ROBO1 and carcinoma: Intron2 of ROBO1 harbors two non-coding RNAs [ncRNAs; BC017743 and BC043430], suggesting their probable role in modulating the expression of ROBO1. The expression pattern of these ncRNAs in CACX has not yet been studied but their differential expression has been detected in various carcinomas like; lung, breast, oral etc [15], [16].
