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

Background: Exposure to cigarette smoke (CS) is the main risk factor for chronic obstructive pulmonary disease (COPD). CS not only causes chronic airway inflammation and lung damage but also is involved in skeletal muscle dysfunction (SMD). Previous studies have shown that histone deacetylase 2 (HDAC2) plays an important role in the progression of COPD. The aim of this study was to determine the role of HDAC2 in CS-induced skeletal muscle atrophy and senescence. Methods: Gastrocnemius muscle weight and cross-sectional area (CSA) were measured in mice with CS-induced emphysema, and changes in the expression of atrophy-related markers and senescence-related markers were detected. In addition, the relationship between HDAC2 expression and skeletal muscle atrophy and senescence was also investigated. Results: Mice exposed to CS for 24 weeks developed emphysema and gastrocnemius atrophy and exhibited a decrease in gastrocnemius weight and skeletal muscle cross-sectional area. In addition, the HDAC2 protein levels were significantly decreased while the levels of atrophy-associated markers, including MURF1 and MAFbx, and senescence-associated markers, including P53 and P21, were significantly increased in the gastrocnemius muscle. In vitro, the exposure of C2C12 cells to cigarette smoke extract (CSE) significantly increased the MAFbx and MURF1 protein levels and decreased the HDAC2 protein levels. Moreover, overexpression of HDAC2 significantly ameliorated CSE-induced atrophy and senescence and reversed the increased MURF1, MAFbx, P53, and P21 expression in C2C12 cells. In addition, CSE treatment significantly increased the IKK and NF-κB p65 protein levels, and PTDC (an NF-kB inhibitor) ameliorated atrophy and senescence. Conclusion: Our findings suggest that HDAC2 plays an important role in CS-induced skeletal muscle atrophy and senescence, possibly through the NF-κB pathway.
