Abstract
Alzheimer's disease (AD) is a common age-related neurodegenerative disease characterized by progressive cognitive decline and irreversible memory impairment. Currently, several studies have failed to fully elucidate AD's cellular and molecular mechanisms. For this purpose, research on related cellular models may propose potential predictive models for the drug development of AD. Therefore, many cells characterized by neuronal properties are widely used to mimic the pathological process of AD, such as PC12, SH-SY5Y, and N2a, especially the PC12 pheochromocytoma cell line. Thus, this review covers the most systematic essay that used PC12 cells to study AD. We depict the cellular source, culture condition, differentiation methods, transfection methods, drugs inducing AD, general approaches (evaluation methods and metrics), and in vitro cellular models used in parallel with PC12 cells.

Abstract
Objectives: Cholinergic system dysfunction was found to play a key role in Alzheimer's disease (AD) pathogenesis. Therefore, the animal model of scopolamine-induced amnesia has been widely used in AD researches. Cinnamon, as a spice commonly used in cuisine, has been shown to exert some therapeutic effects. The most abundant compound in cinnamon is cinnamaldehyde which recently was shown to exert several neuroprotective effects in animal models. Therefore, this study aimed to assess whether cinnamaldehyde has the potency to prevent memory retrieval impairment and hippocampal protein kinase B (Akt) and MAPK (extracellular signal-regulated kinase (ERK)) alterations induced by scopolamine in mice.Methods: Adult male mice were pretreated with cinnamaldehyde (12.5, 25, 40 and 100 mg/kg/oral gavage) 10 days before training. The training of passive avoidance task was performed on the 10th day and a memory retention test was done 24 h later. Scopolamine (1 mg/kg) was injected intraperitoneally, 30 min before the retention test to induce memory retrieval deficit. At the complement of the behavioral experiments, the hippocampi were isolated for western blot analysis to assess the phosphorylated and total levels of hippocampal MAPK and Akt proteins.Results: The results showed that cinnamaldehyde pretreatment at the dose of 100 mg/kg significantly prevented the amnesic effect of scopolamine. Furthermore, cinnamaldehyde prevented scopolamine induced dysregulations of hippocampal MAPK and Akt.Discussion: The results of the present study revealed that oral sub-chronic cinnamaldehyde administration has the capability to prevent memory retrieval deficit induced by cholinergic blockade and restores hippocampal MAPK and Akt dysregulations.

Abstract
Bipolar disorder (BD) is a severe and common chronic mental illness characterized by recurrent mood swings between depression and mania. The biological basis of the disease is poorly understood and its treatment is unsatisfactory. Although in past decades the "monoamine hypothesis" has dominated our understanding of both the pathophysiology of depressive disorders and the action of pharmacological treatments, recent studies focus on the involvement of additional neurotransmitters/neuromodulators systems and cellular processes in BD. Here, evidence for the participation of Na⁺, K⁺-ATPase and its endogenous regulators, the endogenous cardiac steroids (ECS), in the etiology of BD is reviewed. Proof for the involvement of brain Na⁺, K⁺-ATPase and ECS in behavior is summarized and it is hypothesized that ECS-Na⁺, K⁺-ATPase-induced activation of intracellular signaling participates in the mechanisms underlying BD. We propose that the activation of ERK, AKT, and NFκB, resulting from ECS-Na⁺, K⁺-ATPase interaction, modifies neuronal activity and neurotransmission which, in turn, participate in the regulation of behavior and BD. These observations suggest Na⁺, K⁺-ATPase-mediated signaling is a potential target for drug development for the treatment of BD.

