It has also been proved that circ_0001023 could target miR-409-3p. Silencing circ_0001023 can impede the proliferation of GC cells and promote apoptosis, while miR-409-3p inhibitors can partially reverse the biological behavior of GC cells mentioned above. Moreover, the expression of circ_0001023 was reversely associated with miR-409-3p expression but positively correlated with PHF10, a downstream oncogene of miR-409-3p. Conclusion Collectively, it is concluded that circ_0001023 promotes the progression of GC via regulating miR-409-3p/PHF10 axis.Introduction Increasing evidence has shown that abnormally expressed long non-coding RNA (lncRNA) plays crucial roles in prostate cancer (PCa) progression. Materials and methods Here, we analyzed the expression level of lncRNA HAND2 antisense RNA 1 (HAND2-AS1) in PCa cells and tissues. Function assays were performed to investigate the biological roles of HAND2-AS1 in PCa cell behaviors. Bioinformatics methods, luciferase activity reporter assay, and RNA pull-down assay were performed to validate the connection of microRNA-106a-5p (miR-106a-5p) with HAND2-AS1. Also, the target of miR-106a-5p was explored using the same methods. Results Our results revealed HAND2-AS1 expression was decreased in both PCa cells and tissues. In vitro functional assays showed HAND2-AS1 could inhibit PCa cell proliferation and colony formation through promoting cell apoptosis. Dual-luciferase activity assays showed miR-106a-5p could directly bind with HAND2-AS1 and RNA binding motif protein 24 (RBM24). Mechanistically, we showed that HAND2-AS1 regulates PCa cell behaviors via targeting miR-106a-5p/RBM24 axis. Conclusion In summary, our results illustrated that HAND2-AS1 functions as miR-106a-5p sponge to regulate RBM24 expression, and to influence PCa progression.Background Circular RNA (circRNA) plays a critical role in tumorigenesis and tumor progression. Many studies indicate that circRNA Gprc5a is significantly upregulated and functions as an oncogene in a variety of cancers. However, the molecular mechanism of circGprc5a in liver cancer remains unclear. Methods qRT-PCR was used to measure the expression levels of circGprc5a, miR-1283, YAP1 and TEAD1 mRNA in hepatocellular carcinoma (HCC) tissues or cells. YAP1 and TEAD1 protein levels were detected by Western blot. CCK-8 assay, cell colony formation, BrdU incorporation and Annexin V-FITC/PI assays were performed to analyze the effects of circGprc5a and miR-1283 on cell proliferation and apoptosis. The relationship between circGprc5a, miR-1283, YAP1 and TEAD1 was analyzed using bioinformatic analysis and luciferase. The tumor changes in mice were detected by in vivo experiments. Results CircGprc5a was highly expressed in liver cancer, and closely related poor survival of patients with liver cancer. Knockout of circGprc5a inhibited proliferation of HCC and induced apoptosis. CircGprc5a activated the YAP1/TEAD1 signaling pathway by acting as a sponge for miR-1283. Furthermore, overexpression of miR-1283 abolished the promotion of circGprc5a on HCC cells. Therefore, miR-1283 expression correlated negatively with circGprc5a expression yet positively with the expression of YAP1/TEAD1 in liver cancer. Conclusion CircGprc5a promoted the development of HCC by inhibiting the expression of miR-1283 and activating the YAP1/TEAD1 signaling pathway.[This corrects the article DOI 10.2147/OTT.S231153.].Background Cervical cancer (CC) is a highly prevalent cancer and one of the main causes of death among women worldwide. The miR-181 family has turned out to be associated with tumorigenesis in a variety of tumors by regulating the expression of tumor-related genes. However, the mechanisms and biological function of miR-181c-5p in cervical squamous cell carcinoma (SCC) have not been well elucidated. Materials and methods SiHa cell lines with specific gene overexpression vectors were constructed. Targetscan was used to predict the binding site of miR-181c-5p and GSKIP. MTT assay was used to detect the clone formation rate. Flow cytometry was used to detect the apoptosis rate and to separate the cell markers. The Transwell test was used to detect cell invasion. Immunohistochemistry was used to detect protein expression in tumor tissues. Western Blotting was used to detect the expression levels of related proteins. Results GSKIP was predicted to be the target gene of miR-181c-5p in cervical SCC. MiR-181c-5p overexpression suppressed SiHa cells proliferation and promoted apoptosis; the protein expressions of Ki67 and PCNA were decreased, but the expressions of Caspase-3 and Bax/Bcl-2 were increased. The overexpression of miR-181c-5p inhibited the stem-like properties of SiHa cells; the expressions of SOX2, OCT4 and CD44 were decreased. Furthermore, miR-181c-5p upregulation limited the invasion of SiHa cells; the expression of E-cadherin was higher, but the expressions of N-cadherin and Vimentin were lower. MiR-181c-5p overexpression inhibited tumorigenesis in cervical SCC tissues; the expressions of Ki67, Caspase-3, CD44 and Vimentin in vivo were consistent with those in vitro. Conclusion Taken together, miR-181c-5p was able to mitigate the cancer cell characteristic and invasive properties of cervical SCC through targeting GSKIP gene.Objective miR-381 is implicated in the occurrence and development of various cancers, yet its role in head and neck squamous cell carcinoma (HNSCC) remains largely unknown. This study sought to research the direct target of miR-381 in HNSCC and investigate their roles in cancer progression. Methods miRNA and mRNA expression files of HNSCC were accessed from TCGA database and then processed for differential analysis. Bioinformatics databases were employed to predict the target mRNAs of the potential miRNA. qRT-PCR was conducted to determine the expression levels of the target miRNA and mRNA. Then, a series of in vitro experiments like CCK-8, colony formation