Mitochondrial Dysfunction and Signaling in Diabetic Kidney Disease: Oxidative Stress and Beyond
Summary: The kidneys are highly metabolic organs that produce vast quantities of adenosine triphosphate via oxidative phosphorylation and, as such, contain many mitochondria. Although mitochondrial reactive oxygen species are involved in many physiological processes in the kidneys, there is a plethora of evidence to suggest that excessive production may be a pathologic mediator of many chronic kidney diseases, including diabetic kidney disease. Despite this, results from clinical testing of antioxidant therapies have been generally underwhelming. (Source: Seminars in Nephrology)

The Warburg Effect in Diabetic Kidney Disease
Summary: Diabetic kidney disease (DKD) is the leading cause of morbidity and mortality in diabetic patients. Defining risk factors for DKD using a reductionist approach has proven challenging. Integrative omics-based systems biology tools have shed new insights in our understanding of DKD and have provided several key breakthroughs for identifying novel predictive and diagnostic biomarkers. In this review, we highlight the role of the Warburg effect in DKD and potential regulating factors such as sphingomyelin, fumarate, and pyruvate kinase muscle isozyme M2 in shifting glucose flux from complete oxidation in mitochondria ...

The Role of Peroxisome Proliferator-Activated Receptor γ Coactivator 1α (PGC-1α) in Kidney Disease
Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is a key transcriptional regulator of mitochondrial biogenesis and function. Several recent studies have evaluated the role of PGC-1α in various renal cell types in healthy and disease conditions. Renal tubule cells mostly depend on mitochondrial fatty acid oxidation fo r energy generation. A decrease in PGC-1α expression and fatty acid oxidation is commonly observed in patient samples and mouse models with acute and chronic kidney disease. (Source: Seminars in Nephrology)

Metabolomics and Metabolic Reprogramming in Kidney Cancer
Kidney cancer, or renal cell carcinoma (RCC), is a disease of increasing incidence that commonly is seen in the general practice of nephrology. Despite this state of affairs, this fascinating and highly morbid disease frequently is under-represented, or even absent, from the curriculum of nephrologists in training and generally is underemphasized in national nephrology meetings, both scientific as well as clinical. Although classic concepts in cancer research in general had led to the concept that cancer is a disease resulting from mutations in the control of growth-regulating pathways, reinforced by the discovery of oncog...

Targeting Glucosylceramide Synthesis in the Treatment of Rare and Common Renal Disease
Summary: Sphingolipids, including ceramides, glycosphingolipids, sphingomyelin, and sphingosine-1-phosphate, have been recognized as important molecules that regulate critical cellular functions. Although originally studied in the context of lysosomal storage diseases, the roles of these compounds in more common disorders involving metabolism, vascular disease, and aberrant growth has been the focus of recent studies, including in disorders that affect the kidneys. These efforts have led to new insights into Fabry disease, a classic disorder of lysosomal function that results in renal failure as well as in more common rena...

Contributory Role of Gut Microbiota and Their Metabolites Toward Cardiovascular Complications in Chronic Kidney Disease
Summary: The gut microbiome recently has emerged as a novel risk factor that impacts health and disease. Our gut microbiota can function as an endocrine organ through its unique ability to metabolize various dietary precursors, and can fuel the systemic inflammation observed in chronic disease. This is especially important in the setting of chronic kidney disease, in which microbial metabolism can contribute directly to accumulation of circulating toxins that then can alter and shift the balance of microbiota composition and downstream functions.

Genome-Wide Association Studies of Metabolite Concentrations (mGWAS): Relevance for Nephrology
Metabolites are small molecules that are intermediates or products of metabolism, many of which are freely filtered by the kidneys. In addition, the kidneys have a central role in metabolite anabolism and catabolism, as well as in active metabolite reabsorption and/or secretion during tubular passage. This review article illustrates how the coupling of genomics and metabolomics in genome-wide association analyses of metabolites can be used to illuminate mechanisms underlying human metabolism, with a special focus on insights relevant to nephrology.

