Cancers (Basel) 2021; 14:cancers14010031. [PMID: 35008199 PMCID: PMC8750470 DOI: 10.3390/cancers14010031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 12/16/2021] [Accepted: 12/19/2021] [Indexed: 11/16/2022] Open
Abstract
Epstein-Barr virus (EBV) is associated with various types of human malignancies, including nasopharyngeal carcinoma (NPC), EBV-associated gastric carcinoma (EBVaGC), and oral squamous cell carcinoma (OSCC). The present study aimed to identify gene signatures and common signaling pathways that can be used to predict the prognosis of EBV-associated epithelial cancers (EBVaCAs) by performing an integrated bioinformatics analysis of cell lines and tumor tissues. We identified 12 differentially expressed genes (DEGs) in the EBVaCA cell lines. Among them, only four DEGs, including BAMBI, SLC26A9, SGPP2, and TMC8, were significantly upregulated. However, SLC26A9 and TMC8, but not BAMBI and SGPP2, were significantly upregulated in EBV-positive tumor tissues compared to EBV-negative tumor tissues. Next, we identified IL6/JAK/STAT3 and TNF-α/NF-κB signaling pathways as common hallmarks of EBVaCAs. The expression of key genes related to the two hallmarks was upregulated in both EBV-infected cell lines and EBV-positive tumor tissues. These results suggest that SLC26A9 and TMC8 might be gene signatures that can effectively predict the prognosis of EBVaCAs and provide new insights into the molecular mechanisms of EBV-driven epithelial cancers.

TMC8 mutation in a Turkish family with epidermodysplasia verruciformis including laryngeal papilloma and recurrent skin carcinoma. J Cosmet Dermatol 2021; 21:2263-2267. [PMID: 34416085 DOI: 10.1111/jocd.14393] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 08/01/2021] [Accepted: 08/10/2021] [Indexed: 12/01/2022]
Abstract
The vast majority of primary immunodeficiencies (PIDs) occur due to the defects in cells originating from hematopoietic stem cells, while in some PIDs, there are defects in various genes responsible for non-leucocyte immune response such as seen in epidermodysplasia verruciformis (EV). EV caused by the mutations in TMC6, TMC8, and CIB1 genes is called "typical." "Atypical" EV may develop in patients with primary immunodeficiencies originating from hematopoietic stem cells, which include severe T-cell failure, caused by inactivating biallelic mutations of STK4, RHOH, CORO1A, ITK, TPP2, DCLRE1C, LCK, RASGRP1, or DOCK8 genes. Here, we present a family with TMC8 gene mutation leading to disseminated epidermodysplasia verruciformis including laryngeal papilloma and recurrent cutaneous squamous cell carcinomas. Typical EV with impaired local, keratinocyte-intrinsic immune response should be considered when routine immunological examinations are normal in patients presenting with clinical signs of EV. Although it is not possible to prevent EV lesions, early and appropriate surveillance for malignancy is mandatory.

Abstract
BACKGROUND In this study, we aimed to investigate the biological functions of Transmembrane Channel-Like 5 (TMC5) by bioinformatics and molecular biology methods in prostate cancer (PCa). METHODS We assessed the mRNA expression level of TMC5 in PCa with public database the Cancer Genome Atlas (TCGA) and Oncomine. The biological functions were demonstrated by bioinformatics methods and siRNA mediated knockdown experiments. Reverse transcription polymerase chain reaction (RT-PCR), immunohistochemical (IHC) experiments and microarray analysis were performed to confirm the results. RESULTS TMC5 expression level was significantly up-regulated in 4 independent PCa cohorts compared to normal group. Moreover, TMC5 has higher diagnostic efficiency than PSA-KLK3 (AUC (Area Under Curve) = 0.772, P < 0.001). The high expression of TMC5 was associated with clinical Gleason score, prostate-specific antigen (PSA) level, androgen receptor (AR) activity score and the genes which were known frequently mutated in PCa progression (P < 0.05). Functionally, Gene Otology (GO) analysis suggested that TMC5 was related to cell development; TMC5 knockdown significantly inhibited PCa cells proliferation by arresting cell cycle at G1 phase. Drug sensitivity experiments showed TMC5 knockdown significantly enhanced cells sensitivity to 5-Fluorouracil. Microarray analysis showed TMC5 knockdown significantly inhibited cell cycle and tumor progression. CONCLUSION Our findings revealed that TMC5 promoted PCa cell proliferation through cell cycle regulation and could be a powerful and hopeful target for PCa treatment.

