The effects of alpha-MSH and cAMP on melanosomes in Cloudman S91 melanoma cells were investigated by modern stereological techniques. Cells were cultured for 4 days in medium containing alpha-MSH or cAMP, harvested at 24 hour intervals; some were fro

Hair follicle tyrosinase levels and melanin content, together with serum tyrosine levels have been studied in relation to annual pelage color changes in the Siberian hamster. Tyrosinase levels were found to peak not only at the spring moult when pigm

In short-term (48 hr) culture hair follicles of the Siberian hamster retain both tyrosinase activity and the capacity to produce melanin. The addition of melatonin to such cultures at concentrations between 10 −6 M and 10 −10 M brings about a dos

Melanotrophin-potentiating factor (MPF) is a fragment of human beta-lipotrophin (LPH 88-91) which potentiates the action of alpha-MSH on Anolis skin. In the present study, we investigated the effect of MPF on MSH-induced melanogenesis. Pooled hair fo

It has been confirmed that intracisternal administration of the sympatholytic compound 6-hydroxydopamine (6-OHDA) to the toad Xenopus brings about degenerative changes in the appearance of the catecholaminergic innervation of the pars intermedia of t

α-Melanocyte-stimulating hormone (α-MSH) has been shown to act directly on the mammalian melanocyte in short-term cultures of hair follicles obtained from the Siberian hamster. Melanogenesis was stimulated through an increase in tyrosinase activity

A stereological analysis has been made of the daily changes occurring in the ultrastructure of the melanotrophs of the pars intermedia of the pituitary gland of the Djungarian or Siberian hamster, Phodopus sungorus, maintained in long day photoperiod

The nature of the small electron-lucent vesicles present in neurosecretory neurons have been the subject of controversy for many years. Some authors have suggested that they may be synaptic vesicles containing acetylcholine since they resemble in siz
