Steroid and thyroid hormones enter cells and directly alter mRNA production. Steroid hormones pass through cell membranes and bind to intracellular receptors, influencing gene expression. Thyroid hormones, which include thyroxine (T4) and triiodothyronine (T3), also enter cells and can alter gene expression by binding to thyroid hormone receptors in the nucleus.
