Homeobox (HOX) transcript antisense intergenic RNA (HOTAIR), a long non-coding RNA (lncRNA), is associated with a variety of human cancers, such as breast, liver and lung cancer.
Thus, targeting the PDK1- and HOTAIR-mediated downstream molecule EZH2 by the combination of ATL-1 and erlotinib potentially facilitates the development of an additional novel strategy to combat lung cancer.
In addition, linkage disequilibrium and haplotype analysis of HOTAIR gene polymorphisms for susceptibility to lung cancer revealed a high degree of linkage disequilibrium between the rs920778 and rs1899663 loci (D' = 0.86, r2 = 0.52).
We found that none of the two HOTAIR polymorphisms (rs12826786 T>C, rs1899663A>C) has any significant association with the increased risk of lung cancer in any type of inheritance genetic models.
Previous studies have shown that expression of the long non-coding RNA HOX transcript antisense RNA (HOTAIR) is upregulated in lung cancer, which is correlated with metastasis and poor prognosis.
HOTTIP, CCAT2, H19, HOTAIR, MALATI, ANRIL genetic polymorphisms were significantly associated with lung cancer susceptibility or platinum-based chemotherapy response.
From the four lncRNAs, three lncRNAs (SNHG1, H19, and HOTAIR) are identified as a biomarker panel, producing 82.09% sensitivity and 89.23% specificity for diagnosis of lung cancer.
Our data indicates that HOTAIR is overexpressed in metastatic lung cancer tissue, which is prospectively associated with the ability of HOTAIR to promote lung cancer cell motility and invasion.
Evidence suggests that both 14-3-3σ and long non-coding RNA HOX transcript antisense RNA (HOTAIR) are involved in the tumorigenesis and progression of lung cancer.
We also discuss HOTAIR's potential in diagnosis and treatment of lung cancer, as well as the challenges of exploiting HOTAIR for intervention of lung cancer.
