Abstract
Viruses have threatened animal and human lives since a long time ago all over the world. Some of these tiny particles have caused disastrous pandemics that killed a large number of people with subsequent economic downturns. In addition, the quarantine situation itself encounters the challenges like the deficiency in the online educational system, psychiatric problems and poor international relations. Although viruses have a rather simple protein structure, they have structural heterogeneity with a high tendency to mutation that impedes their study. On top of the breadth of such worldwide worrying issues, there are profound scientific gaps, and several unanswered questions, like lack of vaccines or antivirals to combat these pathogens. Various detection techniques like the nucleic acid test, immunoassay, and microscopy have been developed; however, there is a tradeoff between their advantages and disadvantages like safety in sample collecting, invasiveness, sensitivity, response time, etc. One of the highly resolved techniques that can provide early-stage detection with fast experiment duration is plasmonics. This optical technique has the capability to detect viral proteins and genomes at the early stage via highly sensitive interaction between the biological target and the plasmonic chip. The efficiency of this technique could be proved using commercialized techniques like reverse transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA) techniques. In this study, we aim to review the role of plasmonic technique in the detection of 11 deadliest viruses besides 2 common genital viruses for the human being. This is a rapidly moving topic of research, and a review article that encompasses the current findings may be useful for guiding strategies to deal with the pandemics. By investigating the potential aspects of this technique, we hope that this study could open new avenues toward the application of point-of-care techniques for virus detection at early stage that may inhibit the progressively hygienic threats.

Abstract
Nonmelanoma skin cancer (NMSC) has a greatly increased incidence among the immunosuppressed and the DNA of human papillomavirus (HPV) is commonly found in these tumors. To investigate if there are any actively transcribed HPV infections in these tumors, we identified all skin cancers diagnosed after solid organ transplantation in Sweden during 1964-2011 (n = 7614 NMSCs) and requested the diagnostic tumor blocks from the corresponding pathology archives. For the present study, we selected diagnostic specimens from 345 NMSC and performed whole genome transcriptome analysis using NovaSeq (Illumina), in comparison with three cervical cancers. Although we obtained an abundance of high-quality paired reads per sample (median of 35 million reads), only 15 NMSC specimens contained HPV transcription. Three specimens had transcription of oncogenic anogenital HPVs (HPV16 and 56), six tumors had transcription of HPVs from the beta-2 species (three HPV38, two with HPV23 and one with HPV107) and then there was one observation each of transcription of HPVs 3, 26, 57, 147, 158, 168 and of two nonestablished HPV types belonging to the gamma genus. In conclusion, transcription of specific HPV types can be found in NMSC among the immunosuppressed, but this is not common.

Abstract
Asian population is a low-risk group for basal cell carcinoma (BCC) and there is little data available in this setting. Sun-exposed BCC (SEBCC) may possess a different pathogenic mechanism from non-sun-exposed BCC (NSEBCC). To compare the histopathological profiles and outcomes between SEBCC and NSEBCC, and to assess the risk factors for tumor recurrences. Retrospective cohort study on 372 patients with pathologically diagnosed BCC from January 1, 1990 to August 31, 2017. Data were derived from a single medical center in Taiwan. SEBCC presented with higher Clark level and more high-risk factors for recurrence than NSEBCC. Nodular, micronodular, infiltrating/mixed infiltrating, basosquamous, and adenoid types were predominant in SEBCC, as superficial type in NSEBCC. Risk factors for recurrence included infiltrating/mixed-infiltrating subtypes and synchronous basosquamous cell carcinoma. No recurrence events were observed in NSEBCC. Our study showed an acceptable recurrence rate (4.2%) of the whole population after excision even under a smaller surgical margin width than suggested by current guidelines. SEBCC had a higher recurrence rate with a significantly different tumor characteristic from NSEBCC and a greater tumor depth than NSEBCC. A wider surgical margin in SEBCC than NSEBCC is suggested.

