The main focus of the Hwang-Verslues laboratory is on cancer and circadian biology. We have been pursuing three research aims: 1. Identify key factors critical for cancer initiation, metastasis and recurrence, 2. Determine the significance of circadian and core clock gene regulation in tissue homeostasis and stress response, and 3. Investigate the interplay between circadian dysregulation and cancer progression. For each of these research aims, our accomplishments to date are summarized as below.

Research aim 1: Key factors driving tumorigenesis and cancer metastasis and recurrence
Breast cancer: Interplay between desmoglein2 and hypoxia controls metastasis in breast cancer [Chang PH et al, PNAS, 2021 (PMID: 33431674)]. We found that high DSG2 expression is correlated with poor prognosis and recurrence risk in breast cancer patients. DSG2 promotes tumor growth, increases CTC clusters and facilitates distant organ colonization. Dynamic repression and de-repression of DSG2 in response to changing levels of oxygen is needed to allow cells to detach from hypoxic primary tumor, invade in circulation and later colonize in oxygen rich distal organs. Also, this is the first report demonstrating a transcriptional suppression function of HIF-1α on an oncogenic factor. These findings demonstrate the importance of DSG2 in all stages of breast cancer metastasis.

Ovarian cancer: The dual-function RNA binding protein MEX3A mediates p53 degradation to prevent ferroptosis and facilitate ovarian cancer tumorigenesis [Wang CK et al., in revision]. We found that MEX3A, which is a dual-function protein containing a RING finger domain and an RNA binding domain, is correlated with poor survival in OC. Further investigation revealed that MEX3A upregulation is crucial for tumorigenesis in ovarian cancer (OC) expressing wild-type (WT) p53 protein [e.g., ovarian clear cell carcinoma (OCCC) and endometrioid carcinoma (EC)]. MEX3A overexpression enhances tumorigenic activity; whereas, depletion of MEX3A reduces cell survival and proliferative ability, inhibits tumor growth and prolongs survival. MEX3A depletion does not alter p53 mRNA level but does increase the protein stability of WT p53. MEX3A-mediated p53 protein degradation is crucial to prevent ferroptosis and enhance tumorigenesis. Identification of MEX3A-WT p53-ferroptosis as a pathway determining clinical severity of ovarian tumorigenesis provides an opportunity to develop new treatment strategies for cases of OC with WT p53. [supported by Academia Sinica (AS-SUMMIT-108, -109) and the Ministry of Science and Technology (MOST111-2314-B-001-012-)].
We are currently investigating additional MEX3A functions in OC metastasis.

Research Aim 2: Circadian and core clock gene regulation in tissue homeostasis and stress response
Core circadian transcription factor BMAL1 and RNA-binding protein MEX3A co-regulate intestinal stem cell homeostasis and stress response. (Cheng LT and Chang FP et al. This study is currently under preparation for submission. bioRxiv doi: We found that the core clock gene BMAL1 participates in regulating intestinal stem cell (ISC) homeostasis. BMAL1 transcriptionally regulates oscillating expression of two essential ISC genes, Mex3a and Lgr5, in the crypt-based ISCs. Depletion of BMAL1 in the Lgr5+ ISCs perturbed lineage specific gene expression in the intestinal epithelium. BMAL1 appears to be essential for the intestinal epithelium to cope with stress. 5-FU delivery at the time of day when Lgr5 expression peaked increased apoptosis and inhibited intestinal epithelial cell proliferation. In contrast, apoptosis was not detectable if 5-FU was delivered when Lgr5 expression was lowest. These results provide mechanistic explanation of how chronotherapy can reduce 5-FU side effects.

We are currently investigating how BMAL1 participates in intestinal stress response.

Research aim 3: Interplay between circadian and cancer
PER2 suppression enhances tumorigenic potential and EMT in breast cancer. I previously discovered that core clock gene PER2 inhibits invasion and cancer stemness in breast cells [Hwang-Verslues et al., PNAS, 2013 (PMID: 23836662)]. Recently, we found that IL-6 and CCL2 in the inflammatory microenvironment suppressed expression of PER2 to increase tumorigenic potential in breast epithelial cells. These data show a new mechanism by which mammary cells interact with a cancerous microenvironment via PER2 [Yu CW et al, BBA-GRM, 2018 (PMID: 30343691)]. We also found that PER2 can be SUMOylated to modulate its transcriptional repressor function and protein stability. Thus, PER2 SUMOylation is also likely to affect the tumor suppressor functions of PER2 as well as PER2 clock function. [Chen et al, Scientific Reports, 2021 (PMID:342573720)].

We are currently investigating BMAL and PER2 functions in ovarian cancer.
