A decline in female baboon hypothalamo-pituitary-adrenal axis activity anticipates aging

Figure 4. The effects of age on area% positive staining of proteins in pituitary of female baboons (P. hamadryas). POMC expression showed negative age-related linear regression in anterior pituitary (n = 12, R = -0.63, P < 0.05). GR and p-GR were not correlated with age. Scale bar (100µm) applies to all micrographs.
