Gingival hyperplasia could occur after the administration of cyclosporine A. Up to 90% of the patients submitted to immunosuppressant drugs have been reported to suffer from this side effect. The role of fibroblasts in gingival hyperplasia has been widely discussed by literature, Gingival overgrowth is a side effect of certain medications. The most fibrotic drug-induced lesions develop in response to therapy with phenytoin, the least fibrotic lesions are caused by cyclosporin A, and the intermediate fibrosis occurs in nifedipine-induced gingival overgrowth. Fibrosis is one
Few studies have investigated the role of extracellular-matrix proteoglycans in the pathogenesis of drug-induced gingival overgrowth (DIGO). SPOCK1 is an extracellular proteoglycan that induces epithelial to mesenchymal transition (EMT) in several cancer cell lines and exhibits protease-inhibitory
BACKGROUND
Gingival overgrowth is a common side-effect following administration of cyclosporin A. We reported previously that lysosomal protease cathepsin-L activity, but not cathepsin-B, was significantly suppressed by short-term cyclosporin A exposure in human gingival fibroblasts. Although this
We report one case of ligneous periodontitis, which is a clinical sign of hypoplasmino-genemia. It appears as massive, painless ulcerated gingival enlargements and alveolar bone destruction in the affected area. The course of the disease is progressive and typically ends with early loss of teeth. At
BACKGROUND
Connective tissue growth factor (CTGF/CCN2), associated with multiple human fibrotic diseases, is overexpressed in the tissue of gingival overgrowth. Although surgical excision is the current treatment modality for gingival overgrowth, the recurrent rate is high despite proper recall
Transforming growth factor β (TGFβ) regulates cell proliferation, differentiation, migration, apoptosis, and extracellular matrix production. It also plays a pivotal role in the pathogenesis of gingival overgrowth. Thrombin is a key player in tissue repair, remodeling, and fibrosis after an injury,
OBJECTIVE
Many fibrotic processes are associated with an increased level of transforming growth factor-β1 (TGF-β1). TGF-β1 can increase synthesis of matrix proteins and enhance secretion of protease inhibitors, resulting in matrix accumulation. Connective tissue growth factor (CTGF) is a downstream
