XIST and retinoblastoma: The interaction between XIST and miR‐124/STAT3 contributed to the progression of retinoblastoma.119 Finally, epigenetic regulation of small nucleolar RNA host gene 16 (SNHG16) was also a target of miR‐124‐3p, and inhibiting miR‐124‐3p reversed SNHG16‐mediated tumor suppressive functions in acute lymphoblastic leukemia (ALL).120
