Figure 2. FOXA1 and HNF4A activate independent liver- and intestine-specific genes.
(A) The number of tissue-specific genes predicted from the hypergeometric distribution to be activated by FOXA1 compared to the number actually activated. Liver enrichment (p<10–4) is significant. There are 242 total liver-enriched genes. (B) The number of tissue-specific genes predicted from the hypergeometric distribution to be activated by HNF4A compared to the number actually activated. Liver- (p<10–8) and intestine enrichment (p<10–15) are significant. There are 242 total liver-enriched genes and 122 total intestine-enriched genes. (C) 242 liver genes characterized as activated by Foxa1, HNF4A, both, or neither. (D) 122 intestine genes characterized as activated by FOXA1, HNF4A, both, or neither.
