Figure 6 shows associations with a p-value < 0.01 (either t-test or Fisher’s exact test), in which the genes linked to assays statistically associated with the three rat liver lesion categories, as well as human disease categories assigned through the Online Mendelian Inheritance in Man (OMIM) database (Goh et al. 2007). PPARG, HMGCS2, and CCL2 are all associated with preneoplastic and neoplastic levels in the liver disease progression, and PPARA is additionally associated with neoplastic lesions. The gene discussed is PPARA; the disease is liver disorder.
