GATA5 and Patent ductus arteriosus: As the promoters of HNF1A upregulated genes were enriched for transcription factor known to play roles in PDA including GATA (likely GATA5 or GATA6) (Roe et al., 2017; Martinelli et al., 2017; Zhong et al., 2011), PDX1 (Roy et al., 2016), and SOX9 (Camaj et al., 2014; Kopp et al., 2012; Tsuda et al., 2018), it is possible that HNF1A may work in concert with other transcription factors to elicit its full oncogenic function in PDA.
