Inhibition of Phlpp1 preserves the mechanical integrity of articular cartilage in a murine model of post-traumatic osteoarthritis.
Article in Osteoarthritis and cartilage, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectivePhlpp1 inhibition is a potential therapeutic strategy for cartilage regeneration and prevention of post-traumatic osteoarthritis (PTOA). To understand how Phlpp1 loss affects cartilage structure, cartilage elastic modulus was measured with atomic force microscopy (AFM) in male and female mice after injury.
methodsOsteoarthritis was induced in male and female Wildtype (WT) and Phlpp1
resultsMale WT mice showed decreased activity and histological signs of cartilage damage at 12 but not 6-weeks post-DMM. Female mice showed a less severe response to DMM by comparison, with no histological changes seen at any time point. In both sexes the elastic modulus of medial condylar cartilage was decreased in WT mice but not Phlpp1
conclusionsAFM is a sensitive method for detecting early changes in articular cartilage post-injury. Phlpp1 suppression, either through genetic deletion or pharmacological inhibition, protects cartilage degradation in a model of PTOA, validating Phlpp1 as a therapeutic target for PTOA.
