Inhibition of phosphatidylserine synthesis by glutamate, acetylcholine, thapsigargin and ionophore A23187 in glioma C6 cells.

Phosphatidylserine synthesis was studied in glioma C6 cells with [14C]serine and in the presence or absence of agents which increase the level of [Ca2+]i. It was found that glutamate and acetylcholine inhibited this synthesis by up to 40%, whereas thapsigargin and the ionophore A23187 inhibited by up to 70%. The inhibitory effect of thapsigargin and the A23187 was observed in Ca(2+)-free medium. The data show that the inhibition of this synthesis is caused by the Ca(2+)-depletion from endoplasmic reticulum, suggesting that the synthesis of phosphatidylserine occurs on the luminal side of these structures and can be regulated by transmembrane signaling systems.

[The study of candidates' genes in psychiatric diseases. I. Schizophrenia].

The study concerning the importance of genetic factors in etiopathogenesis of schizophrenia is presented below. In molecular genetics research there are two most frequently applied strategies: searching of the whole genome in order to find new genes; and molecular analysis of a candidate gene. Candidate gene analysis consist in choosing a gene which could theoretically have a connection with a given certain disease. The presented reference review includes the results of study concerning candidate genes analysis referring to biochemical hypothesis of schizophrenia. The aim of the study is to find changes at the level of nucleotide sequence in DNA, which have a connection with the disease. It was stated in many medical centres that in case of schizophrenia the polymorphism of gene's receptor D3 and gene's receptor 5HT2A can be of etiological importance. It was also proved that the clinical effect of clozapine could be connected with polymorphism of gene's receptor 5HT2A.

[The study of candidate genes in psychiatric disease. II. Affective disorders].

The results of research concerning the importance of genetic factors in etiopathogenesis of affective diseases are presented. In molecular genetics research there are two most frequently applied strategies: searching of the whole genome in order to find new genes and molecular analysis of candidate genes. Candidate gene analysis consist in choosing a gene which could theoretically have a connection with the disease. The polymorphism of a chosen gene is estimated and then its connection with the disease is defined. The presented reference review concerns the results of candidate genes research, which refer to biochemical hypothesis of affective diseases. In many medical centers it was found that in affective disorders the polymorphism of gene's receptor D4, GABA and serotonin transporter could be of etiological importance.
