mice and the murine renal podocytes cell line(MPC-5)
and to explore the potential mechanism of

(ⅰ)
In vivo
. The

/
db
mice and littermate control

mice were used as the study objects. The
db
/
db
mice were divided into five groups according to their bodyweights
in which four groups were treated with
Yishen Tongluo
Formula (1.0
2.5
5.0 g/kg) or valsartan (10 mg/kg) once a day. The model group and the control group were given the same amount of distilled water. After 8 weeks of treatment
the number and morphology of podocytes in the kidney were assessed by transmission electron microscopy
and the podocyte marker protein (WT-1) was visulized by immunofluorescence and TUNEL staining. The serum levels of interleukin-1β (IL-1β) and interleukin-18(IL-18) were measured by enzyme-linked immunosorbent assay. The mRNA and protein expression and activation of NLRP3
CASP1 and GSDMD were measured by Q-PCR and Western blotting. (ⅱ)
In vitro
. MPC-5 cells induced with advanced glycation end products (AGEs). CCK-8 and lactate dehydrogenase (LDH) release detection techniques were used to detect LDH and evaluate the cell survival rate and membrane integrity. The mRNA levels of NLRP3
CASP1 and GSDMD in MPC-5 cells were measured by Q-PCR and Western blotting.

the mRNA levels of NLRP3
CASP1 and GSDMD were upregulated
the protein expression of NLRP3 was upregulated
and CASP1 and GSDMD were activated(
P

the number of TUNEL positive cells in renal tissue was decreased
and the serum IL-1β and IL-18 levels decreased. NLRP3
CASP1

IL-1β and IL-18 mRNA levels reduced
the protein expression of NLRP3 and inhibited CASP1 and GSDMD pathway activation(all
