Synthetic Peptides Induce Human Colorectal Cancer Cell Death via Proapoptotic Pathways.
Article in ACS omega, 2024. 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
Cancer resistance to drugs and chemotherapy is a problem faced by public health systems worldwide. Repositioning antimicrobial peptides could be an efficient strategy to overcome that problem. This study aimed at repurposing antimicrobial peptides PepGAT and PepKAA for cancer treatment. After screening against several cancers, PepGAT and PepKAA presented IC50 values of 125.42 and 40.51 μM at 72 h toward colorectal cancer (CRC) cells. The mechanisms of action revealed that both peptides induced cell cycle arrest in G2/M and drove HCT-116 cells to death by triggering apoptosis. qPCR analysis revealed that peptides modulated gene expression in apoptosis, corroborating the data from caspase 3/7 and flow cytometry experiments. Yet, peptides induced ROS overaccumulation and increased membrane permeabilization, pore formation, and loss of internal content, leading to death. Additionally, peptides were able to inhibit cell invasion. Previous studies from the same group attested to no toxicity to normal human cells. Thus, PepGAT and PepKAA have great potential as anticancer molecules.
