Although pro-opiomelanocortin (POMC) is a well-known hormone precursor in many species, molecular information about avian POMCs is still relatively scarce. In a former study (Berghman et al., [1998] Mol Cell Endocrinol. 142:119-130) the nucleotide and amino acid sequence of N-terminal POMC in the chicken were reported. To complete the nucleotide sequence of(More)
Monoclonal antibodies (Mabs) specifically recognizing the chicken pituitary corticotropes were used to isolate a population of closely related peptides from crude chicken pituitary extracts. A homogeneous N-terminal sequence homologous to the extreme N-terminus of mammalian and amphibian pro-opiomelanocortin (POMC) was revealed. Further physicochemical(More)
Although, since the isolation of pituitary adenylate cyclase-activating polypeptide (PACAP), a wealth of literature has been published describing its localization, binding sites, and biological activities in a variety of mammalian tissues, only very little is known about PACAP in avian species. Therefore, in order to find out the sites of actions of PACAP(More)
To map in detail the brain areas in which pituitary adenylate cyclase-activating polypeptide (PACAP) may play a significant role in birds, the distribution of PACAP and PACAP type I receptor (PAC(1)-R) mRNA was examined throughout the entire chicken brain by using in situ hybridization histochemistry. Widespread distribution of both PACAP and its receptor(More)
BACKGROUND/AIMS LRRK2 (leucine-rich repeat protein kinase 2) is one of the most commonly accepted genes associated with Parkinson's disease (PD). The overexpression of disease-associated mutations in LRRK2 is toxic to the cells, while reduction or elimination of LRRK2 expression promotes cell health and growth. Thus, the identification of an LRRK2 inhibitor(More)
