Collectively, it may be hypothesized that obesity induces feedback inhibition of pituitary GH secretion by increasing non-fasting serum FFA levels and the associated insulin resistance that causes compensatory intra-portal hyperinsulinemia and IGFBP-1 suppression, with the net result being low GH and normal IGF-I levels

The epigenome is highly responsive to various metabolic, cellular, and physiological signals [25, 26], and the immediate pre-pubertal period is clearly a particularly sensitive period for moderating SRD5A1 expression given that it is normally upregulated at this time, as seen also in other developmental genome-wide screens [86]
