The effects of WWP1 overexpression on the golgi apparatus stress response and proteoglycan production in adipocytes.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
White adipocytes are a major component of white adipose tissue (WAT) and help to maintain systemic metabolic homeostasis by storing energy and secreting adipokines. In mice deficient in the protein WWP1 (WW domain-containing E3 ubiquitin protein ligase 1), oxidative stress in adipocytes increases but insulin resistance induced by obesity improves. However, the specific roles of WWP1 in adipocytes remain unclear. Here, we show that in 3T3L1 adipocytes, WWP1 localized in the Golgi apparatus via its C2 domain, where it protected the Golgi apparatus from monensin-induced disruption. By contrast, WWP1 knockdown by short hairpin RNA failed to protect the Golgi apparatus and enhanced Golgi apparatus disruption by monensin. The Golgi apparatus acts as a central organelle to establish accurate protein glycosylation of proteoglycans containing glycosaminoglycans, including chondroitin sulfate and heparan sulfate (HS). WWP1 overexpression increased chondroitin sulfate and HS levels, whereas WWP1 knockdown decreased them. Furthermore, obesity-related increases in HS were prevented by WWP1 knockout in adipose tissue. In summary, our results demonstrate a novel role for WWP1 in maintaining Golgi apparatus morphology and proteoglycan synthesis in adipocytes.
