RESEARCH FOCUS

Investigate the role of the microbiota in digestive system cancers, metabolic syndrome, and rare metabolic disorders, as well as their pathogenic mechanisms. Develop microbiota-centered biomarkers and intervention strategies.
Using the microbiota as the core, conduct multiomics and phenomics research on the mentioned diseases and their sub-healthy populations. Establish their digital avatars for disease prediction and prevention.
The research mentioned above aims to develop a precision health research and development ecosystem that encompasses industry, academia, and research. This will expand the value of research and innovation from basic to clinical, from laboratory to patient care in hospital wards, and from hospitals to the community.

January 19, 2026Assistant Professor Cheng-Yen Kao and othersEmergence of conjugative metallo-β-lactamase-encoding plasmids in the Klebsiella pneumoniae species complex: First identification of IMP-8-MCR-9.1 in K. quasipneumoniae and VIM-1 in K. variicola in TaiwanAmong CRKpSC isolates, blaKPC was the most common (20.1%), followed by blaOXA-48 (3.4%), while blaIMP, blaNDM, and blaVIM were quite rare (≤1%), and only a very few strains carried multiple genes simultaneously. Only a few Kq and Kv strains carried metallo-β-lactamase genes, with pNCKUH114–1 plasmid carrying blaIMP-8 and mcr-9.1, and pNTUH73–1 carrying blaVIM-1, showing limited similarity to plasmids known in the database. These two plasmids could only be transferred to E. coli EC359, and under experimental conditions, they did not increase its pathogenicity to larvae.Journal of Infection and Public Health4
February 3, 2026Assistant Professor Cheng-Yen Kao and othersA combined genetic and phenotypic marker approach enables precise detection of hypervirulent Klebsiella pneumoniae and reveals associated traits of capsule overproduction and tellurite resistanceThis study integrated gene and phenotypic analysis to compare carbapenem resistance and liver abscess-associated Klebsiella pneumoniae strains. It found that five virulence genes (peg-344, iroB, iucA, prmpA, prmpA2) combined with a string test could effectively identify highly virulent strains (hvKp). Results showed that strains carrying all five genes, regardless of string test positivity, exhibited high virulence and capsule production. The LAKp group showed the most significant lethality and capsule formation, while CRcKp, lacking these genes, exhibited the lowest virulence. Long-term monitoring also revealed that the proportion of blood isolates carrying the five virulence markers was higher than that of urine isolates, indicating that these biomarkers can help improve the clinical detection and risk assessment of hvKp.Microbiol Spectr3.8
February 27, 2026Ting-Ting Chang and othersInhibition of CCL4 prevents renal inflammation and fibrosis in acute kidney injuryThis study explored the role of the chemokine CCL4 in acute kidney injury and found that inhibiting CCL4 can reduce renal inflammation and subsequent fibrosis, suggesting that CCL4 may be a potential therapeutic target for acute kidney injury complicated by renal fibrosis.Clinical Science7.7
March 18, 2026Ting-Ting Chang and othersCCL7 suppression alleviates vascular injury by blocking the CCR5/STAT1 signaling pathway in chronic kidney diseaseThis study investigated the role of the inflammatory chemokine CCL7 in the development of peripheral artery disease in chronic kidney disease (CKD). The study found elevated CCL7 concentrations in the blood of CKD mice, accompanied by decreased blood flow in ischemic limbs and delayed wound healing. Inhibition or knockout of CCL7 promoted angiogenesis, increased capillary density, and improved blood flow and tissue repair, demonstrating a negative regulatory effect on angiogenesis. Further mechanistic studies indicated that CCL7 affects endothelial cell function by regulating the CCR5/STAT signaling pathway, thus potentially becoming an important therapeutic target for CKD-related vascular complications.Life Sciences5.1
March 24, 2026Li-Ling Wu and othersNfil3 integrates circadian rhythm and microbial metabolite signaling to maintain gut-liver immune-metabolic homeostasis under high-fat diet stressThese results support Nfil3 as a key regulatory node linking the functional potential of the gut microbiota to immune and metabolic responses in metabolically associated fatty liver disease (MASLD). Although currently in preclinical research, this study provides a mechanistic framework illustrating how gut microbiota-related metabolic reprogramming influences host immune and metabolic homeostasis. Future research, combining circadian rhythm and metabolite hierarchy studies with human interventional trials, is needed to clarify the clinical significance of the microbiota-Nfil3 axis.J Transl Med9.7
April 2026Assistant Professor Cheng-Yen Kao and othersMultidrug-Resistant Klebsiella pneumoniae in a Pediatric ICU: Emergence of Newly Identified ST7120 and the First Report of ST792 in TaiwanThis study describes a year-long cluster of multidrug-resistant Klebsiella pneumoniae in a pediatric intensive care unit from September 2021 to August 2022, identifying a novel variant, ST7120, and the first case of ST792 in Taiwan, both associated with long-term colonization and invasive infection. Two of the infections originated from carbapenem-resistant ST7120 (one resulting in death), while the other was an ESBL-producing ST792 that led to severe neurological sequelae. This demonstrates that molecular epidemiological surveillance can be helpful in the early detection and containment of nosocomial infection outbreaks.New Microbes New Infect5.4
April 17, 2026Professor Chun-Ying Wu and othersRapid electrochemical profiling of fecal short chain acids using esterification/dissociation fingerprints and artificial neural networksThis study developed a rapid and inexpensive method for detecting short-chain fatty acids (SCFAs) in human feces, and incorporated artificial intelligence to improve analytical accuracy. The study found that this method can accurately measure important metabolites such as propionic acid and butyric acid even in complex fecal samples, with results almost identical to traditional GC-MS detection. Due to its fast detection speed and low equipment cost, it has the potential for future applications in large-scale health screening and long-term gut health monitoring.Biosensors5.6
May 8, 2026Professor Chun-Ying Wu and othersIntratumoral microbial networks as biomarkers for second primary oral cancer risk in esophageal squamous cell carcinomaThis study analyzed the microbial community of tumor samples from 28 patients with esophageal squamous cell carcinoma (8 of whom also had a second primary oral cancer). The results showed that the intratumoral microbial network could effectively distinguish whether a second primary oral cancer was present. Among them, the microbial community module with Prevotella pallens and P. scopos as its core was closely related to the risk of oral cancer, indicating that the intratumoral microbial community can serve as a biomarker for predicting the risk of a second primary cancer.Sci Rep4.9

Quantitative assessment of cDDD (cumulative defined daily dose) can objectively reflect treatment intensity and predict clinical outcomes. This approach helps advance staging-guided and precision treatment strategies for IgG4-related diseases.Rheumatology4.7
