Abstract
Ameloblastoma is a rare human disease of benign neoplasm odontogenic tumor with a lower prevalence but higher recurrence rate. Etiology of ameloblastoma is not fully understood thus lacks implementation of curative treatments. One of the proposed models of evolution of ameloblastoma is related to alteration in DNA damage and repair effects. Growing body of literature has associated defect in DNA damage and repair mechanisms with cancer risk and various adverse health outcomes in humans. Persistent defect of repair and escape of these genomic unstable cells from cell death mechanisms can contribute towards accumulation of oncogene driver or tumor suppressor mutations selective for malignant transformations. In addition, growth, progression and survival of tumor depends upon its DNA repair mechanisms too, thus identifying a DNA repair biomarker can be of advantageous to eliminate the tumor. Understanding the interconnection of oral lesion and role of various DNA repair mechanisms in context to ameloblastoma will assist to build up a platform for translational based research. This study is a literature review of research work published up to date in the field of ameloblastoma in regard to DNA damage and repair effects.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2019; 121:146-149. [PMID: 31336213 DOI: 10.1016/j.jormas.2019.07.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 07/12/2019] [Accepted: 07/15/2019] [Indexed: 01/20/2023]
Abstract
Odontogenic lesions have been described in several syndromes. Despite multiple reports of ameloblastoma's association with various syndromes, it has not been added to the diagnostic criteria for any syndrome. Thus, the aim of this systematic review was gathering such cases' data. An electronic search in PubMed Central's database was performed. The search strategy was limited to human studies (case reports and case series), full-text English articles published from first of January 1975 until the end of 2018. Irrelevant articles or articles with inadequate information were omitted. Associated syndrome, patients' age and sex, lesions' location, radiographic features, and treatment modality were collected and analyzed. Ameloblastoma was reported in association with Gorlin syndrome (6 cases), epidermal nevus syndrome (2 cases), Gardner syndrome (2 cases), Simpson-Golabi-Behmel syndrome (1 case), and Williams syndrome (1 case). The commonest associated syndrome was Gorlin syndrome (50%) with maxillary and female predilections. Both cases of epidermal nevus syndrome (ENS) were female with mandibular involvement. In syndromes that odontogenic lesions are one of the diagnostic criteria, it is important to rule out ameloblastic changes. Although the relationship between ameloblastoma and these syndromes is not well known, any related information may be helpful in understanding the pathogenesis and the nature of this neoplasm.

Nevoid Basal Cell Carcinoma Syndrome: PTCH1 Mutation Profile and Expression of Genes Involved in the Hedgehog Pathway in Argentinian Patients. Cells 2019; 8:cells8020144. [PMID: 30754660 PMCID: PMC6406887 DOI: 10.3390/cells8020144] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2018] [Revised: 01/25/2019] [Accepted: 02/02/2019] [Indexed: 12/23/2022] Open
Abstract
Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder characterized by multiple basal cell carcinomas (BCC), mainly caused by PTCH1 gene mutations. Our current study aimed to establish (1) PTCH1 germinal and somatic mutational status, (2) component and Hedgehog (HH) pathway targets gene expression patterns, and (3) profile variations according to the genetic background in BCC and normal surrounding skin (NSS). We collected 23 blood and 20 BCC patient samples and analyzed the PTCH1 gene using bidirectional sequencing and multiplex ligation-dependent probe amplification. Quantitative PCR was used to determine the mRNA expression levels of PTCH1, SMO, GLI3, and CCND1 in paired samples of BCC and NSS from 20 patients and four non-NBCCS skin controls (C). Our analyses identified 12 germline and five somatic sequence variants in PTCH1. mRNA levels of PTCH1, SMO, and GLI3 were higher in NSS compared to C samples, reaching maximum values in BCC samples (p < 0.05). NSS with PTCH1 germline mutations had modified SMO, PTCH1, and GLI3 mRNA levels compared to samples without mutation (p < 0.01). Two PTCH1 mutations in BCC led to an increase in PTCH1, SMO, and GLI3, and a decrease in CCND1 mRNA levels (p < 0.01 vs. BCC with germline mutation only). These results indicate that besides PTCH1, other genes are responsible for NBCCS and BCC development in a population exposed to high UV radiation. Additionally, the mutational events caused increased expression of HH-related genes, even in phenotypically normal skin.

