Involvement of the TNF-α/SATB2 axis in the induced apoptosis and inhibited autophagy of osteoblasts by the antipsychotic Risperidone. Mol Med 2022; 28:46. [PMID: 35505281 PMCID: PMC9066868 DOI: 10.1186/s10020-022-00466-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 03/31/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Risperidone, an atypical antipsychotic, impedes serotonin and dopamine receptor systems. Meanwhile, tumor necrosis factor-α (TNF-α) is known to participate in regulating osteoblast functions. Consequently, the current study aimed to investigate whether the influences of Risperidone on osteoblast functions are associated with TNF-α and special AT-rich sequence-binding protein (SATB2). METHODS Firstly, we searched the DGIdb, MEM and GeneCards databases to identify the critical factors involved in the effects of Risperidone on osteoblasts, as well as their interactions. Afterwards, osteoblast cell line MC3T3-E1 was transduced with lentivirus carrying si-TNF-α, si-SATB2 or both and subsequently treated with Risperidone. Various abilities including differentiation, autophagy and apoptosis of osteoblasts were examined after different treatments. Finally, animal experiments were performed with Risperidone alone or together with lentivirus to verify the function of Risperidone in vivo and the mechanism. RESULTS It was found that Risperidone might promote TNF-α expression, thereby inhibiting the expression of SATB2 to affect the autophagy and apoptosis in osteoblasts. Furthermore, as shown by our experimental findings, Risperidone treatment inhibited the differentiation and autophagy, and promoted the apoptosis of osteoblasts, as evidenced by elevated levels of OPG, p62, cleaved PARP1, cleaved caspase-3, cleaved caspase-8, and cleaved caspase-9, and reduced levels of LC3 II/I, Beclin1, collagen I, and RANKL. In addition, Risperidone was also found to elevate the expression of TNF-α to down-regulate SATB2, thereby inhibiting the differentiation and autophagy and enhancing the apoptosis of osteoblasts in vitro and in vivo. CONCLUSIONS Collectively, our findings indicated that Risperidone affects the differentiation of osteoblasts by inhibiting autophagy and enhancing apoptosis via TNF-α-mediated down-regulation of SATB2.

Abstract
Alcohol is a risk factor for hepatocellular carcinoma (HCC). However, the molecular mechanism by which chronic alcohol consumption contributes to HCC is not well understood. The purpose of the study was to demonstrate the effects of chronic ethanol exposure on the damage of human normal hepatocytes. Our data showed that chronic exposure of hepatocytes with ethanol induced changes similar to transformed hepatocytes that is, exhibited colonies and anchorage‐independent growth. These damaged hepatocytes contained high levels of reactive oxygen species (ROS) and showed induction of the SATB2 gene. Furthermore, damaged hepatocytes gained the phenotypes of CSCs which expressed stem cell markers (CD133, CD44, CD90, EpCAM, AFP and LGR5), and pluripotency maintaining factors (Sox‐2, POU5F1/Oct4 and KLF‐4). Ethanol exposure also induced Nanog, a pluripotency maintaining transcription factor that functions in concert with Oct4 and SOX‐2. Furthermore, ethanol induced expression of EMT‐related transcription factors (Snail, Slug and Zeb1), N‐Cadherin, and inhibited E‐cadherin expression in damaged hepatocytes. Ethanol enhanced recruitment of SATB2 to promoters of Bcl‐2, Nanog, c‐Myc, Klf4 and Oct4. Ethanol also induced activation of the Wnt/TCF‐LEF1 pathway and its targets (Bcl‐2, Cyclin D1, AXIN2 and Myc). Finally, ethanol induced hepatocellular steatosis, SREBP1 transcription, and modulated the expression of SREBP1c, ACAC, ACLY, FASN, IL‐1β, IL‐6, TNF‐α, GPC3, FLNB and p53. These data suggest that chronic alcohol consumption may contribute towards the development of HCC by damaging normal hepatocytes with the generation of inflammatory environment, induction of SATB2, stem cell‐like characteristics, and cellular steatosis.

Abstract
SATB2 (special AT-rich sequence-binding protein 2) is a member of the special AT-rich binding protein family. As a transcription regulator, SATB2 mainly integrates higher-order chromatin organization. SATB2 expression appears to be tissue- and stage-specific, and is governed by several cellular signaling molecules and mediators. Expressed in branchial arches and osteoblast-lineage cells, SATB2 plays a significant role in craniofacial pattern and skeleton development. In addition to regulating osteogenic differentiation, SATB2 also displays versatile functions in neural development and cancer progression. As an osteoinductive factor, SATB2 holds great promise in improving bone regeneration toward bone defect repair. In this review, we have summarized our current understanding of the physiological and pathological functions of SATB2 in craniofacial and skeleton development, neurogenesis, tumorigenesis and regenerative medicine.

