Aging Is Associated With Impaired Activation of Protein Homeostasis-Related Pathways After Cardiac Arrest in Mice.
(Journal of the American Heart Association, 2018-09)Background The mechanisms underlying worse outcome at advanced age after cardiac arrest ( CA ) and resuscitation are not well understood. Because protein homeostasis (proteostasis) is essential for cellular and organismal ... -
Association of Different Estimates of Renal Function With Cardiovascular Mortality and Bleeding in Atrial Fibrillation.
(Journal of the American Heart Association, 2020-09)Background We compared different methods of estimated glomerular filtration rate (eGFR) and their association with cardiovascular death and major bleeding in 14 980 patients with atrial fibrillation in the ARISTOTLE (Apixaban ... -
Autophagy enhances NFκB activity in specific tissue macrophages by sequestering A20 to boost antifungal immunity.
(Nat Commun, 2015-01-22)Immune responses must be well restrained in a steady state to avoid excessive inflammation. However, such restraints are quickly removed to exert antimicrobial responses. Here we report a role of autophagy in an early host ... -
Cloning and expression of a human kidney cDNA for an alpha 2-adrenergic receptor subtype.
(Proc Natl Acad Sci U S A, 1988-09)An alpha 2-adrenergic receptor subtype has been cloned from a human kidney cDNA library using the gene for the human platelet alpha 2-adrenergic receptor as a probe. The deduced amino acid sequence resembles the human platelet ... -
Complement C4 inhibits systemic autoimmunity through a mechanism independent of complement receptors CR1 and CR2.
(J Exp Med, 2000-11-06)The complement system enhances antibody responses to T-dependent antigens, but paradoxically, deficiencies in C1 and C4 are strongly linked to autoantibody production in humans. In mice, disruption of the C1qa gene also ... -
Creatinine- versus cystatin C-based renal function assessment in the Northern Manhattan Study.
(PloS one, 2018-01)BACKGROUND:Accurate glomerular filtration rate estimation informs drug dosing and risk stratification. Body composition heterogeneity influences creatinine production and the precision of creatinine-based estimated glomerular ... -
Dynamics of PTH-induced disassembly of Npt2a/NHERF-1 complexes in living OK cells.
(American journal of physiology. Renal physiology, 2011-01)Parathyroid hormone (PTH) inhibits the reabsorption of phosphate in the renal proximal tubule by disrupting the binding of the sodium-dependent phosphate transporter 2A (Npt2a) to the adapter protein sodium-hydrogen exchanger ... -
Effects of Linagliptin on Cardiovascular and Kidney Outcomes in People With Normal and Reduced Kidney Function: Secondary Analysis of the CARMELINA Randomized Trial.
(Diabetes care, 2020-08)<h4>Objective</h4>Type 2 diabetes is a leading cause of kidney failure, but few outcome trials proactively enrolled individuals with chronic kidney disease (CKD). We performed secondary analyses of cardiovascular (CV) and ... -
Evaluating renal lesions using deep-learning based extension of dual-energy FoV in dual-source CT-A retrospective pilot study.
(European journal of radiology, 2021-06)<h4>Purpose</h4>Dual-source (DS) CT, dual-energy (DE) field of view (FoV) is limited to the size of the smaller detector array. The purpose was to establish a deep learning-based approach to DE extrapolation by estimating ... -
Experimental inhibition of porcupine-mediated Wnt O-acylation attenuates kidney fibrosis.
(Kidney Int, 2016-05)Activated Wnt signaling is critical in the pathogenesis of renal fibrosis, a final common pathway for most forms of chronic kidney disease. Therapeutic intervention by inhibition of individual Wnts or downstream Wnt/β-catenin ... -
Fates of HIV-infected Renal Epithelial Cells Following Virus Acquisition from Infected Macrophages
(2020)Although anti-retroviral therapy (ART) is effective at controlling HIV-1 replication, it does not eradicate the virus from viral reservoirs established throughout the body of infected individuals before therapy initiation. ... -
Ferroptotic stress promotes the accumulation of pro-inflammatory proximal tubular cells in maladaptive renal repair.
(eLife, 2021-07-19)Overwhelming lipid peroxidation induces ferroptotic stress and ferroptosis, a non-apoptotic form of regulated cell death that has been implicated in maladaptive renal repair in mice and humans. Using single-cell transcriptomic ... -
G protein beta gamma subunits stimulate phosphorylation of Shc adapter protein.
(Proc Natl Acad Sci U S A, 1995-09-26)The mechanism of mitogen-activated protein (MAP) kinase activation by pertussis toxin-sensitive Gi-coupled receptors is known to involve the beta gamma subunits of heterotrimeric G proteins (G beta gamma), p21ras activation, ... -
Implementation of automated reporting of estimated glomerular filtration rate among Veterans Affairs laboratories: a retrospective study.
(BMC Med Inform Decis Mak, 2012-07-12)BACKGROUND: Automated reporting of estimated glomerular filtration rate (eGFR) is a recent advance in laboratory information technology (IT) that generates a measure of kidney function with chemistry laboratory results to ... -
Increased renal dopamine and acute renal adaptation to a high-phosphate diet.
(American journal of physiology. Renal physiology, 2011-05)The current experiments explore the role of dopamine in facilitating the acute increase in renal phosphate excretion in response to a high-phosphate diet. Compared with a low-phosphate (0.1%) diet for 24 h, mice ... -
Individuals with mutations in XPNPEP3, which encodes a mitochondrial protein, develop a nephronophthisis-like nephropathy.
(J Clin Invest, 2010-03)The autosomal recessive kidney disease nephronophthisis (NPHP) constitutes the most frequent genetic cause of terminal renal failure in the first 3 decades of life. Ten causative genes (NPHP1-NPHP9 and NPHP11), whose products ... -
Inflammasomes in the urinary tract: a disease-based review.
(American journal of physiology. Renal physiology, 2016-10)Inflammasomes are supramolecular structures that sense molecular patterns from pathogenic organisms or damaged cells and trigger an innate immune response, most commonly through production of the proinflammatory cytokines ... -
Lack of evidence for a remote effect of renal ischemia/reperfusion acute kidney injury on outcome from temporary focal cerebral ischemia in the rat.
(Journal of cardiothoracic and vascular anesthesia, 2013-02)<h4>Objective</h4>Acute kidney injury (AKI) and ischemic stroke may occur in the same cardiac surgical patient. It is not known if an interaction exists between these organ injuries. Isolated renal ischemia/reperfusion is ... -
