Behav Brain Res 2020; 399:113000. [PMID: 33161032 DOI: 10.1016/j.bbr.2020.113000] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 10/08/2020] [Accepted: 11/02/2020] [Indexed: 11/30/2022]
Abstract
A large body of literature has demonstrated that prenatal stress (PS) can induce depression-like behavior in the offspring. However, the underlying mechanism remains largely unknown. CREB-regulated transcriptional coactivator 1(CRTC1) has recently been shown to involve in mood regulation. This research aims to investigate whether CRTC1 signaling was involved in the depression-like behavior of prenatally stressed offspring rats. Sucrose preference test (SPT), forced swimming test (FST) and open field test (OFT) were adopted to test the depression-like behavior in the male offspring rats, and CRTC1 signaling was measured. The results showed that there were significantly reduced sucrose intake in SPT and prolonged immobility time in FST in PS-exposure offspring rats. It was also found decreased levels of total CRTC1, nuclear CRTC1, calcineurin, brain-derived neurotrophic factor (BDNF) and c-fos, but increased cytoplasmic p-CRTC1 in the hippocampus (HIP) and prefrontal cortex (PFC) of the offspring rats. Furthermore, the mRNA level of CRTC1, calcineurin, BDNF, c-fos were down-regulated. Abnormal expression of CRTC1 signaling could be alleviated by fluoxetine treatment. In conclusion, our research indicated that the aberration of CRTC1 expression and/or phosphorylation activity might play a vital role in PS-induced depression-like behavior of offspring rats.

Abstract
Rhynchophylline (RP), the primary active ingredient of Uncaria rhynchophylla, has an anti-hypertensive effect and protects against ischemia-induced neuronal damage. The present study aimed to examine the roles and mechanisms of RP in myocardial ischemia-reperfusion (MI/R) injury of rat cardiomyocytes. Cell viability, reactive oxygen species, mitochondrial membrane potential (MMP) and cell apoptosis were examined by a Cell Counting Kit-8 assay and flow cytometry, respectively. An ELISA was performed to assess the expression of oxidative stress markers. Spectrophotometry was used to detect the degree of mitochondrial permeability transition pore (mPTP) openness. Western blotting and reverse transcription- quantitative polymerase chain reaction assays were used to evaluate the associated protein and mRNA expression, respectively. The present results demonstrated that RP increased the cell viability of MI/R-induced cardiomyocytes, and suppressed the MI/R-induced apoptosis of cardiomyocytes. Additionally, RP modulated the Ca2+ and MMP levels in MI/R-induced cardiomyocytes. Furthermore, RP decreased the oxidative stress and mPTP level of MI/R-induced cardiomyocytes. It was additionally observed that RP affected the apoptosis-associated protein expression and regulated the mitochondrial-associated gene expression in MI/R-induced cardiomyocytes. In conclusion, RP ameliorated MI/R injury through the modulation of mitochondrial mechanisms. The potential effects of RP on the protection of MI/R-induced apoptosis of cardiomyocytes suggest that RP may be an effective target for MI/R therapy.

Involvement of SNARE complex in the hippocampus and prefrontal cortex of offspring with depression induced by prenatal stress. J Affect Disord 2018; 235:374-383. [PMID: 29674253 DOI: 10.1016/j.jad.2018.04.053] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Revised: 03/20/2018] [Accepted: 04/04/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND Prenatal stress (PS) exposure can cause depression-like behavior in offspring, and maladaptive responses including physiological and neurobiological changes. Glutamate neurotransmission is implicated in effects of PS and in antidepressant mechanisms; however, the mechanisms underlying its involvement remain unclear. In the synapse, the formation of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex is essential for vesicular docking and neurotransmitter release. METHODS To explore effects of PS on the SNARE complex, pregnant rats were assigned to a control or PS group. Both male and female offspring in each group were used in this study. PS rats were exposed to restraint stress three times daily for 45 min on days 14-20 of pregnancy. RESULTS In the PS offspring, the expression of the SNARE protein SNAP-25, vesicle-associated membrane protein (VAMP)-2, and Syntaxin 1a was significantly increased in the hippocampus and prefrontal cortex. These observations were associated with increased levels of proteins that chaperone SNARE complex formation, including Munc-18, α-synuclein, CSPα, complexin1, and complexin2. Immunoblotting of hippocampal and prefrontal cortex homogenates revealed significantly increased SNARE complex formation. vGluT1 protein expression was also significantly increased in the offspring. Additionally, PS was associated with increased mRNA expression of VAMP1, VAMP2, SNAP25, Syntaxin1a, and Syntaxin1b in the hippocampus and prefrontal cortex. Increased monomeric SNARE proteins, SNARE complex formation, vesicle-associated proteins, and vGluT1 may explain the increase in glutamate and its downstream excitotoxicity. CONCLUSIONS These results support the hypothesis that glutamate release and vesicular glutamate transporters play a role in PS-induced depression-like behavior of rat offspring.

Abstract
Previous studies have reported that maternal chronic stress or depression is linked to an increased risk of affective disorders in progeny. However, the impact of maternal chronic stress before pregnancy on the progeny of animal models is unknown. We investigated the behaviors and the neurobiology of 60-day-old male offspring of female rats subjected to 21 days of resident-intruder stress before pregnancy. An anger stressed parental rat model was established using the resident-intruder paradigm and it was evaluated using behavioral tests. Anger stressed maternal rats showed a significant increase in locomotion and aggression but a reduction in sucrose preference. Offspring subjected to pre-gestational anger stress displayed enhanced aggressive behaviors, reduced anxiety, and sucrose preference. Further, offspring subjected to pre-gestational stress showed significant impairments in the recognition index (RI) on the object recognition test and the number of platform crossings in the Morris water maze test. The monoaminergic system was significantly altered in pre-gestationally stressed offspring, and the expression of phosphorylated cyclic adenosine monophosphate response element binding protein (P-CREB), brain-derived neurotrophic factor (BDNF), and serotonin transporter (SERT) levels in pre-gestational stressed offspring were altered in some brain regions. Fluoxetine was used to treat pre-gestational stressed maternal rats and it significantly reduced the changes caused by stress, as evidenced by both behaviors and neural biochemical indexes in the offspring in some but not all cases. These findings suggest that anger stress before pregnancy could induce aggressive behaviors, cognitive deficits, and neurobiological alterations in offspring.

