Abstract
Objective This study aimed to explore genetic variations associated with DNA repair mechanisms to enhance the management of both oral cancer (OC) and oral precancer (OPC). Methods A cohort of 380 patients diagnosed with OC and OPC, comprising 220 males and 160 females, was analyzed. Participants were categorized based on their tobacco-chewing habits, with corresponding control groups established. Key genetic markers investigated for polymorphisms included OGG1, APE1, and XRCC1. Results The XRCC1 Arg280H variant demonstrated significant associations with the susceptibility to both OC and OPC across various models. Further analyses, incorporating factors such as tobacco and alcohol consumption, unveiled a correlation between the XRCC1 Arg194Trp variant and an elevated risk of developing head and neck cancer. Stratified analyses also revealed an increased risk of OC or OPC based on the specific site of the cancer. Conclusion The study underscores the importance of XRCC1 polymorphisms, particularly XRCC1 Arg280H and XRCC1 Arg194Trp, within the genetic framework of OC and OPC. Understanding these genetic associations provides valuable insights for the potential development of targeted interventions aimed at individuals predisposed to these conditions.

Abstract
Nuclear expression of β-catenin has been reported in canine intestinal epithelial tumors (IETs) and colorectal inflammatory polyps (CIPs) with dysplastic epithelia. However, the role of the Wnt/β-catenin signaling pathway in these lesions remains unclear. To investigate the association between the nuclear β-catenin expression and the activation of the Wnt/β-catenin signaling pathway, immunohistochemistry and mutation analyses were conducted on 64 IETs and 20 CIPs. IETs and CIPs with β-catenin nuclear and/or cytoplasm immunolabeling were classified as β-catenin (+). The immunostaining scores of c-Myc and Cyclin D1 and Ki-67 index were significantly higher in β-catenin (+) cases than in β-catenin (-) cases. Identical APC mutations (p.E154D and p.K155X) were detected in 6/41 β-catenin (+) IETs; all 6 of IETs with APC mutations were Jack Russell Terriers. CTNNB1 mutations were detected in 29/42 β-catenin (+) IETs, 3/11 β-catenin (+) CIPs, and 2/22 β-catenin (-) IETs, most of which were hotspots associated with human colorectal carcinoma. In one Miniature Dachshund diagnosed with a CIP that subsequently developed into an IET, the same CTNNB1 mutation was detected in both lesions. The immunohistochemical results suggest that cell proliferative activity in β-catenin (+) cases may be associated with activation of the Wnt/β-catenin signaling pathway. The mutation analysis results suggest that CTNNB1 mutations may be associated with cytoplasmic β-catenin accumulation in IET and CIP. Furthermore, the dysplastic epithelium in CIP may progress to IET through the activation of the Wnt/β-catenin signaling pathway by the CTNNB1 mutation.

First Evidence of Familial Transmission of Hereditary Gastrointestinal Polyposis Associated with Germline APC Variant in Jack Russell Terriers. Vet Sci 2023; 10:439. [PMID: 37505844 PMCID: PMC10385476 DOI: 10.3390/vetsci10070439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/01/2023] [Accepted: 07/03/2023] [Indexed: 07/29/2023] Open
Abstract
Jack Russell terriers (JRTs) with gastrointestinal (GI) neoplastic polyps have been recently reported to harbor an identical germline variant in the adenomatous polyposis coli (APC) gene, c.[462_463delinsTT], in the heterozygous state, which indicates that this disease is an autosomal dominant hereditary disorder. Many individual cases of this disease have been observed in clinical practice; however, familial transmission has not been demonstrated due to the difficulty in tracing the family members of household dogs, especially after the disease's onset in adulthood. Recently, we encountered two cases of GI polyposis in maternal half sisters. These two cases facilitated the identification of additional relatives spanning three generations, including parents, full and half siblings of the dam (aunt and uncle), littermate and non-littermate siblings, and a nephew. Genetic analysis revealed that 11 of the 14 examined JRTs in this family carried the heterozygous germline APC variant, and eight dogs with the variant already had a current and/or past medical history of GI neoplastic polyps. Some cases in the family showed significantly more severe disease phenotypes than those initially reported, suggesting that the severity of this disease can vary considerably among individuals. Moreover, familial aggregation of severe cases suggested that the genetic modifier involved in increasing severity may have been transmitted in this family in addition to the germline APC variant. Furthermore, in addition to this family, we reported two other families of JRTs affected by hereditary GI polyposis that consisted of five full and half siblings and a mother-daughter pair, respectively. These findings unequivocally establish the transgenerational transmission of hereditary GI polyposis associated with the germline APC variant in JRT lineages.

