BACKGROUND Human periodontal ligament (PDL) cells underwent apoptosis after mechanical stretch loading. However, the exact signalling pathway remains unknown. This study aimed to elucidate how the apoptotic caspases functioned in the cyclic stretch-induced apoptosis in human PDL cells. MATERIALS AND METHODS In the present study, 20% cyclic stretch was selected to load the cells for 6 or 24 h....

Introduction: Repetitive cortical spreading depression (CSD) can lead to cell death in immature brain tissue. Caspases are involved in neuronal cell death in several CSD-related neurological disorders. Yet, whether repetitive CSD itself can induce caspase activation in adult or juvenile tissue remains unknown. Inducing repetitive CSD in somatosensory cortices of juvenile and adult rats in vivo,...

Sedum middendorffianum Maxim (SMM) is a Korean endemic plant belonging to the Crassulaceae family. This study aimed investigate antitumor effects of SMM extract on human ovarian cancer cells. Among five plants grown in Korea, showed most potent cytotoxicity cells and had little effect normal surface epithelial Furthermore, we revealed that dose-dependently induced apoptosis A2780 SKOV3 The mark...

Apoptosis plays a dual role in cancer development and malignancy. The role of apoptosis-related caspases in cancer remains controversial, particularly in oral tongue squamous cell carcinoma (OTSCC). In this study, we examined the protein levels of cleaved caspase-3, caspase-3, caspase-8, and caspase-9 on tissue microarrays consisting of samples from 246 OTSCC patients by immunohistochemistry. W...
