Thus, the acute and severe increase in blood pressure may solely be responsible for the BBB disruption in PAH mice and subsequently lead to abnormal sleep/wake behaviors. Several scores of aggressive behavior rose progressively with the advance of gestation and reached a maximum toward the time of parturition. Five THM and eight wild-type mice. The total NREMS time of female THM was similar to that of female wild-type mice (Figure 8D). Resident Physician in Cardio-Thoracic and Vascular Surgery. (G–I) Total time spent in REMS (G), REMS episode duration (H), and REMS episode number (I) before, during, and after pregnancy. Mice are social and care better for their young when they are housed with friends. The current findings showed similar changes during pregnancy between humans and mice, which provides a basis for preclinical studies for human diseases during pregnancy. Your comment will be reviewed and published at the journal's discretion. Analyses were carried out using two-sided tests and a statistical significance level of 0.05. REMS is characterized by θ (6–9 Hz)-dominant EEG and low amplitude of EMG. PAH mice exhibit elevated blood pressure with severe proteinuria during late pregnancy, which are diagnostic criteria for human preeclampsia [19, 20]; however, these animals have not been examined for neuropsychiatric phenotypes. During the course of pregnancy, the total daily wake time tended to decrease and was shortest during late pregnancy (710 ± 24.4 min), which was significantly shorter than that before and during early pregnancy (F = 6.622, df = 4, p < .0001; Figure 2A). For postpartum, we evaluated the third and fourth days after delivery because sleep/wake behaviors during the first 2 days after delivery varied widely depending on the time of delivery and the number of pups. They love being pregnant and don’t appear to have problems adjusting at all. Hormonal changes underlie the first component to appear in the pregnant mouse female, nest building; however the sound of pups can also induce nest building in non-pregnant nulliparious (virgin) females. Thank you for submitting a comment on this article. Furthermore, PAH mice may be useful as an animal model for eclampsia. The daily time spent in wakefulness decreased and the total NREMS time increased during late pregnancy, primarily reflecting increased NREMS during the dark phase, consistent with the long NREMS in pregnant rats [40, 41]. Sleep/wake behaviors of THM. Four electrode pins were lowered to the dura under stereotaxic control, and two flexible wires for EMG recording were inserted in the neck muscles and subsequently attached to the skull using dental cement. The mice get along fine . In most cases, the mice gave birth on day 19. For group comparisons among PAH, olmesartan-administered PAH, and THM, total δ density and REMS parameters were analyzed using one-way ANOVA followed by post hoc Tukey’s test. When the vaginal plug was observed, the male mouse was removed from the cage. (C) Power density during REMS before, during, and after pregnancy. PAH mice and nonpregnant THM were maintained on a C57BL/6 background. Before pregnancy, the daily total wake time of female mice was 868 ± 29.2 min, consistent with a previous report and much longer than that of male mice [38]. One-way ANOVA followed by Tukey’s test. A doe giving birth should never be disturbed. The data are presented as the mean ± SEM. Furthermore, we cannot exclude the possibility that humoral factors are involved in the altered sleep/wakefulness of PAH mice independently of high blood pressure. EEG signals were subjected to a fast Fourier transform analysis from 1 to 30 Hz with a 1-Hz bin using MATLAB (MathWorks)-based custom software. A general slowing of EEG in PAH mice during late pregnancy was confirmed by the high total δ density during late pregnancy compared with that during mid pregnancy (Figure 4A). de Gasparo M, Catt KJ, Inagami T, Wright JW, Unger T. Saito T, Ishida J, Takimoto-Ohnishi Eet al. However, postpartum mice showed significantly longer total wake time during the light phase than before pregnancy (F = 3.271, df = 4, p = .025; Figure 2A). Reference: Nagy A, Gertsenstein M, Vintersten K and Behringer R. 2003. Thus, an increased NREMS episode number may contribute to increased time spent in NREMS by overcoming the short NREMS episode duration. Does Investing in Low-income Urban Neighborhoods Improve Sleep? Two-tailed