Figure Lengend Snippet: Schematic illustration of the mechanism whereby circAASS regulates mitochondrial homeostasis in kidney injury and renal fibrosis. Under normal conditions, cytoplasm-localized circAASS acts as a ceRNA by sequestering MIR324-3p , thus maintaining the expression of PINK1 and promoting mitophagy; nucleus-localized circAASS directly interact with the PPARGC1A/PGC-1α protein, inhibiting its ubiquitin-mediated degradation and thereby facilitating post-translational modifications that promote mitochondrial biogenesis. Under Aki conditions, low-expression of circAASS inhibits mitophagy and mitochondrial biogenesis, thereby causing pro-fibrotic and pro-inflammatory effects of TECs.
