: Some RAR types can cell-specifically override others, creating artificial redundancies often observed in gene disruption studies. 4. Pathophysiological Implications (Diabetes and Cancer)
: 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
: Only RARγ can mediate differentiation in wild-type F9 cells, while either RARα or RARγ can trigger it in P19 cells. : Some RAR types can cell-specifically override others,
Studies in F9 and P19 cell lines reveal complex "functional redundancies" where different types of RAR (α, β, γ) can sometimes substitute for one another: This is linked to the phosphorylation and degradation
: Research shows that the Zn–II regions of nuclear receptors undergo helix-to-loop transitions when binding to or dissociating from DNA.
