Zebrafish sweetbread (swd) mutants develop hypoplastic acini and dysmorphic ducts in the exocrine pancreas, with impeded progression of cell division cycle and of epithelial growth. Positional cloning and allelic complementation have revealed that the swd mutations affect the transient receptor potential melastatin-subfamily member 7 (trpm7) gene, which encodes a divalent cation-permeable channel with kinase activity. Supplementary Mg2+ partially rescued the exocrine pancreatic defects of the trpm7 mutants by improving cell-cycle progression and growth and repressing the suppressor of cytokine signaling 3a (socs3a) gene. The role of Socs3a in Trpm7-mediated signaling is supported by the findings that socs3a mRNA level is elevated in the trpm7 mutants, and antisense inhibition of socs3a expression improved their exocrine pancreatic growth. TRPM7 is generally overexpressed in human pancreatic adenocarcinoma. TRPM7-deficient cells are impaired in proliferation and arrested in the G0-G1 phases of the cell division cycle. Supplementary Mg2+ rescued the proliferative defect of the TRPM7-deficient cells. Results of this study indicate that Trpm7 regulates exocrine pancreatic development via the Mg2+-sensitive Socs3a pathway, and suggest that aberrant TRPM7-mediated signaling contributes to pancreatic carcinogenesis.<\/jats:p>","DOI":"10.1242\/dmm.004564","type":"journal-article","created":{"date-parts":[[2010,12,23]],"date-time":"2010-12-23T23:17:08Z","timestamp":1293146228000},"page":"240-254","source":"Crossref","is-referenced-by-count":95,"title":["Transient receptor potential ion channel Trpm7 regulates exocrine pancreatic epithelial proliferation by Mg2+-sensitive Socs3a signaling in development and cancer"],"prefix":"10.1242","volume":"4","author":[{"given":"Nelson S.","family":"Yee","sequence":"first","affiliation":[{"name":"Division of Hematology, Oncology, and Blood & Marrow Transplantation, Department of Internal Medicine, Carver College of Medicine, University of Iowa, Iowa City, IA 52242, USA"},{"name":"Program of Cancer Signaling and Experimental Therapeutics, Holden Comprehensive Cancer Center, University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiqiang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Division of Hematology, Oncology, and Blood & Marrow Transplantation, Department of Internal Medicine, Carver College of Medicine, University of Iowa, Iowa City, IA 52242, USA"},{"name":"Program of Cancer Signaling and Experimental Therapeutics, Holden Comprehensive Cancer Center, University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I-Chau","family":"Liang","sequence":"additional","affiliation":[{"name":"Division of Hematology, Oncology, and Blood & Marrow Transplantation, Department of Internal Medicine, Carver College of Medicine, University of Iowa, Iowa City, IA 52242, USA"},{"name":"Program of Cancer Signaling and Experimental Therapeutics, Holden Comprehensive Cancer Center, University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042612500497900_b1-0040240","doi-asserted-by":"crossref","first-page":"863","DOI":"10.1016\/S0092-8674(03)01017-1","article-title":"A key role for TRPM7 channels in anoxic neuronal death","volume":"115","author":"Aarts","year":"2003","journal-title":"Cell"},{"key":"2021042612500497900_b2-0040240","doi-asserted-by":"crossref","first-page":"849","DOI":"10.1111\/j.1365-2184.2007.00476.x","article-title":"Importance of melastatin-like transient receptor potential 7 and cations (magnesium, calcium) in human osteoblast-like cell proliferation","volume":"40","author":"Abed","year":"2007","journal-title":"Cell Prolif."},{"key":"2021042612500497900_b3-0040240","doi-asserted-by":"crossref","first-page":"C360","DOI":"10.1152\/ajpcell.00614.2008","article-title":"Importance of melastatin-like transient receptor potential 7 and magnesium in the stimulation of osteoblast proliferation and migration by platelet-derived growth factor","volume":"297","author":"Abed","year":"2009","journal-title":"Am.
