Abstract
Squamous cell carcinoma of the head and neck (HNSCC) is a malignant cancer disease in humans and animals. There is ample evidence that the high plasticity of cancer cells, i.e., their ability to switch from an epithelial to a mesenchymal, endothelial, and stem cell-like phenotype, chiefly contributes to progression, metastasis, and multidrug resistance of human HNSCCs. In feline HNSCC, the field of cancer cell plasticity is still unexplored. In this study, fourteen feline HNSCCs with a known feline papillomavirus (FPV) infection status were subjected to histopathological grading and subsequent screening for expression of epithelial, mesenchymal, and stem cell markers by immunohistochemistry (IHC) and immunofluorescence staining (IF). Irrespective of the FPV infection status, all tumors except one corresponded to high-grade, invasive lesions and concurrently expressed epithelial (keratins, E-cadherin, β-catenin) and mesenchymal (vimentin, N-cadherin, CD146) proteins. This finding is indicative for partial epithelial-mesenchymal transition (pEMT) events in the lesions, as similarly described for human HNSCCs. IF double staining revealed the presence of CD44/CD271 double-positive cells notably within the tumors' invasive fronts that likely correspond to cancer stem cells. Taken together, the obtained findings suggest that feline HNSCCs closely resemble their human counterparts with respect to tumor cell plasticity.

Abstract
Squamous cell carcinoma of the head and neck (HNSCC) is a common malignant tumor in humans and animals. In humans, papillomavirus (PV)-induced HNSCCs have a better prognosis than papillomavirus-unrelated HNSCCs. The ability of tumor cells to switch from epithelial to mesenchymal, endothelial, or therapy-resistant stem-cell-like phenotypes promotes disease progression and metastasis. In equine HNSCC, PV-association and tumor cell phenotype switching are poorly understood. We screened 49 equine HNSCCs for equine PV (EcPV) type 2, 3 and 5 infection. Subsequently, PV-positive versus -negative lesions were analyzed for expression of selected epithelial (keratins, β-catenin), mesenchymal (vimentin), endothelial (COX-2), and stem-cell markers (CD271, CD44) by immunohistochemistry (IHC) and immunofluorescence (IF; keratins/vimentin, CD44/CD271 double-staining) to address tumor cell plasticity in relation to PV infection. Only EcPV2 PCR scored positive for 11/49 equine HNSCCs. IHC and IF from 11 EcPV2-positive and 11 EcPV2-negative tumors revealed epithelial-to-mesenchymal transition events, with vimentin-positive cells ranging between <10 and >50%. CD44- and CD271-staining disclosed the intralesional presence of infiltrative tumor cell fronts and double-positive tumor cell subsets independently of the PV infection status. Our findings are indicative of (partial) epithelial–mesenchymal transition events giving rise to hybrid epithelial/mesenchymal and stem-cell-like tumor cell phenotypes in equine HNSCCs and suggest CD44 and CD271 as potential malignancy markers that merit to be further explored in the horse.

Abstract
Increasing evidence suggests that microorganisms might represent at least highly interesting cofactors in colorectal cancer (CRC) oncogenesis and progression. Still, associated mechanisms, specifically in colonocytes and their microenvironmental interactions, are still poorly understood. Although, currently, at least seven viruses are being recognized as human carcinogens, only three of these – Epstein–Barr virus (EBV), human papillomavirus (HPV) and John Cunningham virus (JCV) – have been described, with varying levels of evidence, in CRC. In addition, cytomegalovirus (CMV) has been associated with CRC in some publications, albeit not being a fully acknowledged oncovirus. Moreover, recent microbiome studies set increasing grounds for new hypotheses on bacteriophages as interesting additional modulators in CRC carcinogenesis and progression. The present Review summarizes how particular groups of viruses, including bacteriophages, affect cells and the cellular and microbial microenvironment, thereby putatively contributing to foster CRC. This could be achieved, for example, by promoting several processes – such as DNA damage, chromosomal instability, or molecular aspects of cell proliferation, CRC progression and metastasis – not necessarily by direct infection of epithelial cells only, but also by interaction with the microenvironment of infected cells. In this context, there are striking common features of EBV, CMV, HPV and JCV that are able to promote oncogenesis, in terms of establishing latent infections and affecting p53‐/pRb‐driven, epithelial–mesenchymal transition (EMT)‐/EGFR‐associated and especially Wnt/β‐catenin‐driven pathways. We speculate that, at least in part, such viral impacts on particular pathways might be reflected in lasting (e.g. mutational or further genomic) fingerprints of viruses in cells. Also, the complex interplay between several species within the intestinal microbiome, involving a direct or indirect impact on colorectal and microenvironmental cells but also between, for example, phages and bacterial and viral pathogens, and further novel species certainly might, in part, explain ongoing difficulties to establish unequivocal monocausal links between specific viral infections and CRC.

