Studying the Brain Monoaminergic Systems and Neurotrophic Factors in Minipigs with High and Low Tolerance to the Presence of Human.

Here, we present the first evidence for brain adaptation in pigs tolerant to the human presence, as a behavioral trait favoring domestication. The study was carried out on minipiglets from population bred at the Institute of Cytology and Genetics (Novosibirsk, Russia). We compared the behavior, metabolism of monoaminergic neurotransmitter systems, and functional activity of the hypothalamic-pituitary-adrenal system, as well as neurotrophic markers in the brain of minipigs differing by tolerance to human presence (HT and LT - high and low tolerance).

[Zbtb33 Gene Knockout Changes Transcription of the Fgf9, Fgfr3, с-Мус and FoxG1 Genes in the Developing Mouse Brain].

The transcription factor KAISO is important for proper development of animal embryos. In the cell, KAISO regulates cell division and apoptosis. KAISO is abundant in the central nervous system.

'Trojan-Horse' stress-granule formation mediated by manganese oxide nanoparticles.

Exposure to nanomaterials is considered as one of the risk factors for neurodegenerative pathology. inorganic nanoparticles (NPs) absorb intrinsically disordered proteins, many of which are the constituents of stress-granules (SGs). SGs normally form in response to cellular stress and, here, we addressed whether selected inorganic NPs could trigger SGs formation in cells.

Inhibitor of Striatal-Enriched Protein Tyrosine Phosphatase, 8-(Trifluoromethyl)-1,2,3,4,5-Benzopentathiepin-6-Amine hydrochloride (TC-2153), Produces Antidepressant-Like Effect and Decreases Functional Activity and Protein Level of 5-HT Receptor in the Brain.

The serotoninergic 5-HT receptor is involved in the mechanism of depression and antidepressant drugs action. Earlier we showed that striatal-enriched protein tyrosine phosphatase (STEP) inhibitor - 8-(trifluoromethyl)-1,2,3,4,5-benzopentathiepin-6-amine hydrochloride (TC-2153) affects both the brain serotoninergic system and the brain-derived neurotropic factor that are known to be involved in the psychopathology of depression. In the present study we investigated the effects of chronic TC-2153 administration on behavior in the standard battery of tests as well as the effects of acute and chronic TC-2153 treatment on the brain 5-HT receptors in mice.

Effects of a compound from the group of substituted thiadiazines with hypothermia inducing properties on brain metabolism in rats, a study in vivo and in vitro.

The aim of the present study was to examine how administration of a compound of 1,3,4- thiadiazine class 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine, hydrobromide (L-17) with hypothermia inducing properties affects the brain metabolism. The mechanism by which L-17 induces hypothermia is unknown; it may involve hypothalamic central thermoregulation as well as act via inhibition of energy metabolism. We tested the hypothesis that L-17 may induce hypothermia by directly inhibiting energy metabolism.
