BACKGROUND: Data on treatment results of lipid-lowering therapy (LLT) in familial hypercholesterolemia (FH) are limited, particularly in Asian patients. HYPOTHESIS: We sought to evaluate the target achievement rate and associated variables in Korean patients with FH after maximal statin-based LLT. METHODS: We enrolled 146 patients with heterozygous FH, and 90 patients were finally analyzed. Patients were initially prescribed rosuvastatin 10 mg or atorvastatin 20 mg, and the regimen was adjusted to achieve the low-density lipoprotein cholesterol (LDL-C) target of 100 mg/dL...

BACKGROUND: Cytosine methylation is a stable epigenetic modification of DNA that plays an important role in both normal physiology and disease. Most diseases exhibit some degree of sexual dimorphism, but the extent to which epigenetic states are influenced by sex is understudied and poorly understood. To address this deficit we studied DNA methylation patterns across multiple reduced representation bisulphite sequencing datasets (from liver, heart, brain, muscle and spleen) derived from isogenic male and female mice...

Glycogen synthase kinases 3 (GSK3) α and β are expressed in the nervous system, and disruption of GSK3 signaling has been implicated in a wide range of neurodevelopmental and psychiatric disorders. Although several studies have established a role of GSK3 signaling in the nervous system, much less is known about isoform-specific functions. Here, we have examined the role of GSK3α and GSK3β in the developing neocortex by performing in utero electroporation with specific small interfering RNAs targeting each isoform...

Peroxisome proliferator-activated receptor (PPAR) δ plays a pivotal role in metabolic homeostasis through its effect on insulin signaling. Although diverse genomic actions of PPARδ are postulated, the specific molecular mechanisms whereby PPARδ controls insulin signaling have not been fully elucidated. We demonstrate here that short-term activation of PPARδ results in formation of a stable complex with nuclear T cell protein tyrosine phosphatase 45 (TCPTP45) isoform. This interaction of PPARδ with TCPTP45 blocked translocation of TCPTP45 into the cytoplasm, thereby preventing its interaction with the insulin receptor, which inhibits insulin signaling...

HuR is an RNA-binding protein of the embryonic lethal abnormal vision (ELAV) family, which binds to the AU-rich element (ARE) in the 3'-untranslated region (UTR) of certain mRNAs and is involved in the nucleo-cytoplasmic export and stabilization of ARE-mRNAs. The cytoplasmic relocalization of ARE-mRNAs with several proteins such as HuR and pp32 increases in cells transformed by the adenovirus oncogene product E4orf6. Additionally, these ARE-mRNAs were stabilized and acquired the potential to transform cells...

Social behaviors are crucial to all mammals. Although the prelimbic cortex (PL, part of medial prefrontal cortex) has been implicated in social behavior, it is not clear which neurons are relevant or how they contribute. We found that PL contains anatomically and molecularly distinct subpopulations that target three downstream regions that have been implicated in social behavior: the nucleus accumbens (NAc), amygdala, and ventral tegmental area. Activation of NAc-projecting PL neurons (PL-NAc), but not the other subpopulations, decreased the preference for a social target...

Under current guidelines hepatitis C virus (HCV)-positive livers are not transplanted into HCV-negative recipients because of adverse post-transplant outcomes associated with allograft HCV infection. However, HCV can now be cured post liver transplant (LT) using direct-acting antivirals (DAAs) with >90% success; therefore, HCV-negative patients on the liver transplant (LT) waiting list may benefit from accepting HCV-positive organs with preemptive treatment. Our objective was to evaluate if and in which HCV-negative patients the potential benefit of accepting an HCV-positive (i...

Granulocyte-macrophage colony-stimulating factor (GM-CSF) produced by T helper 17 (Th17) cells plays an essential role in autoimmune diseases. Transcriptional regulation of Th17 cell differentiation has been extensively studied, but post-transcriptional regulation of Th17 cell differentiation has remained less well characterized. The RNA-binding protein HuR functions to promote the stability of target mRNAs via binding the AU-rich elements of the 3' untranslated region (3'UTR) of numerous pro-inflammatory cytokines including IL-4, IL-13, IL-17 and TNF-α...

This paper describes the fabrication and characterization of a reconfigurable Yagi-Uda antenna based on a silicon reflector with a solid-state plasma. The silicon reflector, composed of serially connected p-i-n diodes, forms a highly dense solid-state plasma by injecting electrons and holes into the intrinsic region. When this plasma silicon reflector is turned on, the front-realized gain of the antenna increases by more than 2 dBi beyond 5.3 GHz. To achieve the large gain increment, the structure of the antenna is carefully designed with the aid of semiconductor device simulation and antenna simulation...

cAMP-responsive element-binding protein (CREB)-regulated transcriptional coactivator 3 (CRTC3) is well known to be related to obesity in humans and mice. However, the effects of CRTC3 have not been studied in pigs. Here, we characterized the structure of the porcine CRTC3 gene and identified single nucleotide polymorphisms (SNPs) in its coding region. Moreover, mRNA expression profiles of CRTC3 in muscle and fat tissues were examined. Of the 40 identified SNPs, the p.V515F mutation, located on exon 16, was genotyped in 368 Yorkshire pigs...

Human epidermal growth factor receptor 2 (HER2) mutation in non-small cell lung cancer (NSCLC) is an oncogenic driver that possibly becomes a druggable target to HER2-targeted therapy. The benefit of HER2-targeted therapy is much less defined especially in eastern populations. We provide evidence of clinical benefit of afatinib in a 50-year-old Asian woman with HER2-mutant NSCLC who previously failed cytotoxic chemotherapy and gefitinib treatment. Next-generation sequencing of the tumor tissue revealed a HER2 exon 20 mutation (c...

Migration and invasion of cancer cells into surrounding tissue is a key stage of cancer metastasis. Here, we show that peroxisome proliferator-activated receptor (PPAR) δ regulates migration and invasion of human breast cancer cells via thrombospondin-1 (TSP-1) and its degrading protease, a disintegrin and metalloprotease domains with thrombospondin motifs 1 (ADAMTS1). Activation of PPARδ by GW501516, a specific ligand for PPARδ, led to marked inhibition in the cell migration and TSP-1 expression of breast cancer...