Characteristics of head and neck squamous cell carcinoma cell Lines reflect human tumor biology independent of primary etiologies and HPV status. Transl Oncol 2020; 13:100808.

Abstract
Explanations for the differences in clinical outcomes in head and neck squamous cell carcinomas (HNSCCs) when compared by similar tumor location, stage, nodal status, human papillomavirus (HPV) status, and patient history remain elusive. Cell lines are an excellent tool of study for understanding the in vitro properties of cancers. However, HNSCC cell lines from progression-free and/or HPV-positive tumors are very rare. Here we studied HPV-positive and HPV-negative University of Michigan squamous cell carcinoma cell lines (2 HPV−, 2 HPV16+, 1 HPV18+) coming from donors with nonoropharyngeal sites and variant clinical outcomes. Cell morphology and proliferation were assessed, and immunofluorescence and Western blotting evaluated tumor biomarkers (TP53, RB1, p16, HPV E6 and E7, EGFR, Cyclin D1, Ki-67, and beta-catenin). Slow in vitro proliferation, long lag phase before exponential proliferation, lower maximal cell density, and higher wild-type TP53 expression were common to cell lines from patients who experienced long-term disease-free survival. In contrast, shorter lag phases, rapid proliferation, and high maximal cell density were observed in cell lines from patients who experienced aggressive tumor progression leading to death. Membrane-bound beta-catenin was present in all cell lines, but nuclear beta-catenin was associated with the more lethal cancers. In summary, the HNSCC cell lines present key characteristics, independent of primary etiologies and HPV infection, that mirror the behavior of the tumors from which they were derived.

Abstract
The knowledge about the molecular alterations which are found in head and neck squamous cell carcinomas (HNSCC) has much increased in recent years. However, we are still awaiting the translation of this knowledge to new diagnostic and therapeutic options. Among the many molecular changes that are detected in head and neck cancer, the abnormalities in several signaling pathways, which regulate cell proliferation, cell death and stemness, seem to be especially promising with regard to the development of targeted therapies. Canonical Wnt signaling is a pathway engaged in the formation of head and neck tissues, however it is not active in adult somatic mucosal cells. The aim of this review paper is to bring together significant data related to the current knowledge on the mechanisms and functional significance of the dysregulation of the Wnt/β-catenin pathway in head and neck tumors. Research evidence related to the role of Wnt signaling activation in the stimulation of cell proliferation, migration and inhibition of apoptosis in HNSCC is presented. Moreover, its role in promoting stemness traits in head and neck cancer stem-like cells is described. Evidence corroborating the hypothesis that the Wnt signaling pathway is a very promising target of novel therapeutic interventions in HNSCC is also discussed.

Abstract
Human papillomavirus type 16 (HPV16) is a major risk for development of oropharyngeal squamous-cell-carcinoma (OPSCC). Although HPV+ OPSCC metastasize faster than HPV- tumors, they have a better prognosis. The molecular and cellular alterations underlying this pathobiology of HPV+ OPSCC remain elusive. In this study, we examined whether expression of HPV16-E6E7 targets the number of migratory and stationary cancer stem cells (CSC). Furthermore, we wanted to elucidate if aberrantly expressed miRNAs in migratory CSC may be responsible for progression of OPSCCs and whether they may serve as potential novel biomarkers for increased potential of metastasis. Our studies revealed that HPV16-E6E7 expression leads to an increase in the number of stationary (CD44high /EpCAMhigh ) stem cells in primary keratinocyte cultures. Most importantly, expression of E6E7 in the cell line H357 increased the migratory (CD44high /EpCAMlow ) CSC pool. This increase in migratory CSCs could also be confirmed in HPV+ OPSCC. Differentially expressed miRNAs from HPV16-E6E7 positive CD44high /EpCAMlow CSCs were validated by RT-qPCR and in situ hybridization on HPV16+ OPSCCs. These experiments led to the identification of miR-3194-5p, which is upregulated in primary HPV16+ OPSCC and matched metastasis. MiR-1281 was also found to be highly expressed in HPV+ and HPV- metastasis. As inhibition of this miRNA led to a markedly reduction of CD44high /EpCAMlow cells, it may prove to be a promising drug target. Taken together, our findings highlight the capability of HPV16 to modify the phenotype of infected stem cells and that miR-1281 and miR3194-5p may represent promising targets to block metastatic spread of OPSCC.

