Abstract
AIM Resveratrol is a natural polyphenolic compound with biological activities such as anti-inflammation and antioxidation. Its anti-fibrotic effect has been experimentally demonstrated in the pancreas and liver. This study aims to determine the anti-proliferative effect of resveratrol on fibroblasts obtained from hyperplastic gingival tissues from a patient diagnosed with Juvenile Hyaline Fibromatosis (JHF). MATERIALS AND METHODS Primary gingival fibroblast cell lines were obtained from gingival growth tissues by the gingivectomy of a patient with JHF. Gingival fibroblasts were treated with or without 3 different doses of resveratrol (50, 100, 200 µM). Cytotoxicity and cell proliferation were evaluated after 24, 48, and 72 h. Collagen, TGF, and CTGF were analyzed by ELISA in the 48-hour supernatants. RESULTS All three doses of resveratrol suppressed the proliferation of JHF gingival fibroblasts at 24 and 48 h without showing any cytotoxic effect compared to the control group (p < 0.0001). At 72 h, 100 and 200 µM resveratrol showed significantly less proliferation (p < 0.0001), less collagen, CTGF, and TGF- β (p < 0.001) than the control group. CONCLUSION Resveratrol had a profound anti-proliferative effect on gingival fibroblasts obtained from gingival enlargements with JHF, suggesting that it can be used as a therapeutic to prevent excessive cell growth by suppressing collagen, CTGF, and TGF- β synthesis in the pathogenesis of hyperplasia.

Abstract
Raine syndrome (RNS) is a rare autosomal recessive osteosclerotic dysplasia. RNS is caused by loss-of-function disease-causative variants of the FAM20C gene that encodes a kinase that phosphorylates most of the secreted proteins found in the body fluids and extracellular matrix. The most common RNS clinical features are generalized osteosclerosis, facial dysmorphism, intracerebral calcifications and respiratory defects. In non-lethal RNS forms, oral traits include a well-studied hypoplastic amelogenesis imperfecta (AI) and a much less characterized gingival phenotype. We used immunomorphological, biochemical, and siRNA approaches to analyze gingival tissues and primary cultures of gingival fibroblasts of two unrelated, previously reported RNS patients. We showed that fibrosis, pathological gingival calcifications and increased expression of various profibrotic and pro-osteogenic proteins such as POSTN, SPARC and VIM were common findings. Proteomic analysis of differentially expressed proteins demonstrated that proteins involved in extracellular matrix (ECM) regulation and related to the TGFβ/SMAD signaling pathway were increased. Functional analyses confirmed the upregulation of TGFβ/SMAD signaling and subsequently uncovered the involvement of two closely related transcription cofactors important in fibrogenesis, Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ). Knocking down of FAM20C confirmed the TGFβ-YAP/TAZ interplay indicating that a profibrotic loop enabled gingival fibrosis in RNS patients. In summary, our in vivo and in vitro data provide a detailed description of the RNS gingival phenotype. They show that gingival fibrosis and calcifications are associated with, and most likely caused by excessed ECM production and disorganization. They furthermore uncover the contribution of increased TGFβ-YAP/TAZ signaling in the pathogenesis of the gingival fibrosis.

Bioengineering (Basel) 2024; 11:65. [PMID: 38247942 PMCID: PMC10813134 DOI: 10.3390/bioengineering11010065] [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: 11/21/2023] [Revised: 12/28/2023] [Accepted: 01/05/2024] [Indexed: 01/23/2024] Open
Abstract
Oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC) represent a significant global health burden due to their potential for malignant transformation and the challenges associated with their diagnosis and treatment. Chemoprevention, an innovative approach aimed at halting or reversing the neoplastic process before full malignancy, has emerged as a promising avenue for mitigating the impact of OPMD and OSCC. The pivotal role of chemopreventive strategies is underscored by the need for effective interventions that go beyond traditional therapies. In this regard, chemopreventive agents offer a unique opportunity to intercept disease progression by targeting the molecular pathways implicated in carcinogenesis. Natural compounds, such as curcumin, green tea polyphenols, and resveratrol, exhibit anti-inflammatory, antioxidant, and anti-cancer properties that could make them potential candidates for curtailing the transformation of OPMD to OSCC. Moreover, targeted therapies directed at specific molecular alterations hold promise in disrupting the signaling cascades driving OSCC growth. Immunomodulatory agents, like immune checkpoint inhibitors, are gaining attention for their potential to harness the body's immune response against early malignancies, thus impeding OSCC advancement. Additionally, nutritional interventions and topical formulations of chemopreventive agents offer localized strategies for preventing carcinogenesis in the oral cavity. The challenge lies in optimizing these strategies for efficacy, safety, and patient compliance. This review presents an up to date on the dynamic interplay between molecular insights, clinical interventions, and the broader goal of reducing the burden of oral malignancies. As research progresses, the synergy between early diagnosis, non-invasive biomarker identification, and chemopreventive therapy is poised to reshape the landscape of OPMD and OSCC management, offering a glimpse of a future where these diseases are no longer insurmountable challenges but rather preventable and manageable conditions.