Abstract
Proper regulation of the immune system is required for protection against pathogens and preventing autoimmune disorders. Inborn errors of the immune system due to inherited or de novo germline mutations can lead to the loss of protective immunity, aberrant immune homeostasis, and the development of autoimmune disease, or combinations of these. Forward genetic screens involving clinical material from patients with primary immunodeficiencies (PIDs) can vary in severity from life-threatening disease affecting multiple cell types and organs to relatively mild disease with susceptibility to a limited range of pathogens or mild autoimmune conditions. As central mediators of innate and adaptive immune responses, T cells are critical orchestrators and effectors of the immune response. As such, several PIDs result from loss of or altered T cell function. PID-associated functional defects range from complete absence of T cell development to uncontrolled effector cell activation. Furthermore, the gene products of known PID causal genes are involved in diverse molecular pathways ranging from T cell receptor signaling to regulators of protein glycosylation. Identification of the molecular and biochemical cause of PIDs can not only guide the course of treatment for patients, but also inform our understanding of the basic biology behind T cell function. In this chapter, we review PIDs with known genetic causes that intrinsically affect T cell function with particular focus on perturbations of biochemical pathways.

Abstract
Our laboratory has developed bioinformatic strategies for identifying distant phylogenetic relationships and characterizing families and superfamilies of transport proteins. Results using these tools suggest that the Anoctamin Superfamily of cation and anion channels, as well as lipid scramblases, includes three functionally characterized families: the Anoctamin (ANO), Transmembrane Channel (TMC) and Ca2+-permeable Stress-gated Cation Channel (CSC) families; as well as four families of functionally uncharacterized proteins, which we refer to as the Anoctamin-like (ANO-L), Transmembrane Channel-like (TMC-L), and CSC-like (CSC-L1 and CSC-L2) families. We have constructed protein clusters and trees showing the relative relationships among the seven families. Topological analyses suggest that the members of these families have essentially the same topologies. Comparative examination of these homologous families provides insight into possible mechanisms of action, indicates the currently recognized organismal distributions of these proteins, and suggests drug design potential for the disease-related channel proteins.

Abstract
BACKGROUND Plasmacytoid dendritic cells (pDCs) are the most potent producers of type I interferons (IFNs), and are involved in the pathogenesis of several cutaneous infectious (especially viral), inflammatory/autoimmune and neoplastic entities. Their role in the pathogenesis and regression of human papilloma virus (HPV)-induced skin lesions has not been well studied. AIM To investigate pDC occurrence and activity in HPV-induced skin lesions, including inflamed and uninflamed warts as well as epidermodysplasia verruciformis (EDV)-associated lesions. METHODS In total 20 inflamed and 20 uninflamed HPV-induced skin lesions (including 7 EDV lesions) were retrieved from our database, and the tissue was immunohistochemically tested for pDC occurrence and activity using anti-BDCA-2 and anti-MxA antibodies, respectively. RESULTS pDCs were present in all 20 inflamed warts and absent from all 20 uninflamed cases. MxA expression was also diffuse and strong in 75% (15/20) inflamed warts, but not in any of the uninflamed warts. CONCLUSIONS pDCs constitute a central component of the inflammatory host response in inflamed warts, possibly contributing to their regression through production of type I interferons.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive malignant tumor and the third leading cause of cancer-related mortality worldwide. Transmembrane channel-like protein 8 (TMC8) is reported to play a major role in several aspects of human pathophysiology, such as ion channel permeability, human papillomavirus infection and skin cancer; however, its role in HCC has not been fully elucidated. The aim of the present study was to investigate the expression levels of TMC8 in 146 pairs of liver cancer samples and adjacent non-tumorous samples using immunohistochemistry. Reverse transcription-quantitative polymerase chain reaction analysis was used to confirm the results. The association between TMC8 expression and clinicopathological characteristics, including overall survival, was analyzed. The results indicated that the expression of TMC8 was significantly upregulated in HCC tissues and associated with metastasis and hepatitis B virus infection. According to the analysis of the overall survival using Cox proportional hazard regression model, higher expression of TMC8 was associated with a poorer prognosis and the overexpression of TMC8 was an independent risk factor for HCC. By contrast, HBsAg did not significantly affect the survival of HCC patients. These results suggest that the overexpression of TMC8 in HCC predicts poor prognosis and may be a potential biomarker for this type of cancer.

Abstract
Epidermodysplasia verruciformis (EV) is an uncommon inherited skin condition with increased vulnerability to widespread infection by certain human papillomavirus types, resulting in extensive verruca plana-like papules coalescing to large confluent plaques. Since the AIDS epidemic starting in the 1980s, an acquired type of EV has been described in patients infected with human immunodeficiency virus. The histopathologic features of EV consist of papillated epidermal hyperplasia with hypergranulosis and a distinct bluish-gray color in the large human papillomavirus-infected keratinocytes in the stratum granulosum. The authors present a case of HIV-associated EV with a unique histopathologic finding of multiple cornoid lamella-like structures. To the authors' knowledge, this finding has not been previously described in the literature.