Abstract
Dental mesenchymal stem cells (MSCs) are recognized as a critical factor in repair of defective craniofacial bone owing to the multiple differentiation potential, the ability to regenerate distinct tissues, and the advantage that they can be easily obtained by relatively noninvasive procedures. Special AT-rich sequence-binding protein 2 (SATB2) is a nuclear matrix protein, involved in chromatin remodeling and transcriptional regulation, and has been reported to be as a positive regulator of osteoblast differentiation, bone formation, and bone regeneration in MSCs. In this study, we systematically investigated the capability of SATB2 to promote the osteogenic differentiation of periodontal ligament stem cells (PDLSCs), dental pulp stem cells (DPSCs), and stem cells from human exfoliated deciduous teeth (SHED). RNA-seq analysis and quantitative real-time PCR (RT-PCR) revealed that genes regulating osteogenic differentiation were differentially expressed among three cell types and SATB2 was found to be expressed at a relatively high level. When the three cell types overexpressed SATB2 with AdSATB2 infection, alkaline phosphatase (ALP) staining, ALP activity, Alizarin Red S staining, and quantification tended to increase with an increasing infection rate. It showed opposite results after infection with AdsiSATB2. RNA-seq analysis indicated that the expression of downstream osteogenic genes was affected by AdSATB2 infection and quantitative RT-PCR confirmed that nine osteogenic genes (Spp1, Sema7a, Atf4, Ibsp, Col1a1, Sp7, Igfbp3, Dlx3, and Alpl) were upregulated, to various extents, following SATB2 overexpression. In addition, quantitative PCR results indicated that SATB2 affected the expression of MSC markers. These results suggested an important role of SATB2 in the osteogenesis of PDLSCs, DPSCs, and SHED. Further research is warranted to investigate SATB2-mediated regulation of osteogenic differentiation and to evaluate the therapeutic use of SATB2 for the regeneration of defective craniofacial bone tissue.

Abstract
Special AT-rich sequence binding protein 2 (Satb2) is a matrix attachment region (MAR) binding protein. Satb2 impacts skeletal development by regulating gene transcription required for osteogenic differentiation. Although its role as a high-order transcription factor is well supported, other roles for Satb2 in skeletal development remain unclear. In particular, the impact of dosage sensitivity (heterozygous mutations) and variance on phenotypic severity is still not well understood. To further investigate molecular and cellular mechanisms of Satb2-mediated skeletal defects, we used the CRISPR/Cas9 system to generate Satb2 mutations in MC3T3-E1 cells. Our data suggest that, in addition to its role in differentiation, Satb2 regulates progenitor proliferation. We also find that mutations in Satb2 cause chromatin defects including nuclear blebbing and donut-shaped nuclei. These defects may contribute to a slight increase in apoptosis in mutant cells, but apoptosis is insufficient to explain the proliferation defects. Satb2 expression exhibits population-level variation and is most highly expressed from late G1 to late G2. Based on these data, we hypothesize that Satb2 may regulate proliferation through two separate mechanisms. First, Satb2 may regulate the expression of genes necessary for cell cycle progression in pre-osteoblasts. Second, similar to other MAR-binding proteins, Satb2 may participate in DNA replication. We also hypothesize that variation in the severity or penetrance of Satb2-mediated proliferation defects is due to stochastic variation in Satb2 binding to DNA, which may be buffered in some genetic backgrounds. Further elucidation of the role of Satb2 in proliferation has potential impacts on our understanding of both skeletal defects and cancer.

Abstract
Special AT-rich sequence binding protein 2 (SATB2) is a member of the special family of AT-rich binding transcription factors and has a critical role in osteoblast differentiation and craniofacial patterning. However, the expression and distribution of SATB2 in tooth development is largely unknown. The aim of the present study was to detect the expression and distribution of SATB2 during murine molar development and, in human healthy teeth and teeth with pulpitis using immunohistochemistry. Molars were obtained from Kunming mice at embryonic day (E) 13.5, E14.5, E16.5 and E18.5, and postnatal day (P) 1, P5 and P7. In addition, 20 human teeth (10 healthy and 10 teeth with pulpitis) were obtained from young adult patients (age, 24.90±1.65 years) who were scheduled for routine extraction. Immunohistochemical analyses were performed to detect the expression and distribution of SATB2. The present results revealed that SATB2 exhibits a spatiotemporal expression pattern in murine molar development and was expressed in odontoblasts, predentin, dental pulp cells and the blood vessels in human teeth. These findings suggested that SATB2 may have an important role in odontoblast differentiation and dentin matrix mineralization during tooth development.

