Research Interests and Laboratory Features

The research core of our laboratory is established at the intersection of Chronohepatology and Genome Content Transition. Our team is dedicated to deciphering a fundamental scientific puzzle: How does the liver, the body's most critical metabolic and circadian organ, modulate the molecular switches of polyploidization and polyploidy reversal to dynamically adapt under physiological and pathological states when confronted with circadian clock disruption and environmental stress shocks? Based on our team's published series of studies, our research can be systematically deconstructed into the following four major tracks to decode the triangular network of circadian rhythms, genome transition, and preneoplastic lesions

1. Molecular Regulatory Mechanisms of the Circadian Clock on Hepatic Polyploidy

Under normal physiological conditions, the mammalian liver exhibits a unique and prevalent phenomenon known as polyploidy (the presence of more than two sets of homologous chromosomes within a single cell nucleus). In our first paper (Nature Communications, 2017), our team linked the biological clock with this specific cellular trait for the first time, discovering that the circadian clock serves as a master timer controlling the developmental progression of hepatocyte polyploidization. Our research demonstrated that mutations in the core clock gene Periods, or circadian disturbances induced by environmental stress, directly disrupt the 24-hour dynamic oscillation of the downstream Mkp1-Erk1/2 signaling pathway. This rhythmic dysregulation leads to cytokinesis failure during hepatocyte mitosis, thereby abnormally accelerating the transformation of normal diploid or low-ploidy hepatocytes into hyperpolyploid cells.

2. Hepatocyte "Hyperpolyploidization" as an Initiator of Hepatic Preneoplastic Lesions

The academic community historically considered polyploidization a protective mechanism against liver aging or metabolic stress. However, in our second paper (Nature Communications, 2021), our team proposed a subversive translational medicine perspective: Excessive hepatocyte polyploidization (hyperpolyploidization) is essentially the onset of preneoplastic lesions. Utilizing animal models, we demonstrated that when hepatocytes are pushed toward hyperpolyploidy by chronic inflammation or circadian dysregulation, the excessive genomic content exposes the cells to extreme chromosomal instability (CIN) during chromosome segregation. Subsequently, when these cells undergo polyploidy reversal to revert to a lower ploidy state, the process triggers a genomic "reshuffling," which directly drives malignant transformation and culminates in the formation of hepatic preneoplastic lesions.

3. Whole-Nucleus Elimination Regulating the Polyploidy Reversal Defense Line to Suppress Tumorigenesis

Our laboratory discovered that when mice are exposed to genotoxic environmental stress, the nuclear number status of their hepatocytes alters. This change represents a peculiar phenomenon of whole-nucleus elimination achieved through the removal of specific nuclei. We found that whole-nucleus elimination can be viewed as a cellular self-rescue and defense mechanism when facing devastating DNA damage. It directly packages and eliminates highly mutated, potentially tumorigenic nuclear materials, preventing these cancer-driving genetic mutations from entering the subsequent mitosis, thereby maintaining the genome integrity of the entire liver tissue. Fundamentally, it serves as a massive form of selective nucleophagy (macro-nucleophagy), acting as a critical defensive player and the ultimate genomic janitor in tumor suppression and anticancer fields.

4. The Practice of "Chronopharmacology" and Targeted Precision Medicine

In collaboration with Professor Huatao Chen from Northwest A&F University, our laboratory co-developed "CircaVal," a big data and multi-omics circadian rhythm analysis platform. This platform executes precise calculations using a specialized rhythmicity algorithm (Rhythmicity Score Explorer) tailored for high-throughput sequencing data (such as RNA-seq, Nascent-seq/nascent transcriptome, and Ribo-seq/translatome). By interfacing with the Chang Gung Research Database (CGRD) and patient tissue specimens, we constructed Taiwan’s first "Post-Viral HBV Temporal Targeted Medicine Precision Prediction Platform," which enables the decoding of temporal targets showing 24-hour dynamic fluctuations amid vast clinical datasets.Furthermore, we develop chronotherapy strategies to evaluate the optimal "time window" within a day for administering targeted anticancer drugs and anti-inflammatory inhibitors. This approach aligns with the rhythmicity of hepatic clock genes to maximize the eradication of preneoplastic cells while utilizing time differentials to perfectly shield normal hepatocyte mitochondria from drug toxicities, seamlessly bridging clinical big data with fundamental molecular biology experiments.