Abstract
Human papillomavirus (HPV) can cause various diseases; low-risk strains can cause
genital warts, whereas high-risk strains can cause cervical cancer and cancer of
the vulva in women and cancers of the penis, anus, and oropharynx in men.
Although HPV affects men, literature has reported that the prevalence of HPV
vaccination is far lower among men than among women. Few studies have examined
perceptions and acceptability of the HPV vaccine among men, particularly in
Chinese communities. In this study, the acceptability of the HPV vaccine to men
was investigated using Hong Kong men as a case group. A qualitative research
approach was adopted. Thirty-nine men were purposively sampled for the in-depth
individual semistructured interviews from June to October 2017 to investigate
their perceptions of the HPV vaccine and the barriers for them to receive the
vaccination. Limited knowledge and awareness of HPV-related issues, low
perceived risk of HPV infection, perceived association between HPV vaccine and
promiscuity, and lack of accessible official information on HPV-related topics
were identified as the key barriers. These barriers intermingled with the
sociocultural environment, cultural values of sexuality, and patriarchal gender
values. HPV vaccine is shown to be socially constructed as a vaccine for women
exclusively and for promiscuity. The participants were discouraged from
receiving HPV vaccination because of its signaling of socially deviant
promiscuity. Cultural taboo on sex served as a social oppression of open
discussion about HPV vaccine and affected the participants’ perceived need of
vaccination. Perceived insignificance of reproductive organs also influenced the
participants’ perceived need of vaccination.

Abstract
BACKGROUND Although more than 95% of viral sequences found in skin tumors typically belong to human papillomaviruses (HPVs), HPV transcription has so far not been detected. As current technology allows very deep transcriptome sequencing, we examined skin tumors and precursor lesions for HPV transcription. METHOD Fresh frozen biopsies from 12 skin specimens (11/12 were positive for HPV DNA) were subjected to total RNA sequencing. The cervical cancer cell line CaSki was included as a positive control for HPV transcription. RESULTS HPV RNA was detected and confirmed in 1/12 skin lesions at a median depth of 66 million reads per sample. One specimen was positive for HPV 110 transcripts mapping to E6, E7, E2/E4 and L2 open reading frames, as well as to a spliced E1^E4 transcript. CONCLUSION In conclusion, the study revealed that a minority of skin lesions contains HPV transcripts and that HPV DNA detection does not predict HPV transcriptional activity.

Abstract
A role for the beta genus HPVs in keratinocyte carcinoma (KC) remains to be established. In this article we examine the potential role of the beta HPVs in cancer revealed by the epidemiology associating these viruses with KC and supported by oncogenic properties of the beta HPV proteins. Unlike the cancer associated alpha genus HPVs, in which transcriptionally active viral genomes are invariably found associated with the cancers, that is not the case for the beta genus HPVs and keratinocyte carcinomas. Thus a role for the beta HPVs in KC would necessarily be in the carcinogenesis initiation and not in the maintenance of the tumor.

Abstract
According to the European Union Tissues and Cells Directives donation of tissue is contraindicated in the presence of or a previous history of malignant disease, with the exception of cutaneous basal cell carcinoma. Skin cancer is the most common cancer. Due to ultraviolet light exposure and increasing life expectancy an increasing prevalence of malignant or premalignant skin lesions is observed, which may result in a decline of the availability of skin for transplantation. A risk assessment based on published studies and expert opinion was performed in order to investigate the risk of transmitting malignant or premalignant skin lesions through tissue transplantation, and more particular through skin transplantation. The scarcity of data concerning cancer transmission in tissue transplantation was challenging. Circumstantial evidence, available for organ transplantation, was used to develop the following policy proposal for skin transplantation and cutaneous tumours. Malignant melanoma is an absolute contraindication for the donation of skin and also of other tissues, whereas, non-lesional skin and other tissues of a donor with non-melanoma skin cancer (basal cell and squamous cell carcinoma) or with a premalignant skin lesion can be considered for transplantation. The above mentioned protocol proposal might serve as a prototype for analogous protocols for non-cutaneous malignancies.

Abstract
Nearly 200 distinct human papilloma viruses (HPVs) have now been recognized, and each is associated with a specific set of clinical lesions. They are associated with a spectrum of diseases, from benign verrucae vulgares and condylomata acuminata to the malignancies of the cervix, vulva, anus, and penis. Disease associated with HPV can be divided into skin and mucosal lesion of the genital and extragenital regions. The relationship between HPV and nonmelanoma skin cancer (NMSC) is important clinically, because NMSC is the most common form of malignancy among fair-skinned populations. HPVs have also been detected in skin tags, lichen sclerosus, seborrheic keratoses, actinic keratoses, epidermal cysts, psoriatic plaques, and plucked hairs, but cutaneous HPV can be found on healthy skin.

