

Understanding How Supernumerary Chromosomes Arise

The majority of chromosomes have existed for millions of years.

Study Uncovers Cancer-Like Changes in Mitochondrial Disease of Newborns

A study found that a mitochondrial disease of newborns shows cancer-like changes in proliferating cells, causing tissues to age prematurely.

Analyzing the Cell Division in Stem Cells

What appears to be a simple task for a cell—splitting in two—is indeed a complex series of engineering puzzles. To produce two working cells, a splitting cell has to maneuver its interiors in such a way that the appropriate components will end up in each cell.

Study Reveals How the Formation of Microtubules Drives Cell Division

Cellular life hinges on a network of hollow cables called microtubules dynamically lengthening and shortening according to the needs of the moment.

Modulation of ERK Signaling Could be Used to Stimulate Regeneration

Why do some animals regenerate lost tissues after injury while others don't? Researchers from the lab of Kerstin Bartscherer (Osnabrück University and formerly Hubrecht Institute) and Ashley Seifert (University of Kentucky) studied spiny mice, which have a remarkable regenerative capacity, to answer this question.

Spatial Organization of Chromosomes and the Role of DNA Tension

Two protein complexes are primarily responsible for chromosomal spatial organization in human cell nuclei. DNA tension has an unanticipated function in this. Together with Austrian colleagues, nanoscientist Cees Dekker and his PhD candidate Roman Barth of TU Delft’s Kavli Institute of Nanoscience published their detailed visualization in Nature on April 19th, 2023.
