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.

Wilmot Researchers Uncover a "Genomic Tug of War" That Influences Decitabine's Effectiveness

Some patients with myelodysplastic syndromes, like acute myeloid leukemia, benefit from a chemotherapy drug called decitabine that stunts cancer growth. But many others are resistant to decatibine's effects or become resistant over time.

Fruit Fly Model Provides Insights into Pathogenesis of New Genetic Disorder

Research conducted in the laboratory of Dr Hugo J. Bellen, a Distinguished Service Professor at Baylor College of Medicine and a principal investigator at the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital, has identified a novel disorder linked to gain-of-function variants in the DOT1L gene.

Study Reports High-Resolution Structures of CAF-1

Since the passage of the DNA replication fork destroys nucleosomes on the DNA, chromatin inheritance during cell division requires the replication of DNA and the assembling of nucleosomes onto the duplicated DNA.

New Insights Into How Genes Are Activated

Genetic information contained within DNA has to be read by specific proteins that enable the process of gene activation to begin – but in many cases, these proteins can't access their targets because DNA strands are bundled up to control what genes are used in the wide range of different cell types.

Entry of Aging-Associated Enzymes into Human Genetic Material

An enzyme that controls aging and other metabolic processes accesses human genetic material to modify gene expression within the cell, according to a new study. Images of a sirtuin enzyme bound to a nucleosome, a tightly packed complex of DNA and proteins called histones, have been created by a team led by Penn State researchers.
