Epstein-Barr Virus Rewires Host Epigenomes to Drive Stomach Cancer

Researchers have discovered a molecular mechanism that explains how Epstein-Barr virus (EBV) infection alters a host's epigenome to promote tumorigenesis (the transformation of normal cells into ...

FloChiP, a New Tool Optimizing Gene-Regulation Studies

Scientists have developed a tool called FloChip, a new microfluidic take on the widely used chromatin immunoprecipitation (ChIP) technique. By automating and cutting the cost of ChIP and ...

Epigenetics: Inheritance of Epigenetic Marks

A study undertaken by a molecular biologist sheds new light on the mechanisms that control the establishment of epigenetic modifications on newly synthesized histones following cell ...

Histone Modifications Are the Influencers of Zygotic Genome Awakening

Scientists have observed changes to the gene-regulating factors during zebrafish development and discovered that modifications to 'histone H3', one of the proteins around which DNA is ...

Breakthrough in Sex-Chromosome Regulation

Researchers have uncovered a chromosome-wide mechanism that keeps the gene expression of sex chromosomes in balance in our cells. The findings shed light on molecular reasons for early miscarriage ...

Earthquake in the Cell

Nuclear abnormalities such as nuclear blebs and micronuclei have devastating consequences for the genetic material and are associated with cancer or ageing. Scientists now revealed that the ...

Renegade Genes Caught Red-Handed

Potentially dangerous genes embedded within human DNA were once thought to be locked down by helpful DNA structures called heterochromatin. A researcher disputes that belief and hopes to change the ...

Scientists Uncover Mystery of DNA Methylation

To a large extent, DNA methylation, which regulates vital cell functions, is still a big mystery to the scientific world. Now,, scientists have developed a method to quickly couple methylation ...

Scientists Crack the Code to Improve Stress Tolerance in Plants

Epigenetic regulation -- modification of gene expression from the 'outside' -- is an important part of the overall genetic processes within a cell. A group of scientists now reveals a novel ...

The Protein That Gives Identical Cells Individuality

New insight into a protein's role in regulating tight DNA packing could have implications for combating tumor cell resistance to anti-cancer ...

Ancient Epigenetic Changes Silence Cancer-Linked Genes

A study in zebrafish indicates that some genes linked to cancers in humans have been strictly regulated throughout ...

Scientists Crack the Code to Regenerate Plant Tissues

A group of scientists have discovered a new way to regenerate flowering plant tissues, opening possibilities of mitigating global food shortage ...

Effects on Offspring of Epigenetic Inheritance Via Sperm

As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene ...

Breakthrough in Fight Against Plant Diseases

Scientists have identified specific locations within plants' chromosomes capable of transferring immunity to their ...

A Quick Path to Antimalarial Resistance

Resistance to antimalarial drugs is thought to result mainly from changes in the parasite's genome. However, P. falciparum can also develop resistance to some antimalarial compounds by ...

Infection Biology: What Makes Helicobacter So Adaptable?

The bacterial pathogen Helicobacter pylori owes its worldwide distribution to its genetic adaptability. Microbiologists have identified an enzyme that plays a vital role in the flexible control of ...

Time-Lapse Microscopy Helps Reveal Brake Mechanism in Streptomyces Lifecycle

Streptomyces are soil-dwelling bacteria that produce approximately two-thirds of the antibiotics in current clinical ...

Novel Autism Mouse Model Based on an Epigenetic Gene Developed

In a new study, researchers describe how, in a novel mouse model, epigenetic regulation negatively impacts a downstream gene specifically involved in neurodevelopment and associated ...

Keeping Chromosomes in Check: A New Role for Heterochromatin

Large changes in the structure of chromosomes are usually fatal for the cell or can lead to genetic diseases such as cancer. Many large chromosomal rearrangements stem from short runs of repeated DNA ...

Not in the DNA: Epigenetics Discovered in Single-Celled Archaea

Researchers have reported the first experimental evidence of epigenetics in the single-celled organisms known as archaea. The simplicity of archaea -- combined with the fact that their cells resemble ...
