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)
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)
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)
An acyclic receptor immobilized mesoporous silica (ARMS) was prepared by sol-gel reaction and its optical sensing ability was studied upon the addition of heavy metal ions in aqueous solution.
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)
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)
The present study was to (1) develop an ergonomic evaluation system for the systematic analysis of flame-proof clothing (2) comprehensively examine the effectiveness of clothing improvement by using the relationship analysis between clothing design components (D) and ergonomic evaluation measures (E) and (3) prove the usefulness of cost-effectiveness(More)
PURPOSE The aim of this study was to evaluate the efficacy of quantitative light-induced fluorescence-digital (QLF-D) compared to a spectrophotometer in monitoring progression of enamel lesions. METHODS To generate artificial caries with various severities of lesion depths, twenty bovine specimens were immersed in demineralizing solution for 40 days.(More)
Mexiletine, an effective class IB antiarrhythmic agent, and its analogs were resolved on three different crown ether-based chiral stationary phases (CSPs), one (CSP 1) of which is based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid and the other two (CSP 2 and CSP 3) are based on (3,3'-diphenyl-1,1'-binaphthyl)-20-crown-6. Mexiletine was resolved with(More)
