Etiology of ovarian failure in blepharophimosis ptosis epicanthus inversus syndrome: FOXL2 is a conserved, early-acting gene in vertebrate ovarian development.

abstract：:We have recently disclosed sustained episodes of LH release (minisurges) during the afternoons of the juvenile-peripubertal transition period in the female rat. To determine if these LH minisurges are gonad independent, i.e. develop in the absence of the ovaries, animals were ovariectomized when neonates, and the mode...

Saturation binding of estradiol is demonstrable, with an affinity similar to that of the cytosol estrogen receptor (Ka = 1-2 X 10(10) M-1). Dissociation rate kinetic determinations, however, revealed that estrog...
