Abstract
Background: We aimed to evaluate the effects of lncRNA PTV1 on colon cancer proliferation and migration via the Wnt6/β-catenin2 pathway. Materials and Methods: A total of 117 colon cancer and normal adjacent tissue samples were collected. LncRNA PVT1 and miR-1207-5p expressions in these samples and colon cancer cell lines were detected by Quantitative reverse transcription-polymerase chain reaction (qRT-PCR). LncRNA PVT1-silencing cells and miR-1207-5p-overexpressing Caco-2-siPVT1 cells were constructed, respectively. The effects of lncRNA PVT1 silencing on cell proliferation were assessed by MTT and colony formation assays. The effects on invasion and migration were tested by Transwell and scratch assays respectively. The targeting regulatory relationship between miR-1207-5p and Wnt6 was analyzed by a dual-luciferase reporter assay. The relationship between lncRNA PVT1 and miR-1207-5p was studied by RNA-binding protein immunoprecipitation and RNA pull-down assays. The expressions of proteins in the Wnt6/β-catenin2 pathway were detected by Western blotting. Results: The lncRNA PVT1 mRNA expression in colon cancer tissue was significantly higher than that in normal adjacent tissue (p < 0.05). The expression in lncRNA PVT1-silencing cells was significantly down-regulated (p < 0.05). The colonies of Caco-2-siPVT1 cells decreased, accompanied by a reduced number of cells penetrating Matrigel and migration (p < 0.05). Compared with siPVT1 + NC group, the number of colonies and migration of siPVT1 + miR-1207-5p-overexpressing group increased significantly (p < 0.05). There was a targeting relationship between miR-1207-5p and PVT1. MiR-1207-5p had a targeted binding site with Wnt6. The protein expressions of Wnt6/β-catenin2 in Caco-2-siPVT1 group were significantly lower than those of control and Caco-2-siNC groups (p < 0.05). Conclusion: LncRNA PVT1 was highly expressed in colon cancer. It may enhance the proliferation and migration of colon cancer cells by up-regulating miR-1207-5p level and enhancing the Wnt6/β-catenin2 pathway.

Abstract
Nasopharyngeal carcinoma (NPC) is a typical type of malignant tumor. This research paper aims to study the function and mechanism of long non-coding RNA lung adenocarcinoma-related transcript 1 (lncRNA-LUADT1) in the progression of NPC. In this study, the expressions of lncRNA-LUADT1, miR-1207-5p, and TEAD1 in NPC tissues and cell lines were detected by RT-qPCR. Initially, the expression of lncRNA-LUADT1 and TEAD1 were significantly up-regulated in NPC tissues and cells, while miR-1207-5p was significantly down-regulated. Next, miR-1207-5p was confirmed to bind to lncRNA-LUADT1 or TEAD1 by bioinformatics and luciferase reporter assay. In addition, after interfering with lncRNA-LUADT1 expression, experiments of CCK8, EDU staining, and Transwell invasion were used to detect proliferation, invasion, and migration of NPC cells. The results showed that interfering with lncRNA-LUADT1 expression could inhibit the proliferation, invasion, and migration of NPC cells. Western blot showed that lncRNA-LUADT1 knockdown significantly decreased the expression of Hippo/YAP pathway protein (YAP1 and TAZ). However, interfering with the expression of miR-1207-5p reversed these results. In addition, the nude mouse tumor formation experiment suggested that low-expressed lncRNA-LUADT1 reduced the volume and weight of tumor tissues. In summary, lncRNA-LUADT1 down-regulation could inhibit NPC cell proliferation and invasion, which may be achieved through regulating miR-1207-5p expression and affecting TEAD1 expression, thus inhibiting the activation of Hippo/YAP signaling pathway.

