Abstract
The major challenges in Osteosarcoma (OS) therapy are its heterogeneity and drug resistance. The development of new therapeutic approaches to overcome the major growth mechanisms of OS is urgently needed. The search for specific molecular targets and promising innovative approaches in OS therapy, including drug delivery methods, is an urgent problem. Modern regenerative medicine focuses on harnessing the potential of mesenchymal stem cells (MSCs) because they have low immunogenicity. MSCs are important cells that have received considerable attention in cancer research. Currently, new cell-based methods for using MSCs in medicine are being actively investigated and tested, especially as carriers for chemotherapeutics, nanoparticles, and photosensitizers. However, despite the inexhaustible regenerative potential and known anticancer properties of MSCs, they may trigger the development and progression of bone tumors. A better understanding of the complex cellular and molecular mechanisms of OS pathogenesis is essential to identify novel molecular effectors involved in oncogenesis. The current review focuses on signaling pathways and miRNAs involved in the development of OS and describes the role of MSCs in oncogenesis and their potential for antitumor cell-based therapy.

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
Rho Associated Coiled-Coil Containing Protein Kinase 1 (ROCK1) is a protein serine/threonine kinase which is activated upon binding with the GTP-bound form of Rho. This protein can modulate actin-myosin contraction and stability. Moreover, it has a crucial role in the regulation of cell polarity. Therefore, it participates in modulation of cell morphology, regulation of expression of genes, cell proliferation and differentiation, apoptotic processes as well as oncogenic processes. Recent studies have highlighted interactions between ROCK1 and several non-coding RNAs, namely microRNAs, circular RNAs and long non-coding RNAs. Such interactions can be a target of medications. In fact, it seems that the interactions are implicated in therapeutic response to several medications. In the current review, we aimed to explain the impact of these interactions in the pathoetiology of cancers as well as non-malignant disorders.

EXPERIMENTAL & MOLECULAR MEDICINE 2022; 54:1024-1037. [PMID: 35879346 PMCID: PMC9356001 DOI: 10.1038/s12276-022-00806-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 03/15/2022] [Accepted: 04/26/2022] [Indexed: 12/20/2022]
Abstract
As the most prevalent bone tumor in children and adolescents, the pathogenesis and metastasis of osteosarcoma (OS) remain largely unclear. Here, we investigated the expression and function of a novel circular RNA (circRNA), circROCK1-E3/E4, which is back-spliced from exons 3 and 4 of Rho-associated coiled-coil containing protein kinase 1 (ROCK1) in OS. We found that circROCK1-E3/E4, regulated by the well-known RNA-binding protein quaking (QKI), was downregulated in OS and correlated with unfavorable clinical features of patients with OS. Functional proliferation and cell motility assays indicated that circROCK1-E3/E4 serves as a tumor suppressor in OS cells. Mechanistically, circROCK1-E3/E4 suppressed proliferation and migration by upregulating phosphatase and tensin homolog (PTEN) through microRNA-532-5p (miR-532-5p) sponging. In the constructed nude mouse model, circROCK1-E3/E4 inhibited tumor growth and lung metastasis in vivo. This study demonstrates the functions and molecular mechanisms of circROCK1-E3/E4 in the progression of OS. These findings may identify novel targets for the molecular therapy of OS. Understanding the role of a circular RNA molecule in bone cancer may provide a foundation for potential therapies. The factors underlying the development and progression of osteosarcoma, an aggressive bone cancer most common in young people, remain unclear. Circular RNAs (circRNAs), derived from RNA splicing events, have multiple functions in diseases such as cancer. Yong Wang at Zhejiang University, China, and co-workers had already demonstrated that the ROCK1 gene plays critical roles in osteosarcoma progression. Now, they have identified a novel circRNA called circROCK1-E3/E4 derived from ROCK1, which acts as a tumor suppressor in osteosarcoma. In experiments on human cell lines and mouse models, they found that circROCK1-E3/E4 regulates a key pathway that suppresses the proliferation and migration of cancer cells. Poor prognosis is linked to downregulated levels of this circRNA.

