The brain cells containing these mRNA's can then be isolated and their mRNA's decoded to determine just what their protein products are and how closely the products resemble the true peptide hormones.

The researchers went on to study what is responsible for the difference in expression of the glucocorticoid-receptor gene.

Stop focusing on “how many calories did I burn” with exercise. Focus on “what hormonal response am I giving my body for the next 24-48 hours?”
