Circulating insulin levels in B6 mice treated with letrozole
Summary Data Summary
Investigator Thackray, Varykina
Description Letrozole treatment of pubertal female mice results in hallmarks of PCOS
including elevated androgens, anovulation, polycystic ovaries and a metabolic

Puberal (4 week old) female mice were implanted with a placebo or letrozole
pellet (50 ug/day) and treated for 5 weeks. The antibiotics were administered
via mixing it into their drinking water. The antibiotic water was made via the
dosage of 1g/L of Ampicilin, 0.5g/L of Vancomycin, and 1g/L of Neomycin. Mice
had ad lib access to food and water. Mice were sacrificed with isoflurance and
blood was collected via the vena cava and spun down to collect serum.
