BACKGROUND Loss of the interproximal dental papilla may cause functional and, especially in the maxillary anterior region, phonetic and severe esthetic problems. The purpose of this study was to investigate whether the distance from the contact point to the bone crest on standardized periapical radiographs of the maxillary anterior teeth could be correlated(More)
The anti-tumor effects of 11-dehydrosinulariolide, an active ingredient isolated from soft coral Sinularia leptoclados, on CAL-27 cells were investigated in this study. In the MTT assay for cell proliferation, increasing concentrations of 11-dehydrosinulariolide decreased CAL-27 cell viability. When a concentration of 1.5 μg/mL of 11-dehydrosinulariolide(More)
Sinulariolide, an isolated compound from the soft coral Sinularia flexibilis, possesses the anti-proliferative, anti-migratory and apoptosis-inducing activities against the TSGH bladder carcinoma cell. The anti-tumor effects of sinulariolide were determined by 3-(4,5-cimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, cell migration assay and flow(More)
Exopolysaccharides (EPSs) are a metabolite of probiotics which have gained wide interest recently, but little is known about their function. EPS was isolated from Bifidobacterium longum BCRC 14634 and sterilized by 0.22 μm filter. The proliferation of J77A.1 macrophages and their secretion of the anti-inflammatory cytokine interleukin-10 (IL-10) was(More)
Heavy metals are toxic to most living organisms and cause health problems by contaminating agricultural products. In plants, phytochelatin synthase (PCS, EC 2.3.2.15) uses glutathione (GSH) as its substrate to catalyze the synthesis of heavy metal-binding peptides, known as phytochelatins (PC). PCS has been described as a constitutive enzyme that may be(More)
Gallic acid is one of the major flavonoids found in plants. It acts as an antioxidant, and seems to have anti-inflammatory, anti-viral, and anti-cancer properties. In this study, we investigated the effects of gallic acid on melanogenesis, including the activation of melanogenesis signaling pathways. Gallic acid significantly inhibited both melanin(More)
In this study the isolated compound 11-dehydrosinulariolide from soft coral Sinularia leptoclados possessed anti-proliferative, anti-migratory and apoptosis-inducing activities against A2058 melanoma cells. Anti-tumor effects of 11-dehydrosinulariolide were determined by MTT assay, cell migration assay and flow cytometry. Growth and migration of melanoma(More)
Lymph node metastasis is the hallmark of malignant neoplasms in patients of oral cancer, accounting for the poor diagnosis and reduced 5-year survival rate. Here we sought to identify cell motility-associated proteins of oral cancer by proteomic approach. We compared the proteomes of two oral cancer cells, CAL-27 and SAS, with the highest and the lowest(More)
OBJECTIVES/HYPOTHESIS The mechanisms of cholesteatoma proliferation and growth remain unclear. The objective of this study is to discover the potential mechanisms of the proliferation and growth of cholesteatoma by direct experimental assessments on cholesteatoma tissues from patients. STUDY DESIGN Retrospective study by the comparisons between(More)
Betel quid (BQ) is a widely accepted etiological factor for oral squamous cell carcinoma (OSCC) in Southeast Asia, but how BQ chewing leads to oral carcinogenesis remains to be elucidated. We have previously demonstrated that the activation of Src family kinases (SFKs) is critical for BQ-induced oral cancer cell motility. Here we investigate whether this(More)
