PPARγ (peroxisome-proliferator-activated receptor γ) is a master transcription factor involved in adipogenesis through regulating adipocyte-specific gene expression. Recently, lipin1 was found to act as a key factor for adipocyte maturation and maintenance by modulating the C/EBPα (CCAAT/enhancer-binding protein α) and PPARγ network; however, the precise(More)
Krüppel-like factor 4 (KLF4) is a transcription factor that plays an important role in cell differentiation, proliferation, and survival, especially in the context of cancers. This study revealed that KLF4 activates glycolytic metabolism in breast cancer cells by up-regulating the platelet isoform of phosphofructokinase (PFKP). KLF4 activated the(More)
Markers of proliferation are considered to have prognostic importance in breast cancer (BC). The Ki-67 index has been reported as a prognostic factor, but standardized cutoff values and counting methods are not yet established. We assayed the Ki-67 labeling index (LI) of 589 consecutive operable BC patients who underwent surgical resection. Ki-67(More)
PURPOSE To analyze the cutoff severity of early lesions according to recovery rate after fluoride treatment. METHODS 100 specimens were demineralized over 3 to 40 days. Specimens were immersed in 2% sodium fluoride solution for 4 minutes, and then in artificial saliva for the rest of the total 24 hours. After 10-time repetition of this cycle, the deltaF(More)
BACKGROUND It is well-known that persistent cervical infections with high-risk human papillomavirus (HPV) are related to the development of high-grade cervical intraepithelial neoplasia and invasive cervical cancer and that infection with HPV 16 and HPV 18 accounts for approximately 70% of all cases of invasive cervical cancer. METHODS We performed 3 HPV(More)
OBJECTIVES Detection of approximal caries lesions can be difficult due to their anatomical position. This study aimed to assess the ability of the quantitative light-induced fluorescence-digital (QLF-D) in detecting approximal caries, and to compare the performance with those of the International Caries Detection and Assessment System II (ICDAS II) and(More)
As an effort to develop improved ligand exchange chiral stationary phases (CSPs) for the resolution of chiral drugs, the residual silanol groups on the silica surface of a CSP based on sodium N-[(S)-1-hydroxymethyl-3-methylbutyl]-N-undecylaminoacetate, a (S)-leucinol derivative, were protected with n-octyl groups. The residual silanol group-protected CSP(More)
Phosphoglucomutase (PGM)1 catalyzes the reversible conversion reaction between glucose-1-phosphate (G-1-P) and glucose-6-phosphate (G-6-P). Although both G-1-P and G-6-P are important intermediates for glucose and glycogen metabolism, the biological roles and regulatory mechanisms of PGM1 are largely unknown. In this study we found that T553 is obligatory(More)
PURPOSE To determine the optimal electric current intensity of fluoride iontophoresis (FI) for remineralisation of early caries lesions in vitro. MATERIALS AND METHODS Sixty specimens were made from bovine incisors and immersed in a demineralising gel for 96 h. Specimens were divided into control (conventional fluoride application) and experimental (FI)(More)
