Results from Li et al. indicated that LncRNA potassium voltage-gated channel subfamily Q member 1 opposite strand 1 (KCNQ1OT1) could directly bind to Homeobox A9 (HOXA9) to further regulate the proliferation, invasion and metastasis of Laryngeal squamous cell carcinoma cells. This evidence concerns the gene HOXA9 and laryngeal squamous cell carcinoma.