Abstract
Oncoviruses are implicated in around 20% of all human cancers including both solid and non-solid malignancies. Epstein–Barr virus (EBV) and human papillomaviruses (HPVs) are the most common oncoviruses worldwide. Currently, it is well established that onco-proteins of EBV (LMP1, LMP2A, and EBNA1) and high-risk HPVs (E5 and E6/E7) play an important role in the initiation and/or progression of several human carcinomas, including cervical, oral, and breast. More significantly, it has been recently pointed out that viral onco-proteins of EBV and high-risk HPVs can be co-present and consequently cooperate to initiate and/or amplify epithelial–mesenchymal transition (EMT), which is the hallmark of cancer progression and metastasis. This could occur by β-catenin, JAK/STAT/SRC, PI3k/Akt/mTOR, and/or RAS/MEK/ERK signaling pathways, which onco-proteins of EBV and HPVs share. This review presents the most recent advances related to EBV and high-risk HPVs onco-proteins interactions and their roles in the progression of human carcinomas especially oral and breast via the initiation of EMT.

Abstract
BACKGROUND The purpose of this work was to investigate the prognostic significance of E-cadherin and β-catenin expression in surgically treated human papillomavirus (HPV)-negative patients with oropharyngeal squamous cell carcinoma (SCC). METHODS Consecutive patients with oropharyngeal SCC who underwent surgical treatment between 1990 and 2009 were retrospectively collected. Immunohistochemical analysis of E-cadherin and β-catenin expression was performed on tissue microarrays. RESULTS E-cadherin and β-catenin expression was evaluable in 232 cases. Low membranous E-cadherin, low membranous β-catenin expression, and nuclear β-catenin expression were associated with a poorer disease-specific and overall survival, although the differences were only significant for β-catenin membranous expression (P = .024 and P = .016, respectively). In multivariate analysis, nodal metastasis and low membranous β-catenin expression were significant independent predictors of reduced disease-specific and overall survival. CONCLUSION Low membranous β-catenin expression is a significant independent predictor of both reduced disease-specific and overall survival in patients with HPV-negative oropharyngeal SCC.

Abstract
BACKGROUND p16 overexpression is a highly sensitive yet moderately specific biomarker for predicting human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC). Nuclear β-catenin translocation has been linked to HPV-positive OPSCC. However, whether the strategy of combining β-catenin with p16 can better predict HPV-associated OPSCC remains unknown. METHODS We evaluated the expression of p16 and β-catenin (nuclear and membrane) by immunohistochemistry staining in 101 OPSCC tissues and HPV status by HPV DNA in situ hybridization. Logistic regression models were used to evaluate single or multiple biomarkers for HPV prediction. The prediction power, sensitivity, and specificity were determined by receiver operating characteristic (ROC) analyses. RESULTS Our data showed that upon univariate analysis, p16 and nuclear β-catenin were positively correlated with HPV status, while membrane β-catenin was inversely correlated with HPV status (P < 0.01). p16 showed the highest HPV predictive power, with area under the curve (AUC) of 0.9074 compared to 0.6762 for nuclear β-catenin and 0.7635 for membrane β-catenin, respectively, indicating differential accuracies for HPV prediction. Multivariable analysis showed that p16 was significantly correlated with HPV, while nuclear and membrane β-catenin showed marginal significance. The three-biomarker model was similarly sensitive (98.9% vs. 100%) but more specific (88.9% vs. 81%) than p16 alone, which also showed a good predictive value for overall (P = 0.0002) survival and disease-free (P = 0.0158) survival. CONCLUSION Our study suggests a novel model of combining p16 and subcellular β-catenin for prediction of HPV-associatred OPSCC, and this finding deserves further validation.

