Interests in Research

Jia-Ching Shieh is interested in how genetic, epigenetic, and environmental factors get involved in a variety of human diseases, which is in concert with the subjects of his teaching. His main research focuses presently addresses the mechanism underlying morphological plasticity, key to switch of commensalism-to-pathogenesis, of the opportunistic human fungal pathogen Candida albicans, which is significant in both biology and medicine. Unprecedentedly, his team found that C. albicans CDC4 (CaCDC4) and CDC7 (CaCDC7) suppress yeast-to-hypha transition, contrasting to their evolutionarily conserved roles in the G1-to-S transition and initiating DNA replication of the mitotic cell cycle, respectively. His studies revealed the cross-talk between morphogenesis and stress and nutrient responses, environmental cues, and the role of epigenetic regulation in morphological plasticity and are under further investigation using classical approaches of genetics, molecular biology, cell biology and biochemistry incorporated with the cutting edge technologies of functional genomics, proteomics, and epigenomics. Additionally, to overcome C. albicans being an incomplete sexual cycle diploid with a non-canonical codon usage, his team established novel platforms such as gene deletion, conditional gene expression, bimolecular fluorescence complementation (BiFC), and E. coli-based ubiquitination, which reinforce revealing unique genes involved in morphogenesis and other virulence-related genes and their functional analysis. These platforms are available and used by dozen of research teams at home and abroad
