Webb26 maj 2024 · Histone post translational modifications (PTMs) are a prominent epigenetic factor that affects nearly all genetic pathways within the nucleus. The histones within cells are responsible for binding DNA into tight coils known as chromatin. WebbUsing a mass spectrometry-based label-free and chemical stable isotope labeling quantitative proteomic approach, we systematically profiled liver histone post-translational modifications (PTMs) in a prediabetic high-fat diet-induced obese (DIO) mouse model. We identified 170 histone marks, 30 of which were previously unknown.
