Estradiol activates group I and II metabotropic glutamate receptor signaling, leading to opposing influences on cAMP response element-binding protein.
In addition to mediating sexual maturation and reproduction through stimulation of classical intracellular receptors that bind DNA and regulate gene expression, estradiol is also thought to influence various brain functions by acting on receptors localized to the neuronal membrane surface. Many intracellular signaling pathways and modulatory proteins are affected by estradiol via this unconvent...
متن کاملStudy of PKA binding sites in cAMP-signaling pathway using structural protein-protein interaction networks
Backgroud: Protein-protein interaction, plays a key role in signal transduction in signaling pathways. Different approaches are used for prediction of these interactions including experimental and computational approaches. In conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins inter...
متن کاملHomocysteine activates cAMP-response element binding protein in HepG2 through cAMP/PKA signaling pathway.
OBJECTIVE Hyperhomocysteinemia is an independent risk factor for cardiovascular disorders. Our previous studies demonstrated that hyperhomocysteinemia not only elicited inflammatory responses in the vascular endothelium but also induced fatty liver and hypercholesterolemia via transcriptional regulation. One of the transcription factors activated in the liver during hyperhomocysteinemia was cAM...
متن کاملGnRH stimulates LH release directly via inositol phosphate and indirectly via cAMP in African catfish.
In African catfish, two gonadotropin-releasing hormone (GnRH) peptides have been identified: chicken GnRH (cGnRH)-II and catfish GnRH (cfGnRH). The GnRH receptors on pituitary cells producing gonadotropic hormone signal through inositol phosphate (IP) elevation followed by increases in intracellular calcium concentration (¿Ca(2+)(i)). In primary pituitary cell cultures of male African catfish, ...
متن کاملGABA-cAMP response element-binding protein signaling regulates maturation and survival of newly generated neurons in the adult hippocampus.
Survival and integration of new neurons in the hippocampal circuit are rate-limiting steps in adult hippocampal neurogenesis. Neuronal network activity is a major regulator of these processes, yet little is known about the respective downstream signaling pathways. Here, we investigate the role of cAMP response element-binding protein (CREB) signaling in adult hippocampal neurogenesis. CREB is a...
