Abnormal lipid metabolism associated with various renal diseases has been known for a long time. Hypercholesterolemia is one of the characteristic features of nephotic syndrome, and hypertriglyceridemia is often observed in chronic renal failure (CRF). The role of lipid abnormalities in the pathogenesis of renal diseases has been variously discussed. However, direct evidence only recently became possible when more sophisticated analyses of renal histopathology as well as an application of molecular biology were introduced in the field of clinical nephrology. The recent identification of lipoprotein nephropathy (LPG), reported most often by Japanese authors since 1989, is particularly noteworthy. The detailed analysis of lipid profiles and renal histology has been instrumental in clarifying the relationship between lipids and the kidney not only in LPG but also in other disease entities such as familial-type dyslipidemias, CRF, focal glomerulosclerosis, and diabetic nephropathy. Dyslipidemias common to these diseases, together with the presence of hypertension, cause systemic atherosclerotic lesions (including lesions in the kidney) and terminal renal failure.

Klotho is highly expressed in the kidney, while soluble Klotho is detectable in the blood, urine, and cerebrospinal fluid, and has multiple hormone-like functions. The role of Klotho in kidney injury has attracted more and more attentions from researchers. Emerging evidence revealed that the transient deficiency of Klotho is an early event of acute kidney injury (AKI), whereas, in chronic kidney disease, this deficiency is sustained not only in the kidney, but also in other organ systems. Therefore, Klotho could be a potential biomarker for early diagnosis of AKI, as well as for its progression to chronic kidney disease. Moreover, Klotho might have therapeutic value to renal injury. Nevertheless, there are only few studies on the involvement of Klotho in post AKI repair. This review focused on the role of Klotho in not only kidney injury, but also its repair, in particular the relationship between Klotho and cell fate (autophagy/apoptosis/necrosis), repair/regeneration, Wnt/β-catenin and erythropoietin receptor, one of the Klotho effectors.

Acute kidney injury (AKI) refers to a clinical syndrome in which renal function declines rapidly in a short period of time caused by various pathological factors. During the development of AKI, renal tubules with the functions of reabsorption and excretion are prone to cell death due to external pathological stimuli, which is an important cause of impaired renal function. In recent years, a variety of new cell death pathways have been gradually recognized. Researchers have now found that regulated cell death (RCD), such as necroptosis, pyroptosis and ferroptosis, are important regulatory mechanisms of AKI. This article will summarize the research advances of various types of RCD involved in the process of AKI, aiming to deepen the understanding of AKI and provide innovative thoughts for the clinical treatment of AKI.

Vascular endothelial growth factor-A (VEGF-A) is a critical angiogenic factor which is mainly secreted from podocytes and epithelial cells in kidney and plays an important role in renal pathophysiology. In recent years, functions of different isoforms of VEGF-A and the new secretion approach via extracellular vesicles (EVs) have been identified. Thus, further understanding are needed for the role of VEGF-A and its isoforms in renal injury and repair. In this review, we summarized the expression, secretion and regulation of VEGF-A, its biological function, and the role of different isoforms of VEGF-A in the development of different renal diseases. Meanwhile, the research progress of VEGF-A as diagnostic marker and therapeutic target for renal diseases were discussed.
