Abstract
Osteosarcoma (OS) has a high recurrence rate, disability rate, mortality and metastasis, it brings great economic burden and psychological pressure to patients, and then seriously affects the quality of life of patients. At present, the treatment methods of OS mainly include radiotherapy, chemotherapy, surgical therapy and neoadjuvant chemotherapy combined with limb salvage surgery. These treatment methods can relieve the clinical symptoms of patients to a certain extent, and also effectively reduce the disability rate, mortality and recurrence rate of OS patients. However, because metastasis of tumor cells leads to new complications, and OS cells become resistant with prolonged drug intervention, which reduces the sensitivity of OS cells to drugs, these treatments still have some limitations. More and more studies have shown that traditional Chinese medicine (TCM) has the characteristics of "multiple targets and multiple pathways," and can play an important role in the development of OS through several key signaling pathways, including PI3K/AKT, Wnt/β-catenin, tyrosine kinase/transcription factor 3 (JAK/STAT3), Notch, transforming growth factor-β (TGF-β)/Smad, nuclear transcription factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), nuclear factor E2-related factor 2 (Nrf2), Hippo/YAP, OPG/RANK/RANKL, Hedgehog and so on. In this paper, the signaling pathways of cross-interference between active ingredients of TCM and OS were reviewed, and the development status of novel OS treatment was analyzed. The active ingredients in TCM can provide therapeutic benefits to patients by targeting the activity of signaling pathways. In addition, potential strategies for targeted therapy of OS by using ferroptosis were discussed. We hope to provide a unique insight for the in-depth research and clinical application of TCM in the fields of OS growth, metastasis and chemotherapy resistance by understanding the signaling crosstalk between active ingredients in TCM and OS.

J Orthop Surg Res 2023; 18:848. [PMID: 37940978 PMCID: PMC10634167 DOI: 10.1186/s13018-023-04330-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 10/29/2023] [Indexed: 11/10/2023] Open
Abstract
BACKGROUND Osteosarcoma (OS) is a refractory malignancy. This study aimed to explore the roles and mechanisms of Inhibin subunit beta A (INHBA) in OS. METHODS INHBA expression levels in OS tissues and cells were assessed using RT-qPCR and western blotting. The impact of INHBA silencing on OS development was then explored by transfecting the OS cell lines U2OS and MG63 with INHBA-small interfering RNA (siRNA). The influence of INHBA silencing on U2OS and MG63 cell proliferation, migration, and invasion was examined using MTT and Transwell assays. Epithelial-mesenchymal transition (EMT) markers (E-cadherin and N-cadherin) were analyzed by RT-qPCR. The expression of genes involved in cell proliferation, migration, invasion, and the TGF-β signaling pathway was evaluated by western blotting and RT-qPCR. RESULTS INHBA levels were elevated in the OS tissues and cells. Furthermore, the transforming growth factor-β (TGF-β) signaling pathway of OS cells was suppressed in response to INHBA-siRNA, whereas proliferation, migration, and invasion of OS cells were inhibited. Besides, INHBA-siRNA significantly inhibited OS cell EMT, evidenced by enhanced E-cadherin mRNA expression and reduced N-cadherin mRNA expression. Further mechanistic studies revealed that the TGF-β1 agonist SRI-011381 hydrochloride increased OS cell proliferation, migration, and invasion after INHBA downregulation. CONCLUSION We found that INHBA silencing could play a vital role in OS via TGF-β1-regulated proliferation, migration, and invasion.

Abstract
Osteosarcoma (OS) is the predominant primary bone tumor in the pediatric and adolescent populations. It has high metastatic potential, with the lungs being the most common site of metastasis. In contrast to many other sarcomas, OS lacks conserved translocations or genetic mutations; instead, it has heterogeneous abnormalities, including somatic DNA copy number alteration, ploidy, chromosomal amplification, and chromosomal loss and gain. Unfortunately, clinical outcomes have not significantly improved in over 30 years. Currently, no effective molecularly targeted therapies are available for this disease. Several genomic studies showed inactivation in the tumor suppressor genes, including p53, RB, and ATRX, and hyperactivation of the tumor promoter genes, including MYC and MDM2, in OS. Alterations in the major signaling pathways, including the PI3K/AKT/mTOR, JAK/STAT, Wnt/β-catenin, NOTCH, Hedgehog/Gli, TGF-β, RTKs, RANK/RANKL, and NF-κB signaling pathways, have been identified in OS development and metastasis. Although OS treatment is currently based on surgical excision and systematic multiagent therapies, several potential targeted therapies are in development. This review focuses on the major signaling pathways of OS, and we propose a biological rationale to consider novel and targeted therapies in the future.

