1 · What the graph read from it

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.

2 · The registry

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

backgroundTripartite motif-containing 27 (TRIM27) is highly expressed in the mouse thymus, spleen, and hematopoietic compartment cells and regulates cell proliferation, apoptosis, and innate immune responses. However, the role of TRIM27 in bone remodeling remains unknown. This study aimed to investigate the role of TRIM27 in the differentiation of osteoclasts and osteoblasts.

methodsWe measured the effects of overexpression or knockdown of TRIM27 in osteoclasts and osteoblasts using real-time PCR and Western blot analysis to quantify the mRNA and protein levels of marker genes. Additionally, we performed an in vivo analysis of TRIM27 knockout mice through bone mineral density analysis and histological analysis.

resultsTRIM27 deficiency decreased bone mineral density by enhancing osteoclast differentiation and inhibiting osteoblast differentiation. Overexpression of TRIM27 in osteoclast precursors suppressed osteoclast formation and resorption activity, and ectopic expression of TRIM27 in osteoblast precursors induced osteoblast differentiation and mineralization. Additionally, we found that TRIM27 attenuated NF-κB activation in both osteoclasts and osteoblasts by interacting with TAB2 and promoting TAB2 degradation through lysosomal-dependent pathways, thereby inhibiting NF-κB signaling.

conclusionsOur results identify TRIM27 as a novel negative regulator of NF-κB in bone remodeling, suggesting that regulating TRIM27 may be useful in developing treatments for musculoskeletal diseases, such as osteoporosis.
