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

Endolysosomes are dynamic organelles that undergo movement along the cytoskeleton, fusion, fission, and tubulation during their lifetime. These processes are regulated by complex molecular machineries, including the structurally related hetero-octameric complexes BLOC-1 and BORC. BLOC-1 associates with early endosomes to mediate the biogenesis of lysosome-related organelles (LROs), such as melanosomes and platelet dense bodies. Accordingly, mutations in BLOC-1 subunits cause Hermansky-Pudlak syndrome (HPS), a disorder characterized by pigmentation defects and bleeding abnormalities. In contrast, BORC associates with lysosomes, late endosomes, and synaptic vesicle precursors, promoting their transport along microtubules. BORC also regulates endolysosome fusion with other endolysosomes, as well as with phagosomes and autophagosomes. Mutations in BORC subunits cause a severe neurodevelopmental disorder in humans. In this article, we review recent progress in the elucidation of the structure, evolution, physiological roles, and regulation of BLOC-1 and BORC, highlighting their critical contributions to maintaining endolysosomal organization and function.
