DESIGN : To investigate the possible role of this receptor in weight regulation , the whole coding region of the NPY Y 5 receptor gene was screened for mutations using temperature gradient gel electrophoresis ( TGGE ) . ^^^ Extended samples of these cohorts ( 160 obese children and adolescents ; mean body mass index ( BMI ) 33 . 5 + / 6 . 4 kg / m2 , 128 underweight subjects ; mean BMI 18 . 4 + / 1 . 0 kg / m2 and 58 patients with AN ; mean BMI 14 . 6 + / 1 . 7 kg / m2 ) were screened to determine the frequencies of a detected mutation and a detected polymorphism in the NPY Y 5 receptor gene . ^^^ RESULTS : The coding region of the NPY Y 5 receptor gene encompasses one exon . ^^^ Both tests for association and linkage to the NPY Y 1 and NPY Y 5 receptor polymorphisms were negative among all cohorts . ^^^ CONCLUSION : The results do not support a major role of the NPY Y 5 receptor gene in the variability of body weight in children and adolescents . . ^^^

We now report studies in which phosphothioate end protected antisense oligodeoxynucleotides ( ODNs ) targeted to prepro NPY ( prepro NPY antisense ODNs ) or to the Y 5 receptor ( Y 5 antisense ODNs ) were used to assess the functional importance of this novel receptor subtype in vivo . ^^^ Analysis of the structure of feeding behavior revealed that prepro NPY and Y 5 receptor antisense ODNs reduced food intake by inducing decreases in meal size and meal duration analogous to the orexigenic effects of NPY that are mediated by increases in these parameters . ^^^ Although changes in Y 5 receptor density could not be measured , the results with Y 5 antisense ODNs strongly suggest that this receptor subtype mediates the feeding response to exogenous and endogenous NPY . ^^^
