Abstract
BACKGROUND Ferroptosis is involved in osteoarthritis development; however, the roles of long noncoding RNAs (lncRNAs), including lncRNA MEG3, in the regulation of ferroptosis in osteoarthritis are still unclear. METHODS In this study, qRT‒PCR and Western blotting assays were used to detect the expression of lncRNA MEG3, miR-885-5p, SLC7A11 and GPX4; MDA and CCK-8 assays were applied to analyse cellular MDA levels and cell viability, respectively. RESULT Erastin elevated cellular MDA levels and decreased the viability of chondrocytes and the erastin-induced decline in cell viability was reversed by a ferroptosis inhibitor (ferrostatin-1). Erastin downregulated lncRNA MEG3, SLC7A11 and GPX4 and upregulated miR-885-5p. Silencing of lncRNA MEG3 increased miR-885-5p and downregulated SLC7A11 and GPX4 and further sensitized chondrocytes to erastin-induced ferroptosis. In contrast, overexpression of lncRNA MEG3 had opposite effects. Dual luciferase assays confirmed binding between lncRNA MEG3 and miR-885-5p and between miR-885-5p and the 3'UTR of SLC7A11. In the synovial fluids from patients with osteoarthritis compared with synovial fluids from normal controls, the RNA levels of lncRNA MEG3 and SLC7A11 were decreased and the miR-885-5p expression level was increased. CONCLUSION Our findings indicated that lncRNA MEG3 overexpression alleviated ferroptosis in chondrocytes by affecting the miR-885-5p/SLC7A11 signalling pathway.

Abstract
INTRODUCTION The regulatory network of competing endogenous RNAs (ceRNAs) affects tumorigenesis. In this study, we aimed to investigate the mechanism by which long noncoding RNA HOXA-AS2 promotes prostate cancer (PCa) progression. METHODS The expression levels of HOXA-AS2, miR-885-5p, and KDM5B in PCa tissues and cell lines were evaluated by qRT-PCR or Western blotting. CCK-8 assay, caspase-3 activity assay, flow cytometry, and scratch test revealed changes in cell proliferation, caspase-3 activity, apoptosis, and migration, respectively. Luciferase and radioimmunoprecipitation assays were used to evaluate the correlation among HOXA-AS2, miR-885-5p, and KDM5B expression profiles. RESULTS HOXA-AS2 expression level was elevated in PCa tissues and cells. Silencing of HOXA-AS2 suppressed proliferation and migration and facilitated apoptosis in PCa cells. HOXA-AS2 competitively adsorbed miR-885-5p, thereby blocking the effect of HOXA-AS2 knockdown by the miR-885-5p inhibitor in PCa cells. Moreover, KDM5B, a target of miR-885-5p, neutralized the function of miR-885-5p in PCa cells. CONCLUSION This study revealed a potential ceRNA regulatory pathway in which HOXA-AS2 affects KDM5B expression levels by sponging miR-885-5p to promote PCa development and progression.

Abstract
Background Circular RNAs (circRNAs) are implicated in carcinogenesis, including papillary thyroid cancer (PTC). Despite of previous reports regarding the high expression of circPTPRM in PTC, the role and regulatory mechanism remain to be investigated. Methods CircPTPRM and miR‐885‐5p expression were examined, and the effects on cell proliferation, migration, and invasion were also measured. Immunoblotting was performed to evaluate DNA methyltransferase 3A (DNMT3A) and the epithelial‐mesenchymal transition (EMT)‐associated proteins. Results CircPTPRM was overexpressed in PTC tissues and cell lines, which predicted poor prognosis. CircPTPRM inhibition significantly alleviated the proliferation, migration, and invasion abilities. It was subsequently confirmed that circPTPRM competed with miR‐885‐5p for DNMT3A binding. CircPTPRM promoted PTC progression via miR‐885‐5p/DNMT3A signal axis. Conclusion Our data elucidated that circPTPRM may play an oncogenic role in PTC through circPTPRM/miR‐885‐5p/DNMT3A axis

