  • Histones and Histone Modifications | Life Science Research | Merck

    Histone modifications regulate DNA transcription, repair, recombination, and replication, and can alter local chromatin architecture. Understanding histone modifications is key to uncovering epigenetic mechanisms of gene regulation. Merck grasps the complexity of this research and provides a growing line of kits, antibodies, and assays for studying histones and their modifications. Merck offers over 600 validated antibodies, recombinant proteins, and kits to analyze histone and histone-variant phosphorylation, methylation, acetylation, ubiquitination, and citrullination-the most widely studied histone modifications in epigenetics today.
  • Nuclear Function | Life Science Research | Merck

    A Nuclear function is to be home of an entire genome that can physically fit inside the nucleus and to allow the cell to differentiate, divide, and endure environmental stresses while protecting its valuable genetic information.
  • Genomic instability | Life Science Research | Merck

    Learn about the environmental factors that can hinder DNA repair. There are many evidence linking genomic and epigenomic changes to disorders involving accelerated aging. Evidence points to general physiological stress and disrupted circadian. It is also possible that decreased DNA repair is also a symptom, not a cause, of aging. To investigate this possibility, researchers will need to examine changes in transcriptional regulators of repair genes, such as ncRNAs, hormones, and other chromatin modulators.
  • Deregulated Nutrient Sensing | Life Science Research | Merck

    Organisms depend on multiple nutrient sensing pathways to make sure that the cells and tissue obtain just the right amount of necessary nutrients. Metabolic activities can put stress on our cells. Too much activity, and changes in nutrient availability and composition cause cells to age faster.