Abstract
Numerous familial tumor syndromes are associated with distinctive oral mucosal findings, which may make possible an early diagnosis as an efficacious marker for the risk of developing visceral malignancies. In detail, Familial Adenomatous Polyposis (FAP), Gardner syndrome, Peutz-Jeghers syndrome, Cowden Syndrome, Gorlin Syndrome, Lynch/Muir-Torre Syndrome and Multiple Endocrine Neoplasia show specific lesions of the oral mucosa and other distinct clinical and molecular features. The common genetic background of the above mentioned syndromes involve germline mutations in tumor suppressor genes, such as APC, PTEN, PTCH1, STK11, RET, clearly implied in both ectodermal and mesodermal differentiation, being the oral mucosal and dental stigmata frequently associated in the specific clinical phenotypes. The oral and maxillofacial manifestations of these syndromes may become visible several years before the intestinal lesions, constituting a clinical marker that is predictive for the development of intestinal polyps and/or other visceral malignancies. A multidisciplinary approach is therefore necessary for both clinical diagnosis and management of the gene-carriers probands and their family members who have to be referred for genetic testing or have to be investigated for the presence of visceral cancers.

Abstract
There are several genetic diseases with a wide spectrum of congenital bone stigmata in association to cutaneous and visceral benign and malignant neoplasms. Gorlin-Goltz syndrome, also named nevoid basal cell carcinoma syndrome, is an autosomal dominant systemic disease with almost complete penetrance and high intra-familial phenotypic variability, caused by germline mutations of the gene PTCH1. The syndrome is characterized by unusual skeletal changes and high predisposition to the development of multiple basal cell carcinomas, odontogenic keratocysts tumors and other visceral tumors. The Gorlin syndrome, clinically defined as distinct syndrome in 1963, existed during Dynastic Egyptian times, as revealed by a costellation of skeletal findings compatible with the syndrome in mummies dating back to 3000years ago and, most likely, in the ancient population of Pompeii. These paleogenetic and historical evidences, together with the clinical and biomolecular modern evidences, confirm the quite benign behavior of the syndrome and the critical value of the multiple and synchronous skeletal anomalies in the recognition of these rare and complex genetic disease.

Abstract
BACKGROUND Sonic hedgehog (SHH) pathway activation has been identified as a key factor in the development of many types of tumors, including odontogenic tumors. Our study examined the expression of genes in the SHH pathway to characterize their roles in the pathogenesis of keratocystic odontogenic tumors (KOT) and ameloblastomas (AB). METHODS We quantified the expression of SHH, SMO, PTCH1, SUFU, GLI1, CCND1, and BCL2 genes by qPCR in a total of 23 KOT, 11 AB, and three non-neoplastic oral mucosa (NNM). We also measured the expression of proteins related to this pathway (CCND1 and BCL2) by immunohistochemistry. RESULTS We observed overexpression of SMO, PTCH1, GLI1, and CCND1 genes in both KOT (23/23) and AB (11/11). However, we did not detect expression of the SHH gene in 21/23 KOT and 10/11 AB tumors. Low levels of the SUFU gene were expressed in KOT (P = 0.0199) and AB (P = 0.0127) relative to the NNM. Recurrent KOT exhibited high levels of SMO (P = 0.035), PTCH1 (P = 0.048), CCND1 (P = 0.048), and BCL2 (P = 0.045) transcripts. Using immunolabeling of CCND1, we observed no statistical difference between primary and recurrent KOT (P = 0.8815), sporadic and NBCCS-KOT (P = 0.7688), and unicystic and solid AB (P = 0.7521). CONCLUSIONS Overexpression of upstream (PTCH1 and SMO) and downstream (GLI1, CCND1 and BCL2) genes in the SHH pathway leads to the constitutive activation of this pathway in KOT and AB and may suggest a mechanism for the development of these types of tumors.