t-test. It is very common for the female mouse to have her smaller territory inside of the males larger territory. After recovery from anesthesia, the mice were housed individually and tethered to a counterbalanced arm (Instech Laboratories) that enabled the free movement and exerted minimal weight. Tsukuba hypertensive mice showed a normal time spent in wakefulness and NREM sleep and a decreased total REM sleep time. However, no studies have been conducted on sleep/wakefulness during pregnancy in mice. The total REMS time of female THM was shorter than that of female wild-type mice (Figure 8G). The male if present, may also participate in caring for pups (Weber & Olsson, 2008). For permissions, please e-mail journals.permissions@oup.com. Maternal interactions have implications in the physiological, psychological, and social development or mice and some of these effects remain into adulthood. EEG or EMG signals were amplified using a bioamplifier (#AB-611J, Nihon Koden), filtered (EEG: 0.3–300 Hz; EMG: 30–300 Hz), digitized at a sampling rate of 250 Hz, and displayed using LabView (National Instruments)-based custom-made software. Iida S, Baumbach GL, Lavoie JL, Faraci FM, Sigmund CD, Heistad DD. Consistently, receptors for estrogen are abundant in the preoptic area, which is involved in sleep regulation [50]. Note: Not all females will plug and not all plugged females will become pregnant; success rate varies by strain, male’s experience, conditions, etc. It might seem obvious, but like humans, only a female hamster can become pregnant. Don't feel the rat's uterine area to try to determine whether it's pregnant by movement, as even the most careful touch could damage the fragile fetuses if the rat is, indeed, pregnant. In addition, the administration of olmesartan alleviated sleep/wake behavior abnormalities of PAH mice during late pregnancy such as general slowing of EEG, loss of the circadian change in sleep/wakefulness, and a drastic reduction in REMS. We observed multiple and very light Evans blue leakages ranging in diameter from less than 0.4 mm to larger than 2 mm in the cerebral cortex and cerebellum in all PAH mice as reported in acute hypertensive rats [32], but did not find any leakage in normotensive control mice during late pregnancy (Figure 4E). Did you find this useful? Paul KN, Dugovic C, Turek FW, Laposky AD. The data are presented as the mean ± SEM. Pregnant mice, mice giving birth, and mice with new litters should be handled as little as possible. In a cage devoid of any enrichment (a fancy term for mouse toys), many strains display unfavorable behavior, including barbering, reduced eating and reduced breeding. For REMS, the power density during mid pregnancy was lower at 6 Hz (F = 10.101, df = 3, p = .001) and 7 Hz (F = 23.156, df = 3, p < .0001), and higher at 9 Hz (F = 14.724, df = 3, p < .0001) and 10 Hz (F = 9.019, df = 3, p = .002 for 10 Hz) compared with that before pregnancy (Figure 6C). Importantly, the sleep/wake behaviors of postpartum mice were similar to nonpregnant mice, despite lactation and increased prolactin and oxytocin. Decreasing Insulin Requirements in Pregnancy with Preexisting or Gestational Diabetes: Management Practices across Canada. As a normotensive control, we used pregnant human angiotensinogen transgenic mice mated with male human angiotensin transgenic mice.

(C) Representative 8-s EEG and EMG during wake, NREMS, and REMS during mid and late pregnancy and postpartum in a PAH mouse. *p < .05, **p < .01, ***p < .001. The present study showed that PAH mice exhibited markedly abnormal vigilance states with a generalized slowing of EEG during late pregnancy. Pregnant does will exhibit increased nesting behavior as the day of kindling approaches. Maternal care is crucial to a mouse pup's survival, as young in this altricial species are born hairless and with poorly developed sensorial and motor skills. It is unlikely that the removal of pups largely altered the sleep/wake behavior because PAH mice simply neglected the pups and did not show any interest in them. Pups born to mothers exposed to fluoxetine during pregnancy make fewer and briefer squeaks than those born to mothers who had no exposure to the drug, the new study found. The nest built by reproducing females is typically larger and more enclosed than the nests mice normally hide and sleep in (Weber & Olsson, 2008). Endometrial Receptivity and Embryo Implantation