Comparison of lipid metabolism genes and their expression levels between KSA and USA breast cancer data. Description: Gene expression data from both the present study as well data from Hawthorn et al were imported into IPA. Significantly altered biological functions and pathways were obtained individually for each study. From the differentially expressed genes, those involved in lipid metabolism were linked, and their expression levels were overlaid on to the network. a. KSA data; b. USA data. Molecules colored with green denote downregulation and white denote no change in expression compared to their respective healthy normal.
