Estradiol stimulation of c-fos and c-jun expressions and activator protein-1 deoxyribonucleic acid binding activity in rat white adipocyte.

abstract：:Obesity is often associated with an impairment of the hypothalamic-pituitary-gonadal axis. The leptin-deficient ob/ob mouse model is characterized by a morbid obesity with a sterility in males and females that is corrected by continuous leptin treatment. Since ob/ob mice are maintained on the C57BL/6J inbred genetic b...
