MiRNA-296-5p promotes the sensitivity of nasopharyngeal carcinoma cells to cisplatin via targeted inhibition of STAT3/KLF4 signaling axis. Sci Rep 2024; 14:6681.

Abstract
Improving drug sensitivity is an important strategy in chemotherapy of cancer and accumulating evidence indicates that miRNAs are involved in the regulation of drug sensitivity, but the specific mechanism is still unclear. Our previous study has found that miR-296-5p was significantly downregulated in nasopharyngeal carcinoma (NPC). Here, we aim to explore whether miR-296-5p is involved in regulating cisplatin sensitivity in NPC by regulating STAT3/KLF4 signaling axis. The cell proliferation and clonogenic capacity of NPC cells were evaluated by CCK8 Assay and plate colony assay, respectively. The Annexin V-FITC staining kit was used to determine and quantify the apoptotic cells using flow cytometry. The drug efflux ability of NPC cells were determined by Rhodamine 123 efflux experiment. The expression of miR-296-5p, apoptosis-related genes and protein in NPC cell lines were detected by qPCR and Western blot, respectively. Animal study was used to evaluate the sensitivity of NPC cells to DDP treatment in vivo. Our results showed that elevated miR-296-5p expression obviously promoted the sensitivity of NPC cells to DDP by inhibiting cell proliferation and clonogenic capacity, and inducing apoptosis. In addition, we found that miR-296-5p inhibited the expression of STAT3 and KLF4 in NPC cells, while overexpression of exogenous STAT3 reversed miR-296-5p-mediated enhancement in cell death of DDP-treated NPC cells. In vivo studies further confirmed that miR-296-5p promotes the sensitivity of NPC cells to DDP treatment. miRNA-296-5p enhances the drug sensitivity of nasopharyngeal carcinoma cells to cisplatin via STAT3/KLF4 signaling pathway.

[PMID: 38372878 DOI: 10.1007/s12033-024-01054-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 01/02/2024] [Indexed: 02/20/2024]
Abstract
Sorafenib (SOR) is the first-line chemotherapeutic therapy for hepatocellular carcinoma (HCC) treatment, but SOR resistance is a key factor affecting the therapeutic effect. Emerging studies have suggested that circular RNAs (circRNAs) play an important role in the development of drug resistance in HCC cells. This paper aimed to elucidate the potential role and molecular mechanism of circRNA Scm polycomb group protein homolog 1 (circSCMH1) in SOR-resistant HCC cells. CircSCMH1, microRNA-485-5p (miR-485-5p), and hematological and neurological expressed 1 (HN1) contents were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell Counting Kit-8 (CCK8) assay was adopted to detect the SOR sensitivity of cells. Cell proliferation, migration, invasion, and apoptosis were assessed using colony formation, 5-Ethynyl-2'-deoxyuridine (EdU), transwell, and flow cytometry assays. Glucose metabolism was analyzed using commercial kits. HN1, B cell lymphoma-2 (Bcl-2), and Bcl-2-associated X (Bax) protein levels were assessed using western blot. Binding between miR-485-5p and circSCMH1 or HN1 was verified using a dual-luciferase reporter. Xenograft tumor model was used to explore the function of circSCMH1 in vivo. CircSCMH1 expression and HN1 abundances were increased, but the miR-485-5p level was reduced in SOR-resistant HCC tissues and cells. Deficiency of circSCMH1 enhanced SOR sensitivity by suppressing cell proliferation, migration, invasion, and glucose metabolism and inducing cell apoptosis in SOR-resistant HCC cell lines (Huh7/SOR and Hep3B/SOR). Mechanistically, circSCMH1 sponged miR-485-5p to positively regulate HN1 expression. Importantly, circSCMH1 depletion inhibited tumor growth and increased SOR sensitivity in vivo. CircSCMH1 promoted SOR resistance in HCC cells at least partly through upregulating HN1 expression by sponging miR-485-5p. These findings elucidated a new regulatory pathway of chemo-resistance in SOR-resistant HCC cells and provided a possible circRNA-targeted therapy for HCC.