Abstract
Beta-human papillomaviruses (β-HPV) infect cutaneous epithelia, and accumulating evidence suggests that the virus may act as a co-factor with UV-induced DNA damage in the development and progression of non-melanoma skin cancer, although the molecular mechanisms involved are poorly understood. The E6 protein of cutaneous β-HPV types encodes functions consistent with a role in tumorigenesis, and E6 expression can result in papilloma formation in transgenic animals. The E6 proteins of high-risk α-HPV types, which are associated with the development of anogenital cancers, have a conserved 4 aa motif at their extreme C terminus that binds to specific PDZ domain-containing proteins to promote cell invasion. Likewise, the high-risk β-HPVs HPV5 and HPV8 E6 proteins also share a conserved C-terminal motif, but this is markedly different from that of α-HPV types, implying functional differences. Using binding and functional studies, we have shown that β-HPV E6 proteins target β1-integrin using this C-terminal motif. E6 expression reduced membrane localization of β1-integrin, but increased overall levels of β1-integrin protein and its downstream effector focal adhesion kinase in human keratinocytes. Altered β1-integrin localization due to E6 expression was associated with actin cytoskeleton rearrangement and increased cell migration that was abolished by point mutations in the C-terminal motif of E6. We concluded that modulation of β1-integrin signalling by E6 proteins may contribute towards the pathogenicity of these β-HPV types.

Abstract
Systematic reviews of the prevalence of different types of Human Papillomavirus (HPV) across a broad range of disease grades from normal to cancer are essential to gain basic knowledge of how widespread infections with the different HPV types are, and to provide information on the possible carcinogenicity of different HPV types. For HPV types that infect human mucosa, of which 12 are established causes of cervical cancer, we present the results of a systematic review and meta-analysis of 47 HPV types in cervical samples across the entire range of cervical diagnoses from normal to cervical cancer, restricted to studies using a number of well characterized PCR assays. For the cutaneous HPV types, which have been linked to the development of squamous cell carcinoma of the skin, their presence has been measured in a variety of different sample types and by assays with variable performance. Therefore, we restricted a systematic review of their prevalence to studies that assayed for cutaneous HPV infection in a case-control format.

Abstract
To assess presence of virus DNA in skin lesions, swab samples from 82 squamous cell carcinomas of the skin (SCCs), 60 actinic keratoses (AKs), paraffin-embedded biopsies from 28 SCCs and 72 kerathoacanthomas (KAs) and fresh-frozen biopsies from 92 KAs, 85 SCCs and 92 AKs were analyzed by high throughput sequencing (HTS) using 454 or Ion Torrent technology. We found total of 4,284 viral reads, out of which 4,168 were Human Papillomavirus (HPV)-related, belonging to 15 known (HPV8, HPV12, HPV20, HPV36, HPV38, HPV45, HPV57, HPV59, HPV104, HPV105, HPV107, HPV109, HPV124, HPV138, HPV147), four previously described putative (HPV 915 F 06 007 FD1, FA73, FA101, SE42) and two putatively new HPV types (SE46, SE47). SE42 was cloned, sequenced, designated as HPV155 and found to have 76% similarity to the most closely related known HPV type. In conclusion, an unbiased approach for viral DNA detection in skin tumors has found that, although some new putative HPVs were found, known HPV types constituted most of the viral DNA.

Abstract
One-third of the cases of oropharyngeal squamous cell carcinoma (OSCC) contain oncogenic human papillomavirus (HR-HPV). Epidemiologic and molecular evidence underlines the causal role of HR-HPV in these tumors, which can be defined as HPV-related OSCC. These tumors differ from chemical/toxin-induced OSCC in several biological aspects, including specific molecular and genetic alterations. This leads to a characteristic clinical profile of HPV-related OSCC. Sexual risk factors play a role; however, the knowledge about natural infection and the rate of persistence of HR-HPV in the oropharynx is marginal. It is shown that the distinct biological behavior of the HPV-related subset of oropharyngeal tumors results in a more favorable prognosis. This might be the result of a better response to chemotherapy and radiotherapy. However, further studies are needed to show whether it will be possible to reliably select patients for individualized therapy depended on the HPV status of their tumors. Therefore, we think it will be mandatory to consider and stratify HPV status in the design of prospective clinical trials in the future.

Abstract
Recent studies have suggested an association between human papillomaviruses (HPVs), particularly species 2 members of the genus Betapapillomavirus, and squamous cell carcinoma (SCC) of the skin. As most of these viruses are uncharacterized, molecular characterization and epidemiology are needed to advance our understanding of their significance in carcinogenesis. This study determined the complete genomes of four betapapillomaviruses of species 2 from skin lesions designated HPV-107, -110 and -111 and FA75[KI88-03], an isolate of an unpublished HPV type, and analysed their prevalence and viral loads in biopsies from SCC, actinic keratosis (AK), basal cell carcinoma, seborrhoeic keratosis and the healthy skin of 263 immunocompetent patients by HPV type-specific real-time PCR assays. Seventeen patients (6.5 %) harboured at least one of the four HPV types in their lesion, whereas seven patients (2.7 %) harboured one or more of the HPV types in healthy skin. Overall, the four viruses were more common in AK than in healthy skin (odds ratio 5.0, 95 % confidence interval 1.4–17.5), but the prevalence and viral loads were low. This characterization of HPV-107, -110 and -111 and FA75[KI88-03] expands the heterogeneity of members of species 2 of the genus Betapapillomavirus. However, as these types were found in only a few samples and in low amounts, a possible role in carcinogenesis remains elusive.

