Cancer cachexia in STK11/LKB1-mutated non-small cell lung cancer is dependent on tumor-secreted GDF15.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Cachexia is a wasting syndrome involving adipose, muscle, and body weight loss in cancer patients. Tumor loss-of-function mutations in STK11/LKB1, a regulator of AMP-activated protein kinase, induce cancer cachexia (CC) in preclinical models and are linked to weight loss in non-small cell lung cancer (NSCLC) patients. This study examines the role of the integrated stress response (ISR) cytokine growth differentiation factor 15 (GDF15) in regulating cachexia using patient-derived and engineered STK11/LKB1-mutant NSCLC lines. Tumor cell-derived serum GDF15 levels are elevated in mice bearing these tumors. Treatment with a GDF15-neutralizing antibody or silencing GDF15 from tumor cells prevents adipose/muscle loss, strength decline, and weight reduction, identifying tumors cells as the GDF15 source. Restoring wild-type STK11/LKB1 in NSCLC lines with endogenous STK11/LKB1 loss reverses the ISR and reduces GDF15 expression rescuing the cachexia phenotype. Collectively, these findings implicate tumor-derived GDF15 as a key mediator and therapeutic target in STK11/LKB1-mutant NSCLC-associated cachexia.
