Abstract
MicroRNAs (miRNAs) are a type of non-coding RNA whose dysregulation is frequently associated with the onset and progression of human cancers. miR-142, an ultra-conserved miRNA with both active -3p and -5p mature strands and wide-ranging physiological targets, has been the subject of countless studies over the years. Due to its preferential expression in hematopoietic cells, miR-142 has been found to be associated with numerous types of lymphomas and leukemias. This review elucidates the multifaceted role of miR-142 in human physiology, its influence on hematopoiesis and hematopoietic cells, and its intriguing involvement in exosome-mediated miR-142 transport. Moreover, we offer a comprehensive exploration of the genetic and molecular landscape of the miR-142 genomic locus, highlighting its mutations and dysregulation within hematological malignancies. Finally, we discuss potential avenues for harnessing the therapeutic potential of miR-142 in the context of hematological malignancies.

[PMID: 38129425 PMCID: PMC10739902 DOI: 10.1038/s41598-023-48950-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 12/01/2023] [Indexed: 12/23/2023] Open
Abstract
Clinical studies have found 14-3-3η to be associated with osteoporosis through undefined mechanisms. We aimed to investigate the role of 14-3-3η in osteoporosis and its potential associations with miRNAs. The Gene Expression Omnibus(GEO) and Human Protein Atlas 1 databases were analyzed to examine both the mRNA and protein expression of 14-3-3η in OP. Gene enrichment analyses were performed to explore the underlying mechanism of 14-3-3η based on DAVID. miRWalk was used to predict the associated miRNAs. The statistics were analysed by R software and SPSS software. 14-3-3η was overexpressed and knock down expressed in BMSCs by lentiviral vector transfecting. And BMSCs were induced by hypoxia. qRT-PCR and Western-Blot verified the expression of mRNA and protein. Scratch assay detected the migration of osteocytes. Co-immunoprecipitation and luciferase assay studied the 14-3-3η targeted protein and miRNA. overexpression and knock down of miRNA to verify the relationship of 14-3-3η and target genes. The 14-3-3η mRNA expression level was low in patients with osteoporosis, as corroborated by immunohistochemical staining images. Functional analyses revealed enrichment of the MAPK-associated cascade. 14-3-3η was correlated with MAPK family proteins and five key miRNAs, including mir-142-3p. In addition, 14-3-3η knockdown in BMSCs increased the mRNA and protein expression levels of Hif-α, VEGF, BMP-2, OPN, OST, and Runx2, and enhanced the cells migration ability. Under hypoxic conditions, Hif-α and BMP-2 protein expression levels were upregulated, whereas those of 14-3-3η and MAPK3 were downregulated. Co-immunoprecipitation experiments showed decreased binding of 14-3-3η to MAPK3. 14-3-3η knockdown produced the same results as hypoxia induction. Adding caspase3 inhibitor and knocking down 14-3-3η again prevented MAPK3 cleavage by caspase3 and inhibited BMP-2 expression. Moreover, under hypoxic conditions, miR-142-3P expression was upregulated and luciferase assays revealed 14-3-3η as its target gene. miR-142-3P overexpression decreased mRNA and protein levels of 14-3-3η and MAPK3, while increasing BMP-2 expression. miR-142-3P knockdown reversed these results. BMSC osteogenesis was suppressed by 14-3-3η, whereas miRNA-142-3p promoted it through the inhibition of 14-3-3η.

Abstract
The field of cartilage repair has exponentially been growing over the past decade. Here, we discuss the possibility to achieve satisfactory regeneration of articular cartilage by means of human mesenchymal stem cells (hMSCs) depleted of anti-chondrogenic factors and implanted in the site of injury. Different types of molecules including transcription factors, transcriptional co-regulators, secreted proteins, and microRNAs have recently been identified as negative modulators of chondroprogenitor differentiation and chondrocyte function. We review the current knowledge about these molecules as potential targets for gene knockdown strategies using RNA interference (RNAi) tools that allow the specific suppression of gene function. The critical issues regarding the optimization of the gene silencing approach as well as the delivery strategies are discussed. We anticipate that further development of these techniques will lead to the generation of implantable hMSCs with enhanced potential to regenerate articular cartilage damaged by injury, disease, or aging.