assay, wound healing assay and transwell assay were performed to detect cell proliferation, migration and invasion. Dual-luciferase reporter gene assay was carried out for the further validation of the targeted relationship between the miRNA and mRNA. Results miR-381 was observed to be greatly down-regulated in HNSCC cells, and its overexpression could inhibit cell proliferation, migration and invasion. Besides, dual-luciferase reporter gene assay confirmed that STC2 was a direct target of miR-381, and their expression levels were reversely correlated. Moreover, rescue experiments demonstrated that overexpressing STC2 could rescue the inhibitory effect of miR-381 overexpression on cell proliferation, migration and invasion. Also, we verified that miR-381/STC2 exerted its function on HNSCC proliferation by mediating the FAK/PI3K/Akt/mTOR signaling pathway. Conclusion miR-381 suppresses cell proliferation, migration and invasion in HNSCC through targeting STC2, and participates in HNSCC development probably via the FAK/PI3K/Akt/mTOR signaling pathway.Vasculogenic mimicry (VM) is the formation of a "vessel-like" structure without endothelial cells. VM exists in vascular-dependent solid tumors and is a special blood supply source involved in the highly invasive tumor progression. VM is observed in a variety of human malignant tumors and is closely related to tumor proliferation, invasion, and recurrence. Here, we review the mechanism, related signaling pathways, and molecular regulation of VM in glioma and discuss current research problems and the potential future applications of VM in glioma treatment. This review may provide a new viewpoint for glioma therapy.As a result of the limited therapeutic options, advanced cervical cancer is difficult to treat, making the prognosis poor. Therefore, new therapeutic modalities or combinations need to be explored. We herein reported a case of stage IVB cervical cancer which was irresponsive to chemotherapy alone. Based on previous studies and after patient's consent was obtained, we made a therapeutic plan chemotherapy (albumin-bound paclitaxel and carboplatin) combined with immunotherapy (PD-1 inhibitor pembrolizumab). After 6 cycles of combined treatment, the patient got almost complete resolution with slight advent event. The treatment was further supported by local radiotherapy combined with immunotherapy. During the treatment period, disease was relatively stable, but the patient suffered severe grade 4 myelosuppression. We were therefore left with no other choice than to interrupt both chemotheraphy and radiotherapy. Before long, the tumor grew explosively again. These guided us to conclude that the combination use of albumin-bound paclitaxel (nab-paclitaxel) and carboplatin and pembrolizumab is effective and well tolerated in the treatment of advanced cervical cancer. The combined use of radiotherapy and pembrolizumab may also be effective. However, the combination use of chemotherapy, radiotherapy and immunotherapy in advanced cancer has not been well studied, and there are still many unsolved queries.Background Apatinib showed promising efficacy in the treatment of advanced or metastatic gastric cancer (mGC) in previous clinical studies. However, the real-world data are limited, and this study aimed to assess the effectiveness and safety of apatinib for the treatment of advanced or mGC in this setting. Methods In this prospective observational study, progression-free survival (PFS), overall survival (OS), overall response rate (ORR), disease control rate (DCR) and treatment-related adverse events (AEs) were recorded and evaluated. Univariate and multivariate analyses were conducted to explore potential biomarkers which might be related to the effectiveness. Results A total of 321 mGC patients from 47 centers in China were enrolled between July 1, 2015, and March 1, 2018. Thirty-two patients achieved partial response, 155 patients achieved stable disease, and 115 patients had progressive disease, and no CR was achieved, illustrating an ORR of 10.60% and a DCR of 61.92%. The median PFS and OS were 4.0 and 8.2 months, respectively. Multivariate Cox analysis showed that the potential biomarkers associated with longer PFS were combination regimens plus taxel/docetaxel, and apatinib initial dosage ≥500mg, occurrence of AEs of leukopenia, and hand-foot syndrome. Main AEs were proteinuria (17.1%), hypertension (15.9%), and handfoot syndrome (8.7%). Conclusion The present prospective observational study showed favorable effectiveness and safety of apatinib in real-world patients with advanced or metastatic GC in China. (A prospective, multi-center, non-intervention study of apatinib in the treatment of advanced gastric cancer-Trial Registry Number ChiCTR-OPN-15006601).Background Metformin is the first-line blood sugar control drug for type 2 diabetes, but recent epidemiological studies have shown that it inhibits the growth of a variety of tumours. However, few studies have examined metformin effects on gastric cancer (GC), and the anticancer mechanism has not been fully elucidated. Materials and methods We examined the inhibitory effect of metformin on GC cells by cell proliferation, migration and invasion assay. Transmission electron microscopy, confocal microscopy and Western blotting confirmed that metformin enhanced beclin1-dependent autophagy in gastric cancer cells. Decitabine TCGA database and tissue chip analysis confirmed the differential expression of beclin1 in GC and adjacent tissues. Relevant functional tests verified the role of beclin1 as a tumour suppressor gene in GC. Western blotting, cell proliferation, cell migration and invasion were used to verify that metformin enhances autophagy in GC cells through the AMPK-mTOR signalling pathway. Xenograft tumour models were constructed to explore the inhibitory effect of metformin and the role of beclin1 as a suppressor on GC in vivo.
