UNC5B and retinoblastoma: Interestingly, UNC5B was already highly expressed in many SCLC (NCI-H69, NCI-N417, NCI-H82) and some other YAPoff cell lines (retinoblastoma/RB1021, neuroendocrine prostate/NCI-H660) relative to YAPon lines (Fig. 3G), which may explain why YAP does not further increase expression in some contexts.