Abstract
Peripheral ameloblastoma (PA) in gingiva is rare and often confused with oral basal cell carcinoma (OBCC). The tissues of one case of PA and one case of OBCC with the same mandibular molar area affected were compared via an immunohistochemical examination using 50 antisera. The PA and OBCC showed similar proliferation of basaloid epithelial strands, but toluidine blue staining revealed that the PA had pinkish juxta-epithelial myxoid tissue, whereas the OBCC was infiltrated by many mast cells. Immunohistochemical comparisons showed that the PA was strongly positive for ameloblastin, KL1, p63, carcinoembryonic antigen, focal adhesion kinase, and cathepsin K, and slightly positive for amelogenin, Krox-25, E-cadherin, and PTCH1, whereas the OBCC was not. On the other hand, the OBCC was strongly positive for EpCam, matrix metalloprotease (MMP)-1, α1-antitrypsin, cytokeratin-7, p53, survivin, pAKT1, transforming growth factor-β1, NRAS, TGase-1, and tumor nescrosis factor-α, and consistently positive for β-catenin, MMP-2, cathepsin G, TGase-2, SOS-1, sonic hedgehog, and the β-defensins-1, -2, -3, while the PA was not. These data suggest that the tumorigeneses of PA and OBCC differ, and that PAs undergo odontogenic differentiation and generate oncogenic signals for infiltrative growth and bone resorption, whereas OBCCs undergo basaloid epidermal differentiation as a result of growth factor/cytokine-related oncogenic signals.

Abstract
Ameloblastomas are considered to be aggressive and locally invasive neoplasms derived from odontogenic epithelium with a tendency for recurrence and bone destruction. Although the relationship between nevoid basal cell carcinoma syndrome (NBCCS) and ameloblastoma is less frequent, it might constitute a peculiar stigmata of this hereditary disorder. The objective of the current study was to evaluate whether a combined clinical and biomolecular approach could be useful for the identification of NBCCS among patients with a diagnosis of ameloblastoma. The authors collected ameloblastoma tumors recorded in the databases of the Pathology Departments of the University of Modena during the period 1991-2011. Family trees were drawn for all 41 patients affected by these specific odontogenic tumors. Two patients with ameloblastoma were also affected by multiple basal cell carcinomas and odontogenic keratocysts tumors (OKCTs) achieving the requested clinical criteria for the diagnosis of NBCCS. The clinical diagnoses were confirmed by the identification of two different novel PTCH1 germline mutations (c.2186A > T [p.K729 M]; c.931insA) in those unrelated patients. Clinical ameloblastoma findings can be used as screening for the identification of families at risk of NBCCS. Ameloblastomas diagnosis warrants the search for associated cutaneous basal cell carcinomas and other benign and malignant tumors related to NBCCS. Thus, we propose the inclusion of ameloblasoma as criterion for the identification of NBCCS.

Abstract
Keratocystic odontogenic tumors (KCOTs) are cystic tumors that arise sporadically or associated with nevoid basal cell carcinoma syndrome (NBCCS). NBCCS is a rare autosomal dominantly inherited disease mainly characterized by multiple basal cell carcinomas, KCOTs of the jaws and a variety of other tumors. PTCH1 mutation can be found both in sporadic or NBCCS associated KCOTs. The aim of the current study was to assess whether a combined clinical and bio-molecular approach could be suitable for the detection of NBCCS among patients with a diagnosis of keratocystic odontogenic tumors (KCOTs). The authors collected keratocystic odontogenic tumors recorded in the database of the Pathology Department of the University of Modena and Reggio Emilia during the period 1991–2011. Through interviews and examinations, family pedigrees were drawn for all patients affected by these odontogenic lesions. We found out that 18 of the 70 patients with KCOTs and/or multiple basal cell carcinomas actually met the clinical criteria for the diagnosis of NBCCS. A wide inter- and intra-familial phenotypic variability was evident in the families. Ameloblastomas (AMLs) were reported in two probands that are also carriers of the PCTH1 germline mutations. Nine germline mutations in the PTCH1 gene, 5 of them novel, were evident in 14 tested probands. The clinical evaluation of the keratocystic odontogenic tumors can be used as screening for the detection of families at risk of NBCCS. Keratocystic odontogenic lesions are uncommon, and their discovery deserves the search for associated cutaneous basal cell carcinomas and other benign and malignant tumors related to NBCCS.
