Interestingly, these enzymes can also play less expected roles in cell survival, polarity and motility via other substrates (e.g. receptors, chemokines), through an intracellular localization (e.g. the nucleus) or via non-catalytic functions. Most of these unconventional functions are yet to be functionally validated in a physiological context. Here, we used the delamination of the cephalic Neural Crest (NC) cells of the chicken embryo, a well described experimental model of epithelial-mesenchymal transition (EMT), to study the <em>in vivo</em> function of MMP14 (a.k.a MT1-MMP). MMP14 is a transmembrane MMP known for its importance in cell invasion and often associated with poor prognosis in cancer. We found that MMP14 is expressed and required for cephalic NC delamination. More specifically, MMP14 is necessary for the downregulation of Cadherin-6B and a co-inhibition of Cadherin-6B and MMP14 expressions is sufficient to restore NC delamination. Cadherin-6B is normally repressed by Snail2. Surprisingly, in MMP14 knockdown this lack of Cadherin-6B repression occurs in the context of a normal expression and nuclear import of Snail2. We further show that MMP14 is not detected in the nucleus and that Snail2 and MMP14 do not physically interact. These data reveals that a yet to be identified MMP14-dependent signaling event is required for the Snail2-dependent repression of Cadherin-6B. In conclusion, this work provides an <em>in vivo</em> example of atypical regulation of Cadherins by an MMP which emphasizes the importance and diversity of non-canonical functions of MMPs.</div></div>","PeriodicalId":50579,"journal":{"name":"Differentiation","volume":"142 ","pages":"Article 100836"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, cartilage is incapable of self-repair and any damage leads to degradation in osteoarthritis (OA). Autologous chondrocyte implantation therapies are currently being used to treat focal cartilage defects caused by post-traumatic OA (PTOA). For chondrocyte implantation, chondrocytes are isolated from healthy regions of cartilage from damaged joints, expanded on stiff polystyrene to increase cell number, and reimplanted into damaged areas to stimulate repair. Unfortunately, chondrocyte implantations can ultimately fail as chondrocytes dedifferentiate during expansion. In dedifferentiation, chondrocytes increase in size, elongate, and express contractile cytoskeletal molecules. Furthermore, cells produce a fibroblastic matrix which is biomechanically inferior to articular cartilage matrix. Therefore, developing a greater understanding of dedifferentiation is imperative. In the dedifferentiation process, cellular actin filaments reorganize from a cortical organization into stress fibers. The formation of stress fibers plays a crucial role in chondrocyte dedifferentiation by regulating chondrocyte cell morphology and gene expression. Determining the actin-based molecular underpinnings in chondrocyte dedifferentiation may enable the specific targeting of stress fibers to promote redifferentiation of passaged cells and improve chondrocyte implantation outcomes. This review focuses on how targeting regulators of actin filament organization may promote the redifferentiation of expanded chondrocytes for implantation, thus increasing potential therapeuticlongevity.</div></div>","PeriodicalId":50579,"journal":{"name":"Differentiation","volume":"143 ","pages":"Article 100847"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mutations in the genes that encode proteins responsible for cobalamin uptake, transport, or processing cause inborn errors of cobalamin metabolism, a group of disorders characterized by accumulation of homocysteine and methylmalonic acid, neurodevelopmental defects, ocular dysfunction, anemia, and failure to thrive. Mild to moderate craniofacial phenotypes have been observed but these phenotypes are not completely penetrant and have not been consistently recognized in the literature. However, in the most recent decade, animal models of <em>cblX</em> and <em>cblC</em>, two cobalamin disorder complementation groups, have documented craniofacial phenotypes. These data indicate a function for cobalamin in facial development. In this review, we performed a literature review of all cobalamin complementation groups to identify which groups, and which human variants, are associated with dysmorphic features, microcephaly, or marfanoid phenotypes. We identified dysmorphic facial features in <em>cblC</em>, <em>cblX</em>, <em>cblG</em>, <em>cblF</em>, and <em>cblJ</em>, which are caused by mutations in <em>MMACHC</em>, <em>HCFC1</em>, <em>MTR</em>, <em>LMBRD1</em>, and <em>ABCD4</em>, respectively. Other complementation groups were associated primarily with microcephaly. Animal models (zebrafish and mouse) of <em>cblC</em> and <em>cblX</em> support these clinical phenotypes and have demonstrated neural crest cell deficits that include reduced expression of <em>prdm1a</em>, <em>sox10</em>, and <em>sox9</em>, key molecular markers of neural crest development. Characterization of a zebrafish <em>mmachc</em> germline mutant also suggests atypical chondrocyte development.
