Abstract
In this study, the effects of 3,5,7,3',4'-pentamethoxyflavone (KP1), a major bioactive ingredient isolated from the Kaempferia parviflora rhizomes, on a neurite outgrowth in Neuro2a cells and its mechanism have been investigated. KP1 increased concentration-dependently the percentage of neurite-bearing cells. KP1 showed a remarkable capability to elicit neurite outgrowth in Neuro2a cells, as evidenced by morphological alterations and immunostaining using anti-class III β-tubulin and anti-NeuN antibodies. KP1 also displayed a higher neurogenic activity than retinoic acid (RA), a promoter of neurite outgrowth in Neuro2a cells. KP1 treatment caused significant elevation in phosphorylation of extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (p38 MAPK) and glycogen synthase kinase-3β (GSK-3β). However, KP1-triggered neurite outgrowth was markedly inhibited by treatment with the ERK inhibitor U0126, whereas p38 MAPK inhibitor SB203580 and GSK-3β inhibitor SB216763 did not influence KP1-induced neurite outgrowth. These results demonstrate that KP1 elicits neurite outgrowth and triggers cell differentiation of Neuro2a cells through ERK signal pathway.

Abstract
In this study we observed that human GD1c/GT1a/GQ1b synthase (hST8Sia V) is particularly expressed in human glioblastoma cells. To address the mechanism regulating human glioblastoma-specific gene expression of the hST8Sia V, after the transcription start site (TSS) was identified by the 5'-rapid amplification of cDNA end with total RNA from human glioblastoma U87MG cells, the 5'-flanking region (2.5 kb) of the hST8Sia V gene was isolated and its promoter activity was examined. By luciferase reporter assay, this 5'-flanking region revealed strong promoter activity in only U-87MG cells, but not in other tissue-derived cancer cells. 5'-deletion mutant analysis showed that the region from -1140 to -494 is crucial for transcription of the hST8Sia V gene in U87MG cells. This region contains the activator protein-1 (AP-1) binding site, the main target of the c-Jun N-terminal kinase (JNK) downstream. The AP-1 binding site at -1043/-1037 was proved to be indispensable for the hST8Sia V gene-specific expression in U87MG cells by site-directed mutagenesis. Moreover, the transcriptional activation of hST8Sia V gene in U87MG cells was strongly inhibited by a specific JNK inhibitor, SP600125. These results suggest that the hST8Sia V gene-specific expression in U87MG cells is controlled by JNK/AP-1 signaling pathway.

Abstract
In this study, we have firstly elucidated that serum starvation augmented the levels of human GD3 synthase (hST8Sia I) gene and ganglioside GD3 expression as well as bone morphogenic protein-2 and osteocalcin expression during MG-63 cell differentiation using RT-PCR, qPCR, Western blot and immunofluorescence microscopy. To evaluate upregulation of hST8Sia I gene during MG-63 cell differentiation by serum starvation, promoter area of the hST8Sia I gene was functionally analyzed. Promoter analysis using luciferase reporter assay system harboring various constructs of the hST8Sia I gene proved that the cis-acting region at -1146/-646, which includes binding sites of the known transcription factors AP-1, CREB, c-Ets-1 and NF-κB, displays the highest level of promoter activity in response to serum starvation in MG-63 cells. The -731/-722 region, which contains the NF-κB binding site, was proved to be essential for expression of the hST8Sia I gene by serum starvation in MG-63 cells by site-directed mutagenesis, NF-κB inhibition, and chromatin immunoprecipitation (ChIP) assay. Knockdown of hST8Sia I using shRNA suggested that expressions of hST8Sia I and GD3 have no apparent effect on differentiation of MG-63 cells. Moreover, the transcriptional activation of hST8Sia I gene by serum starvation was strongly hindered by SB203580, a p38MAPK inhibitor in MG-63 cells. From these results, it has been suggested that transcription activity of hST8Sia I gene by serum starvation in human osteosarcoma MG-63 cells is regulated by p38MAPK/NF-κB signaling pathway.

