Abstract

Mesangial cells play an active role in the inflammatory response to glomerular injury. We have studied in cultured human mesangial cells (CHMC) several effects of 9‐cis retinoic acid (9‐cRA), an activator of both retinoic acid receptors (RARs) and retinoid X receptors (RXRs). 9‐cRA inhibited foetal calf serum‐induced CHMC proliferation. It also prevented CHMC death induced by the inflammatory mediator H 2 O 2. This preventive effect was not due to any increase in H 2 O 2 catabolism and it persisted even when both catalase and glutathione synthesis were inhibited. Finally, 9‐cRA diminished monocyte adhesion to FCS‐stimulated CHMC. Interestingly, the retinoid also inhibited in FCS‐stimulated cells the protein expression of two mesangial adhesion molecules, fibronectin and osteopontin, but it did not modify the protein expression of intercellular adhesion molecule‐1 and vascular adhesion molecule‐1. All major RARs and RXRs isotypes were expressed in CHMC regardless of the presence or absence of 9‐cRA. Transcripts to RAR‐α, RAR‐β and RXR‐α increased after incubation with 9‐cRA whereas RXR‐γ was inhibited, suggesting a major role for RARs and RXRs in 9‐cRA‐anti‐inflammatory effects. 9‐cRA was toxic only at 50 μ M (a concentration 50–5000 times higher than required for the effects above). Cell death occurred by apoptosis, whose onset was associated with a pronounced increase in catalase activity and reduced glutathione content, being more effectively induced by all‐trans retinoic acid. Modulation of the oxidant/antioxidant balance failed to inhibit apoptosis. We conclude that mesangial cells might be a target for the treatment of inflammatory glomerulopathies with 9‐cRA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
