Chen F, Li S, Wu J, Guo Q, Wang H, Ni B, Yang J. Exosomes derived from Mouse Bone Marrow Mesenchymal Stem Cells Attenuate Nucleus Pulposus Cell Apoptosis via the miR-155- 5p/Trim32 Axis. Curr Mol Med 2024; 24:1045-1055. [PMID: 37587825 DOI: 10.2174/1566524023666230816090843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 05/30/2023] [Accepted: 05/31/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND Lower back pain, shown to be strongly associated with IVDD, affects approximately 60%-80% of adults and has a considerable societal and economic impact. Evidence suggests that IVDD, caused by abnormal apoptosis of nucleus pulposus cells (NPCs), can be treated using MSC-derived exosomes. OBJECTIVE This study aimed to evaluate the role of miR155-5p/Trim32 in intervertebral disc disease (IVDD) and elucidate the underlying molecular mechanisms. Deregulating miR-155 has been shown to promote Fas-mediated apoptosis in human IVDD. Evidence also suggests that tripartite motif (TRIM)-containing protein 32 (Trim32) is regulated by miR-155. However, the role of miR155-5p/Trim32 in IVDD remains unclear. METHODS Cell viability was checked using CCK-8 kits, and flow cytometry was used to analyze cell cycle and apoptosis. Cell migration was measured with a Transwell assay, while a luciferase assay was adopted to study how miR-155-5p interacts with Trim32. The roles of Trim32 and miR-155-5p were studied by silencing or up-regulating them in NPCs, while qPCR and immunoblots were used to evaluate mRNA and protein changes, respectively. RESULTS TNF-α treatment significantly inhibited cell viability but promoted Trim32 expression in primary mouse NPCs. Administration of bone marrow mesenchymal stem cells (BMSCs) attenuated primary NPC cell cycle arrest and apoptosis induced by TNF- α. BMSCs-derived exosomes could be taken up by NPCs to inhibit TNF-α-induced cell cycle arrest and apoptosis through miR-155-5p. Examination of the underlying mechanism showed that miR-155-5p targeted Trim32. Moreover, Trim32 overexpression inhibited the effect of BMSCs-derived exosomes on primary mouse NPC cell apoptosis induced by TNF-α. CONCLUSION Overall, these findings suggest that exosomes from BMSCs can suppress TNF-α-induced cell cycle arrest and apoptosis in primary mouse NPCs through the delivery of miR-155-5p by targeting Trim32. This study provides a promising therapeutic strategy for IVDD.

Apigenin reduces the suppressive effect of exosomes derived from irritable bowel syndrome patients on the autophagy of human colon epithelial cells by promoting ATG14. World J Surg Oncol 2023; 21:95. [PMID: 36915121 PMCID: PMC10012571 DOI: 10.1186/s12957-023-02963-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 02/25/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Inflammatory bowel disease (IBS) is a chronic disorder of the gastrointestinal tract. Exosomes have been involved in various pathological processes including IBS. Apigenin has been reported to suppress inflammatory bowel disease (IBS). However, the regulatory roles of exosomes derived from IBS patients (IBS-exos) on human colon epithelial cells are still unclear. METHODS Exosomes were collected from IBS patients (IBS-exos) and co-cultured with CACO-2 cells. Apigenin was used to treat IBS-exos-treated CACO-2 cells. By exploring the public data bank, we figured out the regulators control the autophagy of CACO-2 cells. RESULTS Administration of apigenin dose-dependently abolished the inhibitory effect of IBS-exo on the autophagy of CACO-2 cells. A mechanistic study showed that miR-148b-3p bound to 3'UTR to suppress ATG14 and decrease autophagy. Moreover, results suggested that ATG14 overexpression promoted the autophagy of CACO-2 cells in the presence of miR-148b-3p mimic. CONCLUSION The current study showed that apigenin dose-dependently abolished the inhibitory effect of IBS-exo on CACO-2 cell autophagy by regulating miR-148b-3p/ATG14 signaling.

