One of the theories regarding oral carcinogenesis is that the tumor growth is initiated from cancer stem cells (CSCs) that self-renew and give rise to differentiated tumor cells, like stem cells do in normal tissues. The most common methods of CSC identification are based on CSC marker expression in carcinogenesis. This study examined the expression of(More)
BACKGROUND Photodynamic therapy (PDT) is an anticancer treatment that generates excessive reactive oxygen species after photosensitizer treatments following specific wavelength irradiation. In another reports, PDT was regulated with autophagic cell death and apoptotic cell death. However, the mechanism of PDT resistance in PDT-stimulated cell death is(More)
OBJECTIVES Abnormal cellular immune response has been considered to be responsible for oral lesions in recurrent aphthous stomatitis. Zinc has been known to be an essential nutrient metal that is necessary for a broad range of biological activities including antioxidant, immune mediator, and anti-inflammatory drugs in oral mucosal disease. The objective of(More)
