CDCA7's Role in DNA Methylation Maintenance Revealed in Recent Study

DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and a major way that DNA is epigenetically marked. Epigenetic modifications can act as on-off switches to regulate gene expression and help generate diverse cell types without changing the underlying DNA sequence. It is how the body ensures that brain-related genes don't get turned on in heart cells, for example.

FAM110A's Dual Role: Orchestrating Microtubule-Actin Interactions in Mitosis

An international research collaboration, led by Prof. Dr. Robert Grosse (Centre for Integrative Biological Signalling Studies and Institute of Clinical and Experimental Pharmacology and Toxicology, University of Freiburg), Dr. Libor Macurek (Institute of Molecular Genetics, Czech Academy of Sciences, Prague) and Dr. Zdenek Lansky (Institute of Biotechnology, Czech Academy of Sciences, Prague) has uncovered a new mechanism of the crosstalk between microtubules and actin cytoskeleton during cell division and revealed unique characteristics of the previously unexplored protein FAM110A.

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.

New Model Reveals How Cells Maintain Epigenetic Memory During Cell Division

Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types in the body.

Study Offers New Understanding of How Stem Cells Divide in Plants

Every time a stem cell divides, one daughter cell remains a stem cell while the other takes off on its own developmental journey.

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.

Researchers show how the production of different macromolecules peaks at different times

Textbooks will tell you that in dividing cells, the production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level.

Proteins’ movement and the spread of antibiotic resistance

Umeå University researchers have figured out how a particular type of protein travels during DNA replication. The discovery could affect the current understanding of how bacteria propagate antibiotic resistance genes.

Scientists discover proteins that may improve CAR-T cell therapy for solid tumor model

The potential of CAR T-cell therapy for the treatment of solid tumors was unlocked in a preclinical trial by researchers at St. Jude Children’s Research Hospital who discovered a molecular mechanism. The findings were released in the journal Nature.

Study uncovers how CD8+ T cells can divide and produce two distinct daughter cells

An immunological problem has been addressed by scientists at St. Jude Children’s Research Hospital. Despite being genetically identical, a CD8+ T cell can divide and produce two functionally different daughter cells.

Researchers may have identified a key intermediate in the transition from prokaryotes to eukaryotes

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning "true kernel") have a cell nucleus that harbors most of the cell's genetic information and includes organisms such as humans, plants and fungi.

Confocal laser scanning microscopy captures high-resolution 3D images of cell division in microalgae

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae.

Study discovers how some proteins ensure repair of errors introduced during DNA replication

Researchers have discovered how specific proteins ensure the rectification of errors introduced into the DNA when it replicates.

New insights into how migrating cells interact in the body

By offering a microscopic "tightrope" to cells, Virginia Tech and Johns Hopkins University researchers have brought new insights into the way migrating cells interact in the body.

Heidelberg team introduces a reproducible division mechanism for synthetic vesicles

One big challenge for the production of synthetic cells is that they must be able to divide to have offspring. In the journal Angewandte Chemie, a team from Heidelberg has now introduced a reproducible division mechanism for synthetic vesicles.

Absence of TRIM37 protein boosts genetic instability in patients with Mulibrey syndrome

Researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER), in collaboration with the Swiss Institute for Experimental Cancer Research (ISREC) have studied the mechanisms behind the higher tendency of people with Mulibrey syndrome to develop tumors.

Proteins act as compasses to guide stem cell division in plants

The stem cells tasked with creating and maintaining biological tissues have a difficult job. They have to precisely divide to form new specialized cells, which are destined to different fates even though they contain identical DNA. An obvious question then is: How do the cells divide in all the right ways to produce a healthy tissue?

Researchers use mathematical modeling to unravel the mechanisms behind tetraploidy

Cell division is a fundamental process that organisms need to reproduce, grow, and make repairs. But when an error disrupts this complex biological process, cellular abnormalities can lead to diseases, such as cancer, where cells are enabled to grow and divide out of control.

Recombineering technique may overcome barriers in bacterial engineering

Genetic engineering of bacteria has transformed contemporary medicine, from bacterial-based insulin to a deeper insight into infectious diseases.
