NSD2 and cancer: To elucidate the physiological role of NSD2, we analyzed the correlation of expression levels between NSD2 and NSD2‐target genes in 37 human normal tissues and 1,019 human cancer cell lines using the Human Protein Atlas (HPA) and Cancer Cell Line Encyclopedia (CCLE), respectively (Barretina et al., 2012; Uhlén et al., 2015).
