PML results when oligodendrocytes within immunocompromised individuals are infected with the human JC virus (JCV). We have identified an oligodendrocyte precursor cell line, termed G144, that supports robust levels of JCV DNA replication, a central part of the JCV life cycle. In addition, we have determined that JC virus readily infects G144 cells. Furthermore, we have determined that JCV DNA replication in G144 cells is stimulated by myristoylated (i.e., constitutively active) Akt and reduced by the Akt-specific inhibitor MK2206. Thus, this oligodendrocyte-based model system will be useful for a number of purposes, such as studies of JCV infection, establishing key pathways needed for the regulation of JCV DNA replication, and identifying inhibitors of this process.<\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            The disease progressive multifocal leukoencephalopathy (PML) is caused by the infection of particular brain cells, termed oligodendrocytes, by the JC virus. Studies of PML, however, have been hampered by the lack of an immortalized human cell line derived from oligodendrocytes. Here, we report that the G144 oligodendrocyte cell line supports both infection by JC virus and robust levels of JCV DNA replication. Moreover, we have established that the Akt pathway regulates JCV DNA replication and that JCV DNA replication can be inhibited by MK2206, a compound that is specific for Akt. These and related findings suggest that we have established a powerful oligodendrocyte-based model system for studies of JCV-dependent PML.\n          <\/jats:p>","DOI":"10.1128\/jvi.00735-17","type":"journal-article","created":{"date-parts":[[2017,8,3]],"date-time":"2017-08-03T00:30:33Z","timestamp":1501720233000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Replication of JC Virus DNA in the G144 Oligodendrocyte Cell Line Is Dependent Upon Akt"],"prefix":"10.1128","volume":"91","author":[{"given":"Jesse N.","family":"Peterson","sequence":"first","affiliation":[{"name":"Department of Developmental, Molecular and Chemical Biology, Tufts University School of Medicine, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Developmental, Molecular and Chemical Biology, Tufts University School of Medicine, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong","family":"Shin","sequence":"additional","affiliation":[{"name":"Sackler Institute of Graduate Biomedical Sciences, New York University School of Medicine, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul J.","family":"Phelan","sequence":"additional","affiliation":[{"name":"Department of Developmental, Molecular and Chemical Biology, Tufts University School of Medicine, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip","family":"Tsichlis","sequence":"additional","affiliation":[{"name":"Molecular Oncology Research Institute, Tufts Medical Center, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James E.","family":"Schwob","sequence":"additional","affiliation":[{"name":"Department of Developmental, Molecular and Chemical Biology, Tufts University School of Medicine, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter A.","family":"Bullock","sequence":"additional","affiliation":[{"name":"Department of Developmental, Molecular and Chemical Biology, Tufts University School of Medicine, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(10)70040-5"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.05031-11"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrneurol.2010.164"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/839719"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-pathol-020712-164018"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa051847"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa051782"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-107-1-78"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.semcancer.2009.02.013"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/NEN.0b013e318180e631"},{"key":"e_1_3_2_12_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1097\/01.NT.0000459772.64925.38","article-title":"A new model of the pathology of the JC virus","volume":"18","author":"Valeo T","year":"2014","unstructured":"Valeo T . 2014.