Abstract
CircSERPINA3 has been shown to be upregulated in laryngeal squamous cell carcinoma (LSCC); however, whether it regulates the development of LSCC and the specific molecular mechanism remains unclear, which is to be explored in this study. Expressions of circSERPINA3, miR-885-5p, and Malic enzyme 1 (ME1) in LSCC tissues or cell lines were determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR). The regulation of circSERPINA3 on the biological behavior of LSCC cells was confirmed by loss and gain experiments (cell counting kit-8, transwell, and colony formation assay). The correlation between circSERPINA3/ME1 and miR-885-5p was predicted and confirmed by bioinformatics analysis, dual-luciferase reporter assay, and qRT-PCR. The effect of circSERPINA3/miR-885-5p axis on the biological behavior of LSCC cells and expressions of epithelial-mesenchymal transition-related proteins was confirmed by rescue experiments. CircSERPINA3 and ME1 was upregulated in LSCC tissues, whereas miR-885-5p was downregulated. MiR-885-5p was the target gene of circSERPINA3, whereas ME1 was the target gene of miR-885-5p. Silent circSERPINA3 suppressed viability, invasion, migration, colony formation, and expression of ME1, claudin-4, snail, and vimentin but elevated expression of miR-885-5p and E-cadherin, whereas overexpressed circSERPINA3 was the opposite. However, miR-885-5p inhibitor or mimic reversed the effects of silent circSERPINA3 or overexpressed circSERPINA3. Collectively, circSERPINA3 promotes proliferation, migration, and invasion of LSCC cells by targeting miR-885-5p.

Abstract
Alzheimer's disease (AD) is a chronic degenerative disease in the central nervous system and circular RNAs (circRNAs) are identified as essential regulators in AD. The current research was designed for exploration of circ_0003611 in AD. Circ_0003611 was overexpressed in AD patients and Aβ-treated SK-N-SH cells. Aβ-induced apoptotic, inflammatory and oxidative damages were relieved after knockdown of circ_0003611. MiR-885-5p was validated as a miRNA target of circ_0003611. The protective function of circ_0003611 downregulation was achieved by releasing miR-885-5p in Aβ-treated SK-N-SH cells. KREMEN1 was a downstream gene of miR-885-5p. Overexpression of miR-885-5p attenuated the Aβ-triggered cell injury by reducing the KREMEN1 expression. KREMEN1 was regulated by circ_0003611 via sponging miR-885-5p in Aβ-treated SK-N-SH cells. These experimental data demonstrated that circ_0003611 enhanced the Aβ-induced neuronal cell injury in AD by serving as the miR-885-5p sponge to regulate the level of KREMEN1.

Abstract
PURPOSE Cholangiocarcinoma (CCA) is the second most malignant tumor of the hepatobiliary system. Due to its cumbersome early diagnosis and rapid progression, chemotherapy has become the main treatment option. Primary drug resistance is a major cause of the poor efficacy of chemotherapeutic drugs. Therefore, it is considered urgent to explore new drugs to overcome primary drug resistance of CCA. METHODS Western blot and qRT-PCR assays were used to assess the expression of myotrophin (MTPN) and microRNA-885-5p (miR-885-5p) in CCA tissues and cells. The viability of CCA cells treated with arsenic trioxide (ATO), 5-fluorouracil (5-Fu) and cisplatin (CDDP) was analyzed using a CCK-8 assay. A luciferase reporter assay was used to assess the interaction between miR-885-5p and MTPN. Kaplan-Meier analyses were used for survival assessments. RESULT We found that ATO can reduce the resistance of CCA cells to 5-Fu and CDDP and promote the killing effect of 5-Fu and CDDP. Low-dose ATO showed an anti-drug-resistance effect through up-regulation of the expression of miR-885-5p. Combined with sequencing results and database predictions, we found that MTPN may serve as a direct target of miR-885-5p. After MTPN knockdown, the sensitivity of CCA cells to 5-FU and CDDP was increased. Finally, we found that ATO can reverse chemotherapy resistance induced by overexpression of MTPN. CONCLUSION Our data indicate that the ATO/miR-885-5p/MTPN axis may serve as a target for improving the sensitivity of CCA cells to chemotherapy.

Abstract
Several studies have reported that miR-885-5p was dysregulated in a variety of cancers. However, there are few studies on the biological function of miR-885-5p in gastric cancer (GC). In this study, we investigated the biological function and underlying mechanism of miR-885-5p in GC. Quantitative real-time PCR was used to examine the expression of miR-885-5p in GC. Bioinformatics analysis was used to predict the target of miR-885-5p and confirmed using the luciferase reporter assay. Wound-healing and Transwell assay were conducted to evaluate the biological function of miR-885-5p and malic enzyme 1 (ME1). Western blotting was used to assess molecular changes. Hepatic and lung metastasis models were constructed and used to verify the role of miR-885-5p. We found that the expression of miR-885-5p was significantly downregulated in GC. Overexpression of miR-885-5p inhibited invasion and metastasis of GC in vivo and in vitro, while inhibition of miR-885-5p has the opposite result in vitro. ME1 is a direct target of miR-885-5p, overexpressed in GC, associated with poor prognosis. Overexpression of miR-885-5p negatively regulates ME1 and causes changes in downstream molecules Vimentin and Fibronectin. Our research found that miR-885-5p plays a tumor suppressor gene and could potentially serve as a biomarker and therapeutic target in GC.