Abstract
Osteosarcoma is the most common malignant bone sarcoma in children. Chemotherapy drugs resistance significantly hinders the overall survival of patients. Due to high biocompatibility and immunocompatibility, exosomes have been explored extensively. Multiple parent cells can actively secrete numerous exosomes, and the membrane structure of exosomes can protect miRNAs from degradation. Based on these characteristics, exosomal miRNAs play an important role in the occurrence, development, drug resistance. Therefore, in-depth exploration of exosome biogenesis and role of exosomal miRNAs will provide new strategies and targets for understanding the pathogenesis of osteosarcoma and overcoming chemotherapy drug resistance. Moreover, advancing evidences have showed that engineering modification could attribute stronger targeting to exosomes to deliver cargos to recipient cells more effectively. In this review, we focus on the mechanisms of exosomal miRNAs on the occurrence and development of osteosarcoma and the potential to function as tumor biomarkers for diagnosis and prognosis prediction. In addition, we also summarize recent advances in the clinical application values of engineering exosomes to provide novel ideas and directions for overcoming the chemotherapy resistance in osteosarcoma.

Abstract
MicroRNAs (miRNAs or miRs) are involved in the development and progression of numerous types of cancer however their role in osteosarcoma has not been fully clarified. The present study aimed to use high-throughput bioinformatics analysis as well as in vitro experiments to investigate the potential role of transcription factors, miRNAs and their targets in the progression of osteosarcoma. miRNA data and clinical information of osteosarcoma were obtained from Gene Expression Omnibus database to investigate differentially expressed miRNAs. The expression of miRNAs/mRNAs in osteosarcoma cell lines was detected via reverse transcription-quantitative (RT-qPCR). MTT and colony formation assay were used to determine cell proliferation ability and transwell assay was used to observe cell invasion and migration ability. A total of four prediction algorithms for miRNA-mRNA interactions were used to determine potential target genes of miR-487a. Predicted target genes were used to intersect with overlapped differentially expressed genes (DEGs) from GSE12865 and The Cancer Genome Atlas osteosarcoma datasets. Expression of NK3 homeobox 1 (NKX3-1) was analyzed by western blotting and RT-qPCR assay. Dual luciferase assay was conducted to verify whether NKX3-1 was a direct target of miR-487a. The regulatory association between Kruppel-like factor 5 (KLF5) and miR-487a was detected using chromatin immunoprecipitation assay. miR-487a was upregulated in osteosarcoma tissue (GSE65071 and GSE28423) and cell lines (HOS and MG63). miR-487a mimic promoted proliferation, migration and invasion of osteosarcoma cells. NKX3-1 was a direct target of miR-487a and transfection of NKX3-1 plasmid reversed the effect of miR-487a on proliferation, migration and invasion of osteosarcoma cells. KLF5 enhanced miR-487a expression by directly binding to its promoter region and miR-487a inhibitor reversed the effect of KLF5 on proliferation, migration and invasion of osteosarcoma cells. The present results indicated that KLF5/miR-487a signaling promoted invasion and metastasis of osteosarcoma cells via targeting NKX3-1.

MicroRNAs and osteosarcoma: Potential targets for inhibiting metastasis and increasing chemosensitivity. Biochem Pharmacol 2022; 201:115094.

Abstract
Osteosarcoma (OS) is the third most common cancer in young adults after lymphoma and brain cancer. Metastasis, like other cellular events, is dependent on signaling pathways; a series of changes in some proteins and signaling pathways pave the way for OS cells to invade and migrate. Ezrin, TGF-β, Notch, RUNX2, matrix metalloproteinases (MMPs), Wnt/β-catenin, and phosphoinositide 3-kinase (PI3K)/AKT are among the most important of these proteins and signaling pathways. Despite the improvements in treating OS, the overall survival of patients suffering from the metastatic disease has not experienced any significant change after surgical treatments and chemotherapy and 5-years overall survival in patients with metastatic OS is about 20%. Studies have shown that overexpression or inhibition of some microRNAs (miRNAs) has significant effects in limiting the invasion and migration of OS cells. The results of these studies highlight the potential of the clinical application of some miRNA mimics and miRNA inhibitors (antagomiRs) to inhibit OS metastasis in the future. In addition, some studies have shown that miRNAs are associated with the most important drug resistance mechanisms in OS, and some miRNAs are highly effective targets to increase chemosensitivity. The results of these studies suggest that miRNA mimics and antagomiRs may be helpful to increase the efficacy of conventional chemotherapy drugs in the treatment of metastatic OS. In this article, we discussed the role of various signaling pathways and the involved miRNAs in the metastasis of OS, attempting to provide a comprehensive review of the literature on OS metastasis and chemosensitivity.

