The Lipid Droplet Knowledge Portal: A resource for systematic analyses of lipid droplet biology
Open accessPublished version of a preprint
Abstract
Lipid droplets (LDs) are organelles of cellular lipid storage with fundamental roles in energy metabolism and cell membrane homeostasis. There has been an explosion of research into the biology of LDs, in part due to their relevance in diseases of lipid storage, such as atherosclerosis, obesity, type 2 diabetes, and hepatic steatosis. Consequently, there is an increasing need for a resource that combines datasets from systematic analyses of LD biology. Here, we integrate high-confidence, systematically generated human, mouse, and fly data from studies on LDs in the framework of an online platform named the "Lipid Droplet Knowledge Portal" (https://lipiddroplet.org/). This scalable and interactive portal includes comprehensive datasets, across a variety of cell types, for LD biology, including transcriptional profiles of induced lipid storage, organellar proteomics, genome-wide screen phenotypes, and ties to human genetics. This resource is a powerful platform that can be utilized to identify determinants of lipid storage.

Genetic knockdown studies show RUFY2 influences lipid droplet morphology and distribution.
“Genetic knockdown studies show RUFY2 influences lipid droplet morphology and distribution9,41, hinting at a potential link between vesicle trafficking defects69 and altered lipid biology in astrocytes, particularly in neurodegenerative contexts.”
From APOE genotypes differentially remodel the astrocytic lipid droplet proteome to shape lipid droplet dynamics (2026) · cites this paper as [41]
The Results section describes lipid-droplet size, shape, and dispersion measurements after gene knockdown, but the specific knockdown result it reports concerns C16orf54, not RUFY2. Searches for “RUFY2” and “RUFY2 knockdown lipid droplet morphology distribution” found no passage in our copy linking RUFY2 to those phenotypes. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
