They have also been shown to play a role in genome hypermutation in several human cancers. An APOBEC3 hypermutation signature has been discovered in cervical cancer, which is intimately associated with infection by high-risk human papillomaviruses (HPVs). At the same time, HPV genomes themselves are subject to DNA editing by APOBECs. Similar to cervical cancer, a proportion of penile squamous cell carcinomas (SCCs) is etiologically driven by high-risk HPVs, but very little is known about the role of APOBECs in penile SCC development and progression.A series of 34 penile SCCs was analyzed for the expression of APOBEC3A protein by immunohistochemistry. HPV genotyping was carried out using a bead-based multiplex hybridization assay preceded by BSGP5+6+ primer-based amplification.We found a frequent reduction of APOBEC3A protein expression in the invasive parts of the majority of HPV-negative penile SCCs. In contrast, the majority of HPV-positive penile SCCs retained APOBEC3A expression during malignant progression.Our results suggest that APOBEC3A expression is downregulated during progression towards invasiveness in HPV-negative penile SCC, but maintained in HPV-positive penile SCC. How high-risk HPV-infected tumor cells tolerate high APOBEC3A, which appears to exert tumor suppressive functions in HPV-negative penile SCCs, remains to be elucidated. 000134852 536__ $$0G:(DE-HGF)POF3-317$$a317 - Translational cancer research (POF3-317)$$cPOF3-317$$fPOF III$$x0 000134852 588__ $$aDataset connected to CrossRef, PubMed, 000134852 7001_ $$0P:(DE-He78)83e1d0ede46be662d4a75f18e2dc7eec$$aPrigge, Elena-Sophie$$b1$$udkfz 000134852 7001_ $$aKaczorowski, Adam$$b2 000134852 7001_ $$0P:(DE-He78)11747cd1dc061b9333c0e3a3ff31bf2f$$avon Knebel Doeberitz, Magnus$$b3 000134852 7001_ $$aHohenfellner, Markus$$b4 000134852 7001_ $$aDuensing, Stefan$$b5 000134852 773__ $$0PERI:(DE-600)1483541-1$$a10.1159/000479007$$gVol. 85, no. 3, p. 169 - 178$$n3$$p169 - 178$$tPathobiology$$v85$$x1423-0291$$y2018 000134852 909CO $$ooai:inrepo02.dkfz.de:134852$$pVDB 000134852 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)83e1d0ede46be662d4a75f18e2dc7eec$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000134852 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)11747cd1dc061b9333c0e3a3ff31bf2f$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000134852 9131_ $$0G:(DE-HGF)POF3-317$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vTranslational cancer research$$x0 000134852 9141_ $$y2018 000134852 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000134852 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000134852 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPATHOBIOLOGY : 2015 000134852 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000134852 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000134852 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000134852 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000134852 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000134852 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000134852 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000134852 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences 000134852 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000134852 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000134852 9201_ $$0I:(DE-He78)G105-20160331$$kG105$$lGentherapie von Tumoren$$x0 000134852 980__ $$ajournal 000134852 980__ $$aVDB 000134852 980__ $$aI:(DE-He78)G105-20160331 000134852 980__ $$aUNRESTRICTED
