The purpose of our study was to better understand the relationship between mitochondrial structural proteins, particularly dynamin-related protein 1 (Drp1) and amyloid beta (Aβ) in the progression of Alzheimer's disease (AD). Using qRT-PCR and immunoblotting analyses, we measured mRNA and protein levels of mitochondrial structural genes in the frontal cortex of patients with early, definite and...

Mitochondria are essential for cell growth, fission, differentiation, and survival, particularly in undivided cells with high energy requirements, such as cardiomyocytes. The morphology position of mitochondria change the activity mitochondrial fission proteins fusion proteins. These regulatory mechanisms substantially affect cardiomyocyte supply normal function. In dynamin-related protein 1 (D...

Abstract Mitochondrial fusion and fission, which are strongly related to normal mitochondrial function, referred as dynamics. defects in the liver cause a non-alcoholic steatohepatitis-like phenotype cancer. However, whether fission defect directly impair function stimulate disease progression, too, is unclear. Dynamin-related protein 1 (DRP1) key factor controlling fission. We hypothesized tha...

Dynamin-related protein 1 (Drp1) is a member of the dynamin family of large GTPase, which cycles between the cytosol and the mitochondrial outer membrane, and mediates mitochondrial fission. Using microarray analysis of gene expression in the livers of wild-type and Drp1 knockout mice, we have previously identified that endoplasmic reticulum (ER) stress marker genes are significantly increased ...

Androgen and androgen receptors (AR) play critical roles in the proliferation of prostate cancer through transcriptional regulation of target genes. Here, we found that androgens upregulated the expression of dynamin-related protein 1 (Drp1), which is involved in the induction of mitochondrial fission, a common event in mitosis and apoptosis. Clinical tissue samples and various prostate cancer ...

Mitochondria in cells comprise a tubulovesicular reticulum shaped by dynamic fission and fusion events. The multimeric dynamin-like GTPase Drp1 is a critical protein mediating mitochondrial division. It harbors multiple motifs including GTP-binding, middle, and GTPase effector (GED) domains that are important for both intramolecular and intermolecular interactions. As for other members of the d...

Cardiolipin (CL) is an atypical, dimeric phospholipid essential for mitochondrial dynamics in eukaryotic cells. Dynamin-related protein 1 (Drp1), a cytosolic member of the dynamin superfamily of large GTPases, interacts with CL and functions to sustain the balance of mitochondrial division and fusion by catalyzing mitochondrial fission. Although recent studies have indicated a role for CL in st...

BACKGROUND Alzheimer's disease (AD) is one of the most common neurodegenerative disorders. Recent studies have shown that mitochondrial dysfunction is a causative factor of AD. Drp1 (Dynamin-related protein 1), a regulator of mitochondrial fission, shows neuroprotective effects on Parkinson's disease. In this study, we investigate the effect and mechanism of Drp1 on Aβ42 transgenic Drosophila. ...

Mitochondrial fission facilitates cytochrome c release from the intracristae space into the cytoplasm during intrinsic apoptosis, although how the mitochondrial fission factor Drp1 and its mitochondrial receptors Mff, MiD49, and MiD51 are involved in this reaction remains elusive. Here, we analyzed the functional division of these receptors with their knockout (KO) cell lines. In marked contras...

Objective: Mitochondrial content and function are important determinants of oxidative capacity and metabolic efficiency of skeletal muscle tissue. The aim of this study was to investigate the changes in mitochondrial dynamic factors (mfn2 and drp1) following high intensity interval training (HIIT) and moderate intensity continuous training (MICT) in obese male rats. Materials and Methods: In t...