Abstract
Fracture repair is a complex process that involves multiple biological processes requiring spatiotemporal expression of thousands of genes. The molecular regulation of this process is not completely understood. MicroRNAs (miRNAs) regulate gene expression by promoting mRNA degradation or blocking translation. To identify miRNAs expressed during fracture repair, we generated murine bone fractures and isolated miRNA-enriched RNA from intact and post-fracture day (PFD) 1, 3, 5, 7, 11, and 14 femurs. RNA samples were individually hybridized to mouse miRNA microarrays. Results indicated that 959 (51%) miRNAs were absent while 922 (49%) displayed expression in at least one sample. Of the 922 miRNAs, 306 (33.2%) and 374 (40.6%) were up- and down-regulated, respectively, in the calluses in comparison to intact bone. Additionally, 20 (2.2%) miRNAs displayed combined up- and down-regulated expression within the time course and the remaining 222 (24%) miRNAs did not exhibit any changes between calluses and intact bone. Quantitative-PCR validated the expression of several miRNAs. Further, we identified 2048 and 4782 target genes that were unique to the up- and down-regulated miRNAs, respectively. Gene ontology and pathway enrichment analyses indicated relevant biological processes. These data provide the first complete analysis of the miRNA transcriptome during the early phases of fracture repair.

Abstract
The transforming growth factor β (TGFβ) signaling pathway is critical for the promotion and maintenance of the contractile phenotype of vascular smooth muscle cells (VSMCs). Though multiple microRNAs (miRNAs) implicated in the regulation of the VSMC phenotype have been identified, the modulation of miRNAs in the VSMCs by TGFβ signaling has not been fully described. In this study, we identified microRNA-142-3p (miR-142-3p) as a modulator of the VSMC phenotype in response to TGFβ signaling. We show that miR-142-3p is induced upon TGFβ signaling, leading to the repression of a novel target, dedicator of cytokinesis 6 (DOCK6). The downregulation of DOCK6 by miR-142-3p is critical for cell migration. Thus, this study demonstrates that miR-142-3p is a key regulator of the TGFβ-mediated contractile phenotype of VSMCs that acts through inhibiting cell migration through targeting DOCK6.

Abstract
Osteoarthritis (OA) is an age-related disease with poorly understood pathogenesis. Recent studies have demonstrated that miRNA might play a key role in OA initiation and development. We reviewed recent publications and elucidated the connection between miRNA and OA cartilage anabolic and catabolic signals, including four signaling pathways: TGF-β/Smads and BMPs signaling, associated with cartilage anabolism; and MAPK and NF-KB signaling, associated with cartilage catabolism. We also explored the relationships with MMP, ADAMTS and NOS (NitricOxide Synthases) families, as well as with the catabolic cytokines IL-1 and TNF-α. The potential role of miRNAs in biological processes such as cartilage degeneration, chondrocyte proliferation, and differentiation is discussed. Collective evidence indicates that miRNAs play a critical role in cartilage degeneration. These findings will aid in understanding the molecular network that governs articular cartilage homeostasis and in to elucidate the role of miRNA in the pathogenesis of OA.

Abstract
Defects of articular cartilage present a unique clinical challenge due to its poor self-healing capacity and avascular nature. Current surgical treatment options do not ensure consistent regeneration of hyaline cartilage in favor of fibrous tissue. Here, we review the current understanding of the most important biological regulators of chondrogenesis and their interactions, to provide insight into potential applications for cartilage tissue engineering. These include various signaling pathways, including: fibroblast growth factors (FGFs), transforming growth factor β (TGF-β)/bone morphogenic proteins (BMPs), Wnt/β-catenin, Hedgehog, Notch, hypoxia, and angiogenic signaling pathways. Transcriptional and epigenetic regulation of chondrogenesis will also be discussed. Advances in our understanding of these signaling pathways have led to promising advances in cartilage regeneration and tissue engineering.

Abstract
Preclinical Research Bone is a rigid and dynamic organ that undergoes continuous turnover. Bone homeostasis is maintained by osteoclast-mediated bone resorption and osteoblast-mediated bone formation. The interruption of this balance can cause various diseases, including osteoporosis a public health issue due to the rate of hip fracture, the most serious outcome of osteoporosis. The bone loss in osteoporosis results from an increase in bone resorption versus bone formation. Thus, regulation of osteoblast and osteoclast activity is a main focus in the treatment of osteoporosis. MicroRNAs (miRNAs) are a class of single stranded noncoding RNAs consisting of 18-22 nucleotides that have an important role in cell differentiation, cell fate, apoptosis, and pathogenesis in various disease states. The potential therapeutic and biomarker function of miRNAs in treating bone disorders is receiving more attention. The current review summarizes the role of miRNAs in bone function at a cellular level in the context of their therapeutic potential.