Human papillomavirus 16 oncoprotein regulates the translocation of β-catenin via the activation of epidermal growth factor receptor. Cancer 2014; 121:214-25. [PMID: 25209444 DOI: 10.1002/cncr.29039] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2014] [Revised: 08/15/2014] [Accepted: 08/19/2014] [Indexed: 01/01/2023]
Abstract
BACKGROUND To understand the mechanism of frequent and early lymph node metastasis in high-risk human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC), this study investigated whether β-catenin is regulated by the HPV oncoprotein and contributes to OPSCC metastasis. METHODS Expression levels of p16, β-catenin, and epidermal growth factor receptor (EGFR) were examined in OPSCC samples (n = 208) by immunohistochemistry. The expression and subcellular localization of β-catenin and EGFR activation were also studied in HPV-positive and HPV-negative head and neck squamous cell carcinoma cell lines with western blot analysis. HPV16 E6 small interfering RNA was used to elucidate the effect of the HPV oncoprotein on β-catenin translocation. The involvement of EGFR in β-catenin translocation was confirmed by treatment with erlotinib. Moreover, the invasive capacity was evaluated after HPV16 E6/E7 repression. RESULTS The results showed that the membrane weighted index of β-catenin was inversely correlated with p16 positivity (P < .001) and lymph node metastasis (P = .026), whereas nuclear staining of β-catenin was associated with p16-positive OPSCC (P < .001). A low level of membrane β-catenin expression was significantly associated with disease-free and overall survival (P < .0001 in both cases). Furthermore, the membrane weighted index of EGFR was inversely correlated with p16 positivity (P < .001) and positively correlated with membrane β-catenin (P < .001). The in vitro study showed that HPV16 E6 repression led to reductions of phospho-EGFR and nuclear β-catenin, which were also observed after erlotinib treatment, and inhibition of invasion. CONCLUSIONS The findings suggest that HPV16 E6 mediates the translocation of β-catenin to the nucleus, which may be regulated by activated EGFR.

Abstract
Malignant peripheral nerve sheath tumors (MPNST) are incurable tumors of the Schwann cell lineage that progress unpredictably from benign plexiform neurofibromas. In this issue of Cancer Discovery, Watson and colleagues use an insertional mutagenesis screen combined with network analysis to identify the canonical WNT signaling pathway as an important potential biomarker of tumor progression and target for combination therapy in MPNSTs.

Abstract
The aim of this study was to determine the proportion of human papilloma virus (HPV)-positive cases in tonsillar carcinomas and investigate its development over the last decade. Further aim was to show the oncologic results in accord to HPV status and various treatment modalities. A retrospective study was conducted between 2000 and 2012 and included 275 patients treated for tonsillar carcinoma. P16 immunohistochemistry was used as a surrogate marker for HPV-associated carcinogenesis. A total of 101 (36.7%) patients proved to be p16 positive and 174 p16 negative. 80.2% of the p16-positive cases presented with T1-2 tumor. Of the early-stage patients, 79% of the p16-positive and 52.3% of the p16-negative presented with lymph node metastases. The percentage of p16-positive patients increased from 23.2% in the period 2005–2007 to 58.6% in the period 2010–2012 in the whole population and from 30.9% to 76.9% in T1-2 carcinomas. Early T-category p16-positive carcinomas had significantly better disease-specific survival (92.4% vs. 75.5%, P = 0.007) and overall survival (OS, 79.6% vs. 54.3%, P < 0.001) compared to p16-negative tumors. This study showed an increase in the percentage of p16-positive patients in tonsillar carcinoma from 23.2% in the years between 2005 and 2007 to 58.6% between 2010 and 2012. The majority (80.2%) of p16-positive patients presented with early T-category tumor but most of these (79.0%) had also lymph node metastases. Nevertheless, p16-positive patients had excellent oncologic results after surgery and adjuvant radiotherapy and could be considered for de-escalation of treatment.