Abstract
Sepsis is one of the leading causes of morbidity and mortality and a major cause of acute lung injury (ALI). carried by exosomes play a role in a variety of diseases. However,there are not many studies of exosomal miRNAs in sepsis and sepsis lung injury.miR-1298-5p and suppressor of cytokine signaling 6 (SOCS6) were silenced or overexpressed in human bronchial epithelial cells (BEAS-2B). PKH-67 Dye was used to trace exosome endocytosis. Cell permeability was evaluated by measuring trans-epithelial electrical resistance (TEER) and FITC dextran flux. ELISA kits were used for cytokine detection. Quantitative RT-PCR and western blots were used to evaluate gene expression. miR-1298-5p was elevated in exosomes from patients with sepsis lung injury (Sepsis_exo). Treatment of BEAS-2B cells using Sepsis_exo significantly inhibited cell proliferation, and induced cell permeability and inflammatory response. miR-1298-5p directly targeted SOCS6. Overexpressing SOCS6 reversed miR-1298-5p-induced cell permeability and inflammatory response. Inhibition of STAT3 blocked SOCS6-silencing caused significant increase of cell permeability and inflammation. Exosomes isolated from patients of sepsis lung injury increased cell permeability and inflammatory response in BEAS-2B cells through exosomal miR-1298-5p which targeted SOCS6 via STAT3 pathway. The findings highlight the importance of miR-1298-5p/SOCS6/STAT3 axis in sepsis lung injury and provide new insights into therapeutic strategies for sepsis lung injury.

Abstract
Cervical cancer is one of the most malignant tumors in women. miR-1298 was reported to be abnormally expressed and serve crucial role in tumorigenesis of several types of cancer; however, the role of miR-1298 in cervical cancer remains unknown. The present study aimed to evaluate the clinical and biological significance of miR-1298 in cervical cancer. To do so, the expression level of miR-1298 in cervical cancer tissues and cells was evaluated by reverse transcription quantitative PCR. Kaplan-Meier survival analysis and Cox regression analysis were used to explore the prognostic significance of miR-1298 in patients with cervical cancer. Cell Counting Kit-8 and Transwell migration and invasion assays were used to evaluate the effect of miR-1298 on the proliferative, migratory and invasive abilities of cervical cancer cells, respectively. The expression of miR-1298 was lower in cancer tissues and cells compared with normal tissues and cells. Furthermore, miR-1298 expression was associated with lymph node metastasis, tumor diameter and staging from the International Federation of Gynecology and Obstetrics. In addition, patients with low miR-1298 expression had poorer overall survival. These findings suggested that miR-1298 may be considered as an independent prognostic factor for patients with cervical cancer. Furthermore, the results demonstrated that miR-1298 knockdown could promote tumor cell proliferation and migratory and invasive abilities. In addition, nucleus accumbens-associated 1 (NACC1) was demonstrated to be a direct target of miR-1298. Taken together, these findings indicated that miR-1298 overexpression may be considered as a prognostic biomarker for cervical cancer and that miR-1298 may play an inhibitor role in cervical cancer by targeting NACC1.

Abstract
Purpose In recent years, traditional Chinese medicine has achieved good results in treating gliomas. This research aimed to reveal the effect of Shezhi Huangling decoction (SD) on glioma cell process. Methods U87 and U251 cells were treated with different concentrations (10, 30 and 50 μg/mL) of SD or transfected with miR-1298-5p mimic, inhibitor and siRNA targeting TGIF1. Cell proliferation, migration, invasion and apoptosis were detected. The expression of miR-1298-5p was measured by qRT-PCR, while TGIF1 expression was examined by immunohistochemical analysis and Western blot. Results SD treatment inhibited the proliferation, migration and invasion of glioma cells and induced the apoptosis. In addition, SD treatment induced the expression of miR-1298-5p in glioma cells. The low expression of miR-1298-5p was examined in glioma tissues and was significantly related to the high histological grade of glioma patients and predicted a poor prognosis. MiR-1298-5p directly targeted the 3'-UTR of transforming growth factor β induced factor 1 (TGIF1) and reduced TGIF1 protein expression. MiR-1298-5p restricted the proliferation, migration and invasion of glioma cells and induced cell apoptosis by targeting TGIF1. Conclusion Our data reveal that SD acts as a cancer-inhibiting agent in glioma via miR-1298-5p/TGIF1 axis, suggesting a potential therapeutic application of SD in glioma.