Inhibiting specificity protein 1 attenuated sevoflurane-induced mitochondrial stress and promoted autophagy in hippocampal neurons through PI3K/Akt/mTOR and α7-nAChR signaling. Neurosci Lett 2023; 794:136995. [PMID: 36464148 DOI: 10.1016/j.neulet.2022.136995] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 11/17/2022] [Accepted: 11/28/2022] [Indexed: 12/03/2022]
Abstract
Sevoflurane, a commonly used anesthetic in surgery, is considered as an inducer of neurodegenerative diseases and postoperative complications including postoperative cognitive dysfunction. Evidence showed that specificity protein 1 (SP1) participated in the regulation of various cellular processes. Also, SP1 was found to modulate sevoflurane-induced hippocampal inflammatory injury both in vitro and in vivo. Our study aimed to illustrate the role of SP1 in mediating mitochondrial stress and autophagy in neurons under sevoflurane exposure. SiRNA for SP1 was transfected in to hippocampus neurons for the loss-of-function assay before sevoflurane stimulation. Meanwhile, recilisib was utilized for PI3K/Akt/mTOR signaling activation, GTS-21 and MLA (methylycaconitine citrate) were used to activate or inactivate alpha 7 nicotinic acetylcholine receptor (α7-nAChR), respectively. Sevoflurane induced SP1 upregulation and autophagy suppression. Interfering SP1 dramatically depressed the promoted oxidative stress and mitochondrial dysfunction induced by sevoflurane. Additionally, SP1 silence blocked sevoflurane-induced activation of PI3K/Akt/mTOR signaling and inhibition of α7-nAChR. Restoring PI3K/Akt/mTOR signaling or depressing CAP significantly reversed the repressive effects of SP1 knockdown on mitochondrial stress and autophagy imbalance in hippocampal cells. In conclusions, our research indicated that SP1 regulated sevoflurane-induced oxidative stress dysregulation, mitochondrial function and cell autophagy in hippocampus via mediating the PI3K/Akt/mTOR and α7-nAChR pathways. Therefore, it might provide a novel sight for sevoflurane-induced hippocampus injury and POCD therapy.

Abstract
Literature reports that lncRNA KCNQ1OT1 is markedly up-regulated in cervical cancer (CC) tissues and cell lines, and KCNQ1OT1 can promote the proliferation and metastasis of CC cells. This current work was designed to investigate the molecular mechanism underlying the participation of KCNQ1OT1 in CC progression. Herein, RT-qPCR was utilized for determining the levels of KCNQ1OT1, miR-296-5p and HYOU1 in clinical tumor tissue specimens and CC cell lines. Then, starBase predicted the complementary binding sites of KCNQ1OT1 and miR-296-5p or miR-296-5p and HYOU1. Dual-luciferase reporter assay/RIP assay validated the interplays among KCNQ1OT1/miR-296-5p/HYOU1. In addition, CCK-8, wound healing and transwell assays were employed to assess the proliferative, migrative and invasive properties of CC cells. Moreover, nude mice xenograft model was established by subcutaneously injection with SiHa cells in order to validate the precise functions of KCNQ1OT1/miR-296-5p/HYOU1 axis in CC in vivo. Besides, Immunohistochemical staining examined Ki-67 expression in xenograft tumors and western blotting analysis detected expressions of MMP2/9 and Wnt/β-catenin signaling pathway in CC cells and xenograft tumors. Elevated KCNQ1OT1 and HYOU1 as well as reduced miR-296-5p were observed in clinical tumor tissue specimens and CC cell lines. Results revealed that upregulation of miR-296-5p counteracted the enhancing effects of overexpressed KCNQ1OT1 on the proliferative, migrative and invasive abilities of CC cells. Additionally, HYOU1 overexpression abolished the suppressing effects of silenced KCNQ1OT1 on the malignant behaviors of CC cells and tumor growth. To conclude, KCNQ1OT1 could aggravate the malignant behaviors of CC and facilitate tumor growth through modulating miR-296-5p/HYOU1 axis.

