Autophagy-prominent cell clusters among human lens epithelial cells: integrated single-cell RNA-sequencing analysis.
Article in BMC ophthalmology, 2023. 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
backgroundAutophagy is an important process that maintains the quality of intracellular proteins and organelles. There is extensive evidence that autophagy has an important role in the lens. Human lens epithelial cells (HLECs) play a key role in the internal homeostasis of the lens. HLEC subtypes have been identified, but autophagy-prominent cell clusters among HLECs have not been characterized. PURPOSE: To explore the existence of autophagy-prominent cell clusters in HLECs.
methodsThree donated lenses (HLECs from two whole lenses and HLECs from one lens without the anterior central 6-mm zone) were used for single-cell RNA sequencing (scRNA-seq). AUCell and AddModuleScore analysis were used to identify potential autophagy-prominent cell clusters. Transmission electron microscopy (TEM) was used to confirm the results.
resultsHigh-quality transcripts from 18,120 cells were acquired by scRNA-seq of the two intact lenses. Unsupervised clustering classified the cells into four clusters. AUCell and AddModuleScore analysis revealed cluster 1 is autophagy-prominent. scRNA-seq analysis of HLECs from the lens capsule lacking the central zone confirmed the cluster 1 HLECs was located in the central capsule zone. The TEM result showed that greater autophagy activity was observed in the HLECs in central capsule zone, which further supported the above conclusions based on scRNA-seq analysis that autophagy was prominent in the central zone where the cluster 1 HLECs located.
conclusionsWe identified an autophagy-prominent cell cluster among HLECs and revealed that it was localized in the central zone of the lens capsule. Our findings will aid investigations of autophagy in HLECs and provide insights to guide related research.
