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

Kluyveromyces marxianus is a fast-growing, food-grade yeast with broad substrate utilization, however, its limited expression tools hinder its synthetic biology applications. Here, we developed single- and dual-gene expression systems based on screened elements, including a promoter pENO and a bidirectional promoter pHTX. These systems enabled stable expression across multiple K. marxianus strains, with expression levels affected by genetic element combinations, carbon source, and culture time. Using the single-gene system with a short intergenic sequence (IGG) for bicistronic expression, the production of leghemoglobin from Vigna angularis (VaHB) reached 30.4 mg/L using galactose as carbon source. In contrast, the dual-gene system achieved 48.4 mg/L of VaHB with the co-expression of HEM1, enhancing heme biosynthesis using glucose as a carbon source. Additionally, Simian Virus 40 (SV40) nuclear localization signals (NLS) directed fluorescent proteins to the nucleus, enabling subcellular targeting. This toolkit supports efficient and context-responsive gene expression in K. marxianus, facilitating its development as a versatile microbial chassis for industrial protein production and synthetic biology applications.
