ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Glutamine metabolism is crucial for sustaining tumor cell viability and growth, broadly promoting prospects for the therapeutic targeting of glutamine dependence. However, further research is needed to address key translational issues, particularly to better understand the adaptive survival responses employed by cancer cells in overcoming nutrient deficiency. Long-chain acyl-CoA synthetase 5 (ACSL5) is found to be upregulated under glutamine deprivation, acting to sustain tumor cell viability by enhancing both glycolytic flux and oxidative phosphorylation. ACSL5 operates within a p53 regulatory loop: p53 transcriptionally upregulates ACSL5, while ACSL5 competes with MIB1 to stabilize MDM2, suppressing p53 expression. Mechanistically, ACSL5 relieves p53-mediated inhibition of PGAM1 to drive glycolysis, while its mitochondrial localization promotes IDH2 activation to accelerate the TCA cycle. Nonetheless, these metabolic increases also generate reactive oxygen species (ROS), inducing DNA damage and significantly enhancing colorectal cancer cell sensitivity to oxaliplatin. The latter provides an explanation as to why colorectal tumors with high ACSL5 expression display preferentially improved patient outcomes from chemotherapy. Collectively, the findings reveal a new pathway for non-genetic chemotherapy resistance mechanisms, deepen the understanding of metabolic reprogramming in tumor cells, and offer potential therapeutic targets for future treatment strategies.
