Evidence for an interaction between CB1 cannabinoid and melanocortin MCR-4 receptors in regulating food intake.

abstract：:There is evidence that the IGF system plays an important role in the growth and function of the thyroid gland. Proteolysis is an important posttranslational process that modulates the affinity of IGF binding proteins (IGFBPs) to IGFs, thus regulating their activity. IGFBP-3 has been shown to be cleaved by members of t...