Abstract
A human papillomavirus (HPV) was cloned from a patient with multiple squamous cell carcinomas (SCCs) and identified as HPV88, recently categorized into a new species within the genus Gamma. The HPV88 viral load in an SCC of the index patient exceeded 1 million copies/cell. By contrast, a survey of 447 skin lesions (79 actinic keratoses, 73 seborrhoeic keratoses, 169 basal cell carcinomas and 126 SCCs) and 362 healthy skin biopsies found detectable HPV88 DNA in only 7 specimens. All these had very low viral loads (<1 copy/10(3) cells) implying extreme biological variability in viral load.

Abstract
OBJECTIVES To assess the influences of the mutations within the long control region (LCR) and E2 open reading frame (ORF) of the human papillomavirus-2 (HPV-2) isolates from patients with extensive verrucae vulgaris with cutaneous horns in the activities of the viral early promoters. METHODS A PCR method was applied for screening HPV DNA in the lesion specimens and the complete HPV-2 genomes was analyzed. Recombinant CAT-reporter plasmids containing various HPV-2 LCRs and mammalian expression plasmids containing E2 ORF were constructed. The promoter activity was evaluated by transient transfection. RESULTS The whole HPV-2 genomes were obtained from both patients. Several mutations in LCR and mutations leading to alterations of amino acids in E2 protein were identified in isolate-1, while a few point mutations in LCR were seen in isolate-2. Under the control of LCRs, the viral early promoter activities of isolate-1 and isolate-2 were increased 3- and 2-fold, respectively. Alterations of amino acids in E2 protein of isolate-1 partially abolished its promoter repressive activity. Compared with that of prototype HPV-2, the promoter activity of isolate-1 in the presence of its E2-expressing plasmid was significantly increased. CONCLUSIONS The increased promoter activities might be linked, at least partially, to the clinical phenotypes of the uncommon huge verrucae vulgaris.

Abstract
Two novel human papillomaviruses (HPVs), HPV93 and HPV96, with genomes of 7450 and 7438 bp, respectively, are described. The L1 open reading frame of HPV93 showed highest identity to HPV24 (79%) and that of HPV96 had highest identity to HPV92 (71%). Real-time PCR for HPV92, 93 and 96 on stripped biopsies from tumours and healthy skin from 269 immunocompetent patients found HPV DNA in 2.6% of tumours and in 0.4% of healthy skin samples. Double infections were observed in two tumours. HPV92 was detected in four, HPV93 in two and HPV96 in three tumours. The range of viral loads spanned from one copy per 45 cells to one copy per 10,000 cells. The E7 proteins of HPV92, 93 and 96 were found to bind the retinoblastoma protein (pRb). These results suggest a possible role for these HPV types in skin carcinogenesis that deserves further study.

Abstract
The expression of the proteins encoded by human papillomaviruses (HPVs) is tightly linked to the differentiation program of the infected keratinocytes. The late promoter, expressing the structural proteins, becomes activated in the differentiated keratinocytes, while the early promoter is also active in the basal layers. We have shown previously that the viral transcriptional regulator E2 and the cellular coactivator p300 cooperate in activation of gene expression of HPV8, which infects the skin and is associated with epidermodysplasia verruciformis. Here we demonstrate that this activation is further stimulated after overexpression of the E6 oncoprotein of HPV8 (8E6). RNase protection experiments revealed that 8E6 efficiently cooperates with 8E2 and p300 in activation of the late promoter. In addition, the early promoter, which did not respond to 8E2 and/or p300, was stimulated more than fourfold by 8E6. Our data suggest that both promoters are activated via distinct mechanisms, since the activation of the early promoter was achieved by the N-terminal moiety of 8E6; in contrast, its C-terminal half was sufficient for late promoter activation. This was markedly reduced by the deletion of amino acids 132 to 136 of 8E6, which also abolished the binding to p300, indicating that a direct interaction between 8E6 and p300 is involved. Moreover, a 45-amino-acid segment within the C/H3 region of p300 is required for 8E6 to stimulate the coactivator function of p300. Our results demonstrate for the first time that an E6 oncoprotein of HPV directly contributes to the regulation of HPV gene expression.

