Free thyroxine and TSH interact with secreted protein acidic and rich in cysteine-like 1 in ischemic stroke

As thyroid hormones modulate the extracellular matrix, we explored the possible link between them and secreted protein acidic and rich in cysteine like 1 (SC1) – one of the extracellular matrix molecules. In the 81 patients with acute ischemic stroke, serum SC1 levels were much higher compared with 30 control subjects: 4.47 vs 2.43ng/mL (p <0.001). Serum levels of free thyroxine (fT4) were higher in stroke subjects compared to those of controls (p =0.03). In stroke patients, TSH concentration was lower than in the control group (p =0.03). SC1 levels positively correlated with fT4 levels (p =0.02) and negatively with TSH (p =0.03) in stroke patients. Our results confirmed the association between thyroid hormones and SC1 – extracellular matrix protein.
