Hormone … Webmodulation of gene expression is the binding of the hormone ligand to its cognate receptor, leading to ‘activation’, dimerization and interaction of the receptor with hormone response elements (HREs), nucleotide sequences positioned mostly in the regulatory regions of hormone-inducible genes. The receptor then interacts with
WebThe hormone binds with the receptor forming a receptor-hormone complex(“H”). This complex can pass through the nuclear membrane (“D”) at a nuclear pore (“E”), where it … WebThyroid hormone influences the expression of a number of nuclear encoded respiratory genes at the level of mRNA and enhances expression of mitochondrially encoded respiratory genes. Therefore, thyroid hormone appears to affect gene regulation in two different cell compartments. The current evidence for a direct thyroid hormone/thyroid receptor ...
WebSome cells simply lack the ability to “see” the hormone and do not respond to its presence. Competency to perceive a hormone depends on a cell’s physiology when the hormone is present. If the hormone is perceived, its unique chemical structure causes a chain reaction or signal transduction that involves changes in gene expression and cell ...
