PAX8 and acute kidney injury: Surprisingly, here, we found the same result as in the human biopsy case of AKI due to rhabdomylosis: the strong PAX8 expression was induced after induction of ischemic AKI, both in normotensive and hypertensive rats, with expression present also in proximal tubular epithelial cells (Figure 4B,C), while in control, sham operated group, weak PAX8 expression was noticed in rare tubular epithelial cells (Figure 4A).