Abstract
Osteosarcoma (OS) is the common bone tumor in children and adolescents. Because of chemotherapy resistance, the OS patients have a poor prognosis. The one reason of chemotherapeutic resistance is the development of cancer stem cells (CSCs). CSCs represent a small portion of tumor cells with the capacity of self-renewal and multipotency, which are associated with tumor initiation, metastasis, recurrence and drug resistance. Recently, noncoding RNAs (ncRNAs) have been reported to critically regulate CSCs. Therefore, in this review article, we described the role of ncRNAs, especially miRNAs, lncRNAs and circRNAs, in regulating CSCs development and potential mechanisms. Specifically, we discussed the role of multiple miRNAs in targeting CSCs, including miR-26a, miR-29b, miR-34a, miR-133a, miR-143, miR-335, miR-382, miR-499a, miR-1247, and let-7days. Moreover, we highlighted the functions of lncRNAs in regulating CSCs in OS, such as B4GALT1-AS1, DANCR, DLX6-AS1, FER1L4, HIF2PUT, LINK-A, MALAT1, SOX2-OT, and THOR. Due to the critical roles of ncRNAs in regulation of OS CSCs, targeting ncRNAs might be a novel strategy for eliminating CSCs for OS therapy.

Abstract
BACKGROUND Circular RNA (circRNA) plays an important role in the malignant progression of many tumors, including retinoblastoma (RB). However, the role and regulatory mechanism of circ-E2F3 in RB have not been fully elucidated. METHODS Quantitative real-time PCR was used to measure circ-E2F3, miR-204-5p and Rho-associated protein kinase 1 (ROCK1) expression. Cell proliferation, apoptosis and metastasis were monitored by MTT, colony formation, flow cytometry, transwell and wound healing assays. Dual-luciferase reporter assay was employed to verify the relationship between miR-204-5p and circ-E2F3 or ROCK1. ROCK1 protein expression was detected by western blot assay. Mice xenograft models were built to assess the role of circ-E2F3 on RB tumor growth. RESULTS Circ-E2F3 was upregulated in RB tissues and cells. Silencing of circ-E2F3 inhibited the proliferation, migration, invasion, and induced the apoptosis of RB cells in vitro, as well as reduced RB tumor growth in vivo. MiR-204-5p could be sponged by circ-E2F3, and its inhibitor reversed the suppressive effect of circ-E2F3 silencing on RB progression. In addition, ROCK1 was confirmed to interact with miR-204-5p. MiR-204-5p regulated RB progression by targeting ROCK1. Also, circ-E2F3 positively regulated ROCK1 expression by sponging miR-204-5p. CONCLUSION Circ-E2F3 functioned as a tumor promoter in RB through the miR-204-5p/ROCK1 axis.

Abstract
Non‐coding RNAs are closely associated with tumorigenesis in multiple malignant tumours, including osteosarcoma (OS). Long non‐coding RNA Ewing sarcoma‐associated transcript 1 (EWSAT1) plays a role in metastasis, and actin cytoskeletal changes in OS remain unclear. In the current study, we showed that EWSAT1 expression was up‐regulated in OS and that an elevation in the EWSAT1 expression level was correlated with poor prognosis in patients with OS. Functionally, we showed that knockdown of EWSAT1 suppressed migration and induced actin stress fibre degradation in MNNG/HOS and 143B cells. Moreover, we found that ROCK1 was a key downstream effector in EWSAT1‐mediated cell migration and actin stress fibre changes. Furthermore, we demonstrated that ROCK1 and EWSAT1 shared a similar microRNA response element of microRNA‐24‐3p (miR‐24‐3p). Moreover, we verified that miR‐24‐3p suppressed ROCK1 and its mediated migration and actin stress fibres change by direct targeting. EWSAT1 promoted ROCK1‐mediated migration and actin stress fibre formation through miR‐24‐3p sponging. Lastly, through an in vivo study, we demonstrated that EWSAT1 promoted lung metastasis in OS. According to the above‐mentioned results, we suggest that EWSAT1 acts as an oncogene and that EWSAT1/miR‐24‐3p/ROCK1 axial could be a new target in the treatment of OS.