Abstract
BACKGROUND Early-onset preeclampsia (EOPET), resulting in intrauterine growth restriction, has serious impact on maternal, perinatal, and neonatal livability worldwide. The current study conducted bioinformatics analyses to screen key genes and microRNAs (miRNAs) involved in EOPET and thus to explore the molecular mechanisms of EOPET. METHODS The microarray data set GSE44711 containing 8 EOPET placentas and 8 gestational age-matched controls was obtained from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were screened and subjected to gene ontology functional enrichment analysis. Then, Human Protein Reference Database was used to construct protein-protein interaction (PPI) network of DEGs. Besides, we predicted EOPET-associated miRNAs and built the miRNA regulatory network. RESULTS A total of 150 DEGs including 26 upregulated and 124 downregulated genes were obtained. Corticotropin releasing hormone (CRH) and vitronectin (VTN) was the most significantly upregulated and downregulated genes, respectively. The DEGs were mainly related to the biological process (BP) of pregnancy, hormone-involved process, and formation of extracellular region. Analysis of PPI network revealed that fibronectin 1(FN1), FBJ murine osteosarcoma viral oncogene homolog (FOS), CD247 molecule (CD247), VTN, and interleukin 2 receptor, beta (IL2RB) were the top 5 DEGs with highest node degree. Furthermore, many EOPET-associated miRNAs were identified and miR-142-3p was the most significant one. Additionally, multiple miRNAs, such as miR-200b/c and miR-27a/b, were predicted to regulate the expression of several key DEGs. CONCLUSION The current study identified several regulators in EOPET, which may contribute to interpret the molecular mechanism of EOPET and develop novel biomarkers and therapeutic targets for EOPET.

Abstract
BACKGROUND The immune therapeutic potential of microRNAs (miRNAs) in the context of tumor-mediated immune suppression has not been previously described for monocyte-derived glioma-associated macrophages, which are the largest infiltrating immune cell population in glioblastomas and facilitate gliomagenesis. METHODS An miRNA microarray was used to compare expression profiles between human glioblastoma-infiltrating macrophages and matched peripheral monocytes. The effects of miR-142-3p on phenotype and function of proinflammatory M1 and immunosuppressive M2 macrophages were determined. The therapeutic effect of miR-142-3p was ascertained in immune-competent C57BL/6J mice harboring intracerebral GL261 gliomas and in genetically engineered Ntv-a mice bearing high-grade gliomas. Student t test was used to evaluate the differences between ex vivo datasets. Survival was analyzed with the log-rank test and tumor sizes with linear mixed models and F test. All statistical tests were two-sided. RESULTS miR-142-3p was the most downregulated miRNA (approximately 4.95-fold) in glioblastoma-infiltrating macrophages. M2 macrophages had lower miR-142-3p expression relative to M1 macrophages (P = .03). Overexpression of miR-142-3p in M2 macrophages induced selective modulation of transforming growth factor beta receptor 1, which led to subsequent preferential apoptosis in the M2 subset (P = .01). In vivo miR-142-3p administration resulted in glioma growth inhibition (P = .03, n = 5) and extended median survival (miR-142-3p-treated C57BL/6J mice vs scramble control: 31 days vs 23.5 days, P = .03, n = 10; miR-142-3p treated Ntv-a mice vs scramble control: 32 days vs 24 days, P = .03, n = 9), with an associated decrease in infiltrating macrophages (R (2) = .303). CONCLUSIONS These data indicate a unique role of miR-142-3p in glioma immunity by modulating M2 macrophages through the transforming growth factor beta signaling pathway.

Abstract
The discovery of cell surface receptors that bind to extracellular matrix (ECM) components marked a new era in biological research. Since then there has been an increasing appreciation of the importance of studying cells in the context of their extracellular environment. Cell behaviour is profoundly affected by the ECM, whose synthesis and turnover must be finely balanced in order to maintain normal function and prevent disease. In the last decade, microRNAs (miRNAs) have emerged as key regulators of ECM gene expression. As new technologies for the identification and validation of miRNA targets continue to be developed, a growing body of data supporting the role of miRNAs in regulating the ECM biology has arisen from a variety of cell and animal models along with clinical studies. However, more recent findings suggest an intriguing interplay between the ECM and miRNAs: not only can miRNAs control the composition of the ECM, but also the ECM can affect the expression of specific miRNAs. Here we discuss how miRNAs contribute to the synthesis, maintenance and remodelling of the ECM during development and disease. Furthermore, we bring to light evidence that points to a role for the ECM in regulating miRNA expression and function.

