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

Extracellular matrix (ECM) creates the tissue microenvironment and serves a role in airway wall remodeling in chronic obstructive pulmonary disease (COPD). However, the biological function of ECM in COPD remains to be elucidated. In the present study, 24 healthy Sprague Dawley rats were randomized to normal and COPD groups. COPD was established by intratracheal injection with lipopolysaccharide over 30 days. Subsequently, airway smooth muscle cells (ASMCs) were isolated from rats and served as a model to assess the effects of three ECM components, including collagen type I, laminin and collagen type III (COL‑3). Functional analysis in vitro, using cell counting kit‑8, flow cytometry, wound healing and cell adhesion assays indicated that the ECM components could promote cell proliferation, cell cycle progression, migration and adhesion ability, respectively. Furthermore, as demonstrated by ELISA, treatment with ECM components increased levels of C‑X‑C motif chemokine ligand 1 (CXCL1), CXCL8 and interleukin‑6 in ASMCs. Expression of transforming growth factor β1 (TGFβ1), fibroblast growth factor‑1 (FGF‑1) and tissue inhibitor of metalloproteinase 1 (TIMP1) was increased, and expression of matrix metalloproteinase‑9 (MMP‑9) was decreased following treatment with ECM components, as demonstrated by reverse transcription‑quantitative polymerase chain reaction and western blot analysis. Additionally, specific activation of phosphoinositide 3‑kinase (PI3K) signaling, using insulin‑like growth factor‑1 (IGF‑1), promoted cell proliferation and cell cycle progression, increased expression of TGFβ1, FGF‑1, PI3K, AKT, phospho‑AKT, serine/threonine‑protein kinase mTOR (mTOR), phospho‑mTOR and TIMP1, promoted cell migration capacity and reduced the expression level of MMP‑9 in cells from COPD rats. Consistently, PI3K inhibitor LY294002 exerted the opposite effect to IGF‑1. In conclusion, ECM proteins promoted proliferation, migration and adhesion of ASMCs form rat models of COPD through activation of the PI3K/AKT signaling pathway.
