Cholesterol depletion induces mesenchymal properties in oral squamous cell carcinoma cell line.

Background: Cholesterol in cell membranes is crucial for cell signaling, adhesion, and migration. Membranes feature cholesterol-rich caveolae with caveolin proteins, playing roles in epithelial-mesenchymal transition and cancer progression. Despite elevated cholesterol levels in tumors, its precise function and the effects of its depletion in oral squamous cell carcinoma remain unclear.

Simultaneous presentation of juvenile ossifying fibroma in the maxilla and mandible: a case report.

Introduction: Juvenile ossifying fibroma (JOF) is a controversial and uncommon lesion that has been distinguished from the larger group of ossifying fibromas because of distinct clinical features and some morphological peculiarities. Furthermore, JOF shows an aggressive biological behavior that has led researchers to consider it a benign neoplasm, resulting in its differential diagnosis with important benign and malignant bone neoplasms.

Presentation Of Case: This study describes a case of synchronous presentation of JOF in the mandible and maxilla of a young patient.
