Rapamycin attenuates PLA2R activation-mediated podocyte apoptosis via the PI3K/AKT/mTOR pathway.

|
Primary MN has been associated with circulating antibodies against native podocyte antigens, including phospholipase A2 receptor (PLA2R); however, precision therapy targeting the signaling cascade of PLA2R activation is lacking.
|

|
We demonstrated that podocyte apoptosis was induced by Group IB secretory phospholipase A2 (sPLA2IB) in a concentration- and time-dependent manner via upregulation of phosphoinositide 3-kinase (PI3K), protein kinase B (AKT), and mTOR, and inhibited by rapamycin or LY294002.

|
Furthermore, aberrant activation of the PI3K/AKT/mTOR pathway triggers both extrinsic (caspase-8 and caspase-3) and intrinsic (Bcl-2-associated X protein [BAX], B-cell lymphoma 2 [BCL-2], cytochrome c, caspase-9, and caspase-3) apoptotic cascades in podocytes.
|

|
The therapeutic implications of our findings are that strategies to reduce PLA2R activation and PI3K/AKT/mTOR pathway inhibition in PLA2R-activated podocytes help protect podocytes from apoptosis.

Cdk5-Mediated Phosphorylation of Sirt1 Contributes to Podocyte Mitochondrial Dysfunction in Diabetic Nephropathy.
|
7 |
32660255
|
Results: Our results showed that the expression and activity of Cdk5 were significantly upregulated in vivo and in vitro under diabetic conditions, accompanied by the downregulation of synaptopodin and nephrin, as well as structural and functional mitochondrial dysfunction.
|
8 |
32660255
|
Inhibition of Cdk5 with roscovitine or dominant-negative Cdk5 led to the attenuation of podocyte injury by upregulating synaptopodin and nephrin.
|
9 |
32660255
|
The inhibition of Cdk5 also ameliorated mitochondrial dysfunction by decreasing reactive oxygen species levels and cytochrome c release, while increasing adenosine triphosphate production.
|
10 |
32660255
|
We demonstrated that HG levels cause overactive Cdk5 to phosphorylate Sirt1 at S47.
|
11 |
32660255
|
Suppression of Cdk5 reduced Sirt1 phosphorylation levels and mutation of S47 to nonphosphorable alanine (S47A), significantly attenuated podocyte injury and mitochondrial dysfunction in diabetic condition in vivo and in vitro.
|
12 |
32660255
|
Innovation and Conclusion: Our study has demonstrated the role of Cdk5 in regulating mitochondrial function through Sirt1 phosphorylation and thus can potentially be a new therapeutic target for DN treatment.

In addition, the expression of COXIV and cytochrome c was significantly downregulated in the Se-deficient group.
|
14 |
32172502
|
Importantly, the mRNA levels of silent mating type information regulation 2 homolog 1 (SIRT1) and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) and the protein levels of SIRT1 were increased in the Se-deficient group compared with the normal control group.
|

|
Moreover, the SIRT1/PGC1α axis likely plays an important role in the compensatory mechanism of mitochondrial dysfunction.

Resveratrol Reduces Oxidative Stress and Apoptosis in Podocytes via Sir2-Related Enzymes, Sirtuins1 (SIRT1)/Peroxisome Proliferator-Activated Receptor γ Co-Activator 1α (PGC-1α) Axis.
|
17 |
30765684
|
BACKGROUND PGC-1α can be activated by deacetylation reactions catalyzed by SIRT1.
|
18 |
30765684
|
However, it is unknown whether the renal-protective effect of resveratrol is further related to activation of the podocyte SIRT1/PGC-1α pathway.
|
19 |
30765684
|
The protein and mRNA expression levels of SIRT1, PGC-1α, NRF1, and TFAM were detect by immunofluorescence, Western blot analysis, and qRT-PCR in the podocytes, respectively.
|
20 |
30765684
|
RESULTS We found that high-glucose stimulation results in time-dependent decreases in the expression of SIRT1, PGC-1α, and its downstream genes NRF1 and mitochondrial transcription factor A (TFAM) for mouse podocytes, and increases ROS levels in cells and mitochondria.
|
21 |
30765684
|
In addition, it can also reduce the release of mitochondrial cytochrome C and DIABLO proteins to the cytoplasm and increase respiratory chain complex I and III activity and mitochondrial membrane potential.
|
22 |

|
CONCLUSIONS Resveratrol can reduce the oxidative damage and apoptosis of podocytes induced by high-glucose stimulation via SIRT1/PGC-1α-mediated mitochondrial protection.

SS-31 prevented oxidative stress and mitochondria-dependent apoptosis signalling by HOCl-alb in vivo and in vitro, as evidenced by the release of cytochrome c (cyt c), binding of apoptosis activated factor-1 (Apaf-1) and caspase-9, and activation of caspases.

Promoter analysis and chromatin immunoprecipitation studies revealed that putative KLF6 transcriptional binding sites are present in the promoter of the mitochondrial cytochrome c oxidase assembly gene (SCO2), which is critical for preventing cytochrome c release and activation of the intrinsic apoptotic pathway.

Furthermore, an obvious translocation of p-Smad3 from the cytosol to nuclei and induction of mitochondrial Nox4 were detected following PA application.
|
28 |
25229402
|
Induction of Nox4 by PA administration was significantly repressed by Smad3-shRNA, while Nox4-shRNA showed no effect on PA-induced p-Smad3 activation.
|
29 |
25229402
|
Notably, both Smad3 and Nox4 silencing significantly prevented the reduction of the mtDNA level, restored mitochondrial function, and decreased cellular apoptosis in PA-stimulated podocytes.
|
30 |
25229402
|
In conclusion, our findings demonstrated that Smad3-Nox4 axis-mediated mitochondrial dysfunction is involved in PA-induced podocyte damage likely via increasing ROS generation and activating the cytochrome c-caspase9-caspase3 apoptotic signaling pathway.

We studied the effects of 3,4-DGE on cultured human podocytes and in vivo in mice. 3,4-DGE induced apoptosis in podocytes in a dose- and time-dependent manner. 3,4-DGE promoted the release of cytochrome c from mitochondria and activation of caspase-3.
|
32 |
24337777
|
Intravenous administration of 3,4-DGE to healthy mice resulted in a decreased expression of HSP27/HSPB1 and caspase-3 activation in whole kidney and in podocytes in vivo.

In diabetic kidneys, tubulointerstitial nephritis antigen (TINag), voltage-dependent anion-selective channel (VDAC) 1, and VDAC2 were up-regulated in parallel with alterations in expression of proteins with functions in oxidative stress and oxidative phosphorylation (OxPhos) pathways.