Abstract
The human papillomaviruses (HPVs) exist as more than 100 distinct types. While variants of HPV are common, only few HPV subtypes have been reported. HPV type 38 has been proposed to be associated with nonmelanoma skin cancer (NMSC), with reported prevalences of up to 55%. A subtype of HPV38 was cloned, completely sequenced and found to have a 96% sequence similarity to prototype HPV38 in the L1 open reading frame. The presence of prototype HPV38 and HPV38b[FA125] was examined in paired biopsies of tape-stripped skin lesions and healthy skin from 269 immunocompetent patients by real-time PCR. Prototype HPV38 and HPV38b[FA125] were present in seven (3%) and five (2%) lesions, respectively, in viral loads ranging from one copy per 150 cells to one copy per 70,000 cells. In summary, we found that HPV38 is heterogeneous and is one of so far only few HPVs that contain subtypes. The heterogeneity needs to be considered in studies of the biology of this virus.

Abstract
Human papillomavirus type 8 (HPV8) poses a high risk for malignant conversion of skin lesions in patients with Epidermodysplasia verruciformis (Ev). Its oncogene promoter P(175) contains the conserved sequence motifs CCAAC, M29, and an A/T-rich region, which are common in many Ev-associated viruses. In human keratinocytes P(175) shows very weak activity. We used the M29 sequence as bait in a yeast-one-hybrid screen of a HaCaT cDNA library to identify interacting proteins regulating P(175). We report the identification of a cDNA encoding the interferon regulatory factor IRF5.2. In band shift assays the physical interaction of IRF5.2 and M29 was confirmed, and also its binding to the negative regulatory element (NRE) of HPV8 could be demonstrated. In transient reporter gene assays, overexpressed IRF5.2 acts as a transcriptional repressor of HPV8 and the Ev-associated HPV types 5, 14, and 25. These results indicate that the cellular transcription factor IRF5.2 is a general transcription repressor of Ev-associated HPV.

Abstract
Human papillomaviruses (HPVs) are DNA tumour viruses that induce hyperproliferative lesions in cutaneous and mucosal epithelia. The relationship between HPV and non-melanoma skin cancer (NMSC) is important clinically since NMSC is the most common form of malignancy among fair-skinned populations. It is well established that solar ultraviolet (UV) irradiation is the major risk factor for developing NMSC, but a pathogenic role for HPV in the development of NMSC has also been proposed. Recent molecular studies reveal a likely role for HPV infection in skin carcinogenesis as a co-factor in association with UV. This review summarizes the literature describing these data, highlights some of the important findings derived from these studies, and speculates on future perspectives.

Abstract
The beta and gamma genera of papillomaviruses consist of epidermodysplasia verruciformis-related human papillomaviruses (HPVs) and phylogenetically related cutaneous HPVs. Here, we have developed a consensus primer PCR assay and reverse line blot typing system coupled thereto (referred to as beta and gamma cutaneous HPV PCR [BGC-PCR]) for detection and typing of 24 beta and gamma HPVs (HPV types 4, 5, 8, 9, 12, 14, 15, 17, 19, 20, 21, 22, 23, 24, 25, 36, 37, 38, 47, 48, 49, 50, 60, and 65). Because the HPV-specific PCR products are only 72 bp in size, the system is suitable for formalin-fixed, paraffin-embedded specimens and other samples in which the DNA is of suboptimal quality. This system was able to detect and type as little as 100 ag to 1 fg HPV DNA per reaction (depending on the HPV type) in a background of 100 ng human DNA without any cross-reactivity between the tested types. Beta and gamma HPVs were detected in DNA extracted from plucked eyebrow hairs of 31 of 34 renal transplant recipients. In addition, formalin-fixed, paraffin-embedded specimens from nonmelanoma skin tumors of renal transplant recipients (n = 25) and immunocompetent individuals (n = 15) scored BGC-PCR positive in 21 and 6 cases, respectively, with HPV type 5 (HPV5) and HPV8 being the predominant types. The data indicate that this method can be a valuable, user-friendly tool for the detection and typing of cutaneous HPV in clinical specimens and may have implications for future monitoring of vaccines or alternative treatment modalities for diseases caused by these cutaneous HPVs.

