| In vivo | Propylthiouracil-induced hypothyroidism reduces oxidative damage in the lung, hepatic, renal and ileal tissues probably due to hypometabolism in rats, which is associated with decreased production of reactive oxygen metabolites and enhancement of antioxidant mechanisms. [1] Propylthiouracil-induced congenital hypothyroidism upregulates vimentin phosphorylation and depletes antioxidant defenses in immature rat testis. [2] Propylthiouracil results in lesser concentrations of thyroxine (T4) and triiodothyronine (T3), greater concentrations of follicle stimulating hormone (FSH) and luteinizing hormone (LH) peptides, and increase in steroidogenic gene expression after 12 hours and 48 hours in zebrafish. [3]Propylthiouracil-induced hypothyroidism is associated with increased tolerance of the isolated rat heart toischaemia-reperfusion. [4] Propylthiouracil (PTU) dramatically reduces thyroid hormones on PND21 and produced deficits in body weight that persisted to adulthood in developing rats. [5] Propylthiouracil inhibits both the synthesis of thyroid hormones in the thyroid gland and the conversion of T4 to its active form, T3. Propylthiouracil treatment significantly increases circulating TSH at both P3 and P7. Propylthiouracil exposure of adult rats, at a dose inducing modest reductions in circulating T4 concentrations and no significant effect on brain BDNF, significantly alteres the thyroid hormones and hippocampal BDNF levels in the offspring at 3 and 7 d after birth.

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
