CLEM Characterization of Rab8 and Associated Membrane Trafficking Regulators at Primary Cilium Structures.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Correlative light and electron microscopy (CLEM) enables determination of high-resolution structural information for proteins of interest within their biological context through the combination of electron and fluorescence microscopies. Numerous electron microscopy (EM) studies of primary cilia have provided ultrastructural details about these antennal-like organelles that extend from the surface of the cell. The core structure of the cilium includes a microtubule-based axoneme, a basal body derived from the mother centriole, and the ciliary membrane, which is connected to the plasma membrane. The small GTPase Rab8 localizes to the ciliary membrane and is important for ciliogenesis, and Rab11 transports the Rab8 guanine nucleotide exchange factor (GEF) Rabin8 to the mother centriole to activate Rab8-dependent ciliary membrane growth. Some primary cilia have a ciliary pocket membrane (CPM) which is observed as an involution from the plasma membrane to the base of the cilia membrane. The Rab11- and Rab8-assocaited membrane trafficking regulator Eps15 Homology Domain-containing protein 1 (EHD1) and EHD3 also function in early stages of ciliogenesis; however, they localize to the CPM. These ciliary localizations of Rab8 and EHD1 can be resolved using CLEM with conventional fluorescence microscopy and transmission electron microscopy (TEM) imaging. Here, we describe in detail the protocol for this CLEM method applicable for ciliary proteins and proteins in other cellular organelles.
