FOXP1 and hepatocellular carcinoma: The experiments involved ChIP-seq against H3K4me3 –a histone mark associated with euchromatin– in B-cells –responsible for humoral responses of the immune system–, H3K79me1 –also associated with euchromatin– in a cell line isolated from normal lung fibroblast tissue (IMR-90), and the transcription factor FOXP1 in a cell line isolated from hepatocellular carcinoma (HepG2).
