Dissociation of serum triiodothyronine concentration and hepatic nuclear triiodothyronine-binding capacity in streptozotocin-induced diabetic rats.

abstract：:As we showed previously, the extracellular matrix (ECM) derived from rat bladder carcinoma cells (804G-ECM) has positive effects on rat primary beta-cell function and survival in vitro. The aim of this study was to define beta-cell genes induced by this ECM with a specific focus on cytokines. Analysis of differential ...
