LncRNA CRCMSL interferes in phospholipid unsaturation to suppress colorectal cancer progression via reducing membrane fluidity.
Article in Journal of advanced research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
introductionReprogrammed metabolism is an important basis of colorectal cancer (CRC) progression; however, its mechanisms remain unclear. This study illustrated a novel mechanism for long noncoding RNA (lncRNA) CRCMSL in CRC, which was identified as a CRC suppressor in our previous study.
objectiveTo investigate whether CRCMSL suppresses colorectal cancer by interfering in lipid metabolism.
methodsPotential functions of CRCMSL were predicted by GSEA, which led to lipidomics. Ferroptosis process in CRC were evaluated by protein markers, probe-reported lipid peroxidation signals and transmission electron microscopy. Order and fluidity of phospholipid bilayers were detected by Laurdan generalized polarization (GP) assays and fluorescence recovery after photobleaching (FRAP) assays, respectively. RNA pull-down and RIP assays were performed to explore the target of CRCMSL. qPCR, western blot and enzyme activity detections were used to explore the effects of CRCMSL on the target. Orthotopic and subcutaneous xenografts in nude mice were used to validate efficacy of CRC in vivo.
resultsCRCMSL-knockdown upregulated lipid synthesis and remodeled fatty acyl chains in phospholipids, inspiring studies on ferroptosis and phospholipid bilayers. CRCMSL-mediated biological processes and behaviors were restored by stearoyl-CoA desaturase (SCD), a key enzyme for the synthesis of monounsaturated fatty acids (MUFAs), suggesting that CRCMSL promotes ferroptosis and reduces membrane fluidity by interfering in phospholipid unsaturation. The target of CRCMSL in fatty acid metabolism is acetyl-CoA carboxylase 1 (ACC1), a key enzyme for de novo fatty acid synthesis. CRCMSL promoted ACC1 phosphorylation to restrict its activity. Firsocostat, an ACC oral inhibitor ND630, is a potential drug for CRC treatment in combination with CRCMSL.
conclusionOur study illustrated a novel mechanism of CRCMSL-ACC1 axis-associated fatty acid metabolism in CRC progression, providing laboratory evidence for the development of targeted therapies for patients with advanced CRC.
