Human osteosarcoma usually presented a high tendency to metastatic spread and caused poor outcomes, however, the underlying mechanism was still largely unknown. In the present study, using a series of in vitro experiments and an animal model, we investigated the roles of HOX antisense intergenic RNA (HOTAIR) during the proliferation and invasion of osteosarcoma. According with our results, HOTAIR was commonly overexpressed in osteosarcoma, which significantly correlated with advanced tumor stage, highly histological grade and poor prognosis. In vitro and in vivo experiments demonstrated that knockdown of HOTAIR could notably suppress cellular proliferation, inhibit invasion and decrease the secretion of MMP2 and MMP9 in osteosarcoma. Collectively, our results suggested that HOTAIR might be a potent therapeutic target for osteosarcoma.

Molecular changes have a substantial impact on the onset of colorectal cancer (CRC). Complexes of HOTAIR and miRNAs disrupt several cellular functions during carcinogenesis, primarily by disrupting several carcinogenic signaling pathways. In the present study, the relationships between the serum levels of transforming growth factor-β1 (TGF-β1), sirtuin-1 (SIRT1) and E-cadherin and those of HOX transcript antisense intergenic RNA (HOTAIR) and microRNA-130a (miR-130a) in individuals with CRC were analyzed, including their correlations and diagnostic potential.

Background: Recent studies have highlighted the potential role of several long non-coding RNAs (lncRNAs) in the pathogenesis of Behçet's disease (BD). This study investigated the expression profiles of lncRNA NEAT1 and lncRNA HOTAIR, and their target cytokine genes, IL-6 and TNF-α, in active and inactive BD patients.
Methods: This cross-sectional study was conducted on peripheral blood mononuclear cells (PBMCs) obtained from 25 BD patients and 25 age-sex-matched healthy controls (HCs).

Objective To investigate the effect of serum containing Xinfeng capsule (XFC) on the angiogenesis of human umbilical vein endothelial cells (HUVEC) induced by rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) and its mechanism of action. Methods An in vitro co-culture model of RA-FLS and HUVEC was established. Serum containing XFC was prepared by oral gavage of SD rats.

Background: Numerous studies have demonstrated the significance of long noncoding RNA (lncRNA) in the development of cancer metastasis. The expression levels of many lncRNAs are elevated in metastatic lung cancer patients compared to non-metastatic lung cancer patients.
Objectives: The primary objective of the study was to investigate the association between the expression levels of three lncRNAs (MALAT1, HOTAIR, and AFAP1-AS1) and lymph node metastasis (LNM) of lung cancer.

Background: Breast cancer (BC) is a multifactorial disease of unknown etiology whose major risk factors are genetic alterations of cell proliferation and migration pathways. HOX transcript antisense RNA gene (HOTAIR) is a long noncoding RNA (lncRNA) related to cell proliferation, progression, invasion, metastasis, and poor survival of multiple cancers, including BC. Controversial results have emerged on the association between breast cancer risk in multiple ethnicities.
