Lactic Acid as an Epigenetic Metabolite in Glioblastoma [ChIP-Seq]

Glioblastoma is the most common primary malignant brain tumor with an unfavorable prognosis and a reprogrammed metabolism. In order to define the role of lactic acid in the context of glioblastoma epigenetic remodeling, pediatric GBM cells, KNS42, were growth for 24h in different media conditions (starvation media -0.5mM Glucose; 0.5mM Glutamate or physiological media -5mM Glucose; 0mM Glutamate) with or without L-lactic acid for 24h. Thereafter, cells were harvested and samples were subjected to ChIP isolation using H3K27ac and H3K9ac antibodies. DNA was subsequently processed for CHIP sequencing to assess epigenetic changes mediated by lactic acid. KNS42 cells were growth for 24h in different media conditions with or without L-lactic acid for 24h. Thereafter, cells were harvested and subjected to CHIP isolation. DNA was subsequently processed for CHIP sequencing.
