However, recently, more attention has been paid to their role in the pathogenesis of different diseases as well as tumorigenesis, invasion and metastases. The expression pattern and possible role of connexins (Cxs), as major GJ proteins, under both physiological and pathological conditions in the adrenal gland, were evaluated in this review. The databases Web of Science, PubMed and Scopus were searched. Studies were evaluated if they provided data regarding the connexin expression pattern in the adrenal gland, despite current knowledge of this topic not being widely investigated. Connexin expression in the adrenal gland differs according to different parts of the gland and depends on ACTH release. Cx43 is the most studied connexin expressed in the adrenal gland cortex. In addition, Cx26, Cx32 and Cx50 were also investigated in the human adrenal gland. Cx50 as the most widespread connexin, along with Cx26, Cx29, Cx32, Cx36 and Cx43, has been expressed in the adrenal medulla with distinct cellular distribution. Considerable effort has recently been directed toward connexins as therapeutically targeted molecules. At present, there exist several viable strategies in the development of potential connexin-based therapeutics. The differential and hormone-dependent distribution of gap junctions within adrenal glands, the relatively large gap junction within this gland and the increase in the gap junction size and number following hormonal treatment would indicate that gap junctions play a pivotal role in cell functioning in the adrenal gland.<\/jats:p>","DOI":"10.3390\/ijms25105399","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T11:31:52Z","timestamp":1715772712000},"page":"5399","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Role of the Gap Junction Protein Connexin in Adrenal Gland Tumorigenesis"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2112-004X","authenticated-orcid":false,"given":"Maja","family":"Mizdrak","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, University Hospital of Split, 21000 Split, Croatia"},{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tina","family":"Ticinovic Kurir","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University Hospital of Split, 21000 Split, Croatia"},{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Mizdrak","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9696-3359","authenticated-orcid":false,"given":"Marko","family":"Kumric","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"},{"name":"Laboratory for Cardiometabolic Research, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3676-1608","authenticated-orcid":false,"given":"Mladen","family":"Krnic","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University Hospital of Split, 21000 Split, Croatia"},{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1634-0635","authenticated-orcid":false,"given":"Josko","family":"Bozic","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"},{"name":"Laboratory for Cardiometabolic Research, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kutova, O.M., Pospelov, A.D., and Balalaeva, I.V.