Introduction: Systems Biology of Kidney Disease
The progression from linear hypothesis testing to a broad, unbiased view of biological disturbances is fast upon us. Nephrology has been somewhat slow to move from a strict physiology- and hemodynamic-based discipline to the molecular age and has lagged behind with respect to novel therapeutics and diagnostics. However, in the past few years, nephrology has been moving forward rapidly to embrace Big Data and multi-omic tools. Moving toward a systems biology perspective is a major step forward.

Phenotyping of Acute Kidney Injury: Beyond Serum Creatinine
Summary: Acute kidney injury (AKI) is a common complication in hospitalized patients and is associated with adverse short- and long-term outcomes. AKI is diagnosed by serum creatinine (SCr)-based consensus definitions that capture an abrupt decrease in glomerular filtration rate associated with AKI. However, SCr-based AKI definitions lack sensitivity and specificity for diagnosing structural kidney injury. Moreover, AKI is a heterogeneous condition consisting of distinct phenotypes based on its etiology, prognosis, and molecular pathways, and that may potentially require different therapies.

Summary: The renal biopsy provides critical diagnostic and prognostic information to clinicians including cases of acute kidney injury, chronic kidney disease, and allograft dysfunction. Today, biopsy specimens are read using a combination of light microscopy, electron microscopy, and indirect immunofluorescence, with a limited number of antibodies. These techniques all were perfected decades ago with only incremental changes since then. By contrast, recent advances in single-cell genomics are transforming scientists' ability to characterize cells. (Source: Seminars in Nephrology)

Precision Medicine for Acute Kidney Injury (AKI): Redefining AKI by Agnostic Kidney Tissue Interrogation and Genetics
Summary: Acute kidney injury (AKI) currently is diagnosed by a temporal trend of a single blood analyte: serum creatinine. This measurement is neither sensitive nor specific to kidney injury or its protean forms. Newer biomarkers, neutrophil gelatinase-associated lipocalin (NGAL, Lipocalin 2, Siderocalin), or kidney injury molecule-1 (KIM-1, Hepatitis A Virus Cellular Receptor 1), accelerate the diagnosis of AKI as well as prospectively distinguish rapidly reversible from prolonged causes of serum creatinine increase.

Proteomics and Metabolomics for AKI Diagnosis
Acute kidney injury (AKI) is a severe and frequent condition in hospitalized patients. Currently, no efficient therapy of AKI is available. Therefore, efforts focus on early prevention and potentially early initiation of renal replacement therapy to improve the outcome in AKI. The detection of AKI in hospitalized patients implies the need for early, accurate, robust, and easily accessible biomarkers of AKI evolution and outcome prediction because only a narrow window exists to implement the earlier-described measures.

Translating Knowledge Into Therapy for Acute Kidney Injury
Summary: No therapies have been shown to improve outcomes in patients with acute kidney injury (AKI). Given the high morbidity and mortality associated with AKI this represents an important unmet medical need. A common feature of all of the therapeutic development efforts for AKI is that none were driven by target selection or preclinical modeling that was based primarily on human data. This is important when considering a heterogeneous and dynamic condition such as AKI, in which in the absence of more accurate molecular classifications, clinical cohorts are likely to include patients with different types of injury at diff...

Introduction: Understanding Human AKI
A deep frustration for many who care for patients with acute kidney injury (AKI) is the lack of development of new therapies that directly limit kidney damage and/or enhance subsequent functional repair. For many years we have been telling patients with AKI that we can use modalities such as dialysis to keep them alive while we wait for the kidneys to undergo repair and regeneration. Unfortunately, in too many cases, that innate repair process is either slow to occur, resulting in prolonged hospital stays, or inadequate to restore kidney function, leading to the need for chronic dialysis.