Abstract
Gastric cancer is a type of serious malignant tumors all around the world. TCGA data showed that the expression of TRIM65 (E3 ubiquitin ligase) was enhanced in the gastric cancer tissues. The role of TRIM65 in the tumorigenesis of gastric cancer remains unclear. In this study, we successfully established TRIM65-knockdown gastric cancer cells. Next, CCK-8, colony formation assays and transwell assays were performed to detect the cell proliferation and invasion. The results showed that suppression of TRIM65 inhibited the proliferation and invasion of gastric cancer cells. Interestingly, the Western blot assay confirmed that downregulation of TRIM65 increased the level of PPM1A and decreased the level of p-TBK1 in gastric cancer cells. Mechanistically, immunoprecipitation assay revealed that knockdown of TRIM65 inhibited the ubiquitin degradation of PPM1A. In rescue experiments, suppression of PPM1A promoted the proliferation and invasion of gastric cancer cells transfected with sh-TRIM65. Therefore, our results suggested that knockdown of TRIM65 inhibited the proliferation and invasion of gastric cancer cells by suppressing the ubiquitin degradation of PPM1A and phosphorylation of TBK1.

miR-522 regulates cell proliferation, migration, invasion capacities and acts as a potential biomarker to predict prognosis in triple-negative breast cancer. Clin Exp Med 2021; 22:385-392.

Abstract
This study was designed to explore the cell functions and prognostic significance of miR-522 in triple-negative breast cancer. The expression levels of miR-522 in triple-negative breast cancer tissues and cell lines were detected by quantitative real-time PCR analysis. Kaplan-Meier curve and Cox regression analysis were used to investigate the relationship between miR-522 expression and prognosis of patients, and to evaluate the possibility of miR-522 as a potential indicator for predicting the prognosis of triple-negative breast cancer. The CCK-8 and transwell assays were used to assess cell proliferation, migration, and invasion abilities. The expression of miR-522 in triple-negative breast cancer tissues was significantly higher than that in adjacent tissues and its high expression was closely associated with the high incidence of lymph node metastasis, advanced TNM stage, and BRCA1/2 mutation status. High expression of miR-522 is correlated with poor overall survival in patients with triple-negative breast cancer. Besides, functional studies in two triple-negative breast cancer cell lines showed that overexpression of miR-522 significantly promoted cell proliferation, migration, and invasion in vitro. BRCA1 was a potential direct target of miR-522. Our findings indicated that miR-522 was highly expressed in triple-negative breast cancer and was associated with poor prognosis of patients. The upregulation of miR-522 accelerated the progression of triple-negative breast cancer by targeting BRCA1. Therefore, miR-522 provides valuable information for the development of prevention and treatment strategies.

Abstract
Osteosarcoma (OS), a frequent malignant tumor which mainly occurs in the bone. The roles of long noncoding RNAs (lncRNAs) have been revealed in cancers, including OS. LncRNA long intergenic non-protein coding RNA (LINC00174) has been validated as an oncogene in several cancers. However, the role of LINC00174 in OS has not been explored. In our research, loss-of-function assays were conducted to explore the function of LINC00174 in OS cells. Then, we explored the downstream pathway of LINC00174 in OS cells. Bioinformatics, RNA pull-down and RIP experiments investigated the downstream mechanism of LINC00174 in OS cells. Finally, in vivo assays clarified the effect of LINC00174 on tumorigenesis. We found that LINC00174 was upregulated in OS tissues and cells. LINC00174 knockdown repressed OS cell growth. Mechanistically, LINC00174 knockdown suppressed the TGF-β/SMAD pathway. LINC00174 interacted with miR-378a-3p, and slingshot protein phosphatase 2 (SSH2) 3′UTR was targeted by miR-378a-3p in OS cells. Rescue assays showed that SSH2 upregulation or miR-378a-3p inhibition counteracted the inhibitory effect of LINC00174 depletion in OS cell growth. Additionally, LINC00174 depletion suppressed tumor growth in mice. In conclusion, LINC00174 promotes OS cellular malignancy and tumorigenesis via the miR-378a-3p/SSH2 axis and the TGF-β/SMAD pathway, which might provide a novel insight for OS treatment.

