To overcome these limitations, we propose that elucidation and pharmacologic targeting of host cell Master Regulator proteins\u2014whose aberrant activities govern the reprogramed state of infected-coronavirus cells\u2014presents unique opportunities to develop novel mechanism-based therapeutic approaches to antiviral therapy, either as monotherapy or as a complement to established treatments. Specifically, we propose that a small module of host cell Master Regulator proteins (ViroCheckpoint) is hijacked by the virus to support its efficient replication and release. Conventional methodologies are not well suited to elucidate these potentially targetable proteins. By using the VIPER network-based algorithm, we successfully interrogated 12h, 24h, and 48h signatures from Calu-3 lung adenocarcinoma cells infected with SARS-CoV, to elucidate the time-dependent reprogramming of host cells and associated Master Regulator proteins. We used the NYS CLIA-certified Darwin OncoTreat algorithm, with an existing database of RNASeq profiles following cell perturbation with 133 FDA-approved and 195 late-stage experimental compounds, to identify drugs capable of virtually abrogating the virus-induced Master Regulator signature. This approach to drug prioritization and repurposing can be trivially extended to other viral pathogens, including SARS-CoV-2, as soon as the relevant infection signature becomes available.<\/jats:p>","DOI":"10.1101\/2020.05.12.091256","type":"posted-content","created":{"date-parts":[[2020,5,17]],"date-time":"2020-05-17T22:54:31Z","timestamp":1589756071000},"source":"Crossref","is-referenced-by-count":15,"title":["The Host Cell ViroCheckpoint: Identification and Pharmacologic Targeting of Novel Mechanistic Determinants of Coronavirus-Mediated Hijacked Cell States"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1469-4704","authenticated-orcid":false,"given":"Pasquale","family":"Laise","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gideon","family":"Bosker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1622-5840","authenticated-orcid":false,"given":"Xiaoyun","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4472-9632","authenticated-orcid":false,"given":"Yao","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3418-9203","authenticated-orcid":false,"given":"Eugene F.","family":"Douglass","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4012-8677","authenticated-orcid":false,"given":"Charles","family":"Karan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7072-0810","authenticated-orcid":false,"given":"Ronald B.","family":"Realubit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7731-7848","authenticated-orcid":false,"given":"Sergey","family":"Pampou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4742-3679","authenticated-orcid":false,"given":"Andrea","family":"Califano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7503-2491","authenticated-orcid":false,"given":"Mariano J.","family":"Alvarez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024080404475724000_2020.05.12.091256v1.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra032498"},{"key":"2024080404475724000_2020.05.12.091256v1.2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2001017"},{"key":"2024080404475724000_2020.05.12.091256v1.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)13413-7"},{"key":"2024080404475724000_2020.05.12.091256v1.4","doi-asserted-by":"publisher","DOI":"10.1038\/sj.emboj.7600640"},{"key":"2024080404475724000_2020.05.12.091256v1.5","doi-asserted-by":"publisher","DOI":"10.1038\/nrd.2015.37"},{"key":"2024080404475724000_2020.05.12.091256v1.6","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.6019"},{"key":"2024080404475724000_2020.05.12.091256v1.7","unstructured":"NIAID.
