: The T-box sequence of RXR possesses a high degree of structural freedom, allowing for the formation of cooperative protein–DNA complexes necessary for targeting specific genes. 2. Neurological Impact and Synaptic Plasticity
: High glucose levels can suppress the transcriptional activity of RAR/RXR, promoting oxidative stress and cardiomyocyte apoptosis . This is linked to the phosphorylation and degradation of the receptors via the JNK pathway. FrSi_TCRSR.part5.rar
: Research shows that the Zn–II regions of nuclear receptors undergo helix-to-loop transitions when binding to or dissociating from DNA. : The T-box sequence of RXR possesses a
: Dysfunction in the RAR/RXR pathway can lead to the downregulation of RARβ , causing impairments in AMPA-mediated synaptic transmission and long-term potentiation (LTP). This is linked to the phosphorylation and degradation
The RXR–RAR–DR5 complex is a primary driver of gene expression. This complex functions through:
Disruptions in these pathways have significant effects on brain function, particularly in the hippocampus:
