Abstract
OBJECTIVE Runt-related transcription factor 2 (Runx2) plays an important role in bone metabolism; however, the relationship between Runx2 and periodontitis remains unclear. We investigated Runx2 expression in the gingiva of patients to explore its role in periodontitis. METHODS Gingival samples of patients were collected, including healthy samples (control group) and periodontitis samples (P group). Periodontitis samples were divided into three groups based on the periodontitis stage. Samples with stage I and grade B periodontitis were in the P1 group, stage II and grade B in the P2 group, and stage III or IV and grade B in the P3 group. Immunohistochemistry and western blotting were performed to detect Runx2 levels. The probing (PD) and clinical attachment loss (CAL) were recorded. RESULTS Runx2 expression levels in the P and P3 groups were higher than those in the control group. In addition, Runx2 expression was positively correlated with CAL and PD (r1 = 0.435, r2 = 0.396). CONCLUSION The high expression level of Runx2 in the gingiva of patients with periodontitis may be correlated with the pathogenesis of periodontitis.

Abstract
AIM Necroptosis participates in the pathogenesis of many inflammatory diseases, including periodontitis. Here, we aimed to investigate the role and mechanism of necroptosis inhibitors in attenuating periodontitis. MATERIALS AND METHODS The Gene Expression Omnibus (GEO) dataset GSE164241 was re-analysed to identify the role of necroptosis in periodontitis. Gingival specimens from healthy subjects or periodontitis patients were collected to evaluate the expression level of necroptosis-associated proteins. The therapeutic effect of necroptosis inhibitors on periodontitis was assessed in vivo and in vitro. Moreover, Transwell assays and Western blotting and siRNA transfection were used to identify the effects of necroptotic human gingival fibroblasts (hGFs) on THP-1 macrophages. RESULTS Re-analysis revealed that gingival fibroblasts (GFs) in periodontitis gingiva showed the highest area under the curve score of necroptosis. Elevated levels of necroptosis-associated proteins were identified in GFs in periodontitis gingiva collected from patients and mice. In ligature-induced periodontitis mice, local administration of receptor interacting protein kinase 3(RIPK3) inhibitor GSK'872 or sh-mixed-lineage kinase domain-like pseudokinase (Mlkl) markedly abrogated necroptosis and rescued periodontitis. Analogously, necroptosis inhibitors alleviated the inflammatory response and release of damage-associated molecular patterns in lipopolysaccharide- or LAZ (LPS + AZD'5582 + z-VAD-fmk, necroptosis inducer)-induced GFs and then reduced THP-1 cell migration and M1 polarization. CONCLUSIONS Necroptosis in GFs aggravated gingival inflammation and alveolar bone loss. Necroptosis inhibitors attenuate this process by modulating THP-1 macrophage migration and polarization. This study offers novel insights into the pathogenesis and potential therapeutic targets of periodontitis.

Abstract
Systems biology is a promising scientific discipline that allows an integrated investigation of host factors, microbial composition, biomarkers, immune response and inflammatory mediators in many conditions such as chronic diseases, cancer, neurological disorders, and periodontitis. This concept utilizes genetic decoding, bioinformatic, flux-balance analysis in a comprehensive approach. The aim of this review is to better understand the current literature on systems biology and identify a clear applicability of it to periodontitis. We will mostly focus on the association between this condition and topics such as genomics, transcriptomics, proteomics, metabolomics, as well as contextualize delivery systems for periodontitis treatment, biomarker detection in oral fluids and associated systemic conditions.

Abstract
Fibroblasts constitute a ubiquitous mesenchymal cell type and produce the extracellular matrix (ECM) of connective tissue, thereby providing the structural basis of various organs. Fibroblasts display differential transcriptional patterns unique to the organ of their origin and they can be activated by common stimuli such as transforming growth factor-β (TGF-β) and platelet-derived growth factor (PDGF) signaling. Cancer-associated fibroblasts (CAFs) reside in the cancer tissue and contribute to cancer progression by influencing cancer cell growth, invasion, angiogenesis and tumor immunity. CAFs impact on the tumor microenvironment by remodeling the ECM and secreting soluble factors such as chemokines and growth factors. Differential expression patterns of molecular markers suggest heterogeneous features of CAFs in terms of their function, pathogenic role and cellular origin. Recent studies elucidated the bimodal action of CAFs on cancer progression and suggest a subgroup of CAFs with tumor-suppressive effects. This review attempts to describe cellular features of colorectal CAFs with an emphasis on their heterogeneity and functional diversity.

