Developing novel network-based methods to predict drug effects on diseases [Sep. 2013 – Present]
PDOD: Predict drugs having opposite effects on diseases states with ‘effect type’ such as ‘activation’ or ‘inhibition’ in biological networks and altered states of gene expressions in diseases (Using KEGG pathways, DrugBank, CTD, GEO).
CODA: Construct a tissue-specific network with protein expression data and literature and predict effects of drugs on diseases with the network. Distinct from other previous tissue-specific networks, our constructed network includes GO terms and diseases with anatomical context and intercellular associations (Using KEGG pathways, BioGRID, TRANSFAC, GO, EndoNet, CTD, PubMed, PhenoGO, HPA).
HIDEEP: Identify hormones affecting drugs with hormone-receptor relations, drug-target interactions, and protein-protein interactions (Using KEGG, BioGRID, DrugBank, EndoNet).
Identifying somatic mutations with sequencing data [Jan. 2017 – Present]
Calling somatic mutations: Develop a pipeline to identify putative somatic mutations from brain samples without matched control.
eQTL analysis with SNP chip data and RNA sequencing data [Jan. 2012 – Jan.2013]
eQTL analysis: Identify associations between mutations and gene expressions by eQTL analysis in schizophrenia patients (Stanley database).
Analyze transcriptome in whole brain regions [Sep. 2010 – Aug. 2011]
Microarray data analysis: Analyze transcriptome patterns among whole brain regions using gene expression data (Allen Brain Atlas).