Abstract
BACKGROUND In this study, we observed that in human colon carcinoma HCT116 cells mRNA level of the human β-galactoside α2,6-sialyltransferase (hST6Gal I) was decreased by curcumin. FACS analysis using the α2,6-sialyl-specific lectin (SNA) also showed a noticeable decrease in binding to SNA by curcumin. OBJECTIVE To investigate the mechanism for curcumin-triggered downregulation of hST6Gal I transcription. METHODS The mRNA levels of nine kinds of hST genes were assessed by RT-PCR after curcumin was treated in HCT116 cells. The level of hST6Gal I product on cell surface was examined by flow cytometry analysis. Luciferase reporter plasmids with 5'-deleted constructs and mutants of the hST6Gal I promoter were transiently transfected into HCT116 cells, and the luciferase activity was measured after treatment with curcumin. RESULTS Curcumin led to significant transcriptional repression of the hST6Gal I promoter. Promoter analysis using deletion mutants proved that the - 303 to - 189 region of the hST6Gal I promoter is required for transcriptional repression in response to curcumin. Among putative binding sites for transcription factors IK2, GATA1, TCF12, TAL1/E2A, SPT, and SL1 in this region, by site-directed mutagenesis analysis the TAL/E2A binding site (nucleotides - 266/- 246) was proved to be crucial for curcumin-triggered downregulation of hST6Gal I transcription in HCT116 cells. The transcription activity of hST6Gal I gene in HCT116 cells was markedly suppressed by compound C, an AMP-activated protein kinase (AMPK) inhibitor. CONCLUSION These indicate that gene expression of hST6Gal I in HCT116 cells is controlled through AMPK/TAL/E2A signal pathway.

Abstract
Abstract
Background
Diabetes mellitus (DM) is highly prevalent among individuals hospitalized with acute myocardial infarction (AMI) and is associated with increased risk for cardiovascular complications and short-term and long-term mortality. However, most existing data are from older patients. Little is known about the incidence of diabetes in individuals who experience AMI at a young age. Whether the presence of DM is associated with worse outcomes in these patients is not clear.
Purpose
To test the hypothesis that the impact of DM on clinical outcomes after AMI can vary by age.
Methods
A total of 12,600 AMI patients from the Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) between November 2011 and December 2015 was classified into young (n=3,590 [28.5%]) and elderly (n=9,010 [71.5%]). Those less than 55 years of age were considered young. We performed comparisons of baseline characteristics, in-hospital treatments, and long-term clinical outcomes between patients with and without diabetes after stratification according to age group.
Results
The prevalence of diabetes mellitus was 26.5% in the young AMI group. In the multivariable-adjusted model of the entire cohort, diabetes mellitus was associated strongly with 3-year all-cause mortality (12.6% vs. 6.8%; adjusted hazard ratio [HR], 1.318; 95% confidence interval [CI], 1.138–1.526; P<0.001). When the entire cohort was subdivided into two age groups, young diabetic patients showed a 107.0% higher mortality rate than those without diabetes (adjusted HR, 2.070; 95% CI, 1.150–3.724; P=0.015). Meanwhile, elderly diabetic patients had a 25.3% higher risk of mortality than non-diabetic patients (adjusted HR, 1.253; 95% CI, 1.076–1.459; P=0.004). The interaction of diabetes with age was significant (adjusted P for interaction = 0.008).
Conclusion
DM is not uncommon in younger AMI patients, and the relative risk of long-term mortality is significantly higher in young patients than in older counterparts. More aggressive treatments are needed to prevent future cardiovascular events in younger patients after AMI.

Abstract
Human N-acetylgalactosamine-α2,6-sialyltransferase (hST6GalNAc I) is the major enzyme involved in the biosynthesis of sialyl-Tn antigen (sTn), which is known to be expressed in more than 80% of human carcinomas and correlated with poor prognosis in cancer patients. Athough high expression of hST6GalNAc I is associated with augmented proliferation, migration and invasion in various cancer cells, transcriptional mechanism regulating hST6GalNAc I gene expression remains largely unknown. In this study, we found that hST6GalNAc I gene expression was markedly augmented by curcumin in HCT116 human colon carcinoma cells. To understand the molecular mechanism for the upregulation of hST6GalNAc I gene expression by curcumin in HCT116 cells, we first determined the transcriptional start site of hST6GalNAc I gene by 5′-RACE and cloned the proximal hST6GalNAc I 5′-flanking region spanning about 2 kb by PCR. Functional analysis of the hST6GalNAc I 5′ flanking region of hST6GalNAc I by sequential 5′-deletion, transient transfection of reporter gene constructs and luciferase reporter assays showed that -378/-136 region is essential for maximal activation of transcription in response to curcumin in HCT 116 cells. This region includes putative binding sites for transcription factors c-Ets-1, NF-1, GATA-1, ER-α, YY1, and GR-α. ChIP analysis and site-directed mutagenesis demonstrated that estrogen receptor α (ER-α) binding site (nucleotides -248/-238) in this region is crucial for hST6GalNAc I gene transcription in response to curcumin stimulation in HCT116 cells. The transcription activity of hST6GalNAc I gene induced by curcumin in HCT116 cells was strongly inhibited by PKC inhibitor (Gö6983) and ERK inhibitor (U0126). These results suggest that curcumin-induced hST6GalNAc I gene expression in HCT116 cells is modulated through PKC/ERKs signal pathway.