Abstract
Satb2 is a special AT-rich binding transcription factor essential for osteoblast differentiation and bone formation. Specific microRNAs (miRNAs) have been identified to regulate the complex process of osteogenic differentiation. It remains unclear how miRNA expressions is changed in the Satb2-induced osteogenic differentiation of bone marrow stromal cells (BMSCs). From the miRNA expression profile data collected by us from Satb2-induced osteogenic differentiation of mouse BMSCs, we found that miR-27a was significantly down-regulated relative to non-treated cells 7 days post induction. By in silico analysis, we identified Sp7 as a miR-27a targeting gene and verified the findings by Western blot analysis, qRT-PCR, and luciferase reporter assays. We also analyzed the function of miR-27a in osteogenic differentiation by transfection of exogenous miR-27a into BMSCs. Overexpression of miR-27a remarkably inhibited the expression of Sp7 and attenuated Satb2-induced osteogenic differentiation. Our results suggest that expression of Sp7 during the early stage of Satb2-induced osteogenic differentiation of BMSCs is regulated by miR-27a.

Abstract
Bone mesenchymal stem cells (BMSCs) have multiple potentials to differentiate into osteoblasts and adipocytes, and methods to enhance their osteogenic differentiation are gaining increasing attention. MicroRNAs are critical regulation factors during the process of the osteogenic induction in BMSCs, and mir-205 has been substantiated to be involved in the osteogenic process, but the underlying mechanisms remain unclear. The purpose of this article is to investigate the role of mir-205 in the osteogenic differentiation of BMSCs. We found that mir-205 expression was down-regulated in a time-dependent manner during BMSC osteo-induction. Inhibition of mir-205 enhanced osteogenic abilities by up-regulating bone sialoprotein (BSP) and osteopontin (OPN) protein levels and increasing alkaline phosphatase (ALP) activity and osteocalcin secretion. Furthermore, we found that mir-205 could regulate protein expression of special AT-rich sequence-binding protein 2 (SATB2) and runt-related transcription factor 2 (Runx2), and over-expression of SATB2 activated Runx2 and reversed the negative effects of mir-205 on osteoblastic differentiation. Furthermore, we examined the extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (p38 MAPK) pathways during osteogenic induction and our data indicates that mir-205 might exert negative functions on the osteogenic differentiation in BMSCs at least partly via altering phosphorylation of ERK and p38 MAPK. These results shed new light on the molecular mechanisms of microRNAs in governing differentiation of BMSCs.

Abstract
Craniofacial bone marrow mesenchymal stem cells (BMSCs) display some site-specific properties that differ from those of BMSCs derived from the trunk and appendicular skeleton, but the characteristics of craniofacial BMSCs and the mechanisms that underlie their properties are not completely understood. Previous studies indicated that special AT-rich binding protein 2 (SATB2) may be a potential regulator of craniofacial skeletal patterning and site-specific osteogenic capacity. Here, we investigated the stemness, autophagy, and anti-aging capacity of mandible-derived BMSCs (M-BMSCs) and tibia-derived BMSCs (T-BMSCs) and explored the role of SATB2 in regulating these properties. M-BMSCs not only possessed stronger expression of SATB2 and stemness markers (pluripotency genes, such as Nanog, OCT-4, Sox2, and Nestin) but also exhibited stronger autophagy and anti-aging capacities under normal or hypoxia/serum deprivation conditions compared to T-BMSCs. Exogenous expression of SATB2 in T-BMSCs significantly enhanced the expression of pluripotency genes as well as autophagy and anti-aging capacity. Moreover, SATB2 markedly enhanced osteogenic differentiation of BMSCs in vitro, and promoted bone defect regeneration and the survival of BMSCs that were transplanted into mandibles with critical size defects. Mechanistically, SATB2 upregulates pluripotency genes and autophagy-related genes, which in turn activate the mechanistic target of rapamycin signaling pathway. Collectively, our results provide novel evidence that site-specific BMSCs have distinct biological properties and suggest that SATB2 plays a potential role in regulating the stemness, autophagy, and anti-aging properties of craniofacial BMSCs. The application of SATB2 to manipulate stem cells for the reconstruction of bone defects might represent a new approach.

Abstract
BACKGROUND Transcription factors have been implicated in regulating the differentiation of odontoblasts from dental pulp stem cells/progenitors (DPSCs/progenitors), but their regulatory network is not completely understood. RESULT New transcription factors that control the odontoblast differentiation of human DPSCs/progenitors were analyzed using a microarray. The result revealed bobby sox homolog (BBX) to be expressed most strongly during odontoblast differentiation. Validation using RT-PCR also revealed the strong expression of BBX during the odontoblast differentiation of DPSCs/progenitors. BBX expression was also detected in adult molar odontoblasts and other tissues, including the heart, kidney, testis, and bone marrow. To understand the role of BBX in odontoblast differentiation, BBX variant 1 and 2 cDNA were cloned and overexpressed in DPSCs/progenitors. The results showed that the overexpression of BBX cDNA in DPSCs/progenitors induced substantial mineralization and expression of the odontoblast marker genes, such as ALP, OPN, BSP, DMP1, and DSPP. The knockdown of BBX using shRNA, however, did not affect mineralization, but the expression of ALP and DSPP was decreased substantially. Meanwhile overexpression or knockdown of BBX did not modulate proliferation of DPSCs/progenitors. CONCLUSION Our results suggest that BBX plays an important role during the odontoblast differentiation of human DPSCs/progenitors.