in Carnivores-Commonalities and Differences with Other Mammalian Species. The power density of PAH mice did not exhibit any significant difference during NREMS (Figure 6B). Consistent with the sleep analysis before pregnancy, we evaluated 4 days for early pregnancy (pregnant days 1–4), mid pregnancy (pregnant days 8–11), and late pregnancy (pregnant days 15–18). All PAH mice exhibited multiple focal leakages of Evans blue dye in the brain. Please check for further notifications by email. Restructuring maternal services during the covid-19 pandemic: Early results of a scoping review for non-infected women. In this study, we examined sleep/wakefulness in female C57BL/6 mice during pregnancy. The data are presented as the group mean ± SEM. In the present study, we evaluated sleep/wake behaviors during pregnancy in C57BL/6 mice by analyzing the electroencephalogram (EEG) or electromyogram (EMG), which provides a basis for future studies on the mechanism of sleep regulation during pregnancy. *p < .05. We further examined the EEG power spectrum of PAH mice, except for late pregnancy. The brain was removed and fixed in 4% paraformaldehyde/phosphate-buffered saline overnight at 4°C. In PAH mice, when a female angiotensinogen transgenic mouse conceives embryos carrying the human renin transgene, the pregnant mouse shows hypertension and proteinuria in late pregnancy because the human renin produced from the placenta processes human angiotensinogen into angiotensin I [9] and subsequently angiotensin II. For REMS, the power density at 4 and 5 Hz during late pregnancy was higher than that before pregnancy (F = 4.865, df = 4, p = .004 for 4 Hz; F = 10.561, df = 4, p < .0001 for 5 Hz; Figure 3C). And if an opening is not big enough to squeeze through, the mouse can gnaw it until it is big enough. Thus, an increased number of REMS episodes contributes to the increased total REMS time of olmesartan-administered PAH mice. Situations you ordinarily take for granted, such as riding in a car or engaging in sports, may provoke some anxiety. Unfortunately, if you got a pregnant mouse from the pet store she may be quite young and may not have the best mothering abilities. Each electrode has four electrode pins and two wires. Identify the sex of your hamster. (C) Power density during REMS before, during early and mid-pregnancy, and postpartum. Olmesartan treatment also decreased the total δ density of PAH mice to that of nonpregnant PAH (human angiotensinogen–transgenic) mice (Figure 7B). Hope you enjoy! Olmesartan-administered PAH mice had a systolic blood pressure of approximately 120 mm Hg, which does not affect the integrity of the BBB [39]. A playful chase is usually also a quieter chase; mice in a squabble tend to be more vocal. However, behavior of the offspring was altered. Altered REMS, independent of NREMS changes, supports the idea that the regulatory system for REMS functions differently from that for NREMS [44]. One hour later, the mice were transcardially perfused with cold phosphate-buffered saline and then 4% paraformaldehyde/phosphate-buffered saline. When a female mouse is pregnant, she'll instinctively begin building a nest for the birth. All procedures were approved by the Institutional Animal Care and Use Committee of the University of Tsukuba. However, blood pressures higher than the upper limit of cerebral vascular autoregulation can lead to disruption of the BBB and vasogenic edema, eventually resulting in hypertensive encephalopathy [39]. We also examined the sleep/wake behaviors of PAH mice and nonpregnant female THM. Bokil H, Andrews P, Kulkarni JE, Mehta S, Mitra PP. However, few sleep studies of pregnant women using polysomnography have been reported [6–8]. EEG spectrogram was drawn using multitaper method [36] (time-half bandwidth 3, number of tapers 5, window size 30 s, overlap 0.5) implemented in the Chronux tool box [37] for MATLAB. This study also proposes that PAH mice may be an animal model of eclampsia. Epochs containing movement artifacts were included in the state totals but excluded from subsequent spectral analysis. Continued progress in genetic engineering, including genome editing, has provided rapid progress in the genetics of sleep [11]. The EEG spectrum analysis of REMS showed pregnancy-induced changes at 6 and 7 Hz from the early stages of pregnancy, although the physiological significance of this finding is not clear. Indeed, modification of