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

Cancer cells frequently reside in a glucose-deprived microenvironment due to rapid tumor proliferation and insufficient angiogenesis. However, the mechanisms by which colorectal cancer cells (CRC) adapt to glucose starvation to sustain proliferation remain unclear. Succinylation, a novel post-translational modification, has been implicated in regulating tumor cell proliferation and survival under nutrient stress. Our study reveals that fumarate hydratase (FH), a key enzyme in the tricarboxylic acid (TCA) cycle, is downregulated in CRC and acts as a tumor suppressor. Under glucose starvation mimicked in vitro, FH protein expression is reduced, leading to abnormal accumulation of its upstream metabolites fumarate and succinate, which correlates with advanced clinical stage and poor prognosis in CRC patients. Mechanistically, accumulated fumarate specifically binds to and stabilizes the NRF2 protein, upregulating the expression of GPX4 and FTH1 to inhibit ferroptosis, thereby sustaining CRC cell proliferation. Meanwhile, glucose starvation induces CPT1A-mediated succinylation of FH at residues K66/K80, reducing FH protein stability and promoting its degradation via the autophagy-lysosome pathway. Our findings reveal the critical role of FH and its succinylation in CRC cell adaptation to glucose starvation, inhibiting ferroptosis, and maintaining cancer cell proliferation, providing novel potential targets and a theoretical basis for the clinical treatment of CRC.
