Prognostic and Clinicopathological Significance of FADD Upregulation in Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis.

ABSTRACT: Fas-associated death domain (FADD) upregulation, i.e., gene amplification, protein phosphorylation and/or overexpression, has shown promising prognostic implications in head and neck squamous cell carcinoma (HNSCC). This systematic review and meta-analysis aims to evaluate the clinicopathological and prognostic significance of FADD upregulation in HNSCC. We searched studies published before February 2020 through PubMed, Embase, Web of Science, Scopus and Google Scholar. We evaluated the quality of the studies included using the QUIPS tool. The impact of FADD upregulation on survival and clinicopathological variables was meta-analysed. We explored heterogeneity and their sources, conducted sensitivity analyses and investigated small-study effects. Thirteen studies (1,923 patients) met inclusion criteria. FADD immunohistochemical overexpression was statistically associated with worse overall survival (hazard ratio [HR] = 1.52, 95% confidence intervals [CI] = 1.28-1.81, p < 0.001), disease-specific survival (HR = 2.52, 95% CI = 1.61-3.96, p < 0.001), disease-free survival (HR = 1.67, 95% CI=1.29-2.15, p < 0.001), higher clinical stage (odds ratio [OR] = 1.72, 95% CI = 1.17-2.51, p = 0.005) and a large magnitude of effect with N+ status (OR = 2.36, 95% CI = 1.85-3.00, p < 0.001). FADD phosphorylation in ser-194 demonstrated no prognostic value, while no conclusive results can be drawn for FADD gene amplification. In conclusion, our findings indicate that immunohistochemical assessment of FADD overexpression could be incorporated into the prognostic evaluation of HNSCC.

Project description:ObjectiveForkhead box O 4 (FOXO4), a key albumen in the forkhead box O (FOXOs) family, plays crucial roles as a tumor suppressor in the cancer development. In our previous study, Peroxiredoxin1 (Prx1) promoted the development of oral cancer and was predicted to bind to FOXO4. The aim of this study was to investigate the clinicopathological significance of FOXO4 expression and its potential mechanism in head and neck squamous cell carcinomas (HNSCC).MethodsThe function of FOXO4 correlation with HNSCC prognosis was analyzed via ONCOMINE, UALCAN, Human Protein Atlas, and cBioPortal. The expression of FOXO4 was detected in Prx1 silenced CaL27 and SCC9 cell lines by Western blot. FOXO4 protein expression was observed via immunohistochemistry (IHC) and the binding of Prx1 to FOXO4 measured by Duolink analysis in a 4-nitro-quinoline-1-oxide- (4NQO-) induced tongue carcinogenesis model in Prx1+/+ and Prx1+/- mice.ResultsBy the analysis of Bioinformation Databases, there was a significant interaction of FOXO4 down expression to clinical tumor stages and pathological grades in the patients with HNSCC. Reduced mRNA and protein expression of FOXO4 were found to be significantly correlated with the poor overall survival (OS) of HNSCC patients. FOXO4 expression is negatively related to Prx1 significantly in HNSCC tissues. By employing a 4NQO-induced oral carcinogenesis mouse model, we confirmed that FOXO4 expression was reduced in 4NQO-induced squamous cell carcinoma (SCC) tongue tissues compared with those in normal tissues. Prx1 knockdown resulted in the upregulation of FOXO4 expression in the SCC tissues and CaL27 and SCC9 cell lines. Furthermore, the interaction of Prx1 with FOXO4 was observed in mouse tongue tissues by Duolink analysis.ConclusionFOXO4 plays an important role in the development of HNSCC. The lower expression of FOXO4 is significantly correlated with the shorter OS in patients with HNSCC. FOXO4 is negatively regulated via interaction with Prx1. FOXO4 could be a potential molecular target for the treatment and prognosis of HNSCC.

Project description:Background/aimHead and neck squamous cell carcinoma (HNSCC) has poor prognosis, with survival rates that have not significantly improved over the past several decades. Therefore, prediction of HNSCC prognosis is of clinical importance. Baculoviral IAP Repeat containing 2 (BIRC2) and Baculoviral IAP Repeat containing 3 (BIRC3) are involved in oncogenic activity by modulating cell proliferation, apoptosis and invasion in HNSCC. This study aimed to develop and validate a predictive gene signature for BIRC2 and BIRC3.Materials and methodsThe genomic copy number and gene expression for BIRC2 and BIRC3 were systematically explored in patients with HNSCC to investigate the clinical relevance of BIRC2 and BIRC3 activation. A prognostic signature was developed based on correlations associated with BIRC2 and BIRC3 mRNA expression and copy number alterations. Hierarchical clustering was used to classify the clusters (Clusters 1 and 2). Moreover, independent validation of the BIRC2-BIRC3 gene signature was performed using the Leipzig, MDACC, FHCRC, and KHU datasets. To explore the biological functions of the BIRC2-BIRC3 gene signature, string analysis and pathway annotation were also performed.ResultsBIRC2-BIRC3 gene signature-derived cluster 2 patients exhibited significantly poor survival. This signature also predicted survival in three independent cohorts. Interestingly, the BIRC2-BIRC3 gene signature additionally permitted the identification of survival in advanced tumor stages with excellent accuracy in all three cohorts. Multivariate Cox regression analysis identified that the BIRC2-BIRC3 signature was an independent predictor associated with the survival of patients with HNSCC. Moreover, Inhibition of BIRC2 modulated the NF-B signaling pathway via upregulation of CBR1 expression.ConclusionThe BIRC2-BIRC3 gene signature was found to be associated with the prognosis of HNSCC. Thus, BIRC2 and BIRC3 could be potential targets for improving HNSCC prognosis.
