CDKN1B and cancer: As anticipated from our RNA-Seq analysis (Fig. 4c and Supplementary Data 2), this regulation of cyclin D1 by SMARCA4 in these cell line pairs was not observed for other relevant cell cycle genes including CCND3, CCNE1, CDKN1B, and CDKN1A (Supplementary Fig. 8), although CCNE1 and CDKN1A have been shown to be regulated by SMARCA4 in other cancer types, likely due to context dependency40,41.