Abstract
There is increasing evidence worldwide that human papillomavirus is a major risk factor for head and neck cancer. Only few studies on this association have been performed in Germany to date. For the purposes of the present study, tumor specimens from 223 patients with squamous cell cancer of the oral cavity, oropharynx, hypopharynx and larynx were analyzed for HPV DNA and p16INK4a expression. The prevalence of HPV genotype 16 (HPV16) DNA in the study population was 17.5%. Further high-risk HPV types were not detected. All HPV16-positive tumors showed intense p16INK4a expression. HPV16 prevalence was highest in tonsillar carcinoma (37.5%) and lowest in laryngeal cancer (2.8%). We observed a significantly higher incidence of cervical lymph node metastases in patients with HPV16-positive tonsillar carcinoma in comparison to HPV-negative tumors (p < 0.016). Tobacco and/or alcohol consumption was significantly lower in patients with HPV-positive tumors (p < 0.0001).

Clinical significance of altered expression of β-catenin and E-cadherin in oral dysplasia and cancer: potential link with ALCAM expression. PLoS One 2013; 8:e67361. [PMID: 23840677 PMCID: PMC3696121 DOI: 10.1371/journal.pone.0067361] [Citation(s) in RCA: 55] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2012] [Accepted: 05/16/2013] [Indexed: 01/23/2023] Open
Abstract
Background Perturbations in cell adhesion molecules are linked to alterations in cadherin-catenin complexes and likely play major roles in invasion and metastasis; their impact on early precancerous stages remains yet unknown. We showed ALCAM overexpression in early oral lesions and its cytoplasmic accumulation in oral squamous cell carcinoma (OSCC) to be a predictor of disease progression and poor prognosis. This study tested the hypothesis that alterations in E-cadherin and β -catenin expressions are early events in oral tumorigenesis, associated with disease prognosis, and correlate with perturbations in ALCAM expression. Methods Expressions of E-cadherin and β-catenin were analyzed in the same cohort of 105 OSCCs, 76 oral lesions and 30 normal oral tissues by immunohistochemistry and correlated with clinicopathological parameters and prognosis. The effect of siRNA mediated ALCAM knockdown on E-cadherin and β -catenin was determined using western blot, confocal microscopy and RT-PCR analysis in oral cancer cells. Results Significant loss of membranous E-cadherin and β-catenin expression was observed from normal, hyperplasia, dysplasia to OSCCs (ptrend <0.001); and correlated with cytoplasmic ALCAM accumulation in OSCCs (p = 0.006). Multivariate analysis revealed β-catenin membrane loss and ALCAM/β-cateninnuclear/cytoplasmic accumulation to be significant predictors for late clinical stage (p<0.001, OR = 8.7; p = 0.006, OR = 9.9, respectively) and nodal metastasis (p = 0.003, OR = 3.8; p = 0.025, OR = 3.4 respectively). Cox’s regression showed E-cadherin membrane loss/ALCAM cytoplasmic expression [p<0.001; HR = 4.8] to be independent adverse prognosticators in OSCCs. siRNA mediated silencing of ALCAM resulted in concurrent increase in E-cadherin and β-catenin both at the transcript and protein levels. Conclusions Losses of E-cadherin and β-catenin expressions are early events in oral tumorigenesis; their associations with aggressive tumor behavior and disease recurrence underscore their potential as prognostic markers. Correlation of loss of E-cadherin and β-catenin with cytoplasmic ALCAM accumulation both in vitro and in in vivo suggests that these dynamic changes in cell adhesion system may play pivotal role in oral cancer.

