reproductive system
• less frequent estrus
|
• with irregular reproductive cycle
|
• reduced productive matings, number of litters, and litter size
|
• smaller and fewer liters with increased litter interval
|
nervous system
• Th+ ARC neurons exhibit reduced interburst intervals and enhanced instantaneous burst frequencies, increased variability of Vu and reduced burst strength causing a reduction in both depolarization envelope and spike frequency within a burst compared with wild-type cells
• Th+ ARC neurons exhibit loss of prolactin-evoked tonic excitation unlike wild-type mice
• however, rhythmic activity in the presence of prolactin remains intake
|
homeostasis/metabolism
• some female mice exhibit delayed luteinizing hormone peaks compared with wild-type mice
|
• however, female mice exhibit prolactin surges
