Fig. 6: HK2 overexpression attenuates UUO-induced kidney injury in HIF-1α CTAD−/− mice.

a qRT-PCR analysis of KIM-1 expression in the UUO kidney of HIF-1α CTAD−/− mice injected with Lv-HK2. The relative levels were normalized to β-actin (n = 6). b. Representative images of KIM-1 expression in kidney tissues were assessed by immunohistochemistry (n = 6). Scale bars, 50 µm. c Representative histological changes (PAS staining) (left, n = 6). Scale bars, 100 µm. The quantification of tubular injury based on PAS staining (right, n = 6). d mRNA expression of inflammatory factors (MCP-1, TNF-α, and IL-1β) in UUO kidney tissues from HIF-1α CTAD−/− mice with Lv-HK2 administration (n = 6). e Immunohistochemistry and semiquantitative population of F4/80+ macrophages infiltrating the kidneys (n = 6). Scale bars, 50 µm. **p-value < 0.01 versus Lv-NC. Data are presented as mean ± SEM of 6 mice. Lv-NC served as the control (t-test).
