To further elucidate the roles of RORB in NB progression, we chose SK‐N‐BE(2), IMR‐32, SH‐SY5Y, and SK‐N‐AS (representing relatively low or high RORB expression) cells as models for stable over‐expression or knockdown studies, resulting in decrease or increase of cellular viability, respectively (Figure 1E,F; Figure S1F,G, Supporting Information). The gene discussed is RORB; the disease is neuroblastoma.
