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.

[PMID: 35473680 PMCID: PMC9044806 DOI: 10.1186/s12890-022-01957-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 04/19/2022] [Indexed: 11/16/2022] Open
Abstract
Background Sevoflurane is considered as a lung-protective factor in acute lung injury (ALI), but the underlying molecular mechanism remains largely unknown. The present study identified for the first time that sevoflurane ameliorated lipopolysaccharide (LPS)-induced ALI through regulating a novel long non-coding RNA LINC00839, and uncovered its regulatory mechanism. Methods LPS-induced ALI models were established in mice or mouse pulmonary microvascular endothelial cells (MPVECs), and they were administered with sevoflurane. Real-Time quantitative PCR, western blot and bioinformatics analysis were performed to screen the aberrantly expressed long non-coding RNA and the downstream molecules in sevoflurane-treated ALI models, and their roles in the protection effect of sevoflurane were verified by functional recovery experiments. Results Sevoflurane relieved LPS-induced lung injury, cell pyroptosis and inflammation in vitro and in vivo. LINC00839 was significantly suppressed by sevoflurane, and overexpression of LINC00839 abrogated the protective effects of sevoflurane on LPS-treated MPVECs. Mechanismly, LINC00839 positively regulated NOD-like receptor protein 3 (NLRP3) via sequestering miR-223. MiR-223 inhibitor reversed the inhibitory effects of LINC00839 knockdown on NLRP3-mediated pyroptosis in LPS-treated MPVECs. Furthermore, both miR-223 ablation and NLRP3 overexpression abrogated the protective effects of sevoflurane on LPS-treated MPVECs. Conclusion In general, our work illustrates that sevoflurane regulates the LINC00839/miR-223/NLRP3 axis to ameliorate LPS-induced ALI, which might provide a novel promising candidate for the prevention of ALI.

Wogonin inhibits inflammation and apoptosis through STAT3 signal pathway to promote the recovery of spinal cord injury. Brain Res 2022; 1782:147843. [PMID: 35202619 DOI: 10.1016/j.brainres.2022.147843] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/15/2022] [Accepted: 02/17/2022] [Indexed: 01/29/2023]
Abstract
Spinal cord injury (SCI) is a complex central traumatic disease. STAT3 signal transduction pathway plays an important role in SCI. Wogonin has been reported to exhibit neuroprotection. However, the molecular mechanism of its potential therapeutic effect after SCI remains unclear. In this study, rats were divided into the following groups: Sham; SCI; SCI + wogonin; and SCI + wogonin + colivelin (Colivelin is an effective activator of the STAT3 pathway). Motor function was evaluated by Basso Beattie Bresnahan (BBB) score. Histomorphological changes in the spinal cords were observed by Hematoxylin-eosin (HE) staining and Nissl staining. Western blot, Transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining, and immunofluorescence were used to detect changes in the neuronal inflammation, apoptosis, and STAT3 signal pathway. Western blot and immunofluorescence techniques were also performed to detect the regulatory effect and the underlying mechanism of wogonin on the inflammation and apoptosis of PC12 cells. Experimental results in vivo and in vitro showed that wogonin could promote the recovery of motor function, improve the histopathological morphology, inhibit the activation of the STAT3 signal pathway, and reduce the neuronal inflammation and apoptosis in the rats with SCI. Activation of the STAT3 signal pathway by colivelin reversed the therapeutic effect of wogonin. Therefore, wogonin could inhibit inflammation and apoptosis by inhibiting the STAT3 signal pathway and promote the functional recovery of rats with SCI.

Abstract
ABSTRACT Atherosclerosis (AS) is the common pathological basis of cardiovascular disease. Circular RNA circ-USP9X (hsa_circ_0090231) has been discovered to be upregulated in oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs), but the role of circ-USP9X in ox-LDL-induced endothelial cell injury is indistinct. The purpose of the research was to investigate the role and regulatory mechanism of circ-USP9X in ox-LDL--induced endothelial cell injury. Expression of circ-USP9X was examined by quantitative real-time polymerase chain reaction. Loss-of-function experiments were performed to assess the impacts of circ-USP9X inhibition on viability, cell cycle progression, apoptosis, and tube formation, inflammation, and oxidative stress of ox-LDL-induced HUVEC. The regulatory mechanism of circ-USP9X predicted by bioinformatics analysis and verified by dual-luciferase reporter or RNA immunoprecipitation assays. We observed that circ-USP9X was upregulated in AS patients' serum and ox-LDL-induced HUVEC. Inhibition of circ-USP9X elevated viability, promoted cell cycle progression and angiopoiesis, and decreased apoptosis, inflammation, and oxidative stress of ox-LDL-induced HUVEC. Mechanically, circ-USP9X regulated chloride intracellular channel 4 (CLIC4) messenger RNA expression by sponging microRNA (miR)-599. Furthermore, miR-599 inhibitor overturned circ-USP9X silencing-mediated influence on ox-LDL-induced HUVEC injury. Also, CLIC4 overexpression reversed miR-599 elevation-mediated effect on ox-LDL-induced HUVEC injury. In conclusion, circ-USP9X silencing decreased ox-LDL-induced endothelial cell injury via the miR-599/CLIC4 axis, which offered a novel molecular mechanism to comprehend the pathology of AS.

