Activin A suppresses interleukin-1-induced matrix metalloproteinase 3 secretion in human chondrosarcoma cells.

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
The objective was to investigate the effect of activin A on matrix metalloproteinase 3 (MMP-3) production and to identify the role of activin A in chondroprotection. SW1353 cells, a human chondrosarcoma cell line, were stimulated with interleukin (IL) 1alpha and tumor necrosis factor (TNF) alpha, and the concentrations of activin A, follistatin, and MMP-3 secreted into the culture media were measured by enzyme-linked immunosorbent assay (ELISA). Activin A was added to cell cultures in the presence of IL-1alpha or TNFalpha to determine its effect on the production of MMP-3 and sulfated glycosaminoglycan (sGAG) (measured by Alcian blue assay). To study the mechanism responsible for the chondroprotective effects of activin A, the production of IL-1 receptor antagonist (IL-1ra) and tissue inhibitor for metalloproteinases 1 (TIMP-1) was examined by ELISA. Addition of IL-1alpha did not affect the production of activin A by cultured SW1353 cells. IL-1alpha and activin A inhibited the production of follistatin. Stimulation of SW1353 cells with activin A suppressed IL-1alpha-induced, but not TNFalpha-induced, MMP-3 expression. Activin A had no effect on the production of sGAG, IL-1ra, or TIMP-1, although it suppressed the induction of TIMP-1 and IL-1ra by IL-1alpha. This novel finding of MMP-3 inhibition by activin A suggests a new role of activin A in cartilage remodeling. Activin A may have therapeutic potential for preventing cartilage degradation.
