Increased levels of mRNA in the target tissue would indicate activation by the steroid hormone. Steroid hormones typically act by entering cells and binding to specific receptors, which then directly or indirectly affect gene expression, leading to increased synthesis of mRNA for specific proteins. This process is a hallmark of steroid hormone action, distinguishing it from non-steroid hormones that might act through second messengers like cyclic AMP or calcium ions.