Abstract
OBJECTIVE Many studies have already suggested the role of long non-coding RNAs (lncRNAs) in Alzheimer's disease (AD), but the functions of lncRNA Taurine Upregulated Gene 1 (TUG1) in AD have been scarcely discussed. This study aims to verify how TUG1 affects hippocampal neurons in AD through modulation of microRNA-15a (miR-15a)/Rho-associated protein kinase 1 (ROCK1). METHOD AD mice was modeled through injection of β-amyloid 25-35 (Aβ25-35) into the lateral ventricle. After modeling, the mice were injected with altered TUG1 and/or miR-15a agomir lentiviruses. The spatial learning ability and memory ability of mice were detected through Morris water maze test. Hippocampal neuronal apoptosis and oxidative stress indicators in AD mice were then detected. The hippocampal neuron AD model was induced by Aβ25-35. Next, the neurons were, respectively, transfected with altered TUG1 vector and/or miR-15a mimics to determine the proliferation inhibition and apoptosis of hippocampal neurons. The interactions between TUG1 and miR-15a, and between miR-15a and ROCK1 were assessed using bioinformatic prediction, dual luciferase reporter gene assay and RNA-pull-down assay. RESULTS In the animal models, Aβ25-35-induced mice exhibited decreased spatial learning and memory ability, obvious pathological injury, promoted hippocampal neuronal apoptosis and decreased antioxidant ability. TUG1 silencing and miR-15a elevation improved spatial learning ability and memory ability, ameliorated pathological injury, depressed neuronal apoptosis, and strengthened antioxidant ability of hippocampal neurons in AD mice. In cellular models, Aβ25-35-treated hippocampal neurons presented inhibited neuronal viability and promoted neuronal apoptosis. TUG1 silencing and miR-15a elevation increased viability and limited apoptosis of Aβ25-35-treated hippocampal neurons. TUG1 specifically bound to miR-15a, and miR-15a targeted ROCK1. CONCLUSION Collectively, this study reveals that TUG1 knockdown restricts apoptosis of hippocampal neurons in AD by elevating miR-15a and suppressing ROCK1 expression, and provides a new therapeutic target for AD treatment.

Abstract
BACKGROUND Propofol is an intravenous drug commonly used in anesthesia procedures and intensive care in children. However, it also has neurotoxic effects on children. MicroRNA plays an important role in neurological diseases and neurotoxicity. METHODS In this study, primary rat hippocampal neurons were used to investigate the role of miR- 582-5p in propofol-induced neurotoxicity. Cell viability was monitored by 3-(4,5-dimethylthiazolyl)- 2,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, while the expression of proteins was monitored by real-time quantitation polymerase chain reaction (RT-qPCR) and western blot. TargetScan and double luciferase report assay were used to predict the targeting relationship between miR-582-5p and Rho-associated serine-threonine protein kinase 1 (ROCK1). RESULTS In the present study, the viability of neurons and the expression of miR-582-5p were decreased in a time-dependent manner after propofol treatment. Besides, miR-582-5p overexpression significantly reduced the toxicity of propofol on neuron cells but had no significant effect on normal nerve cells. In addition, miR-582-5p overexpression significantly reversed the expression of apoptosis-related proteins (cleaved caspase 3 and cleaved caspase 9) induced by propofol but had no significant effect in normal nerve cells. TargetScan and Dual-luciferase report assay revealed that ROCK1 was a targeted regulatory gene for miR-582-5p, and propofol treatment up-regulated ROCK1 expression by inhibiting miR-582-5p expression. Notably, miR-582-5p overexpression significantly increased cell viability, while ROCK1 overexpression reversed the effect of miR-582- 5p. CONCLUSION Taken together, these findings suggest that miR-582-5p alleviated propofol-induced apoptosis of newborn rat neurons by inhibiting ROCK1.

Abstract
A Rho-associated coiled-coil kinase (ROCK) is identified as a critical downstream effector of GTPase RhoA which contains two isoforms, ROCK1 (also known as p160ROCK and ROKβ) and ROCK2 (also known as Rho-kinase and ROKα), the gene of which is placed on chromosomes 18 (18q11.1) and 2 (2p24), respectively. ROCKs have a principal function in the generation of actin-myosin contractility and regulation of actin cytoskeleton dynamics. They represent a chief role in regulating various cellular functions, such as apoptosis, growth, migration, and metabolism through modulation of cytoskeletal actin synthesis, and cellular contraction through phosphorylation of numerous downstream targets. Emerging evidence has indicated that ROCKs present a significant function in cardiac physiology. Of note, dysregulation of ROCKs involves in several cardiac pathological processes like cardiac hypertrophy, cardiac fibrosis, systemic blood pressure disorder, and pulmonary hypertension. Moreover, ROCKs, in addition to their role in regulating renal arteriolar contraction, glomerular blood flow, and filtration, can also play a role in controlling podocytes, tubular cells, and mesangial cell structure and function. Hyperactivity disorder and over-gene expression of Rho/ROCK have been indicated in different cancers. Furthermore, it seems that increasing the expression of mRNA or ROCK protein has an undesirable effect on patient survival and has a positive impact on the progression and worsening of disease prognosis. This review focuses on the physiological and pathological functions of ROCKs with a particular view on its possible value of ROCK inhibitors as a new therapy in cancers and non-cancer diseases.

