PKN1 and lung adenocarcinoma: We did not find a combination of histone acetyltransferases or histone deacetylases that were overexpressed or underexpressed among the lung adenocarcinoma cell lines, even if we excluded a cell line, A427, that lacks the H3K27ac histone modification among all three genes (NUP210, PKN1, and PPP1R9A) (“presence/absence of H3K27ac modification” in S8 Table).