Abstract
OBJECTIVES Periodontitis is a chronic inflammatory process associated with the loss of tooth-supporting tissue. The imbalance of epithelial-mesenchymal signaling is considered to drive disease progression, and hepatocyte growth factor (HGF) is one of the main mediators of this interaction. The aim of this study was to validate the role of HGF in the pathogenesis of periodontitis and to evaluate the effects of anti-HGF neutralizing antibodies. METHODS Gingival tissues from cynomolgus monkeys, which naturally develop severe periodontitis, were isolated to establish an in vitro periodontitis model. Periodontitis-affected monkeys were treated by gingival injection of anti-HGF neutralizing antibodies. The therapeutic effects were documented by clinical examination (probing depth and bleeding on probing), histological examination of tissue, and reevaluation of gingival fibroblasts in the in vitro model. RESULTS Periodontitis-affected monkeys contain periodontitis-associated fibroblasts (PAFs) with a pro-inflammatory phenotype that induced pronounced collagen degradation in vitro. This degradation was effectively inhibited by anti-HGF-neutralizing antibodies. Locally administered anti-HGF antibody to monkey gingiva clinically improved the severity of periodontitis. This was also reflected in the tissue histology with lower inflammatory cell infiltrates in treated gingiva than in non-treated gingiva. Moreover, fibroblasts isolated from anti-HGF-treated gingiva demonstrated reduced collagen degradation capacity. CONCLUSIONS Our study confirmed the central role of HGF in the pathogenesis of severe periodontitis in relevant in vitro and in vivo models. The positive effect of anti-HGF treatment provides a strong rationale for the use of anti-HGF-neutralizing antibodies for the treatment of human periodontitis.

Am J Cancer Res 2021; 11:3354-3374.

Abstract
The distal-less (dlx) homeobox transcription factors have been implicated roles in bone development. DLX5, in particular, was shown to play essential roles in osteoblast differentiation by targeting RUNX2, a master transcription factor for bone development. Interestingly, DLX5 has also been shown to play an oncogenic role in lung and other cancers, possibly via regulation of MYC expression. Given its dual roles in bone and cancer, this study aimed to investigate the effect of DLX5 on progression of osteosarcoma (OS), the primary bone cancer that is characterized by abnormal bone formation and osteoblast activity. Expression of DLX5 in OS cell lines was detected by quantitative real-time PCR (qRT-PCR) and western blot (WB). In vitro and in vivo assays were performed to investigate the oncogenic function of DLX5 in OS cells and xenograft models. Luciferase reporter assay was performed to determine the underlying mechanism of DLX5-mediated OS aggressiveness. The results showed that DLX5 was differentially expressed in OS cell lines, with significantly upregulated levels in HOS and MG-63 and relatively low levels in U2OS and 143B cell lines, compared with the normal bone cell line. DLX5 knockdown in HOS and MG-63 cell lines by siRNA inhibited OS cell growth and progression, and induced cell apoptosis and cell cycle changes both in vitro and in vivo. Meanwhile, DLX5 overexpression had the opposite effect on U2OS and 143B cell lines. Notably, a positive correlation between the expression patterns of NOTCH1 and DLX5 was also observed. The expression levels of NICD (NOTCH1 intracellular domain) and HES1 (classical target of NOTCH) were closely associated with DLX5 expression. Whereas knockdown of DLX5 in OS cells resulted in decreased expression of NOTCH1 and reduced cell proliferation and migration, which were rescued by overexpression of NOTCH1. We further analyzed DLX5 and NOTCH1 genes using JASPAR software and found two potential DLX5 binding sites within the NOTCH1 promoter. Dual-luciferase assay demonstrated that DLX5 specifically activates the NOTCH1 promoter and controls its expression. Taken together, our results support that DLX5 plays an oncogenic role in OS development, which can at least partially, be attributed to activation of the NOTCH signaling pathway.

