What is the difference between steroid and nonsteroid hormones?
Steroid hormones are epigenetic regulators of gene expression, [ 8, 9, 10] and Pmp22 expression in cultured Schwann cells can be stimulated with progesterone. [ 11, 12, 13] To determine whether circulating steroids can modulate the CMT phenotype, we treated a cohort of Pmp22 -transgenic male rats and wild-type controls with progesterone.
How do nonsteroid hormones work?
How do nonsteroid hormones work? Non-steroid hormones are made of amino acids. They are not fat soluble, so they cannot diffuse across the plasma membrane of target cells. Instead, a non-steroid hormone binds to a receptor on the cell membrane (see Figure below). The binding of the hormone triggers an enzyme inside the cell membrane.

What are the examples of non-steroid hormones?
Most endocrine hormones are non-steroid hormones. Examples include glucagon and insulin, both produced by the pancreas. Figure 12.3. 3: A non-steroid hormone binds with a receptor protein on the plasma membrane of a target cell.
