In the present study, we evaluated the role of CRY1 and CRY2 genes, and their potential interplay with HSD3B isoforms in adrenal pathophysiology in man. Forty-six sporadic aldosterone-producing adenomas (APAs) and 20 paired adrenal samples were included, with the human adrenocortical cells HAC15 used as the in vitro model. In our cohort of sporadic APAs, CRY1 expression was 1.7-fold [0.75\u20132.26] higher (p = 0.016), while CRY2 showed a 20% lower expression [0.80, 0.52\u20131.08] (p = 0.04) in APAs when compared with the corresponding adjacent adrenal cortex. Type II 3\u03b2-hydroxyl-steroid dehydrogenase (HSD3B2) was 317-fold [200\u2013573] more expressed than HSD3B1, and is the main HSD3B isoform in APAs. Both dehydrogenases were more expressed in APAs when compared with the adjacent cortex (5.7-fold and 3.5-fold, respectively, p &lt; 0.001 and p = 0.001) and HSD3B1 was significantly more expressed in APAs composed mainly of zona glomerulosa-like cells. Treatment with angiotensin II (AngII) resulted in a significant upregulation of CRY1 (1.7 \u00b1 0.25-fold, p &lt; 0.001) at 6 h, and downregulation of CRY2 at 12 h (0.6 \u00b1 0.1-fold, p &lt; 0.001), through activation of the AngII type 1 receptor. Independent silencing of CRY1 and CRY2 genes in HAC15 cells resulted in a mild upregulation of HSD3B2 without affecting HSD3B1 expression. In conclusion, our results support the hypothesis that CRY1 and CRY2, being AngII-regulated genes, and showing a differential expression in APAs when compared with the adjacent adrenal cortex, might be involved in adrenal cell function, and in the regulation of aldosterone production.<\/jats:p>","DOI":"10.3390\/ijms19061675","type":"journal-article","created":{"date-parts":[[2018,6,5]],"date-time":"2018-06-05T11:04:46Z","timestamp":1528196686000},"page":"1675","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Role of Cryptochrome-1 and Cryptochrome-2 in Aldosterone-Producing Adenomas and Adrenocortical Cells"],"prefix":"10.3390","volume":"19","author":[{"given":"Martina","family":"Tetti","sequence":"first","affiliation":[{"name":"Division of Internal Medicine and Hypertension, Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabella","family":"Castellano","sequence":"additional","affiliation":[{"name":"Division of Pathology, Department of Medical Sciences, University of Torino,10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7342-3421","authenticated-orcid":false,"given":"Francesca","family":"Veneziano","sequence":"additional","affiliation":[{"name":"Division of Pathology, Department of Medical Sciences, University of Torino,10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Corrado","family":"Magnino","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine and Hypertension, Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franco","family":"Veglio","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine and Hypertension, Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5480-1116","authenticated-orcid":false,"given":"Paolo","family":"Mulatero","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine and Hypertension, Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7322-2005","authenticated-orcid":false,"given":"Silvia","family":"Monticone","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine and Hypertension, Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1811","DOI":"10.1016\/j.jacc.2017.01.052","article-title":"Prevalence and Clinical Manifestations of Primary Aldosteronism Encountered in Primary Care Practice","volume":"69","author":"Monticone","year":"2017","journal-title":"J.
