To ask how the Hippo pathway affects mineralized tissue homeostasis in a tissue that is highly reliant on a tight homeostatic control of mineralized deposition and resorption, we determined the effects of YAP\/TAZ dysregulation on the periodontal tissues alveolar bone, root cementum, and periodontal ligament. Loss of YAP\/TAZ was associated with a reduction of mineralized tissue density in cellular cementum and alveolar bone, a downregulation in collagen I, alkaline phosphatase, and RUNX2 gene expression, an increase in the resorption markers TRAP and cathepsin K, and elevated numbers of TRAP-stained osteoclasts. Cyclic strain applied to periodontal ligament cells resulted in YAP nuclear localization, an effect that was abolished after blocking YAP. The rescue of YAP signaling with the heparan sulfate proteoglycan agrin resulted in a return of the nuclear YAP signal. Illustrating the key role of YAP on mineralization gene expression, the YAP inhibition-related downregulation of mineralization-associated genes was reversed by the extracellular matrix YAP activator agrin. Application of the unopposed mouse molar model to transform the periodontal ligament into an unloaded state and facilitate the distal drift of teeth resulted in an overall increase in mineralization-associated gene expression, an effect that was 10\u201320% diminished in Wnt1Cre\/YAP\/TAZ mutant mice. The unloaded state of the unopposed molar model in Wnt1Cre\/YAP\/TAZ mutant mice also caused a significant three-fold increase in osteoclast numbers, a substantial increase in bone\/cementum resorption, pronounced periodontal ligament hyalinization, and thickened periodontal fiber bundles. Together, these data demonstrated that YAP\/TAZ signaling is essential for the microarchitectural integrity of the periodontium by regulating mineralization gene expression and preventing excessive resorption during bodily movement of the dentoalveolar complex.<\/jats:p>","DOI":"10.3390\/jdb10010014","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T08:17:03Z","timestamp":1646122623000},"page":"14","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["The Hippo Pathway Effectors YAP\/TAZ Are Essential for Mineralized Tissue Homeostasis in the Alveolar Bone\/Periodontal Complex"],"prefix":"10.3390","volume":"10","author":[{"given":"Mirali","family":"Pandya","sequence":"first","affiliation":[{"name":"Center for Craniofacial Research and Diagnosis, Texas A&M College of Dentistry, 3302 Gaston Avenue, Dallas, TX 75252, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gokul","family":"Gopinathan","sequence":"additional","affiliation":[{"name":"Center for Craniofacial Research and Diagnosis, Texas A&M College of Dentistry, 3302 Gaston Avenue, Dallas, TX 75252, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Connie","family":"Tillberg","sequence":"additional","affiliation":[{"name":"Center for Craniofacial Research and Diagnosis, Texas A&M College of Dentistry, 3302 Gaston Avenue, Dallas, TX 75252, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6874-9331","authenticated-orcid":false,"given":"Jun","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, McGovern Medical School, The University of Texas Health Science Center at Houston, 6431 Fannin Street, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianghong","family":"Luan","sequence":"additional","affiliation":[{"name":"Center for Craniofacial Research and Diagnosis, Texas A&M College of Dentistry, 3302 Gaston Avenue, Dallas, TX 75252, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3356-9677","authenticated-orcid":false,"given":"Thomas G.