Abstract
Recent studies suggest a role of cutaneous human papillomaviruses (HPV) in non-melanoma skin cancer (NMSC) development. In this study viral DNA loads of six frequent HPV types were determined by quantitative, type-specific real-time-PCR (Q-PCR) in actinic keratoses (AK, n=26), NMSC (n=31), perilesional tissue (n=22), and metastases of squamous cell carcinomas (SCC) (n=8) which were previously shown to be positive for HPV5, 8, 15, 20, 24, or 36. HPV-DNA loads in AK, (partially microdissected) NMSC, and perilesional skin ranged between one HPV-DNA copy per 0.02 and 14,200 cell equivalents (median: 1 HPV-DNA copy per 344 cell equivalents; n=48). In 32 of the 79 HPV-positive skin biopsies and in seven of the eight metastases viral loads were even below the detection limit of Q-PCR. Low viral loads in NMSC were confirmed by in situ-hybridization showing only a few HPV-DNA-positive nuclei per section. Viral loads in SCC, basal cell carcinomas, and perilesional tissue were similar. But, viral loads found in AK were significantly higher than in SCC (p=0.035). Our data suggest that persistence of HPV is not necessary for the maintenance of the malignant phenotype of individual NMSC cells. Although a passenger state cannot be excluded, the data are compatible with a carcinogenic role of HPV in early steps of tumor development.

Abstract
Recent insights into the cell biology of the epidermis and its appendages are transforming our understanding of the pathogenesis of basal cell carcinoma (BCC). The significant progress that has been made warrants a comprehensive review of the molecular and cellular pathology of BCC. The items addressed include environmental and genetic risk factors, the biology of the putative precursor cell(s), and the contribution of aberrations in processes such as apoptosis, cell proliferation, differentiation and signalling to carcinogenesis. Furthermore, established and novel treatment modalities are discussed with particular attention to future biological approaches.

Abstract
BACKGROUND DNA of epidermodysplasia verruciformis (EV)-associated human papillomaviruses (HPVs) has been widely detected in lesions of malignant skin tumours, benign tumours and other proliferative diseases of epithelial origin. OBJECTIVES To investigate the presence of EV-associated HPV DNA in nongenital seborrhoeic keratosis (SK) and to elucidate the prevalence of distinct HPV genotypes. METHODS We investigated HPV DNA in 55 nongenital SK biopsies, which were compared with 48 normal skin biopsies (healthy controls) using a nested polymerase chain reaction (PCR) using consensus primers CP65/CP70 and CP66/CP69. The positive PCR products were retracted and used to prepare recombination clones with T-vector. Distinct clones were analysed with endonucleases, and HPV genotypes were identified by direct sequencing. RESULTS EV-associated HPV DNA was detected in 42 of 55 (76%) nongenital SK biopsies vs. only 13 of 48 (27%) healthy controls (chi2 = 22.087; P < 0.005). The prevalence was higher in patients with more than five lesions than in those with only one lesion (P < 0.05). Ten distinct HPV genotypes were detected in the nongenital SK biopsies: HPV 20, 23, 5, renal transplant recipient (RTR) X7, HPV 17, 37, 17b, RTRX4, RTRX4b and strain SK3. HPV 20 was found in 26 of 42 (62%) positive specimens, followed by HPV 23 (11 of 42, 26%) and HPV 5 (six of 42, 14%). Existence of multiple HPV genotypes was observed in 12 of 42 (29%) positive specimens. In healthy controls, five genotypes of EV-associated HPV (HPV 20, 23, 5, 17 and RTRX4) were detected, with the same predominant genotype of HPV 20 (five of 13, 38%). Several distinct HPV genotypes were found to coexist in four of 13 (31%) positive specimens. CONCLUSIONS This study provides some evidence that EV-associated HPVs might play a part in the pathogenesis of nongenital SK.

Detection of various types of human papillomavirus DNA, mainly belonging to the cutaneous-group, more frequently in normal tissue than in squamous cell carcinomas of the lip. J Dermatol Sci 2005; 36:33-9. [PMID: 15488703 DOI: 10.1016/j.jdermsci.2004.07.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2004] [Revised: 07/05/2004] [Accepted: 07/15/2004] [Indexed: 11/15/2022]
Abstract
BACKGROUND Mucosal high-risk human papillomaviruses (HPVs), such as type 16, are detectable in oral cancers, especially of the oropharynx and tonsils, and there is evidence that they play a pathogenetic role in some cases. However, information is limited about their significance for cancers of the vermilion of the lip. OBJECTIVE To determine the detection rate, types and localization of HPVs in squamous cell carcinomas (SCCs) of the lip. METHODS Nested PCR for cutaneous HPVs, including epidermodysplasia verruciformis-related HPV (EV-HPV), and single PCR for mucosal HPVs, were conducted for a total of 27 SCCs and normal samples from 30 individuals. Tyramide-based in situ hybridization (ISH) was also applied. RESULTS Various types of HPVs were detected, particularly from normal individuals. Among the kinds of the HPV types detected in this study, half were found by PCR using a primer pair, which we newly designed. The prevalence of HPV was 5 out of 27 SCCs (ca. 18%) and 10 out of 30 normal individuals (ca. 33%). They were the entire cutaneous-group except for two, from one SCC and one normal individual. CONCLUSION On the surface of the normal lip various types of mainly cutaneous-group HPVs may be present, but there does not appear to be any obvious association with SCCs developing in this site.