Abstract
MicroRNA (miR)-1298 is widely down-regulated in a variety of malignant tumors, which facilitates cell proliferation, invasiveness, and migration. However, the specific biological function of miR-1298 in bladder cancer (BC) is still unknown. Connexin 43 (Cx43) is often up-regulated in tumors. Identifying miRNAs that target Cx43 in the setting of BC will help to develop Cx43-based therapies for BC. In this study, the results demonstrated that the expression levels of miR-1298 and Cx43 were significantly down-regulated and up-regulated, respectively, in BC tissues. Overexpression of miR-1298 inhibited cell proliferation, migration, and invasiveness in two BC cell lines as determined using MTT assays, cell cycle assays, colony formation assays, Transwell assays, gelatin zymography, and Western blot. In addition, we found that miR-1298 decreased Cx43 expression by directly targeting the 3'-UTR. Further, we observed that the promotion of BC cell proliferation, migration, and invasiveness from Cx43 on could be partially attenuated by overexpressing miR-1298. Moreover, the protein expression of p-ERK was ameliorated after transfection with overexpressed-miR-1298. Knockdown of Cx43 reversed the promotion of cell migration and invasiveness due to decreased expression of miR-1298. All of the data from our study indicate that miR-1298 could be a diagnostic marker of BC and a potential therapeutic agent via inhibiting Cx43.

Abstract
The enormous cost of modern medicines warrants alternative strategies for the better management of hepatocellular carcinoma. Recently, exosomes have been shown to relay the oncogenic information through the horizontal transfer of RNAs between the cells. In this study, we modulated exosomal production and autophagy (exophagy) by the administration of hesperidin and evaluated its effect on the development of hepatic precancerous lesion (HPC) in rats. Diethylnitrosamine and 2-acetylaminofluorene were used in vivo to induce HPC in rats. Rats were allocated into five groups: naïve, HPC, and three hesperidin treated (50, 100, and 200 mg/kg/d; orally) for 4 consecutive days per week for 16 weeks. Liver tissues and blood samples were collected for histopathological, immunohistochemical, and transmission electron microscope examinations, liver function, alfa-fetoprotein level, and isolation of exosomal and autophagy RNAs. Hesperidin administration showed hepato-protective effects and improved the microscopic hepatic features with a decrease in glutathione S-transferase placental precancerous foci and the abundance of exosomes in liver tissues. Hesperidin improved liver function with a significant decrease in alfa-fetoprotein levels. Hesperidin dose-dependently decreased exosomal RAB11A messsenger RNA and long noncoding RNA-RP11-583F2.2 along with the increase in exosomal miR-1298, involved in the exophagy process. In conclusion, hesperidin likely suppresses liver carcinogenesis in rat model via the modulation of exosomal secretion and autophagy.

Abstract
Hypoxic-ischemic encephalopathy (HIE) is a common neonatal disease that can lead to high neonatal mortality rates. Previous studies have indicated that microRNAs (miRs) may be involved in the pathogenesis of HIE; however, the specific mechanisms underlying their involvement require further investigation. The aim of the present study was to investigate the roles of miR-204 and its target gene killin p53 regulated DNA replication inhibitor (KLLN) in HIE using rat HIE models. Brain injury was induced by surgery and incubation of hypoxic incubator brain using 10-day-old pup rats. On day 3, rats were sacrificed, and the infarct size of the brain was determined using a tetrazolium chloride assay. Terminal deoxynucleotidyl transferase UTP nick-end labeling staining was performed to detect the cell death rate in the brain tissue. Following this, the brain tissues were collected, and reverse transcription-quantitative polymerase chain reaction, western blot analysis and immunohistochemistry assays were performed to examine the expression levels of miR-204 and KLLN. Furthermore, neurons were cultured and transfected with miR-204 inhibitors or mimics, and the effect of miR-204 on the proliferation and apoptosis of neurons was examined using MTT and flow cytometric assays. Finally, a dual-luciferase reporter assay was performed to confirm whether KLLN is a direct target of miR-204. The expression of miR-204 was significantly downregulated and the expression of KLLN was significantly increased in the brain tissue of HIE rats (P<0.001). In addition, the transfection with miR-204 inhibitors significantly decreased the proliferation rates and significantly increased the apoptosis rate of neurons; however, transfection with miR-204 mimics prompted the opposite results. The dual-luciferase reporter assay also confirmed that KLLN is a direct target of miR-204. Taken together, the results of the present study demonstrated that miR-204 was downregulated in HIE and that miR-204 may serve important roles in the pathogenesis of HIE through targeting KLLN.
