Results of both our cohort and Lnc2Cancer 3.0 cohort showed that HOXA11-AS expression increased with the tumor progression during I to III stage of gastric cancer but decreased in IV stage patients (see Additional file 3: Figure S2 a and g), and the same is observed in tumor T stage of our cohort (see Additional file 3: Figure S2 b). Here, HOXA11 is linked to neoplasm.
