IMB scientists unravel complex regulatory mechanism involved in brain development

Scientists at the Institute of Molecular Biology in Mainz have unraveled a complex regulatory mechanism that explains how a single gene can drive the formation of brain cells. The research, published in The EMBO Journal, is an important step towards a better understanding of how the brain develops. It also harbors potential for regenerative medicine.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

DNA study reveals basic principle of gene regulation

A study of where and how an enzyme cuts DNA may have inadvertently revealed a basic principle of gene regulation, say researchers in Boston Children's Hospital's Program in Cellular and Molecular Medicine (PCMM).

Active nuclear deformations contribute to formation of intra-nuclear chromosome architectures

There are two types of chromatin, euchromatin and heterochromatin, that vary with the stages of the cell cycle. In particular, euchromatin with rich active genes localizes to the interior of the nucleus during interphase; heterochromatin usually localizes to the periphery of the nucleus.

Proposed thin-plate model sheds light on structural basis of chromosomal aberrations in cancer cells

During cell division, each metaphase chromosome contains a single enormously long DNA molecule that is associated with histone proteins and forms a long chromatin filament with many nucleosomes.

Scientists find how cells adapt to overcome cancer drugs

CANCER RESEARCH UK scientists have found how cells adapt to overcome cancer drugs designed to interfere with their genetic controls, according to a study published today (Wednesday) in Epigenetics and Chromatin.

Penn Medicine researchers show that DNA editing errors can lead to cancer

Sometimes when the immune system makes small mistakes, the body amplifies its response in a big way: Editing errors in the DNA of developing T and B cells can cause blood cancers. Now, researchers from the Perelman School of Medicine, University of Pennsylvania have shown that when the enzyme key to cutting and pasting segments of DNA hits so-called "off-target" spots on a chromosome, the development of immune cells can lead to cancer in animal models.

Study reveals new epigenetic mechanism underlying progression of cancer tumors

Aggressive cancer growth and alterations in gene activity without changes in DNA sequence (epigenetics) are associated with mutant p53 proteins, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

BET inhibitors can cause molecular changes in neurons, lead to memory loss in mice

Cancer researchers are constantly in search of more-effective and less-toxic approaches to stopping the disease, and have recently launched clinical trials testing a new class of drugs called BET inhibitors. These therapies act on a group of proteins that help regulate the expression of many genes, some of which play a role in cancer.

New set of genes can indicate improved survival after surgery for pancreatic cancer patients

A study by the Translational Genomics Research Institute and other major research institutes, found a new set of genes that can indicate improved survival after surgery for patients with pancreatic cancer. The study also showed that detection of circulating tumor DNA in the blood could provide an early indication of tumor recurrence.

MD Anderson scientists reveal role of metabolic enzyme fumarase in DNA repair

DNA double-strand breaks (DSBs) are the worst possible form of genetic malfunction that can cause cancer and resistance to therapy. New information published this week reveals more about why this occurs and how these breaks can be repaired.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

New technology enhances investigations of epigenomes

A new technology that will dramatically enhance investigations of epigenomes, the machinery that turns on and off genes and a very prominent field of study in diseases such as stem cell differentiation, inflammation and cancer, is reported on today in the research journal Nature Methods.

Vital molecular mechanism in plants has similarities to certain signaling mechanisms in humans

Scientists at Van Andel Research Institute have revealed an important molecular mechanism in plants that has significant similarities to certain signaling mechanisms in humans, which are closely linked to early embryonic development and to diseases such as cancer.
