Does Nonsteroidal Anti-inflammatory Drug Use Modify All-Cause and Cause-Specific Mortality Associated with PM and Its Components? A Nationally Representative Cohort Study (2007-2017).

Several studies reported that nonsteroidal anti-inflammatory drug (NSAID) use could alleviate subclinical effects of short-term exposure to fine particulate matter (PM). However, whether chronic NSAID use could mitigate the long-term effects of PM and its components on population mortality has been unknown. Based on a national representative survey of 47,086 adults (2007-2010) with follow-up information on the primary cause of death (until 2017), we investigated the long-term associations of PM and its major components, including black carbon (BC), ammonium (NH ), nitrate (NO ), organic matter (OM), and sulfate (SO ), with all-cause and cause-specific mortality using the Cox proportional hazards model.

Methyltransferase-like 3 mediates m6A modification of heme oxygenase 1 mRNA to induce ferroptosis of renal tubular epithelial cells in acute kidney injury.

Renal tubular S100A7a impairs fatty acid oxidation and exacerbates renal fibrosis via both intracellular and extracellular pathway.

A couple of S100 family proteins (S100s) have been reported to exert pro-inflammatory functions in the progression of renal fibrosis. Unlike some S100s which are expressed by both epithelial and stromal inflammatory cells, S100A7 is restricted expressed in epithelium. Persistent S100A7 expression occurs in some invasive carcinomas and is associated with poor prognostic factors.

Advancing the clinical assessment of glomerular podocyte pathology in kidney biopsies via super-resolution microscopy and angiopoietin-like 4 staining.

The tertiary structure of normal podocytes prevents protein from leaking into the urine. However, observing the complexity of podocytes is challenging because of the scale differences in their three-dimensional structure and the close proximity between neighboring cells in space. In this study, we explored podocyte-secreted angiopoietin-like 4 (ANGPTL4) as a potential morphological marker via super-resolution microscopy (SRM).

Inhibition of HIF-prolyl hydroxylase promotes renal tubule regeneration via the reprogramming of renal proximal tubular cells.
