Background: Somatostatin analogues inhibit peptide release and cell growth through multiple postreceptor signal transduction mechanisms (PRSTM), including G proteins (GP), cyclic adenosine monophosphate (cAMP), calcium, protein kinase C (PKC), and tyrosine phosphatase (TP). Octreotide acetate (OA), a somatostatin analogue, has been shown to inhibit angiogenesis; however, the PRSTM involved are unknown.
Methods: Fertilized chicken eggs were obtained and incubated.
