1 · What the graph read from it

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.

2 · The registry

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

backgroundColorectal cancer (CRC) ranks among the most prevalent malignancies globally, and radiotherapy remains a critical treatment modality. However, its efficacy is frequently compromised by acquired radioresistance. The endoplasmic reticulum chaperone protein BIP plays a pivotal role in regulating radioresistance by coordinating the balance between protective autophagy and apoptosis, though the regulatory roles of circular RNAs (circRNAs) in this process remain poorly understood. MATERIALS: Differentially expressed circRAB5A (hsa-circ-0123297) was identified from the GSE186940 dataset. Its expression was validated in radioresistant CRC clinical samples and cell lines. Mechanistic investigations involved ADAR1 binding assays, circRAB5A gain/loss-of-function studies, autophagy-apoptosis profiling, ubiquitination analysis, TRIM21-mediated degradation assays, and RESULTS &

conclusionCircRAB5A was significantly downregulated in radioresistant CRC clinical samples and cell lines. This downregulation was driven by ADAR1, which suppressed circRAB5A biogenesis by binding to Alu Jo/Jr elements. Functional assays showed circRAB5A depletion conferred radioresistance in CRC cells by promoting protective autophagy and inhibiting apoptosis. Mechanistically, circRAB5A destabilized BIP by enhancing TRIM21-mediated ubiquitination. The circRAB5A/BIP axis further modulates the autophagy-apoptosis balance through the p-Akt/Beclin1 signaling pathway, thereby influencing radiosensitivity.