Abstract
N‑methyl D‑aspartate receptors (NMDARs) are closely associated with the development, growth and metastasis of cancer. Glutamate receptor, ionotropic, N‑methyl D‑aspartate‑associated protein 1 (GRINA) is a member of the of the NMDAR family, and its aberrant expression is associated with gastric cancer. However, the role of GRINA in colorectal cancer (CRC) is not completely understood. In the present study, expression profiles of GRINA in several CRC databases were obtained and further verified using clinical CRC samples. The effects of GRINA overexpression on CRC progression both in vivo and in vitro were assessed. Briefly, cell proliferation was detected using MTT assay, and cell migration and invasion ability were evaluated by wound healing and Transwell assay. In addition, the molecular mechanism underlying the upregulated expression of GRINA in CRC was investigated. The regulatory association between GRINA and miR‑296‑3p was detected by luciferase assay, reverse transcription‑quantitative PCR and western blotting. The results demonstrated that GRINA expression levels were significantly increased in tumor samples compared with those in healthy samples, and upregulated expression of GRINA was associated with a less favorable prognostic outcome in patients with CRC. GRINA overexpression significantly increased CRC cell proliferation, invasion and migration. Additionally, it was determined that GRINA was post‑transcriptionally regulated by microRNA (miR)‑296‑3p. Together, the results of the present study suggested the potential importance of the miR‑296‑3p/GRINA axis and highlighted potential novel targets for the management of CRC.

Abstract
Long noncoding RNAs (lncRNAs) have drawn growing attention due to their regulatory roles in various diseases, including tumors. Recently, lncRNA FOXD3 antisense RNA 1 (FOXD3-AS1) was shown to be overexpressed in colon adenocarcinoma and glioma, exerting oncogenic functions. However, its expression and effects in cervical cancer (CC) remained unknown. In this research, our group first reported that the levels of FOXD3-AS1 were distinctly elevated in CC samples and cell lines. The distinct upregulation of FOXD3-AS1 was associated with lymphatic invasion, distant metastasis, and International Federation of Gynecology and Obstetrics stage, and also predicted poor clinical results of CC patients. Next, transcription factor SP1 was demonstrated to resulting in the upregulation of FOXD3-AS1 in CC. Functional assays indicated that knockdown of FOXD3-AS1 distinctly suppressed CC progression via affecting cell proliferation, cell apoptosis, and metastasis. Moreover, mechanistic studies suggested that FOXD3-AS1 acted as an endogenous sponge by directly binding miR-296-5p, resulting in the suppression of miR-296-5p. In addition, we also reported that high mobility group A, a direct target of miR-296-5p, could mediate the tumor-promotive effects that FOXD3-AS1 displayed. Overall, our present study might help to lead a better understanding of the pathogenesis of CC, provide a novel possible tumor biomarker, and probe the feasibility of lncRNA-directed treatments for CC.

JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2020; 39:248. [PMID: 33203425 PMCID: PMC7670781 DOI: 10.1186/s13046-020-01720-w] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Accepted: 09/25/2020] [Indexed: 12/20/2022]
Abstract
Background The mechanism of histone deacetylase 3 (HDAC3) in colorectal cancer (CRC) has already been discussed. However, the feedback loop of HDAC3/microRNA (miR)-296-3p and transforming growth factor β-induced factor 1 (TGIF1) in CRC has not been explained clearly. Thus, the mainstay of this study is to delve out the mechanism of this axis in CRC. Methods To demonstrate that HDAC3 regulates the miR-296-3p/TGIF1/TGFβ axis and is involved in CRC progression, a series of cell biological, molecular and biochemical approaches were conducted from the clinical research level, in vitro experiments and in vivo experiments. These methods included RT-qPCR, Western blot assay, cell transfection, MTT assay, EdU assay, flow cytometry, scratch test, Transwell assay, dual luciferase reporter gene assay, chromatin immunoprecipitation, nude mouse xenograft, H&E staining and TUNEL staining. Results Higher HDAC3 and TGIF1 and lower miR-296-3p expression levels were found in CRC tissues. HDAC3 was negatively connected with miR-296-3p while positively correlated with TGIF1, and miR-296-3p was negatively connected with TGIF1. Depleted HDAC3 elevated miR-296-3p expression and reduced TGIF1 expression, decreased TGFβ pathway-related proteins, inhibited CRC proliferation, invasion, and migration in vitro and slowed down tumor growth and induction of apoptosis in vivo, which were reversed by miR-296-3p knockdown. Restored miR-296-3p suppressed TGIF1 and reduced TGFβ pathway-related proteins, inhibited CRC proliferation, invasion, and migration in vitro and slowed down tumor growth and induction of apoptosis in vivo, which were reversed by TGIF1 overexpression. Conclusion This study illustrates that down-regulation of HDAC3 or TGIF1 or up-regulation of miR-296-3p discourages CRC cell progression and slows down tumor growth, which guides towards a novel direction of CRC treatment.

