The original version of this Article contained an error in Figure 5, where the images labeled "5 mM 24 h" and "5 mM 48 h" were inadvertently duplicated due to a labeling error during data organization.

The original Figure 5 and accompanying legend appear below.

In vitro: High Ca2+ upregulates the expression of pyroptosis- and adhesion-related proteins in a concentration- and time-dependent manner. The microstructural changes of cells in the 5mM, 10 mM, and 20 mM Ca2+ groups: abnormal cell morphology, local damage to the cell membrane (red arrow), cell–matrix overflow, free organelles in some areas (green arrow) and many vacuoles (blue arrow) using a transmission electron microscopy (a). Pyroptosis- and adhesion-related protein expression in the HK-2 cells using Western Blot images and their graphical quantification (b) and ELISA (c). *p < 0.05; **p < 0.01; ***p < 0.001.