Abstract
Progresses in multimodal treatments have significantly improved the outcomes for childhood cancer. Nonetheless, for about one-third of patients with Ewing sarcoma, rhabdomyosarcoma, or osteosarcoma steady remission has remained intangible. Thus, new biomarkers to improve early diagnosis and the development of precision-targeted medicine remain imperative. Over the last decade, remarkable progress has been made in the basic understanding of miRNAs function and in interpreting the contribution of their dysregulation to cancer development and progression. On this basis, this review focuses on what has been learned about the pivotal roles of miRNAs in the regulation of key genes implicated in childhood sarcomas.

Abstract
BACKGROUND To explore the expression level of miR-664-3p in osteosarcoma and its effects on the proliferation and apoptosis of osteosarcoma cells. METHODS Specimens of osteosarcoma tissues were collected from 41 cases undergoing surgical treatment in the Orthopedics Department of Wuhan Puai Hospital, Wuhan, China from January 2015 to February 2018. Another 40 cases of normal bone tissue were collected. The expression of miR-664-3p were detected using quantificational real-time polymerase chain reaction. miR-664-3p mimics, miR-664-3p inhibitor and miR-664-3p negative control (NC) were used to transfect U2-OS, which were named as mimics group, inhibitor group and NC group, respectively. MTT assay was adopted to detect the effects of microRNA-664-3p on the proliferation of U2-OS after 24, 48, 72, 96 and 120 hours of transfection. Flow cytometry was applied to measure the apoptosis rate of U2-OS after miR-664-3p transfection. Finally, Western Blot was employed to detect the expression of proteolipid protein 2 (PLP2). RESULTS The total apoptosis rate of cells in the inhibitor group was obviously higher than those in the mimics group and the NC group (P<0.001). The relative expression level of PLP2 in the inhibitor group was significantly lower than those in the mimics group and the NC group (P<0.001). CONCLUSION MiR-664-3p may be involved in the occurrence and development of osteosarcoma, and can regulate the proliferation and apoptosis of U2-OS cells, and the expression of PLP2. Besides, miR-664-3p may become a novel molecular biological indicator for the diagnosis, targeted treatment and prognosis assessment of osteosarcoma.

Abstract
Lung cancer is regarded as one of the dominant causes in cancer patients among men and women all over the world. Rho-associated coiled-coil forming protein kinase l (ROCK1) is characterized as pivotal downstream effectors of the small GTPase RhoA and reported to participate in tumor metastasis. miR-335-5p acts as tumor suppressor microRNA and is identified to be downregulated in tumor tissues. miR-335-5p/ROCK1 axis has been demonstrated to promote cell proliferation and metastasis in gastric cancer, hepatocellular carcinoma and so on. However, the role it plays in promoting cell proliferation in non-small cell lung cancer (NSCLC) is poorly understood. Here, we demonstrated that the upregulated expression of ROCK1 was highly correlated with downregulated expression of miR-335-5p in NSCLC tissues and cell lines. Mechanistically, Knockdown of ROCK1 inhibited cell proliferation in vitro, accompanied by cell cycle change confirmed by flow analysis. Furthermore, miR-335-5p can downregulate the ROCK1 expression by directly binding to the 3'-untranslated region in posttranscriptional level. In vivo animal model showed similar results. Our findings highlighted the crucial role that miR-335-5p acted as a tumor suppressor to modulate cell proliferation and cell cycle progression via downregulating ROCK1 expression. And this miR-335-5p/ROCK1 axis contributed to NSCLC pathogenesis and might be promising targets for NSCLC therapy.

