Abstract
Serotonin (5-HT) acts as a neuromodulator and plays a critical role in brain development. Changes in 5-HT signaling during the perinatal period can affect neural development and may result in behavioral changes in adulthood; however, further investigations are necessary including both sexes to study possible differences. Thus, the aim of this study was to investigate the impact of neonatal treatment with fluoxetine on the development of male and female offspring. The animals were divided into four groups according to sex and treatment. The experimental groups received fluoxetine at 10 mg·kg-1 (1 μL/g of body weight (bw)) and the animals of control group received saline solution 0.9% (1 μL/g of bw) from postnatal days 1-21. In the neonatal period, reflex ontogeny, somatic development, physical features, and food intake were recorded. In the postnatal period (until day 31) bw and post-weaning food intake were recorded. Chronic administration of fluoxetine in the neonatal period caused a delay in the reflex ontogeny and somatic development, as well as reduction of lactation, post-weaning bw, and post-weaning food intake in rats. No difference was found between the sexes. These changes reaffirm that serotonin plays an important role in regulating the plasticity of the brain during the early development period, but without sex differences.

Abstract
PURPOSE Associations have been made between maternal selective serotonin reuptake inhibitor (SSRI) use during pregnancy and altered behavior in offspring, including an increased risk of autism. Given the important role serotonin plays in behavior, we hypothesized SSRI exposure in the perinatal period would alter central serotonin receptor expression and program adult behaviors in mice. METHODS Female mice were injected with sertraline or saline throughout pregnancy. Offspring continued to receive injections on postnatal days 1-14, a time period in mice similar to the third trimester in human pregnancy. Adult offspring underwent behavioral testing, and serotonin receptor mRNA levels were quantified. RESULTS Compared to controls, SSRI exposed mice did not have a reduction in social interactions, spatial learning, or exploratory behavior. As adults, sertraline exposed mice had significantly increased mRNA levels of multiple 5-HT receptors, serotonin transporter (5-HTT), and tryptophan hydroxylase isoform 2 in the cerebral cortex. CONCLUSION Although no behavioral phenotype was observed, SSRI exposure in the perinatal period permanently alters cerebral receptor mRNA levels. We speculate these shifts in mRNA expression provide important compensation during SSRI exposure. Further pre-clinical and clinical investigation into additional serotonin-regulated phenotypes is necessary to further assess the long-term implications of perinatal SSRI exposure.

Oral oestrogen reverses ovariectomy-induced morning surge hypertension in growth-restricted mice. Clin Sci (Lond) 2016; 130:613-23.

Abstract
Perinatal growth restriction (GR) is associated with heightened sympathetic tone and hypertension. We have previously shown that naturally occurring neonatal GR programmes hypertension in male but not female mice. We therefore hypothesized that intact ovarian function or post-ovariectomy (OVX) oestrogen administration protects GR female mice from hypertension. Utilizing a non-interventional model that categorizes mice with weanling weights below the tenth percentile as GR, control and GR adult mice were studied at three distinct time points: baseline, post-OVX and post-OVX with oral oestrogen replacement. OVX elicited hypertension in GR mice that was significantly exacerbated by psychomotor arousal (systolic blood pressure at light to dark transition: control 122 ± 2; GR 119 ± 2; control-OVX 116 ± 3; GR-OVX 126 ± 3 mmHg). Oestrogen partially normalized the rising blood pressure surge seen in GR-OVX mice (23 ± 7% reduction). GR mice had left ventricular hypertrophy, and GR-OVX mice in particular had exaggerated bradycardic responses to sympathetic blockade. For GR mice, a baseline increase in baroreceptor reflex sensitivity and high frequency spectral power support a vagal compensatory mechanism, and that compensation was lost following OVX. For GR mice, the OVX-induced parasympathetic withdrawal was partially restored by oestrogen (40 ± 25% increase in high frequency spectral power, P<0.05). In conclusion, GR alters cardiac morphology and cardiovascular regulation. The haemodynamic consequences of GR are attenuated in ovarian-sufficient or oestrogen-replete females. Further investigations are needed to define the role of hormone replacement therapy targeted towards young women with oestrogen deficiency and additional cardiovascular risk factors, including perinatal GR, cardiac hypertrophy and morning surge hypertension.

