HOXA11 and metastatic malignant neoplasm: Three lncRNAs among the 12, HOXA11-AS, RNF144A-AS1, and RP11-1246C19.1, were continuously up-regulated among normal-primary-metastatic progress; lncRNA RP11-693J15.4 was up-regulated between normal-primary while reversely down-regulated between primary-metastatic cancer, and the other eight lncRNAs were continuously down-regulated among normal-primary-metastatic progress (Figure 4).
