We observed a tight overlap between immunostaining for H4K8 acetylation andhnRNPA2 in the nuclei of tumor cells (indicated by *), whereas the stroma (indicated byred arrows) showed no immunoreactivity to either hnRNPA2 or acetyl-H4K8 antibodies(Figure 4c). The gene discussed is HNRNPA2B1; the disease is neoplasm.
