Osteoarthritis rat serum-derived extracellular vesicles aggravate osteoarthritis development by inducing NLRP3-mediated pyroptotic cell death and cellular inflammation.

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
Osteoarthritis (OA), degenerative joint disease, is the most prevalent form of arthritis worldwide. Besides its substantial burden on society, the high OA morbidity greatly diminishes patients' quality of life. According to recent research, patients-derived serum extracellular vesicles (EVs) are critically involved in sustaining the corresponding disease progression. However, limited research has fully explored the specific functions and molecular mechanisms of OA serum-derived EVs in disease progression. Consequently, we aimed to investigate the underlying mechanism of OA rats-derived serum EVs in regulating OA progression. Before constructing the exosome-cell co-culture system, EVs were extracted from OA and control rat serum and co-cultured with bone marrow mesenchymal stem cells (BM-MSCs). Western blotting (WB), RT-qPCR, and enzyme-linked immunosorbent assay (ELISA) results revealed that OA rat serum-derived EVs upregulated cell pyroptosis-related markers, including nod-Like receptor protein-3 (NLRP3), apoptosis-associated speck-like protein (ASC), gasdermin D (GSDMD), and cleaved caspase-1. The OA rat-EVs also induced the release of LDH and inflammatory cytokines, including interleukin (IL)-1β, IL-18, IL-6, and TNF-α. Additional experiments revealed that OA rat-EVs delivered miR-133a-3p to BM-MSCs and upregulated miR-133a-3p to degrade sirtuin 1 (SIRT1), and activating the downstream NF-κB signaling pathway. Furthermore, the rescuing experiments confirmed that silencing SIRT1 abrogated the miR-133a-3p-induced protective effects in OA-EVs-treated BM-MSCs. In conclusion, OA rats-derived miR-133a-3p-containing EVs modulated the downstream SIRT1/NF-κB pathway-mediated pyroptotic cell death and inflammation in OA. In other words, this study confirmed the role and underlying mechanisms by which OA-associated serum EVs regulate pyroptosis and inflammation response in OA development.
