LRRC8A/PKC/FLNA pathway activation is detrimental to colon cancer patients.
Article in Functional & integrative genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The volume-regulated anion channel (VRAC) is implicated in remodeling the cytoskeleton. Leucine-rich repeat-containing 8A (LRRC8A) serves as a critical constituent of VRAC; however, its interaction with the scaffolding protein FLNA has not yet been clearly defined. This study demonstrated that the expression levels of the FLNA protein in colon cancer tissues exceeded those in the corresponding adjacent non-cancerous tissues, and its elevated mRNA expression was associated with an unfavorable prognosis in colon cancer patients. Transcriptomic analysis indicated that FLNA silencing altered the expression of 838 genes in HCT116 cells, primarily related to cellular motility and growth. Upon silencing FLNA in HCT116 and SW480 cells, cell migration and proliferation were markedly diminished, the cell cycle experienced a G2/M phase arrest, and apoptosis rates significantly increased. The Pearson correlation coefficient for genetic distances between FLNA and LRRC8A across various species was calculated at 0.912. At the transcription level, the correlation coefficient between LRRC8A and FLNA was determined to be 0.547, with colon cancer patients exhibiting elevated levels of both FLNA and LRRC8A mRNA showing the most adverse outcomes. Immunofluorescence analysis revealed a high Pearson's co-localization coefficient between PKC and FLNA proteins. Treatment of HCT116 cells with 20 μM DCPIB resulted in the reorganization and dispersion of aggregated FLNA proteins, coinciding with a notable reduction in the concentrations of DAG and PKC. In summary, LRRC8A modulates FLNA to influence cellular growth and migration through the DAG-PKC signaling pathway, and their combination could signify a prospective biomarker for colon cancer.