Abstract
Aim To explore the effect of miR-296-5p on the metastasis of nasopharyngeal carcinoma (NPC) cells and investigate the underlying mechanism. Methods The expressions of miR-296-5p in NPC tissues and cells were determined using GSE32920 database analysis and real-time PCR and miRNA microarray assays. An miR-296-5p mimic and inhibitor were transfected into NPC cells. Then, immunofluorescence imaging, scratch wound-healing, transwell migration and invasion assays were used to observe the effects of miR-296-5p on cell metastasis and invasion. Real-time PCR and western blotting were carried out to detect the expressions of genes and proteins related to epithelial–mesenchymal transition (EMT). A dual luciferase reporter assay was used to identify whether TGF-β is the target gene of miR-296-5p. Finally, TGF-β expression plasmids were transfected into NPC cells to verify the role of TGF-β in the miR-296-5p-mediated inhibition of nasopharyngeal carcinoma cell metastasis. Results Our results show that miR-296-5p inhibits the migratory and invasive capacities of NPC cells by targeting TGF-β, which suppresses EMT. Importantly, the miR-296-5p level was significantly lower in human NPC tissues than in adjacent normal tissues. It also negatively correlated with TGF-β and was significantly associated with the lymph node metastasis of patients with NPC. Conclusions Our findings show that miR-296-5p represses the EMT-related metastasis of NPC by targeting TGF-β. This provides new insight into the role of miR-296-5p in regulating NPC metastasis and invasiveness.

Abstract
Colon adenocarcinoma (COAD) is the most common type of gastrointestinal cancer and is still the third leading cause of cancer-related mortality worldwide. Therefore, finding new and promising drugs to eradicate cancer may be a feasible method to treat COAD patients. Cys2-His2 zinc finger proteins (ZFPs) is one of the largest transcription factor family and many of them are highly involved in regulation of cell differentiation, proliferation, apoptosis, and neoplastic transformation. In this study, we identified a tumor-inhibiting factor, ZNF549, which expressed lowly in COAD tissues and COAD cell lines (HT29, HCT116, SW480, LoVo, and SW620). Overexpression of ZNF549 inhibit the ability of COAD cell proliferation and migration. On the contrary, decreasing the ZNF549 expression level promote the ability of COAD cell proliferation and migration. Through bioinformatics analysis, we found that ZNF549 was a potential target of hsa-miR-708-5p (miR-708-5p). Furthermore, we verified the possibility of miR-708-5p targeting the ZNF549 gene, and miR-708-5p inhibited the expression of ZNF549 by luciferase reporter assays, qRT-PCR and western blot assays. Moreover, the relationship between miR-708-5p and phosphatidylinositol 3-kinase/AKt (PI3K/AKt) signal pathway was elucidated. Overexpression and inhibition of miR-708-5p resulted in increased and decreased expression of p-AKt and p-PI3K in HCT116 cells, respectively. RT-qPCR and western blot assays results demonstrated that miR-708-5p regulated COAD cells development by promoting the process of Epithelial-mesenchymal transition (EMT) through PI3K/AKt signaling pathway. In summary, our findings demonstrated that ZNF549, the target gene of miR-708-5p, functions as a tumor suppressor to inhibit COAD cell lines proliferation and migration through regulate the PI3K/AKt signal pathway.

