ChIP studies assessing STAT3, NF-kB, and AP-1 TF binding to the HCK promoter. The fold enrichments of HCK promoter-specific sequence assessed by quantitative PCR following ChIP with ChIP grade antibodies to STAT3, NF-kB-p65, JunB, and c-Jun in MYD88-mutated WM (BCWM.1, MWCL-1) and ABC-DLBCL (TMD-8, HBL-1, OCI-Ly3) cells, and MYD88 wild-type lymphoma cells (OCI-Ly7, OCI-Ly19). Antibody to GAPDH was used as control antibody.
