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

Background: Chemoresistance, the primary cause of disease relapse and treatment failure, poses a significant challenge in the treatment of colorectal cancer (CRC). Understanding the molecular mechanisms that underlie the pathogenesis and chemoresistance of colorectal tumor cells, as well as identifying novel therapeutic strategies, would be crucial. This study aimed to evaluate the role of hsa_Circ_0001821 in response to 5-fluorouracil (5-FU) in CRC, a topic that has not been examined to date. Methods: The current study investigated the effect of hsa_Circ_0001821 suppression using interfering RNAs on the response of colorectal tumor cells to 5-FU. The expression levels of hsa_Circ_0001821, hsa-miR-203a-3p, BAX, BCL-2, and FGF-2 were determined via quantitative RT-PCR. Cell survival, migration rate, and apoptosis induction of colorectal tumor cells subjected to 5-FU treatment were assessed using the MTT test, scratch assay, and flow cytometry analysis, respectively. Results: Knockdown of hsa_Circ_0001821 with siRNA increased the expression level of hsa-miR-203a-3p and decreased the expression level of FGF-2. Additionally, the knockdown of hsa_Circ_0001821 enhanced the sensitivity of colorectal tumor cells to 5-FU. This circRNA significantly affected the viability, apoptosis, and migration of tumor cells. Conclusion: Our study reveals the potential role of hsa_Circ_0001821 in controlling the tumor cell viability and response to 5-FU by targeting the hsa-miR-203a-3p/FGF-2 axis. These findings enhance our understanding of the molecular mechanisms that influence chemotherapy response in CRC, paving the way for the identification of more effective treatments for this disease.
