Progranulin Protects Against Osteoporosis by Regulating Osteoclast and Osteoblast Balance via TNFR Pathway.
Article in Journal of cellular and molecular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Osteoporosis is a disease of bone metabolism caused by an imbalance between osteoclast-mediated bone destruction and osteoblast-mediated bone formation. Tumour necrosis factor α (TNFα) has been reported to promote osteoclast generation and inhibit osteoblast generation. Progranulin (PGRN), which has a strong anti-inflammatory effect, interacts with tumour necrosis factor receptor (TNFR). Serum and bone tissues from patients with or without osteoporosis were collected to analyse the relationship between PGRN content and bone metabolic markers. The role of TNFα and PGRN in osteoclast differentiation was explored by using RAW 264.7 cells and BMMs. MC3T3-E1 cells and BMSCs were used to observe the role of TNFα and PGRN in osteoblast differentiation. The PGRN content in the serum and bone tissues of osteoporosis patients was lower than that in the serum and bone tissues of nonosteoporosis patients. TNFα promoted osteoclast differentiation, while PGRN inhibited this effect by interacting with TNFR1. PGRN inhibited TNFα-mediated attenuation of osteoblast differentiation by interacting with TNFR1. Moreover, PGRN alone promoted osteoblast differentiation by interacting with TNFR2. Our findings reveal that PGRN can effectively inhibit TNFα-induced osteoporosis and has a certain osteogenic effect. This discovery might provide a potential target for osteoporosis treatment.
