AbstractRAS and its downstream cascades transmit cellular signals, resulting in increased transcription of genes involved in cell growth and division. Protein-coding gene targets of RAS signaling have been characterized extensively, but long noncoding RNAs (lncRNA) regulated by these processes have not. Using a customdesigned lncRNA microarray, we identified the lncRNA Orilnc1 as a genetic target of RAS that is critical for RAS oncogenicity. Orilnc1 expression was regulated by RAS–RAF–MEK–ERK signaling via the transcription factor AP1. Orilnc1 was highly expressed in BRAF-mutant cancers, such as melanoma. Silencing of Orilnc1 blocked tumor cell proliferation and growth in vitro and in vivo. In addition, Orilnc1 blockade reduced expression of cyclin E1 and induced G1–S cell-cycle arrest in tumor cells. Taken together, our results identify Orilnc1 as a novel, nonprotein mediator of RAS/ RAF activation that may serve as a therapeutic target in RAS/RAF– driven cancers.