Abstract
Nasopharyngeal carcinoma has a high incidence in southern China. The Wnt/β-catenin signaling pathway plays a major role in cancer development and progression. Our current study aims to determine the clinical significance of the Wnt/β-catenin pathway components such as β-catenin, cyclooxygenase 2, cyclin D1, c-Myc, and E-cadherin in 148 nasopharyngeal carcinomas by immunohistochemistry. We found that nasopharyngeal carcinoma stage T3+T4 had significantly higher expression of β-catenin, cyclooxygenase 2, cyclin D1, and c-Myc and lower expression of E-cadherin than nasopharyngeal carcinoma stage T1+T2 (P < .001, P < .05, respectively).There was significantly higher expression of β-catenin (P = .001) and cyclooxygenase 2 (P = .003) and lower expression of E-cadherin (P = .001) in nasopharyngeal carcinoma with lymph node metastasis than in nasopharyngeal carcinoma without lymph node metastasis. The expression of β-catenin in nasopharyngeal carcinoma was positively correlated with cyclooxygenase 2 (r = 0.458, P < .0001), cyclin D1 (r = 0.700, P < .0001), and c-Myc expression (r = 0.144, P = .006) but negatively correlated with E-cadherin expression (r = -0.601, P < .0001), respectively. The univariate analysis confirmed that overexpression of β-catenin and cyclooxygenase 2 and decreased expression of E-cadherin were significantly correlated with disease-free survival (P < .01, P < .05, respectively). Overexpression of β-catenin and cyclooxygenase 2 and reduced expression of E-cadherin significantly correlated with a poor prognosis (P = .005, P = .044, P = .019, respectively) by Kaplan-Meier survival curves and the log-rank test. Multivariate analysis indicated that high expression of β-catenin and decreased expression of E-cadherin were independent prognostic factors (P = .002, P = .011, respectively) regardless of TNM stage and lymph node status. In conclusion, the aberrant high expression of β-catenin and decreased expression of E-cadherin is associated with poor prognosis in nasopharyngeal carcinoma.

Abstract
Head and Neck Squamous Cell Carcinomas (HNSCC) are the 6(th) most common cancers worldwide. While incidence rates for cancer of the hypopharynx and larynx are decreasing, a significant increase in cancer of the oropharynx (OSCC) is observed. Classical risk factors for HNSCC are smoking and alcohol. It has been shown for 25 to 60% of OSCC to be associated with an infection by oncogenic human papilloma viruses (HPV). The development of "common" cancer of the head and neck is substantially enhanced by an accumulation of genetic changes, which lead to an inactivation of tumor suppressor genes or activation of proto-oncogenes. A more or less uniform sequence of different DNA-damages leads to genetic instability. In this context, an early and frequent event is deletion on the short arm of chromosome 9, which results in inactivation of the p16-gene. In contrast, for HPV-induced carcinogenesis, expression of the viral proteins E6 and E7 is most important, since they lead to inactivation of the cellular tumor-suppressor-proteins p53 and Rb. The natural route of transoral infection is a matter of debate; peroral HPV-infections might be frequent and disappear uneventfully in most cases. Smoking seems to increase the probability for developing an HPV-associated OSCC. The association of HNSCC with HPV can be proven with established methods in clinical diagnostics. In addition to classical prognostic factors, diagnosis of HPV-association may become important for selection of future therapies. Prognostic relevance of HPV probably surmounts many known risk-factors, for example regional metastasis. Until now, no other molecular markers are established in clinical routine. Future therapy concepts may vary for the two subgroups of patients, particularly patients with HPV-associated OSCC may take advantage of less aggressive treatments. Finally, an outlook will be given on possible targeted therapies.

Abstract
Tonsillar squamous cell carcinoma (TSCC) is frequently associated with human papillomavirus (HPV) and chromosome instability. Data from cellular model systems are, however, controversial concerning a relation between HPV and chromosome instability development. Here we studied this association in 77 primary TSCC with known clinical outcome and cell cycle protein expression profiles. Thirty-two tumors (42%) showed HPV16-integration. All 77 cases were analyzed by fluorescence in situ hybridization using chromosome 1- and 7-specific centromere DNA probes to detect chromosome instability, indicated by the presence of chromosome imbalances and/or polyploidization for these chromosomes. In addition, eight HPV-positive dysplasias, seven of which were adjacent to a carcinoma, were analyzed. Disomy for chromosome 1 and 7 was present in 29 out of 77 TSCC (38%), of which 19 were HPV16-positive (p = 0.002). Aneusomy was observed in the remaining 48 TSCC, of which 13 were HPV-positive. Aneusomies correlated significantly with tobacco- and alcohol consumption (p = 0.001 and p = 0.016, respectively) and a higher T-stage (p = 0.018). Both HPV-positivity and chromosome disomy were significantly associated with a favorable disease-free survival (p = 0.001 and p = 0.025, respectively). Particularly in the HPV16-positive group chromosome instability is a very strong indicator for an unfavorable prognosis (p = 0.032). In the dysplasias an identical HPV and chromosome copy number status was identified as in the adjacent tumors. We conclude that HPV-positive TSCC and their precursor lesions are more often genetically stable than HPV-negative lesions and that these tumors are associated with a favorable prognosis. Chromosome instability is an indicator for unfavorable prognosis, particularly in the HPV-positive patient group.

