Figure Lengend Snippet: Fig. 7. Schematic illustration shows the mechanisms of TZ inhibition on AAA formation. Stress induces the expression of Peg3 in VSMCs, triggering VSMCs senescence, apoptosis, and ECM degradation, eventually leading to AAA formation Treatment with low-dose TZ reduces Peg3 expression, reversing these effects. The picture was drawn by Figdraw. VSMCs, vascular smooth muscle cells. SASP, senescence-associated secretory phenotype. ECM, extracellular matrix.
