Study: New histone modifications link cellular metabolism to chromatin architecture

Scientists of Helmholtz Zentrum München and Ludwig-Maximilians-Universität Munich (LMU) have discovered that two new classes of histone modifications couple cellular metabolism to gene activity. The study was published in 'Nature Structural and Molecular Biology'.

Researchers propose LSD1 protein as central player in Alzheimer's and FTD

Removal of a regulatory gene called LSD1 in adult mice induces changes in gene activity that that look unexpectedly like Alzheimer's disease, scientists have discovered.

UAB researchers reveal key role for RSF1 protein in silencing genes

A fertilized human egg develops into multiple tissues, organs and about 200 distinct cell types. Each cell type has the same genes, but they are expressed differently during development and in mature cells.

Researchers investigate genetic mutations in sperm cells to help prevent birth defects

It's about preventing birth defects. Associate pharmaceutical sciences professor Wenfeng An and his team at South Dakota State University are investigating mobile DNA segments, known as L1s, in sperm cells with the goal to treat families at risk for genetic mutations before they conceive.

Researchers discover broad role for DNA-cutting enzyme in driving abnormal genetic rearrangements

Researchers studying a DNA-cutting enzyme with a crucial role in regulating the structure of genes have discovered a broad role for its cutting activity in driving abnormal genetic rearrangements called translocations that cause cancer, including leukemias and solid tumors.

Moffitt researchers develop novel drug that may help combat castration-resistant prostate cancer

Prostate cancer is the third most common cause of cancer-related death in men in the United States. It is estimated that 161,360 men will be diagnosed and more than 26,700 men will die from the disease in this year.

Study suggests promising therapeutic strategy for childhood brain tumor

A study published in Molecular Cancer Research reveals that a tumor suppressor gene p16 is turned off by a histone mutation (H3.3K27M), which is found in up to 70 percent of childhood brain tumors called diffuse intrinsic pontine glioma (DIPG).

UNC researchers discover cascade of gene activity during journey to maturation in fruit flies

Every animal starts as a clump of cells, which over time multiply and mature into many different types of cells, tissues, and organs.

Study reveals how enzyme allows brain tumors to grow despite harsh surroundings

All cancer tumors have one thing in common – they must feed themselves to grow and spread, a difficult feat since they are usually in a tumor microenvironment with limited nutrients and oxygen.

Mayo Clinic research advances understanding of DNA repair mechanisms

We humans like to think our DNA is well-protected in the nucleus of each cell. But it's a hard life for the hard-working genetic code.

Researchers discover new mechanism of epigenetic inheritance in fruit flies

Giacomo Cavalli's team at the Institute of Human Genetics (University of Montpellier / CNRS), in collaboration with the French National Institute for Agricultural Research, has demonstrated the existence of transgenerational epigenetic inheritance among Drosophila fruit flies.

Researchers take important step toward using transplanted fetal cells to treat liver failure

In a new study, researchers demonstrate successful transplantation of fetal rat liver cells to an injured adult rat liver. The work is an important step toward using transplanted cells to treat liver failure, which currently requires an organ transplant.

Combining anticancer drug with antirheumatic produces improved effects against tumors

Scientists at EPFL and NTU have discovered that combining an anticancer drug with an antirheumatic produces improved effects against tumors. The discovery opens a new path for drug-drug synergy.

Scientists show p300 protein may stop MDS from developing into leukemia

Scientists at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine have shown that p300, a protein that increases gene expression by attaching acetyl molecules to DNA, may stop myelodysplastic syndrome (MDS) from developing into acute myeloid leukemia (AML). The study was published in the journal Leukemia.

Penn researchers identify genome-wide changes caused by high-fat diet

By comparing two strains of mice -- one that becomes obese and diabetic on a high-fat diet and another resistant to a high-fat regimen -- researchers from the Perelman School of Medicine at the University of Pennsylvania identified genome-wide changes caused by a high-fat diet.

MGH researchers discover regulators of gene expression programs in medulloblastoma

Massachusetts General Hospital researchers have identified a mechanism that controls the expression of genes regulating the growth of the most aggressive form of medulloblastoma, the most common pediatric brain tumor. In their report published online in Cancer Discovery, the team also identifies potential targets for future treatments.
