Characterization of the Secretome from Spheroids of Adipose-Derived Stem Cells (SASCs) and Its Potential for Tissue Regeneration. Biomedicines 2024; 12:1842. [PMID: 39200306 PMCID: PMC11351933 DOI: 10.3390/biomedicines12081842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2024] [Revised: 08/02/2024] [Accepted: 08/08/2024] [Indexed: 09/02/2024] Open
Abstract
INTRODUCTION Spheroids are spherical aggregates of cells that mimic the three-dimensional (3D) architecture of tissues more closely than traditional two dimensional (2D) cultures. Spheroids of adipose stem cells (SASCs) show special features such as high multilineage differentiation potential and immunomodulatory activity. These properties have been attributed to their secreted factors, such as cytokines and growth factors. Moreover, a key role is played by the extracellular vesicles (EVs), which lead a heterogeneous cargo of proteins, mRNAs, and small RNAs that interfere with the pathways of the recipient cells. PURPOSE The aim of this work was to characterize the composition of the secretome and exosome from SASCs and evaluate their regenerative potential. MATERIALS AND METHODS SASCs were extracted from adipose samples of healthy individuals after signing informed consent. The exosomes were isolated and characterized by Dinamic Light Scattering (DLS), Scanning Electron Microscopy (SEM), and Western blotting analyses. The expression of mRNAs and miRNAs were evaluated through real-time PCR. Lastly, a wound-healing assay was performed to investigate their regenerative potential on different cell cultures. RESULTS The SASCs' exosomes showed an up-regulation of NANOG and SOX2 mRNAs, typical of stemness maintenance, as well as miR126 and miR146a, related to angiogenic and osteogenic processes. Moreover, the exosomes showed a regenerative effect. CONCLUSIONS The SASCs' secretome carried paracrine signals involved in stemness maintenance, pro-angiogenic and pro-osteogenic differentiation, immune system regulation, and regeneration.

Bone 2023; 176:116883. [PMID: 37597797 DOI: 10.1016/j.bone.2023.116883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 08/21/2023]
Abstract
Heterotopic ossification (HO) means the formation of bone in muscles and soft tissues, such as ligaments or tendons. HO could have a genetic history or develop after a traumatic event, as a result of muscle injury, fractures, burns, surgery, or neurological disorders. Many lines of evidence suggest that the formation of HO is related to the pathological differentiation of stem or progenitor cells present within soft tissues or mobilized from the bone marrow. The cells responsible for the initiation and progression of HO are generally called HO precursor cells. The exact mechanisms behind the development of HO are not fully understood. However, several factors have been identified as potential contributors. For example, local tissue injury and inflammation disturb soft tissue homeostasis. Inflammatory cells release growth factors and cytokines that promote osteogenic or chondrogenic differentiation of HO precursor cells. The bone morphogenetic protein (BMP) is one of the main factors involved in the development of HO. In this study, next-generation sequencing (NGS) and RT-qPCR were performed to analyze the differences in mRNA, miRNA, and lncRNA expression profiles between muscles, control bone samples, and HO samples coming from patients who underwent total hip replacement (THR). As a result, crucial changes in the level of gene expression between HO and healthy tissues were identified. The bioinformatic analysis allowed to describe the processes most severely impacted, as well as genes which level differed the most significantly between HO and control samples. Our analysis showed that the level of transcripts involved in leukocyte migration, differentiation, and activation, as well as markers of chronic inflammatory diseases, that is, miR-148, increased in HO, as compared to muscle. Furthermore, the levels of miR-195 and miR-143, which are involved in angiogenesis, were up-regulated in HO, as compared to bone. Thus, we suggested that inflammation and angiogenesis play an important role in HO formation. Importantly, we noticed that HO is characterized by a higher level of TLR3 expression, compared to muscle and bone. Thus, we suggest that infection may also be a risk factor in HO development. Furthermore, an increased level of transcripts coding proteins involved in osteogenesis and signaling pathways, such as ALPL, SP7, BGLAP, BMP8A, BMP8B, SMPD3 was noticed in HO, as compared to muscles. Interestingly, miR-99b, miR-146, miR-204, and LINC00320 were up-regulated in HO, comparing to muscles and bone. Therefore, we suggested that these molecules could be important biomarkers of HO formation and a potential target for therapies.

