Luteinizing hormone receptor knockout mouse: What has it taught us?

Area of Science:

• Reproductive Endocrinology
• Molecular Endocrinology
• Genetics

Background:

• Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) regulate gonadal function via the luteinizing hormone/choriongonadotropin receptor (LHCGR/LHR).
• Mutations in LHβ-subunit (LHB) and LHCGR genes cause hypogonadism, highlighting the critical role of this pathway.
• LHCGR/LHR is expressed in gonadal cells and several extragonadal tissues.

Purpose of the Study:

• To review the significant findings derived from LHR knockout (LuRKO) mouse models.
• To elucidate the diverse roles of LH/LHR signaling in reproductive and other biological processes.
• To highlight the contribution of LuRKO mice to understanding LHR function.

Main Methods:

• Review of experimental studies utilizing LHR knockout (LuRKO) mouse models.
• Analysis of data from LuRKO mice, often in combination with other genetically modified models.
• Examination of the impact of inactivated LHR function on physiological processes.

Main Results:

• LuRKO mouse models have provided critical insights into the function of LH and its receptor.
• These models have revealed novel and unexpected details regarding LH/LHR signaling pathways.
• Studies using LuRKO mice have confirmed the essential role of LH/LHR in gonadal development and function.

Conclusions:

• The LHR knockout mouse has been an invaluable tool for dissecting LH/LHR biology.
• Decades of research with LuRKO models have significantly expanded our knowledge of reproductive endocrinology.
• Further exploration using these models promises continued discoveries in the field.
