Abstract
Heat Shock Protein 90 (HSP90) is a potential drug target for cancer therapy as it is often dysregulated in several cancers, including lung, breast, pancreatic, and prostate cancers. In cancer, HSP90 fails to maintain the structural and functional integrity of its several client proteins which are involved in the hallmarks of cancer such as cell proliferation, invasion, migration, angiogenesis, and apoptosis. Several small molecule inhibitors of HSP90 have been shown to exhibit anticancer effects in vitro and in vivo animal models. However, a few of them are currently under clinical studies. The status and potential limitations of these inhibitors are discussed here. Studies demonstrate that several noncoding RNAs (ncRNAs) such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) regulate HSP90 and its client proteins to modulate cellular processes to exhibit oncogenic or tumor suppressing properties. Over the last decade, miRNAs and lncRNAs have drawn significant interest from the scientific community as therapeutic agents or targets for clinical applications. Here, we discuss the detailed mechanistic regulation of HSP90 and its client proteins by ncRNAs. Moreover, we highlight the significance of these ncRNAs as potential therapeutic agents/targets, and the challenges associated with ncRNA-based therapies. This article aims to provide a holistic view on HSP90-regulating ncRNAs for the development of novel therapeutic strategies to combat cancer.

Abstract
Retinoblastoma (RB) is a common cancer in infants and children. It is a curable disease; however, a delayed diagnosis or treatment makes the treatment difficult. Genetic mutations have a central role in the pathogenesis of RB. Genetic materials such as RNAs (coding and non-coding RNAs) are also involved in the progression of the tumor. Circular RNA (circRNA) is the most recently identified RNA and is involved in regulating gene expression mainly through "microRNA sponges". The dysregulation of circRNAs has been observed in several diseases and tumors. Also, various studies have shown that circRNAs expression is changed in RB tissues. Due to their role in the pathogenesis of the disease, circRNAs might be helpful as a diagnostic or prognostic biomarker in patients with RB. In addition, circRNAs could be a suitable therapeutic target to treat RB in a targeted therapy approach.

Abstract
Background Cervical cancer is the fourth most frequent malignancy among women globally, with approximately 604,000 new cases and 341,000 deaths per year. Necroptosis is a newly discovered mechanism of cell death involved in biological behaviors of cancer. Methods LASSO Cox regression analysis was conducted to construct a prognostic necroptosis-related signature. lncRNA–miRNA–mRNA regulatory axis was constructed with a ceRNA network. qRT-PCR was performed to verify our result. Results A total of 54 necroptosis-related genes were differentially expressed in cervical cancer (all p < 0.05). We also summarized genetic mutation landscape of necroptosis-related genes in cervical cancer. We then developed a necroptosis-related prognostic signature including 13 necroptosis-related genes (ATRX, AXL, DDX58, IDH1, ITPK1, MAP3K7, SLC39A7, TARDBP, TNF, TNFRSF1A, TNFRSF1B, TNFSF10, TRIM11) for cervical cancer. Cervical cancer patients with high riskscore had a poor overall survival (HR = 2.128, p = 0.00194) with an AUC of 0.725, 0.763 and 0.637 in 3-year, 5-year, and 10-year ROC curve. Consensus clustering analysis revealed that all cervical cancer cohort could be divided into three subtypes, which was correlated with different prognosis and immune infiltration (p < 0.05). A PPI network revealed TNF as the hub gene and TNF expression was correlated with immune infiltration (all p < 0.05), microsatellite instability (p < 0.012) and drug sensitivity (p < 0.05). The ceRNA network was performed and identified a lncRNA NUTM2B-AS1/miR-361-5p/TNF regulatory axis for cervical cancer. qRT-PCR result also suggested that TNF was upregulated in cervical cancer (p < 0.001) and associated with a poor overall survival (p = 0.007). Univariate and multivariate analysis demonstrated TNF expression, lymph node metastasis and clinical stage were prognosis factors of cervical cancer patients (p < 0.05). Conclusion We developed a necroptosis-related prognostic signature including 13 necroptosis-related genes for cervical cancer. Moreover, we also identified a lncRNA NUTM2B-AS1/miR-361-5p/TNF regulatory axis, which may play a vital role in the progression of cervical cancer. Further studies should be conducted to verify these results.