Abstract
Prostate cancer, the most common non-cutaneous male cancer, is a public health problem with a third prevalence worldwide. PYCR1 and miR-1207-5p dysregulations were found in cancer progression. Our study aims to reveal the biological role of miR-1207-5p-PYCR1 axis in prostate cancer progression. First, we investigated the expression of miR-1207-5p in prostate cancer tissues and cell lines by RT-qPCR. Next, we confirmed miR-1207-5p targeting PYCR1 by luciferase assay. CCK-8 assay, BrdU assay, flow cytometry, and tanswell assay were applied for examining cell proliferation, apoptosis, and invasion in prostate cancer cells, respectively. In the present study, decreased miR-1207-5p expression was obviously observed in prostate cancer tissues and cells. Upregulation of miR-1207-5p hampered cellular proliferation and invasion, while enhanced cellular apoptosis. In addition, upregulation of PYCR1 elevated cell proliferation and invasion, but repressed apoptosis of prostate cancer cells. Moreover, miR-1207-5p inhibited the expression of PYCR1 to repress prostate cancer tumorigenesis. MiR-1207-5p inhibited the expression of PYCR1 to repress the progression of prostate cancer by inhibiting cell growth and elevating cell apoptosis. Overall, our study clarifies the biological role of miR-1207-5p-PYCR1 axis in prostate cancer progression, which might be effective biomarkers for clinical treatment of prostate cancer.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is the second most common head and neck cancer. Previously, we discovered that miR-1207-5p was downregulated in LSCC. In this study, the clinical significance, function, and mechanism of miR-1207-5p in LSCC were investigated. Downregulation of miR-1207-5p was found to be strongly linked to the malignant progression of LSCC. Functional studies revealed that miR-1207-5p upregulation suppressed LSCC cell proliferation, invasion, migration, and xenograft tumor growth. Bioinformatics analysis revealed that miR-1207-5p target genes were involved in cell cycle regulation, proliferation, adhesion, and the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. Mechanistic studies revealed that miR-1207-5p interacts directly with the 3′ untranslated region of spindle and kinetochore associated complex subunit 3 (SKA3) and downregulates SKA3 expression. Furthermore, SKA3 was found to be overexpressed in LSCC, and its high expression was associated with tumor progression and a poor prognosis. Rescue experiments demonstrated that miR-1207-5p inhibited the malignant phenotypes of LSCC via SKA3. Furthermore, miR-1207-5p upregulation or knockdown of SKA3 inhibited the epithelial-mesenchymal transition (EMT). Collectively, miR-1207-5p inhibited LSCC malignant progression by downregulating SKA3 and preventing EMT. These findings provide new insights into the mechanism of LSCC progression, as well as new potential biomarkers and therapeutic targets for LSCC diagnosis and treatment.

Abstract
Purpose LncRNAs play an important role in tumorigenesis and cancer progression in liver cancer. Although many lncRNAs have been reported, the role of MIR194-2HG and the underlying mechanism mediated by it are still largely unknown in HCC. This study aimed to investigate the biological role and mechanism of MIR194-2HG in liver cancer. Materials and Methods The expression of MIR194-2HG was determined in liver cancer tissues and cells by RT-qPCR. The overall survival rate of MIR194-2HG was analyzed by Kaplan–Meier survival analysis. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), colony formation, and Transwell assays were carried out to detect cell migration and invasion. Western blotting was used to quantify the levels of all proteins. The regulatory mechanism of the MIR194-2HG/miR-1207-5p/TCF19 axis in liver cancer was investigated by dual-luciferase activity reporter assay, Kaplan-Meier survival analysis, and Western blotting. Results MIR194-2HG was upregulated in liver cancer tissues and cell lines. Liver cancer patients with higher expression of MIR194-2HG revealed poor overall survival compared with those who had lower expression of MIR194-2HG. MIR194-2HG promoted the proliferation, migration, and invasion of HepG2 and Huh7 cells by acting as a ceRNA mechanism for the miR-1207-5p/TCF19 axis to activate the Wnt/β-catenin signaling pathway. Conclusion MIR194-2HG acts in an oncogenic role and activates the Wnt/β-catenin signaling pathway via a miR-1207-5p/TCF19 axis-mediated mechanism, which provides a novel avenue for diagnostic or therapeutic interventions in liver cancer.

