The high frequencies of recurrence and distant metastasis of adenoid cystic carcinoma (AdCC) emphasize the need to better understand the biological factors associated with these outcomes. To analyze the mechanisms of AdCC metastasis, we established the green fluorescence protein (GFP)-transfected subline ACCS-GFP from the AdCC parental cell line and the(More)
Silene latifolia is a model dioecious plant with morphologically distinguishable XY sex chromosomes. The end of the Xq arm is quite different from that of the Yp arm, although both are located at opposite ends of their respective chromosomes relative to a pseudo-autosomal region. The Xq arm does not seem to originate from the same autosome as the Yp arm.(More)
In this study, we analyzed the effect of the metastasis suppressor CD82/KAI-1, a member of the tetraspanin superfamily, on intercellular adhesion on cancer cells. The newly established invasion assay and the cell aggregation assay revealed that CD82 strengthens E-cadherin-mediated intercellular adhesion. Interestingly, ectopic expression of CD82 stabilized(More)
The prognosis of patients with oral squamous cell carcinoma (SCC) is influenced by the presence of lymph node metastasis. In this study, we analyzed the relationship between lymphangiogenesis and the expression of VEGF-C and VEGF-D in association with lymph node metastasis in oral SCC. Oral SCC biopsy specimens (160 cases) were examined for lymphatic vessel(More)
The prognosis of patients with oral squamous cell carcinoma (SCC) is influenced by the presence of lymph node metastasis. Epithelial-mesenchymal transition (EMT), a process that involves events that convert adherent epithelial cells into individual migratory cells that can invade the extracellular matrix, is critical for(More)
Sexual dimorphism is controlled by genes on the Y chromosome in the dioecious plant Silene latifolia. K034 is the first mutant with female flowers and asexual flowers in one individual. Its stamens are suppressed completely, and its gynoecium exhibits two suppression patterns. One gynoecium resembles a thin rod, as in wild-type males (asexual flower); the(More)
The soil bacterium Bacillus subtilis forms dormant, robust spores as a tactic to ensure survival under conditions of starvation. However, the sporulating culture includes sporulating and non-sporulating cells, because a portion of the cell population initiates sporulation in wild-type strain. We anticipated that the population effect must be considered(More)
The high frequencies of recurrence and distant metastasis of adenoid cystic carcinoma (AdCC) are significant obstacles for the long-term cure of patients with AdCC and emphasize the need for better understanding of the biological factors associated with these outcomes. To identify proteins that mediate AdCC metastasis, we established three AdCC cell lines(More)
Adenoid cystic carcinoma (AdCC) is highly metastatic and resistant to chemotherapy and radiotherapy. Recently, we reported that the T-box transcription factor Brachyury is a potential regulator of cancer stem cells (CSCs). Specifically, growth of CSCs was found to be controlled by Brachyury knockdown in AdCC. Since CSCs are resistant to chemotherapy and(More)
Sex determination in Silene latifolia uses the XX/XY system. The recent evolution of dioecy in S. latifolia provides a unique opportunity to study the early stages of Y chromosome evolution. However, the current Y chromosome map still contains many large gaps with no available markers. In this study, a sequence tagged site (STS) marker, MS2, was isolated(More)
