General description

GT1-7 is an immortalized mature mouse hypothalamic GnRH neuronal cell line. Immortalized GnRH neurons were generated by introducing a transgene containing the promotor region of the GnRH gene coupled to the coding region of the SV40 T-antigen oncogene into transgenic mice1. The resulting anterior hypothalamic tumors were removed from one of the mice and the cells dissociated and cloned. GT1-7 is a clonal line of mature differentiated GnRH neurons that exhibit high levels of Gnrh1 mRNA and secrete GnRH in response to depolarization.
Gonadotrophin-releasing hormone (GnRH) is a neuropeptide that is synthesized and released from GnRH neurons within the hypothalamus and is required for normal reproductive development and function. The scarcity and scattered distribution of GnRH neurons in the rostral hypothalamus make the biological study of the cells difficult.

By genetically targeting tumorigenesis to specific hypothalamic neurons in transgenic mice using the promoter region of the gonadotropin-releasing hormone (GnRH) gene to express the SV40 T-antigen oncogene, we have produced neuronal tumors and developed clonal, differentiated, neurosecretory cell lines. These

An immortalized hypothalamic neuronal cell line was recently developed by genetically targeting the expression of the simian virus-40 large T-antigen in LHRH neurons. These GT1 cells were subcloned to GT1-1, GT1-3, and GT1-7 cells, and they have been shown to

Mammalian reproduction is dependent upon intermittent delivery of luteinizing hormone-releasing hormone (LHRH) to the anterior pituitary. This mode of secretion is required to sensitize maximally the gonadotrophs to LHRH stimulation and to regulate gonadotropin gene expression. While LHRH secretion is