Abstract
Background LncRNA HOXA-AS2 has been found in the literature to deteriorate glioblastoma. However, its regulatory mechanism is yet to be fully investigated. Our study focused chiefly on the interaction and role of the HOXA-AS2/miR-885-5p/RBBP4 axis in the development of glioblastoma. Methods qRT-PCR analysis was performed to detect the expression of lncRNA, miRNA and mRNA in glioblastoma tissues and cells. Dual-luciferase assay, RIP assay and RNA pull-down assay were later carried out to reveal the interactions among HOXA-AS2, miR-885-5p and RBBP4. After that, CCK-8 assay, BrdU assay, nude mice xenografting assay, western blot assay, and flow cytometry were carried out to analyze the effect of the HOXA-AS2/miR-885-5p/RBBP4 axis on glioblastoma samples. Results HOXA-AS2 and RBBP4 were found to be overexpressed in glioblastoma. Experimental results showed that HOXA-AS2 and RBBP4 contributed to the tumorigenesis of glioblastoma cells. However, miR-885-5p was observed to be downregulated in glioblastoma. Findings also indicated that HOXA-AS2 could negatively regulate miR-885-5p, thereby enhancing RBBP4 expression. Conclusion Overall, HOXA-AS2 promoted the tumorigenesis of glioblastoma by targeting and regulating miR-885-5p to induce the expression of RBBP4.

Abstract
The incidence of intrahepatic cholangiocarcinoma (iCCA) continues to increase worldwide, however its molecular pathogenesis remains poorly understood. Recent studies have implicated microRNAs in iCCA progression. In this study, we demonstrated that miR-885-5p was significantly decreased in iCCA tissues. Downregulation of miR-885-5p was correlated with vascular invasion, lymph node metastasis, unfavorable overall survival, and shorter disease-free survival. Silencing or overexpressing miR-885-5p by lentiviral approaches significantly influenced iCCA cell proliferation and metastasis in vitro and in vivo. Mechanistically, overexpression of miR-885-5p inhibited iCCA metastasis and proliferation by directly inhibiting GALNT3 as well as by indirectly promoting the downregulation of insulin-like growth factor-2 mRNA-binding protein 1 (IGF2BP1). Furthermore, miR-885-5p inhibited iCCA metastasis by downregulating the PI3K/AKT/MMPs signaling pathway via targeting GALNT3. Collectively, we demonstrated that miR-885-5p was an important mediator of iCCA proliferation and metastasis by regulating GALNT3 and IGF2BP1, thus offering a potential target for iCCA treatment.

Abstract
This study set out to observe the value of miR-885-5p in the prognosis evaluation of liver cancer patients after transcatheter arterial chemoembolization. Sixty liver cancer patients treated in Zhuji City People's Hospital between January 2019 and September 2019 were enrolled. The patients were categorized into survival (SG) and death groups (DG) according to prognosis. Sixty-five healthy individuals were included as a control. The expression of miR-885-5p and miR-21were measured by the qRT-PCR and predictive value of diagnostic efficiency was determined by the ROC curve. Multivariate Cox regression analysis was performed to explore independent risk factors. Results showed that levels of miR-885-5p in the serum of liver cancer patients were obviously lower than that of the control group; however, levels of miR-21 in the serum of liver cancer patients were higher than that of healthy individuals. Patients with miR-885-5p low expression and miR-21 high expression had poor differentiation, stages III+IV, and their incidence of lymphatic invasion and distal metastasis was higher (P<0.05). AUC values of miR-885-5p and miR-21 single diagnosis were both > 0.8. The relative level of miR-885-5p in the serum of the SG was dramatically higher than that of the DG, and its relative level of miR-21 in serum was significantly decreased compared with DG. ROC curves in diagnosing the prognosis of liver cancer patients were drawn, AUC values of serum miR-885-5p and miR-21 in diagnosing their prognosis were both > 0.8. Cox regression analysis was carried out on independent factors affecting their prognosis. The results revealed that the TNM stage, lymphatic invasion, distal metastasis and miR-885-5p were independent prognostic factors affecting their 5-year survival. It was concluded that miR-885-5p exhibited the potential to be a serum biomarker to evaluate the efficacy of advanced liver cancer.