Abstract
BACKGROUND The influence of human papillomavirus (HPV) status on survival for patients with very advanced inoperable oropharyngeal SCC treated with radiochemotherapy (RCT) was studied. METHODS Patients received either 69.2 Gy with concomitant boost (ccb) or 70 Gy conventionally fractionated (cf), weekly paclitaxel 40 mg/m(2), and carboplatin area under the concentration-time curve (AUC) 1. Tumor was analyzed for the presence of high-risk HPV-DNA using polymerase chain reaction (PCR) and direct DNA sequencing. p16-expression, survivin, and epidermal growth factor receptor (EGFR) expression were evaluated by immunohistochemistry and influence on survival was calculated. RESULTS Of 52 patients, 25.0% were HPV positive and 75.0% HPV negative. The 2-year progression-free survival (PFS) was 70.1% for p16-positive patients and 37.1% for p16-negative patients (p = .005). The 3-year overall survival (OS) rate was 43.9% for all patients and did not significantly differ between the groups. Neither survivin nor EGFR expression influenced PFS or OS significantly. CONCLUSIONS HPV status influences PFS in patients with advanced, nonresectable tumor stages but not OS. Additional risk factors seem to have a stronger influence on survival than HPV status.

Abstract
Identification of molecular pathways that are essential for cancer cell survival is vital for understanding the underlying biology, as well as to design effective cancer therapeutics. β-catenin, a multifunctional oncogenic protein, participates in cell development. Its multifaceted functions primarily lie to the subcellular distribution. The present study demonstrated that β-catenin accumulated in the nucleus to a greater extent in high-grade gliomas compared with low-grade gliomas. In addition, nuclear localization correlated with a worse prognosis for patients, as determined by immunohistochemical analysis of 74 glioma samples. Nuclear expression of β-catenin was down-regulated in LN229 and U87 glioma cells by a small molecule inhibitor of β-catenin/TCF4 signaling, demonstrating strongly inhibited β-catenin/TCF4 transcriptional activity and STAT3 luciferase activity, as well as decreased mRNA and protein levels of nuclear β-catenin, TCF4, EGFR, AKT1, AKT2 and STAT3. Furthermore, repressed nuclear translocation of β-catenin resulted in inhibition of proliferation and invasiveness, and also induced apoptosis of glioma cells. Similar results were also observed in vivo; intratumoral injection of such small molecule inhibitor downregulated expression of nuclear β-catenin, TCF4, and components of the EGFR pathway, and also delayed tumor growth in nude mice harboring subcutaneous U87 xenografts. Results from the present study provided evidence that nuclear accumulation of β-catenin participated in malignant progression of gliomas and implicated poor prognosis, highlighting it as a potential therapeutic target for gliomas.

Abstract
Translational research refers to the interfaces between preclinical research and targeted short- and medium-term developments through to clinical standards. There are two distinct groups of oropharyngeal malignancies: those caused by tobacco and alcohol abuse and those caused by HPV infection. Although the prognosis of patients in the latter group is significantly better, this is not taken into consideration in the choice of treatment. However, less intensive use of radiotherapy, chemotherapy, or surgery, as well as targeted multimodal therapeutic approaches, is under research. This article summarizes the main events in the HPV life cycle, with emphasis on carcinogenic mechanisms and potential new molecular targets. Identifying distinct tumor entities of the oropharynx enables the design and development of new preventive and therapeutic strategies to reduce the incidence and mortality of HPV-associated oropharyngeal cancers in the near future.

