Most of the lipid-soluble hormones such as steroid hormones enter the target cell to bind to their cytosolic or nuclear receptors and alter the expression of genes. These hormones stimulate the expression of some genes and inhibit that of others.
Binding of hormones to the cell surface receptors associated with ion channels regulates their opening and closing and thereby affects the membrane permeability. Likewise, the active hormone receptor complexes regulate the electrical signaling pathways of muscles and neurons.
