The circRNA circSCAF8 promotes tumor growth and metastasis of gastric cancer via miR-1293/TIMP1signaling.
Article in Gene therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
SR-like CTD-associated factor 8 (SCAF8) can regulate transcriptional termination, but the function of circSCAF8 remains unclear. In our study, we observed a significant increase in circSCAF8 expression in gastric cancer, particularly in tissues with lymph node metastasis. The Kaplan-Meier curve revealed that high circSCAF8 expression was associated with a low overall survival time in gastric cancer patients. Moreover, circSCAF8 shRNA effectively decreased gastric cancer proliferation, invasion, and migration in vitro. Additionally, using bioluminescence imaging (BLI) technology in vivo, we found that circSCAF8 shRNA viruses inhibited the growth of xenograft tumors and gastric cancer lung metastasis. RNA immunoprecipitation (RIP) and circRNA pulldown assays confirmed the direct binding of circSCAF8 to miR-1293, but circSCAF8 could not regulate the expression of miR-1293 in gastric cancer. Interestingly, circSCAF8 regulated the downstream gene tissue inhibitor of metalloproteinases 1 (TIMP1) of miR-1293, and this observation was further verified in gastric cancer tissues. Moreover, we confirmed that miR-1293 directly suppressed TIMP1 expression. Subsequent rescue experiments revealed that TIMP1 overexpression reversed the impact of circSCAF8 shRNA viruses on gastric cancer. In conclusion, circSCAF8 expression was elevated in gastric cancer, and circSCAF8 shRNA viruses inhibited gastric cancer growth and metastasis by upregulating TIMP1 expression via miR-1293.