Abstract
Periodontitis is a chronic inflammatory disease leading to progressive connective tissue degradation and loss of the tooth-supporting bone. Clinical and experimental studies suggest that hepatocyte growth factor (HGF) is involved in the dysregulated fibroblast–epithelial cell interactions in periodontitis. The aim of this study was to explore effects of HGF to impact fibroblast-induced collagen degradation. A patient-derived experimental cell culture model of periodontitis was applied. Primary human epithelial cells and fibroblasts isolated from periodontitis-affected gingiva were co-cultured in a three-dimensional collagen gel. The effects of HGF neutralizing antibody on collagen gel degradation were tested and transcriptome analyses were performed. HGF neutralizing antibody attenuated collagen degradation and elicited expression changes of genes related to extracellular matrix (ECM) and cell adhesion, indicating that HGF signaling inhibition leads to extensive impact on cell–cell and cell–ECM interactions. Our study highlights a potential role of HGF in periodontitis. Antagonizing HGF signaling by a neutralizing antibody may represent a novel approach for periodontitis treatment.

Abstract
Genome-wide transcriptomic analyses in whole tissues reflect the aggregate gene expression in heterogeneous cell populations comprising resident and migratory cells, and they are unable to identify cell type-specific information. We used a computational method (population-specific expression analysis [PSEA]) to decompose gene expression in gingival tissues into cell type-specific signatures for 8 cell types (epithelial cells, fibroblasts, endothelial cells, neutrophils, monocytes/macrophages, plasma cells, T cells, and B cells). We used a gene expression data set generated using microarrays from 120 persons (310 tissue samples; 241 periodontitis affected and 69 healthy). Decomposition of the whole-tissue transcriptomes identified differentially expressed genes in each of the cell types, which mapped to biologically relevant pathways, including dysregulation of Th17 cell differentiation, AGE-RAGE signaling, and epithelial-mesenchymal transition in epithelial cells. We validated selected PSEA-predicted, differentially expressed genes in purified gingival epithelial cells and B cells from an unrelated cohort (n = 15 persons), each of whom contributed with 1 periodontitis-affected and 1 healthy gingival tissue sample. Differential expression of these genes by quantitative reverse transcription polymerase chain reaction corroborated the PSEA predictions and pointed to dysregulation of biologically important pathways in periodontitis. Collectively, our results demonstrate the robustness of the PSEA in the decomposition of gingival tissue transcriptomes and its ability to identify differentially regulated transcripts in particular cellular constituents. These genes may serve as candidates for further investigation with respect to their roles in the pathogenesis of periodontitis.

Abstract
Fibroblasts provide a structural framework for multiple organs and are essential for wound repair and fibrotic processes. Here, we demonstrate functional roles of FOXL1 (forkhead box L1), a transcription factor that characterizes the pulmonary origin of lung fibroblasts. We detected high FOXL1 transcripts associated with DNA hypomethylation and super-enhancer formation in lung fibroblasts, which is in contrast with fibroblasts derived from other organs. RNA in situ hybridization and immunohistochemistry in normal lung tissue indicated that FOXL1 mRNA and protein are expressed in submucosal interstitial cells together with airway epithelial cells. Transcriptome analysis revealed that FOXL1 could control a broad array of genes that potentiate fibroblast function, including TAZ (transcriptional coactivator with PDZ-binding motif)/YAP (Yes-associated protein) signature genes and PDGFRα (platelet-derived growth factor receptor-α). FOXL1 silencing in lung fibroblasts attenuated cell growth and collagen gel contraction capacity, underscoring the functional importance of FOXL1 in fibroproliferative reactions. Of clinical importance, increased FOXL1 mRNA expression was found in fibroblasts of idiopathic pulmonary fibrosis lung tissue. Our observations suggest that FOXL1 regulates multiple functional aspects of lung fibroblasts as a key transcription factor and is involved in idiopathic pulmonary fibrosis pathogenesis.

