General description

Thyroxine or T4 is a thyroid hormone responsible for regulation of the body′s basal metabolic rate and essential for growth, development and heart and nervous system function. Free and total T4 serum levels are measured by LC-MS/MS for determination of hyper- or hypothyroidism as well as for monitoring treatment with synthetic thyroid hormones. This Certified Spiking Solution® is suitable for use in LC-MS/MS testing methods as starting materials in preparation of linearity standards, calibrators, and controls.

Biochem/physiol Actions

La L-tiroxina (T4) y la triyodo-L-tironina (T3) son hormonas que contienen yodo producidas a partir de la tiroglobulina en las células foliculares tiroideas. La estimulación de la tasa metabólica y la regulación del crecimiento y el desarrollo por esas hormonas parece deberse a sus efectos sobre la transcripción del ADN y, por tanto, la síntesis de proteínas.

Neonatal screening programs for congenital hypothyroidism (CH) were initiated in the 1970s to ensure early treatment in order to prevent mental retardation. With screening, developmental prognosis is considerably improved, but follow-up studies still report developmental delay compared to controls. To

Human ATRX mutations are associated with cognitive deficits, developmental abnormalities, and cancer. We show that the Atrx-null embryonic mouse brain accumulates replicative damage at telomeres and pericentromeric heterochromatin, which is exacerbated by loss of p53 and linked to ATM activation.

Thyroid hormone is crucial for brain development during foetal and neonatal life. In very preterm infants, transient low levels of plasma T4 and T3 are commonly found, a phenomenon referred to as transient hypothyroxinaemia of prematurity. We investigated whether breast