Abstract
Long non-coding (lnc)RNA heart and neural crest derivatives expressed 2-antisense RNA 1 (HAND2-AS1), an lncRNA antisense transcript adjacent to the heart and neural crest derivatives expressed 2 protein (HAND2), inhibits the development of several types of cancer; however, its role in melanoma is currently unknown. In the present study, it was revealed that lncRNA HAND2-AS1 was downregulated, whereas Rho-associated protein kinase 1 (ROCK1) mRNA was upregulated in tumor tissues when compared with the healthy tissues of patients with melanoma. Expression levels of lncRNA HAND2-AS1 and ROCK1 were inversely correlated in tumor tissues, but not in healthy tissues. LncRNA HAND2-AS1 expression levels were affected by tumor thickness, but not by tumor metastasis. LncRNA HAND2-AS1 overexpression led to inhibited melanoma cancer cell proliferation and an increased expression level of ROCK1. ROCK1 overexpression caused no evident effects on lncRNA HAND2-AS1 expression, but promoted cancer cell proliferation and decreased the effects of lncRNA HAND2-AS1 overexpression on cancer cell proliferation. Thus, it is possible that lncRNA HAND2-AS1 overexpression leads to inhibited cancer cell proliferation in melanoma cells through the downregulation of ROCK1.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC), is the third leading cause of cancer-related death. MicroRNA-506 (miR-506) has been reported to exhibit abnormal expression in HCC; however, the role of miR-506 in HCC and the molecular mechanisms underlying miR-506 in HCC remain unclarified. METHODS Quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay was performed to detect the expression of miR-506 and Rho associated coiled-coil containing protein kinase 2 (ROCK2). Cell proliferation and apoptosis were evaluated by MTT assay and flow cytometry, respectively. Bioinformatics analysis and luciferase reporter assays were performed to identify the regulation between miR-506 and ROCK2. Western blot assay was performed to detect the expression of ROCK2, RhoA, and Ras-related C3 botulinum toxin substrate 1 (Rac1). The tumor growth in vivo was evaluated in a HCC xenograft mice model. RESULTS The mRNA levels of ROCK2 were significantly upregulated, while miR-506 levels were significantly downregulated in HCC tissues and cells. The expression of ROCK2 was negatively correlated with miR-506 in HCC tissues. In vitro, upregulation of miR-506 inhibited proliferation and induced apoptosis, and downregulation of miR-506 promoted proliferation and blocked apoptosis in HepG2 and Hep3B cells. ROCK2 was a target gene of miR-506 and miR-506 regulated the expression of ROCK2 in HepG2 and Hep3B cells. Furthermore, downregulation of miR-506 partially attenuated the tumor-suppressive effect of ROCK2 knockout on HepG2 and Hep3B cells, and upregulation of miR-506 partially attenuated the oncogenic effect of ROCK2 overexpression on HepG2 and Hep3B cells; Overexpression of ROCK2 increased and ROCK2 knockdown decreased the expression of Rac1, which were attenuated by upregulation of miR-506 or downregulation of miR-506, respectively. In addition, ROCK2 overexpression or knockdown hadno significant effect on RhoA expression. In vivo, upregulation of miR-506 suppressed tumor growth, while downregulation of miR-506 promoted tumor growth. CONCLUSION miR-506 was involved in cell proliferation and apoptosis by affecting RhoA/ROCK signaling pathway in HCC cells. Our results provide a novel mechanism of miR-506-mediated suppressive effects on HCC tumorigenesis.

Abstract
Mitogen-activated protein kinase-activated protein kinase 2 (MK2) and its mediated inflammation are involved in various diseases, including spinal cord injury (SCI). Ultrashortwave (USW) radiation has previously been reported to exert a protective effect on SCI. In the present study, through a series of reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blot and immunofluorescence assay, it was found that MK2 and tumor necrosis factor (TNF)-α/interleukin (IL)-1β were elevated in patients with SCI and in H2O2-treated C8-D1A cells. Through gene level and protein level detection by using of RT-qPCR, western blot, immunofluorescence assay and terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling assay, it was demonstrated that USW radiation inhibited the expression of MK2/TNF-α/IL-1β and suppressed the apoptosis of H2O2-treated C8-D1A cells. Furthermore, it was confirmed that the overexpression of MK2 reversed the protective effect of USW on C8-D1A cells, which indicated that USW achieved its function via regulation of the MK2/TNF-α/IL-1β pathway. Finally, using a constructed in vivo model and a series of RT-qPCR, western blot and IHC detection, it was confirmed that USW suppressed the expression of MK2 to promote functional recovery following SCI. The findings of the present study may provide a novel target and improve on the current understanding of how USW functions in the treatment of SCI.