Abstract
BACKGROUND Osteoarthritis (OA) is a prevalent chronic diseases characterized by formation of osteophytes and degradation of articular cartilage. Previous evidence has identified the regulatory effects of microRNAs (miRNAs) in OA. The goal of this study is to clearly explore the biological function of miR-1207-5p in OA. METHODS MiR-1207-5p and C-X3-C motif chemokine receptor 1 (CX3CR1) expression in OA cartilages were revealed by accessing to Gene Expression Omnibus database. In vitro OA model was established by lipopolysaccharide (LPS) stimulation. Western blot and quantitative real-time polymerase chain reaction were conducted to detect the expression level of genes. Cell counting kit-8 (CCK-8) and flow cytometric experiments were performed to investigate the proliferation and apoptosis capacities of CHON-001 cells. Bioinformatics analysis was applied to predict the binding site of miR-1207-5p and CX3CR1, the connections of which were ascertained using luciferase reporter assay. RESULTS MiR-1207-5p expression was decreased while CX3CR1 was increased in OA cartilages. Up-regulation of miR-1207-5p alleviated the LPS-induced damage in the view of cell proliferation, apoptosis and extracellular matrix (ECM) degradation. A target of miR-1207-5p CX3CR1, its down-regulation intensified the impacts of miR-1207-5p mimic, promoted proliferation and mitigated apoptosis. LPS exposure increased the protein expression of the phosphorylated IκBα and P65, and this phenomena was reversed due to miR-1207-5p up-regulation and CX3CR1 knockdown. The treatment of Betulinic acid (BA; an activator of nuclear factor-κB pathway) reversed the miR-1207-5p mimic-induced inhibitory effect on apoptosis in LPS-treated CHON-001. CONCLUSION Our results highlight that miR-1207-5p can prevent CHON-001 from LPS-stimulated injury, providing a novel biomarker for OA progression and further advancing treatment of OA.

Abstract
During the development of primary Sjögren's syndrome (pSS), aberrant expression of autoantigen is a hallmark event. To explore the regulation of autoantigen tripartite motif containing 21 (Ro/SSA, TRIM21), microRNA profiling was performed in our previous study. In which, two TRIM21-targeting microRNAs were identified, namely miR-1207-5p and miR-4695-3p. To further pursue their roles in the development of pSS, assays were performed with cultured human submandibular gland (HSG) cells, and salivary gland tissues. Results showed that transfection of miR-1207-5p or miR-4695-3p mimics down-regulated not only the expression of TRIM21, but also the levels of pro-apoptotic genes B cell lymphoma 2 associated X (BAX), Caspase 9 (CASP-9) and Caspase 8 (CASP-8). This finally led to antiapoptotic phenotypes in HSG cells. Consistent with the antiapoptotic activity, transfection of microRNA inhibitors up-regulated the expression of TRIM21 and led to a pro-apoptotic phenotype. These therefore propose miR-1207-5p and miR-4695-3p as two antiapoptotic microRNAs functioning through apoptosis pathway. Supporting this speculation, assays performed with salivary gland tissues revealed down-regulation of miR-1207-5p and miR-4695-3p, as well as up-regulation of TRIM21 and pro-apoptotic CASP-8 gene in pSS samples. SIGNIFICANCE OF THE STUDY: For pSS patients, apoptosis of acinar and ductal epithelial cells has been proposed to be a potential mechanism that impairs the secretion of salivary glands. In our study, two autoantigen-targeting microRNAs were characterized as antiapoptotic microRNAs functioning through apoptosis pathway, which may be potential targets for the treatment of pSS.

Abstract
Background Increasing evidence has demonstrated the importance of non-coding RNAs including long non-coding RNA (lncRNA) and microRNAs (miRNAs) in the tumorigenesis of osteosarcoma (OS). Abnormal expression of lncRNA olfactory receptor family 3 subfamily A member 4 (OR3A4) was found in multiple human cancers; however, the function of OR3A4 in OS remains largely unknown. Materials and Methods The expression level of OR3A4 in OS tissues and cell lines was detected by RT-qPCR. Cell counting kit-8 assay, colony formation and flow cytometry analysis were performed to determine the growth of OS cells. The targets of OR3A4 were predicted using the miRDB database. The binding between OR3A4 and miRNAs was confirmed by dual-luciferase reporter assay. Results OR3A4 was overexpressed in OS tissues and correlated with the advanced progression of OS patients. Down-regulation of OR3A4 significantly inhibited the proliferation and colony formation of OS cells. Mechanistically, OR3A4 acted as a sponge of miR-1207-5p. Glucose-6-phosphate dehydrogenase (G6PD) was identified as a target of miR-1207-5p. Knockdown of OR3A4 increased the expression of miR-1207-5p and consequently, suppressed the level of G6PD in OS cells. Due to the essential role of G6PD in the pentose phosphate pathway (PPP), depletion of OR3A4 inhibited NADPH production, glucose consumption and lactate generation. Decreased level of NADPH by depletion of OR3A4 up-regulated the redox state (ROS) content and resulted in endoplasmic reticulum (ER) stress in OS cells. Restoration of G6PD significantly attenuated the cell growth inhibition induced by OR3A4 knockdown. Conclusion Our finding suggested the critical role of OR3A4 in the proliferation of OS cells via targeting the miR-1207-5p/G6PD axis.

