In this in vitro study, H1299 lung cells and BV-2 microglial cells were exposed to the hypoxia-like effect of CoCl2 with or without PK 11195. Exposing the H1299 cells to 0.5 mM CoCl2 for 24 h resulted in decreases in cell viability (63%, p &lt; 0.05), elevation of cardiolipin peroxidation levels (38%, p &lt; 0.05), mitochondrial membrane potential depolarization (13%, p &lt; 0.001), and apoptotic cell death (117%, p &lt; 0.05). Pretreatment with PK 11195 (25 \u00b5M) exhibited significant protective capacity on CoCl2-induced alterations in the mentioned processes. Exposure of BV-2 cells to increasing concentrations of CoCl2 (0.3, 0.5, 0.7 mM) for 4 h resulted in alterations in the same cellular processes. These alterations were obtained in a dose-dependent manner, except the changes in caspases 3 and 9. The novel ligands as well as PK 1195 attenuated the in vitro hypoxia-like effects of CoCl2. It appears that the TSPO ligand PK 11195 can prevent CoCl2-induced cellular damage in both non-neuronal and brain cell lines, and they may offer a novel approach to the treatment of hypoxia-related lung and brain diseases in some cases that fail to respond to conventional therapies.<\/jats:p>","DOI":"10.3390\/biom12101397","type":"journal-article","created":{"date-parts":[[2022,9,29]],"date-time":"2022-09-29T21:03:10Z","timestamp":1664485390000},"page":"1397","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Effect of the Classical TSPO Ligand PK 11195 on In Vitro Cobalt Chloride Model of Hypoxia-like Condition in Lung and Brain Cell Lines"],"prefix":"10.3390","volume":"12","author":[{"given":"Rula","family":"Amara","sequence":"first","affiliation":[{"name":"Ruth and Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa 31096, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4393-8739","authenticated-orcid":false,"given":"Nidal","family":"Zeineh","sequence":"additional","affiliation":[{"name":"Ruth and Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa 31096, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheelu","family":"Monga","sequence":"additional","affiliation":[{"name":"Ruth and Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa 31096, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9765-8938","authenticated-orcid":false,"given":"Abraham","family":"Weizman","sequence":"additional","affiliation":[{"name":"Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Research Unit, Geha Mental Health Center and Felsenstein Medical Research Center, Petah Tikva 4910002, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moshe","family":"Gavish","sequence":"additional","affiliation":[{"name":"Ruth and Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa 31096, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"657","DOI":"10.3892\/ol_00000115","article-title":"Role and Mechanism of Hypoxia-Inducible Factor-1 in Cell Growth and Apoptosis of Breast Cancer Cell Line MDA-MB-231","volume":"1","author":"Shi","year":"2010","journal-title":"Oncol.