MiRNAs Correlate with HLA Expression in Uveal Melanoma: Both Up- and Downregulation Are Related to Monosomy 3. Cancers (Basel) 2021; 13:cancers13164020. [PMID: 34439175 PMCID: PMC8393554 DOI: 10.3390/cancers13164020] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Revised: 08/04/2021] [Accepted: 08/06/2021] [Indexed: 12/31/2022] Open
Abstract
Simple Summary Uveal melanoma (UM) is a rare ocular malignancy that often gives rise to metastases. Tumours with an inflammatory phenotype have an especially bad prognosis. As an increased HLA expression and the presence of tumour-infiltrating lymphocytes and macrophages may be regulated by miRNAs, we set out to investigate whether any miRNAs are associated with inflammatory parameters in this malignancy. Some miRNAs were increased in UM with a high HLA expression and high T cell numbers, while others were decreased, showing two opposing patterns; however, both patterns were related to the tumour’s chromosome 3/BAP1 status. We conclude that specific miRNAs are related to the inflammatory phenotype and that these are differentially expressed between disomy 3/BAP1-positive versus monosomy 3/BAP1-negative UM. Abstract MicroRNAs are known to play a role in the regulation of inflammation. As a high HLA Class I expression is associated with a bad prognosis in UM, we set out to determine whether any miRNAs were related to a high HLA Class I expression and inflammation. We also determined whether such miRNAs were related to the UM’s genetic status. The expression of 125 miRNAs was determined in 64 primary UM from Leiden. Similarly, the mRNA expression of HLA-A, HLA-B, TAP1, BAP1, and immune cell markers was obtained. Expression levels of 24 of the 125 miRNAs correlated with expression of at least three out of four HLA Class I probes. Four miRNAs showed a positive correlation with HLA expression and infiltration with leukocytes, 20 a negative pattern. In the first group, high miRNA levels correlated with chromosome 3 loss/reduced BAP1 mRNA expression, in the second group low miRNA levels. The positive associations between miRNA-22 and miRNA-155 with HLA Class I were confirmed in the TCGA study and Rotterdam cohort, and with TAP1 in the Rotterdam data set; the negative associations between miRNA-125b2 and miRNA-211 and HLA-A, TAP1, and CD4 were confirmed in the Rotterdam set. We demonstrate two patterns: miRNAs can either be related to a high or a low HLA Class I/TAP1 expression and the presence of infiltrating lymphocytes and macrophages. However, both patterns were associated with chromosome 3/BAP1 status, which suggests a role for BAP1 loss in the regulation of HLA expression and inflammation in UM through miRNAs.

Abstract
Long noncoding RNAs (lncRNAs) have been reported to be implicated in various biological and pathological processes. However, the function and mechanism of XIST in vascular smooth muscle cells (VSMCs) remains unknown. The levels of XIST, miR-599, and TLR4 were tested by RT-qPCR. VSMCs and human mononuclear cells (U937) treated with ox-LDL were used as atherosclerosis (AS) cell models. The CCK-8 assay was adopted to detect cell viability. Cell apoptosis was examined by the TUNEL assay. A dual-luciferase reporter assay was employed to investigate the interaction between miR-599 and XIST or TLR4. In this research, we uncovered that the XIST level was elevated in the serum of AS patients and ox-LDL-treated AS cell models. Functional analysis revealed that XIST depletion restrained cell proliferation, while induced the apoptosis in AS cell models. Besides, miR-599 was verified to be a direct downstream target of XIST and miR-599 inhibitor reversed the effects of XIST knockdown on AS progression. Finally, we demonstrated that XIST increased TLR4 expression by serving as a ceRNA of miR-599. All these findings manifested the role of the XIST/miR-599/TLR4 axis in AS development.

