Penile cancer affects predominantly men aged between 50 and 70 years [1?]. Penile cancer is associated with several established risk factors and associated diseases 
including phimosis with chronic inflammation, human papillomavirus (HPV) infection, poor hygiene and smoking [4]. Studies reported an overall HPV prevalence of, approximately, 48 in penile cancer worldwide [5,6]. In penile carcinomas the most common HPV types are HPV 16 and HPV 18. HPV 16 is most prevalent in North America, Europe, South America and India [5,7]. HPV contributes to tumorigenesis predominantly through the action of viral oncoproteins (E6 and E7) [8]. E6 inhibits apoptotic signaling in response to growth-suppressive cytokines by interacting with tumor necrosis factor (TNF)-a receptor TNFR1, FASassociated 498-02-2 biological activity protein with death domain (FADD) and caspase 8, and via degradation of pro-apoptotic BAX and BAK. E6-mediated degradation of PDZ proteins leads to a loss of cell polarity and 15481974 induces hyperplasia [9,10]. Therefore, E6 can interfere with the regulation of expression of genes by interacting with and bindingto the proteins mentioned above, prompting the interest of some researchers in identifying new genes whose expression can be disturbed by E6 protein. One gene that could be subject to regulation by the oncoprotein E6 is ANXA1 as previously suggested by Shimoji et al., 2009 [11]. The annexin superfamily proteins have been implicated in several cellular processes including differentiation, apoptosis, proliferation and inflammation. The expression of ANXA1 has been studied in various types of cancer, but there is no consensus concerning the role this protein plays during tumor initiation and/or progression. Some studies observed a correlation between the decrease of ANXA1 mRNA and protein with esophageal, prostate and breast cancers [12?5]. On the contrary, others studies showed the overexpression of ANXA1 in head and neck and pancreatic cancers [16,17]. Here, we aimed to identify novel genes differentially expressed in penile squamous cell carcinoma positive for high-risk HPVs and evaluate a possible correlation between HPV positivity, the expression of the genes and the subtypes of penile squamous cell carcinoma.ANXA1 Overexpression in HPV Positive Penis CancerMaterials and Methods PatientsArchival paraffin wax-embedded tissue sections from 47 penile squamous cell carcinoma were obtained and reviewed by a pathologist, with approval from the Research Ethics Committee of the College of Medicine of Sao Jose do Rio Preto, Research ?Ethics Committee of Hospital A.