Abstract
Neonatal exposure to a selective serotonin reuptake inhibitor (SSRI) leads to decreased left ventricular volumes and sympathetic activation in adult mice. We hypothesized this neonatal SSRI exposure-induced small left heart syndrome would increase post-myocardial infarction (MI) morbidity and mortality. C57BL/6 mice received saline or sertraline (5 mg/kg intraperitoneally) on postnatal days 1-14. At 5 months, male mice underwent coronary artery ligation and were monitored by radiotelemetry until death or 4 weeks after ligation. After ligation, SSRI-exposed mice had increased heart rates (SSRI, 516 ± 13 bpm; control, 470 ± 15 bpm; P < 0.05). SSRI-exposed mice had significant reductions in left ventricular systolic volumes both before and after coronary ligation (SSRI: baseline = 20 ± 3 μL, post-MI = 37 ± 10 μL; control: baseline = 30 ± 3 μL, post-MI = 65 ± 23 μL). Post-MI echocardiography showed significantly decreased ejection fraction in control mice (baseline = 60% ± 4%, post-MI = 41% ± 2%, P < 0.01) but not the SSRI-exposed mice (baseline = 65% ± 3%, post-MI = 53% ± 7%). Neonatal SSRI exposure did not significantly alter post-MI survival. We conclude that the preexisting SSRI-induced small left heart syndrome may provide protection from post-MI ventricular dilation.

Abstract
Intrauterine growth restriction and premature delivery decrease circulating levels of the neurotrophic hormone leptin and increase the risk of adult psychiatric disease. In mouse models, neonatal leptin replacement normalizes brain growth and improves the neurodevelopmental outcomes of growth restricted mice, but leptin supplementation of well-grown mice decreases adult locomotor activity. We hypothesized isolated neonatal leptin deficiency is sufficient to reduce adult brain volumes and program behavioral outcomes, including hyperactivity. C57Bl/6 pups were randomized to daily injections of saline or PEG-leptin antagonist (LX, 12.5 mg/kg) from postnatal day 4 to 14. After 4 months, fear conditioning and open field testing were performed followed by carotid radiotelemetry for the measurement of baseline activity and blood pressure. Neonatal LX did not significantly increase cue-based fear or blood pressure, but increased adult locomotor activity during assessment in both the open field (beam breaks: control 930 ± 40, LX 1099 ± 42, P<0.01) and the home cage (radiotelemetry counts: control 4.5 ± 0.3, LX 5.6 ± 0.3, P=0.02). Follow-up MRI revealed significant reductions in adult frontal cortex volumes following neonatal LX administration (control 45. 1 ± 0.4 mm(3), LX 43.8 ± 0.4 mm(3), P=0.04). This was associated with a significant increase in cerebral cortex leptin receptor mRNA expression. In conclusion, isolated neonatal leptin deficiency increases cerebral cortex leptin receptor expression and reduces frontal cortex volumes in association with increased adult locomotor activity. We speculate neonatal leptin deficiency may contribute to the adverse neurodevelopmental outcomes associated with perinatal growth restriction, and postnatal leptin therapy may be protective.

Abstract
BACKGROUND Sertraline, a selective serotonin reuptake inhibitor (SSRI), is the most commonly prescribed therapy for maternal depression. Epidemiologic studies have linked SSRI exposure with decreased fetal growth, altered autonomic regulation, and cardiac malformations. We hypothesized that SSRI exposure decreases left-ventricular (LV) volumes and increases adult sympathetic nervous system activation, resulting in increased adult heart rates. METHODS C57BL/6 mice received saline or sertraline (5 or 15 mg/kg/day i.p.) on postnatal days 1-14. Adult phenotypes were assessed at 5 mo. RESULTS Sertraline-exposed mice had smaller LV internal diameters in diastole (control 4.0 ± 0.1 mm, SSRI 3.7 ± 0.1 mm, P < 0.05), decreased stroke volumes (control 46 ± 2.6 µl, SSRI 37 ± 2.3 µl, P < 0.05), higher heart rates (control 530 ± 13 beats per minute (bpm), SSRI 567 ± 6 bpm, P <0.05), and increased urinary excretion of noradrenaline (control 174 ± 29.4 ng/ml, SSRI 276 ± 35.1 ng/ml, P < 0.05). These changes were associated with increased cerebral serotonin transporter (5-HTT) expression. CONCLUSION Neonatal sertraline exposure causes long-term changes in cardiac morphology and physiology. We speculate that early-life SSRI exposure impairs cardiomyocyte growth and central serotonin signaling, leading to a small left heart syndrome in adult mice.
