HNF4α is required for Tkfc promoter activation by ChREBP.

Triokinase/FMN cyclase (Tkfc) is involved in fructose metabolism and is responsible for the phosphorylation of glyceraldehyde to glyceraldehyde-3-phosphate. In this study, we showed that refeeding induced hepatic expression of Tkfc in mice. Luciferase reporter gene assays using the Tkfc promoter revealed the existence of 2 hepatocyte nuclear factor 4α (HNF4α)-responsive elements (HNF4RE1 and HNF4RE2) and 1 carbohydrate-responsive element-binding protein (ChREBP)-responsive element (ChoRE1).

Chrysin 7-O-β-d-glucopyranoside increases hepatic low-density lipoprotein receptor expression through AMP-activated protein kinase activation.

Elevated plasma low-density lipoprotein (LDL) cholesterol level is a risk factor for developing atherosclerosis. Increased LDL receptor (LDLR) expression is expected to reduce the risk of atherosclerotic disease since hepatic LDLR is essential for clearing plasma LDL cholesterol. Here, we screened human LDLR promoter effectors and observed that extracts from peduncles of sweet cherry (Prunus avium) 'Sato-Nishiki' induce LDLR gene promoter activity.

Sulforaphane suppresses the activity of sterol regulatory element-binding proteins (SREBPs) by promoting SREBP precursor degradation.

Sterol regulatory element-binding proteins (SREBPs) are transcription factors that regulate various genes involved in cholesterol and fatty acid synthesis. In this study, we describe that naturally occurring isothiocyanate sulforaphane (SFaN) impairs fatty acid synthase promoter activity and reduces SREBP target gene (e.g.

MIG12 is involved in the LXR activation-mediated induction of the polymerization of mammalian acetyl-CoA carboxylase.

Liver X receptors (LXR) α and β are a family of nuclear receptors that regulate lipogenesis by controlling the expression of the genes involved in the synthesis of fatty acids. MID1IP1, which encodes MIG12, is a target gene of LXR. MIG12 induces fatty acid synthesis by stimulating the polymerization-mediated activation of acetyl-CoA carboxylase (ACC).

Characterization of a novel compound that promotes myogenesis via Akt and transcriptional co-activator with PDZ-binding motif (TAZ) in mouse C2C12 cells.

Transcriptional co-activator with PDZ-binding motif (TAZ) plays versatile roles in the regulation of cell proliferation and differentiation. TAZ activity changes in response to the cellular environment such as mechanic and nutritional stimuli, osmolarity, and hypoxia. To understand the physiological roles of TAZ, chemical compounds that activate TAZ in cells are useful as experimental reagents.

Application of Split-GFP Reassembly Assay to Study Myogenesis and Myofusion In Vitro.

Green fluorescent protein (GFP) is composed of 11 β-strands, and loses GFP signals, when divided into the N-terminal ten β-strands (GFP1-10) and the C-terminal last β-strand (GFP11). However, when GFP1-10 and GFP11 encounter, they reassemble into the fluorescent GFP. We expressed GFP1-10 and blasticidin resistance gene product-fused GFP11 (BSR-GFP11) in C2C12 cells.

Loop diuretics affect skeletal myoblast differentiation and exercise-induced muscle hypertrophy.

Muscle wasting or sarcopenia contributes to morbidity and mortality in patients with cancer, renal failure, or heart failure, and in elderly individuals. Na-K-2Cl cotransporter 1 (NKCC1) is highly expressed in mammalian skeletal muscle, where it contributes to the generation of membrane ion currents and potential. However, the physiologic function of NKCC1 in myogenesis is unclear.

A new cell-based assay to evaluate myogenesis in mouse myoblast C2C12 cells.

The development of the efficient screening system of detecting compounds that promote myogenesis and prevent muscle atrophy is important. Mouse C2C12 cells are widely used to evaluate myogenesis but the procedures of the assay are not simple and the quantification is not easy. We established C2C12 cells expressing the N-terminal green fluorescence protein (GFP) and the C-terminal GFP (GFP1-10 and GFP11 cells).

MAGI2/S-SCAM outside brain.

Membrane-associated guanylate kinase with an inverted arrangement of protein-protein interaction domains (MAGI)2 (also called synaptic scaffolding molecule (S-SCAM), atrophin-1-interacting protein 1, activin receptor-interacting protein 1) is a scaffold protein that binds a wide variety of receptors, cell adhesion molecules and signalling molecules. It also interacts with other scaffold proteins and adaptors, and forms a protein network that supports cell junctions. As it is highly expressed in brain, the study on its roles in synaptic organization initially preceded.

The mammalian Hippo pathway: regulation and function of YAP1 and TAZ.

The Hippo pathway was originally identified as the signaling that controls organ size in Drosophila, with the core architecture conserved in mammals. In the mammalian Hippo pathway, mammalian Ste20-like kinases (MST1/2) and large tumor suppressor kinases (LATS1/2) regulate transcriptional co-activators, Yes-associated protein (YAP1) and Transcriptional co-activator with a PDZ-binding motif (TAZ). The Hippo pathway was initially thought to be quite straightforward; however, the identification of additional components has revealed its inherent complexity.

Factors associated with perceived feasibility and willingness of non-psychiatric doctors in Japan to treat depressed patients.

Objectives: We previously reported that many non-psychiatric doctors in Japan believe that treating depression was not part of their duties. Educational interventions must address motivation of physicians to play a role in depression care. In this study, we explored factors associated with perceived feasibility and willingness of non-psychiatric doctors in Japan to treat depression.

Attitudes toward depression among Japanese non-psychiatric medical doctors: a cross-sectional study.

Background: Under-recognition of depression is common in many countries. Education of medical staff, focusing on their attitudes towards depression, may be necessary to change their behavior and enhance recognition of depression. Several studies have previously reported on attitudes toward depression among general physicians.

Misalignments of rest-activity rhythms in inpatients with schizophrenia.

Aims: Rest-activity rhythms of human beings generally synchronize to a 24-h time cue. Very few detailed research studies have examined rest-activity rhythms in patients with schizophrenia. The present study aimed to explore (i) rest-activity rhythms in patients with schizophrenia, and (ii) factors relevant to their rhythm characteristics.

Symptom dimensions and needs of care among patients with schizophrenia in hospital and the community.

The purpose of the present paper was to examine the psychiatric symptom dimensions related to needs of care among patients with schizophrenia in hospital and in the community. Subjects were 217 patients with F2 ICD-10 diagnoses. Hospital patients included 102 inpatients (47.