Abstract
Cervical cancer (CC) is a type of gynecological malignancy that poses a significant threat to females. The aim of the present study was to examine the role of long intergenic non-protein coding RNA 1123 (LINC01123) and its underlying molecular mechanism in the development of CC. mRNA expression levels of LINC01123 and microRNA (miR)-361-3p in CC tissue samples and cell lines were evaluated using reverse transcription-quantitative PCR. Cell viability, migration and invasion were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, wound healing and Transwell assays. Moreover, a xenograft tumor model was established for elucidating the influence of LINC01123 knockdown on tumor growth in vivo. A dual-luciferase reporter assay was used to confirm the association between LINC01123 and miR-361-3p, and miR-361-3p and tetraspanin 1 (TSPAN1). Western blot analysis was used to determine TSPAN1 protein expression. LINC01123 expression was upregulated and miR-361-3p expression was reduced in CC tissue samples and cell lines. Knockdown of LINC01123 inhibited cell viability, migration and invasion in vitro, and suppressed tumor growth in vivo. Furthermore, LINC01123 targeted miR-361-3p and negatively regulated miR-361-3p expression. Overexpression of miR-361-3p inhibited cell viability, migration and invasion in HeLa and CaSki cells. Additionally, miR-361-3p targeted TSPAN1 and negatively regulated TSPAN1 expression. Inhibition of miR-361-3p and overexpression of TSPAN1 reversed the effect of LINC01123 knockdown on cell proliferation, migration and invasion in HeLa cells. Knockdown of LINC01123 inhibited cell proliferation, migration and invasion via miR-361-3p/TSPAN1 regulation in CC, which may present an effective target for treatment of CC.

Abstract
Reduced inflammation, increased insulin sensitivity, and protection against cancer are shared between humans and mice with GH/IGF1 deficiency. Beyond hormone levels, miRNAs are important regulators of metabolic changes associated with healthy aging. We hypothesized that GH deficiency in humans alters the abundance of circulating miRNAs and that a subset of those miRNAs may overlap with those found in GH-deficient mice. In this study, subjects with untreated congenital isolated GH deficiency (IGHD; n = 23) and control subjects matched by age and sex (n = 23) were recruited and serum was collected for miRNA sequencing. Serum miRNAs from young (6 month) and old (22 month) Ames dwarf (df/df) mice with GH deficiency and their WT littermates (n = 5/age/genotype group) were used for comparison. We observed 14 miRNAs regulated with a genotype by age effect and 19 miRNAs regulated with a genotype effect independent of age in serum of IGHD subjects. These regulated miRNAs are known for targeting pathways associated with longevity such as mTOR, insulin signaling, and FoxO. The aging function was overrepresented in IGHD individuals, mediated by hsa-miR-31, hsa-miR-146b, hsa-miR-30e, hsa-miR-100, hsa-miR-181b-2, hsa-miR-195, and hsa-miR-181b-1, which target the FoxO and mTOR pathways. Intriguingly, miR-181b-5p, miR-361-3p, miR-144-3p, and miR-155-5p were commonly regulated in the serum of humans and GH-deficient mice. In vitro assays confirmed target genes for the main up-regulated miRNAs, suggesting miRNAs regulated in IGHD individuals can regulate the expression of age-related genes. These findings indicate that systemic miRNAs regulated in IGHD individuals target pathways involved in aging in both humans and mice.

Abstract
Aim: There is growing evidence for the possible use of microRNAs (miRNAs) in cancers as diagnostic as well as prognostic biomarkers in the present era of Personalized Medicine. The objective of the present systematic review and meta-analysis was to assess the prognostic role of microRNAs in uterine cervical cancers. Methods: A systematic review and meta-analysis was carried out searching electronic databases for published articles between January 2009 and August 2020 based on standard systematic review guidelines. Meta-analysis was performed by pooling the hazard ratio (HR) with 95% confidence interval (CI) to assess the prognostic value of deregulated miRNAs by the random-effects model. Results: In the present meta-analysis, the aberrant expression of 14 microRNAs in 1,526 uterine cervical cancer cases before definitive therapy from 14 case-control studies were assessed. The pooled HR of two miRNAs, miRNA-155 and miRNA-224 which were upregulated in cervical cancer tissues was 1.76 (95% CI 1.27-2.45) revealing significant association with overall poor survival. Meanwhile, the pooled HR was 1.53 (95% CI 0.94-2.94) when all the deregulated miRNAs in cervical cancer tissues were evaluated. The pooled HR of downregulated miRNAs was 1.46 (95% CI 0.81, 2.64). Meanwhile, the pooled HR of three upregulated miRNAs-425-5p, 196a, 205 in the serum sample was 1.37 (95% CI 0.45 -4.20). Conclusion: The downregulation of aberrant miRNAs was not associated with poor overall survival rates.

Hypoxic colorectal cancer-derived extracellular vesicles deliver microRNA-361-3p to facilitate cell proliferation by targeting TRAF3 via the noncanonical NF-κB pathways. Clin Transl Med 2021; 11:e349.

