“… 27 , 28 Several studies have shown that HAGLR is associated with the proliferation, invasion, and metastasis of tumor cells. 29–34 Besides, the prognostic value of HAGLR in tumors has been evaluated. For example, Dong et al revealed that high expression of HAGLR is positively correlated with poorer prognosis of epithelial ovarian cancer patients.…”

Purpose Autophagy plays a crucial role in the initiation and progression of gastric cancer (GC). However, the role of autophagy-related lncRNAs in GC remains unknown. This study aimed to investigate the prognostic value of the autophagy-related lncRNA signature and its role in the tumor immune microenvironment (TIME) of GC. Methods RNA-sequencing (RNA-seq) and clinical data of GC patients were extracted from The Cancer Genome Atlas (TCGA) database. Univariate and multivariate Cox regression analyses were performed to identify the autophagy-related lncRNA prognostic signature which was validated in the test set and entire set. The survival and predictive performance were analyzed based on the Kaplan–Meier and ROC curves. Furthermore, the CIBERSORT algorithm was applied to explore the relationship between this signature and the immune cell infiltration. To elucidate the potential functions of autophagy-related lncRNAs in GC, we constructed the lncRNA-mRNA co-expression network and performed enrichment analysis. Principal component analysis (PCA) and Gene Set Enrichment Analysis (GSEA) were further performed to compare the different statuses between the high-risk and low-risk groups. Results We identified 5 autophagy-related lncRNAs (AL355574.1, AC010768.2, AP000695.2, AC087286.2, and HAGLR) to construct a prognostic signature. This signature could be an independent prognostic indicator for GC patients and had a higher prediction efficiency than other clinicopathological parameters. Furthermore, patients in the high-risk score group had a stronger immunosuppressive microenvironment than the low-risk group. The enrichment analysis for mRNAs co-expressed with these lncRNAs indicated that autophagy-related signaling pathways were remarkably enriched. PCA and GSEA further revealed different autophagy and immune statuses in the high- and low-risk groups. Conclusion The 5 autophagy-related lncRNA signature has significant clinical implications in prognosis prediction of GC. Meanwhile, our study elucidates the critical role of the autophagy-related lncRNA signature in the TIME of GC.

“…Although the functions of miR-877-3p have not been widely addressed, several studies of miR-877-3p have been reported. Zhu et al reported that enforced expression of miR-877-3p increased the expression of P16, which inhibits the proliferation of bladder cancer and Chen et al reported that overexpression of miR-877-3p abolished the migration and invasion of cervical cancer cell lines induced by HOXD-AS1 [ 35 , 36 ]. Another study showed the promotion of osteoblast differentiation of MC3T3-E1 cells by overexpression of miR-877-3p.…”

We aimed to investigate the effect of methotrexate (MTX) on microRNA modulation in rheumatoid arthritis fibroblast-like synovial cells (RA-FLS). RA-FLS were treated with MTX for 48 h. We then performed miRNA array analysis to investigate differentially expressed miRNAs. Transfection with miR-877-3p precursor and inhibitor were used to investigate the functional role of miR-877-3p in RA-FLS. Gene ontology analysis was used to investigate the cellular processes involving miR-877-3p. The production of cytokines/chemokines was screened by multiplex cytokine/chemokine bead assay and confirmed by ELISA and quantitative real-time PCR. The migratory and proliferative activities of RA-FLS were analyzed by wound healing assay and MKI-67 expression. MTX treatment altered the expression of 13 miRNAs (seven were upregulated and six were downregulated). Among them, quantitative real-time PCR confirmed that miR-877-3p was upregulated in response to MTX (1.79 ± 0.46-fold, p < 0.05). The possible target genes of miR-877-3p in RA-FLS revealed by the microarray analysis were correlated with biological processes. The overexpression of miR-877-3p decreased the production of GM-CSF and CCL3, and the overexpression of miR-877-3p inhibited migratory and proliferative activity. MTX altered the miR-877-3p expression on RA-FLS, and this alteration of miR-877-3p attenuated the abundant production of cytokines/chemokines and proliferative property of RA-FLS.

“…It is well established that most lncRNAs transmitted by exosomes located at the cytoplasm of the recipient, function as ceRNA to bind with miRNAs, which subsequently facilitate target gene expression [10]. HOXD-AS1 has been well characterized as a ceRNA to modulate progression in a variety of cancers, including glioma [33], hepatocellular carcinoma [34] and cervical cancer [35]. However, it's role as exosomal lncRNA in PCa cells remains unclear.…”

Background: Development of distant metastasis is the main cause of deaths in prostate cancer (PCa) patients. Understanding the mechanism of PCa metastasis is of utmost importance to improve its prognosis. The role of exosomal long noncoding RNA (lncRNA) has been reported yet fully understood in the metastasis of PCa. Methods: Co-culture assay, in-situ hybridization and quantitative PCR (qPCR) were applied to identify the presence of HOXD-AS1 overexpressing exosomes secreted by of castration resistant prostate cancer (CRPC) cells. Migration and wound healing assays were carried out to evaluate the biological function of exosomal HOXD-AS1. Then a mouse model was used to elucidate the effect of exosomal HOXD-AS1 on distant metastasis of PCa in vivo. Further RNA immunoprecipitation and luciferase assay were applied to identify the interaction between HOXD-AS1 and miR-361-5p. Moreover, rescue experiment was conducted to prove the binding of exosomal HOXD-AS1 and miR-361-5p. Last but not least, the application of serum exosomal HOXD-AS1 as a diagnostic and prognostic biomarker for PCa was evaluated. Results: We discovered the exosomal lncRNA HOXD-AS1 is upregulated in CRPC cell line derived exosomes and serum exosomes from metastatic PCa patients, which correlated with its tissue expression. Further investigation confirmed exosomal HOXD-AS1 promotes prostate cancer cell metastasis in vitro and in vivo by inducing metastasis associated phenotype. Mechanistically exosomal HOXD-AS1 was internalized directly by PCa cells, acting as competing endogenous RNA (ceRNA) to modulate the miR-361-5p/FOXM1 axis, therefore promoting PCa metastasis. In addition, we found that serum exosomal HOXD-AS1 was upregulated in metastatic PCa patients, especially those with high volume disease. And it is correlated closely with Gleason Score, distant and nodal metastasis, Prostatic specific antigen (PSA) recurrence free survival and progression free survival (PFS). Conclusions: Our study sheds a new insight into the regulation of PCa distant metastasis by exosomal HOXD-AS1 mediated miR-361-5p/FOXM1 axis, and provided a promising liquid biopsy biomarker as well as therapeutic target to the detection and treatment of metastatic PCa.