Introduction: APOL1-Associated Kidney Disease
African Americans develop kidney failure at rates four to five times higher than European Americans. Although older reports have hinted at this disparity for some time, it was neither widely appreciated nor reliably quantified until relatively recently. It is hard to overstate the importance of this difference in kidney disease risk. Almost 40% of dialysis patients in the United States are African American. If this disparity could be reduced, there would be an enormous increase in health and decrease in heath care expenditures (Source: Seminars in Nephrology)

Summary: Common DNA sequence variants rarely have a high-risk association with a common disease. When such associations do occur, evolutionary forces must be sought, such as in the association of apolipoprotein L1 (APOL1) gene risk variants with nondiabetic kidney diseases in populations of African ancestry.

However, the homozygous state is disadvantageous and is associated with a markedly increased risk of a spectrum of kidney diseases en...

A Brief History of APOL1: A Gene Evolving
Summary: APOL1 kidney risk variants lead to high rates of kidney disease in people of recent African ancestry. These risk variants are very common and confer a large increase in risk of kidney disease. This unusual combination of high frequency and large effect size occurs because the risk variants also appear to have beneficial properties. The risk variants show enhanced protective effects against certain pathogens, particularly the trypanosomes that cause African sleeping sickness. Here, we consider the origins and evolution of the primate-only APOL1 gene. (Source: Seminars in Nephrology)

Apolipoprotein L1 Gene Effects on Kidney Transplantation
The pathogenesis of many common etiologies of nephropathy has been informed by recent molecular genetic breakthroughs. It now is apparent that the ethnic disparity in the risk for nondiabetic chronic kidney disease between African Americans and European Americans is explained largely by variation in the apolipoprotein L1 gene (APOL1). The presence of two APOL1 renal risk variants markedly increases an individual ’s risk for kidney disease. In transplantation, kidneys from deceased African Americans with two APOL1 renal risk variants have shorter survival intervals after engraftment, regardless of the ethnicity of the...

Summary: End-stage renal disease (ESRD) disproportionately affects African Americans, who are two to four times more likely than European Americans to develop ESRD. Two independent variants of the apolipoprotein L1 (APOL1) gene, G1 and G2, have been associated with a 7- to 10-fold greater risk of developing nondiabetic ESRD in African Americans. Those who inherit two risk variants (G1/G1, G2/G2, or G1/G2) are also more likely to develop ESRD at a younger age and to have progression of chronic kidney disease. (Source: Seminars in Nephrology)

The role of immunosuppression in IgAN remains controversial despite a growing evidence base of randomized controlled trials (RCTs). In IgAN with nephrotic syndrome the role for corticosteroids is limited to cases with minimal change on light microscopy. In crescentic IgAN, the use of immunosuppression is supported only by anecdotal data, and outcome may be poor especially when glomerular filtration rate is impaired severely at presentation or there are pathologic features of chronic injury. In slowly progressive IgAN, prediction of outcome now is based both on clinical and pathologic features. (Source: Seminars in Nephrology)

Preterm birth occurs in approximately 10% of all births worldwide. Preterm infants have reduced nephron numbers at birth in proportion to gestational age, and are at increased risk of neonatal acute kidney injury as well as higher blood pressure, proteinuria, and chronic kidney disease later in life. Rapid catch-up growth in preterm infants, especially if resulting in obesity, is a risk factor for end-stage kidney disease among children with proteinuric renal disease. Preterm birth, however, is a risk factor not only for the infant because mothers who deliver preterm have an increased risk of having subsequent preterm deli...

Summary: The prevalence of chronic or end-stage kidney disease in pediatric girls is lower than in boys, however, girls have unique morbidities that can have great effect on their quality of life. For female adolescents, creatinine excretion peaks at approximately 14 years of age and is significantly less than males, owing to lower muscle mass. Females have higher nitric oxide activity, and estrogens may contribute to lower blood pressure. Females excrete less growth hormone during the prepubertal and pubertal years.