Abstract
Increasing evidences demonstrate that circular RNAs (circRNAs) are extensively implicated in various cancers including colorectal cancer (CRC). In the present study, we found that circRNA HIPK3 (circPIK3) was upregulated in CRC. We identified that circHIPK3 was closely related with unfavorable clinicopathological features in patients with CRC. Functional transwell assay and proliferation assay indicated that circHIPK3 served as an oncogene and promoted CRC cells migration, invasion and proliferation. Meanwhile, we found that formin like 2 (FMNL2) was a key downstream molecule in circHIPK3-induced metastasis and proliferation in CRC cells. We further verified that circHIPK3 was mainly located at cytoplasm through an immunofluorescence assay. An online bioinformatics screening and a GEO datasets analysis showed that microRNA 1207-5p (miR-1207-5p) was downregulated in CRC. Also, we found that miR-1207-5p shared a similar miR-1207-5p response elements (MREs-1207-5p). Meanwhile, we showed that miR-1207-5p suppressed CRC cells migration, invasion and proliferation via directly targeting of FMNL2. Even further, via a constructed luciferase assay, we indicated that circHIPK3 was another target of miR-1207-5p. Functionally, we proved that circHIPK3 enhanced FMNL2 mediated promotion of migration, invasion and proliferation by sponging of miR-1207-5p in CRC cells. In summary, the outcomes of this study illustrated that circHIPK3 promoted CRC cells migration, invasion and proliferation modulating of FMNL2 by sponging of miR-1207-5p. Our findings indicated that circHIPK3/miR-1207-5p/FMNL2 axis might be a new strategy in molecular treatment of CRC.

Abstract
We previously reported that miR-1207-5p can inhibit epithelial-mesenchymal transition (EMT) induced by growth factors such as EGF and TGF-β, but the exact mechanism is unclear. Here we identified that Colony stimulating factor 1 (CSF1) is a target gene of miR-1207-5p. CSF1 controls the production, differentiation and function of macrophage and promotes the release of proinflammatory chemokines. We showed that miR-1207-5p inhibited lung cancer cell A549 proliferation, migration and invasion in vitro, and suppressed the STAT3 and AKT signalings. miR-1207-5p overexpression can increase HUVEC angiogenesis, and can modulate the M2 phenotype of macrophage. miR-1207-5p also significantly inhibited A549 cells metastasis in a nude mouse xenograft model. miR-1207-5p and CSF1 expression levels and their relationship with lung cancer survival and metastasis status were assayed by means of a lung cancer tissue microarray. Macrophage is an essential part of the tumor microenvironment, thus the miR-1207-5p-CSF1 axis maybe a new regulator of lung cancer development through modulating the tumor microenvironment.

Abstract
Accumulating evidence indicates that ectopic expression of non‐coding RNAs are responsible for breast cancer progression. Increased non‐coding RNA PVT1, the host gene of microRNA‐1207‐5p (miR‐1207‐5p), has been associated with breast cancer proliferation. However, how PVT1 functions in breast cancer is still not clear. In this study, we show a PVT1‐derived microRNA, miR‐1207‐5p, that promotes the proliferation of breast cancer cells by directly regulating STAT6. We first confirm the positive correlated expression pattern between PVT1 and miR‐1207‐5p by observing consistent induced expression by estrogen, and overexpression in breast cancer cell lines and breast cancer patient specimens. Moreover, silence of PVT1 also decreased miR‐1207‐5p expression. Furthermore, increased miR‐1207‐5p expression promoted, while decreased miR‐1207‐5p expression suppressed, cell proliferation, colony formation, and cell cycle progression in breast cancer cell lines. Mechanistically, a novel target of miR‐1207‐5p,STAT6, was identified by a luciferase reporter assay. Overexpression of miR‐1207‐5p decreased the levels of STAT6, which activated CDKN1A and CDKN1B to regulate the cell cycle. We also confirmed the reverse correlation of miR‐1207‐5p and STAT6 expression levels in breast cancer samples. Therefore, our findings reveal that PVT1‐derived miR‐1207‐5p promotes the proliferation of breast cancer cells by targeting STAT6, which in turn controls CDKN1A and CDKN1B expression. These findings suggest miR‐1207‐5p might be a potential target for breast cancer therapy.

