Abstract
Chemoresistance is a common and thorny problem in the treatment of osteosarcoma (OS), which obstructs the response of relapse or metastasis of OS to chemotherapy and leads to the unfavorable prognosis of OS patients. Cyclin L1 (CCNL1) is a non-canonical cyclin that plays an important role in the regulation of tumor cell proliferation and lymph node metastasis. In this work, we explored the impact of CCNL1 expression levels on proliferation, migration, and Adriamycin (ADM) resistance in OS and related mechanisms. We found that CCNL1 expression levels were significantly associated with clinical prognosis of patients with OS and CCNL1 could promote OS proliferation and migration. In addition, we also revealed that cellular CCNL1 was significantly increased in ADM-resistant OS cells and promoted ADM resistance. The PI3K/AKT-mTOR pathway is involved in CCNL1-mediated ADM resistance in OS. In summary, CCNL1 is involved in the progression of ADM resistance and OS through the PI3K/AKT-mTOR pathway, which will provide a new clue to the mechanism of ADM resistance and a potential target for the treatment of ADM-resistant OS.

Zeng X, Hu Z, Shen Y, Wei X, Gan J, Liu Z. MiR-5195-3p functions as a tumor suppressor in prostate cancer via targeting CCNL1. Cell Mol Biol Lett 2022; 27:25. [PMID: 35260070 PMCID: PMC8905902 DOI: 10.1186/s11658-022-00326-8] [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: 12/14/2021] [Accepted: 02/22/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Accumulating evidence indicates that miR-5195-3p exerts tumor-suppressive roles in several tumors. However, the clinical significance and biological function of miR-5195-3p in prostate cancer (PCa) have not been reported yet. METHODS The expression levels of miR-5195-3p and Cyclin L1 (CCNL1) were determined using quantitative real-time PCR in clinical specimens and cell lines. The clinical significance of miR-5195-3p in patients with PCa was evaluated using Kaplan-Meier survival analysis and Cox regression models. Cell proliferation and cell cycle distribution were measured by CCK-8 assay and flow cytometry, respectively. The association between miR-5195-3p and CCNL1 was analyzed by luciferase reporter assay. RESULTS MiR-5195-3p expression levels were significantly downregulated in 69 paired PCa tissues compared with matched adjacent normal tissues. The decreased miR-5195-3p expression was associated with Gleason score and TNM stage, as well as worse survival prognosis. The in vitro experiments showed that miR-5195-3p overexpression suppressed the proliferation and cell cycle G1/S transition in PC-3 and DU145 cells. Elevated miR-5195-3p abundance obviously impaired tumor formation in vivo using PC-3 xenografts. Mechanistically, CCNL1 was a direct target of miR-5195-3p in PCa cells, which was inversely correlated with miR-5195-3p in PCa tissues. Importantly, CCNL1 knockdown imitated, while overexpression reversed, the effects of miR-5195-3p overexpression on PCa cell proliferation and cell cycle G1/S transition. CONCLUSIONS Our data suggest that miR-5195-3p functions as a tumor suppressor by targeting CCNL1 in PCa.

Abstract
Ewing's sarcoma (ES) is a pediatric sarcoma caused by a chromosomal translocation. Unlike in most cancers, the genomes of ES patients are very stable. The translocation product of the EWS-FLI1 fusion is most often the predominant genetic driver of oncogenesis, and it is pertinent to explore the role of epigenetic alterations in the onset and progression of ES. Several types of noncoding RNAs, primarily microRNAs and long noncoding RNAs, are key epigenetic regulators that have been shown to play critical roles in various cancers. The functions of these epigenetic regulators are just beginning to be appreciated in ES. Here, we performed a comprehensive literature review to identify these noncoding RNAs. We identified clinically relevant tumor suppressor microRNAs, tumor promoter microRNAs and long noncoding RNAs. We then explored the known interplay between different classes of noncoding RNAs and described the currently unmet need for expanding the noncoding RNA repertoire of ES. We concluded the review with a discussion of epigenetic regulation of ES via regulatory noncoding RNAs. These noncoding RNAs provide new avenues of exploration to develop better therapeutics and identify novel biomarkers.

