The aim of the present study was to investigate the radiosensitizing effects of homeobox (HOX) transcript antisense RNA (HOTAIR) long non-coding RNA on breast cancer tumor cells and examine the underlying mechanisms. Recombinant plasmid vectors containing HOTAIR gene were constructed and MDA-MB231 cells were transfected with these plasmids using liposomes. The cells were treated with radiation ...

Understanding the mechanisms of androgen receptor (AR) activation in the milieu of low androgen is critical to effective treatment of castration-resistant prostate cancer (CRPC). Here, we report HOTAIR as an androgen-repressed lncRNA, and, as such, it is markedly upregulated following androgen deprivation therapies and in CRPC. We further demonstrate a distinct mode of lncRNA-mediated gene regu...

BACKGROUND As a member of non-coding RNAs family, long non-coding RNAs' functions in cancer needs to be further investigated. It has been indicated that the functions of Hox transcript antisense intergenic RNA (lncRNA: HOTAIR) include reprogramming chromatin organization and promoting tumor metastasis such as breast and colorectal tumor. The aim of this study is to investigate the functions of ...

The role of long noncoding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR) and its functional single nucleotide polymorphisms (SNPs) in papillary thyroid carcinoma (PTC) is still largely unclear. Therefore, we investigated the involvement of lncRNA HOTAIR and its three haplotype-tagging SNPs (htSNPs) in PTC. There was higher expression of HOTAIR in PTC tissues compared to normal tissues. A s...

Expression of HOX transcript antisense intergenic RNA (HOTAIR), a large intergenic noncoding RNA (lincRNA), has been described as a metastases-associated lincRNA in various cancers including breast, liver and colon cancer cancers. We sought to determine if expression of HOTAIR could be used as a surrogate for assessing nodal metastases and evaluated RNA in situ hybridization (RNA-ISH) assay in ...

BACKGROUND AND AIM The biological functions of non-coding RNAs (ncRNAs) have been widely identified in many human diseases. In the present study, the relationship between long non-coding RNA HOTAIR and microRNA-17-5p (miR-17-5p) and their roles in osteogenic differentiation and proliferation in non-traumatic osteonecrosis of femoral head (ONFH) were investigated. METHODS The expression levels...

Artesunate (ART) has anti-cancer activities for a variety of solid tumors. The aim of this study was to investigate the anti-metastatic effect of ART on cervical cancer cells. In vivo anti-metastatic effect of ART was investigated in mice with the lung metastasis model by the subcutaneous injection of ART. The interaction of HOTAIR and COX-2 was measured by RNA immunoprecipitation and RNA pull-...

OBJECTIVES Although the Hox transcript antisense intergenic RNA (HOTAIR), a vital long non-coding RNA, is known to participate in the development and progression of a wide range of carcinomas, there are still no published reports regarding its expression in adenocarcinoma of esophagogastric junction (AEJ). The aims of this study were to investigate the expression of HOTAIR, and to analyze the a...

Increasing evidence suggests that long non coding (lnc)RNA and microRNA (miRNA/miR) both regulate the expression of key genes in tumorigenesis and have considerable theranostic potential. Rapid advances in bioinformatics indicate that miRNA may potentially interact with lncRNA to modulate their regulatory roles. miR-148b-3p has been reported to have a vital role in regulating tumor progression....
