1995), the caudal and cephalic lobes can be distinguished respectively, and also LH and FSH gonadotropes
Lack of age appropriate pubertal signs in two boys can be explained on the basis of direct suppressive effect of cortisol on pituitary gonadotropes
and testis as well.
Initially, the decrease may be due to depletion of releasable pools of FSH in pituitary gonadotropes
SP22 was not observed in large gonadotropes
Exposure to B[alpha]P resulted in significant increases in serum LH levels (Figure 7A) and LH proteins (~ 20 kDa) in pituitary gland extracts (Figure 7B) and in the intensity of LH immunoreactivity in the gonadotropes
in the anterior pituitary glands (Figure 7C).
Ultrastructural characteristics of two distinct gonadotropes
, GTH I- and GTH II-cells in the pituitary of rainbow trout, Oncorhynchus mykiss.
Leptin increases L-type Ca2+ channel expression and GnRH-stimulated LH release in L[beta]T2 gonadotropes
Follicle-stimulating hormone (FSH) is a member of the glycoprotein hormones synthesized and secreted by gonadotropes
in the anterior pituitary gland and is comprised of two dissimilar subunits, alpha and beta, encoded by separate genes (Jameson et al.
It acts on gonadotropes
to stimulate synthesis and release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (Pawson and McNeilly 2005).
The objective of the present study was to determine whether exposure of pregnant sheep to environmental concentrations of a mixture of EDCs, via sewage sludge used as a fertilizer, disrupts the kisspeptin/GPR54 system, as determined by examination of KiSS-1, GPR54, and ER[alpha] (estrogen receptor-[alpha]) mRNA expression in the adult and fetal hypothalamus and pituitary and the proportions of kisspeptin positive LH-secretory gonadotropes
and estradiol-receptive gonadotropes
within the fetal pituitary gland.
Signal transduction mechanisms mediating secretion in goldfish gonadotropes
Many degenerating and nondegenerated gonadotropes
, somatotropes, and lactotropes showed dilated ER (Figures 3 and 5) and hypertrophic Golgi areas, occasionally with some lightly dense granules inside.