Abstract
In the course of embryonic development skeletal elements form either through intramembranous or endochondral ossification. Wnt proteins play diverse roles during vertebrate skeletal development. Wnt16 is a key factor in developing long bones, but its exact role in craniofacial bone formation remains unclear. This study was initially undertaken to investigate the expression of Wnt16 during craniofacial bone development in mouse embryos. Wnt16 expression in the osteoid of calvaria, maxilla, and mandible started later than that of ALP and osteocalcin (OCN), but before mineralization of the craniofacial bones, suggesting that Wnt16 is involved in intramembranous ossification in the head. To confirm this, MC3T3-E1 cells were transfected with an adenovirus containing Wnt16 (Ad-Wnt16). Ad-Wnt16 cells showed decreased ALP activity and less mineralized nodule formations compared with control cells. In addition, the mRNA levels of osteogenic markers were reduced. Moreover, Wnt16 activated β-catenin signaling in MC3T3-E1 cells at both transcription and protein levels as shown by a TOPflash luciferase reporter gene assay and western blot analysis. On the other hand, Wnt/β-catenin pathway blockade by Dickkopf 1 abrogated the suppression of mineralization by Wnt16. Our findings suggest that Wnt16 is involved in intramembranous ossification and suppresses osteoblast differentiation through the Wnt/β-catenin pathway.

Abstract
Since the discovery of SATB2 (special AT-rich sequence binding protein 2) a decade ago, its pivotal roles in development and tissue regeneration have emerged, particularly in craniofacial patterning and development, palate formation, and osteoblast differentiation and maturation. As a member of the special AT-rich binding proteins family that bind to nuclear matrix-attachment regions (MAR), it also displays functional versatility in central nervous development, especially corpus callosum and pons formation, cancer development and prognosis, as well as in immune regulation. At the molecular level, Satb2 gene expression appears to be tissue and stage-specific, and is regulated by several cytokines and growth factors, such as BMP2/4/7, insulin, CNTF, and LIF via ligand receptor signaling pathways. SATB2 mainly performs a twofold role as a transcription regulator by directly binding to AT-rich sequences in MARs to modulate chromatin remodeling, or through association with other transcription factors to modulate the cis-regulation elements and thus to regulate the expression of down-stream target genes and a wide range of biological processes. This contemporary review provides an exploration of the molecular characteristics and function of SATB2; including its expression and cytokine regulation, its involvement in human disease, and its potential roles in skeletogenesis.

MicroRNA expression signature for Satb2-induced osteogenic differentiation in bone marrow stromal cells. Mol Cell Biochem 2013; 387:227-39.

Abstract
Satb2 acts as a potent transcription factor to promote osteoblast differentiation and bone regeneration. Recently, microRNAs (miRNA) have been identified as critical regulators of osteogenic differentiation. This study aimed to identify specific miRNAs and their regulatory roles in the process of Satb2-induced osteogenic differentiation. We studied the differentially expressed miRNAs by Satb2 overexpression in murine bone marrow stromal cells using miRNA microarray. Ten down-regulated miRNAs including miR-27a, miR-125a-5p, and miR-466f-3p, and 18 up-regulated miRNAs including miR-17, miR-20a and miR-210 were found to be differentially expressed and their expression were verified by quantitative real time PCR. The differentially expressed miRNAs were further subjected to gene ontology and KEGG analysis. The highly enriched GOs and KEGG pathway showed target genes of these miRNAs were significantly involved in multiple biological processes (mesenchymal cell differentiation, bone formation, and skeletal development), and several osteogenic pathways (TGF-β/BMP, MAPK, and Wnt signaling pathway). Finally, miR-27a was selected for target verification and function analysis. BMP2, BMPR1A, and Smad9, members of the TGF-β/BMP superfamily, which were predicted to be target genes of miR-27a, were confirmed to be significantly up-regulated in Satb2-overexpressing cells by quantitative real time PCR. Overexpression of miR-27a significantly inhibited osteogenesis and repressed BMP2, BMPR1A, and Smad9 expression. In this study, we identified that a number of differentially regulated miRNAs, whose target genes involved in the TGF-β/BMP signaling pathway, play an important role in the early stage of Satb2-induced osteogenic differentiation.