Abstract
OBJECTIVE This study sought to identify the profile of circulating microRNAs (miRNAs) in type 2 diabetes (T2D) and its response to changes in insulin sensitivity. RESEARCH DESIGN AND METHODS The circulating miRNA profile was assessed in a pilot study of 12 men: 6 with normal glucose tolerance (NGT) and 6 T2D patients. The association of 10 circulating miRNAs with T2D was cross-sectionally validated in an extended sample of 45 NGT vs. 48 T2D subjects (65 nonobese and 28 obese men) and longitudinally in 35 T2D patients who were recruited in a randomized, double-blinded, and placebo-controlled 3-month trial of metformin treatment. Circulating miRNAs were also measured in seven healthy volunteers before and after a 6-h hyperinsulinemic-euglycemic clamp and insulin plus intralipid/heparin infusion. RESULTS Cross-sectional studies disclosed a marked increase of miR-140-5p, miR-142-3p, and miR-222 and decreased miR-423-5p, miR-125b, miR-192, miR-195, miR-130b, miR-532-5p, and miR-126 in T2D patients. Multiple linear regression analyses revealed that miR-140-5p and miR-423-5p contributed independently to explain 49.5% (P < 0.0001) of fasting glucose variance after controlling for confounders. A discriminant function of four miRNAs (miR-140-5p, miR-423-5p, miR-195, and miR-126) was specific for T2D with an accuracy of 89.2% (P < 0.0001). Metformin (but not placebo) led to significant changes in circulating miR-192 (49.5%; P = 0.022), miR-140-5p (-15.8%; P = 0.004), and miR-222 (-47.2%; P = 0.03), in parallel to decreased fasting glucose and HbA1c. Furthermore, while insulin infusion during clamp decreased miR-222 (-62%; P = 0.002), the intralipid/heparin mixture increased circulating miR-222 (163%; P = 0.015) and miR-140-5p (67.5%; P = 0.05). CONCLUSIONS This study depicts the close association between variations in circulating miRNAs and T2D and their potential relevance in insulin sensitivity.

Abstract
Non-coding RNAs have been less studied in cartilage development and destruction regulated by sophisticated molecular events despite their considerable theranostic potential. In this study, we identified significant down-regulation of mR-101 and up-regulation of lncRNA, HOTTIP in the processes of endochondral ossification and osteoarthritic progression. In wing mesenchymal cells, up-expression of miR-101 by TGF-β3 treatment is targeting DNMT-3B and thereby altered the methylation of integrin-α1 addressed as a positive regulator of endochondral ossification in this study. In like manner, down-regulation of miR-101 also coordinately up-regulated DNMT-3B, down-regulated integrin-α1, and resulted in cartilage destruction. In an OA animal model, introduction of lentiviruses that encoded miR-101 or integrin-α1 successfully reduced cartilage destruction. In like manner, long non-coding RNA (lncRNA), HOTTIP, a known regulator for HoxA genes, was highly up-regulated and concurrent down-regulation of HoxA13 displayed the suppression of integrin-α1 in OA chondrocytes. In conclusion, two non-coding RNAs, miR-101 and HOTTIP regulate cartilage development and destruction by modulating integrin-α1 either epigenetically by DNMT-3B or transcriptionally by HoxA13 and data further suggest that these non-coding RNAs could be a potent predictive biomarker for OA as well as a therapeutic target for preventing cartilage-related diseases.

Abstract
Cartilage has limited repair and regeneration capacity, thus damage of cartilage often results in its dysfunction and even chronic diseases like osteoarthritis (OA). Chondrogenesis induced by tissue-engineering methods is essential to treating cartilage-related diseases. MicroRNAs (miRNAs) are a class of small non-coding single-stranded RNAs which exert their biological effects by binding to the target messenger RNAs (mRNAs), resulting in decay or translation suppression of target mRNAs. There are emerging evidence indicating that miRNAs may play important roles in regulating both prenatal and postnatal chondrogenesis. During embryonic skeletal development, prenatal chondrogenesis is thought to be a precondition for formation of cartilage in developing limbs. Plenty of studies on different types of stem cells have undoubtedly proven their capacity of differentiating into chondrocytes. MiRNAs are found to comprehensively modulate these processes by establishing an interaction network with target genes, transcription factors and cytokines et al. In addition, translational application of miRNA technology has also been explored. In this review, we focus on the up-dated progress on regulatory mechanisms of miRNAs in prenatal and postnatal chondrogenesis. In addition, several miRNA target genes and roles of miRNAs in cartilage-related diseases are also discussed. This will contribute to studies of chondrogenesis mechanisms and development of new treating methods.

