Mrc1 protein identified as key to maintaining cell identity during division

In a major scientific breakthrough, researchers have found that a protein called Mrc1 plays a crucial role in ensuring that cells keep their identity as they divide and grow.

Study reveals serotonin's role in ependymoma tumor growth

Do neurons play a role in brain tumor growth and development? Scientists at St. Jude Children's Research Hospital and Baylor College of Medicine have evidence showing that, for childhood ependymomas, they do.

Salk researchers unveil SWI/SNF variants' role in macrophage immune responses

Bacteria, parasites, viruses-;the immune system tackles them all. At the front line of the human immune response are cells called macrophages, which are responsible for correctly identifying intruders and then directing how the entire immune system responds.

Unlocking glioblastoma's immune suppression mechanism

The Wistar Institute assistant professor Filippo Veglia, Ph.D., and team, have discovered a key mechanism of how glioblastoma -; a serious and often fatal brain cancer -; suppresses the immune system so that the tumor can grow unimpeded by the body's defenses.

Link between aldehydes and premature aging revealed

A team of researchers at Nagoya University in Japan has discovered that aldehydes are metabolic byproducts associated with premature aging.

Anti-cancer drug shows promise in treating brain injuries after stroke

A study by the Institut de Neurociències of the UAB (INc-UAB) demonstrates in animal models the benefits of vorinostat after having suffered a stroke.

Study sheds light on the composition of nuclear matrix in Arabidopsis thaliana

Chromatin is a unique DNA and protein complex that makes up the chromosomes. Specific proteins (histones) wind up the DNA like small cable drums to package the long DNA.

Breakthrough technique unveils secrets of "backtracking" in gene regulation

A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows.

MAbID offers a deep dive into chromatin dynamics and gene regulation

Researchers from the group of Jop Kind developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease.

Scientists uncover "genomic tug of war" that influences chemotherapy'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.

New insights into how cells maintain their identity over generations

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.

New approach to CAR T cell therapy may extend treatment effectiveness

CAR T cell therapy, a powerful type of immunotherapy, has begun to revolutionize cancer treatment. Pioneered at Memorial Sloan Kettering Cancer Center (MSK), the therapy involves engineering a patient's T cells so they recognize and attack cancer cells.

Study reveals molecular mechanism behind new DOT1L-related disorder

A study from 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 discovered that gain-of-function variants in the DOT1L gene cause a new disorder.