Abstract
Simple Summary In dogs, hundreds of hereditary diseases are currently known, representing a major health problem in small animal clinical practice. Hereditary gastrointestinal (GI) polyposis in Jack Russell Terriers (JRTs) is a hereditary disease recently discovered in Japan. This is an autosomal dominant disease caused by a germline variant in the adenomatous polyposis coli (APC) gene. Dogs with hereditary GI polyposis develop solitary and multiple tumors predominantly in the stomach and/or colorectum but have a much better prognosis than sporadic cases of GI tumors. Since the discovery of this disease, the number of newly diagnosed cases in Japan has increased, allowing the update of the disease’s clinical and pathological features. In the present study, some patients exhibited more severe condition than previously reported, including cases harboring tumors in the small intestine besides the stomach and colorectum. In addition, the rare cases died from systemic metastasis of GI tumors. Our study would facilitate the accurate diagnosis of hereditary GI polyposis in JRTs and raise global awareness of this novel hereditary disease. Abstract Hereditary GI polyposis in JRTs is a novel hereditary disease characterized by the development of solitary and multiple polypoid tumors, predominantly in the stomach and/or colorectum. Our recent study indicated that JRTs with GI neoplastic polyps harbor an identical germline variant in the APC gene, c.[462_463delinsTT], in a heterozygous state. Unlike sporadic cases, dogs afflicted with hereditary GI polyposis can be expected to have a prolonged survival time, as hereditary tumors are noninvasive. Since the discovery of this disease, the number of newly diagnosed cases in Japan has increased, allowing us to update the clinical and pathological features and provide a large number of diagnostic images. The present clinical case series study employing various diagnostic imaging techniques revealed that some of the cases harbored tumors in the small intestine in addition to the stomach and colorectum. Moreover, although rare, hereditary GI cancers can progress to the advanced stage and develop systemic metastasis, similar to sporadic GI tumors. These findings indicate that there is a wider range of variation in disease severity than was initially recognized. Our results can contribute to the accurate diagnosis of hereditary GI polyposis in clinical practice, pathological examinations, and future research.

Molecular epidemiological study of germline APC variant associated with hereditary gastrointestinal polyposis in dogs: current frequency in Jack Russell Terriers in Japan and breed distribution. BMC Vet Res 2022; 18:230. [PMID: 35717217 PMCID: PMC9206296 DOI: 10.1186/s12917-022-03338-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 06/10/2022] [Indexed: 11/25/2022] Open
Abstract
Background Cases of gastrointestinal (GI) neoplastic polyps in Jack Russell Terriers (JRTs) have increased in Japan since the late 2000s. We recently demonstrated that JRTs with GI polyps heterozygously harbor an identical germline variant in the adenomatous polyposis coli (APC) gene, c.[462_463delinsTT]; therefore, this is an autosomal dominant hereditary disease. We conducted a molecular epidemiological study to explore the current frequency of the APC variant in JRTs in Japan and the breed distribution of this disease. Results Peripheral blood samples from 792 JRTs were collected at 93 veterinary hospitals in Japan in 2020. Using an established polymerase chain reaction-restriction fragment length polymorphism assay, the germline APC variant was detected in 15 JRTs, with an overall frequency of 1.89%. The frequency was not significantly different for sex, age, and coat type criteria. Notably, the variant carriers had a current or previous history of GI neoplastic polyps, providing further evidence of the association of the germline APC variant with GI polyposis. Pedigree analysis of carrier dogs revealed that the germline APC variant was no longer confined to a few specific families but was widely spread among JRTs in Japan. Furthermore, some ancestors of the carriers were from Australia or New Zealand, suggesting the possible presence of carriers in countries other than Japan. Next, we retrospectively investigated the germline APC variant status of dogs with GI epithelial tumors using genomic DNA samples extracted from archived pathological specimens (28 purebred dogs of 14 breeds and four mixed-breed dog), as well as those stored in a canine genome bank (38 dogs of 18 breeds and a mixed-breed dogs). In total, 66 purebred dogs of 25 breeds, including another four JRTs, and five mixed-breed dogs were examined. While three variant carriers were found in JRTs, the germline APC variant was not detected in any of the other breeds. Conclusion The current frequency of the germline APC variant was approximately 2% in JRTs in Japan and the frequency remained roughly flat during the last 15 years. In addition, hereditary GI polyposis associated with the variant was virtually specific to JRTs.
