The PCR profiles for letpin, NPY and a-actin consisted of denaturation at 94[degrees]C for 2 min, followed by appropriate number of cycles (Table 1) with denaturation at 94[degrees]C for 50 sec, annealing at the optimum temperature (Table 1) for 50 sec, and extension at 72[degrees]C for 50 sec, and a final extension at 72[degrees]C for 10 min.
Bi says the results "made sense," given that NPY has been shown to stimulate eating.
The researchers used three different approaches, each with a varying number of research subjects ranging from 58 to 152, to study the link between NPY gene expression and emotional processing.
Those with low NPY were more negative both before and after the pain - meaning they were more emotionally affected while anticipating the pain and while reflecting on their experience immediately afterward.
This expanded application of Neurogen's NPY obesity drug development program to include companion animals offers a new and potentially quite lucrative addition to our product pipeline," said Harry H.
Experiments on mice subsequently confirmed that the NPY promotes atherosclerosis, according to the report published in the Public Library of Science journal.
NGD 95-1 is an orally active small molecule antagonist of neuropeptide Y (NPY) receptors and is presumed to be the first NPY blocker to be tested in humans.
CRF is known to stimulate activities leading to increased serum glucose and free fatty acids, and NPY is known to induce obesity and insulin resistance, all factors associated with Type 2 diabetes.
Josephine Lai at the University of Arizona evaluated siRNAs that target the gene for NPY, a pain-associated peptide.
The importance of another appetite-related neuropeptide NPY in hypothalamic regulatory activities has been already identified.
In man, the neurotransmitter NPY communicates with four well-known 'cell surface receptors' in the brain (Y1, Y2, Y4 and Y5), which in turn trigger the system's effects.
The objective of this study was to determine whether this pathway is common for adaptogens and whether NPY and/or Hsp72 can be considered as necessary specific biomarkers for adaptogenic activity.
