A full-length cDNA encoding the goose (Anser anser) leptin receptor (LEPR) was cloned and sequenced. The goose LEPR gene encodes a 1,156-amino acid protein containing a signal peptide, a single transmembrane domain and specific motifs involving putative leptin-binding and signal transduction. The deduced goose LEPR protein shows more than 90% identity to duck and 75% identity to chicken and turkey. Quantitative real-time analysis reveals that the goose LEPR is predominantly expressed in brain. The expression of LEPR in goose adipocytes can be up-regulated by oleic acid in vitro. Moreover, the expression levels of genes, which have been demonstrated to be related to adipocyte differentiation, are down-regulated in LEPR-knockdown adipocytes, indicating LEPR's potential role in adipocyte differentiation in goose.

Leptin was known as a pivotal regulator for the control of food intake and energy expenditure. However, leptin has also been found to be involved in the regulation of female reproductive system through interactions with pathways in the hypothalamic-hypophyseal axis and direct action at the ovarian level. In the present study, granulosa cells from goose ovarian preovulatory (F1-F3) follicles were cultured with leptin (0, 1, 10 or 100ng/ml).

Leptin is critical for reproductive endocrinology. The aim of this study is to assess the expression patterns of leptin receptor (Lepr) during ovarian follicle development and to reveal the mechanism by which leptin affects steroid hormone secretion in goose granulosa cells. Transcripts of Lepr were ubiquitous in all tested tissues, with pituitary and adrenal glands being the predominant sites.
