Research

(I) Virus-Host interaction: Epigenetic regulation and Cancer

Epigenetic regulation includes: (1) DNA methylation; (2) Histone methylation and (3) Long non-coding RNAs (LncRNAs).

By using oncogenic herpesvirus KSHV as a model, we studied the tumorigenic role of JMJD2A, the first identified histone trimethyl demethylase,

and its own modification in epigenetic regulation. We found that JMJD2A is important for maintain low levels of H3K9me3,

a favorable chromatin environment to execute rapid transcriptional reprograming. JMJD2A was targeted and sumoylated by KSHV K-bZIP,

a viral SUMO E3 ligase. Sumoylation is essential for chromatin binding and in vivo dementylation function of JMJD2A.

Our study also showed the role of JMJD2A in regulating IFN response and how virus against human immune system through targeting JMJD2A.

Nowadays, we use KSHV as a model to identify novel KSHV reactivation associated long non-coding RNAs (lncRNAs),

a newly emerged epigenetic regulator, and elucidate their tumorigenic role.

 

 

 

(II) Epigenetic regulation of Prostate Cancer

I further extend our epigenetic study to prostate cancer (PCa) research. PCa is a leading cancer affecting male population. 
Thought it can be successful treated by androgen deprivation therapy (ADT), unfortunately, 
hormone refractory prostate cancer (HRPC) eventually relapsed within few years after successful treatment. 
Thought 2nd generation of AR antagonist was developed and used for treating HRPC, it induced neuroendocrine differentiation (NED) of PCa cells.
This emerging type of
PCa, so-called NEPC, is highly metastatic and chemoresistant.
We identified
repressor element-1 (RE-1) silencing transcription factor (REST) as a key regulator for. Following this observation,
we
also demonstrated that long-term REST knockdown not only induce NED but also enhanced cell stemness through epigenetic regulation of Twist1 and CD44.
In addition, we identified MAOA,
a decision maker of apoptosis (inhibition) and autophagy (activation), as a novel REST target gene.
It involves in mediating mitophagy activation during NED of PCa cells. Nowadays,
we use
NED as a model and identified many novel NED regulatory lncRNAs, including HOTAIR.

 

 

(III) Cancer Immunology

Emerging evidence showed that microenvironment shaped by pro- and anti-inflammatory types of macrophages contribute to not only host defense, but also cancer progression.
We found that cancer stem cells (CSCs), without affect macrophage phenotype, induce M1 macrophages producing NED-related cytokines.
Integrating transcriptome profiling in combine with mass spectrometry metabolites analysis reveals the contribution of glycolysis pathway in NED-related cytokines production.
Importantly, CSC-educated M1 macrophages induced NED of cancer cells, thereby shifting carcinoma reprograming toward a neuroendocrine (NE) fate.
In tumor tissues, NE marker CgA expression is associated with M1, but not M2, marker.
These findings offer therapeutic opportunities of using immunotherapy to prevent the induction of a more malignant cancer phenotype.