Abstract
The TP63 gene, which encodes the p63 protein, is involved in multiple biological processes, including embryonic development and tumorigenesis. ΔNp63α, the predominant isoform of p63 in epithelial cells, acts as an oncogene in early-stage tumors, but paradoxically acts as a potent antimetastatic factor in advanced cancers. Here, we report that ΔNp63α is a direct target of hsa-miR-522 (miR-522). Induced expression of miR-522 reduced the levels of ΔNp63α, predisposing breast epithelial cells to a loss of epithelial and acquisition of mesenchymal morphology, resulting in accelerated collective and single-cell migration. Restoration of ΔNp63α repressed miR-522-induced migration. Interestingly, overexpression of miR-522 did not affect breast epithelial cell proliferation, suggesting that miR-522 acts specifically through ΔNp63α in this context. Furthermore, expression of miR-522-3p and p63 was negatively correlated in human cancer samples. Thus, miR-522 might be a causative factor for breast tumorigenesis and cancer metastasis. In summary, our results reveal a novel miR-522/p63 axis in cell migration and thus suggest a potential strategy for therapeutic treatment of cancer metastasis.

[PMID: 32000044 DOI: 10.1016/j.biopha.2020.109884] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2019] [Revised: 01/08/2020] [Accepted: 01/13/2020] [Indexed: 10/25/2022] Open
Abstract
BACKGROUND Osteosarcoma (OS) is a primary malignant bone sarcoma in human worldwide. It has been shown that the level of microRNA-154-5p (miR-154-5p) was downregulated in human OS tissues. However, the mechanisms by which miR-154-5p regulates the proliferation, apoptosis and invasion in OS remain unclear. Thus, the present study aimed to investigate the role of miR-154-5p during the tumorigenesis of OS. METHODS The level of miR-154-5p in human OS tissues was detected by RT-qPCR. In addition, the effects of miR-154-5p on apoptosis and invasion of OS cells were assessed by flow cytometry and transwell assays, respectively. Meanwhile, the dual luciferase reporter system assay was performed to explore the interaction of miR-154-5p and E2F5. RESULTS The level of miR-154-5p was downregulated in OS tissues. Overexpression of miR-154-5p significantly inhibited the proliferation, migration and invasion of MG63 cells. In addition, upregulation of miR-154-5p obviously induced apoptosis in MG63 cells via upregulation of Bax and cleaved caspase 3, and downregulation of Bcl-2. Moreover, luciferase reporter assay identified that E2F5 was the binding target of miR-154-5p. Meanwhile, overexpression of miR-154-5p induced cell cycle arrest in MG63 cells via inhibiting the expressions of E2F5, Cyclin E1 and CDK2. Furthermore, in vivo assays indicated that overexpression of miR-154-5p notably inhibited the tumor growth in an OS xenograft model. CONCLUSION These results indicated that miR-154-5p may function as a potential tumor suppressor in OS. Therefore, miR-154-5p might be a novel therapeutic option for the treatment of OS.

Li S, Zheng K, Pei Y, Wang W, Zhang X. Long noncoding RNA NR2F1-AS1 enhances the malignant properties of osteosarcoma by increasing forkhead box A1 expression via sponging of microRNA-483-3p. Aging (Albany NY) 2019; 11:11609-11623. [PMID: 31801112 PMCID: PMC6932892 DOI: 10.18632/aging.102563] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Accepted: 11/20/2019] [Indexed: 12/31/2022]
Abstract
The long noncoding RNA NR2F1-AS1 has been found to promote the development of hepatocellular carcinoma and endometrial cancer. In this study, we measured NR2F1-AS1 expression in osteosarcoma (OS), determined the involvement of NR2F1-AS1 in the malignant properties of OS, and investigated the underlying mechanisms. NR2F1-AS1 was found to be upregulated in OS tumors and cell lines. The increased NR2F1-AS1 level was closely associated with advanced clinical stage and distant metastasis in patients with OS. Patients with OS in an NR2F1-AS1 high-expression group demonstrated significantly shorter overall survival than did patients in an NR2F1-AS1 low-expression group. NR2F1-AS1 knockdown inhibited OS cell proliferation, migration, and invasion and promoted cell cycle arrest and apoptosis in vitro and slowed tumor growth in vivo. NR2F1-AS1 was found to function as a competing endogenous RNA by directly sponging microRNA-483-3p (miR-483-3p) and upregulating its target oncogene forkhead box A1 (FOXA1). Finally, rescue experiments revealed that knockdown of miR-483-3p and recovery of FOXA1 expression both attenuated the influence of the NR2F1-AS1 knockdown on OS cells. Thus, NR2F1-AS1 plays an oncogenic role in OS through sponging miR-483-3p and thereby upregulating FOXA1, suggesting an additional target for osteosarcoma therapeutics.