the Keap1-Nrf2 pathway, which functions as a defense system for oxidative stress, enhances placental angiogenesis and survival rates of PAH mice and their fetuses independently of high blood pressure [68]. We observed no difference in the REMS episode duration (Figure 5H) or REMS episode number (Figure 5I). There was no difference in the wake episode duration (Figure 8B) or the wake episode number (Figure 8C). (A) δ-Densities of all epochs during mid, late, and after pregnancy. Since we unequivocally identified REMS in PAH mice during late pregnancy based on the appearance of the θ wave (6–9 Hz) and muscle atonia (Figure 1C), we examined how the administration of olmesartan affects REMS in PAH mice. In late pregnancy, all PAH mice showed much fewer and slower spontaneous locomotion but they were still able to move in response to external stimuli, such as air puff and walked to obtain food and drink. By using optogenetic and pharmacogenetic approaches, the understanding of neural circuitries regulating sleep/wake behaviors has rapidly progressed [12]. Since PAH mice do not raise newborn pups and ignore them, we removed the newborn pups. Neuroimaging studies of eclampsia patients revealed posterior reversible encephalopathy syndrome, which refers to reversible vasogenic cerebral edema in the posterior region of the cerebral cortex accompanied by acute neuropsychiatric symptoms [28–31]. n = 6. EEG spectrum analysis during the course of pregnancy in wild-type mice. Oxford University Press is a department of the University of Oxford. After copulation, it will take a couple of weeks for physical signs of platy fish pregnancy to appear. Mice are only pregnant for 21 days. Since the systolic blood pressure of THM is similar to that of olmesartan-administered PAH mice, the sleep/wake behaviors of these mice allow us to examine how mild-to-moderate hypertension affects sleep. Thus, increased estrogen and progesterone during pregnancy may work to enhance wakefulness. Increased angiotensin II causes acute and severe hypertension with proteinuria in PAH mice [9, 25], which can be alleviated by olmesartan, an angiotensin II receptor blocker, from 150–160 to 120 mm Hg in late pregnancy, which was still higher than that of normal pregnant mice, 100–110 mm Hg [26, 27]. Habits of Mice | Mice Behavior. Sleep/wake behaviors of female C57BL/6 and PAH mice were examined based on electroencephalogram (EEG) or electromyogram recordings before, during, and after pregnancy. The sleep/wakefulness in each 20-s epoch was classified as nonrapid eye movement (NREM) sleep (NREMS), rapid eye movement (REM) sleep (REMS), or wakefulness using MatLab (MathWorks)-based semiautomated staging system followed by visual inspection. EEG spectrum analysis during the course of pregnancy in PAH mice, except for during late pregnancy. Thus, PAH mice bear a symptomatic resemblance to human eclampsia. Only male SERT/S mice showed social impairment and stereotyped behavior, and DHA supplementation ameliorated some of these behaviors. Behavior House mice walk, run and stand on all fours. There was no difference in the wake episode duration (Figure 5B) and wake episode number (Figure 5C). Thus, only when human renin exits, human angiotensinogen is processed into angiotensin I. This dosage of olmesartan decreases the systolic blood pressure of PAH mice to approximately 120 mm Hg [26, 27]. Major findings, such as long NREMS time during late pregnancy in wild-type mice and the abnormal sleep/wakefulness of PAH mice during late pregnancy, were sufficiently robust with small interindividual differences, which can be replicated with good reproducibility. Look for hair loss around nipples, nest-building behaviors, or an enlarged … The house mouse has a sharp sense of hearing and communicates with other house mice through squeaks. Some women appear to breeze through pregnancy with no problems at all. Consistently, angiotensin II type-1a receptor is required for the high blood pressure in PAH mice [57]. (C–E) Total time spent in REMS (C), REMS episode duration (D), and REMS episode number (E) in nonpregnant PAH mice, olmesartan-administered PAH mice, and THM. C57BL/6 mice showed a decreased total wake time and increased nonrapid eye movement (NREM) sleep time during late pregnancy. Consistent with the short total wake time during late pregnancy, the daily time spent in NREMS during late pregnancy was longer than that before