Somatotrophs from male rat anterior pituitary were used to investigate the formation of secretory granules. When enzymatically dispersed cells were incubated with cationized ferritin (CF) for 15 min, CF labeled immature secretory granules, but not mature granules of somatotrophs. Most immature granules labeled by CF transformed to the mature types within(More)
Background—Peroxisome proliferator-activated receptors (PPARs) are transcription factors of the nuclear receptor superfamily. It has been reported that the thiazolidinediones, which are antidiabetic agents and high-affinity ligands for PPAR␥, regulate growth of vascular cells. In the present study, we examined the role of PPAR␥ in angiotensin II (Ang(More)