Abstract
The release of nanoparticles (NPs) into the ocean inevitably poses a threat to marine organisms. However, to date, the neurotoxic effects of NPs remains poorly understood in marine bivalve species. Therefore, in order to gain a better understanding of the physiological effects of NPs, the impact of acute (96 h) TiO2 NP exposure on the in vivo concentrations of three major neurotransmitters, the activity of AChE, and the expression of neurotransmitter-related genes was investigated in the blood clam, Tegillarca granosa. The obtained results showed that the in vivo concentrations of the three tested neurotransmitters (DA, GABA, and ACh) were significantly increased when exposed to relatively high doses of TiO2 NPs (1 mg/L for DA and 10 mg/L for ACh and GABA). Additionally, clams exposed to seawater contaminated with TiO2 NP had significantly lower AChE activity. In addition, the expression of genes encoding modulatory enzymes (AChE, GABAT, and MAO) and receptors (mAChR3, GABAD, and DRD3) for the neurotransmitters tested were all significantly down-regulated after TiO2 NP exposure. Therefore, this study has demonstrated the evident neurotoxic impact of TiO2 NPs in T. granosa, which may have significant consequences for a number of the organism's physiological processes.

Abstract
The Src family kinase (SFK) is a subfamily of non-receptor tyrosine kinases. SFK members, Src and especially Fyn, are expressed in the striatum. These SFK members are involved in the regulation of neuronal and synaptic activities and are linked to the pathogenesis of a variety of neuropsychiatric and neurodegenerative disorders. Given the fact that muscarinic acetylcholine (mACh) receptors are highly expressed in striatal neurons and are critical for the regulation of striatal function, we investigated the role of mACh receptors in the regulation of SFKs in the adult rat striatum in vivo. We found that pharmacological blockade of mACh receptors by systemic administration of the mACh antagonist scopolamine induced a marked increase in phosphorylation of SFKs in the striatum of male and female rats. This scopolamine-induced increase in SFK phosphorylation occurred in the two subdivisions of the striatum (caudate putamen and nucleus accumbens) and was time-dependent and reversible. Another mACh antagonist atropine was also effective in stimulating SFK phosphorylation. Coadministration of subthreshold doses of scopolamine and a dopamine D1 receptor agonist SKF81297 enhanced striatal SFK phosphorylation. Between Fyn and Src proteins immunoprecipitated from striatal tissue, scopolamine selectively increased phosphorylation of Fyn. The increase in Fyn phosphorylation was accompanied by an increase in Fyn kinase activity in response to scopolamine. These results reveal a significant role of mACh receptors in the regulation of SFKs (mainly Fyn) in striatal neurons. Under normal conditions, endogenous mACh receptors appear to exert an inhibitory effect on Fyn activity.

Scopolamine-induced passive avoidance memory retrieval deficit is accompanied with hippocampal MMP2, MMP-9 and MAPKs alteration. Eur J Pharmacol 2017; 819:248-253.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive loss of memory and cognitive deficit. The observed amnesia in the early stages of AD is suggested to be a retrieval problem, rather than encoding and consolidation deficit. According to the cholinergic hypothesis of AD, scopolamine is used to induce an animal model of amnesia. Howbeit the effect of scopolamine on memory retrieval is contradictory. This study aimed to assess the effect of scopolamine on passive avoidance memory retrieval. Additionally according to the reported changes of MMP-2, MMP-9 and MAPKs (ERK, P38 and JNK) in AD pathology the hippocampal contents of these proteins were determined. Male NMRI mice weighing 20-25g were trained in passive avoidance apparatus. The drug or its vehicle was injected 24h after training (30min before retention test). The hippocampal tissue was isolated and western blot analysis was done for MMP-2, MMP-9 and MAPKs (ERK, P38 and JNK). The results indicated that scopolamine (1mg/kg) disrupts passive avoidance memory retrieval. This scopolamine treatment resulted in hippocampal MMP-2 and MMP-9 decline while increased MAPKs in the hippocampus. These results suggest that cholinergic system has an important role in learnt memory retrieval. It might also suggest the positive role of MMP-2 and MMP-9 in this phase of memory while propose that MAPKs affect negatively the reactivation of memory which is compatible with MAPKs activation in AD.