Abstract
BACKGROUND Hypoxic tumour microenvironment (TME) is a key regulator in cancer progression. However, the communications between hypoxic cells and other components in TME during colorectal cancer (CRC) progression via extracellular vesicles (EVs) remain unclear. METHODS High-throughput sequencing was employed to detect aberrantly expressed microRNAs (miRNAs) in hypoxic EVs. Quantitative real-time PCR was used to confirm and screen preliminarily candidate miRNAs. The effects of EVs derived from hypoxia (<1% O2 ) and miR-361-3p on CRC growth were assessed using CCK-8 assays, colony formation assays, EdU assays, flow cytometric assays and mouse xenograft. Then, the specific mechanisms of miR-361-3p were investigated by RNA immunoprecipitation, luciferase reporter assay, Western blot, chromatin immunoprecipitation, immunohistochemistry and rescue experiments. RESULTS The level of miR-361-3p expression was remarkably elevated in hypoxic EVs and can be transferred to CRC cells. Functional experiments exhibited that hypoxic EVs facilitated cell growth and suppressed cell apoptosis by transferring miR-361-3p of CRC. Hypoxia-inducible factor-1α induced the elevation of miR-361-3p levels in hypoxic EVs. Upregulated miR-361-3p in CRC inhibited cell apoptosis and facilitated cell growth by directly targeting TNF receptor-associated factor 3, which consequently activated the noncanonical NF-κB pathway. Moreover, the high expression of circulating exosomal miR-361-3p was correlated to worse prognosis of CRC patients. CONCLUSIONS Altogether, the abnormality of exosomal miR-361-3p derived from hypoxia acts vital roles in the regulation of CRC growth and apoptosis and can be an emerging prognostic biomarker and a therapeutic target for CRC patients.

Abstract
Background MicroRNA is involved in the development of lymphoma. It is reported that miR-361-3p has a tumor inhibitory effect, but its role in lymphoma is still unclear. The purpose of this study is to examine whether miR-361-3p can inhibit the development of lymphoma and further explore the related potential mechanism. Methods In this study, we first analyzed the biological function of miR-361-3p in transfected Raji that mimicked miRNA. We also analyzed the biological function of the whole population in stably expressed miR-361-3p transgenic cells. Next, we conducted a complete micro-gene network to test the genetic profile of differential expression of stable gene-modified cells. Results We found that miR-361-3p expression was often reduced in lymphoma cell lines. Cellular assays have shown a significant role in inhibiting the growth of miR-361-3p by inhibiting lymphoma proliferation and migration, and severely inhibiting the Wnt/β-catenin series protein signal. Bioinformatics analysis shows that Wnt10A is a new target of miR-361-3p, which is confirmed by our mechanism research. It is confirmed that restoring Wnt10A can reduce the tumor inhibition of Wnt/β-catenin during lymphoma progression and restore the normal signal of Wnt/β-catenin series proteins. Discussion Our data indicate that miR-361-3p inhibits the Wnt/β-catenin protein signal by locking Wnt10A, which is an important factor in inhibiting the tumor in the pathogenesis of lymphoma. The miR-361-3p/Wnt10A axis may be a promising target for the treatment of lymphoma.

Abstract
Recent studies have suggested that Hippo signaling is not only involved in controlling organ size in Drosophila but can also regulate cell proliferation, tissue homeostasis, differentiation, apoptosis and regeneration. Any dysregulation of Hippo signaling, especially the hyper activation of its downstream effectors YAP/TAZ, can lead to uncontrolled cell proliferation and malignant transformation. In majority of cancers, expression of YAP/TAZ is extremely high and this increased expression of YAP/TAZ has been shown to be an independent predictor of prognosis and indicator of increased cell proliferation, metastasis and poor survival. In this review, we have summarized the most recent findings about the cross talk of Hippo signaling pathway with other signaling pathways and its regulation by different miRNAs in various cancer types. Recent evidence has suggested that Hippo pathway is also involved in mediating the resistance of different cancer cells to chemotherapeutic drugs and in a few cancer types, this is brought about by regulating miRNAs. Therefore, the delineation of the underlying mechanisms regulating the chemotherapeutic resistance might help in developing better treatment options. This review has attempted to provide an overview of different drugs/options which can be utilized to target oncogenic YAP/TAZ proteins for therapeutic interventions.