Abstract
In this study, we found that gene expression of the human β-galactoside α2,6-sialyltransferase (hST6Gal I) was specifically increased during differentiation of human MG-63 osteoblastic cells by serum starvation (SS). In parallel, a distinct increase in binding to SNA, the α2,6-sialyl-specific lectin, was observed in serum-starved cells, as demonstrated by FACS analysis. 5'-Rapid amplification of cDNA ends analysis demonstrated that the increase of hST6Gal I transcript by SS is mediated by P1 promoter. To elucidate transcriptional regulation of hST6Gal I in SS-induced MG-63 cells, we functionally characterized the P1 promoter region of the hST6Gal I gene. The 5'-deletion analysis of P1 promoter region revealed that the 189 bp upstream region of transcription start site is critical for transcriptional activity of hST6Gal I gene in SS-induced MG-63 cells. This region contains the predicted binding sites for several transcription factors, including AREB6, FOXP1, SIX3, HNF1, YY2, and MOK2. The mutagenesis analysis for these sites and chromatin immunoprecipitation assay demonstrated that the YY2 binding site at -98 to -77 was essential for the SS-induced hST6Gal I gene expression during differentiation of MG-63 cells.

Abstract
BACKGROUND Although asymptomatic microscopic hematuria (MH) is a common finding in clinical practice, its long-term outcome remains unknown. AIM This study evaluated the clinical implication of MH in the general population using a large-scale long-term longitudinal cohort database. METHODS This study included 8719 participants from the Korean Genome and Epidemiology Study between 2001 and 2014. MH was defined as ≥5 red blood cells per high-power field in random urinalysis without evidence of pyuria. The primary study outcome measure was incident chronic kidney disease (CKD), defined as estimated glomerular filtration rate <60 ml min-1⋅1.73⋅m-2. RESULTS During a median follow-up of 11.7 years, CKD occurred in 677 (7.8%) subjects. In Cox regression after adjustment for multiple confounders, subjects with MH had a significantly higher risk of incident CKD than those without [hazard ratio (HR) 1.45, 95% confidence interval (CI) 1.12-1.87; P = 0.005]. Isolated MH without proteinuria was also a risk factor of incident CKD (HR 1.37, 95% CI 1.04-1.79; P = 0.023) and the risk was further increased in MH with concomitant proteinuria (HR 5.41, 95% CI 2.54-11.49; P < 0.001). In propensity score matching analysis after excluding subjects with proteinuria, multi-variable stratified Cox regression analysis revealed that subjects with isolated MH had a significantly higher risk of incident CKD than those without (HR 1.83, 95% CI 1.14-2.94; P = 0.012). CONCLUSION The presence of MH is associated with an increased risk of incident CKD in the general population. Therefore, attentive follow-up is warranted in persons with MH for early detection of CKD.

Abstract
[Purpose] This study examined the effect of belly dancing on the urinary
incontinence-related muscles and vaginal pressure in middle-aged women to provide
fundamental data for establishing an effective training program focusing on mitigating and
preventing urinary incontinence. [Subjects and Methods] The subjects included 24
middle-aged women, who have been diagnosed with urinary incontinence. The subjects were
randomly divided into two groups, viz. the experimental group (N=12) and control group
(N=12). The experimental group underwent a belly dancing program focusing on pelvis moves.
[Results] In the experimental group, the urinary incontinence-related muscle strength and
vaginal pressure were increased, while the control group showed no significant change.
[Conclusion] Belly dancing focusing on pelvis moves had a positive effect on the urinary
incontinence-related muscle strength and vaginal pressure, suggesting that a recreational
dance program focusing on pelvic exercise can be used to prevent and relieve the symptoms
of urinary incontinence as a non-surgical treatment.
