Recent studies suggest that tumor-associated macrophages (TAMs) promote tumor growth and metastasis. Our previous report demonstrated that Axl signaling promotes carcinogenesis and progression of oral squamous cell carcinoma (OSCC). This study aims to test the potential involvement of growth arrest-specific gene 6 (Gas6)/Axl signaling in the protumoral(More)
This case report describes the continued root formation following replantation and conventional root canal therapy of a traumatically avulsed open-apex tooth with suppurative apical periodontitis. A 7-year-old male patient had an avulsed upper left central incisor (tooth 21) replanted approximately 50 min after traumatic avulsion. A root canal procedure was(More)

OBJECTIVE This study aims to test the potential involvement of Axl signaling in the protumoral effect of tumor-associated macrophages (TAMs) in mucoepidermoid carcinoma (MEC). MATERIALS AND METHODS We carried out cocultured experiments by incubation of MEC cells (UTMUC-1) and macrophages (THP-1) and examined Axl activation status. The expression of MMPs(More)
