Interleukin 1 induces the expression of a heat-shock gene in chondrocytes.

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 presence of T cells and antibodies reactive with heat-shock proteins (hsps) in the joints of patients with rheumatoid arthritis may indicate a role of hsps in this disease. In the present study we examined whether increased temperature and interleukin 1 (IL 1), both of which are elevated in arthritic joints, induced the expression of two hsp70 genes in bovine chondrocyte cultures. We found that heat shock resulted in increased expression of constitutive and inducible hsp70 mRNA species. IL 1 and phorbol 12-myristate 13-acetate (PMA) also induced an increase in the constitutive hsp70 mRNA species, but without affecting the expression of the inducible hsp70 gene. The increase induced by IL 1 was observed only after 3 h, whereas increases induced by PMA were observed within 1 h. For all treatments, the hsp70 mRNA decreased by 24 h. Heat treatment of chondrocytes did not affect levels of collagenase and caseinase activity in the medium, nor did it alter proteoglycan synthesis by these cells.
