In this study, knockdown of EZH2 significantly inhibited TNBC cell proliferation and impaired cell migration and invasion, whereas overexpression of EZH2 produced an inverse phenotype.

Stable knockdown of EZH2 using lentiviral shRNA vector significantly reduced the proliferation, migration and invasion abilities of TNBC cell line MDA-MB-231 and MDA-MB-468, and downregulated NSD2 expression as well as the levels of H3K27me3 and H3K36me2, two histone methylation markers catalyzed by EZH2 and NSD2, respectively.

Based on the results of the present study, we speculated that EZH2 may enhance the transcription of NSD2 though interacting with some transcription factors or co-factors in TNBC.

A previous report suggested that the regulation of NSD2 expression by EZH2 may occur at the posttranscriptional level through microRNAs network.

EZH2 Mediated Oncogenic Effects Require NSD2 Expression.

By contrast, adenovirus mediated EZH2 overexpression significantly increased NSD2 expression as well as the methylation levels of H3K27 and H3K36 in MDA-MB-231 cells (XREF_FIG).

Thus, we next checked whether the binding of DDX11 and EZH2 may affect the ubiquitination of EZH2 in HCC cells.

Results demonstrated that the ubiquitination of EZH2 protein was obviously enhanced by the depletion of DDX11 ( xref ).

Functionally , DDX11 promoted cell proliferation by inducing the expression of EZH2 , a famous oncogene ( 20 , 25 ) , to subsequently inhibit the expression of p21 , a well-known tumor suppressor .

DDX11 expression was upregulated by the positive feedback loop of EZH2 and E2F1.

We thus speculated that EZH2 may cooperate with E2F1 to induce DDX11 transcription.

Our in vitro experiments showed that EZH2 could increase the mRNA expression of DDX11, which was significantly attenuated by the knockdown of E2F1.

As expected, DDX11 mRNA was upregulated by EZH2 overexpression, which was abolished by the knockdown of E2F1 (XREF_FIG).

In HCC cells, knockdown of E2F1 significantly decreased the mRNA expression of EZH2.

This manifests DDX11 was not required for the E2F1 mediated EZH2 regulation.

However, the expression of p53 and MDM2 remained unchanged (XREF_FIG), which may suggest a p53 independent manner of DDX11 mediated p21 alteration.