MicroRNA-145 targets the metalloprotease ADAM17 and is suppressed in renal cell carcinoma patients. Neoplasia 2013; 15:218-30.

Abstract
A disintegrin and metalloproteinase 17 (ADAM17) is a metalloprotease that is overexpressed in many cancer types, including renal cancers. However, the regulatory mechanisms of ADAM17 in cancer development and progression are poorly understood. In the present work, we provide evidence using overexpression and inhibition of microRNA 145 (miR-145) that miR-145 negatively regulates ADAM17 expression. Furthermore, we show that ADAM17 negatively regulates miR-145 through tumor necrosis factor-α, resulting in a reciprocal negative feedback loop. In this study, the expression of ADAM17 and miR-145 correlated negatively in renal cancer tumor tissues and cell lines, suggesting an important regulatory mechanism. Additionally, we showed that the regulation of ADAM17 is partly involved in the effects of miR-145 on proliferation and migration, whereas no involvement in chemosensitivity was observed. Importantly, in the healthy kidney, miR-145 was detected in different cell types including tubular cells, which are considered the origin of renal cancer. In renal cancer cell lines, miR-145 expression was strongly suppressed by methylation. In summary, miR-145 is downregulated in renal cancer patients, which leads to the up-regulation of ADAM17 in renal cancer. Importantly, miR-145 and ADAM17 are regulated in a reciprocal negative feedback loop.

Abstract
The mixed-lineage leukemia (MLL)-AF4 fusion protein encoded by the chromosomal translocation t(4;11) predicts a poorer prognosis in acute lymphoblastic leukemia (ALL) than in other MLL-associated leukemias. However, the detailed mechanism underlying regulation of MLL-AF4 expression remains largely unknown. In this study, we showed that microRNA (miR)-142-3p was significantly downregulated in ALL patients expressing MLL-AF4. Upregulation of miR-142-3p decreased MLL-AF4 expression in the RS4;11 leukemic cell line, which suggests that MLL-AF4 is a direct target of miR-142-3p. Ectopic expression of miR-142-3p remarkably suppressed cell proliferation and induced apoptosis in RS4;11 cells expressing the MLL-AF4 fusion protein. We also found that exogenous expression of miR-142-3p strongly reduced the expression of MLL-AF4 target genes such as homeobox A (HOXA)9, HOXA7, and HOXA10 in RS4;11 cells. Taken together, our results indicate that miR-142-3p functions as a growth suppressor in MLL-AF4(+) ALL, and its suppressive effects are mediated primarily through repression of MLL-AF4 expression.

Abstract
MicroRNAs (miRNAs) are a class of ~22 nucleotide-long small noncoding RNAs that target mRNAs for translational repression or degradation. miRNAs target mRNAs by base-pairing with the 3'-untranslated regions (3'-UTRs) of mRNAs. miRNAs are present in various species, from animals to plants. In this review, we summarize the identification, expression, and function of miRNAs in four important farm animal species: cattle, chicken, pig and sheep. In each of these species, hundreds of miRNAs have been identified through homology search, small RNA cloning and next generation sequencing. Real-time RT-PCR and microarray experiments reveal that many miRNAs are expressed in a tissue-specific or spatiotemporal-specific manner in farm animals. Limited functional studies suggest that miRNAs have important roles in muscle development and hypertrophy, adipose tissue growth, oocyte maturation and early embryonic development in farm animals. Increasing evidence suggests that single-nucleotide polymorphisms in miRNA target sites or miRNA gene promoters may contribute to variation in production or health traits in farm animals.

