The Nek9 protein is required for chromosomes to separate into two identical groups. Nek9 exerts its action between two molecules of interest for the pharmaceutical industry as anti-tumoral agents, and for which inhibitors are already in advanced stages of clinical trials. Nek9 could be added to the list of candidates. A study by the Institute for Research in Biomedicine (IRB Barcelona) and the Center for Genomic Regulation (acronym in Catalan CRG) highlights the protein Nek9 as a...

Stowers team reconciles puzzling findings relating to centromere structure Scientists at the Stowers Institute of Medical Research have developed an innovative method to count the number of fluorescent molecules in a cluster and then applied the novel approach to settle a debate rampant among cell biologists–namely, how DNA twists into a unique chromosomal structure called the centromere. Knowing this helps explain how cells navigate the hazards of division and avoid the disastrous...

Children's Hospital of Philadelphia researchers shed light on genetic disorders tied to cohesin protein malfunction Researchers studying rare genetic disorders have uncovered insights into those diseases in biological structures that regulate chromosomes when cells divide. Focusing on the cohesin complex, a group of proteins forming a bracelet that encircles chromosome pairs, scientists have discovered mutations that disrupt cohesin, causing a recently recognized class of diseases called...

DNA Replication Protein Plays Role In Cancer

The foundation of biological inheritance is DNA replication This is a coordinated process in which DNA is copied at hundreds of thousands of different sites across the genome at the same time. If the copying mechanism doesn't work properly, the result may be cells with missing or extra genetic material, a hallmark of the genomic instability seen in most birth defects and cancers. Scientists at the University of North Carolina School of Medicine have discovered a protein known as Cdt1....

They have identified new functions of cohesin SA1 that are relevant for cancer and CdLS Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of...

Quantitative research shows key organelle of cell division to be more complex than previously thought The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences (SEAS). The researchers used a femtosecond laser to slice through the strands of the organelle and then performed a mathematical analysis to infer the...

(Ivanhoe Newswire)-- Yale researchers have discovered how megakaryocytes or giant blood cells that produce wound healing platelets grow 10 or more times bigger than other blood cells and how they may cause a form of leukemia. "A failure of these cells to grow might be an initial trigger for megakaryoblastic leukemias," Diane Krause, senior researcher for the Yale Cancer Center, professor of laboratory medicine, cell biology, and pathology and associate director of the Yale Stem Cell...

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis? "People have been looking at these proteins and players in mitosis for decades, and no one ever...
