Abstract
We performed a comparative in vitro study of the involvement of NF-κB, PI3K, cAMP, ERK1/2, p38, JAKs, STAT3, JNK, and p53-dependent intracellular signaling in the functioning of neural stem cells (NSC) under the influence of basic fibroblast growth factor (FGF) and FGF receptor agonist, diterpene alkaloid songorine. The significant differences in FGFR-mediated intracellular signaling in NSC were revealed for these ligands. In both cases, stimulation of progenitor cell proliferation occurs with the participation of NF-κB, PI3K, ERK1/2, JAKs, and STAT3, while JNK and p53, on the contrary, inhibit cell cycle progression. However, under the influence of songorin, cAMP- and p38-mediated cascades are additionally involved in the transmission of the NSC division-activating signal. In addition, unlike FGF, the alkaloid stimulates progenitor cell differentiation by activating ERK1/2, p38, JNK, p53, and STAT3.

Abstract
We studied the effect of JNK and p53 inhibitors on the production of neurotrophic factors stimulating the realization of the growth potential of neural stem cells by neuroglial cells of various types under conditions of simulation of induced β-amyloid neurodegeneration in vitro. It was shown that β-amyloid stimulates the production of neurotrophins by astrocytes and microglial cells, but does not affect the functioning of oligodendrocytes. JNK and p53 were not involved in the secretion of neurotrophins by intact astrocytes. The stimulating role of p53 on the implementation of their secretory activity under the influence of a neurotoxic agent was revealed. At the same time, the inhibitory role of JNK and p53 in the production of neurotrophic growth factors by oligodendrocytes and microglial cells was revealed both under conditions of their optimal vital activity and when β-amyloid was added to the cell culture.

Abstract
Under conditions of neurodegeneration modeled in vitro by the β-amyloid peptide-(25-35) fragment (Aβ25-35), we studied the role of individual links of cAMP-dependent intracellular signaling pathways in determining the proliferation and differentiation status of neural stem cells (NSCs) and colony-stimulating activity of supernatants from neuroglial cells. The important role of intracellular cAMP and PKA in the inhibition of the progression of the NSC cell cycle and stimulation of the process of their specialization induced by Aβ25-35 was found. The selective ability of PKA to block the production of factors constituting colony-stimulating activity by neuroglial cells under conditions of their cultivation in vitro with a neurotoxic agent was revealed. Our results suggests that inhibitors of adenylate cyclase and PKA can increase the degree of implementation of the growth potential of NSCs and conjugation of the processes of their proliferation and differentiation in Alzheimer's disease. At the same time, selective PKA blockers can also induce the production of NSC-stimulating factors by neuroglial cells.

Abstract
We studied the involvement of cAMP and PKA in the regulation of the secretion of neurotrophic growth factors by macro-and microglial cells in the model of ethanol-induced neurodegeneration in vitro and in vivo. The stimulating role of cAMP in the secretion of neurotrophins by intact astrocytes and oligodendrocytes was shown, while PKA does not participate in this process. On the contrary, the inhibitory role of cAMP (implemented via PKA activation) in the production of neurogenesis stimulators by microglial cells under conditions of optimal vital activity was found. Under the influence of ethanol, the role of cAMP and PKA in the production of growth factors by macroglial cells was considerably changed. The involvement of PKA in the cAMP-dependent signaling pathways and inversion of the role of this signaling pathway in the implementation of the neurotrophic secretory function of astrocytes and oligodendrocytes, respectively, directly exposed to ethanol in vitro were noted. Long-term exposure of the nervous tissue to ethanol in vivo led to the loss of the stimulating role of cAMP/PKA signaling on neurotrophin secretion by macroglial cells without affecting its inhibitory role in the regulation of this function in microglial cells.

Abstract
The psychopharmacological effects of a stimulator of functions of progenitor cells of the nervous tissue STAT3 inhibitor (STAT3 Inhibitor XIV, LLL12) were studied under conditions of modeled alcoholic encephalopathy in C57BL/6 mice. The pharmacological agent corrected the parameters of exploratory behavior (characterizing predominantly cognitive activity) in the experimental animals at the late terms of observation. At the same time, the reproducibility of the conditioned passive avoidance response developed at the beginning of the course STAT3 inhibitor administration decreased. These effects developed against the background of a significant increase in the content of neural stem cells and their proliferative activity in the paraventricular zone of the brain.

