For example, it has been reported that the expression levels of HOXA10-AS, HOXA11-AS, and HOXA-AS are significantly upregulated in lung adenocarcinoma (LUAD), and their high expression levels in such a cancer type are associated with shorter survival periods in patients (Hao and Yu, 2018; Dasti et al., 2020). Here, HOXA11 is linked to lung adenocarcinoma.
