BK channels are S-acylated (palmitoylated) at two distinct sites within the N- and C-terminus of the pore-forming a-subunit. Palmitoylation of the N-terminus controls channel trafficking and surface expression whereas JQ-EZ-05 price palmitoylation of the C-terminal domain determines regulation of channel activity by AGC-family protein
kinases. Recent studies are beginning to reveal mechanistic insights into how palmitoylation controls channel trafficking and cross-talk with phosphorylation-dependent signalling pathways. Intriguingly, each site of palmitoylation is regulated by distinct zDHHCs (palmitoyl acyltransferases) and APTs (acyl thioesterases). This supports that different mechanisms may control substrate specificity by zDHHCs and APTs even within the same target protein. As palmitoylation is dynamically regulated, this fundamental post-translational modification represents an important determinant of BK channel physiology in health and disease.”

during pregnancy and lactation. SSRIs are thought to be much safer than tricyclic antidepressants, with a low risk of embryonic toxicity. Several recent studies, however, have reported that fetal exposure to SSRIs increases the risk of adverse effects during fetal and neonatal development. This is consistent with our previous finding that fluoxetine, a prototypical SSRI, profoundly affected the viability of cultured embryonic stem (ES) cells
as well as their ability to differentiate into cardiomyocytes. Furthermore, we found that fluoxetine induced fluctuations in ectodermal marker gene expression during ES cell differentiation, which suggests that fluoxetine may affect neural development. In the present study, we investigated the effects of fluoxetine on the process of differentiation from ES cells into neural cells using the stromal cell-derived inducing activity (SDIA) method. Fluoxetine treatment was found to enhance the expression of glial marker genes following neural differentiation, as observed by immunocytochemical selleckchem analysis or quantitative RT-PCR. The promoter activity of glial marker genes was also significantly enhanced when cells were treated with fluoxetine, as observed by luciferase reporter assay. The expression of neuronal markers during ES cell differentiation into neural cells, on the other hand, was inhibited by fluoxetine treatment. In addition, FAGS analysis revealed an increased population of glial cells in the differentiating ES cells treated with fluoxetine. These results suggest that fluoxetine could facilitate the differentiation of mouse ES cells into glial cell lineage, which may affect fetal neural development. (C) 2010 Wiley-Liss, Inc.”
