Drugs designed to lower alpha-ketoglutarate levels could help fight DIPG tumors

Every year, 150 to 300 children in the United States are diagnosed with diffuse intrinsic pontine gliomas (DIPGs), aggressive and lethal tumors that grow deep inside the brain, for which there are no cures.

Genetic analysis reveals the inhibitory role of NSD2 enzyme in cellular senescence

Using a detailed genetic analysis, a research team from Japan-based Kumamoto University has discovered that the NSD2 enzyme, which controls the actions of several genes, also functions to block the aging of cells.

Study uncovers molecular mechanism of metabolite-mediated epigenome involved in organismal aging

Scientists have recently demonstrated that acetyl-CoA connects mitochondrial stress to the nuclear epigenome through the NuRD complex.

New tool predicts and identifies novel genes involved in various biological processes

Chromatin plays a significant role in the silencing and activation of gene transcription, and establish the fate of the cells during development.

Lessons from early embryo could increase the efficiency of cell reprogramming

Cell reprogramming provides an outstanding opportunity for the artificial generation of stem cells for regenerative medicine approaches in the clinic.

Study reveals how and where cells suppress transcription across the whole genome

All life depends on a genome, which acts as an instruction manual for building all the products essential for development and survival. But knowing which of these individual instructions - or genes - need to be read, and when, is key for a properly functioning organism: so how does life get this right?

Study uncovers why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.

Biochemical and computational methods for large-scale protein-arginine methylation analysis

Methylation (namely addition of a methyl group) of arginine amino acid residues of proteins is a post-translational modification (PTM) catalyzed by a family of nine enzymes called Protein Arginine Methyl-Transferases (PRMTs).

Aging neurons build up DNA damage, study finds

MIT neuroscientists have discovered that an enzyme called HDAC1 is critical for repairing age-related DNA damage to genes involved in memory and other cognitive functions.

Histones Are Crucial For Adaptation To Cell Stress

The genetic material, DNA, of plants, animals, and humans is stored inside the cell, and DNA packing is guaranteed by proteins called histones.

Force can activate genes without intermediates, enzymes, or signaling molecules

A new study reports that cells tend to increase gene expression as a response to physical forces alone. According to the team, the initial step in the production of proteins—gene activation—begins within 1 ms once a cell gets stretched, which is hundreds of times faster than chemical signals can travel.
