bet‐1 is the ortholog of human BRD4, a bromodomain protein involved in cell fate decisions in both C. elegans (Shibata et al., 2010) and mammals (Lee et al., 2017; Linares‐Saldana et al., 2021), and also implicated in cancer progression (Huang et al., 2016). This evidence concerns the gene BRD4 and cancer.
