HOTAIR is an lncRNA that has been known to have an oncogenic role in different cancers. There is limited knowledge of genetic and epigenetic elements and their interactions for the gene encoding HOTAIR. Therefore, understanding the molecular mechanism and its regulation remains to be challenging. We used different in silico analyses to find genetic and epigenetic elements of HOTAIR gene to gain...
Long non-coding RNAs have been reported to play an important role in cellular metabolism and development. Homeobox transcript antisense intergenic RNA (HOTAIR), a long non-coding RNA, is pervasively over-expressed in most human cancers compared with non-cancerous adjacent tissues. Although many articles have reported that HOTAIR is closely associated with metastasis, epithelial-mesenchymal tran...
Large intergenic noncoding RNAs (lincRNA) have been less studied than miRNAs in cancer, although both offer considerable theranostic potential. In this study, we identified frequent upregulation of miR-196a and lincRNA HOTAIR in high-risk gastrointestinal stromal tumors (GIST). Overexpression of miR-196a was associated with high-risk grade, metastasis and poor survival among GIST specimens. miR...
Background:Dysregulation of HOX Transcript Antisense Intergenic RNA (HOTAIR) has been linked to the etiopathogenesis of several human cancers. According to epidemiological evidences, the risk of susceptibility to breast cancer varies among different populations. This study was designed to determine the transcriptional level of HOTAIR in tumor cells of breast cancer pat...
PURPOSE Long non-coding RNAs (lncRNAs) play important roles in the malignant behavior of cancer. HOTAIR, a well-studied lncRNA, contributes to breast cancer development, and overexpression of HOTAIR predicts a poor prognosis. However, the regulatory role of HOTAIR in the cancer stem-like cell (CSC) subpopulation remains largely unknown. Our goal was to determine the regulatory functions of HOTA...
Long non-coding RNA HOTAIR exerts regulatory functions in various biological processes in cancer cells, such as proliferation, apoptosis, mobility, and invasion. We previously found that HOX transcript antisense RNA (HOTAIR) is a negative prognostic factor and exhibits oncogenic activity in hepatocellular carcinoma (HCC). In this study, we aimed to investigate the role and molecular mechanism o...
The functional impact of recently discovered long noncoding RNAs (ncRNAs) in human cancer remains to be clarified. One long ncRNA which has attracted attention is the Hox transcript antisense intergenic RNA termed HOTAIR, a long ncRNA expressed from the developmental HOXC locus located on chromosome 12q13.13. In cooperation with Polycomb complex PRC2, the HOTAIR long ncRNA is reported to reprog...
To explore whether the alteration of lncRNA expression is correlated with polycyclic aromatic hydrocarbons (PAHs) exposure and DNA damage, we examined PAHs external and internal exposure, DNA damage and lncRNAs (HOTAIR, MALAT1, TUG1 and GAS5) expression in peripheral blood lymphocytes (PBLCs) of 150 male coke oven workers and 60 non-PAHs exposure workers. We found the expression of HOTAIR, MALA...
Previous studies have demonstrated that the presence of Hox transcript antisense intergenic RNA (HOTAIR) is correlated with poor survival in several types of cancer, including breast cancer, and promotes tumor metastasis. Currently, little is known regarding the correlation between HOTAIR and chemoresistance in cancer. The current study aimed to investigate the role of HOTAIR in epithelial ovar...
HOTAIR, a long non-coding RNA (lncRNA), plays a crucial role in tumor initiation and metastasis by interacting with the PRC2 complex and the modulation of its target genes. The role of HOTAIR in gastrointestinal stromal tumors (GISTs) is remains unclear. Herein we investigate the mechanism of HOTAIR in the genesis and promotion of GISTs. The expression of HOTAIR was found to be higher in surgic...
