Transcription profiling of mouse bed nucleus of the stria terminalis and medial preoptic area

Project description:The effect of photoperiod on gene expression was assessed in punch samples of the bed nucleus of the stria terminalis and medial preoptic area. Long day mice were housed in 16L:8D and short day mice were housed in 8L:16D. Experiment Overall Design: For the medial preoptic area, independent samples were collected from long day (n=3) and short day (n=3) mice. For the bed nucleus of the stria terminalis independent samples were collected from long day (n=3) and short day (n=2) mice.

Acute (2 hr) response to rxLeptin injection in preoptic area/hypothalamus/pituitary of juvenile Xenopus laevis

Project description:Leptin binding to the leptin receptor (LepR) causes rapid signaling to the nucleus. We investigated the early (2 hr) transcriptional response to acute leptin injectio (intracerebroventricular) in the preoptic area/hypothalamus/pituitary of juvenile Xenopus laevis frogs. Frogs were given i.c.v. injections of 0.6% saline or recombinant X. laevis leptin (rxLeptin; 20 ng/g BW) and 2 hrs later killed and the preoptic area/hypothalamus/pituitary dissected.

Estrogen-Sensitive Medial Preoptic Area Neurons Coordinate Hypothermia and Hypometabolism in Mice

Project description:Homeotherms maintain a stable internal body temperature despite changing environments. During energy deficiency, some species can cease to defend their body temperature and enter a hypothermic and hypometabolic state known as torpor. Despite recent advances in our understanding of thermoregulation, the precise neurons that coordinate these profound thermoregulatory and metabolic changes remain largely unknown. Here, we demonstrate that estrogen-sensitive neurons in the medial preoptic area (MPA) are key drivers of hypothermia and hypometabolism in mice. We find that selectively activating estrogen-sensitive MPA neurons was sufficient to drive a coordinated depression of metabolic rate and body temperature similar to torpor, as measured by body temperature, physical activity, indirect calorimetry, heart rate, and brain activity. Inducing torpor with a prolonged fast revealed larger and more variable calcium transients from estrogen-sensitive MPA neurons during bouts of hypothermia. Finally, selective ablation of estrogen-sensitive MPA neurons demonstrated that these neurons are required for the full expression of fasting-induced torpor. Together, these findings suggest a role for estrogen-sensitive MPA neurons in directing the thermoregulatory and metabolic responses to energy deficiency.

Effects of early life adversity on male reproductive behavior and the medial preoptic area

Project description:Early life adversity has been linked to altered reproductive development in humans, including changes in the timing of pubertal onset and sexual activity. One common form of early life adversity is having limited access to resources. This form of early life adversity can be modeled in rodents using the limited bedding and nesting model (LBN), in which rat dams and pups are placed in a low resource environment from postnatal day (PND) 2 through 9. Our laboratory has previously shown that male rats raised in LBN conditions have elevated levels of plasma estradiol compared to control males. Female rats, on the other hand, show no effect of LBN on plasma hormone levels, pubertal timing, or estrous cycle duration in adulthood. Here, we find that LBN males also show changes in adult reproductive behaviors. LBN males acquired the suite of reproductive behaviors more quickly than their control counterparts over the course of 3 weeks of testing, showing shorter latencies to mount, intromit, and ejaculate compared to controls prior to the final week of testing. We also characterized LBN-induced gene transcription changes across sex in the medial preoptic area (mPOA) which underlies reproductive behaviors. Interestingly, there was no effect of LBN on puberty onset (as measured by preputial separation) or masculinization of the sexually dimorphic nucleus of the preoptic area (SDN/POA; as measured by calbindin immunoreactivity) in males, suggesting LBN may not exert effects on hormone-dependent measures until after puberty.

RNA-sequencing of preoptic area leptin receptor-expressing neurons from heat acclimated LepRCreHTB mice

Project description:This experiment intended to look for the transcriptome changes that happen in neuronal cells from the preoptic area of the hypothalamus expressing leptin receptors during heat acclimation conditions. 3 groups of animals were used; long-term heat-acclimated animals constantly exposed to 36˚C for 28-35 days, short-term heat-acclimated animals constantly exposed to 36˚C for 5 days, and non-habituated (non-acclimated) animals which were not exposed to heat. The animal line used was LepRCreHTB.
