Synapsins are the neuronal phosphoproteins which play very important role in processes of synaptic neurotransmission. They are physiological substrates for Ser/Thr protein kinases. The reversible phosphorylation of synapsins may be modified by several compounds including steroid hormones. The aim of our study was to investigate, if the one of neuroactive steroid - 17ß-estradiol - could modulate the phosphorylation of synapsins by PKA, CaM-PK and PKC in rat brain and what type of mechanism of their action is possible. The activity of kinases was evaluated as phosphorylation of synapsin in cerebral cortex and hippocampus in vivo and in vitro conditions. We conclude that 17E2 has inhibitory effect on synapsins phosphorylation by all tested kinases in vitro and in vivo conditions. The lack of nuclei in synaptosomal membrane fraction and short time of hormone exposure can be evidence of direct, non-genomic mechanism of estradiol action.

Angiotensin II (Ang II) is known to modulate tyrosine kinases (PTKs) activity in pituitary tumor cells. It is known that AngII is acting via AT1 receptors in many tissues. The aim of this study was to see whether 3-8 fragment of AngII, called angiotensin IV (AngIV) has a similar effect on tyrosine kinase activity in normal pituitary gland and what type of angiotensin receptor is involved in this process. The homogenates of normal rat pituitaries was a source of enzymes. The PTKs activity was determined using the synthetic substrate poly GluTyr and -32P-ATP. Ang IV was found to increase the PTK activity in the rat anterior pituitary tissue, with the maximal effect at concentration of 10-10M. AngII was ineffective at all concentrations studied. Losartan, a selective AT1 receptor blocker, added together with Ang IV abolished the effect of the latter, however losartan diminished also the PTK activity when applied together with Ang II, but only when it was added immediately before, but not after, the addition of Ang II. The involvement of a non-classic AT1-like receptor is suggested.
