Furthermore, PXR activity relates to that of other NRs, such as constitutive androstane receptor (CAR), through a crosstalk that in turn orchestrates a complex network of responses. Thus, besides regulating DMETs, PXR signaling is involved in both liver damage progression and repair and in the neoplastic transition to hepatocellular carcinoma. We here summarize the present knowledge about PXR expression and function in chronic liver diseases characterized by different etiologies and clinical outcome, focusing on the molecular pathways involved in PXR activity. Although many molecular details of these finely tuned networks still need to be fully understood, we conclude that PXR and its modulation could represent a promising pharmacological target for the identification of novel therapeutical approaches to chronic liver diseases.<\/jats:p>","DOI":"10.3390\/cells11010061","type":"journal-article","created":{"date-parts":[[2021,12,28]],"date-time":"2021-12-28T01:18:15Z","timestamp":1640654295000},"page":"61","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["The Nuclear Receptor PXR in Chronic Liver Disease"],"prefix":"10.3390","volume":"11","author":[{"given":"Katia","family":"Sayaf","sequence":"first","affiliation":[{"name":"Department of Surgery, Oncology and Gastroenterology, University of Padova, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Zanotto","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical and Pharmacological Sciences, University of Padova, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4127-8941","authenticated-orcid":false,"given":"Francesco Paolo","family":"Russo","sequence":"additional","affiliation":[{"name":"Department of Surgery, Oncology and Gastroenterology, University of Padova, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2247-8227","authenticated-orcid":false,"given":"Daniela","family":"Gabbia","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical and Pharmacological Sciences, University of Padova, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6398-8237","authenticated-orcid":false,"given":"Sara","family":"De Martin","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical and Pharmacological Sciences, University of Padova, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/j.apsb.2019.06.012","article-title":"PXR: A Center of Transcriptional Regulation in Cancer","volume":"10","author":"Xing","year":"2020","journal-title":"Acta Pharm.