Abstract
The cutaneous human papillomavirus (HPV) 8 is clearly involved in skin cancer development in epidermodysplasia verruciformis patients and its early genes E2, E6, and E7 have been implicated in cell transformation in vitro. To examine the functions of these genes in vivo we integrated the complete early region of HPV8 into the genome of DBA/Bl6 mice. To target their expression to the basal layer of the squamous epithelia the transgenes were put under the control of the keratin-14 promoter. Transgenic mice were back-crossed for up to six generations into both FVB/N and Bl6 mouse strains. Whereas none of the HPV8 transgene-negative littermates developed lesions in the skin or any other organ, 91% of HPV8-transgenic mice developed single or multifocal benign tumors, characterized by papillomatosis, acanthosis, hyperkeratosis, and varying degrees of epidermal dysplasia. Squamous cell carcinomas developed in 6% of the transgenic FVB/N mice. Real-time reverse transcription-PCR showed highest expression levels for HPV8-E2, followed by E7 and E6. There was no consistent difference in relative viral RNA levels between healthy or dysplastic skin and malignant skin tumors. Whereas UV-induced mutations in the tumor suppressor gene p53 are frequently detected in human skin carcinomas, mutations in p53 were not observed either in the benign or malignant mouse tumors. Nonmelanoma skin cancer developed in HPV8-transgenic mice without any treatment with physical or chemical carcinogens. This is the first experimental proof of the carcinogenic potential of an epidermodysplasia verruciformis-associated HPV-type in vivo.

Abstract
O conhecimento dos principais mecanismos de defesa imune contra os diversos agentes infecciosos permite a compreensão da patogênese das doenças infectoparasitárias e das várias estratégias do hospedeiro e do parasita. O sistema imunológico atua numa rede de cooperação, envolvendo a participação de muitos componentes estruturais, moleculares e celulares. Nesse cenário encontra-se o delicado equilíbrio entre a saúde e a doença, em que tanto a deficiência quanto o exagero resultam em dano tecidual. Este artigo explora esses aspectos e algumas abordagens terapêuticas que surgem desse entendimento.

Abstract
Genomes of human papillomaviruses (HPV) are common in biopsies from non-melanoma skin cancers but are also found on healthy skin and it is possible that HPV positivity in tumor biopsies by PCR may merely reflect contamination of the lesion surface. To investigate this issue, 229 immunocompetent patients were tested for HPV DNA in swab samples collected on top of skin tumors and in biopsies of the same tumors, obtained after stripping with tape to remove superficial layers. HPV DNA was detected on top of 69% (159 of 229) of the lesions, and in 12% (28 of 229) of the stripped biopsies (p<0.001). The difference was seen for all four types of tumors studied. Seborrheic keratosis had 79% (34 of 43) HPV positivity on top of lesions versus 19% (eight of 43) in biopsies; actinic keratosis had 83% (38 of 46) HPV positivity on top versus 11% (five of 46) in biopsies; basal cell carcinoma had 63% (69 of 109) on top versus 8% (nine of 109) in biopsies and squamous cell carcinoma had 58% (18 of 31) on top versus 19% (six of 31) in biopsies. HPV DNA is common in superficial layers of lesions, but is not necessarily present throughout tumors.

