Abstract
Germline CYLD mutation is associated with the development of a rare inheritable syndrome, called the CYLD cutaneous syndrome. Patients with this syndrome are distinctly presented with multiple tumors in the head and neck region, which can grow in size and number over time. Some of these benign head and neck tumors can turn into malignancies in some individuals. CYLD has been identified to be the only tumor suppressor gene reported to be associated with this syndrome thus far. Here, we summarize all reported CYLD germline mutations associated with this syndrome, as well as the reported paired somatic CYLD mutations of the developed tumors. Interestingly, whole-exome sequencing (WES) studies of multiple cancer types also revealed CYLD mutations in many human malignancies, including head and neck cancers and several epithelial cancers. Currently, the role of CYLD mutations in head and neck carcinogenesis and other cancers is poorly defined. We hope that this timely review of recent findings on CYLD genetics and animal models for oncogenesis can provide important insights into the mechanism of head and neck tumorigenesis.

Abstract
Metastatic melanoma is an aggressive cancer with a poor prognostic, and the design of new targeted drugs to treat melanoma is a therapeutic challenge. A promising approach is to produce monoclonal antibodies (mAbs) against the endothelin B receptor (ETB), which is known to be overexpressed in melanoma and to contribute to proliferation, migration and vasculogenic mimicry associated with invasiveness of this cancer. We previously described rendomab-B1, a mAb produced by DNA immunization. It is endowed with remarkable characteristics in term of affinity, specificity and antagonist properties against human ETB expressed by the endothelial cells, but, surprisingly, had poor affinity for ETB expressed by melanoma cells. This characteristic strongly suggested the existence of a tumor-specific ETB form. In the study reported here, we identified a new mAb, rendomab-B4, which, in contrast to rendomab-B1, binds ETB expressed on UACC-257, WM-266-4 and SLM8 melanoma cells. Moreover, after binding to UACC-257 cells, rendomab-B4 is internalized and colocalizes with the endosomal protein EEA-1. Interestingly, rendomab-B4, despite its inability to compete with endothelin binding, is able to inhibit phospholipase C pathway and migration induced by endothelin. By contrast, rendomab-B4 fails to decrease ERK1/2 phosphorylation induced by endothelin, suggesting a biased effect on ETB. These particular properties make rendomab-B4 an interesting tool to analyze ETB-structure/function and a promising starting point for the development of new immunological tools in the field of melanoma therapeutics.

Pinho AC, Gouveia MJP, Gameiro ARP, Cardoso JCPS, Gonçalo MMM. Brooke-Spiegler Syndrome - an underrecognized cause of multiple familial scalp tumors: report of a new germline mutation. J Dermatol Case Rep 2015; 9:67-70. [PMID: 26512302 DOI: 10.3315/jdcr.2015.1208] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2015] [Accepted: 07/21/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND Brooke-Spiegler syndrome (BSS) is probably an underdiagnosed genodermatosis that predisposes for the development of cylindromas, spiradenomas and trichoepitheliomas mainly of the head and neck. Wide phenotypic variability regarding the number and type of lesions can be observed within a family. Mutations of the CYLD gene are identified in the vast majority of cases and play a key role in BSS pathogenesis. MAIN OBSERVATIONS Two first degree relatives with numerous erythematous telangiectatic nodules of the scalp present for decades, with recurring tendency regardless the multiple previous excisions. Histopathological review of the lesions revealed predominantly "spiradenocylindromas" in the proband and cylindromas in her sister. The suspicion of BSS was confirmed after detection of a new nonsense germline mutation of CYLD (c.1783C>T pGln 595*) in the proband. CONCLUSIONS BSS diagnosis can be challenging and is based on clinical-pathological correlation, positive familial association and identification of CYLD mutations. CYLD exerts antineoplastic effects by downregulating intracellular NF-κB signalling pathways. The reported mutation affecting the ubiquitin-specific protease domain leads to a truncated and catalytically inactive enzyme. Despite the expanding list of CYLD mutations no firm genotype-phenotype correlation is known so far. Early recognition and treatment of BSS avoid disfiguring changes like "turban tumor".

A novel CYLD germline mutation in Brooke-Spiegler syndrome. J Eur Acad Dermatol Venereol 2014; 29:457-62. [PMID: 25131725 DOI: 10.1111/jdv.12578] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2014] [Revised: 04/08/2014] [Accepted: 05/05/2014] [Indexed: 01/13/2023]
Abstract
BACKGROUND Brooke-Spiegler syndrome (BSS) is a rare, inherited, autosomal dominant disorder characterized by the development of multiple adnexal neoplasms including spiradenomas, cylindromas, trichoepitheliomas and major and minor salivary glands neoplasms. This syndrome encompasses a wide variability of clinical phenotypes depending on the variable number of tumours present in the given patient. OBJECTIVE Somatic mutations in adjunct to CYLD germline mutations may play a central role in the development of the tumour phenotype and in the genotype-phenotype correlations. METHODS Blood sample and paraffin embedded tissue biopsied from three cylindromas, one trichoepithelioma and one spiradenomas were collected after obtaining informed consent from our patient and genomic DNA was isolated. RESULTS We found out a novel germline mutation in the CYLD gene in exon 15 that resulted in the deletion of one nucleotide. This gives rise to a premature translational termination codon at amino acid position 693 prior to four Cys-X-X-Cys pairs and one of the two catalytic domains of ubiquitin carboxy-terminal hydrolases. In only one cylindroma we detected the same germline mutation (c.2070delT/p.F690FfsX3) in addition to two somatic events (I645V and R936X). The presence of this unique mutation could be linked to the peculiar phenotype of our patient who presented an attenuated form of BSS, an autosomal dominant inheritance with low penetrance and no additional visceral tumours. CONCLUSIONS The overall phenotype of our patient may support the hypothesis that somatic mutations in adjunct to CYLD germline mutations may play a central role in the development of the tumour phenotype and in the genotype-phenotype correlations.
