First Evidence of Oocyte Cohesion Rejuvenation Discovered in Fruit Flies

A Dartmouth study conducted on fruit flies reports the first evidence in any organism that oocytes-;the cells that become eggs-;regularly rejuvenate the critical protein linkages that bind chromosomes together.

Multiciliated Cell Differentiation Regulated by an Alternative Cell Cycle

A fertilized egg can develop into a baby through the amazing process of cell division, while a malignant cell can become a malignant tumor. Since there is so much on the line, nature maintains strict control over it through a mechanism known as the cell cycle that scientists once believed they thoroughly understood.

Researchers Identify Molecular Stop Signal in Cell Division Monitoring

Every second, many million cells divide throughout the body. During nuclear division (mitosis), the genetic material must be divided correctly and fully amongst daughter cells; faults in this process can result in improper development or genetic diseases, and many cancer cells have an uneven number of chromosomes.

Unmasking XPD’s Mechanism in DNA Damage Detection and Repair

The way the protein XPD recognizes severe DNA damage and regulates its repair was uncovered by researchers at the University of Würzburg, under the direction of Caroline Kisker and Claudia Höbartner.

Exploring the Evolution of Mitosis: Lessons from Close Relatives of Fungi and Animals

Cell division is one of the most fundamental processes of life. From bacteria to blue whales, every living being on Earth relies on cell division for growth, reproduction, and species survival.

Supercomputer Simulations Unveil Mechanisms of Fruit Fly Wing Development

If fruit fly wings do not develop into the right shape, the flies will die. UC Riverside researchers have learned how fly embryo cells develop as they need to, opening a window into human development and possible treatments for birth defects.

Discovery of New Cancer Cell Death Pathway Involving Schlafen11 Gene

Chemotherapy kills cancer cells. But the way these cells die appears to be different than previously understood.

New Insights Into Centromere Structure: Two Subdomains Revealed

Researchers from the Kops group in collaboration with researchers from the University of Edinburgh, made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides.

Protein Complex Movement May Regulate Cell Division, Impacting Disease Research

Scientists at Umeå University in Sweden have found that the movement of a unique protein complex known as the Mediator along DNA genes may affect the process of cell division.

First Comprehensive Map of Protein Movement in Yeast Cell Cycle Revealed

An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle.

Insights into Bacterial Cell Division: Beyond Size Considerations

When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass.

Different Chromosomes Found to Have Separate End-Specific Telomere-Length Distributions

We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury.

UC San Diego Scientists Uncover Mechanism Behind Mitosis Timing

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells.

Penn Researchers Develop Breakthrough Technique for Creating Human Artificial Chromosomes

Human artificial chromosomes (HACs) capable of working within human cells could power advanced gene therapies, including those addressing some cancers, along with many laboratory applications, though serious technical obstacles have hindered their development.

'lncREST' RNA Unveiled as Key Player in DNA Replication Stress Response

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and repairing errors in DNA replication during cell division.
