Enriched TFBSs in core HIF binding regions (Fisher’s exact test).

Enriched sequence motifs in core HIF binding regions, as indicated by statistical analysis (Fisher’s exact test, p<0.05 with no correction for multiple comparisons). For each overrepresented sequence motif/PWM, the table indicates the following: the database collection (PWM collection), the stringency used in in silico TFBS identification (Stringency), the number of hits obtained in the set of core HBRs (Hits), the transcription factor (Tr. Factor) associated to the PWM and the p value of the enrichment (p value). Robust predictions across different stringencies and PWM datasets are highlighted in bold.