Abstract
BACKGROUND Few human papillomavirus (HPV)(+) head and neck squamous cell carcinoma (HNSCC) cell lines exist. We established University of Michigan-squamous cell carcinoma-104 (UM-SCC-104), a new HPV(+) HNSCC cell line from a recurrent oral cavity tumor, and characterized it for the presence of cancer stem cells (CSCs). METHODS Tumor cells were tested for biomarker expression by immunohistology, and the presence of HPV was assessed by several methods. RESULTS UM-SCC-104 has a unique genotype, contains HPV-16, and expresses E6/E7. Inoculation of aldehyde dehydrogenase (ALDH)(+) and ALDH(-) cells in an immunocompromised mouse resulted in tumor growth from the ALDH(+) cells after 6 weeks that recapitulated the histology of the primary, whereas ALDH(-) cells did not produce tumors. CONCLUSION UM-SCC-104, a new HPV-16, CSC-containing HNSCC cell line will aid in studying recurrent HPV(+) tumors. The aggressive nature of this tumor is consistent with high uniform expression of epidermal growth factor receptor (EGFR) and a functionally significant proportion of ALDH(+) CSCs.

Lack of association of cadherin expression and histopathologic type, metastasis, or patient outcome in oropharyngeal squamous cell carcinoma: a tissue microarray study. Head Neck Pathol 2011; 6:38-47. [PMID: 22072429 PMCID: PMC3311946 DOI: 10.1007/s12105-011-0306-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2011] [Accepted: 10/21/2011] [Indexed: 10/15/2022]
Abstract
Altered cadherin expression is important for metastasis in many carcinomas including head and neck squamous cell carcinoma (SCC). We evaluated E- and N-cadherin expression specifically in oropharyngeal SCC and correlated this with clinical and pathologic features. Oropharyngeal SCC patients with clinical follow up information were identified from clinician databases from 1996 through 2007 and tissue microarrays created. Tumors had been previously typed histopathologically as keratinizing, non-keratinizing, or non-keratinizing with maturation, and had known p16 and human papillomavirus status, respectively. Immunohistochemistry was performed on the microarrays, and staining was evaluated for presence and intensity (0 = negative, 1 = weak, 2 = moderate, 3 = strong) both visually and also with digital image analysis software. Of 154 cases, E-cadherin was expressed in 152 (98.7%) and N-cadherin in 17 (11.5%). Neither E- nor N-cadherin expression was statistically significantly associated with histopathologic type (P = 0.082 and P = 0.228, respectively). E-cadherin staining intensity was not statistically significantly associated with nodal or distant metastasis, either visually or by image analysis, (P = 0.098 and P = 0.963 respectively) nor was N-cadherin (P = 0.228 and P = 0.935 respectively). Neither E- nor N-cadherin expression was associated with death from disease (P = 0.995; P = 0.964, respectively). E-cadherin is extensively expressed by oropharyngeal SCC, even the non-keratinizing type. Our results suggest that cadherin expression may not be a predictor for nodal or distant metastasis in these tumors. Mechanisms independent of cadherin expression may be important for metastases in oropharyngeal SCC.

Abstract
Oncogenic human papillomavirus (HPV) is currently recognised as a major risk factor for the development of head and neck squamous cell carcinomas (HNSCC). HPV is mostly detected in tumours arising from the oropharynx and more specifically from the tonsil. HPV-related tumours display clinical and molecular characteristics that are distinct from HPV-unrelated tumours, which are generally induced by alcohol and tobacco abuse. Detection of biologically active HPV in HNSCC has prognostic relevance, which warrants the separate classification of HPV-induced tumours and is a prerequisite for further optimisation of treatment protocols for this distinct group. Current guidelines for the treatment of oropharyngeal squamous cell carcinoma (OPSCC) have not incorporated specific treatment modalities for HPV-related tumours. The development of such treatment options is still in a preclinical phase or in early clinical trials. Recent data on treatment response of OPSCC have been obtained by retrospectively analysing HPV-status and indicate that patients with HPV-related tumours show a favourable prognosis, independent of the type of treatment. These patients may benefit from de-intensified treatment, which should be assessed in prospective clinical trials. The development and future use of new antiviral and immunomodulatory therapeutics may be instrumental in this approach to improve survival rates and decrease disease-and-treatment-related morbidity. In this review we will focus on present therapeutic HPV-targeting strategies and discuss future directions for de-intensified treatment of HPV-positive HNSCC.
