miR‐125b is a known tumour suppressor gene that blocks translation of a number of transcripts involved in the control of cell proliferation in various cancers 33, but a convincing association of miR‐125 and p16 expression has not been reported, with the exception of a study showing that hsa‐miR‐125b exhibited significant negative correlations with CDKN2A expression in glioblastoma multiforme 38. This evidence concerns the gene CDKN2A and glioblastoma.