Abstract
Sunitinib is the most commonly used first-line therapy for the treatment of advanced renal cell carcinoma (RCC), but intrinsic and extrinsic resistance to targeted therapies dramatically compromise the benefit of clinical outcome. Dissecting the underlying mechanisms and discovering reliable predictive biomarkers are urgently needed in clinic. Here, we discovered miR-885-5p was notably decreased after sunitinib treatment and associated with poor disease progression in clear cell renal cell carcinoma (ccRCC). In vitro and in vivo studies identified miR-885-5p inhibition contributed to sunitinib resistance. Mechanistically, sunitinib treatment reduced GATA1 expression, which in turn reduced its binding to MIR885 promoter and resulted in miR-885-5p downregulation in transcriptional level. In addition, PLIN3 was confirmed to be directly targeted by miR-885-5p and its upregulation significantly increased lipid droplets formation to decrease sunitinib sensitivity. Therefore, GATA1/miR-885-5p/ PLIN3 pathway may serve as a potential therapeutic strategy and a biomarker for sunitinib treatment in ccRCC.

Abstract
Background Hepatocellular carcinoma (HCC) is the third major cause of cancer-related death. Mounting evidence shows that microRNAs play critical roles in the initiation and progression of HCC and may potentially serve as diagnostic markers for HCC. Methods and Results In the present study, we explored the biological effects of miR-885-5p on HCC progression. We performed flow cytometry analyses of miR-885-5p in HCC cell lines and identified miR-885-5p as a recurrence-related microRNA. Overexpression of miR-885-5p significantly inhibited cell migration, invasion, proliferation, angiogenesis and EMT. Then, the correlation of miR-885-5p and AEG1 were confirmed by using luciferase assays, quantitative real-time PCR analysis and Western blotting. It was subsequently confirmed that Astrocyte Elevated Gene1 (AEG1) was a direct target gene of miR-885-5p. Conclusion miR-885-5p likely acts as a tumor suppressor by regulating AEG1, suggesting that miR-885-5p may be a potential biomarker and can be targeted in therapeutic strategies against HCC in the future.

Abstract
The aim of the present study was to investigate the role of microRNA (miR)-885-5p in colorectal cancer cell proliferation and migration, and to determine the possible underlying molecular mechanisms. The expression of miR-885-5p in colorectal cancer tissue and cells was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The expression levels of three suppressor of cytokine signaling (SOCS) factors were detected by RT-qPCR and western blotting. The effects of miR-885-5p on tumor cell proliferation and migration were studied using MTT and Transwell assays, respectively. Additionally, the expression levels of epithelial-mesenchymal transition (EMT)-related proteins (N-cadherin, E-cadherin, vimentin and Snail) were detected by RT-qPCR and western blot analysis. Furthermore, the target of miR-885-5p was predicted and confirmed using a luciferase reporter assay. miR-885-5p was demonstrated to be upregulated and SOCS was downregulated in colorectal cancer tissue, and cells. miR-885-5p suppression significantly inhibited tumor cell proliferation and migration, promoted E-cadherin expression, and inhibited the expression levels of N-cadherin, vimentin and Snail. Further studies showed that SOCS5, SOCS6 and SOCS7 were direct targets of miR-885-5p. The results suggest that miR-885-5p suppression inhibited cell proliferation and migration, and the EMT process by targeting SOCS5, SOCS6 and SOCS7 genes in colorectal cancer. miR-885-5p and SOCS may be used for the diagnosis and treatment of colorectal cancer.

Abstract
Colorectal cancer is the third most common cancer in the world and liver is the most frequent site of distant metastasis with poor prognosis. The aim of this study is to investigate microRNAs leading to liver metastasis. We applied microarray analysis and quantitative PCR to identify and validate dysregulated miRNAs in liver metastases when compared to primary CRCs. Functional significance and the underlying molecular mechanism of selected miRNA was demonstrated by a series of in vitro and in vivo assays. Our microarray analysis and subsequent quantitative PCR validation revealed that miR-885-5p was strongly up-regulated in liver metastases and in CRC cell-lines derived from distant metastases. Overexpression of miR-885-5p significantly induced cell migration, cell invasion, formation of stress fibre in vitro and development of liver and lung metastases in vivo. MiR-885-5p induced metastatic potential of CRC by repressing cytoplasmic polyadenylation element binding protein 2 transcription through directly binding to two binding sites on its 3′ untranslated region, and consequently led to up-regulation of TWIST1 and hence epithelial-mesenchymal transition. Our findings demonstrated the overexpression of miR-885-5p in liver metastasis and its roles in inducing CRC metastasis, potentiating development of miR-885-5p inhibitor to treat advanced CRC in the future.