Abstract
Although both estrogen deficiency and diabetes contribute to periodontal tissue deterioration, the combined effects of these conditions on periodontium is unknown. Thus, we analyzed the combined effects of ovariectomy followed by streptozotocin (STZ)-induced diabetes on periodontal tissues of rats. Twenty adult rats were ovariectomized (OVX) or SHAM-operated (SHAM). After 3 weeks, the rats received an intraperitoneal injection of STZ (60 mg/kg/body weight) to induce diabetes or vehicle (blank) solution. The groups were assigned as follows (n = 5): SHAM-vehicle (SHAM), OVX-vehicle (OVX), SHAM + STZ (SHAM-Di), and OVX + STZ (OVX-Di). Seven weeks post-diabetes induction, the rats were euthanized. Blood samples were collected for glucose measurements and maxillae were processed for paraffin embedding. Sections stained with hematoxylin/eosin, Masson's trichrome, and picrosirius-red were used for alveolar bone loss and collagen fiber analysis in the lamina propria. Immunohistochemistry was performed for runt-related transcription factor 2 (Runx2), matrix metalloproteinase 9 (MMP-9), and tryptase detection. Alveolar bone loss and fewer collagen fibers were observed in the OVX-Di group, collagen fibers with irregular organization, and MMP-9 immunoreactivity were more evident in diabetic groups, and MMP-9-positive osteoclasts on alveolar bone surface were noticed in all groups. The OVX-Di group showed lower Runx2 immunoreactivity (osteoblast formation marker), and more tryptase-positive cells (mast cell marker) in the alveolar bone marrow. Our results indicate that estrogen depletion, followed by STZ-induced diabetes, promotes periodontal tissue deterioration that is more evident than both interventions applied alone. Furthermore, our results points to a possible participation of bone-derived mast cells in this process.

Abstract
Periodontal studies using transcriptomics, proteomics, and metabolomics encompass the collection of mRNA transcripts, proteins, and small-molecule chemicals in the context of periodontal health and disease. The number of studies using these approaches has significantly increased in the last decade and they have provided new insight into the pathogenesis and host-microbe interactions that define periodontal diseases. This review provides an overview of current molecular findings using -omic approaches that underlie periodontal disease, including modulation of the host immune response, tissue homeostasis, and complex metabolic processes of the host and the oral microbiome. Integration of these -omic approaches will broaden our perspective of the molecular mechanisms involved in periodontal disease, advancing and improving the diagnosis and treatment of various stages and forms of periodontal disease.

Regenerative potential of cultured gingival fibroblasts in treatment of periodontal intrabony defects (randomized clinical and biochemical trial). J Periodontal Res 2020; 55:441-452. [PMID: 32080858 DOI: 10.1111/jre.12728] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 11/22/2019] [Accepted: 12/11/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Defective cellular elements constitute an important challenge to achieve predictable periodontal regeneration. In an attempt to improve the cellularity of periodontal defects, gingival fibroblasts were implanted without their associated extracellular elements in periodontal defects to expose them to periodontal tissue mediators. In order to investigate the regenerative potential of gingival fibroblasts translocated into periodontal defects, the present study was designed to clinically and biochemically investigate the use of gingival fibroblasts (GF) and their associated mesenchymal stem cells (GMSC) in the treatment of intrabony periodontal defects. METHODS A total of 20 subjects were randomly divided into two groups (n = 20). Group I: ten patients were included with ten intrabony periodontal defects that received β-calcium triphosphate (β-TCP) followed by collagen membrane defect coverage, while group II: (10 patients) ten periodontal defects received cultured gingival fibroblasts (GF) on the β-TCP scaffold and covered by a collagen membrane. The clinical evaluation was carried out at the beginning and at 6 months. Gingival crevicular fluid (GCF) samples were collected directly from the test sites for the quantitative measurement of PDGF-BB and BMP-2 using the ELISA kit at 1, 7, 14, and 21 days after surgery. RESULTS Group II reported a significantly greater reduction in vertical pocket depth (VPD) and CAL gain compared with group I after 6 months. Radiographic bone gain was statistically higher in group II compared with group I. A significantly higher concentration of PDGF-BB was observed in group II on days 1, 3, and 7 compared with group I. CONCLUSIONS Translocation of gingival fibroblasts from gingival tissue to periodontal defects could be a promising option that increases cellular elements with regeneration potential. The concept of total isolation of gingival fibroblasts using occlusive membranes must be re-evaluated.

