Background: Long non-coding RNA (lncRNA) breast cancer anti-estrogen resistance 4 (BCAR4) is a characterized oncogenic lncRNA in different cancers. This review is dedicated to summarize various molecular mechanisms of BCAR4 and demonstrate that the biological functions exerted by BCAR4 are good entry points for therapy. Methods: The molecular mechanism of BCAR4 acting on tumors is summarized by reviewing PubMed. Results: The expression of lncRNA BCAR4 is abnormally increased in all kinds of tumors, including colorectal cancer, prostate cancer, bladder cancer, gastric cancer, chondrosarcoma, glioma, breast cancer, glioma, gastric cancer, liver cancer, cervical cancer, lung cancer, etc. Besides, BCAR4 mediates multiple processes involved in carcinogenesis, including proliferation, invasion, anti-apoptosis, migration. Conclusion: BCAR4 may show great clinical value in this direction as a therapeutic cancer target.

Background: Long noncoding RNAs (lncRNAs) have been consistently demonstrated to be involved in gastric cancer (GC) as either tumor oncogenes or tumor suppressors. However, the detailed role of MIAT in GC remains poorly understood. Methods: The expression of MIAT in GC tissues was measured by In situ hybridization (ISH) assay. Cell proliferation, apoptosis, cycle, migration and invasion assays were performed to analyze the biological functions of MIAT in GC cells. Besides, western blotting was used to evaluate the role of MIAT in the expressions of P16, COX-2 and MMP-9. Results: In the present study, we identified that MIAT was up-regulated in GC tissues. Furthermore, silencing MIAT significantly suppressed GC cells proliferation, migration and invasion, promoted GC cells apoptosis, and induced GC cells cycle arrest in G1 phase. Additionally, knockdown of MIAT notably up-regulated the protein level of P16 and down-regulated the protein levels of COX-2 and MMP-9. Conclusion: These observations imply that silencing MIAT inhibits the proliferation, migration and invasion, promotes apoptosis, and induces cell arrest in G1 phase, partially through up-regulating the expression level of P16 and down-regulating the expression levels of COX-2 and MMP-9, indicating that MIAT may a novel biomarker and therapeutic target for GC.

ZEB1-AS1 is an Long non-coding RNA (lncRNA) that is abnormally expressed in various tumor types and affects tumor etiology and progression. ZEB1-AS1 can affect the malignant progression of gastric cancer through the miRNA-200b/Wnt1 axis. However, its effect on proliferation, invasion, and apoptosis of gastric cancer is unclear. Using BGC-803 cells, we studied the effects of lncRNA ZEB1-AS1 and miRNA-200b on the proliferation, invasion, and apoptosis of gastric cancer. Using qRT-PCR, we found that the expression of ZEB1-AS1 was significantly increased and the expression of miRNA-200b was significantly decreased in BGC-803 cells. By CCK-8, Transwell, and flow cytometry assays, we also found that down-regulation of ZEB1-AS1 and upregulation of miRNA-200b inhibited the proliferation and invasion of BGC-803 cells and promoted apoptosis. Furthermore, upregulation of ZEB1-AS1 and miRNA-200b reversed these effects. LncRNA ZEB1-AS1 inhibits the proliferation and invasion of gastric cancer cells and induces apoptosis by regulating the miRNA-200b/Wnt1 molecular axis.

Abstract Background Long non-coding RNAs (lncRNAs) have been reported to play a key role in gastric cancer (GC) tumorigenesis. However, the clinical application value of serum lncRNAs in GC has remained largely unknown. We investigated the role of a novel lncRNA named CTC-497E21.4 in the diagnosis and the prognosis of GC. Methods We focused on evaluation of lncRNA CTC-497E21.4 by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR). The study involved following aspects: (1) confirmation of the higher lncRNA CTC-497E21.4 expression in different types of GC specimens than corresponding controls; (2) evaluation of monitoring tumor dynamics by the serum lncRNA CTC-497E21.4 assay; (3) evaluation of the prognostic value of lncRNA CTC-497E21.4 assay in GC. Results (1) The method of RTFQ-PCR detection of lncRNA CTC-497E21.4 was evaluated to have high sensitivity and specificity. (2) The expression levels of lncRNA CTC-497E21.4 were higher in GC patients compared with corresponding controls (p<0.001), and the combination of serum lncRNA CTC-497E21.4, CEA and CA19-9 could improve diagnostic sensitivity (96.36%). (3) The serum lncRNA CTC-497E21.4 expression levels were lower in postoperative samples than preoperative samples (p=0.0021) and survival curves downloaded from TCGA showed high lncRNA CTC-497E21.4 levels were associated with poor OS of GC (p=0.0351). Conclusions lncRNA CTC-497E21.4 may be a potential biomarker for the diagnosis and the prognosis of GC.