and during early pregnancy (F = 8.620, df = 4, p = .0001; Figure 2D). The Oxytocin Receptor: From Intracellular Signaling to Behav-ior. In addition, we failed to obtain pregnant female THM and thus could not examine sleep/wake behaviors of pregnant THM compared with PAH mice. Similarly, the total wake time during the dark phase during late pregnancy was significantly shorter than that before and during early pregnancy (F = 5.949, df = 4, p = .001; Figure 2A). (B) Power density during NREMS before, during early and mid pregnancy, and postpartum. Haruna Komiya, MD, Chika Miyoshi, PhD, Kanako Iwasaki, BSc, Noriko Hotta-Hirashima, MS, Aya Ikkyu, MS, Satomi Kanno, Takato Honda, BSc, Masahiko Gosho, PhD, Hiromi Hamada, MD, PhD, Toyomi Satoh, MD, PhD, Akiyoshi Fukamizu, PhD, Hiromasa Funato, MD, PhD, Masashi Yanagisawa, MD, PhD, Sleep/Wake Behaviors in Mice During Pregnancy and Pregnancy-Associated Hypertensive Mice, Sleep, Volume 41, Issue 3, March 2018, zsx209, https://doi.org/10.1093/sleep/zsx209. Although most behavioral studies have been conducted using male C57BL/6 mice, male-biased research results may hinder the characterization of sexually dimorphic effects, which may lead to an underestimation of risks for females [15]. The EEG spectrum of PAH mice in late pregnancy showed a decrease in high frequency power (>8 Hz) (Figure 1D), lacked a clear difference between the light and dark phases, and lacked any stretch of wake or sleep epochs (Figure 1D). As an animal model of preeclampsia, pregnancy-associated hypertensive (PAH) mice have been developed by crossing female mice carrying the human angiotensinogen transgene with male mice carrying the human renin transgene [9]. MY is a former Investigator of the Howard Hughes Medical Institute. For PAH mice, female mice carrying the human angiotensinogen transgene were mated with a male mouse carrying the human renin transgene. Similarly, the most commonly observed EEG abnormality in human eclampsia is generalized or focal slowing of EEG [28, 58, 59], and this abnormal EEG normalizes after the release from hypertension [59]. One-way repeated measures ANOVA followed by Tukey’s test. the mouse strains produced are genetically well defi ned. Steegers EA, von Dadelszen P, Duvekot JJ, Pijnenborg R. Chaiworapongsa T, Chaemsaithong P, Yeo L, Romero R. Chaiworapongsa T, Chaemsaithong P, Korzeniewski SJ, Yeo L, Romero R. Abalos E, Cuesta C, Carroli Get al. For NREMS, power density at 4 Hz during late pregnancy was higher than that before pregnancy and during early pregnancy (F = 13.384, df = 4, p < .0001; Figure 3B). After delivery, blood pressure started to decrease and returned to 100–110 mm Hg by the third day after delivery [9, 25]. A short REMS episode duration was recognized from mid pregnancy through postpartum. Pregnancy palpation is most readily carried out on older, multiparous females who have looser skin and are more accustomed to being handled. The number of wake episodes during late pregnancy was higher than that during any other periods (F = 10.408, df = 4, p < .0001; Figure 2C). Prozac puzzle: (G–I) Total time spent in REM sleep (REMS) (G), REMS episode duration (H), and REMS episode number (I). (A–C) Total time spent in wake (A), wake episode duration (B), and wake episode number (C) of THM and wild-type mice. Furthermore, many gene-modified mice have been developed as animal models of human diseases, including preeclampsia [9] and the sleep disorder narcolepsy [10], which enables the examination of how pregnancy affects the phenotypes of animal models. Parry BL, Fernando Martínez L, Maurer EL, López AM, Sorenson D, Meliska CJ. Back to Top ... in order to minimize mouse-to-mouse variations in phenotype, the genetic background of a colony should be as uniform as possible. Cold Spring Harbor Laboratory Press. Youssef AM, Hamidian Jahromi A, Vijay CG, Granger DN, Alexander JS. (B) Power density during NREMS before, during, and after pregnancy. The NREMS episode duration and episode number were similar before, early, mid, and after pregnancy (Figure 5E and F). is in danger, running around the cage, carrying young here and there and dropping them. An acute increase in arterial blood pressure by 80 mm Hg disrupts the BBB integrity in rats [60]. She may become so anxious that (A) Power density during wake before, during early and mid pregnancy, and postpartum in PAH mice. (D) Representative daily EEG spectrogram during mid and late pregnancy and postpartum in a PAH mouse. All mice were allowed at least 4 days of recovery from surgery and habituation to the recording conditions for at least 3 days. A few months ago I bought a pregnant mouse, she had 9 beautiful babies, but I kept the really cute ones and I left them with mom longer than I should've, my mistake.. 