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

The procedures described here are designed for engineering Saccharomyces cerevisiae to produce sesquiterpenes with an aim to either increase product titers or to simply generate a quantity of product sufficient for identification and/or downstream experimentation. Engineering high-level sesquiterpene production in S. cerevisiae often requires iterations of strain modifications and metabolite analysis. To address the latter, the methods described here were tailored for robust measurement of metabolites that we have found to be fundamental indicators of pathway flux, using only gas chromatography and mass spectrometry (GC-MS) instrumentation. Thus, by focusing on heterologous production of sesquiterpenes via the mevalonate (MEV) pathway in S. cerevisiae, we detail procedures for extraction and detection of the key pathway metabolites MEV, squalene and ergosterol, as well as the farnesyl pyrophosphate (FPP)-derived side products farnesol and nerolidol. Analysis of these compounds is important for quality control, because they are possible indicators of pathway imbalance. As many of the sesquiterpene synthase (STS) genes encountered in nature are of plant origin and often not optimal for expression in yeast, we provide guidelines for designing gene expression cassettes to enable expression in S. cerevisiae. As a case study for these protocols, we have selected the sesquiterpene amorphadiene, native to Artemisia annua and related plants. The analytical steps can be completed within 1-2 working days, and a typical experiment might take 1 week.
