Article Abstract
Cyclosporin A (CsA) is a common immunosuppressant, but its use is limited as it can cause chronic kidney injury. Oxidative stress and apoptosis play a key role in CsA-induced nephrotoxicity. This study investigated the protective effect of 5-aminolevulinic acid and iron (5-ALA/SFC) on CsA-induced injury in murine proximal tubular epithelial cells (mProx24). 5-ALA/SFC significantly inhibited apoptosis in CsA-treated mProx24 cells with increases in heme oxygenase (HO)-1, nuclear factor E2-related factor 2 (Nrf2), and p38, and Erk-1/2 phosphorylation. Moreover, 5-ALA/SFC suppressed production of reactive oxygen species in CsA-exposed cells and inhibition of HO-1 suppressed the protective effects of 5-ALA/SFC. In summary, 5-ALA/SFC may have potential for development into a treatment for the anti-nephrotoxic/apoptotic effects of CsA.

The interaction between renal intrinsic cells and macrophages plays a crucial role in the onset and progression of kidney diseases. In recent years, epigenetic mechanisms such as DNA methylation, histone modification, and non-coding RNA regulation have become essential windows for understanding these processes. This review focuses on how renal intrinsic cells (including tubular epithelial cells, podocytes, and endothelial cells), renal cancer cells, and mesenchymal stem cells influence the function and polarization status of macrophages through their own epigenetic alterations, and how the epigenetic regulation of macrophages themselves responds to kidney damage, thus participating in renal inflammation, fibrosis, and repair.

The purpose of this study was to investigate whether RIPK3-mediated programmed cell death can promote the replication and transmission of renal infectious bronchitis virus in renal tubular epithelial cells. Primary renal tubular epithelial cells were extracted from 1 to 7 day old Hy-Line Brown chicks, cultured in vitro by type I collagenase digestion, and infected with 1MOI SX9 strain. Cell samples were collected at 12 hpi, 24 hpi, 36 hpi and 48 hpi for experimental exploration.

Unlabelled: Periodontitis is closely related to renal health, but the specific influence of (), a key pathogen in periodontitis, on the development of acute kidney injury (AKI) in mice has not been fully elucidated. In our study, AKI was induced in mice through ischemia-reperfusion injury while administering oral infection with . Comprehensive analyses were conducted, including 16S rRNA sequencing, liquid chromatography-mass spectrometry (LC-MS) metabolomics, and transcriptome sequencing.

Common pancreatobiliary epithelial malignancies such as pancreatic ductal adenocarcinoma, cholangiocarcinoma and gallbladder carcinoma have poor prognosis. A small but significant portion of these malignancies arise from mass-forming grossly and radiologically visible premalignant epithelial neoplasms in the pancreatobiliary tree. Several lesions, including a few recently described entities, fall under this category and predominantly include papillary epithelial lesions with or without mucin production.

Background: Acute kidney injury (AKI) is a life-threatening clinical syndrome with no effective treatment currently available. This study aims to investigate whether Iron-Quercetin complex (IronQ) pretreatment can enhance the therapeutic efficacy of Mesenchymal stem cells (MSCs) in AKI and explore the underlying mechanisms.
Methods: A cisplatin-induced AKI model was established in male C57BL/6 mice, followed by the intravenous administration of 1x10ˆ6 MSCs or IronQ-pretreated MSCs (MSC).
