BACKGROUND: Rab35 is a member of a GTPase family of endocytic trafficking proteins. Studies in cell lines have indicated that Rab35 participates in cell adhesion, polarity, cytokinesis, and primary cilia length and composition. Additionally, sea urchin Rab35 regulates actin organization and is required for gastrulation. In mice, loss of Rab35 in the CNS disrupts hippocampal development and neuronal organization. Outside of the CNS, the functions of mammalian Rab35 in vivo are unknown...

BACKGROUND: The synthetic tetra-peptide SS-31 shows promise in alleviating mitochondrial dysfunction associated with common diseases. However, the precise pharmacological basis of its mitoprotective effects remains unknown. METHODS: To uncover the biological targets of SS-31, we performed a genome-scale CRISPR screen in HK-2 cells, a cell culture model where SS-31 mitigates cisplatin-associated cell death and mitochondrial dysfunction. The identified hit candidate gene was functionally validated using knockout cell lines, siRNA mediated downregulation, and tubular epithelial specific conditional knockout mice...

BACKGROUND: The presence of a full house pattern at immunofluorescence on kidney biopsy in a patient without clinical and laboratory features of systemic lupus erythematosus (SLE) has led to the descriptive term non-lupus full house nephropathy. This systematic review and meta-analysis focus on non-lupus full house nephropathy nomenclature, clinical findings and outcomes. METHODS: In a reiterative process, all identified terms for non-lupus full house nephropathy and other MeSH terms were searched in PubMed...

BACKGROUND: To examine the association of use of different antivirals with hospital acquired acute kidney injury (AKI) among Chinese adults with herpes zoster. METHODS: The study selected 3273 adult patients who received antiviral therapy for herpes zoster during hospitalization from the China Renal Data System (CRDS). We identified and staged AKI using patient-level serum creatinine data according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria...

BACKGROUND: Older adults with kidney failure face preference-sensitive decisions regarding dialysis initiation. Despite recommendations, few older patients with kidney failure experience shared decision-making. Clinician uncertainty about the degree to which older patients prefer to engage in decision-making remains a key barrier. METHODS: Mixed-methods explanatory, longitudinal, sequential design at 4 diverse U.S. centers with patients (English-fluent, aged ≥70 years, CKD stages 4-5, nondialysis) from 2018 to 2020...

BACKGROUND: The kidney is involved in almost 100% of cases of AA amyloidosis, a rare disease caused by persistent inflammation with long overall survival but frequent progression to end-stage kidney failure . Identification of patients with advanced disease at diagnosis is difficult, given the absence of validated staging systems. METHODS: Newly diagnosed patients with AA amyloidosis from the Pavia (n=233, testing cohort) and Heidelberg (n=243, validation cohort) centers were included in the study...

BACKGROUND: A primary change to the national organ allocation system in 2014 for deceased donor kidney offers was to weight candidate priority based on sensitization (i.e. calculated panel reactive antibody percentage [CPRA%]) using a sliding scale. Increased priority for sensitized patients could improve equity in access to transplantation for disadvantaged candidates. We sought to evaluate the effect of these weights using a contemporary cohort of adult US kidney transplant candidates...

SIGNIFICANCE STATEMENT: The renal lymphatic vasculature and the lymphatic endothelial cells that make up this network play important immunomodulatory roles during inflammation. How lymphatics respond to AKI may affect AKI outcomes. The authors used single-cell RNA sequencing to characterize mouse renal lymphatic endothelial cells in quiescent and cisplatin-injured kidneys. lymphatic endothelial cell gene expression changes were confirmed in ischemia-reperfusion injury and in cultured lymphatic endothelial cells, validating renal lymphatic endothelial cells single-cell RNA sequencing data...

BACKGROUND: Renal fibrosis is a common pathological endpoint in CKD that is challenging to reverse, and myofibroblasts are responsible for the accumulation of a fibrillar collagen-rich extracellular matrix (ECM). Recent studies have unveiled myofibroblasts diversity in terms of proliferative and fibrotic characteristics, which are linked to different metabolic states. We previously demonstrated the regulation of ECM genes and tissue fibrosis by WWP2, a multifunctional E3 ubiquitin-protein ligase...

BACKGROUND AND AIM: Conflicts, akin to other crises, disrupt lives and healthcare infrastructure, disproportionately affecting vulnerable individuals. The ongoing Sudanese conflict, initiated on April 15, 2023, between the Sudanese Armed Forces (SAF) and the Rapid Support Force (RSF), triggers significant population displacement, healthcare facility closures, and a scarcity of medical resources. Amid the intense conflict in Khartoum, reports of deceased individuals in the streets heighten concerns about public health, emphasizing the gravity of the situation...

BACKGROUND: Lifelong kidney function relies on the complement of nephrons generated during mammalian development from a mesenchymal nephron progenitor cell population. Low nephron endowment confers increased susceptibility to chronic kidney disease. Reduced nephron numbers in the popular Six2TGC transgenic mouse line may be due to disruption of a regulatory gene at the integration site and/or ectopic expression of a gene(s) contained within the transgene. METHODS: Targeted locus amplification (TLA) was performed to identify the integration site of the Six2TGC transgene...