Abstract
Diabetic wounds are recalcitrant to healing. However, the mechanism causing this dysfunction is not fully understood. High expression of matrix metalloproteinase-9 (MMP-9) is indicative of poor wound healing. In this study, we show that specificity protein-1 (Sp1), a regulator of MMP-9, binds directly to its promoter and enhances its expression. Additionally, we demonstrated that Sp1 is the direct target of two microRNAs (miRNAs), miR-129 and -335, which are significantly downregulated in diabetic skin tissues. In vitro experiments confirmed that miR-129 or -335 overexpression inhibits MMP-9 promoter activity and protein expression by targeting Sp1, whereas the inhibition of these miRNAs has the opposite effect. The beneficial role of miR-129 or miR-335 in diabetic wound healing was confirmed by the topical administration of miRNA agomirs in diabetic animals. This treatment downregulated Sp1-mediated MMP-9 expression, increased keratinocyte migration, and recovered skin thickness and collagen content. The combined treatment with miR-129 and miR-335 induced a synergistic effect on Sp1 repression and MMP-9 downregulation both in vitro and in vivo. This study demonstrates the regulatory mechanism of Sp1-mediated MMP-9 expression in diabetic wound healing and highlights the potential therapeutic benefits of miR-129 and -335 in delayed wound healing in diabetes.

Long noncoding RNA DANCR, working as a competitive endogenous RNA, promotes ROCK1-mediated proliferation and metastasis via decoying of miR-335-5p and miR-1972 in osteosarcoma. Mol Cancer 2018; 17:89. [PMID: 29753317 PMCID: PMC5948795 DOI: 10.1186/s12943-018-0837-6] [Citation(s) in RCA: 179] [Impact Index Per Article: 29.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Accepted: 04/25/2018] [Indexed: 12/15/2022] Open
Abstract
Background Accumulating evidences indicate that non-coding RNAs (ncRNAs) including long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) acting as crucial regulators in osteosarcoma (OS). Previously, we reported that Rho associated coiled-coil containing protein kinase 1 (ROCK1), a metastatic-related gene was negatively regulated by microRNA-335-5p (miR-335-5p) and work as an oncogene in osteosarcoma. Whether any long non-coding RNAs participate in the upstream of miR-335-5p/ROCK1 axial remains unclear. Methods Expression of differentiation antagonizing non-protein coding RNA (DANCR) and miR-335-5p/miR-1972 in osteosarcoma tissues were determined by a qRT-PCR assay and an ISH assay. Osteosarcoma cells’ proliferation and migration/invasion ability changes were measured by a CCK-8/EDU assay and a transwell assay respectively. ROCK1 expression changes were checked by a qRT-PCR assay and a western blot assay. Targeted binding effects between miR-335-5p/miR-1972 and ROCK1 or DANCR were verified by a dual luciferase reporter assay and a RIP assay. In vivo experiments including a nude formation assay as well as a CT scan were applied to detect tumor growth and metastasis changes in animal level. Results In the present study, an elevated DNACR was found in osteosarcoma tissue specimens and in osteosarcoma cell lines, and the elevated DNACR was closely correlated with poor prognosis in clinical patients. Functional experiments illustrated that a depression of DANCR suppressed ROCK1-mediated proliferation and metastasis in osteosarcoma cells. The results of western blot assays and qRT-PCR assays revealed that DANCR regulated ROCK1 via crosstalk with miR-335-5p and miR-1972. Further cellular behavioral experiments demonstrated that DNACR promoted ROCK1-meidated proliferation and metastasis through decoying both miR-335-5p and miR-1972. Finally, the outcomes of in vivo animal models showed that DANCR promoted tumor growth and lung metastasis of osteosarcoma. Conclusions LncRNA DANCR work as an oncogene and promoted ROCK1-mediated proliferation and metastasis through acting as a competing endogenous RNA (ceRNA) in osteosarcoma.

