2.Representative Research Achievements
1) Dr. Jing Xiong mapped the landscape of the transcriptomic reprogramming during metabolic liver injury, especially non-alcoholic fatty liver disease and hepatocellular carcinoma. Her group revealed that a key nuclear factor hnRNPU
mediated NASH pathogenesis. They further investigated a target gene of hnRNPU, TrkB-T1, which aggravated metabolic injury of hepatocytes and therefore promoted NASH progression. (Hepatology, 2020; Acta Pharm Sin B, 2022)
2) Focusing on the liver adverse reactions caused by drugs, they concealed the underlying mechanisms of drug-associated liver metabolic disorders from clinical,animal model and cellular perspectives, providing supporting evidence and precedented insights for the clinical rational drug usage. (Acta Pharmacol Sin,2018; Int J Biochem Cell Bio, 2014)
3) They uncovered the molecular mechanisms of the transcriptional regulation for drug metabolizing enzymes and transporters by focusing on the transcription factors, metabolic nuclear receptors and their target genes, and contributed to the discovery and validation of the potential drug targets for the avoidance and alleviation of drug-induced liver injury, and for the reversal of multi-drug resistance. (Br J Pharmacol, 2017; Toxicology, 2020; Eur J Pharm Sci, 2017; Cells, 2021; Neoplasia, 2022)
Dr. Jing Xiong obtained her PhD degree at China Pharmaceutical University in a joint PHD program with Mayo Clinic, received a postdoc training at University of Michigan and became a professor at China Pharmaceutical University since 2020. Her group mainly focuses on three aspects regarding liver pathophysiology and drug intervention. Firstly, investigate mechanisms underlying the pathogenesis of metabolic liver diseases, including non-alcoholic fatty liver disease and hepatocellular carcinoma. Secondly, design and develop drugs targeting metabolic homeostasis for the therapy of liver diseases. Thirdly, delineate the mechanisms that regulate the transcription of drug metabolizing enzymes and drug transporters, contributing to the discovery and validation of the potential drug targets for liver injury and reversal of multi-drug resistance.
