Lab & Research Interest

My laboratory has devoted extensive efforts to the mechanistic understanding of various aspects of mammalian gene regulation, particularly focusing on roles of RNA editing and regulatory RNAs:

Decoding the hidden message of RNA editome. We are one of the earliest groups that exploit the high-throughput sequencing approach in demarcating the widespread A-to-I RNA editing events, which constitute an integral step in generating primate transcriptome diversity. We established a computational pipeline to extensively archive transcriptome-wide RNA editing events (Nat. Biotechnol. 2012, 30:253), which paved the way for large-scale studies and for advancing our understanding of this gene regulatory process in human. As a proof of principle, we reported quantitative tissue-specific RNA editome profiles for rhesus macaque, a close relative of human (PLoS Genet. 2014, 10:e1004274), and more recently a new mechanism for the functionality of RNA editing – a crosstalk with piRNA biogenesis – by deciphering RNA editome across the piRNA species (Mol Biol Evol. 2015, 32:3143). The expression of these editing-bearing piRNA variants (epiRNAs) illustrates the contribution of primate RNA editing to the diversification of the piRNA repertoire. In a more functional context, ADAR1 was found to mediate 3’ UTR editing and expression control of antiapoptosis genes, thus fine-tuning cellular apoptosis response (Cell Death and Disease 2017, 8:e2833). More recently, we reported a functional coordination between ADAR1 and an antisense non-coding RNA in the regulation of HIF-1α expression, with significant implications in maintaining robust hypoxia signaling and controlling tumor progression (EMBO Reports 2019, 20:e47107).

“Non-coding” RNAs with big impact in cell biology. Regulatory RNAs such as microRNAs and lncRNAs are known to impart post-transcriptional regulation to critical factors in various cellular signaling and functional networks. Our recent works have broadened the realm of ncRNA biology by functionally delineating several microRNA-centric regulatory axes: 1) Our studies uncovered two distinct circuitries that underlie proper progression of skeletal myogenesis – the miR-546-Mybbp1a (EMBO J. 2012, 31:1739) and miR-1/206-ADAR1 (Cell Death Differ. 2014, 21:707), both of which contribute to the scheduled gene program transitions. 2) We also discovered that nucleolar size and rRNA pool in Caenorhabditis elegans is under the tight control of a novel genetic cascade, let-7-ncl-1-fib-1 (PLos Genet. 2015, 11:e1005580). 3) A miR-31-5p-ACOX1-PGE2 pathway was delineated that underpins overall cellular lipidome profiles as well as the migratory and invasive abilities of oral cancer cells (Theranostics 2018, 8:486). 4) Non-coding transcriptome profiling of oral carcinoma revealed a novel pro-tumor circular RNA circFLNB that mediates growth-regulating transcriptional response (Cells 2020, 9:1868), and the lncRNA HOXA10-AS that serves as a modular scaffold for TP63 mRNA processing to promote cancer growth and metastasis (Cell Death and Disease, 2022, 13:629).

Deep reading of the cancer-associated biosignatures. As a managing faculty member of the NGS Core Lab at Chang Gung University, I have been leading research efforts in the establishment of deep sequencing platforms and data analysis workflows in the various cancer genomic and transcriptomic studies. We have identified in advanced oral squamous cell carcinoma a mutation-based prognostic gene signature associated with cytidine deaminase APOBEC (Nat Commun. 2017, 8:465). To address the bioinformatics need of cancer functional genomics studies, we also developed a web-based analytic tool, circlncRNAnet, for mapping functional networks of long or circular forms of non-coding RNAs (GigaScience 2018, 7:1).
