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 Delves Deeper into Understanding How Humans Behave

Throughout a person’s life, many stimuli can turn on and off many of the genes, resulting in the variances that distinguish people.

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.

New Mechanism to Maintain Astrocyte-Neuron Communication

Neurons and astrocytes are the two types of cells required by the brain to enjoy the scent of morning coffee and freshly baked cookies or to discern the warning smell of something burning.

How Epigenetic Landscape Impacts Pioneer Transcription Factor Binding

St. Jude Children’s Research Hospital researchers are investigating how a type of transcription factor known as a pioneer transcription factor reaches DNA even when it is tightly wrapped.

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.

The Modified Development Potential of Worm Embryonic Cells

A startling discovery that challenges the conventional wisdom that the majority of the hereditary information for cell differentiation is encoded within DNA and other genetic factors has been made regarding how specific proteins within the chromosomes of roundworms facilitate their offspring to develop specialized cells generations later.

Study elucidates the structure of centromeric region in chicken cells

The genetic material inside cells is organized into structures called chromosomes. The centromere is essential for the correct division of the chromosomes via interaction with spindle microtubules when cells divide and grow.

Molecular regulation underlying emergency hematopoiesis uncovered

If the body’s emergency hematopoiesis program activates, it signifies an alert state of the immune system and serves two functions: In comparison to “normal mode” hematopoiesis, the emergency program results in enhanced replacement of immune cells consumed during infections or inflammations.

Researchers uncover a mechanism of flowering plant sperm compaction

Sperm cells have compact bundles of DNA, yet exactly how and why sperm cell nuclei are condensed in flowering plants has been a mystery, until now.

Study discovers a molecular mechanism that confers special physical properties to chromosomes in dividing human cells

The Gerlich Group at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) has identified a molecular process that gives chromosomes in dividing human cells unique physical characteristics that permit faithful transmission to the progeny.

Yale and uOttawa researchers partner to solve a puzzle rooted in the deepest past of evolution

For decades, scientists have been trying to unravel an enduring mystery of structural biology: Why do two otherwise identical protein forms found in everything from plants, amphibians and human beings hang onto a slight variation across the mighty span of evolution?
