The increasing use of plastics has elevated the risk of exposure to environmental pollutants such as plasticisers in the general population, making it necessary to understand the possible long term health consequences of the same. In this study we aim to understand how DEHP affects the gene expression in mice models and if it causes disruptions to its cellular pathways. Two datasets, GSE18564 and GSE14920 comprising of 15 and 60 samples respectively were downloaded from GEO database for analysis. Quality control checks were done using Principal Component Analysis and quantile normalisation. Differentially expressed genes were found using LIMMA model, following which only top 20 genes were selected for pathway analysis using KEGG and Gene Ontology. DEHP was found to be associated with chemical carcinogenesis, including negative regulation of extrinsic apoptotic signaling pathway and fatty acid metabolism. Furthermore, it seems likely that PPAR-alpha might play a key role in DEHP related metabolic disruption. Further studies are required to better elucidate the effect of DEHP on individual metabolic pathway implicated in this thesis.