Abstract
Cancer and organ injury-such as that occurring in the perioperative period, including acute lung injury, myocardial infarction, and acute gut injury-are among the leading causes of death in the United States and impose a significant impact on quality of life. MicroRNAs (miRNAs) have been studied extensively during the last two decades for their role as regulators of gene expression, their translational application as diagnostic markers, and their potential as therapeutic targets for disease treatment. Despite promising preclinical outcomes implicating miRNA targets in disease treatment, only a few miRNAs have reached clinical trials. This likely relates to difficulties in the delivery of miRNA drugs to their targets to achieve efficient inhibition or overexpression. Therefore, understanding how to efficiently deliver miRNAs into diseased tissues and specific cell types in patients is critical. This review summarizes current knowledge on various approaches to deliver therapeutic miRNAs or miRNA inhibitors and highlights current progress in miRNA-based disease therapy that has reached clinical trials. Based on ongoing advances in miRNA delivery, we believe that additional therapeutic approaches to modulate miRNA function will soon enter routine medical treatment of human disease, particularly for cancer or perioperative organ injury. SIGNIFICANCE STATEMENT: MicroRNAs have been studied extensively during the last two decades in cancer and organ injury, including acute lung injury, myocardial infarction, and acute gut injury, for their regulation of gene expression, application as diagnostic markers, and therapeutic potentials. In this review, we specifically emphasize the pros and cons of different delivery approaches to modulate microRNAs, as well as the most recent exciting progress in the field of therapeutic targeting of microRNAs for disease treatment in patients.

Abstract
The human Periodontal Ligament Stem Cells (hPDLSCs) exhibit self-renewal capacity and clonogenicity potential. The Extracellular Vesicles (EVs) secreted by hPDLSCs are particles containing lipids, proteins, mRNAs, and non-coding RNAs, among which microRNAs, that are important in intercellular communication. The purpose of this study was the analysis of the non-coding RNAs contained in the EVs derived from hPDLSCs using Next Generation Sequencing. Moreover, our data were enriched using bioinformatic tools. The analysis highlighted the presence of non-coding RNAs and five microRNAs: MIR24-2, MIR142, MIR335, MIR490, and MIR296. Our results show that these miRNAs target the genes classified in two terms of the Gene Ontology: "Ras protein signal transduction" and "Actin/microtubule cytoskeleton organization." Noteworthy, the in-deep analysis of our EVs highlights that the miRNAs could be implicated in the silencing of proto-oncogenes involved in 12 different types of tumors.

Abstract
The aberrant expression of microRNAs (miRNAs) is involved in the initiation and progression of human cancers. In our study, we found that miR-539 was down-regulated in breast cancer tissues and cell lines. Decreased expression of miR-539 was significantly associated with lymph node metastasis in patients with breast cancer. Overexpression of miR-539 inhibited the proliferation and promoted apoptosis of breast cancer cells. Moreover, highly expressed miR-539 significantly suppressed the epithelial-mesenchymal transition (EMT) and sensitized cells to cisplatin treatment. Mechanistically, miR-539 was found to target the specificity protein 1 (SP1) and down-regulated the expression of SP1 in breast cancer cells. Knockdown of miR-539 consistently increased the expression of SP1. The expression of miR-539 in breast cancer tissues was negatively correlated with the expression of SP1. Restoration of SP1 significantly attenuated the inhibitory effect of miR-539 on the proliferation of breast cancer cells. Taken together, our results indicate that miR-539 has a tumor suppressive role in breast cancer via targeting SP1, suggesting miR-539 as a promising target for the diagnosis of breast cancer.

