Circular RNAs (circRNAs) are a large class of noncoding RNAs. Despite the identification thousands circular transcripts, biological significance most them remains unexplored, partly because lack effective methods for generating loss-of-function animal models. In this study, we focused on circTulp4, an abundant circRNA derived from Tulp4 gene that is enriched in brain and synaptic compartments. By creating circTulp4-deficient mouse model, which mutated splice acceptor site responsible...

Corticotropin-releasing hormone receptor 1 (CRHR1) activates the atypical soluble adenylyl cyclase (sAC) in addition to transmembrane cyclases (tmACs). Both cAMP sources were shown be required for phosphorylation of ERK1/2 triggered by activated G protein coupled (GPCR) CRHR1 neuronal and neuroendocrine contexts. Here, we show that promotes growth arrest neurite elongation hippocampal cells (HT22-CRHR1 cells). By characterising signalling mechanisms involved neuritogenic effect, demonstrate...

Class B G protein-coupled receptors (GPCRs) are involved in a variety of human pathophysiological states. These groups membrane less studied than class A GPCRs due to the lack structural information, delayed small molecule drug discovery, and scarce fluorescence detection tools available. The corticotropin-releasing hormone type 1 receptor (CRHR1) is key player stress response whose dysregulation critically stress-related disorders: psychiatric conditions (i.e. depression, anxiety,...

Hippocampal neurons exhibit activation of both the conventional transmembrane adenylyl cyclases (tmACs) and non-canonical soluble cyclase (sAC) as sources cyclic AMP (cAMP). These two cAMP play crucial roles in mediating signaling pathways downstream CRHR1 neuronal neuroendocrine contexts. In this study, we investigate involvement molecular mechanisms triggered by CRHR2α. Here provide evidence demonstrating that UCN1 UCN3 exert a neuritogenic effect on HT22-CRHR2α cells, which is solely...

ABSTRACT Corticotropin-releasing hormone receptor 1 (CRHR1) signaling initiates at the cell membrane and continues after internalization. A sustained cAMP generation ligand-activated CRHR1 endocytosis supported by soluble adenylyl cyclase (sAC) is required for G protein-independent phase of ERK1/2 phosphorylation in neuronal cells. Here, we report that Akt activated stimulation a mechanism dependent on endosomal production sAC activity. Moreover, AktS473 profile was distinct to...
