Chronic interleukin-6 (IL-6) treatment increased IL-6 secretion and induced insulin resistance in adipocyte: prevention by rosiglitazone
Abstract
IL-6 has emerged as an important cytokine upregulated in states of insulin resistance such as type 2 diabetes. We evaluated the chronic effect of IL-6 on insulin signaling in 3T3-F442A and 3T3-L1 adipocytes. First, cells responded to a chronic treatment with IL-6 by initiating an autoactivation process that increased IL-6 secretion. Second, IL-6-treated adipocytes showed a decreased protein expression of IR-beta subunit and IRS-1 but also an inhibition of the insulin-induced activation of IR-beta, Akt/PKB, and ERK1/2. Moreover, IL-6 suppressed the insulin-induced lipogenesis and glucose transport consistent with a diminished expression of GLUT4. IL-6-treated adipocytes failed to maintain their adipocyte phenotype as shown by the downregulation of the adipogenic markers FAS, GAPDH, aP2, PPAR-gamma, and C/EBP-alpha. IL-6 also induced the expression of SOCS-3, a potential inhibitor of insulin signaling. Finally, the effects of IL-6 could be prevented by rosiglitazone, an insulin-sensitizing agent. Thus, IL-6 may play an important role in the set-up of insulin resistance in adipose cell.

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.
