Key result
In rats, IGFBP-2 mRNA levels increased 10- to 20-fold after hypophysectomy or fasting, whereas IGFBP-1 mRNA remained relatively unchanged.
The study demonstrates differential tissue distribution and hormonal regulation of IGFBP-1 and IGFBP-2 mRNAs in rats, with IGFBP-2 being highly responsive to fasting and hypophysectomy.

IGFBP-2 shows unique sensitivity to pituitary and nutritional status in rats; extends preclinical knowledge but leaves open human translation.
Ooi et al. (1990) studied Hypophysectomy, fasting, or streptozotocin-induced diabetes in rats. Hypophysectomy, fasting, or streptozotocin-induced diabetes vs. Baseline or control state was evaluated on Expression levels of IGFBP-1 and IGFBP-2 mRNAs. In rats, IGFBP-2 mRNA levels increased 10- to 20-fold after hypophysectomy or fasting, whereas IGFBP-1 mRNA remained relatively unchanged.