Abstract
Stress during pregnancy is a known contributing factor for the development of obesity in the offspring. Since maternal obesity is on the rise, we wanted to identify the effects of prenatal stress in the offspring of diet-induced obese (DIO) rats and compare them with the offspring of dietary-resistant (DR) rats. We hypothesized that prenatal stress would make both DIO and DR offspring susceptible to obesity, but the effect would be more pronounced in DIO rats. Pregnant DIO and DR rats were divided into two groups: nonstressed controls (control) and prenatal stress (subjected to restraint stress, three times/day from days 14 to 21 of gestation). After recording birth weight and weaning weight, male offspring were weaned onto a chow diet for 9 wk and shifted to a high-fat (HF) diet for 1 wk. At the end of the 10th wk the animals were euthanized, and visceral adipose mass, blood glucose, serum insulin, and C-peptide levels were measured. Prenatal stress resulted in hyperinsulinemia and higher C-peptide levels without altering caloric intake, body weight gain, or fat mass in the DIO offspring after 1 wk of HF intake, but not in DR offspring. To determine the mechanism underlying the hyperinsulinemia, we measured the levels of CEACAM1 that are responsible for insulin clearance. CEACAM1 levels in the liver were reduced in prenatally stressed DIO offspring after the HF challenge, suggesting that preexisting genetic predisposition in combination with prenatal stress increases the risk for obesity in adulthood, especially when offspring are fed a HF diet.

Abstract
The purpose of the present study was to characterize the expressions of phosphorylated Ca(2+)/calmodulin-dependent protein kinase II (p-CaMK-II), total CaMK-II, and L-type Ca(2+) channel in offspring hippocampus that was induced by prenatal restraint stress. Pregnant rats were divided into two groups: the control group and the prenatal stress (PNS) group. Pregnant rats in the PNS group were exposed to restraint stress on day 14-20 of pregnancy three times daily for 45 min. Adult offspring rats were used in this study. The results demonstrated that prenatal restraint stress induced a significant increase in the expression of p-CaMK-II, total CaMK-II, and L-Ca(2+) channel by western blot analysis in offspring hippocampus. The immunohistochemistry results revealed that PNS increased the expressions of CaMK-II and L-Ca(2+) channel in the hippocampal CA3 of offspring rats. These data suggest that PNS can have long-term neuronal effects within hippocampal structure involved in the feedback mechanisms of the hypothalamo-pituitary-adrenal axis.

Abstract
Lycium barbarum (Fructus Lycii, Wolfberry, or Gouqi) belongs to the Solanaceae. The red-colored fruits of L. barbarum have been used for a long time as an ingredient in Chinese cuisine and brewing, and also in traditional Chinese herbal medicine for improving health. However, its effects on cognitive function have not been well studied. In the present study, prevention of a milk-based wolfberry preparation (WP) on cognitive dysfunction was tested in a prenatal stress model with rats and the antioxidant mechanism was tested by in vitro experiments. We found that prenatal stress caused a significant decrease in cognitive function (Morris water maze test) in female offspring. Pretreatment of the mother rats with WP significantly prevented the prenatal stress-induced cognitive dysfunction. In vitro studies showed that WP dose-dependently scavenged hydroxyl and superoxide radicals (determined by an electron spin resonance spectrometric assay), and inhibited FeCl(2)/ascorbic acid-induced dysfunction in brain tissue and tissue mitochondria, including increases in reactive oxygen species and lipid peroxidation and decreases in the activities of complex I, complex II, and glutamate cysteine ligase. These results suggest that dietary supplementation with WP may be an effective strategy for preventing the brain oxidative mitochondrial damage and cognitive dysfunction associated with prenatal stress.

Abstract
2',2',3',3',4',4',5',5',6',6',-decabrominated diphenyl ether (PBDE-209) is the most widely used polybrominated diphenyl ethers (PBDEs) globally. Some animal experiments have found that PBDE-209 caused developmental neurotoxicity. But detailed mechanisms are less well understood. Our experiments were conducted to research the potential neurotoxic mechanisms of PBDE-209 in primary cultured neonatal rat hippocampal neurons by measuring cell viability, apoptotic rate, expression of P38 mitogen-activated protein kinases (MAPKs), calcium ion concentration, oxidative stress, nitrous oxide (NO) content, and global gene DNA methylation levels. The neurons were exposed to different PBDE-209 concentrations (0, 10, 30 and 50 microg/ml). The difference between the experimental groups and control groups was significant (P<0.05). PBDE-209 increased the rate of apoptosis, expression of P38 MAPK, calcium ion concentration, reactive oxygen species (ROS) level, malondialdehyde (MDA) content and NO content (P<0.05). In addition, PBDE-209 deceased cell viability, activity of superoxide dismutase (SOD) and the levels of global gene DNA methylation (P<0.05). The results suggested that PBDE-209 could affect secondary messengers, cause oxidative stress and decrease global gene DNA methylation levels. These actions may contribute to the mechanism of PBDE-209 neurotoxicity.