Abstract
BACKGROUND A number of studies have proposed that lncRNA XIST plays a role in the development and chemosensitivity of NSCLC. Besides, XIST may become a potential therapeutic target for NSCLC patients. The aim of this review is to reveal the biological functions and exact mechanisms of XIST in NSCLC. METHODS In this review, relevant researches involving the relationship between XIST and NSCLC are collected through systematic retrieval of PubMed. RESULTS XIST is an oncogene in NSCLC and is abnormally upregulated in NSCLC tissues. Considerable evidence has shown that XIST plays a critical role in the proliferation, invasion, migration, apoptosis and chemosensitivity of NSCLC cells. XIST mainly functions as a ceRNA in the NSCLC process, while XIST also functions at transcriptional levels. CONCLUSION LncRNA XIST has the potential to become a novel biomolecular marker of NSCLC and a therapeutic target for NSCLC.

Biochem Biophys Rep 2021; 25:100920. [PMID: 33553686 PMCID: PMC7859171 DOI: 10.1016/j.bbrep.2021.100920] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 01/08/2021] [Accepted: 01/12/2021] [Indexed: 12/17/2022] Open
Abstract
In order to understand the role of the p53 tumor suppressor gene in microRNA expression during osteoblast differentiation, we used a screen to identify microRNAs that were altered in a p53-dependent manner. MicroRNAs from MC3T3-E1 preosteoblasts were isolated from day 0 (undifferentiated) and day 4 (differentiating) and compared to a p53 deficient MC3T3-E1 line treated similarly. Overall, one fourth of all the microRNAs tested showed a reduction of 0.6 fold, and a similar number of them were increased 1.7 fold with differentiation. P53 deficiency caused 40% reduction in expression of microRNAs in differentiating cells, while a small percent (0.03%) showed an increase. Changes in microRNAs were validated using real-time PCR and two microRNAs were selected for further analysis (miR-34b and miR-140). These two microRNAs were increased significantly during differentiation but showed a dramatic reduction in expression in a p53 deficient state. Stable expression of miR-34b and miR-140 in MC3T3-E1 cells resulted in decreases in cell proliferation rates when compared to control cells. There was a 4-fold increase in p53 levels with miR-34b expression and a less dramatic increase with miR-140. Putative target binding sites for bone specific transcription factors, Runx2 and Osterix, were found for miR-34b, while Runx2, beta catenin and type 1 collagen were found to be miR-140 targets. Western blot analyses and functional assays for the transcription factors Runx2, Osterix and Beta-catenin confirmed microRNA specific interactions. These studies provide evidence that p53 mediated regulation of osteoblast differentiation can also occur through specific microRNAs such as miR-34b and miR-140 that also directly target important bone specific genes. The p53 tumor suppressor gene regulates microRNA expression during in vitro osteoblast differentiation. miR34b and miR140 targets include several bone specific markers such as runx2, beta catenin, type 1 collagen and osterix. miR34b and miR140 overexpression inhibits osteoblast cell proliferation.

MicroRNAs from Extracellular Vesicles Secreted by Bovine Embryos as Early Biomarkers of Developmental Competence. Int J Mol Sci 2020; 21:ijms21238888. [PMID: 33255183 PMCID: PMC7727673 DOI: 10.3390/ijms21238888] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 11/12/2020] [Accepted: 11/17/2020] [Indexed: 12/17/2022] Open
Abstract
During early development, embryos secrete extracellular vesicles (EVs) that participate in embryo–maternal communication. Among other molecules, EVs carry microRNAs (miRNAs) that interfere with gene expression in target cells; miRNAs participate in embryo–maternal communication. Embryo selection based on secreted miRNAs may have an impact on bovine breeding programs. This research aimed to evaluate the size, concentration, and miRNA content of EVs secreted by bovine embryos with different developmental potential, during the compaction period (days 3.5–5). Individual culture media from in vitro–produced embryos were collected at day 5, while embryos were further cultured and classified at day 7, as G1 (conditioned-culture media by embryos arrested in the 8–16-cells stage) and G2 (conditioned-culture media by embryos that reached blastocyst stages at day 7). Collected nanoparticles from embryo conditioned culture media were cataloged as EVs by their morphology and the presence of classical molecular markers. Size and concentration of EVs from G1 were higher than EVs secreted by G2. We identified 95 miRNAs; bta-miR-103, bta-miR-502a, bta-miR-100, and bta-miR-1 were upregulated in G1, whereas bta-miR-92a, bta-miR-140, bta-miR-2285a, and bta-miR-222 were downregulated. The most significant upregulated pathways were fatty acid biosynthesis and metabolism, lysine degradation, gap junction, and signaling pathways regulating pluripotency of stem cells. The characteristics of EVs secreted by bovine embryos during the compaction period vary according to embryo competence. Embryos that reach the blastocyst stage secrete fewer and smaller vesicles. Furthermore, the loading of specific miRNAs into the EVs depends on embryo developmental competence.

