Recently, the epigenetic modifications have been recognized as a regulator of gene expression in various cancers. EZH2 gene is one the most important component of the PRC2 complex. Overexpression of EZH2 was identified in multiple cancers that considered more attractive the EZH2 role as an oncogene. Some studies report that EZH2 contributes to various aspects of colorectal cancer (CRC). However...
Enhancer of zeste homolog 2 (EZH2) is a key epigenetic regulator that catalyzes the trimethylation of H3K27 and is modulated by post-translational modifications (PTMs). However, the precise regulation of EZH2 PTMs remains elusive. We, herein, report that EZH2 is acetylated by acetyltransferase P300/CBP-associated factor (PCAF) and is deacetylated by deacetylase SIRT1. We identified that PCAF in...
The polycomb group protein enhancer of zeste homologue 2 (EZH2), which has histone methyltransferase (HMT) activity, is overexpressed in malignant tumours. However, the role of EZH2 in colorectal cancer (CRC) invasion is little known. Here we investigated the clinical significance, biological effects, and mechanisms of EZH2 signalling. Knockdown of EZH2 significantly reduced cell invasion and s...
The role of enhancer of zeste homolog 2 (EZH2) in cancer is complex and may vary depending on the cellular context. We found that EZH2 is aberrantly overexpressed in the majority of natural killer/T-cell lymphoma (NKTL), an aggressive lymphoid malignancy with very poor prognosis. We show that EZH2 upregulation is mediated by MYC-induced repression of its regulatory micro RNAs and EZH2 exerts on...

We found that EZH2 is aberrantly overexpressed in the majority of natural killer / T-cell lymphoma (NKTL), an aggressive lymphoid malignancy with very poor prognosis. We show that EZH2 upregulation is mediated by MYC-induced repression of its regulatory miRNAs and EZH2 exerts oncogenic properties in NKTL. Ecto...
INTRODUCTION Although enhancer of zeste homolog 2 (EZH2) has been associated with both non-small cell and small-cell lung cancers (SCLCs), current observations suggest different mechanisms of EZH2 activation and overexpression in these lung cancer types. Globally, SCLC kills 200,000 people yearly. New clinical approaches for SCLC treatment are required to improve the poor survival rate. Given t...
Enhancer of zeste homolog 2 (EZH2) trimethylates histone H3 Lys 27 and plays key roles in a variety of biological processes. Stability of spindle assembly checkpoint protein BubR1 is essential for mitosis in somatic cells and for meiosis in oocytes. However, the role of EZH2 in oocyte meiotic maturation was unknown. Here, we presented a mechanism underlying EZH2 control of BubR1 stability in th...
Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy in the United States. EZH2 silences gene expression through trimethylating lysine 27 on histone H3 (H3K27Me3). EZH2 is often overexpressed in EOC and has been suggested as a target for EOC intervention. However, EZH2 target genes in EOC remain poorly understood. Here, we mapped the genomic loci occupied by EZH2/H3K27...
UNLABELLED As a master regulator of chromatin function, the lysine methyltransferase EZH2 orchestrates transcriptional silencing of developmental gene networks. Overexpression of EZH2 is commonly observed in human epithelial cancers, such as non-small cell lung carcinoma (NSCLC), yet definitive demonstration of malignant transformation by deregulated EZH2 remains elusive. Here, we demonstrate t...
Background: As critical regulators, lncRNAs have attracted attention from researchers for diagnostic, prognostic, and therapeutic purposes in human carcinogenesis via interfering with mRNAs such as EZH2. Nevertheless, the potent roles and molecular mechanisms of these RNAs in CRC are not clearly known. Methods: In this study, the tissue expressions of lncRNA MINCR and EZH2 mRNA between colorect...
