Researchers discover new regions of non-coding DNA that may lead to cancer growth

In an unprecedented pan-cancer analysis of whole genomes, researchers at the Ontario Institute for Cancer Research have discovered new regions of non-coding DNA that, when altered, may lead to cancer growth and progression.

Study sheds new light on impact of common plasticizer on human reproductive health

Researchers at Harvard Medical School and the New York State Department of Health have discovered how a common plasticizer associated with human reproductive abnormalities likely does its damage at the molecular level.

Study shows potential new approach to treating two common subtypes of lymphoma

A study at The University of Texas MD Anderson Cancer Center demonstrated a potential new approach to treating two of the most common subtypes of lymphoma through manipulation of molecular programs controlled by the cAMP-response element binding protein.

Mount Sinai awarded more than $10 million in federal funding for research on glioblastoma

The Department of Neurosurgery at the Icahn School of Medicine at Mount Sinai has received more than $10 million in federal funding for several projects focusing on brain tumor research.

Common plasticizer leads to fertility problems in roundworms

A new study published 9th January in PLOS Genetics by Mónica Colaiácovo of Harvard Medical School and colleagues reports that the most commonly used plasticizer, diethylhexyl phthalate, leads to fertility problems by causing an excess number of breaks in the DNA during egg production, and then interfering with the repair systems that fixes the breaks.

Study opens up new treatment possibilities for Wilms' tumor

As an embryo develops, its cells must learn what to do with the thousands of genes they've been equipped with. That's why each cell comes with a detailed gene-expression manual outlining exactly which genes should be switched on, to what extent, and when.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Important discovery about male infertility could lead to new treatments

Using a new mouse model, Penn Medicine researchers have identified defects in the sperm epigenome that cause male infertility.

Epigenome editing could repair genetic brain disorder

A new study published in the journal Nature Communications shows that it may be possible to reverse gene mutations that cause brain disorders, using a very precisely targeted epigenome editing technique. This type of gene editing does not change the gene’s DNA sequence itself but is focused on correcting epigenome changes only. The condition that was corrected in the study is called the WAGR syndrome and is associated with obesity and intellectual disability in people.

New discovery on chromosomal function may shed light on human health and disease

Researchers have discovered key mechanisms and structural details of a fundamental biological process-;how a cell nucleus and its chromosomal material reorganizes itself after cell division

Epigenomic techniques used to fight disease

Humans differ from one another in many ways, including how they react to disease, because of their DNA blueprint, as well as the difference in the environments they face. These factors combine to make each person unique. Now a new study published in the journal Nature Protocols reports the development of a promising technology to uncover the process by which the body fights diseases in different ways.

Researchers create new technology to help understand how the body battles diseases

Much remains unknown about diseases and the way our bodies respond to them, in part because the human genome is the complete DNA assembly that makes each person unique. A Virginia Tech professor and his team of researchers have created new technology to help in understanding how the human body battles diseases.

Freiburg scientists decipher basic molecular control mechanisms behind cellular identity

A research team headed by Prof. Dr. Sebastian Arnold and Jelena Tosic from the Faculty of Medicine at the University of Freiburg has now succeeded in deciphering basic molecular control mechanisms by which stem cells decide which embryonic cell types to turn into.

Scientists uncover functions of mysterious organelles in stress response

Stress is a normal response to physical and emotional stimuli, particularly when people face changes in their lives. Though it’s a normal feeling, long-term stress may lead to a range of health conditions. Though people feel stressed from time to time, not all stress is bad.

Researchers identify a promising drug pair to attack deadly childhood brain cancers

Researchers have devised a new plan of attack against a group of deadly childhood brain cancers collectively called diffuse midline gliomas, including diffuse intrinsic pontine glioma, thalamic glioma and spinal cord glioma.

Newly developed ChiTaRS database can collect cases of druggable fusion targets

When sections from two separate genes merge due to various factors, such as translocation or splicing, the hybrid that is formed is called a gene fusion. In recent years, it has been discovered that these fusion events play a vital role in the development of cancers and other complex diseases.

Mechanisms preserving cell identity are based on status of proteins housing DNA

The inheritance, not only of DNA, but of changes to proteins that package it, maintains the identity of cells as they multiply, a new study finds.

Scientists receive $1.6 million grant to study impact of phthalate exposure on male fertility

A cross-disciplinary team of scientists, led by University of Massachusetts Amherst environmental epigeneticist Richard Pilsner, will use a three-year, $1.6 million grant from the National Institute of Environmental Health Sciences to expand research into the impact of phthalate exposure on male fertility.

Some types of proteins can stabilize damaged DNA

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins cannot keep their DNA stable and develop diseases such as cancer.

Study finds molecular key to formation of mature and fully functioning T cells

In a finding that could help lead to new therapies for immune diseases like multiple sclerosis and IBD, scientists report in the Journal of Experimental Medicine identifying a gene and family of proteins critical to the formation of mature and fully functioning T cells in the immune system.