Abstract
BACKGROUND Genomic studies have yielded important insights into the pathogenesis of obesity. Circulating microRNAs (miRNAs) are valuable biomarkers of systemic diseases and potential therapeutic targets. We sought to define the circulating pattern of miRNAs in obesity and examine changes after weight loss. METHODS We assessed the genomewide circulating miRNA profile cross-sectionally in 32 men and after surgery-induced weight loss in 6 morbidly obese patients. The most relevant miRNAs were cross-sectionally validated in 80 men and longitudinally in 22 patients (after surgery-induced weight loss). We evaluated the effects of diet-induced weight loss in 9 obese patients. Thirty-six circulating miRNAs were associated with anthropometric variables in the initial sample. RESULTS In the validation study, morbidly obese patients showed a marked increase of miR-140-5p, miR-142-3p (both P < 0.0001), and miR-222 (P = 0.0002) and decreased levels of miR-532-5p, miR-125b, miR-130b, miR-221, miR-15a, miR-423-5p, and miR-520c-3p (P < 0.0001 for all). Interestingly, in silico targets leukemia inhibitory factor receptor (LIFR) and transforming growth factor receptor (TGFR) of miR-140-5p, miR-142-3p, miR-15a, and miR-520c-3p circulated in association with their corresponding miRNAs. Moreover, a discriminant function of 3 miRNAs (miR-15a, miR-520c-3p, and miR-423-5p) was specific for morbid obesity, with an accuracy of 93.5%. Surgery-induced (but not diet-induced) weight loss led to a marked decrease of miR-140-5p, miR-122, miR-193a-5p, and miR-16-1 and upregulation of miR-221 and miR-199a-3p (P < 0.0001 for all). CONCLUSIONS Circulating miRNAs are deregulated in severe obesity. Weight loss-induced changes in this profile and the study of in silico targets support this observation and suggest a potential mechanistic relevance.

Abstract
Canonical Wnt signaling is critical for the control of osteoblast differentiation in human mesenchymal stem cells. MicroRNAs (miRs) are essential regulators of cell differentiation by post‑transcriptional regulation of target gene expression. The aim of the present study was to investigate the molecular mechanism by which miR‑142‑3p promotes osteoblastic differentiation using the human fetal osteoblastic 1.19 (hFOB1.19), real-time PCR and western blot analysis. Results showed an increased expression of miR‑142‑3p during osteoblast differentiation in the mesenchymal precursor cell line, hFOB1.19. In addition, the ectopic over-expression of miR‑142‑3p promoted hFOB1.19 differentiation, whereas the inhibition of miR‑142‑3p repressed differentiation. The expression of miR‑142‑3p was positively correlated with β‑catenin, an important protein in Wnt signaling. The adenomatous polyposis coli (APC) gene was a direct target of miR‑142‑3p, whereby miR‑142‑3p promoted Wnt signaling through inhibition of APC, leading to accumulation and nuclear translocation of β‑catenin. Therefore, miR‑142‑3p may be an essential mediator of osteoblast differentiation and a new therapeutic strategy for osteogenesis disorders.

Abstract
Endochondral bone formation requires a complex interplay among immature mesenchymal progenitor cells to form the cartilaginous anlagen, involving migration, aggregation and condensation. Even though condensation of chondrogenic progenitors is an essential step in this process, the mechanism(s) by which this occurs has not been well studied. Here, we investigated the involvement of microRNAs (miRNAs) in this process and found that the expression of miR-375 decreased upon chondrogenic differentiation of limb mesenchymal cells. Blockade of miR-375 via peptide nucleic acid (PNA)-based antisense oligonucleotides (ASOs) increased the migration of chondrogenic progenitors, the formation of precartilage condensations and the expression level of cadherin-7. Furthermore, miR-375 was necessary and sufficient to down-regulate cell migration through negative regulation of cadherin-7 by the direct interaction with 3' UTR of cadherin-7. In addition, miR-375 is also involved in the cell migration and precartilage condensation mediated by p38MAPK, a positive signaling in the chondrogenic differentiation. Collectively, our results suggest that miR-375 negatively modulates cell migration and subsequent precartilage condensation by targeting cadherin-7.

Abstract
The activin/transforming growth factor-β (TGF-β) pathway plays an important role in tumorigenesis either by its tumor suppressor or tumor promoting effect. Loss of members of the TGF-β signaling by somatic mutations or epigenetic events, such as DNA methylation or regulation by microRNA (miRNA), may affect the signaling process. Most members of the TGF-β pathway are known to be targeted by one or more miRNAs. In addition, the biogenesis of miRNAs is also regulated by TGF-β both directly and through SMADs. Based on these interactions, it appears that autoregulatory feedback loops between TGF-β and miRNAs influence the fate of tumor cells. Our aim is to review the crosstalk between TGF-β signaling and the miRNA machinery to highlight potential novel therapeutic targets.
