DECREASED PANCREATIC SOMATOSTATIN (SRIF) CONCENTRATION IN SPONTANEOUSLY DIABETIC MICE

Abstract
Spontaneously diabetic C57BL/6J obob and C57BL/Ks dbdb mice have significantly decreased immunoassayable pancreatic somatostatin concentrations compared to lean littermate controls at 11-12 wk: obob 1.06 .+-. 0.15 pg/.mu.g protein (n = 10) vs. control 1.94 .+-. 0.26 pg/.mu.g protein (n = 10) (mean .+-. SE; P < 0.005); dbdb 0.7 .+-. 0.2 pg/.mu.g protein (n = 8) vs. control 1.5 .+-. 0.2 pg/.mu.g protein (n = 8) (mean .+-. SE; P < 0.005). An inverse relationship between circulating insulin levels and pancreatic SRIF concentration is suggested.
