Dendrobii Caulis Mixture-containing Serum Protects Mice from Podocyte Injury Induced by High Glucose
mixture (DMix)-containing serum on high glucose-induced podocyte injury in mice.
Method
2
The
MPC5 mouse glomerular podocytes were cultured
in vitro
, and the optimal glucose concentration for modeling, modeling time, and concentration of DMix-containing serum for administration were determined. The cells were classified into normal (5.5 mmol·L
Fer-1) groups. The corresponding kits were used to measure the levels of Fe
2+
and lactate dehydrogenase (LDH) in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione (GSH) and lipid peroxide (LPO) in cells. Fluorescence probe was used to measure the reactive oxygen species (ROS) level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels, respectively, of Wilms' tumor-1 (WT-1), desmin, long chain acyl-CoA synthase 4 (ACSL4), and glutathione peroxidase 4 (GPX4) in podocytes.
Result
2
Compared with the blank group, the intervention with 30 mmol·L
-1
glucose for 48 h reduced podocyte viability (
P
<
0.01), and the 10% DMix-containing serum showed the most significant improvement in podocyte viability (
P
<
0.01). Compared with the normal group, the model group presented elevated levels of Fe
2+
, LDH, LPO, and ROS, lowered GSH level, up-regulated mRNA and protein levels of desmin and ACSL4, and down-regulated mRNA and protein levels of WT-1 and GPX4 (
P
<
0.01). Compared with the model group, the DMix-containing serum lowered the Fe
2+
, LDH, LPO, and ROS levels, elevated the GSH level, down-regulated the mRNA and protein levels of desmin and ACSL4, and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes (
P
<
0.05,
P
<
0.01).
Conclusion
2
DMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.
