Dynamin-related protein 1 (Drp1) is essential for mitochondrial and peroxisomal fission. Recent studies propose that Drp1 does not sever but rather constricts mitochondrial membranes allowing dynamin 2 (Dnm2) to execute final scission. Here, we report that unlike Drp1, Dnm2 is dispensable for ...
Recent studies have demonstrated that dynamin-related protein 1 (Drp1), a mitochondrial fission protein, mediates mitochondria-dependent apoptosis through mitochondrial division. However, little is known about the mechanism by which Drp1 modulates apoptosis in response to chlorpyrifos (CPF)-induced toxicity...
related protein-1 (Drp1), thereby decreasing Drp1 accumulation in mitochondria and Drp1-mediated activation of the mitochondrial fission program. We also found that p53 transcriptionally downregulates miR-499 expression. Our data reveal a role for miR-499 in regulating the mitochondrial fission machinery...
Bioinformatics technology was used to analyze the expression level of dynamin-related protein 1 (DRP1), a key protein of mitochondrial division. The effects of DRP1 and DRP1 inhibitor (mdivi-1) on the proliferation and migration of liver cancer cells BEL-7402 were observed using cell counting kit...
related protein (Drp1). In healthy exercised hearts, the redox-sensitive Cys644 of Drp1 is highly S-glutathionylated. Nearly 40% of Cys644 is normally polysulfidated, which is a preferential target for GSSG-mediated S-glutathionylation. Cys644 S-glutathionylation is resistant to Drp1 depoly...
The large cytosolic GTPase, dynamin-related protein 1 (Drp1), mediates both physiological and pathological mitochondrial fission. Cell stress triggers Drp1 binding to mitochondrial Fis1 and subsequently, mitochondrial fragmentation, ROS production, metabolic collapse, and cell death. Because Drp1 also medi...
Mdivi-1是一个具有选择性和细胞穿膜性的线粒体分裂抑制剂,抑制了DRP1(发动蛋白相关GTP酶)和Dynamin I (Dnm1)的IC50为1-10 μM。 靶点(IC50 & Targe) Dnm1 GTPase,1μM-10μM 体外研究 Mdivi-1是一个可以穿越细胞膜的喹唑酮类化合物,抑制了酵母的Dnm1和人源的Drp1分裂DRPs(发动蛋白相关GTP酶),并且高...
We have previously demonstrated a therapeutic effect of peptide P110, a 7-amino acid peptide representing a homology sequence between dynamin-related protein 1 (Drp1) and Fission 1 (Fis1) [21], in reducing pathological mitochondrial dysfunction in multiple neurodegenerative diseases [20, 22,23,24...
(HUVECs), which accelerated dynamin-related protein 1 (Drp1)-mediated mitochondrial fission. Silencing MiD49/51 reduced atherosclerotic plaque size, increased collagen content, and decreased the IL-8-induced adhesion and proliferation of HUVECs. MiD51 upregulation resulted from decreased microRNA (miR...
However, the enhanced cellular sensitivity to cisplatin by mdivi-1 was also observed in Drp1 (a mitochondrial fission protein and the supposed target of mdivi-1) knockout MEF cells, indicating Drp1-independent roles of these compounds in overcoming platinum drug resistance. The combination of ...
