The ability to store fat in the form of cytoplasmic triglyceride droplets is conserved from Saccharomyces cerevisiae to humans. Although much is known regarding the composition and catabolism of lipid droplets, the molecular components necessary for the biogenesis of lipid droplets have remained obscure. Here we report the characterization of a conserved(More)
Mobile group II introns are site-specific retroelements that use a novel mobility mechanism in which the excised intron RNA inserts directly into a DNA target site and is then reverse transcribed by the associated intron-encoded protein. Because the DNA target site is recognized primarily by base-pairing of the intron RNA with only a small number of(More)
Adipocyte complement-related protein of 30 kDa (Acrp30, adiponectin, or AdipoQ) is a fat-derived secreted protein that circulates in plasma. Adipose tissue expression of Acrp30 is lower in insulin-resistant states and it is implicated in the regulation of in vivo insulin sensitivity. Here we have characterized the ability of PPARgamma agonists to modulate(More)
OBJECTIVE This article describes the initial development of a novel approach for training hearing-impaired listeners to improve their ability to understand speech in the presence of background noise and to also improve their ability to localize sounds. DESIGN Most people with hearing loss, even those well fit with hearing devices, still experience(More)
PURPOSE The Janus-activated kinase/signal transducers and activators of transcription (STAT) pathway of IFN signaling is important to immunoregulation and tumor progression. STAT1 plays a prominent role in the effector immune response, whereas STAT3 is implicated in tumor progression and down-regulation of the response to type I IFNs. The goal of this study(More)
Osteosarcoma (OS) is the most common nonhematologic bone malignancy in children and adolescents. Despite the advances of adjuvant chemotherapy and significant improvement of survival, the prognosis remains generally poor. As such, the search for more effective anti-OS agents is urgent. The phosphatidylinositol 3-kinase (PI3K)/Akt pathway is thought to be(More)
BACKGROUND/AIMS The examination of HCV virological clearance through several randomized clinical trials of telaprevir in genotype 1 chronic hepatitis C. METHODOLOGY We analyzed the effect of telaprevir on the end of treatment virological response and the sustained response, and investigated its harmful effect using meta-analysis of 5 randomized controlled(More)
Signal transducer and activator of transcription (STAT3) plays a pivotal role in tumor progression. Atypical nevi are nonobligate risk markers of melanoma, affording investigators a target for evaluation of progression biomarkers in vivo. pSTAT1tyr701 (pSTAT1) and pSTAT3tyr705 (pSTAT3) oppose one another in biological function. Therefore, an analysis of(More)
Dehydroepiandrosterone (DHEA) may be a promising agent for postmenopausal osteoporosis (PMO), but its mechanism to modulate osteoblasts (OBs) is yet to be explained. To elucidate the effects of DHEA treatment on the ovariectomized (OVX) mice and its mechanisms, we evaluated the morphology of mice bone tissue and expression of proliferating cell nuclear(More)
The homeobox, msh-like 1 (MSX1) protein is essential for cell proliferation and differentiation. Tooth germ development of Msx1 knockout mouse is arrested at the bud stage, impeding an understanding of its role beyond this stage of tooth development. The aims of this study were to investigate the potential role of MSX1 in the regulation of proliferation and(More)