Abstract
BACKGROUND MicroRNA-206 (miR-206) inhibits cell proliferation, invasion and migration in a variety of tumors, but the prognostic value of its Esophageal Cancer (EC) remains unclear. OBJECTIVE To study the role of miR-206 in EC. METHODS The datasets of RNA-Seq, miRNA-Seq, methylation, copy number variation (CNV), and clinical follow-up information were download from The Cancer Genome Atlas (TCGA). After integration and standardization, the prognostic value and potential function of miR-206 were analyzed. The important roles of miR-206 expression in EC genetic and epigenetic mechanisms were analyzed by RNA-Seq, miRNA-Seq, and methylation data. The potential mechanism of CNV in different miR-206 expression groups was analyzed using GISTIC. RESULTS High expression of miR-206 was associated with poor outcome of EC (OS: p=0.005, AUC=0.69, N=178). Transforming growth factor β (TGF-β) signaling pathway, Wnt signaling pathway, mitogen-activated protein kinases (MAPK) signaling pathway, mammalian target of rapamycin (mTOR) signaling pathway were inhibited in high expression group. the aberrant methylation sites in the high and low expression groups were mainly distributed in the promoter region containing CpG islands, and there were different copy number patterns in the H and L samples, and the genes in the differential copy number were mainly enriched in cancer-related pathways, such as thyroid cancer, central carbon metabolism. CONCLUSION This study explored the unique genomic and epigenetic landscape associated with the expression of miR-206, provided evidence of mir-206 as a prognostic biomarker or a potential therapeutic target for EC patients.

Abstract
Renal tubulointerstitial fibrosis is usually the final outcome of various end-stage renal diseases. Recent studies have reported that microRNAs (miRNAs) play an important role in renal fibrosis. However, the biological function of microRNAs in renal fibrosis is complicated and remains unclear. In this study, our results show that miR-140-5p expression is significantly down-regulated in mice with unilateral ureteral obstruction and human proximal tubule epithelial cells (HK2) treated with TGF-β1. The knockdown of miR-140-5p upregulates the expression levels of collagen I, collagen IV, and α-SMA, decreases E-cadherin expression, and increases Smad-2/3 phosphorylation. In contrast, the overexpression of miR-140-5p decreases the expression levels of collagen I, collagen IV, and α-SMA, enhances E-cadherin expression, and inhibits the phosphorylation of Smad-2/3 in HK2 cells treated with TGF-β1. The dual-luciferase reporter assay revealed that TGFBR1 is a direct target gene of miR-140-5p. The enforced expression of miR-140-5p significantly inhibited the expression of TGFBR1 in HK2 cells. Furthermore, the knockdown of TGFBR1 has a similar effect of miR-140-5p overexpression on blocking the TGF-β1/smad signal pathway activation. In contrast, the overexpression of TGFBR1 reverses the effect of miR-140-5p inhibition on the activation of the TGF-β1/smad signal pathway. This study demonstrates that miR-140-5p regulates the TGF-β1/smad signaling pathway by suppressing the expression of TGFBR1. Therefore, miR-140-5p may have a therapeutic potential for preventing fibrotic kidney diseases through inhibiting the TGF-β1/Smad signaling pathway by directly targeting TGFBR1.

Abstract
OBJECTIVE MiR-140 and miR-196a were known to be correlated with cancer diagnosis and prognosis. The current study aimed at the analysis of miR-140 and miR-196a expression patterns and their clinical significance for breast cancer (BC) patients. METHODS Differentially expressed miR-140 and miR-196a were examined via quantitative PCR in 110 cases of BC and their adjacent non-tumor (ANT) tissues. RESULTS The results indicated that miR-140 and miR-196a, respectively, notably decreased and increased expression in BC samples in comparison with ANT (p<0.001). Reduced miR-140 expression was also related to Lymph node metastasis (LNM, P= 0.023) and stage (P = 0.009). Additionally, Receiver Operating Characteristics (ROC) analysis illustrated that miR-140 had a significant diagnostic accuracy for stage and LNM of BC patients. We also discovered a strong negative correlation between miR-196a expression with histological grade (P = 0.038), LNM (P = 0.012) and stage (P = 0.001). CONCLUSION Overall, exploring the miR-140 and miR-196a profiles not only can statistically different among BC and ANT samples, but it is also expected to become potential BC biomarkers. .

