LINC00662 and laryngotracheoesophageal cleft: Xu et al. (2020) reported elevated LINC00662 expression in LC cells, which accelerated both their proliferation and colony formation. In addition, LINC00662 expression has been shown to promote invasion, metastases, and the stemness of LC stem cells as well (Gong et al., 2018). Moreover, Lv et al. (2021) reported that LINC00662 promoted the growth progression of non-small cell LC in vivo on the basis of enhanced proliferation in LC cells.
