Abstract
Chronic unpredictable mild stress (CUMS) method has been introduced as a rodent model of depression. On the other hand, olanzapine, as an antipsychotic, can induce antidepressant and antipsychotic effects. Also, olanzapine may improve cognitive functions. Both CUMS and olanzapine can also affect the expression level of brain-derived neurotrophic factor (BDNF) and synaptophysin, the molecular factors involved in synaptic function, and learning and memory. In this study, we investigated the effect of olanzapine on locomotor activity (using open field test), pain threshold (using hot plate), depressive-like behavior (using forced swim test), spatial learning and memory (using Morris water maze), and BDNF and synaptophysin hippocampal expression (using real-time PCR) in both male and female CUMS rats. CUMS was performed for three consecutive weeks. Olanzapine was also injected intraperitoneally at the dose of 5 mg/kg. Our data showed that olanzapine can reverse the effects of CUMS on behavioral functions and BDNF and synaptophysin expression levels in the hippocampus of both males and females. It was also shown that olanzapine effects on spatial memory, pain perception, and BDNF and synaptophysin level were stronger in females than males. In conclusion, we suggested that the therapeutic effects of olanzapine in CUMS rats may be closely related to the function of BDNF and synaptophysin. Also, the therapeutic effects of olanzapine may be stronger in females. Therefore, and for the first time, we showed that there may be a sex difference in the effects of olanzapine on behavioral and molecular changes following CUMS.

The effect of crocin on cholestasis-induced spatial memory impairment with respect to the expression level of TFAM and PGC-1α and activity of catalase and superoxide dismutase in the hippocampus. Metab Brain Dis 2023; 38:1167-1176.

Abstract
Large evidence has shown that cholestasis has a wide-range of deleterious effects on brain function, and also, on neurocognitive functions including learning and memory. On the other hand, crocin (derived from Crocus sativus) is a medicinal natural compound that induces neuroprotective and precognitive effects. In this study, we aimed to evaluate the effect of crocin on spatial learning and memory in cholestatic rats with respect to the level of mitochondrial transcriptional factor A (TFAM), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), catalase (CAT), and superoxide dismutase (SOD) in the hippocampus of male Wistar rats. Bile duct ligation (BDL) was used to induce cholestasis. Y-maze apparatus was used to assess spatial memory performance and real-time PCR was used to assess TFAM and PGC-1α gene expression. Also, crocin was injected intraperitoneal at the doses of 15, 20, and 30 mg/kg for thirty days. The results showed that BDL impaired spatial memory in rats. BDL also decreased SOD, TFAM, and PGC-1α level. In addition, crocin partially reversed the impairment effect of BDL on spatial memory. Crocin (30 mg/kg) also reversed the effect of BDL on SOD, TFAM, and PGC-1α. Of note, the effect of BDL on CAT activity was controversial. It seems that BDL can increase CAT activity. In addition, crocin (30 mg/kg) reversed the enhancement of CAT following BDL to its control level. In conclusion, crocin may induce a significant neuroprotective effect on cholestasis-induced memory impairment.

The Interaction Effect of Sleep Deprivation and Treadmill Exercise in Various Durations on Spatial Memory with Respect to the Oxidative Status of Rats. Neurochem Res 2023; 48:2077-2092. [PMID: 36786943 DOI: 10.1007/s11064-023-03890-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 02/02/2023] [Accepted: 02/04/2023] [Indexed: 02/15/2023]
Abstract
Sleep deprivation (SD) has deleterious effects on cognitive functions including learning and memory. However, some studies have shown that SD can improve cognitive functions. Interestingly, treadmill exercise has both impairment and improvement effects on memory function. In this study, we aimed to investigate the effect of SD for 4 (short-term) and 24 (long-term) hours, and two protocols of treadmill exercise (mild short-term and moderate long-term) on spatial memory performance, and oxidative and antioxidant markers in the serum of rats. Morris Water Maze apparatus was used to assess spatial memory performance. Also, SD was done using gentle handling method. In addition, the serum level of catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) was measured. The results showed that 24 h SD (but not 4 h) had negative effect on spatial memory performance, decreased SOD, CAT, and GSH-Px level, and increased MDA level. Long-term moderate (but not short-term mild) treadmill exercise had also negative effect on spatial memory performance, decreased SOD, CAT, and GSH-Px level, and increased MDA level. Interestingly, both protocols of treadmill exercise reversed spatial memory impairment and oxidative stress induced by 24 h SD. In conclusion, it seems that SD and treadmill exercise interact with each other, and moderate long-term exercise can reverse the negative effects of long-term SD on memory and oxidative status; although, it disrupted memory function and increased oxidative stress by itself.

Abstract
Neurosteroids are apparent to be connected in the cerebral ischemic injury for their potential neuroprotective effects. We previously demonstrated that progesterone induces neuroprotection via the mitochondrial cascade in the cerebral ischemic stroke of rodents. Here, we sought to investigate whether or not pregnenolone, a different neurosteroid, can protect the ischemic injury in the transient middle cerebral artery occlusion (tMCAO) rodent model. Male Wistar rats were chosen for surgery for inducing stroke using the tMCAO method. Pregnenolone (2 mg/kg b.w.) at 1 h postsurgery was administered. The neurobehavioral tests and (TTC staining) 2, 3, 5-triphenyl tetrazolium chloride staining were performed after 24 h of the surgery. The mitochondrial membrane potential and reactive oxygen species (ROS) were measured using flow cytometry. Oxygraph was used to examine mitochondrial bioenergetics. The spectrum of neurobehavioral tests and 2, 3, 5-triphenyltetrazolium chloride staining showed that pregnenolone enhanced neurological recovery. Pregnenolone therapy after a stroke lowered mitochondrial ROS following ischemia. Our data demonstrated that pregnenolone was not able to inhibit mitochondrial permeability transition pores. There was no effect on mitochondrial bioenergetics such as oxygen consumption and respiratory coupling. Overall, the findings demonstrated that pregnenolone reduced the neurological impairments via reducing mitochondria ROS but not through the inhibition of the mitochondria permeability transition pore (mtPTP).
