Somatostatin-14 and somatostatin-28 levels are light-driven and vary during development in the chicken retina

Brain Res Dev Brain Res. 1994 Mar 18;78(1):65-9. doi: 10.1016/0165-3806(94)90010-8.


The relative levels of somatostatin-14 and somatostatin-28 were determined during both perinatal development and variations in lighting conditions in the chicken retina. During perinatal development of the retina, somatostatin-14 predominated in recently hatched chickens, whereas somatostatin-28 predominated in the retinas of older chickens. In mature chickens, the levels of both somatostatin-14 and somatostatin-28 increased during the light and decreased during the dark. Our results suggest that these two forms of somatostatin are released proportionally and in parallel.
