Same type of cancer [49,53,56]. This study identified two overexpressed genes, ANXA1 and p16, in penile squamous cell carcinoma positive for high-risk HPVs. To the best of our knowledge this report is the first to describe ANXA1 protein overexpression in penile carcinoma with high-risk HPV independently of the subtype. These genes are associated with various physiological processes including cellular differentiation, cell proliferation and signal transduction, suggesting that they have an important role in penile carcinogenesis. However, additional studies are required in order to elucidate their specific role in penile cancer with high-risk HPV.Author ContributionsConceived and designed the experiments: MFC LLV SMO PR.

As SIS3 alternatives to surgical resection, minimally invasive tumor ablation therapies such as radiofrequency, laser, microwave and cryoablation have been developed for the treatment of benign or malignant tumors, and these techniques can 25331948 be used to ablate undesirable tissue in a well-controlled and precise way [1?]. Most of these therapies are based on thermal ablation techniques that destroy the tumor tissue by increasing or decreasing temperatures to induce irreversible cellular injury. Recently, irreversible electroporation (IRE) has begun receiving attention as a relative newcomer to the field of tumor ablation techniques in focal treatment. IRE is used to apply short length but high voltage electrical pulses to the cell, generating a destabilizing electric potential and causing the formation of permanent nanoscale defects in the cell membrane. The permanent permeability of cell membrane leads to changes in cell homeostasis and cell death [4,5]. IRE lacks many of the drawbacks of other conventional thermal ablation methods, including tumor protection next tolarge vessels due to a heat sink effect and the associated destruction of normal structures [6]. Our previous research also indicated that nerves treated with IRE can attain full recovery [7]. Many encouraging results have been reported in the IRE treatment of solid tumors in humans, including lung, prostate, kidney, and liver buy SC-1 cancers [8?0]. Human treatment has revealed that IRE is a feasible and safe technique that could offer some potential advantages over current thermal ablation techniques. It is thought that IRE achieves focal tumor ablation by destabilizing the cell membrane and inducing cell death in a non-thermal manner. Thus, many autologous tumor-antigens will remain in situ after IRE treatment, and there remains a question of whether IRE of solid tumors could evoke an immune response. The only immunohistochemical study focusing on immune response to tumor ablation with IRE used immunohistochemistry to show that there was no recruitment of immune cells such as CD4+, CD8+ T lymphocytes, macrophages, activated antigen presenting cells (APCs) and dendritic cells after 72 hoursImmunologic Response to IRE[11]. However, many other aspects of immune responses, such as changes in cytokines peripheral and intratumoral immune cell subsets and specific antitumor activity remain to be clarified. In this study, we aimed to explore the immunologic response to tumor ablation with IRE using a subcutaneously xenotransplanted osteosarcoma model in rats and to provide experimental.Same type of cancer [49,53,56].
