Figure Lengend Snippet: Effect of STS pre-treatment on cell death in an in vitro model of hypoxia–reoxygenation injury. Rat kidney epithelial (NRK-52E) cells were exposed to 24 h of 37 °C hypoxia in serum-free media followed by reoxygenation in serum-positive media for 24 h at 37 °C. Control cells were cultured in serum-positive media under normoxic conditions for the same period. Cells were stained with FITC-Annexin V (apoptosis) and propidium iodide (necrosis) for analysis via flow cytometry. Experimental cells received no treatment or were treated with 150 μM STS for 2 h before hypoxia (STS Pre), during hypoxia (STS Hyp), or both before and during hypoxia (STS Pre + Hyp). ( a ) Mean cell death percentage (FITC-Annexin + and/or PI + ). ( b ) Mean apoptosis percentage (FITC-Annexin + /PI − ). ( c ) Mean necrosis percentage (FITC-Annexin V − /PI + ). Bars represent mean ± SEM (n = 4). Means were compared using one-way ANOVA and Tukey’s post hoc test. *** p < 0.001, **** p < 0.0001. STS: sodium thiosulfate.
Article Snippet: Since renal proximal tubular epithelial cells are particularly susceptible to IRI, rat kidney proximal tubular epithelial cells (NRK-52E, ATCC, USA) were used, which is also consistent with our in vivo rat model of kidney transplantation [ ].