[PMID: 31461554 DOI: 10.1111/ocr.12341] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 07/28/2019] [Accepted: 08/26/2019] [Indexed: 01/08/2023]
Abstract
OBJECTIVE This study aimed to explore the role of miR-140-5p in cranial base synchondrosis chondrocytes (CBSCs) under cyclic tensile strain (CTS). SETTING AND SAMPLE POPULATION A total of 25 1-week-old Sprague Dawley rats from Shanghai Laboratory Animal Center, Chinese Academy of Sciences, were used. MATERIAL AND METHODS The second passage of CBSCs was applied with CTS at 10% elongation (1 Hz) for 24 hours. MiR-140-5p levels in CBSCs were detected by qRT-PCR. The role of miR-140-5p in CBSCs was evaluated by transfection of mimics and inhibitor. RNA sequencing and online search of miRNA databases (TargetScan, miRDB and miRanda) were used in prediction of miR-140-5p targets. A luciferase reporter assay was applied to identify the target gene of miR-140-5p. RESULTS Compared with the control, the expression of Col2a1 and Sox9 was significantly higher after CTS (P < .05). Also, CBSCs demonstrated higher expression of miR-140-5p after CTS loading for 24 hours (P < .05). Overexpression of miR-140-5p promoted ECM synthesis under CTS loading environment, while suppression of miR-140-5p inhibited the effect. Bloc1s2 was a putative target gene of miR-140-5p. CONCLUSIONS The expression of ECM in CBSCs could be promoted by CTS and miR-140-5p might play a role in this process through targeting Bloc1s2.

Abstract
BACKGROUND The neural crest (NC) is a class of transitory stem cell-like cells unique to vertebrate embryos. NC cells arise within the dorsal neural tube where they undergo an epithelial to mesenchymal transition in order to migrate and differentiate throughout the developing embryo. The derivative cell types give rise to multiple tissues, including the craniofacial skeleton, peripheral nervous system and skin pigment cells. Several well-studied gene regulatory networks underpin NC development, which when disrupted can lead to various neurocristopathies such as craniofrontonasal dysplasia, DiGeorge syndrome and some forms of cancer. Small RNAs, such as microRNAs (miRNAs) are non-coding RNA molecules important in post-transcriptional gene silencing and critical for cellular regulation of gene expression. RESULTS To uncover novel small RNAs in NC development we used high definition adapters and next generation sequencing of libraries derived from ectodermal explants of Xenopus laevis embryos induced to form neural and NC tissue. Ectodermal and blastula animal pole (blastula) stage tissues were also sequenced. We show that miR-427 is highly abundant in all four tissue types though in an isoform specific manner and we define a set of 11 miRNAs that are enriched in the NC. In addition, we show miR-301a and miR-338 are highly expressed in both the NC and blastula suggesting a role for these miRNAs in maintaining the stem cell-like phenotype of NC cells. CONCLUSION We have characterised the miRNAs expressed in Xenopus embryonic explants treated to form ectoderm, neural or NC tissue. This has identified novel tissue specific miRNAs and highlighted differential expression of miR-427 isoforms.

Abstract
Among the first found cancer-related long non-coding RNAs (lncRNAs), MALAT1 is one that involves in the development and progression of some tumors. MALAT1 can be aberrantly expressed in hepatocellular carcinoma, cervical, breast, ovarian cancers, as well as colorectal cancer. The paper aims to make certain the function of MALAT1 in human choriocarcinoma cell lines by investigating the detailed effects and molecular mechanisms. Being specifically upregulated in choriocarcinoma cell lines, the under-researched lncRNA-MALAT1 promoted choriocarcinoma cell growth by targeting miR-218. After MALAT1 knockdown, proliferation of human choriocarcinoma cell in vitro was dramatically hindered, and the tumor size in vivo was reduced. What is more, miR-218-mediated Fbxw8 regulation was required for MALAT1-induced choriocarcinoma cell proliferation. Taken together, MALAT1 might promote choriocarcinoma tumor growth through miR-218-mediated Fbxw8 regulation. According to our data, MALAT1 might be an oncogenic lncRNA that promoted choriocarcinoma proliferation and could be therapeutically targeted in human choriocarcinoma.