Abstract
Mounting evidence indicates that the long non-coding RNA (lncRNA) LINC00460 plays an oncogenic role in tumor progression; however, the role of LINC00460 in cervical cancer (CC) remains unknown. In this study, we found that LINC00460 was frequently upregulated in CC tissues and cell lines. Knockdown of LINC00460 repressed CC cell growth and invasion in vitro and attenuated tumorigenesis in vivo. Mechanistically, miR-361-3p was predicted as a direct target of LINC00460 by bioinformatics analysis, which was further confirmed by qRT-PCR, dual-luciferase reporter assays, and rescue experiments. Furthermore, miR-361-3p targeted the 3' untranslated region (UTR) of Gli1 mRNA and repressed its expression. Taken together, our study revealed that LINC00460 functions as an oncogenic lncRNA in CC, indicating the likely participation of the LINC00460/miR-361-3p/Gli1 pathway in the disease. Accordingly, our results provide new insight into CC tumorigenesis.

Abstract
Background Increasing researches have reported that circular RNA UBAP2 (circUBAP2) may be a potential prognosis biomarker and participate in the development of several cancers; however, the role of circUBAP2 in cervical cancer (CC) remains largely unclear. Methods We applied qRT-PCR and Western blot to examine expression levels of circUBAP2, miR-361-3p, SOX4, Bax, Bcl-2, Cleaved caspase 3, N-cadherin, Vimentin and E-cadherin. Cell proliferation, apoptosis, invasion and migration were analyzed by MTT assay, Flow cytometry, and Transwell assay, respectively. The interaction between miR-361-3p and circUBAP2 or SOX4 was confirmed by luciferase reporter assay and pull-down assay. Murine xenograft model was established by injecting SiHa cells which stably transfected sh-circUBAP2. Results CircUBAP2 was up-regulated in CC tissues and cell lines and high circUBAP2 expression predicated poor outcome. Knockdown of circUBAP2 suppressed cell proliferation, migration, invasion and EMT, while induced apoptosis in CC in vitro, and inhibited tumor growth and metastasis in vivo. MiR-361-3p directly bound to circUBAP2 or SOX4, and circUBAP2 could regulate SOX4 expression by sponging miR-361-3p in CC cells. Furthermore, rescue assay results demonstrated that the inhibitory effects of circUBAP2 knockdown on cell growth and metastasis were partially reversed by miR-361-3p down-regulation or SOX4 up-regulation in CC. Conclusion CircUBAP2 represents a prognostic marker and contributes to tumor growth and metastasis via modulating miR-361-3p/SOX4 axis in CC, which indicates a potential therapeutic target for CC treatment.

Abstract
Analysis of the microRNA (miRNA) expression signature of breast cancer based on RNA sequencing demonstrated that miR-361-3p was significantly upregulated in breast cancer tissues. miR-361-3p is a novel miRNA, and its role in breast cancer is currently unclear. The aim of the present study was to investigate the functions of miR-361-3p in breast carcinoma. In this study, it was observed that the expression of miR-361-3p in cancer tissues was significantly higher compared with that in para-cancerous tissues and was correlated with advanced TNM stage, Ki-67 overexpression and shorter disease-free survival. Overexpression of miR-361-3p promoted proliferation and inhibited apoptosis of breast cancer cells. Through RNA sequencing, multi-library retrieval, luciferase reporter assays, quantitative polymerase chain reaction analysis, western blotting and other methods, it was verified that E2F1 was directly downregulated by miR-361-3p. The knockdown of E2F1 by siRNA promoted breast cancer cell proliferation and inhibited apoptosis, similar to miR-361-3p. In addition, miR-361-3p was able to decrease the expression of P73 by targeting E2F1, whereas overexpression of P73 reversed the effect of miR-361-3p on the viability of breast cancer cell lines. Thus, the present study demonstrated that miR-361-3p acts as an oncomiR in breast cancer to promote proliferation and inhibit apoptosis through inhibiting the P73 pathway by downregulating E2F1 expression, which may uncover valuable prognostic factors or treatment targets.

Abstract
Although the cases of endometrial carcinoma (EC) is gradually increasing across the world, its etiology and pathogenesis remain unknown. The present study is the first to define the role and biological function of circRNA hsa_circ_0075960 in the development and progression of EC. We first determined that hsa_circ_0075960 is aberrantly expressed in EC cells. Then, we uncovered that the downregulation of hsa_circ_0075960 suppressed cell proliferation and promoted cell apoptosis of EC cells, suggesting that hsa_circ_0075960 could inhibit the progression of EC in vitro. In addition, we identified that miR-361-3p was the direct target of hsa_circ_0075960. Further analysis revealed that hsa_circ_0075960 affected the development of EC via sponging miR-361-3p. Interestingly, we verified that the level of SH2B1 was controlled by the downregulation of hsa_circ_0075960 and that the negative effect caused by hsa_circ_0075960 could be reversed via miR-361-3p inhibition. Our cumulative results revealed that the novel tumor regulator hsa_circ_0075960 functioned as a sponge for miR-361-3p/SH2B1 in EC cells and regulated the progression of EC through the modulation of miR-361-3p.

