1 · What the graph read from it

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.

2 · The registry

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

The malignant progression of colorectal cancer (CRC) is closely linked to metastasis and therapy resistance, but underlying mechanisms remain unclear. Here, we identify mitochondrial translocation of connexin 26 (Cx26) as a hallmark of highly malignant metastatic CRC and reveal its critical role in promoting ER-mitochondria crosstalk, calcium signaling, and epithelial-mesenchymal transition (EMT). Mechanistically, we demonstrate that protein L-isoaspartyl/D-aspartyl O-methyltransferase (PIMT) methylates Cx26 at asparagine 176, enhancing its mitochondrial localization and stability. This modification disrupts Cx26's gap junction function while activating calcium signaling to drive EMT and metastasis. Furthermore, we discovered that bortezomib (BTZ), contrary to its canonical proteasome inhibition mechanism, exhibits exceptional efficacy against highly malignant CRC by targeting the PIMT-Cx26 axis. BTZ directly binds PIMT, further amplifying Cx26 mitochondrial translocation and hyperactivating Ca