Abstract
OBJECTIVE The aim of this study was to investigate the association between miR-1207-5p expression in peripheral blood and the chemosensitivity of primary gallbladder carcinoma (PGBC). METHODS A total of 85 patients with PGBC undergoing preoperative chemotherapy were divided into effective (n=18) and ineffective (n=67) groups. Another 70 healthy individuals were selected as the control group. An miR-1207-5p mimic (mimic group), an inhibitor (inhibitor group), and a negative control (NC group) sequence were transfected into human gallbladder carcinoma GBC-SD cells. Real-time quantitative polymerase chain reaction was used to determine miR-1207-5p expression. After 48 hours of cisplatin treatment, CCK-8 method was used to detect cell proliferation and flow cytometry were performed to examine cell apoptosis. RESULTS miR-1207-5p expression in peripheral blood was significantly associated with tumor node metastasis staging of PGBC (P<0.05). Before chemotherapy, miR-1207-5p expression in patients was higher than in healthy individuals (P<0.05). After chemotherapy, the effective group had lower miR-1207-5p expression than the ineffective group (P<0.05). The rates of positive expression of Ki67 protein in the effective group were significantly lower than those in the ineffective group (P<0.05). Receiver operating characteristic curves showed that the area under curve, sensitivity, and specificity of miR-1207-5p used to diagnose PGBC were 0.898, 77.6%, and 97.1% at a cutoff of 1.470, respectively. After 48 hours of cisplatin treatment, compared with the NC group and nontransfected (non-T) group, the mimic group had decreased rates of cell inhibition and apoptosis, but the inhibitor group had increased rates (all P<0.05). The expression levels of caspase3 protein were increased in the mimic group and decreased in the inhibitor group. Cell survival rates in the mimic group at different time points after cisplatin treatment were significantly higher than the corresponding rates in the NC and non-T groups, whereas the cell survival rates in the inhibitor group were significantly lower than the rates in the NC and non-T groups (all P<0.05). The concentration and action time of cisplatin were negatively associated with the cell survival rate in each group (all P<0.05). CONCLUSION Cisplatin-based chemosensitivity of PGBC increased as expression of miR-1207-5p in peripheral blood declined. Thus, miR-1207-5p appears to be a promising and novel chemosensitizer for the treatment of PGBC.

Abstract
Although African‐Americans (AAs) have a higher incidence of colorectal cancer (CRC) than White people, the underlying biochemical mechanisms for this increase are poorly understood. The current investigation was undertaken to examine whether differences in self‐renewing cancer stem/stem‐like cells (CSCs) in the colonic mucosa, whose stemness is regulated by certain microRNAs (miRs), could partly be responsible for the racial disparity in CRC. The study contains 53 AAs and 47 White people. We found the number of adenomas and the proportion of CD44+CD166− CSC phenotype in the colon to be significantly higher in AAs than White people. MicroRNAs profile in CSC‐enriched colonic mucosal cells, expressed as ratio of high‐risk (≥3 adenomas) to low‐risk (no adenoma) CRC patients revealed an 8‐fold increase in miR‐1207‐5p in AAs, compared to a 1.2‐fold increase of the same in White people. This increase in AA was associated with a marked rise in lncRNA PVT1 (plasmacytoma variant translocation 1), a host gene of miR‐1207‐5p. Forced expression of miR‐1207‐5p in normal human colonic epithelial cells HCoEpiC and CCD841 produced an increase in stemness, as evidenced by morphologically elongated epithelial mesenchymal transition( EMT) phenotype and significant increases in CSC markers (CD44, CD166, and CD133) as well as TGF‐β, CTNNB1, MMP2, Slug, Snail, and Vimentin, and reduction in Twist and N‐Cadherin. Our findings suggest that an increase in CSCs, specifically the CD44+CD166− phenotype in the colon could be a predisposing factor for the increased incidence of CRC among AAs. MicroRNA 1207‐5p appears to play a crucial role in regulating stemness in colonic epithelial cells in AAs.
