A Three Stage Integrative Pathway Search (TIPS©) framework to identify toxicity relevant genes and pathways

Abstract: Background: The ability to obtain profiles of gene expressions, proteins and metabolites with the advent of high throughput technologies has advanced the study of pathway and network reconstruction. Genome-wide network reconstruction requires either interaction measurements or large amount of perturbation data, often not available for mammalian cell systems. To overcome these shortcomings, we developed a Three Stage Integrative Pathway Search (TIPS © ) approach to reconstruct context-specific active pathways i… Show more

“…The reconstructed network was perturbed to identify i) which genes, when perturbed, had an impact on altering the cytotoxic phenotype in the palmitate cultures, and ii) how perturbing a gene (node) affected the other genes in the network. More details can be found in our published paper [6]. TIPS © was further extended to identify genes relevant to multiple cellular responses, e.g., multiple metabolites, in a separate study [11].…”

“…While biology-driven interpretations have been more commonly reported, data-driven techniques have been utilized to study diverse areas, such as hepatocellular metabolism77, the unique effects of anti-inflammatory compounds on macrophage cells78, and the identification of regulatory metabolites and gene transcription in glucosinolate and anthocyanin biosynthesis79. Another comprehensive example is a ‘pharmaco-metabolomic’ approach in which pre-dose metabolite profiles of urine and chemometrics were used to predict toxicity responses to acetaminophen in an in vivo rat model80.…”
