Overexpressed HDAC4 is associated with poor survival and promotes tumor progression in esophageal carcinoma
Figure 3. HDAC4 knockdown induces G1/S arrest in EC cells. (A and C) Flow cytometry analysis of indicated EC cells transfected with HDAC4-specific siRNAs or a control siRNA; G1-phase cells are significantly increased while S-phase cells are reduced in HDAC4 knockdown (B) KYSE30 and (D) EC/CUHK1 cells, * P <0.05; (E) HDAC4 down-regulation increases the expression of p21 and p27 proteins while reduces pRb, CDK2 and CDK4 in EC cells.
