Drp1-dependent mitochondrial fission in cardiovascular disease

Acta Pharmacologica Sinica, 2020
Mitochondria are highly dynamic organelles undergoing cycles of fusion and fission to modulate their morphology, distribution, and function, which are referred as 'mitochondrial dynamics'. Dynamin-related protein 1 (Drp1) is known as the major pro-fission protein whose activity is tightly regulated to clear the damaged mitochondria via mitophagy ...

AMPK/Drp1 Pathway Mediates Streptococcus Uberis-Induced Mitochondrial Dysfunction

SSRN Electronic Journal, 2022
Excessive production of reactive oxygen species (ROS) leads to oxidative stress in host cells and affects the progress of disease. Mitochondria are an important source of ROS and their dysfunction is closely related to ROS production. S. uberis is a common causative agent of mastitis. The expression of key enzymes of the mitochondrial apoptotic pathway

Drp1-Zip1 Interaction Regulates Mitochondrial Quality Surveillance System [PDF]

open access: yesMolecular Cell, 2019
Mitophagy, a mitochondrial quality control process for eliminating dysfunctional mitochondria, can be induced by a response of dynamin-related protein 1 (Drp1) to a reduction in mitochondrial membrane potential (MMP) and mitochondrial division. However, the coordination between MMP and mitochondrial division for selecting the damaged portion of the ...

Abstract P3178: Gja1-20k Is Downstream Of Drp1 And Can Rescue Drp1 Suppression In Mouse Heart

Circulation Research, 2023
Dynamin-Related Protein 1 (DRP1) is a major mediator of mitochondrial fission and its mutation results with hyper-fused mitochondria and, in mice, a dilated cardiomyopathy. GJA1-20k is the most abundant N-terminus truncated isoform of Connexin 43 (Cx43) formed by internal translation and was originally identified as a trafficking subunit of Cx43.

Recruitment of Drp1 in Mitochondrial Fission

The FASEB Journal, 2017
Intracellular membranes are dynamically shaped by proteins including fission and fusion events important for vesicular transport, organelle trafficking, and cellular homeostasis. Yet how proteins interact with membranes to control these events is largely unknown.

Drp1 in Ischemic Neuronal Death: An Unusual Suspect

Current Medicinal Chemistry, 2014
Mitochondria play a crucial role in multitude of cellular processes including energy production, calcium signaling, and apoptosis. This remarkable organelle constantly undergoes a complex cycle of fusion and fission, a crucial quality control system for maintaining homeostasis of the cell.