2 male babies were left with mom for 6 weeks or so and then I realized they can inbreed so I immediately separated them and now the mother seems to be getting round again, I weighed her on the kitchen … (D–F) Total time spent in NREMS (D), NREMS episode duration (E), and NREMS episode number (F) before, during, and after pregnancy. (A–C) Total time spent in wake (A), wake episode duration (B), and wake episode number (C) before, during early and mid pregnancy, and postpartum in PAH mice. Total REMS time, REMS episode duration, and REM episode number of THM were similar to those of olmesartan-administered PAH mice (Figure 7C, D, and E). Adopting 6 Mice (Vlog #5) - Duration: 6:59. The data are presented as the mean ± SEM. The total wake time was similar among before, early, mid, and after pregnancy (Figure 5A). They become more active at night and are always looking for food sources. Mice are suitable model species for examining sleep/wakefulness during pregnancy because they have a gestation period of less than 3 weeks. The REMS episode duration during the light phase before pregnancy was longer than that during mid, late, and after pregnancy (F = 8.652, df = 4, p < .0001; Figure 2H). Maternal behavior is elicited through a combination of hormonal factors and external stimuli from the pups. (G–I) Total time spent in REM sleep (REMS) (G), REMS episode duration (H), and REMS episode number (I) before, during early and mid pregnancy, and postpartum in PAH mice. That’s where the similarities between the lovable adolescent and the less-than-adorable house mouse end. We thank all Yanagisawa/Funato lab and IIIS members for discussion and comments on this manuscript and Go Taniguchi for his comments on spike-wave seizures. Indeed, those few studies on sleep/wakefulness in female mice did show sex differences in sleep [16–18]. Because of these changes, we could not determine wakefulness or NREMS for many epochs. One-way ANOVA followed by Tukey’s test. © Sleep Research Society 2017. She may be more likely to abandon or even cannibalize her babies. Sleep parameters of THM and wild-type mice were compared using Student’s t-test. However, no studies have been conducted on... Introduction. (A) Representative 8-s EEG and EMG during wake, NREMS, and REMS during mid and late pregnancy and postpartum in a wild-type mouse. Sivadas N, Radhakrishnan A, Aswathy BS, Kumar VM, Gulia KK. Gabriel Goh 26,679 views. It will fall out within hours and dissolves in a days time. Total time spent in wakefulness, NREMS, and REMS was derived by summing the total number of 20-s epochs in each state. INTRACELLULAR SIGNALING TO BEHAVIOR Benjamin Jurek and Inga D. Neumann Department of Behavioural and Molecular Neurobiology, Institute of Zoology, University of Regensburg, Regensburg, Germany L Jurek B, Neumann ID. The data from individual mice are presented as the group mean ± SEM. Each treatment was completed within 5 min. Using the mouse model, we examined autistic-like behaviors in greater detail, and additionally explored whether diet supplementation with docosahexaenoic acid (DHA) may mitigate the behavioral changes. Olmesartan-administered PAH mice did not show general slowing of EEG. Sleep/wake behaviors during the course of pregnancy in PAH mice, except for during late pregnancy. Using histological techniques this chapter tracks the microscopic changes that occur in the mouse implantation site from implantation to parturition focusing on placental and vascular development, and immune cell populations. Preeclampsia is a pregnancy complication characterized by hypertension and proteinuria after 20 weeks of gestation in patients without hypertension prior to pregnancy [19–22]. To examine whether high blood pressure disrupts the integrity of the blood–brain barrier in PAH mice, Evans blue dye was injected intravenously. XXIII. The total wake time of female THM was similar to that of female wild-type mice (Figure 8A). (A–C) Total time spent in wake (A), wake episode duration (B), and wake episode number (C) before, during, and after pregnancy in wild-type mice.