Abstract
Glioblastoma is the most aggressive malignant brain tumor in adults. Long noncoding RNA HOTAIRM1 (HOX antisense intergenic RNA myeloid 1) has been reported to participate in the progression of various cancers. However, the role of HOTAIRM1 in glioblastoma and its underlying mechanisms are largely unknown. The relative expression levels of HOTAIRM1, miR-137 and specificity protein 1 were detected by quantitative real-time PCR or western blot. The effects of HOTAIRM1 on cell proliferation and invasion were evaluated by Cell Counting Kit-8 assay and Transwell assay, respectively. The interactions among HOTAIRM1, miR-137 and specificity protein 1 were predicted by online softwares and confirmed by luciferase reporter assay and RNA immunoprecipitation assay. The levels of HOTAIRM1 and specificity protein 1 were significantly increased while miR-137 was significantly decreased in glioblastoma tissues and cells. Knockdown of HOTAIRM1 suppressed proliferation and invasion in glioblastoma cells. Moreover, miR-137 was bound to HOTAIRM1, and specificity protein 1 was identified as a target of miR-137. The protein level of specificity protein 1 was repressed by silencing the expression of HOTAIRM1, whereas the effect was restored by inhibiting the expression of miR-137. Downregulation of HOTAIRM1 expression suppressed the proliferation and invasion of glioblastoma cells by down-regulating specificity protein 1 expression via sponging miR-137, indicating a promising strategy for glioblastoma treatment.

Abstract
Non-small-cell lung cancer (NSCLC) is the most common cause of cancer-associated mortality worldwide. MicroRNAs (miRs) are a class of small non-coding RNAs that are commonly dysregulated in human cancer. The aim of the current study was to evaluate the effect of miR-296-3p on the cell migration and invasion of NSCLC. Pairs of tumor tissues and para-cancerous tissues (n=50) were collected from patients with NSCLC, and the expression of miR-296-3p was analyzed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Additionally, tumor cell viability, migration and invasion were examined in vitro using Cell Counting Kit-8, wound healing and Matrigel assays, respectively. Furthermore, potential targets of miR-296-3p were screened for using TargetScan and validated using a dual-luciferase reporter assay. The expression levels of phosphoinositide-3-kinase (PI3K), AKT serine/threonine kinase (AKT), mammalian target of rapamycin (mTOR), matrix metallopeptidase 2 (MMP2) and SRY-box 4 (SOX4) were detected by RT-qPCR and western blot analysis. The data indicated that miR-296-3p was downregulated in tumor tissues compared with adjacent normal tissues. Overexpression of miR-296-3p inhibited NSCLC cell viability, migration and invasion in vitro. Furthermore, apurinic/apyrimidinic endodeoxyribonuclease 1 (APEX1) was identified as a direct target of miR-296-3p. APEX1 expression was upregulated in tumor tissues compared with para-cancerous tissues, and the mRNA and protein expression levels of APEX1 were decreased following transfection of NSCLC cells with miR-296-3p mimics compared with control cells. Additional investigations revealed that miR-296-3p was involved in regulating the PI3K/AKT/mTOR signaling pathway, and miR-296-3p mimics decreased the mRNA and protein expression levels of MMP2 and SOX4. In summary, the findings demonstrated that miR-296-3p may function as a tumor suppressor, and inhibits the migration and invasion of NSCLC cells by targeting APEX1. miR-296-3p is therefore a potential therapeutic molecular modulator of NSCLC.

Abstract
Cervical cancer is as a kind of cancer beginning from the cervix. Given that cervical cancer could be observed in women who infected with papillomavirus, regular oral contraceptives, and multiple pregnancies. Early detection of cervical cancer is one of the most important aspects of the therapy of this malignancy. Despite several efforts, finding and developing new biomarkers for cervical cancer diagnosis are required. Among various prognostic, diagnostic, and therapeutic biomarkers, miRNA have been emerged as powerful biomarkers for detection, treatment, and monitoring of response to therapy in cervical cancer. Here, we summarized various miRNAs as an employable platform for prognostic, diagnostic, and therapeutic biomarkers in the treatment of cervical cancer.

