Abstract
AIM This study aims to explore the similarity and difference of hippocampal miRNAomes between humans and mice. MATERIALS & METHODS A systematic comparison of the miRNAomes between healthy human and mouse hippocampi was performed using high-throughput sequencing followed by bioinformatic analyses. RESULTS A novel miRNA termed novel-21-5p and a human-specific miR-656-3p were identified in human hippocampi, which were expressed ubiquitously and predicted to be associated with neural activities. Compared with mouse, abundantly expressed miRNAs in human hippocampus were notably enriched in pathways pertaining to neural activities, such as neurotrophin TRK receptor signaling pathway, axon guidance and synaptic transmission. Expression pattern of orthologous miRNAs between human and mouse hippocampi was conserved. Meanwhile, the expression conservation was positively correlated with the sequence conservation. CONCLUSION Hippocampal miRNAomes between humans and mice were overall comparable; the differences in expression or function across species should be considered when constructing mouse models.

Abstract
Protein tyrosine phosphorylation is one of the primary modes of regulation of N-methyl-d-aspartate (NMDA) receptors. The non-receptor tyrosine kinases are one of the two types of protein tyrosine kinases that are involved in this process. The overactivation of NMDA receptors is a primary reason for neuron death following cerebral ischemia. Many studies have illustrated the important role of non-receptor tyrosine kinases in ischemia insults. This review introduces the roles of Src, Fyn, focal adhesion kinase, and proline-rich tyrosine kinase 2 in the excitotoxicity induced by the overactivation of NMDA receptors following cerebral ischemia.

Apoptotic protein profile in Leishmania donovani after treatment with hexaazatrinaphthylenes derivatives. Exp Parasitol 2016; 166:83-8. [PMID: 27060614 DOI: 10.1016/j.exppara.2016.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 03/31/2016] [Accepted: 04/05/2016] [Indexed: 10/22/2022]
Abstract
Two hexaazatrinaphthylene derivatives, DGV-B and DGV-C previously known to induce an apoptotic-like process in Leishmania donovani parasites were used in this study. For this purpose, two different human protein commercial arrays were used to determine the proteomic profile of the treated parasites compared to non-treated ones. One of the commercial arrays is able to detect the relative expression of 35 human apoptosis-related proteins and the other one is able to identify 9 different human kinases. The obtained results showed that the two tested molecules were able to activate a programmed cell death process by different pathways in the promastigote stage of the parasite. The present study reports the potential application of two commercialised human apoptotic arrays to evaluate the action mechanism of active compounds at least against Leishmania donovani. The obtained data would be useful to establish the putative activated apoptosis pathways in the treated parasites and to further support the use of hexaazatrinaphthylene derivatives for the treatment of leishmaniasis in the near future. Nevertheless, further molecular studies should be developed in order to design and evaluate specific apoptotic arrays for Leishmania genus.

Imipramine administration induces changes in the phosphorylation of FAK and PYK2 and modulates signaling pathways related to their activity. Biochim Biophys Acta Gen Subj 2015; 1860:424-33.

Abstract
BACKGROUND Antidepressants can modify neuronal functioning by affecting many levels of signal transduction pathways that are involved in neuroplasticity. We investigated whether the phosphorylation status of focal adhesion kinase (FAK/PTK2) and its homolog, PYK2/PTK2B, and their complex with the downstream effectors (Src kinase, p130Cas, and paxillin) are affected by administration of the antidepressant drug, imipramine. The treatment influence on the levels of ERK1/2 kinases and their phosphorylated forms (pERK1/2) or the Gαq, Gα11 and Gα12 proteins were also assessed. METHODS Rats were injected with imipramine (10 mg/kg, twice daily) for 21 days. The levels of proteins investigated in their prefrontal cortices were measured by Western blotting. RESULTS Imipramine induced contrasting changes in the phosphorylation of FAK and PYK2 at Tyr397 and Tyr402, respectively. The decreased FAK phosphorylation and increased PYK2 phosphorylation were reflected by changes in the levels of their complex with Src and p130Cas, which was observed predominantly after chronic imipramine treatment. Similarly only chronic imipramine decreased the Gαq expression while Gα11 and Gα12 proteins were untouched. Acute and chronic treatment with imipramine elevated ERK1 and ERK2 total protein levels, whereas only the pERK1 was significantly affected by the drug. CONCLUSION The enhanced activation of PYK2 observed here could function as compensation for FAK inhibition. GENERAL SIGNIFICANCE These data demonstrate that treatment with imipramine, which is a routine in counteracting depressive disorders, enhances the phosphorylation of PYK2, a non-receptor kinase instrumental in promoting synaptic plasticity. This effect documents as yet not considered target in the mechanism of imipramine action.