Abstract
Ultraviolet radiation (UVR) is associated with an increased risk of squamous cell carcinoma (SCC), which is in part due to immunomodulation. In addition, human papilloma virus (HPV), especially the epidermodysplasia verruciformis (EV)-associated types, may be involved. In view of the capacity of UVR to impair host resistance to infections, we investigated the relationship between solar exposure and the prevalence of cutaneous HPV. In a case-control study on skin cancer (320 controls and 156 patients) a lifetime-retrospective questionnaire on sun exposure was administered. The presence of DNA of HPV types 5, 8, 15, 20, 24, and 38 in plucked eyebrow hair and type-specific seroreactivity were assessed and analyzed in relation to estimated exposure. Sunburn episodes in the past, especially at age 13-20 y, appeared to be associated with an enhanced risk of EV-HPV DNA positivity. In contrast, a higher lifetime sun exposure was associated with a lower risk of HPV infection. These results indicate that UVR at erythematogenic doses increases the risk of EV-HPV infection, possibly due to impaired host resistance to HPV and/or a direct effect of UVR on viral replication. The favorable association between lifetime sun exposure and HPV prevalence, however, underscores the enigmatic role of HPV in skin carcinogenesis.

Abstract
BACKGROUND Human papillomavirus (HPV) infection has been suggested to be involved in the development of nonmelanoma skin cancer, the most common malignancy after solid-organ transplantation. OBJECTIVE The objective of this study was to analyze the prevalence of different HPV types in squamous cell carcinomas (SCC) and basal cell carcinomas (BCC) of transplant recipients and nonimmunosuppressed patients. METHODS To include the complete spectrum of HPV types in skin lesions, a comprehensive polymerase chain reaction assay with five different primer combinations was used. RESULTS For SCC, HPV DNA was detected more frequently in tumors of transplant recipients (12/16, 75%) than of nonimmunosuppressed patients (7/19, 37%). In contrast, the HPV detection rate was similar in BCC specimens (4/8 or 50% in transplanted patients; 27/56 or 48% in nonimmunosupressed patients). Overall, 22 different HPV types were identified. HPV types 5 and 8 were detected predominately in SCC from transplant recipients. The amount of viral DNA was slightly higher in SCC of transplanted than in nonimmunosuppressed patients, but much lower than in both cutaneous and genital warts. CONCLUSIONS Cutaneous infections with HPV5 and HPV8 may represent an increased risk for SCC development in transplant recipients. The mechanisms by which these viruses may contribute to skin cancer development still remain unclear.

Abstract
Using PCR, the overall prevalence of human papillomavirus (HPV) DNA in penile carcinoma is about 40-45%, which is similar to the detection rate of HPV-DNA in vulvar carcinoma (50%). In analogy to vulvar cancer two different pathways of penile carcinogenesis seem to exist. In contrast to basaloid and warty penile cancers which are regularly HPV-associated (about 80-100%), only a part of keratinizing and verrucous penile carcinomas appear to be related with HPV (33-35%). Penile intraepithelial neoplasias comprising Bowen's disease, erythroplasia of Queyrat and bowenoid papulosis are precursor lesions of basaloid and warty carcinomas of the penis. Precursors of keratinizing carcinomas and verrucous carcinomas are not established. Whether lichen sclerosus and squamous-cell hyperplasia precede penile keratinizing carcinoma is a matter of discussion. Giant condylomata acuminata may precede the development of verrucous carcinomas in some cases. Since high risk HPVs are more frequently found in verrucous carcinomas than in giant condylomas, HPV typing may be a helpful diagnostic step to differentiate giant condyloma from verrucous carcinoma.

Abstract
A role for cutaneous human papillomaviruses (HPV) has been proposed in the development of skin cancer. Well-designed epidemiologic studies to demonstrate an association between HPV infection and skin cancer are extremely rare. To identify HPV infection as a potential risk factor, we investigated the association between the presence of HPV DNA in eyebrow hairs and a history of cutaneous squamous cell carcinoma. A case-control study was designed consisting of 155 immunocompetent individuals with a history of squamous cell carcinoma and 371 controls without skin cancer. DNA extracted from plucked eyebrow hairs collected from the study population was analyzed with a cutaneous HPV subgroup polymerase chain reaction and newly designed HPV type specific polymerase chain reactions for HPV 2, 5, 8, 15, 16, 20, 24, and 38. HPV DNA was detected in 63.1% of the total study population. The presence of HPV DNA was associated with age (p=0.0002) and male sex (p=0.02), but not with sun exposure, skin type, and smoking. After adjustment for age and sex, the presence of HPV DNA in eyebrow hairs was associated with a history of squamous cell carcinoma (odds ratio 1.7, 95% confidence interval 1.1; 2.7). HPV type specific analysis revealed that no HPV type stood out. The high-risk mucosal type HPV 16 and the skin wart type HPV 2 were rarely found in this study (<0.2%). The positive association found between the presence of HPV DNA in eyebrow hairs and a history of squamous cell carcinoma warrants further research into the role that HPV infection plays in the development of cutaneous squamous cell carcinoma.
