Development of capsaicin-derived prohibitin ligands to modulate the Aurora kinase A/PHB2 interaction and mitophagy in cancer cells.

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
Aurora kinase A/AURKA is a serine/threonine kinase frequently overexpressed in cancer. Recent discoveries pointed to subcellular pools of AURKA, including at mitochondria. There, AURKA induces organelle clearance by mitophagy together with the autophagy mediator LC3, and its receptor PHB2.Here, we show that the natural product capsaicin modifies the AURKA/PHB2 interaction. We synthesize 16 capsaicin analogs, and Förster's Resonance Energy Transfer/Fluorescence Lifetime Imaging Microscopy (FRET/FLIM) in breast cancer cells reveals that compounds 12 and 13 increase the AURKA/PHB2 interaction. Molecular docking shows that they bind to the inhibitory pocket of PHB2 and to the AURKA active site. We demonstrate that compound 13 specifically inhibits mitophagy while leaving AURKA activation unaltered at centrosomes. Our results demonstrate that compound 13 is a PHB ligand acting on the AURKA/PHB2 interaction. Thanks to its specificity, it may lead to the development of anticancer drugs targeting the mitochondrial functions of AURKA.