Abstract
Focal adhesion kinase (FAK) and proline-rich tyrosine kinase (PYK2) are two related non-receptor tyrosine kinases which are thought to play a role in transducing extracellular matrix (ECM)-derived survival signals into cells. The functions of FAK and PYK2 are linked to autophosphorylation of their specific tyrosine residues, Tyr-397 in FAK and Tyr-402 in PYK2, and then association with different signalling proteins which mediate activation of downstream targets such as ERK and JNK mitogen-activated kinase cascades. Thus, modulation of FAK as well as PYK2 autophosphorylation may affect several intracellular pathways and may participate in a variety of pathological settings. The present study provides a systematic investigation of the influence of experimental ischemia, induced by oxygen-glucose-deprivation, on the FAK- and PYK2-mediated signalling in organotypic hippocampal slice cultures. OGD induced primary down-regulation of FAK and PYK2 autophosphorylation (at Tyr 397 and Tyr 402, respectively) at 24-48 h of reoxygenation was accompanied by the diminution of phosphorylation/activation of Src and JNK. In contrast, the activity of Akt and ERK1/2 remained on the control level. It indicates that Akt kinase as well as ERK1/2 does not interfere with OGD-induced neuronal damage. The inhibition of the early step of FAK and PYK2 activation demonstrated by the decrease of tyrosine autophosphorylation may comprise an important portion of the response expressed by modulation of some coupled signal transduction pathways.

Abstract
Tau phosphorylation is regulated by a balance between tau kinase and phosphatase activities. Disruption of this equilibrium was suggested to be at the origin of abnormal tau phosphorylation and thereby might contribute to tau aggregation. Thus, understanding the regulation modes of tau phosphorylation is of high interest in determining the possible causes at the origin of the formation of tau aggregates in order to elaborate protection strategies to cope with these lesions in Alzheimer's disease. Among the possible and specific interventions that reverse tau phosphorylation is the inhibition of certain tau kinases. Here, we extensively reviewed tau protein kinases, their physiological roles and regulation, their involvement in tau phosphorylation and their relevance to AD. We also reviewed the most common inhibitory compounds acting on each tau kinase.

Abstract
Src family of kinases (SFKs) and focal adhesion kinase (FAK) are two important cellular signaling components known to act cooperatively in the transduction of death and survival signals. We investigated the involvement of these proteins in the mechanism of the injurious response in rat primary neuronal cultures exposed to an insult composed of chemical ischemia (poisoning with iodoacetic acid; 100 muM, for 150 min) followed by 1 h of incubation in the regular medium, an insult shown before to be associated with generation of reactive oxygen species and with the depletion of adenosine triphisphate. The exposure of the neuronal cultures to the insult resulted in cell injury, assessed by the increased release of cytoplasmic lactate dehydrogenase (LDH) into the culture media, which could be attenuated markedly by the presence of the antioxidant LY 231617. The insult resulted in the decreased level of phosphorylation of the SFKs members Src, Fyn, and Yes at the Src Y416-equivalent activation sites and of the FAK Y397 activation site, degradation of FAK to a p85 fragment, and disassembling of the FAK-SFKs complexes. The inhibition of SFKs was found to be responsible for part of the insult-induced cell damage manifested in increased LDH release. Pervanadate, an inhibitor of the phosphotyrosine phosphatases (PTPs), abrogated the inactivation of SFKs and attenuated cell injury, indicating that insult-induced activation of PTPs is involved in SFKs inhibition and the ensued damage. The inhibition of SFKs and FAK is probably the cause of the disassembling of SFKs-FAK complexes, a process known to be associated with apoptosis.
