Mitochondrial fission and mitophagy depend on cofilin-mediated actin depolymerization activity at the mitochondrial fission site.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mitochondria fission and mitophagy are fundamentally crucial to cellular physiology and play important roles in cancer progression. Developing a comprehensive understanding of the molecular mechanism underlying mitochondrial fission and mitophagy will provide novel strategies for cancer prevention and treatment. Actin has been shown to participate in mitochondrial fission and mitophagy regulation. Cofilin is best known as an actin-depolymerizing factor. However, the molecular mechanism by which cofilin regulates mitochondrial fission and mitophagy remains largely unknown. Here we report that knockdown of cofilin attenuates and overexpression of cofilin potentiates mitochondrial fission as well as PINK1/PARK2-dependent mitophagy induced by staurosporine (STS), etoposide (ETO), and carbonyl cyanide 3-chlorophenylhydrazone (CCCP). Cofilin-mediated-PINK1 (PTEN-induced putative kinase 1) accumulation mainly depends on its regulation of mitochondrial proteases, including peptidase mitochondrial processing beta (MPPβ), presenilin-associated rhomboid-like protease (PARL), and ATPase family gene 3-like 2 (AFG3L2), via mitochondrial membrane potential activity. We also found that the interaction and colocalization of G-actin/F-actin with cofilin at mitochondrial fission sites undergo constriction after CCCP treatment. Pretreatment with the actin polymerization inhibitor latrunculin B (LatB) increased and actin-depolymerization inhibitor jasplakinolide (Jas) decreased mitochondrial translocation of actin induced by STS, ETO, and CCCP. Both LatB and Jas abrogated CCCP-mediated mitochondrial fission and mitophagy. Our data suggest that G-actin is the actin form that is translocated to mitochondria, and the actin-depolymerization activity regulated by cofilin at the mitochondrial fission site is crucial for inducing mitochondrial fission and mitophagy.
