Long term goals of the Hwang-Verslues laboratory are to decipher the links among circadian rhythm, core clock gene functions and stem cell (SC) fate/characteristics in tissue development and disease progression.

Program 1 is to use mice and cell cultures as models to investigate whether circadian rhythms or core clock genes contribute to intestinal SC (ISC) fate determination, and how the circadian clocks in the brain and the intestine coordinate with each other to regulate ISC fate. We also aim to understand how heterogeneous cell types in the intestine synchronize their circadian rhythms to generate a SC niche and how the circadian-SC relationship influences disease development, such as chronic inflammation and cancer. By mechanistically linking circadian regulation to SC fate and function, we will not only gain fundamental knowledge in chronobiology but also provide new strategies or targets for disease prevention and treatment.

Program 2 focuses on regulation of Period 2 (PER2), a core circadian regulatory factor, in both normal and cancerous condition. In peripheral tissues, the circadian genes have tissue specific functions and play important roles in tissue specific responses to the circadian environment (1-3). We previously found that PER2 acted as a tumor suppressor in normal breast cells (4). Loss of the PER2 allowed activation of EMT gene expression, enhancement of invasion and elevation of breast cancer stem cell (CSC) prevalence (4). This new role of PER2 may be particularly relevant in understanding the association of disrupted circadian rhythm due to both external or intrinsic factors and increased cancer incidence that has been observed in epidemiological studies (5-7). Despite the fact that PER2 exhibits tumor suppressor function and is downregulated in breast cancer cells, it is not clear how PER2 suppression occurs in pre-cancerous mammary epithelial cells. We found that IL-6 and CCL2 from the inflammatory microenvironment suppressed PER2 expression in phenotypic normal breast epithelial cells to promote cancer stemness and tumorigenic potential (8). Reduced PER2 expression was observed over a time scale of hours to weeks following IL-6/CCL2 stimulation. This suggested that PER2 suppression occurs in the early stage of interaction between an inflammatory microenvironment and normal breast epithelial cells. These data show that PER2 repression contributes to breast tumorigenesis and illustrate a new mechanism by which mammary cells interact with a cancerous microenvironment.

PER2 is important for timely inhibition of circadian gene expression and reactivation of the transcription-translation feedback loop (TTFL) that drives circadian rhythms. A phosphoswitch between two competing PER2 phosphorylation (S662 versus S480) sites is known to control PER2 stability, localization and transcriptional repression activity. However, the mechanisms controlling this switch (ie: which PER2 site gets phosphorylated by CK1) have remained unknown. We show for the first time the importance of SUMOylation in controlling activity of the core circadian clock protein PER2. This SUMOylation may work upstream of and controls the critical PER2 phosphoswitch. The effect of PER2 SUMOylation during tumorigenesis is currently under investigation (Chen LC et al. bioRxiv doi:

Program 3 is to identify new factors driving cancer metastasis. Metastasis is the major cause of cancer death. Circulating tumor cells (CTCs) is particularly associated with colonization of distant organs and poor prognosis. We found that expression of cell adhesion molecule Desmoglein2 (DSG2) is correlated with poor prognosis and recurrence risk in breast cancer patients. High DSG2 expression promoted tumor growth, increased clustered CTCs and facilitated distant organ colonization. When hypoxia occurred, HIF1α directly bound and recruited polycomb repressive complex 2 components to suppress the DSG2 promoter activity. Downregulation of DSG2 led to elevated EMT and enhanced invasion ability of cancer cells, thus allowing cells to detach from the primary tumor and undergo intravasation. Once hypoxic stress was released in the vascular system and lung tissues, DSG2 was de-repressed allowing CTCs to colonize in distant organs. Together, our results demonstrated the role of DSG2 expression in breast cancer metastasis and revealed a new molecular mechanism by which hypoxia drives metastasis.