Mol Med Rep 2020; 23:145. [PMID: 33325534 PMCID: PMC7751488 DOI: 10.3892/mmr.2020.11784] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 10/08/2020] [Indexed: 12/13/2022] Open
Abstract
The incidence of allergic rhinitis (AR) is increasing worldwide. Human nasal epithelial cells (HNECs) are the key cells in the occurrence of AR. Antisense non-coding RNA in the INK4 locus (ANRIL) was discovered to be involved in the progression of AR. However, the mechanism by which ANRIL mediates the progression of AR remains to be determined. The present study aimed to further explore the mechanism by which ANRIL regulates AR. Thereby, HNECs were treated with IL-13 to mimic AR in vitro. The mRNA expression levels of ANRIL, microRNA (miR)-15a-5p, JAK2, mucin 5AC (MUC5AC), granulocyte-macrophage colony-stimulating factor (GM-CSF) and eotaxin-1, and protein expression levels of JAK2, STAT3 and phosphorylated-STAT3 in HNECs were analyzed using reverse transcription-quantitative PCR and western blotting, respectively. ELISAs were used to detect the secretory levels of inflammatory cytokines and mucin in cell supernatants. In addition, a dual luciferase reporter assay was used to confirm the downstream target of ANRIL and the target gene of miR-15a-5p. The results revealed that the secretory levels of eotaxin-1, GM-CSF and MUC5AC were significantly upregulated by IL-13 in the supernatant of HNECs. The expression levels of ANRIL and JAK2 were also upregulated in IL-13-induced HNECs, while the expression levels of miR-15a-5p were downregulated. In addition, ANRIL was identified to bind to miR-15a-5p. The IL-13-induced upregulation of eotaxin-1, GM-CSF and MUC5AC mRNA expression and secretory levels was significantly inhibited by the genetic knockdown of ANRIL, while the miR-15a-5p inhibitor effectively reversed this effect. JAK2 was also discovered to be directly targeted by miR-15a-5p. The overexpression of JAK2 significantly suppressed the therapeutic effect of miR-15a-5p mimics on IL-13-induced inflammation in vitro. In conclusion, the findings of the present study suggested that the genetic knockdown of ANRIL may suppress the production of inflammatory cytokines and mucin in IL-13-treated HNECs via regulation of the miR-15a-5p/JAK2 axis. Thus, ANRIL may serve as a novel target for AR treatment.

Abstract
Osteoarthritis (OA) is an ageing‐related disease characterized by articular cartilage degradation and joint inflammation. circRNA has been known to involve in the regulation of multiple inflammatory diseases including OA. However, the mechanism underlying how circRNA regulates OA remains to be elucidated. Here, we report circANKRD36 prevents OA chondrocyte apoptosis and inflammation by targeting miR‐599, which specifically degrades Casz1. We performed circRNA sequencing in normal and OA tissues and found the expression of circANKRD36 is decreased in OA tissues. circANKRD36 is also reduced in IL‐1β–treated human chondrocytes. FACS analysis and Western blot showed that the knockdown of circANKRD36 promotes the apoptosis and inflammation of chondrocytes in IL‐1β stress. We then found miR‐599 to be the target of circANKRD36 and correlate well with circANKRD36 both in vitro and in vivo. By database analysis and luciferase assay, Casz1 was found to be the direct target of miR‐599. Casz1 helps to prevent apoptosis and inflammation of chondrocytes in response to IL‐1β. In conclusion, our results proved circANKRD36 sponge miR‐599 to up‐regulate the expression of Casz1 and thus prevent apoptosis and inflammation in OA.

Abstract
Non-alcoholic fatty liver disease (NAFLD) has become a common chronic disease in the world. NAFLD is not only a simple intrahepatic lesion, but also affects the occurrence of a variety of extrahepatic complications. In particular, cardiovascular complications are particularly serious, which is the main cause of death in patients with NAFLD. To study the relationship between NAFLD and AS may be a new way to improve the quality of life in patients with NAFLD. As we all known, inflammatory response plays an important role in the occurrence and development of NAFLD and AS. In this study, we found that the accumulation of Nε-carboxymethyllysine (CML) in the liver leads to hepatic steatosis. CML can induce the expression of interleukin (IL-1β), interleukin (IL-6), tumor necrosis factor (TNF-α), C-reactionprotein (CRP) by binding with advanced glycosylation end-product receptor (RAGE) and accelerate the development of AS. After silencing RAGE expression, the expression of pro-inflammatory cytokines was inhibited and liver and aorta pathological changes were relieved. In conclusion, CML/RAGE signal promotes the progression of non-alcoholic fatty liver disease and atherosclerosis. We hope to provide new ideas for the study of liver vascular dialogue in multi organ communication.