Abstract
Many studies have shown that microRNA regulates the development and treatment of osteosarcoma (OS). In many human cancer studies, the expression of microRNA-202 has been shown to be abnormal. The aim of the study was to examine the role of miR-202-5p in the occurrence and formation of OS. miR-202-5p and Rho-associated coiled-coil containing protein kinase 1 (ROCK1) levels were assessed using RT-qPCR in OS tissues and cell lines. The cell migrating and invasive abilities were detected by the Transwell assay in OS. Moreover, the relationship between miR-202-5p and ROCK1 was verified via luciferase reporter assay. The protein level of ROCK1 was identified by western blot analysis. Downregulation of miR-202-5p was identified in OS tissues and cell lines. In addition, the miR-202-5p overexpression had inhibitory action for cell migration and invasion in OS. Moreover, miR-202-5p directly targeted ROCK1 and negatively regulated its expression. Upregulation of ROCK1 had a carcinogenic effect in OS. Furthermore, the upregulation of ROCK1 restored the suppressive effect of miR-202-5p. miR-202-5p, in turn, weakened the abilities of cell migration and invasion in OS by inhibiting ROCK1 expression. As a result, miR-202-5p may be developed as a potential pathway in the reatment of OS.

Abstract
Long non-coding RNAs (lncRNAs) play key roles in various malignant tumors, including colorectal cancer (CRC). Long non-coding RNA differentiation antagonizing non-protein coding RNA (DANCR) is overexpressed in CRC patients, but whether it affects CRC proliferation and metastasis via regulation of heat shock protein 27 (HSP27) remains unclear. In the present study, we found that DANCR was highly expressed and correlated with proliferation and metastasis in CRC. In addition, we demonstrated that DANCR and HSP27 were both targets of microRNA-577 (miR-577) and shared the same binding site. Furthermore, we revealed that DANCR promoted HSP27 expression and its mediation of proliferation/metastasis via miR-577 sponging. Finally, using an in vivo study, we confirmed that overexpression of DANCR promoted CRC tumor growth and liver metastasis. The present study demonstrated the function of DANCR in CRC and might provide a new target in the treatment of CRC.

Abstract
Spinal cord injuries are common and troublesome disorder, which is mediated by various signal pathways and mechanisms. MK2 is also involved in numerous inflammatory diseases including spinal cord injury. The role of microRNA-137 (miR-137) and its detailed working mechanism in spinal cord injuries remain unclear. In the present study, we found that an elevated MK2 but a decreased miR-137 was expressed in serum specimens of patients with spinal cord injury and in hydrogen peroxide-treated C8-D1A and C8-B4 cells. Meanwhile, we suggested that upregulation of miR-137 could inhibit the expression of TNF-α and IL-6, two markers of inflammatory response after SCI, and apoptosis in hydrogen peroxide-treated C8-D1A and C8-B4 cells. Furthermore, we verified that MK2 was a direct target of miR-137 thorough a constructed luciferase assay. Even further, we elucidated that miR-137 could suppress the inflammatory response and apoptosis via negative regulation of MK2. Finally, through an animal model trial performed using mice, we demonstrated the protective effect of how miR-137 works on inflammatory response and apoptosis after spinal cord injury. Considering all the forementioned, our findings revealed that miR-137 inhibited inflammatory response and apoptosis after spinal cord injury via the targeting of MK2. The outcomes of the present study might indicate a new target in molecular treatment of SCI.

[PMID: 29161765 PMCID: PMC5797811 DOI: 10.1111/cas.13452] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2017] [Revised: 10/31/2017] [Accepted: 11/16/2017] [Indexed: 12/31/2022] Open
Abstract
Accumulating evidence has suggested that the dysregulation of miRNA is an important factor in the pathogenesis of lung cancer. Here, we demonstrate that miR-335 expression is reduced in non-small cell lung cancer (NSCLC) tumors relative to non-cancerous adjacent tissues, while the expression of Tra2β is increased. In addition, clinical data revealed that the increased Tra2β and decreased miR-335 expression observed in NSCLC cells was associated with poor patient survival rates. In vitro experimentation showed that the overexpression of miR-335 inhibited the growth, invasion and migration capabilities of A459 lung cancer cells, by targeting Tra2β. In contrast, inhibition of miR-335 or overexpression of the Tra2β target gene stimulated the growth, invasion and migratory capabilities of A459 lung cancer cells in vitro. Furthermore, overexpression of miR-335 or inhibition of Tra2β decreased the phosphorylation of Rb-S780 and Rb-AKT. Overall, these findings suggest that the downregulation of miR-335 in A459 lung cancer cells promoted cell proliferation through upregulation of Tra2β, mediated via activation of the AKT/mTOR signaling pathway, and suggest that miR-335 may have potential as a novel therapeutic target for NSCLC.
