Antisense non‐coding RNA in the INK4 locus (ANRIL), a 2659 bp nuclear and perinuclear cytoplasmic antisense lncRNA, is identified to co‐cluster with ARF (also known as p14ARF or cyclin‐dependent kinase inhibitor 2A) in a melanoma‐neural system tumour family.66 In another study, ANRIL was shown to be upregulated whereas INK4A and INK4B were downregulated in cutaneous melanoma tissues and melanoma cell lines. Here, CDKN2B-AS1 is linked to melanoma.
