Scrambled Neuropeptide Y (scNPY) was similarly synthesized and contains the same amino acids as NPY, but scNPY is in a random sequence, it was used as a control in the research in NPY [1]. The sequence of scNPY is SKPQRDANREPTRYAIYDYSNPDIELHYLRPAYALG-NH2 [2].
Neuropeptide Y (NPY) is a 36-amino acid neuropeptide that exerts its activity via G-protein-coupled receptors. NPY is widely distributed in the peripheral and central nervous system. It modulates a variety of physiological processes, e.g. the central regulation of vasoconstriction, memory retention and food intake, and the regulation of circadian rhythm [2].
Scrambled NPY peptide treatment had no effect on VEGF expression in 4T1 cells. Previous treatment with scrambled NPY at concentrations ranging from 10−10 to 10−7 M made conditioned media from 4T1 cells show no difference in the number of complete endothelial networks or branch points versus control in endothelial tube formation assays [3].
In trimethyltin-treated (TMT-treated) rats, treatment with scrambled NPY for 24 h made the expression of Bdnf, NpyR, neurogenic and antiapoptotic genes comparable to that of saline-injected animals (without significant differences) [4]. In TMT-treated rats, both saline and scNPY showed no significant modulation (p> 0.05) in the expression levels of Npy1R, Npy2R and Npy5R [5].
