Overexpression of lncRNA HOTAIR promoted proliferation, migration, and invasion in renal carcinoma cells.118 Hu et al revealed that STAT3, as a signal transducer and activator, is a downstream gene in the miR‐124 regulatory network in retinoblastoma and that miR‐124 expression is controlled by the lncRNA XIST. This evidence concerns the gene XIST and retinoblastoma.
