He is also co-director of the UConn Musculoskeletal Institute of the Department of Orthopaedic Surgery\u00a0at UConn Health.<\/p>\n<p>Canalis is an internationally renowned physician-scientist in bone metabolism. His laboratory is known for the discovery of skeletal growth factors and has pursued important investigations on the role of growth factors and their antagonists in skeletal function.\u00a0 His lab has made seminal contributions to our understanding of the mechanisms of glucocorticoid action in bone in an effort to explain the pathogenesis of glucocorticoid induced osteoporosis and correct the disease.\u00a0 The laboratory\u2019s recent work has centered on factors determining osteoblast and osteoclast cell fate and function.<\/p>\n<p>These investigations include studies on the role of Notch signaling in osteoblast and osteoclast cell differentiation.\u00a0 Cellular and genetically engineered mouse models are used for the research conducted by the group.\u00a0 The laboratory is particularly interested in translational research and has created genetically engineered mouse models of Hajdu Cheney Syndrome and Lateral Meningocele Syndrome, devastating diseases characterized by bone loss and fractures.\u00a0 The studies have allowed the team to determine mechanisms of the bone loss and are exploring ways to prevent the skeletal disease. Recently, a mouse model of non-classical osteogenesis imperfecta was created. These mouse lines have allowed the study of mechanisms relevant to disease pathogenesis and the development of novel therapeutic avenues, including the use of antisense oligonucleotides.<\/p>\n<p>As part of Canalis\u2019 recent work, the laboratory investigated the mechanisms that lead to the formation of cortical bone during early life, but with an impact on skeletal health throughout the life of the individual. Impaired formation of cortical bone could lead to bone fragility and fractures later in life. The findings of this work formed the basis of the abstract presented at the 2025 annual meeting of the ASBMR.<\/p>\n<p>The Canalis laboratory has been continuously funded by the National Institutes of Health (NIH) since 1981. In 1990 it received a MERIT Award from the National Institute of Musculoskeletal and Skin Disorders (NIAMS).\u00a0 Currently, the laboratory is funded by NIAMS.<\/p>\n<aside class=\"grey-sidebar full-sidebar\">\n  <\/p>\n<p><strong>The 2025 ASBMR Most Outstanding Basic Abstract by Dr. Ernesto Canalis:<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>Notch receptors (1 through 4) are critical determinants of cell differentiation and function in the skeleton. NOTCH3 is structurally distinct and has a well-defined pattern of cellular expression, in smooth muscle vascular cells and osteocytes, conferring this Notch receptor a unique role in physiology. Corticalization is a poorly understood process, when trabeculae coalesce to consolidate as cortical bone in early life, but with an impact on skeletal integrity that is sustained throughout life.<\/p>\n<p>Failure to form cortical bone results in pronounced skeletal fragility. In the present study, we used conditional mouse models of the biologically active NOTCH3 intracellular domain (N3ICD) expression (R26-N3ICD), where sequences coding for the N3ICD are cloned into the\u00a0Rosa26\u00a0locus downstream of a\u00a0loxP\u00a0flanked STOP cassette, so that Cre recombination allows for the expression of the N3ICD. Constitutive\u00a0BGLAP-Cre\u00a0and\u00a0Dmp1-Cre\u00a0mice and inducible\u00a0Dmp1-CreER<sup>T2<\/sup>\u00a0mice were crossed with\u00a0R26-N3ICD\u00a0mice to activate NOTCH3 signaling.\u00a0BGLAP-Cre;\u00a0and\u00a0Dmp1-Cre;R26-N3ICD\u00a0mice did not form cortical bone and displayed skeletal fragility, increased intracortical remodeling and cortical porosity, reflecting a bone structure that failed to mature as cortical pores close during the maturation process. The cortical phenotype was sustained and observed at 1, 3 and 6 months of age and was present when the N3ICD was induced postnatally following tamoxifen administration to\u00a0Dmp1-CreER<sup>T2<\/sup>\u00a0crossed with\u00a0R26-N3ICD\u00a0mice. Bulk RNASeq from\u00a0Dmp1-Cre;R26-N3ICD\u00a0osteocytes revealed a suppression of\u00a0Sp7, (essential for osteogenesis) and an induction of\u00a0Gzmb, encoding the protease granzyme B that prevents integrin binding, which is necessary for corticalization.<\/p>\n<p>Ingenuity pathway analysis revealed suppression of\u00a0Gata4, a factor required for skeletal development and mineralization. Single cell RNASeq of femoral bone from\u00a0Dmp1-Cre;R26-N3ICD\u00a0mice demonstrated an increase in endothelial and smooth muscle cell gene clusters suggesting that vascular invasion may contribute to the enhanced intracortical bone remodeling under NOTCH3 control.<\/p>\n<p>In conclusion, NOTCH3 is a critical signal in the regulation of corticalization, a poorly understood process that is essential to skeletal integrity and with a lifelong impact on bone health.<\/p>\n<p>&nbsp;<\/p>\n<p><\/aside>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><em>\u00a0<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>At ASBMR\u2019s Annual Meeting the Canalis Lab of UConn was honored with the 2025 ASBMR Most Outstanding Basic Abstract Award.<\/p>\n","protected":false},"author":98,"featured_media":235763,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_crdt_document":"","wds_primary_category":0,"wds_primary_series":0,"wds_primary_attribution":0,"footnotes":""},"categories":[2429,2287,2076,1868,2233],"tags":[],"magazine-issues":[],"coauthors":[1873],"class_list":["post-235759","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-awards-scholarships","category-orthopedics","category-research","category-meds","category-university-news"],"pp_statuses_selecting_workflow":false,"pp_workflow_action":"current","pp_status_selection":"publish","acf":[],"publishpress_future_action":{"enabled":false,"date":"2026-05-03 05:41:44","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/235759","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/users\/98"}],"replies":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/comments?post=235759"}],"version-history":[{"count":7,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/235759\/revisions"}],"predecessor-version":[{"id":235769,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/235759\/revisions\/235769"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media\/235763"}],"wp:attachment":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media?parent=235759"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/categories?post=235759"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/tags?post=235759"},{"taxonomy":"magazine-issue","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/magazine-issues?post=235759"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/coauthors?post=235759"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
