Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine that signals through the interaction of type I (TbetaRI) and type II (TbetaRII) receptors to activate distinct intracellular pathways. TAK1 is a serine/threonine kinase that is rapidly activated by TGF-beta1. However, the molecular mechanism of TAK1 activation is incompletely(More)
PURPOSE To compare changes in corneal nerve fibers and keratocyte density by confocal microscopy after laser-assisted in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK). DESIGN Prospective, nonrandomized comparative clinical trial. METHODS Fifty-six eyes of 28 patients who underwent LASIK and 52 eyes of 26 patients who underwent(More)
Recombination promotes retrovirus evolution. It involves transferring a growing DNA primer from one genomic RNA template in the virus to the other. Strand transfer results in vitro suggested that pausing of the reverse transcriptase during synthesis allows enhanced RNase H cleavage of the initial, or donor, RNA template that facilitates primer interaction(More)
Transforming growth factor-beta1 (TGF-beta1) plays essential roles in a wide array of cellular processes, such as in development and the pathogenesis of tissue fibrosis, including that associated with progressive kidney diseases. Tight regulation of its signaling pathways is critical, and proteins that associate with the TGF-beta receptors may exert(More)

The mean platelet volume (MPV), a readily available indicator of platelet activation and function, is a useful predictive and prognostic biomarker of cardiovascular and cerebrovascular disease (CVD). It is associated with a variety of prothrombotic and proinflammatory diseases. Larger platelets are more likely to aggregate and release greater quantities of(More)
BACKGROUND Peritoneal dialysis (PD) is characterized by gain in fat mass. Visceral fat mass is associated with metabolic syndrome and atherosclerosis rather than subcutaneous fat mass. In addition, the change in visceral fat mass is a more reliable predictor of survival in PD patients. In this study, we prospectively examined serial changes in fat(More)
IMPORTANCE OF THE FIELD Chronic kidney disease (CKD) has become a worldwide public health problem. Renal transplantation is the treatment of choice for end-stage renal disease, but is limited by a small number of organ donors and the immune barrier. To overcome these problems, new therapeutic strategies for tissue repair have recently emerged. AREAS(More)
BACKGROUND Cardiovascular disease is the main cause of mortality in dialysis patients. Carotid intima-media thickness (CIMT) is used as a surrogate marker of early atherosclerosis. Atherosclerosis can cause vascular access failure. The purpose of this study was to define the clinical features of atherosclerosis in hemodialysis patients based on CIMT and to(More)
Kidney injury molecule-1 (KIM-1) is a sensitive biomarker for proximal tubular injury. Recently, a few studies have shown that urinary KIM-1 has clinical implications in IgA nephropathy (IgAN). We performed this study to determine whether tissue KIM-1 has clinical implications for predicting long-term outcome and whether urinary KIM-1 is correlated with(More)
Autophagy can lead to cell death in response to stress, but it can also act as a protective mechanism for cell survival. We show that TGF-β1 induces autophagy and protects glomerular mesangial cells from undergoing apoptosis during serum deprivation. Serum withdrawal rapidly induced autophagy within 1 h in mouse mesangial cells (MMC) as determined by(More)
