Computational Modeling and Experimental Findings on Nucleosome Constraining in Mitosis

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.

New SPARXS Technique Revolutionizes DNA Sequence Analysis

"DNA, RNA and proteins are the key players to regulate all processes in the cells of our body," Leiden Professor John van Noort explains. "To understand the (mis-)functioning of these molecules, it is essential to uncover how their 3D structure depends on their sequence and for this it is necessary to measure them one molecule at a time. However, single-molecule measurements are laborious and slow, and the number of possible sequence variations is massive."

The Complex Link Between DNA Modification and ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease which remains incurable. The disease is characterized by the selective degeneration of upper motor neurons in the motor cortex as well as the lower motor neurons in the brainstem and spinal cord. The cause of ALS remains unknown in 90 percent of cases, which are referred to as sporadic ALS because there is no family history for the disease. Cumulative evidence suggests that sporadic ALS may result from complex interactions between genetic susceptibility and aging.

Gene Editing Creates Prickle-Free Eggplants for Easier Farming

Eggplants, a staple crop globally, present significant challenges in cultivation and harvesting due to their prickles. These prickles, which serve as a natural defense mechanism, complicate handling and reduce efficiency in agricultural practices. Addressing these issues is crucial for improving farming outcomes. Consequently, researchers are focused on understanding the genetic basis of prickle formation to develop prickle-free eggplant varieties. Based on these challenges, there is a pressing need to conduct in-depth research and identify solutions for more efficient eggplant cultivation.
