Structural and proteomic repercussions of growth hormone receptor deficiency on the pituitary gland – lessons from a translational pig model

ABSTRACT: Growth hormone receptor deficiency (GHRD) results in low serum insulin-like growth factor 1 but high, non-functional GH levels. This study investigates the histomorphological and molecular alterations associated with GHRD. Pituitary glands from 6 months old GHR-KO pigs and control animals were compared using a quantitative stereological approach and label-free proteomics.

Growth hormone receptor deficiency (GHRD) results in low serum insulin-like growth factor 1 (IGF1) and high, but non-functional serum growth hormone (GH) levels in human Laron syndrome (LS) patients and animal models. This study investigated the quantitative histomorphological and molecular alterations associated with GHRD. Pituitary glands from 6 months old growth hormone receptor deficient (GHR-KO) and control pigs were analyzed using a quantitative histomorphological approach in paraffin (9 G  ...[more]