Abstract
Cervical cancer (CC) with early metastasis of the primary tumor results in poor prognosis and poor therapeutic outcomes. MicroRNAs (miRNAs) are small, noncoding RNA molecules that play a substantial role in regulating gene expression post-transcriptionally and influence the development and progression of tumors. Numerous studies have discovered that miRNAs play significant roles in the invasion and metastasis of CC by affecting specific pathways, including Notch, Wnt/β-catenin, and phosphoinositide-3 kinase (PI3K)-Akt pathways. miRNAs also effectively modulate the process of epithelial–mesenchymal transition. Many studies provide new insights into the role of miRNAs and the pathogenesis of metastatic CC. In this review, we will offer an overview and update of our present understanding of the potential roles of miRNAs in metastatic CC.

Abstract
Peritoneal fibrosis (PF) represents a well-recognized complication associated with continuous ambulatory peritoneal dialysis therapy, characterized by a reversible epithelial-to-mesenchymal transition (EMT) at the early stage. The aim of the current study was to investigate the effects linked with the long noncoding RNA (lncRNA) AK089579 on the EMT of peritoneal mesothelial cells (PMCs) as well as the associated regulatory mechanisms of AK089579 downstream of tyrosine kinase 2 (DOK2) and microRNA-296-3p (miR-296-3p). Enrichment analysis, gene intersection association analysis, and a gene-gene intersection network were initially constructed to ascertain whether AK089579 regulated the expression of DOK2 through the mediation of miR-296-3p via the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway in PF. After the PF mouse model had been constructed, the expression of the proteins associated with the JAK2/STAT3 signaling pathway and EMT and PMC migration and invasion were all determined accordingly. Based on the obtained results, AK089579 was determined to function as a competing endogenous RNA for miR-296-3p while acting to up-regulate the expression of DOK2, which is a target gene of miR-296-3p. AK089579 was detected to confer an inhibitory effect on the activation of the JAK2/STAT3 signaling pathway, whereby the migration and invasion of PMCs among the mice models were suppressed. Meanwhile, up-regulated miR-296-3p and down-regulated DOK2 produced contrasting effects when compared with the aforementioned findings. Treatment with wp10066, a JAK2/STAS3 signaling pathway inhibitor, was shown to reverse the effects exerted by up-regulated miR-296-3p. Taken together, the central findings of the current study present evidence highlighting the capability of the lncRNA AK089579 to bind competitively to miR-296-3p and indirectly enhance the expression of DOK2, which in turn suppresses the activation of the JAK2/STAT3 signaling pathway, whereby the EMT, migration, and invasion of PMCs was inhibited in PF.-Zhang, X. W., Wang, L., Ding, H. Long noncoding RNA AK089579 inhibits epithelial-to-mesenchymal transition of peritoneal mesothelial cells by competitively binding to microRNA-296-3p via DOK2 in peritoneal fibrosis.

[PMID: 30474556 PMCID: PMC6260849 DOI: 10.1186/s40659-018-0200-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2018] [Accepted: 11/18/2018] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Emerging evidence showed that microRNAs (miRs) play critical roles in human cancers by functioning as either tumor suppressor or oncogene. MIR-382 was found to function as tumor suppressor in certain cancers. However, the role of MIR-382 in colorectal cancer (CRC) is largely unknown. Specificity protein 1 (SP1) is highly expressed in several cancers including CRC and is correlated with poor prognosis, but it is unclear whether or not MIR-382 can regulate the expression of SP1. METHODS MIR-382 expression level was measured by reverse transcription-quantitative polymerase chain reaction. The connection between MIR-382 and SP1 was validated by luciferase activity reporter assay and western blot assay. Cell counting kit-8 assay and wound-healing assay were conducted to investigate the biological functions of MIR-382 in CRC. RESULTS In this study, we found MIR-382 expression was downregulated in CRC tissues and cell lines, and the transfection of MIR-382 mimic decreased cell growth and migration. Furthermore, we identified SP1 was a direct target of MIR-382. Overexpression of MIR-382 decreased the expression of SP1, whereas MIR-382 knockdown promoted SP1 expression. We also observed an inversely correlation between MIR-382 and SP1 in CRC tissues. Additionally, we showed that knockdown of SP1 inhibited cell growth and migration and attenuated the effect of MIR-382 inhibitor on cell behaviors. CONCLUSIONS In conclusion, the present study describes a potential mechanism underlying a MIR-382/SP1 link contributing to CRC development. Thus, MIR-382 may be able to be developed as a novel treatment target for CRC.

