During my Ph.D. training (2016-2021), I became very interested in cellular reprogramming and have been working on this area through statistic model. Mounting important scientific problems are involved in cellular reprogramming, such as cell differentiation, tumor generation, and disease occurrence. I have completed several works through statistics, optimization, and graphical model methods using multi-omics data such as RNA-seq, ATAC-seq, ChIP-seq, and HiC. I investigated the combination of transcription factors by set cover problem, which identified safeguard TFs systematically. This work tried to throw light on the mechanism of cellular reprogramming from a macro perspective. I also focused on several specific cases. ERG fusion always occurs along with the loss of basal cells and the increasing of luminal cells. I verified the reprogramming from basal to luminal induced by ERG overexpression. I found ERG represses the basal marker Trp63 by binding the enhancers and then regulates the expression of Trp63 by chromatin interaction of enhancers and the promoter of Trp63. I further constructed the regulatory network in the context of wild type and ERG overexpression, comparing them systematically by identifying the regulatory modules. Other cases are the characteristic subtypes of pancreatic carcinoma and hepatocellular carcinoma, which can be taken as the mutual transformation from one subtype to another. I linked the subtype and drug response by statistics method which would guide clinical treatment.
Research
My research interest is to build optimizational and statistical model about cell reprogramming and cell fate determination by integrating multi-omics data.