Abstract
The secondary palate arises from outgrowths of epithelia-covered embryonic mesenchyme that grow from the maxillary prominence, remodel to meet over the tongue, and fuse at the midline. These events require the coordination of cell proliferation, migration, and gene expression, all of which take place in the context of the extracellular matrix (ECM). Palatal cells generate their ECM, and then stiffen, degrade, or otherwise modify its properties to achieve the required cell movement and organization during palatogenesis. The ECM, in turn, acts on the cells through their matrix receptors to change their gene expression and thus their phenotype. The number of ECM-related gene mutations that cause cleft palate in mice and humans is a testament to the crucial role the matrix plays in palate development and a reminder that understanding that role is vital to our progress in treating palate deformities. This article will review the known ECM constituents at each stage of palatogenesis, the mechanisms of tissue reorganization and cell migration through the palatal ECM, the reciprocal relationship between the ECM and gene expression, and human syndromes with cleft palate that arise from mutations of ECM proteins and their regulators.

Abstract
Aging is broadly defined as the functional decline that occurs in all body systems. The accumulation of senescent cells is considered a hallmark of aging and thought to contribute to the aging pathologies. Transforming growth factor-β (TGF-β) is a pleiotropic cytokine that regulates a myriad of cellular processes and has important roles in embryonic development, physiological tissue homeostasis, and various pathological conditions. TGF-β exerts potent growth inhibitory activities in various cell types, and multiple growth regulatory mechanisms have reportedly been linked to the phenotypes of cellular senescence and stem cell aging in previous studies. In addition, accumulated evidence has indicated a multifaceted association between TGF-β signaling and aging-associated disorders, including Alzheimer’s disease, muscle atrophy, and obesity. The findings regarding these diseases suggest that the impairment of TGF-β signaling in certain cell types and the upregulation of TGF-β ligands contribute to cell degeneration, tissue fibrosis, inflammation, decreased regeneration capacity, and metabolic malfunction. While the biological roles of TGF-β depend highly on cell types and cellular contexts, aging-associated changes are an important additional context which warrants further investigation to better understand the involvement in various diseases and develop therapeutic options. The present review summarizes the relationships between TGF-β signaling and cellular senescence, stem cell aging, and aging-related diseases.

Abstract
Lung fibroblasts participate in the pathogenesis of respiratory diseases, including lung cancer and pulmonary fibrosis. Although fibroblasts are ubiquitous constituents of various organs, their cellular diversity among different organs has been poorly characterized. Here, we aimed to investigate the distinct gene signature of lung fibroblasts that represents its pulmonary origin and the underlying gene regulatory networks. Promoter-level differential expression analysis by cap analysis of gene expression (CAGE) sequencing revealed distinct gene expression patterns of fibroblasts derived from different anatomical sites and identified 88 coding genes with higher expression in lung fibroblasts relative to other fibroblasts. Multiple key transcription factors important for lung mesenchyme development, including the T-box transcription factors TBX2, TBX4, and TBX5 were enriched in this lung-specific signature and were associated with super-enhancers. TBX4 showed highly specific expression in lung fibroblasts and was required for cell proliferation and collagen gel contraction capacity. Transcriptome analysis revealed that TBX4 could broadly regulate fibroblast-related pathways and partly contribute to super-enhancer-mediated transcriptional programs. Of pathological importance, lung fibroblast-specific genes were globally downregulated in lung cancer-associated fibroblasts (CAFs). Notably, TBX2, TBX4, and TBX5 were downregulated and hypermethylated in lung CAFs, suggesting an association between epigenetic silencing of these factors and phenotypic alteration of lung fibroblasts in cancer. Our study highlights the importance of T-box transcription factors, especially TBX4, and super-enhancers in the roles of lung fibroblasts in pulmonary physiology and pathogenesis.
