Abstract
PURPOSE Investigate the content of fibrotic fibrils in gingival tissue and the proliferation of fibroblasts collected from recurrent and non-recurrent hereditary gingival fibromatosis (HGF) and idiopathic gingival fibromatosis (IGF). METHODS Gingival biopsies were collected from HGF (n = 3) and IGF (n = 3) donors with recurrent and non-recurrent gingival overgrowths and from a control group (Ctrl, n = 3). Hematoxylin staining was performed to evaluate the histomorphology of gingival tissue. Heidenhain's AZAN trichrome staining served for visualization of fibrotic fibrils in gingiva. Quantitative analysis of the content of fibrotic fibrils in gingival tissue was performed using a polarized light microscope. Proliferation was evaluated at 24 h, 48 h, and 72 h in fibroblast cultures using a cell proliferation ELISA assay based on 5-bromo-2'-deoxyuridine (BrdU). RESULTS Numerous blood vessels and fibroblasts were observed in recurrent overgrowths, whereas moderate blood vessels and moderate to scanty fibroblasts were detected in non-recurrent overgrowths. Heidenhain's staining revealed numerous collagen fibers in both recurrent and non-recurrent overgrowths. Quantitative analysis in a polarizing microscope showed significant accumulation of fibrotic fibrils exclusively in the overgrowths with the recurrence. In all time-points, increased proliferation of cells from all recurrent overgrowths was observed, but not from overgrowths which do not reoccur. CONCLUSIONS The study revealed that recurrent gingival overgrowths consist of highly fibrotic and dense connective tissue with numerous blood vessels and abundant fibroblasts. We also demonstrated that unlike fibroblasts derived from overgrowths, which did not present recurrence, fibroblasts derived from highly fibrotic and recurrent overgrowths maintain high rate of proliferation in vitro.

Analysis of mutations in the SOS-1 gene in two Polish families with hereditary gingival fibromatosis. Oral Dis 2017; 23:983-989. [PMID: 28425619 DOI: 10.1111/odi.12684] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Revised: 04/06/2017] [Accepted: 04/12/2017] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To establish whether two families from Malopolska and Mazovia provinces in Poland are affected by hereditary gingival fibromatosis type 1, caused by a single-cytosine insertion in exon 21 of the Son-of-Sevenless-1 gene. MATERIAL AND METHODS Six subjects with hereditary gingival fibromatosis and five healthy subjects were enrolled in the study. Gingival biopsies were collected during gingivectomy or tooth extraction and used for histopathological evaluation. Total RNA and genomic DNA were purified from cultured gingival fibroblasts followed by cDNA and genomic DNA sequencing and analysis. RESULTS Hereditary gingival fibromatosis was confirmed by periodontal examination, X-ray, and laboratory tests. Histopathological evaluation showed hyperplastic epithelium, numerous collagen bundles, and abundant-to-moderate fibroblasts in subepithelial and connective tissue. Sequencing of exons 19-22 of the Son-of-Sevenless-1 gene did not reveal a single-cytosine insertion nor other mutations. CONCLUSIONS Patients from two Polish families under study had not been affected by hereditary gingival fibromatosis type 1, caused by a single-cytosine insertion in exon 21 of the Son-of-Sevenless-1 gene. Further studies of the remaining regions of this gene as well as of other genes are needed to identify disease-related mutations in these patients. This will help to unravel the pathogenic mechanism of gingival overgrowth.

Abstract
Aim: To evaluate immunohistochemically vascular endothelial growth factor (VEGF) and Ki-67 in human gingival samples and to compare these factors between healthy and diabetic patients. Materials and Methods: A total of 50 subjects were included in the study. They were categorized into three groups: Periodontally healthy group, periodontally diseased gingiva without any systemic disease group and periodontally diseased gingiva with controlled type II diabetes mellitus (DM) group. Gingival biopsies were performed and immunohistochemical analysis were done for VEGF and Ki-67 staining in gingival samples. Results: The present study found moderate intensity staining for VEGF in periodontitis group and periodontitis with controlled type II DM group and mild intensity staining for VEGF in periodontally healthy group. With regard to Ki-67, negative staining was observed in periodontally healthy group and mild staining in periodontitis group and periodontitis with controlled type II DM group. Conclusion: Further investigation needs to be conducted to identify how VEGF and Ki-67 are involved in the tissue inflammation associated processes and the relationship between VEGF and Ki-67 in progression of periodontitis.

Abstract
Although non-syndromic hereditary gingival fibromatosis (HGF) is genetically heterogeneous, etiologic mutations have been identified only in the Son of Sevenless-1 gene (SOS1). To test evidence of increased cell proliferation, we studied histological, morphological, and proliferation characteristics in monolayer and three-dimensional cultures of fibroblasts with the SOS1 g.126,142-126,143insC mutation. Histological assessment of HGF gingiva indicated increased numbers of fibroblasts (30%) and increased collagen (10%). Cell proliferation studies demonstrated increased growth rates and 5-bromo-2-deoxyuridine incorporation for HGF fibroblasts. Flow cytometry showed greater proportions of HGF fibroblasts in the G2/M phase. Attachment of HGF fibroblasts to different extracellular matrix surfaces demonstrated increased formation of protrusions with lamellipodia. HGF fibroblasts in three-dimensional culture showed greater cell proliferation, higher cell density, and alteration of surrounding collagen matrix. These findings revealed that increased fibroblast numbers and collagen matrix changes are associated with mutation of the SOS1 gene in vitro and in vivo.

Abstract
Hereditary gingival fibromatosis (HGF) is characterized by the slowly progressive fibrous enlargement of gingival tissue. It usually develops as an isolated disorder but can also be one feature of various syndromes. The currently preferred terminology of these syndromes mainly describes the clinical features of the disorder without identifying the cause. In this report, we present the 5-year follow up of a family with HGF and features of 3 previously described syndromes: Jones syndrome, Zimmerman-Laband syndrome, and HGF-hypertrichosis syndrome. The 45-year-old father had HGF, hypertrichosis, hearing loss, and short stubby fingers and toes with hypoplasia of the terminal phalanges and hypoplasia of the nails on the thumbs. The features of 13-year-old son were almost identical to those of his father except for hypertrichosis, but in addition he was mentally retarded. Although the 10-day-old son had HGF and defective fingers, the mother and 7-year-old daughter were unaffected. Owing to the overlap of these syndromes, we argue that the identification of the genetic pathways and mechanisms will be the most important factor in classifying these disorders, with the phenotype playing a minor role.

Abstract
Generalized gingival enlargement can be caused by a variety of etiological factors. It can be inherited (hereditary gingival fibromatosis [HGF]); associated with other diseases characterizing a syndrome; or induced as a side effect of systemic drugs, such as phenytoin, cyclosporin, or nifedipine. HGF, previously known as elephantiasis gingivae, hereditary gingival hyperplasia, and hypertrophic gingiva, is a genetic disorder characterized by a progressive enlargement of the gingiva. This review will focus on diagnosis, treatment, and control of HGF. The pattern of inheritance, the histopathologic characteristics, and the known biologic and genetic features associated with HGF are also emphasized.
