However, at least at the RNA level, we could not detect the altered expression of the major H3K27-HMT EZH1 and EZH2, which other studies have shown in force-stressed HPdLSCs and pathogenically stimulated human B cell lymphoma cells, such as BCBL1 [54,70]. This evidence concerns the gene EZH1 and B-cell non-Hodgkin lymphoma.