Abstract
Mesenchymal stem cells (MSCs) have been identified in many adult tissues. MSCs can regenerate through cell division or differentiate into adipocytes, osteoblasts and chondrocytes. As a result, MSCs have become an important source of cells in tissue engineering and regenerative medicine for bone tissue and cartilage. Several epigenetic factors are believed to play a role in MSCs differentiation. Among these, microRNA (miRNA) regulation is involved in the fine modulation of gene expression during osteogenic/chondrogenic differentiation. It has been reported that miRNAs are involved in bone homeostasis by modulating osteoblast gene expression. In addition, countless evidence has demonstrated that miRNAs dysregulation is involved in the development of osteoporosis and bone fractures. The deregulation of miRNAs expression has also been associated with several malignancies including bone cancer. In this context, bone-associated circulating miRNAs may be useful biomarkers for determining the predisposition, onset and development of osteoporosis, as well as in clinical applications to improve the diagnosis, follow-up and treatment of cancer and metastases. Overall, this review will provide an overview of how miRNAs activities participate in osteogenic/chondrogenic differentiation, while addressing the role of miRNA regulatory effects on target genes. Finally, the role of miRNAs in pathologies and therapies will be presented.

Abstract
OBJECTIVE This research aims to investigate the relationship between the expression of microRNA-199b-5p (miR-199b-5p) and soluble human leukocyte antigen G (sHLA-G) in thyroid cancer tissues and its clinicopathological characteristics, as well as its impact on prognosis. METHODS Frozen tissues and serum from 85 patients with thyroid cancer, 27 with thyroid adenoma, 19 with Hashimoto's thyroiditis and 14 with nodular goiter from February 2014 to March 2016 were sampled. The miR-199b-5pmRNA expression in tissues was analyzed by real-time quantitative PCR. Serum HLA-G expression was detected by ELISA, and the relationship between s HLA-G expression and clinicopathological characteristics of thyroid cancer was analyzed. The relationship between 1- and 3-year survival rates of all patients and the expression of both detection indexes was observed. RESULTS Compared with normal thyroid specimens, nodular goiter, Hashimoto's thyroiditis, thyroid adenoma and thyroid cancer patients, the relative expression of miR-199b-5pmRNA in thyroid cancer tissues was the lowest, while that of s HLA-G was the highest in serum of patients (P < 0.05). The levels of miR-199b-5pmRNA and serum s HLA-G in tumor tissues were correlated with clinical pathological features such as tumor size, differentiation degree, capsule invasion, lymph node metastasis, etc. (all P < 0.05). The expression of miR-199b-5pmRNA and s HLA-G were negatively correlated. ROC curve identified that miR-199b-5pmRNA and HLA-g had obvious diagnostic value for thyroid cancer patients. Kaplan-Meier survival analysis manifested that the 1- and 3-year survival rates of the miR-199b-5p low expression group in thyroid cancer tissues were lower than the miR-199b-5p high expression group, and the rates of the s HLA-G low expression group were higher than the s HLA-G high expression group. CONCLUSION The miR-199b-5p expression in thyroid cancer tissues and HLA-g in serum were related to tumor size, differentiation degree, capsular invasion, lymph node metastasis and other characteristics. MiR-199b-5p may jointly affect the progression of thyroid cancer with s HLA-G.

Abstract
The present study aimed to investigate the expression of microRNAs (miRNAs/miRs) and inflammatory factors in patients with immunoglobulin-sensitive and IVIG-insensitive incomplete Kawasaki disease (KD). One hundred and eighty-five patients with incomplete KD were included as the study group (KD group), and 182 patients with respiratory infection as the control group. Neutrophil to lymphocyte ratio (NLR), C-reactive protein (CRP) levels, alanine aminotransferase (ALT), aspartate aminotransferase (AST), white blood cell count (WBC), hemoglobin level (Hb), platelet count (PLT) and T cell subsets (CD3+, CD3+ CD4+) were compared. Patients in the KD group received aspirin (30 mg/kg orally daily) and gamma globulin (IVIG, 1 g/kg intravenously daily). According to the sensitivity to IVIG, patients were divided into IVIG-sensitive group and IVIG-insensitive KD group. The relative expression levels of miRNA-21, miRNA-145, miRNA-155 and miRNA-199b-5p in the serum were detected by RT-qPCR. Serum TNF-α, IL-6 and IL-1β levels were assessed using ELISA. Before treatment, the neutrophil to lymphocyte ratio (NLR), levels C-reactive protein, and leukocytes in the KD group were significantly higher compared with the control group (P<0.05). After medical intervention, the relative expression of miRNA-21, miRNA-145 and miRNA-155 in the serum of patients in IVIG-sensitive and IVIG-insensitive KD groups were increased when compared with these levels in the control group (P<0.05). Meanwhile, the relative expression of miRNA-199b-5p was decreased (P<0.05). Compared with the IVIG-sensitive KD group, the relative expression levels of miRNA-145 and miRNA-155 were increased in the serum of patients in the IVIG-insensitive KD group (P<0.05). Compared with the control group, the levels of TNF-α, IL-6 and IL-1β were increased in the serum of patients in the IVIG-sensitive and IVIG-insensitive KD groups (P<0.05). Compared with the IVIG-sensitive KD group, the serum levels of TNF-α and IL-6 were increased in patients of the IVIG-insensitive KD group (P<0.05). Except for NLR and CRP, there were differences in the expression of peripheral blood miRNA-145, miRNA-155 and serum TNF-α and IL-6 in patients with immunoglobulin-sensitive and -insensitive incomplete KD.

