Zinc finger protein 521 attenuates osteoarthritis via the histone deacetylases 4 in the nucleus.
Article in Bioengineered, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. 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
To determine whether zinc finger protein 521 (Zfp521) has a chondroprotective effect by maintaining extracellular matrix (ECM) homeostasis to attenuate osteoarthritis (OA). In chondrocytes, Zfp521 was overexpressed or silenced to detect its effects on proliferation, apoptosis, and ECM homeostasis. Adenovirus encoding Zfp521 was injected into the knee joints of anterior cruciate ligament transection rats to test its efficacy against OA. Combined with proteomic analysis, the molecular mechanism of Zfp521 in cartilage degeneration was further explored. An intra-articular injection of adenovirus carrying a Zfp521 sequence showed a chondroprotective effect against OA. The molecular mechanism around Zfp521 was classified at the molecular, cellular, histological, and functional levels. It was reported that Zfp521 could effectively promote cartilage proliferation, inhibit apoptosis, and maintain the balance of anabolism and catabolism of ECM. Moreover, it was confirmed that Zfp521 exerted its effect better by upregulating histone deacetylases 4 (HDAC4) in the nucleus and was significantly weakened in the absence of HDAC4 in the nucleus. Overall, Zfp521 better exerts its efficacy against OA by increasing the HDAC4 content in the nucleus, making it a promising strategy for OA treatment.