Abstract
MicroRNAs (miRNAs) inhibit or improve the malignant progression of hepatocellular carcinoma (HCC). We previously reported that compared to health controls, patients with liver cirrhosis present the highest levels of circulating miR-885-5p, followed by those with chronic hepatitis B and those with HCC. However, the molecular involvement of miR-885-5p in HCC metastasis is presently unclear. Here, we demonstrated that the expression of miR-885-5p negatively correlated with the invasive and metastatic capabilities of human HCC tissue samples and cell lines. We found that miR-885-5p expression levels correlated with the survival of patients with HCC. Overexpression of miR-885-5p decreased metastasis of HCC cells in vitro and in vivo. Inhibition of miR-885-5p improved proliferation of non-metastatic HCC cells. Furthermore, we disclosed that miR-885-5p targeted gene encoding β-catenin CTNNB1, leading to decreased activity of the Wnt/β-catenin signaling pathway. The present study indicates that miR-885-5p suppresses the metastasis of HCC and inhibits Wnt/β-catenin signaling pathway by its CTNNB1 target, which suggests that miR-885-5p to be a promising negative regulator of HCC progression and as a novel therapeutic agent to treat HCC.

Abstract
It is well established that ncRNAs are emerging as important regulators in various types of cancers, however, their functions and contributions in cancers remain insufficiently defined. In this study, we reported the expression levels of a long noncoding RNA (lncRNA), named HSP90AA1-IT1 (HSP90AA1 intronic transcript 1), appeared to correlate with the pathological grades of gliomas and high level of HSP90AA1-IT1 indicated poor prognosis. Downregulation of HSP90AA1-IT1 in the glioma cell lines significantly suppressed cell viability, proliferation, EMT, invasion and migration in addition to an increase in apoptosis and aberrant cell cycle progression. The tumorigenic capacity of these cells in vivo were also inhibited. We further demonstrated that the oncogenic effects of HSP90AA1-IT1 could be mediated by a direct binding to miR-885-5p. Sharing the same binding sites with CDK2, a key regulator in gliomagenesis, HSP90AA1-IT1 competitively bound to miR-885-5p, thereby prevented CDK2 from miR-885-5p mediated post-transcriptional repression. Taken together, it is concluded that HSP90AA1-IT1, performs its function via regulating the development of gliomas through miR-885-5p-CDK2 signaling axis, and this has added new perspective to its role in tumorigenesis, thus providing potential therapeutic targets for glioma treatment.

Abstract
OBJECTIVE To validate and to compare the circulating microRNA (miR) expression profiles between pre-eclampsia and healthy pregnant women, to perform correlation analysis of the differently expressed miRs with clinical and biochemical parameters, and to verify the extracellular localisation of miRs in apoptotic bodies, microvesicles, and exosomes. DESIGN A case-control study with a replication study. SETTING Pregnant women attending maternity hospitals in Southeastern Brazil. POPULATION Two obstetric white populations: a case-control study (19 pre-eclampsia and 14 healthy pregnant) and a replication study (eight pre-eclampsia and eight healthy pregnant). METHODS PCR-array with 84 different miRs was performed in plasma from five pre-eclampsia and four healthy pregnant women. In the case-control study, differently expressed miRs were validated using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR), and correlated with clinical and biochemical parameters. The plasma was then fractioned to study the extracellular localisation of miRs. MAIN OUTCOME MEASURES Gene expression profiles of miRs. RESULTS From PCR-array, three miRs (miR-376c-3p, miR-19a-3p, and miR-19b-3p) were found to be down-regulated and the miR-885-5p was found to be up-regulated in pre-eclampsia compared with healthy pregnant women. In the validation step, miR-885-5p was the only significantly different miR (fold-change = 5.0, P < 0.05), which was confirmed in the replication study (fold-change = 4.5, P < 0.05). Moreover, miR-885-5p was significantly correlated with the hepatic enzyme aspartate transaminase (r = 0.66; P = 0.0034) and it was mostly associated with the exosomes (32-fold higher than apoptotic bodies). CONCLUSIONS miR-885-5p is increased in plasma from pre-eclampsia compared with healthy pregnant women, and it is released into circulation mainly inside exosomes. TWEETABLE ABSTRACT: miR-885-5p is increased in pre-eclampsia and is released into circulation mainly inside exosomes.