Jiang H, Huang G, Zhao N, Zhang T, Jiang M, He Y, Zhou X, Jiang X. Long non-coding RNA TPT1-AS1 promotes cell growth and metastasis in cervical cancer via acting AS a sponge for miR-324-5p. J Exp Clin Cancer Res 2018; 37:169. [PMID: 30045766 PMCID: PMC6060520 DOI: 10.1186/s13046-018-0846-8] [Citation(s) in RCA: 68] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Accepted: 07/16/2018] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Increasing studies confirmed that abnormal lncRNAs expression play a critical role in cervical cancer (CC) development and progression. LncRNA TPT1-AS1, a novel lncRNA, its role and underlying mechanisms involved in CC remain largely unknown. METHODS Colony formation, EdU and Transwell assays were used to determine colony formation, proliferation, migration and invasion in vitro. The subcutaneous tumor model and tail vein injection lung metastasis model were performed to check tumor growth and metastasis in vivo. Luciferase activity and RIP experiment were carried out to determine the interaction between miR-324-5p and TPT1-AS1. RESULTS We demonstrated for the first time that TPT1-AS1 expression was up-regulated in CC tissues and cell lines. High TPT1-AS1 was significantly correlated with adverse prognostic characteristics and poor survival. TPT1-AS1 overexpression and knockdown experiments revealed that TPT1-AS1 promoted cell colony formation, proliferation, migration, invasion and EMT progression of CC cells in vitro and in vivo. The underlying mechanism indicated that TPT1-AS1 functioned as an endogenous sponge for miR-324-5p in CC cells. Gain- and loss- experiment confirmed that miR-324-5p inhibited cell colony formation, proliferation, migration, invasion and EMT progression of CC cells, and mediated the biological effects of TPT1-AS1. Further investigations confirmed that SP1 was a direct target of miR-324-5p and mediated the effects of TPT1-AS1 and miR-324-5p in CC. CONCLUSIONS We demonstrated for the first time that TPT1-AS1 as an oncogenic lncRNA in CC progression and as a potential target for CC cure.

Abstract
Cervical cancer is a common malignant cancer among women worldwide. Changes in the vaginal microecological environment lead to multiple gynecological diseases, including cervical cancer. Recent research has shown that Lactobacillus may play an important role in the occurrence and development of cervical cancer. This review explores the role of Lactobacillus in cervical cancer. A total of 29 articles were included after identification and screening. The pertinent literature on Lactobacillus in cervical cancer from two perspectives, including clinical studies and experimental studies, was analyzed. An association network for the mechanism by which Lactobacillus induces cervical cancer was constructed. In addition, we provide direction and insight for further research on the role of Lactobacillus in cervical cancer.

Abstract
Glioma has been considered as one of the most prevalent and common malignancy of the nervous system; however, the underlying mechanisms that are responsible for the occurrence and development of glioma still remain largely unknown. Amounting evidence highlights the critical regulatory function of miRNAs in carcinogenesis. Here, we showed that the expression of miR-150-3p was significantly decreased in glioma tissues and cell lines. Suppressed expression of miR-150-3p was associated with the lymph node metastasis of the glioma patients. Overexpression of miR-150-3p significantly inhibited the proliferation of glioma cells. Molecular study uncovered that the transcription factor specificity protein 1 (SP1) was identified as one of the targets of miR-150-3p Highly expressed miR-150-3p in glioma cells significantly decreased both the mRNA and protein levels of SP1. Consistently, the abundance of phosphatase and tension homolog deleted on chromosome ten (PTEN), a negative downstream target of SP1, was increased with the ectopic miR-150-3p Collectively, these results suggested that miR-150-3p suppressed the growth of glioma cells partially via regulating SP1 and possibly PTEN.
