Reduction-oxidation reactions and regulatory proteins, such as thioredoxin (TRX) and thioredoxin reductase (TRXR), are intimately involved in the regulation of oxidative stress. The aim of this study was to determine the levels of TRX mRNA and protein in ovarian follicles collected from women undergoing in vitro fertilization (IVF) and to assess these levels relative to follicle size, presence of oocytes, and responsiveness to superovulation.

Defects in insulin receptor function have been associated with insulin resistant states such as obesity and type 2 diabetes mellitus. Several types of mutations in the insulin receptor gene have been identified in patients with genetic syndromes of extreme insulin resistance. We have studied a 10-year-old Japanese girl with type A insulin resistance with hirsutism and hyperinsulinemia but without the dysmorphic features characteristic of leprechaunism or Rabson-Mendenhall syndrome.
