Advances in the basic function of the small GTPase SAR1B and its regulatory role in the biological behavior of tumor cells (Review).
Review in Molecular and clinical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 secretion associated Ras related GTPase 1B (SAR1B) is a member of the ADP-ribosylation factor (Arf) subfamily of small GTPases. It participates in various physiological activities, such as protein transport, lipid metabolism and stress response of cells by regulating the formation of coat protein complex II (COPII) vesicles. Moreover, SAR1B is an important link in the transduction of tumor cell signaling pathways [for example, mechanistic target of rapamycin kinase (mTOR), Wnt/β-catenin]. In the present article, the structure and basic function of SAR1B, as well as the research progress of SAR1B in tumor cell substance transport and metabolism, stress autophagy regulation and tumor signaling pathway, were reviewed. In addition, approaches to rationally utilizing the different functions of SAR1B in different physiological and pathological environments to achieve effective inhibition of tumor cell growth, proliferation and migration, were discussed. Furthermore, a theoretical basis for the use of SAR1B as a new target for tumor therapy was provided.