Abstract
Background Colorectal cancer (CRC) is one of the most common malignancies in the world. microRNA-140-5p (miR-140) has been shown to be involved in cartilage development and osteoarthritis (OA) pathogenesis. Some contradictions still exist concerning the role of miR-140 in tumor progression and metastasis, and the underlying mechanism is uncertain. Methods Immunohistochemistry was performed to determine the expressions of ADAMTS5 and IGFBP5 in CRC tissues. Human CRC cell lines HCT116 and RKO were transfected with miR-140 mimic, inhibitor, or small interfering RNA (siRNA) against ADAMTS5 or IGFBP5, respectively, using oligofectamine or lipofectamine 2000. Scratch-wound assay and transwell migration and invasion assays were used to evaluate the effects of miR-140 on the capabilities of migration and invasion. The levels of miR-140 and ADAMTS5 and IGFBP5 mRNA were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Western blot was performed to examine the expression of ADAMTS5 and IGFBP5 proteins. Results miR-140 was significantly reduced, whereas ADAMTS5 and IGFBP5 were upregulated, in the human CRC tissues compared to the corresponding normal colorectal mucosa. miR-140 downregulation and ADAMTS5 or IGFBP5 overexpression were associated with the advanced TNM stage and distant metastasis of CRC. There was a reverse correlation between miR-140 levels and ADAMTS5 and IGFBP5 expression in CRC tissues. ADAMTS5 and IGFBP5 were downregulated by miR-140 at both the protein and mRNA levels in the CRC cell lines. The gain-of- and loss-of-function studies showed that miR-140 inhibited CRC cell migratory and invasive capacities at least partially via downregulating the expression of ADAMTS5 and IGFBP5. Conclusions These findings suggest that miR-140 suppresses CRC progression and metastasis, possibly through downregulating ADAMTS5 and IGFBP5. miR-140 might be a potential therapeutic candidate for the treatment of CRC.

Abstract
Accumulating evidences suggest that lots of microRNAs (miRNAs) play crucial roles in (patho-)physiological processes of lung cancer, including metastasis, drug-resistance or tumorigenesis. They mediate the progression of cell growth, migration and invasion by regulating the expression of special genes. MiRNA expression patterns could also serve as diagnostic/prognostic biomarkers. Cancer therapies mediated by miRNAs remain tremendous potential and challenges. Our previous small RNA-seq assay found that the novel miR-9501 was down-regulated in lung cancer tissues compared with adjacent non-cancer tissues. In this study, our results verified that miR-9501 was significantly down-regulated in lung cancer tissues and its expression levels were remarkably suppressed in non-small cell lung cancer cell lines. Then, we characterized and investigated the novel miR-9501 in A549 cells. Transient transfection of miR-9501 into cultured A549 cells led to remarkable decrease in cell proliferation, migration and increase apoptosis. These data demonstrated that miR-9501 might be a tumor suppressor for lung cancer therapy.

Abstract
H19, one of the first found cancer-associated long non-coding RNAs (lncRNAs), is involved in the development and progression of many types of tumors. An aberrant expression of H19 was observed in hepatocellular carcinoma, cervical cancer, breast cancer, ovarian cancer, and colorectal cancer. However, the exact effects and molecular mechanisms of H19 in glioma progression are still unknown up to now. In this study, we investigated the role of H19 in human glioma cell lines and clinical tumor samples in order to determine the function of this molecule. In our research, lncRNA-H19 was specifically upregulated in glioma cell lines and promoted glioma cell growth through targeting miR-140. Knockdown of H19 inhibited the proliferation and invasion of human glioma cell and suppressed its metastasis in vitro and in vivo. In addition, miR-140 dependent inhibitor of apoptosis-stimulating protein of p53 (iASPP) regulation was required in H19 induced glioma cell growth. These findings indicated that H19 might regulate the tumor growth and metastasis via miR-140 dependent iASPP regulation. Taken together, our data indicated that H19 might be an oncogenic lncRNA that promoted proliferation and metastasis of glioma and could be regarded as a therapeutic target in human glioma.
