LINC00668 and laryngeal squamous cell carcinoma: Zhao et al. (18) showed that in laryngeal squamous cell carcinoma, the expression levels of LINC00668 were associated with age, pathological differentiation degree, T stage, clinical stage, and cervical lymph node metastasis, and using a series of bioinformatics tools and in vitro experiments, proved that knockdown of LINC00668 can inhibit the proliferation, migration, and invasion ability of laryngeal squamous cell carcinoma cells.
