Leonurine, a major bioactive component from Herba Leonuri, shows therapeutic potential in several diseases, including diabetes, cardiovascular disease, bovine mastitis and depression. In kidney, it was reported that leonurine was performing a protective effect in both acute kidney injury and renal fibrosis mice models. The aim of this study is to investigate the effect of leonurine in podocyte injury. In the mice model of adriamycin (ADR) -induced nephropathy, the application of leonurine significantly prevented early kidney damage, macrophage infiltration and proteinuria. Meanwhile, leonurine suppressed ADR-induced podocyte injury and reactive oxygen species (ROS) production. Consistent to in vivo results, leonurine prevented ADR-induced podocyte injury and ROS production in cultured human podocytes. All these results suggested that leonurine might suppress ADR-induced podocyte injury via inhibiting oxidative stress. Leonurine might be a novel therapeutic drug for prevention of glomerular diseases.

Autophagy and Mitophagy in Diabetic Kidney Disease-A Literature Review.

Autophagy and mitophagy are critical cellular processes that maintain homeostasis by removing damaged organelles and promoting cellular survival under stress conditions. In the context of diabetic kidney disease, these mechanisms play essential roles in mitigating cellular damage. This review provides an in-depth analysis of the recent literature on the relationship between autophagy, mitophagy, and diabetic kidney disease, highlighting the current state of knowledge, existing research gaps, and potential areas for future investigations.

Several microRNAs (miRNAs) emerged as powerful regulators of fibrotic processes, "fibromiRs", and can also influence the expression of genes responsible for the generation of reactive oxygen species, "redoximiRs". We aimed to investigate whether plasma exosomes from hypertensive and diabetes patients are enriched in fibromiRs and redoximiRs using deep sequencing technology and their association with relevant signalling pathways implicated in oxidative stress and fibrogenesis by GO terms and KEGG pathways. RNA-Seq analysis from P-EXO identified 31 differentially expressed (DE) miRNAs in patients compared to controls, of which 77% are biofluid specific.

Diabetic kidney disease (DKD) is a leading cause of chronic kidney disease (CKD) and end-stage renal disease worldwide, affecting approximately 40% of individuals with type 2 diabetes (T2DM) and 30% of those with type 1 diabetes (T1DM). As the prevalence of diabetes continues to rise, the burden of DKD is expected to grow correspondingly. This review explores the roles of key molecular pathways, including the apelinergic system, vascular endothelial growth factor (VEGF)/VEGF receptor (VEGFR) axis, and nitric oxide (NO)/nitric oxide synthase (NOS) signaling, in DKD pathogenesis and potential therapeutic applications.

: Focal segmental glomerulosclerosis (FSGS) is a pattern of kidney injury with diverse causes and pathogeneses, resulting in podocyte injury and depletion. It can be classified as primary, genetic, or secondary. Because FSGS classically has a worse prognosis in patients with nephrotic syndrome, most studies have focused on the treatment and evolution of these patients, resulting in a lack of data related to patients without nephrotic syndrome.

The integrity of the filtration barrier of the kidney relies on the proper composition of podocyte interdigitating foot processes. Their architecture is supported by a complex actin-cytoskeleton. Following podocyte stress or injury, podocytes encounter structural changes, including rearrangement of the actin network and subsequent effacement of the foot processes.