Body temperature-dependent microRNA expression analysis in rats: rno-miR-374-5p regulates apoptosis in skeletal muscle cells via Mex3B under hypothermia. Sci Rep 2020; 10:15432.

Abstract
Forensic diagnosis of fatal hypothermia is considered difficult because there are no specific findings. Accordingly, exploration of novel fatal hypothermia-specific findings is important. To elucidate the molecular mechanism of homeostasis in hypothermia and identify novel molecular markers to inform the diagnosis of fatal hypothermia, we focused on microRNA expression in skeletal muscle, which plays a role in cold-induced thermogenesis in mammals. We generated rat models of mild, moderate, and severe hypothermia, and performed body temperature-dependent microRNA expression analysis of the iliopsoas muscle using microarray and quantitative real-time PCR (qRT-PCR). The results show that rno-miR-374-5p expression was significantly induced only by severe hypothermia. Luciferase reporter assay and qRT-PCR results indicated that Mex3B expression was regulated by rno-miR-374-5p and decreased with decreasing body temperature. Gene ontology analysis indicated the involvement of Mex3B in positive regulation of GTPase activity. siRNA analysis showed that Mex3B directly or indirectly regulated Kras expression in vitro, and significantly changed the expression of apoptosis-related genes and proteins. Collectively, these results indicate that rno-miR-374-5p was activated by a decrease in body temperature, whereby it contributed to cell survival by suppressing Mex3B and activating or inactivating Kras. Thus, rno-miR-374-5p is a potential supporting marker for the diagnosis of fatal hypothermia.

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
Ossification of the ligamentum flavum (OLF) is a pathology almost only reported in East Asian countries. The leading cause of OLF is thoracic spinal canal stenosis and myelopathy. In this study, the role of miR-199b-5p and jagged 1 (JAG1) in primary ligamentum flavum cell osteogenesis was examined. MiR-199b-5p was found to be down-regulated during osteogenic differentiation in ligamentum flavum cells, while miR-199b-5p overexpression inhibited osteogenic differentiation. In addition, JAG1 was found to be up-regulated during osteogenic differentiation in ligamentum flavum cells, while JAG1 knockdown via RNA interference caused an inhibition of Notch signalling and osteogenic differentiation. Moreover, target prediction analysis and dual luciferase reporter assays supported the notion that JAG1 was a direct target of miR-199b-5p, with miR-199b-5p found to down-regulate both JAG1 and Notch. Further, JAG1 knockdown was demonstrated to block the effect of miR-199b-5p inhibition. These findings imply that miR-199b-5p performs an inhibitory role in osteogenic differentiation in ligamentum flavum cells by potentially targeting JAG1 and influencing the Notch signalling pathway.

Abstract
Sarcomas have traditionally been classified according to their chromosomal alterations regardless of whether they accompany simple or complex genetic changes. Ewing sarcoma, a classic small round cell bone tumor, is a well-known mesenchymal malignancy that results from simple sarcoma-specific genetic alterations. The genetic alterations are translocations between genes of the TET/FET family (TLS/FUS, EWSR1, and TAF15) and genes of the E26 transformation-specific (ETS) family. In this review, we intend to summarize a chronicle of molecular findings of Ewing sarcoma including recent advances and explain resultant molecular pathogenesis.
