Abstract Long non-coding RNAs (lncRNAs) have been implicated in cancer progression and drug resistance development. Moreover, there is evidence that lncRNA HOX transcript antisense intergenic RNA (HOTAIR) is involved in colorectal cancer (CRC) progression. The present study aimed to examine the functional role of lncRNA HOTAIR in conferring radiotherapy resistance in CRC cells, as well as the underlying mechanism. The relative expression levels of HOTAIR were examined in 70 pairs of CRC tumor and para-cancerous tissues, as well as in radiosensitive and radioresistant samples. The correlations between HOTAIR expression levels and clinical features of patients with… More >

Abstract miR-101-3p has been identified as a tumor suppressor in several cancers, but its exact role in gastric adenocarcinoma is still largely unknown. In this study, we found that, compared with the RGM-1 human normal gastric epithelial cells, miR-101-3p was significantly downregulated in all six human gastric adenocarcinoma cell lines, including BGC-823, MNK-45, MGC-803, SGC-7901, AGS, and HGC-27. Overexpression of miR- 101-3p suppressed both the proliferation and invasion of AGS gastric adenocarcinoma cells, and knockdown of miR-101-3p displayed the opposite effect. In addition, miR-101-3p could directly target and suppress the expression of the serum response factor More >

Abstract Non-small cell lung cancer (NSCLC) is one of the most deadly cancers with poor prognosis. Recent findings suggested that the lncRNA HOTAIR played an important role in tumorigenesis and metastasis. In the present study, HOTAIR was highly expressed in NSCLC tumor tissues and cell lines (H1299, H23, H292, and A549). Downregulation of HOTAIR suppressed cell proliferation and invasion, while it promoted apoptosis of NSCLC cells. The targeting relationship between HOTAIR and miR-613 was first revealed by bioinformatics prediction. miR-613 was found to be lowly expressed in NSCLC tumor tissues and cell lines. Knockdown of HOTAIR… More >

Abstract The long noncoding RNA HOX transcript antisense RNA (HOTAIR) has been found to be overexpressed in many human malignancies and involved in tumor progression and metastasis. Although the downstream target through which HOTAIR modulates tumor metastasis is not well known, evidence suggests that microRNA-197 (miR-197) might be involved in this event. In the present study, the significance of HOTAIR and miR-197 in the progression of colorectal cancer was detected in vitro and in vivo. We found that HOTAIR expression was significantly increased in colorectal cancer cells and tissues. In contrast, the expression of miR-197 was More >

Abstract Increasing evidence has indicated that long noncoding RNAs (lncRNAs) are a class of significant regulators in various tumorigenesis processes. The lncRNA homeobox transcript antisense RNA (HOTAIR) has been reported to act as a functional lncRNA in cervical cancer development. The present study investigated the underlying mechanism of HOTAIR and miR-17-5p in cervical cancer tumorigenesis. The results showed that HOTAIR expression was significantly upregulated in both cervical cancer tissues and cell lines. Lossof-function experiments showed that HOTAIR knockdown inhibited the proliferation, migration, and invasion of cervical cells. In addition, miR-17-5p expression was downregulated in cervical cancer More >

Abstract Propofol, a common intravenous anesthetic used in clinical, has been shown to regulate cells proliferation, inflammation, angiogenesis and metastasis as well as exerting anti-cancer effect in several different types of cancer. However, the functions and mechanisms of propofol in lactate secretion and invasion of cancer cells remain unknown. The primary aim of this study was to investigate the role of propofol in cells migration and invasion of colon cancer (CRC). Scratches assay, Transwell assay were used to detect colon cells migration and invasion. Real-time Quantitative Polymerase Chain Reaction (RT-qPCR), Western blotting were utilized to detect… More >