Abstract
OBJECTIVE To investigate the association between the prevalence of cyclosporin A-induced gingival overgrowth and the expression of the epithelial-to-mesenchymal transition factors in the gingival tissues of renal transplant patients. BACKGROUND Gingival overgrowth (GO) is a frequent complication in organ transplant patients treated with the immunosuppressant cyclosporin A (CsA). The epithelial-to-mesenchymal transition (EMT) is considered a factor contributing to CsA-induced GO. However, current knowledge on this topic is sparse. METHODS Sixty-three renal transplant patients were divided into two groups according to the occurrence of GO: those with gingival overgrowth (GO+ group) and those without gingival overgrowth (GO- group). Data on age, sex, and use of immunosuppressant and calcium channel blocker medications, serum creatinine values, peak concentrations of blood CsA, and gingival hyperplasia scores were recorded to identify clinically pathogenic factors. Gingival tissues from five patients with CsA-induced GO and five healthy subjects were selected for histomorphological observation with hematoxylin-eosin staining, Masson staining, and immunohistochemical staining. The mRNA expression of EMT factors was detected with reverse transcription-quantitative PCR. RESULTS The use of CsA significantly increased the prevalence of GO in renal transplant patients. The expression of α-SMA, SMAD4, and TGM2 was upregulated and that of E-cadherin was downregulated in the gingival tissues of patients with CsA-induced GO compared with those of the corresponding controls. CONCLUSION Treatment with CsA is closely related to the occurrence of GO in renal transplant patients and EMT plays an important role in CsA-induced gingival tissue hyperplasia.

Abstract
Poly(ethylene terephthalate)-PET-is one of the most frequently used polymers in biomedical applications. Due to chemical inertness, PET surface modification is necessary to gain specific properties, making the polymer biocompatible. The aim of this paper is to characterize the multi-component films containing chitosan (Ch), phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), immunosuppressant cyclosporine A (CsA) and/or antioxidant lauryl gallate (LG) which can be utilized as a very attractive material for developing the PET coatings. Chitosan was employed owing to its antibacterial activity and also its ability to promote cell adhesion and proliferation favorable for tissue engineering and regeneration purposes. Moreover, the Ch film can be additionally modified with other substances of biological importance (DOPC, CsA and LG). The layers of varying compositions were prepared using the Langmuir-Blodgett (LB) technique on the air plasma-activated PET support. Then their nanostructure, molecular distribution, surface chemistry and wettability were determined by atomic force microscopy (AFM), time-of-flight secondary ion mass spectrometry (TOF-SIMS), X-ray photoelectron spectroscopy (XPS), contact angle (CA) measurements and the surface free energy and its components' determination, respectively. The obtained results show clearly the dependence of the surface properties of the films on the molar ratio of components and allow for a better understanding of the coating organization and mechanisms of interactions at the molecular level both inside the films and between the films and the polar/apolar liquids imitating the environment of different properties. The organized layers of this type can be helpful in gaining control over the surface properties of the biomaterial, thus getting rid of the limitations in favor of increased biocompatibility. This is a good basis for further investigations on the correlation of the immune system response to the presence of biomaterial and its physicochemical properties.

Abstract
Abstract
Calcium channel blockers, a group of drugs widely used in the treatment of cardiovascular patients, although effective, often cause gingival enlargement, a side effect that is rarely recognized in clinical practice and is not given sufficient importance. Gingival enlargement caused by calcium channel blockers can be localized or generalized, mild or severe. It can negatively affect patients’ appearance, mastication, and speech, thus considerably reducing the quality of life of patients. Risk factors and pathogenesis of this side effect have been the subject of many studies but are still unknown, making this condition a major therapeutic challenge, especially if the cessation of the offending drug is not possible. This study aimed to review the etiology, potential risk factors, pathogenesis, clinical features, and therapy possibilities for gingival enlargement caused by calcium channel blockers.

Abstract
The reason for the destruction of the attachment apparatus in patients with periodontal disease is the supra- and the subgingival microflora. Hence, the treatment of this inflammatory gingival disease is primarily focused on eliminating the cause. The present case report assessed the therapeutic benefit of adjunctive use of a commercially available topical agent containing 1% hyaluronic acid gel combined with nonsurgical periodontal therapy. A patient aged 64 years with type 2 diabetes mellitus reported to the Department of Periodontology. He complained of gum enlargement and frequent bleeding during brushing. The patient was not under any medication for his diabetes control. On examination, there was a localized papillary gingival enlargement. Therefore, Klirich gel containing hyaluronic acid was applied on the surface of the gingiva during the first visit of the patient. During the follow-up visit, he continued with this adjunctive use of the gel along with the nonsurgical periodontal therapy. In addition, he controlled his blood sugar level with diet and exercise. During the follow-up visit after one year, there was a noticeable clinical change in the overall health of his gingiva.
