Study sheds light on homologous recombination of DNA strands

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub.

Study offers new insight into how cells fuse

Scientists have known for a decade that cells that fuse with others to perform their essential functions - such as muscle cells that join together to make fibers - form long projections that invade the territory of their fusion partners.

A key player in hepatitis A virus infection discovered

How hepatitis A virus manages to enter liver cells called hepatocytes and initiate infection had remained a mystery for fifty years until now.

Collagen maturation regulates PEDF availability, study shows

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.

Minuscule tracking devices give unprecedented peek into how cells change with time

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.

The eye initiates an immune response in the lens after injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see.

Warwick researchers discover how cells activate autophagy genes during fasting

As modern life-styles and high calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier lifestyle can be promoted to help people maintain a healthy body weight.

New technique for fast, easy optimization of antibodies using chicken cells

Antibodies for potential use as medicines can be made rapidly in chicken cells grown in laboratories. Researchers refer to their technique as the human ADLib system, short for autonomously diversifying libraries.

Rejuvenated fibroblasts could be used in regenerative medicine, stem cell engineering

Fibroblasts are the most common connective tissue cells. They produce the structural framework for animal tissues, synthesize the extracellular matrix and collagen, and play a critical role in wound healing.

Researchers identify genetic mechanisms that produce radioresistance in cancer cells

Cancer stem cells are a cell type that was previously little known. They are resistant to irradiation and prevent the effective treatment of many types of cancer. A research group from Innsbruck has now identified two genetic mechanisms that produce this radioresistance.