Abstract
Background Circular RNAs (circRNAs) have been considered as a key regulator in tumor carcinogenesis. However, the roles and underlying mechanisms of circRNAs in cervical cancer (CC) remain largely unknown. In this study, we explored the effects of circ-MYBL2 (hsa_circ_0060467) on CC progression. Methods Levels of circ-MYBL2 and miR-361-3p were examined by qRT-PCR. CCK-8 assay, colony formation assay and transwell invasion assay were used to determine the roles of circ-MYBL2 in CC. Dual-luciferase reporter and RNA pull down assays were employed to verify the relationship between circ-MYBL2 and miR-361-3p. Results We showed that the expression of circ-MYBL2 was significantly upregulated and positively associated with advanced FIGO stage, larger tumor size, lymph node metastasis, and poor prognosis in CC patients. Function assays revealed that circ-MYBL2 inhibition suppressed CC cells’ proliferation, invasion and epithelial–mesenchymal transition (EMT) processes. In mechanism, miR-361-3p was identified as a direct target of circ-MYBL2, rescue assays showed that miR-361-3p suppression reversed the effects of si-circ-MYBL2 on CC cells’ progression. Conclusion Our findings suggested that circ-MYBL2 promoted CC progression by regulating miR-361-3p expression, which provided a novel therapeutic target for the treatment of CC patients.

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) has a relatively improved remission rate, but the poor outcomes are primarily due to resistance and relapse. Moreover, organs infiltration trends to occur during remission. Rapamycin was applied to treat malignancies for decades. In this investigation, we aimed to explore the molecular mechanisms and pathway changes during the T-ALL therapeutic process. T-ALL cell line Molt-4 cells were treated with rapamycin and performed microarray analysis to identify the deregulated miRNAs and mRNAs (log2 fold change>2 or <-2). To obtain regulatory miRNA/mRNA network, miRNA target prediction softwares and Cytoscape were used to plot and modularize the rapamycin treatment-related network. Surprisingly, the enriched pathways were not involved in mediating either cell death or apoptosis but were responsible for angiogenesis, cell survival, and anti-apoptosis, which is consistent with the Gene Ontology analysis and PPI network based on all deregulated mRNAs, indicating that these elements likely play a role in promoting Molt-4 cell survival or escaping from rapamycin. The expression of 3 miRNAs (miR-149-3p, miR-361-3p, and miR-944) and their putative targets, which play central roles in their module, were validated by qRT-PCR. These results provide novel insight into potentially relevant biological pathways for T-ALL cells escaping from chemotherapy or developing central nervous system infiltration.

[PMID: 31082771 DOI: 10.1016/j.biopha.2019.108944] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Revised: 04/16/2019] [Accepted: 04/29/2019] [Indexed: 10/26/2022] Open
Abstract
The current study was undertaken to investigate the potential influence of methylation on miR-362-5p/3p expression and further analyzed their independent prognostic value in cervical adenocarcinoma (ADC) and squamous cell carcinoma (SCC) respectively. SiHa and CaSki cells were used as the in vitro cell model. In silico bioinformatic analysis was conducted via the combined use of the Cancer Genome Atlas-Cervical Cancer (TCGA-CESC), Starbase 3.0 and String 10.5. Results revealed that the downregulation of miR-362-5p/3p was accompanied by the infection of high-risk human papillomavirus (HR-HPV) and their expression was further decreased in HR-HPV cancer tissues. Demethylation could restore their expression. By performing Methylation-specific PCR (MSP) based on methylated or unmethylated specific primers, we confirmed that the proximal promoter region was methylated in both cell lines. Higher miR-362-3p expression might independently predict favorable overall survival (OS) in SCC patients (HR: 0.561, 95%CI: 0.354-0.889, p = 0.014), after adjustment of clinical stages, lymphovascular invasion and miR-362-5p expression. However, no prognostic value of miR-362-5p or miR-362-3p expression was observed in terms of OS in patients with ADC. Via bioinformatic analysis, we found that miR-362-3p might have an entirely different regulatory network in cervical ADC and SCC, which might help to explain the distinct prognostic value of miR-362-3p in these two histological subtypes. In summary, we infer that the methylation level of the proximal promoter region of pre-miR-362 would influence the expression of miR-362-5p/3p in cervical cancer. MiR-362-3p expression might be a specific prognostic biomarker in cervical SCC, but not in ADC.
