14-3-3 s, a target gene of the p53 tumour suppressor protein, has been shown to regulate the cell cycle at the G2/M checkpoint. Recent studies have demonstrated that 14-3-3 s is downregulated by hypermethylation of the CpG island in several types of cancer. In this study, we investigated the expression and methylation status of 14-3-3 s in human salivary(More)
We examined the expression of cytokeratin 20 (CK20) mRNA in the peripheral blood of oral squamous cell carcinoma (SCC) patients by reverse transcriptase polymerase chain reaction (RT-PCR). Eleven out of 12 oral SCC patients showed positive RT-PCR results. However, there is no clear relationship between the haematogenous CK20 mRNA and the metastasis. After(More)
We studied the effect of bafilomycin A1 (Baf-A1), a novel and highly specific inhibitor for vacuolar-type proton (V-H+) pump, on the growth of Japanese Encephalitis virus (JEV) in Vero cells. Viral fluorescence microscopic study showed that Baf-A1 induced the complete disappearance of acidified compartments such as endosomes and lysosomes in Vero cells by(More)
We undertook the present study to clarify the molecular mechanism of the effect of a new anti-cancer drug, vesnarinone, on a human salivary gland cancer cell line, TYS. We isolated TSC-22cDNA as avesnarinone-inducible gene from a cDNA library constructed from vesnarinone-treated TYS cells. TSC-22 was originally reported as a transforming growth factor(More)
Retinoids inhibit the proliferation of several types of tumour cells, and are used for patients with several malignant tumours. In this study, we examined the effect of retinoic acids (RAs) on the invasive potentials of the oral squamous cell carcinoma (SCC) cells, BHY and HNt. BHY cells expressed all of retinoid nuclear receptors (RARalpha, beta, gamma,(More)
In this study, we generated transgenic (Tg) mice, which overexpressed transforming growth factor (TGF)-β stimulated clone-22 (TSC-22), and investigate the functional role of TSC-22 on their development and pathogenesis. We obtained 13 Tg-founders (two mice from C57BL6/J and 11 mice from BDF1). Three of 13 Tg-founders were sterile, and the remaining(More)
The patient was a 5-day-old boy born at 37 weeks and 4 days. At birth, an amniotic band encircling and constricting his left middle finger was noted, in addition to multiple anomalies including a right-side cleft lip and palate, a club foot, and syndactyly on the left hand. We performed cheiloplasty at 5 months, and palatoplasty at 18 months.
