Abstract

In a search for new appetite-controlling signals, the peptide nesfatin-1, expressed in the brain and peripheral tissues of rodents and humans has been reported to regulate feeding by reducing food intake. Recently it has also been reported that nesfatin-1 might be involved in regulating the reproductive axis in fishes and mammals, but its expression and physiological role if any, is not yet known in birds. In the present study, localization and expression of nesfatin-1 was observed in the testis, ovary and shell gland of poultry species Japanese quail, Coturnix coturnix japonica. Our earlier studies have reported that serotonin precursor 5-HTP and dopamine precursor l-DOPA given 8h apart induces gonadal suppression, when given 12h apart leads to gonadal stimulation while other relationships were found ineffective. In the present study intense ir-nesfatin-1 was observed in the regressed ovary (stromal cells) and shell gland (endometrium) of 8-h Japanese quail while in 12-h quail, weak and scarce immunostaining for nesfatin-1 was detected in the hyperactive ovary and shell gland compared to control. These findings led us to conclude that, an inverse relationship exists between ovarian activity (both in the control and simulated c...Continue Reading