Abstract
The effects of JAK and STAT3 inhibitors on the production of neurotrophic growth factors by different types of neuroglial cells were studied under conditions of in vitro and in vivo models of ethanol-induced neurodegeneration. It was shown that these signaling molecules do not participate in the secretion of neurotrophins by intact astrocytes and oligodendrocytes. The inhibitory role of JAK in the regulation of this function of microglial cells was revealed. We also revealed significant changes in the role of JAK and the presence of STAT3 specifics within the framework of JAK/STAT signaling in the production of growth factors by various glial elements under the influence of ethanol. Neurodegeneration modeled in vitro led to the appearance of a "negative" effect of STAT3 on the production of neurogenesis stimulants by all types of glial cells. Moreover, the role of STAT3 in oligodendrocytes and microglial cells generally corresponded to that of JAK/STAT signaling. In astrocytes, only selective blockade of STAT3 (but not JAK) led to stimulation of their function. In mice subjected to prolonged peroral alcoholization, the neuroglial responses to the pharmacological regulation of JAK/STAT signaling were different. An inversion of the role of JAK and STAT3 in the production of neurotrophins by oligodendrocytes was noted. In addition, JAK inhibitor did not stimulate secretory function of microglial cells under conditions of prolonged exposure to ethanol in vivo.

Abstract
Under conditions of steady-state hemopoiesis, nuclear factor NF-κB, in contrast to MAP kinase p38, plays an important role in the maintenance of the initial level of secretory activity of monocytes. The increase in the production of G-CSF under stress conditions (10-h immobilization) is mainly regulated by the alternative p38MARK signaling pathway via activation of p38 synthesis. It was shown that under conditions of cytostatic-induced myelosuppression, the production of protein kinase p38 in cells decreases, and it, like NF-κB, is not the main one in the production of hemopoietin by mononuclear phagocytes.

Abstract
We studied the peculiarities of the participation of ERK1/2 and р38 in regulation of various types of progenitor cells of the nervous tissue under conditions of ethanol-induced neurodegeneration modeled in vitro and in vivo. The stimulating role of these signaling molecules in the realization of the growth potential of intact multipotent neural stem cells and committed neuronal precursors (clonogenic PSA-NCAM+ cells) was demonstrated. In vitro exposure to neurotoxic doses of ethanol led to the loss of the specified role of ERK1/2 and p38 in the cell cycle regulation. Inversion of the role of both studied MAP-kinases in determining the proliferation status of neural stem cells after long-term administration of ethanol to experimental animals was revealed. In committed neuronal precursors, this inversion (inhibition of mitotic activity instead of activation) was revealed only for ERK1/2. In mice exposed to chronic alcoholization, ERK1/2 no longer participated in the process of specialization of both types of regeneration-competent cells of the nerve tissue. The revealed fundamental difference between the functions of ERK1/2 and p38 in the cell cycle regulation in neural stem cells and committed neuronal precursors under optimal conditions and during ethanol-induced neurodegeneration does not allow drawing definite conclusions about the prospect of using modifiers of their activity for the therapy for alcohol-related CNS pathologies.

Abstract
Suppression of the production of granulocytic CSF under the effect of 5-fluorouracyl is related to disorders in the NF-κB-, cAMP-dependent signaling pathways and MAPK cascade. These secondary messengers are involved in the regulation of functional activity of nonadherent myelokaryocytes starting from day 10 of the experiment (initial period of the hemopoietic granulocytic stem regeneration after antimetabolite challenge). Granulocytic CSF does not play essential role in the formation of colony-stimulating activity of cells of the adherent and nonadherent fractions of the bone marrow. Only cAMP-dependent pathway is involved in the regulation of the realization of the granulocytic precursor growth potential in response to the challenge.

Abstract
The hemostimulating effects of c-Jun N-terminal kinase (JNK) inhibitor were examined on the mouse model of myelosuppression provoked by 5-fluorouracil. Blockade of JNK during postcytostatic period accelerated recovery of granulomonocytopoiesis and erythropoiesis. It also increased the content of neutrophilic granulocytes and erythroid cells in the hematopoietic tissue and elevated the counts of neutrophils and reticulocytes in the peripheral blood. The development of these phenomena resulted from elevated content and up-regulated functional activity of bone marrow hematopoietic progenitors associated with the direct action of JNK inhibitor on these progenitors and enhanced secretion of hemopoietins by stromal elements of the hematopoiesis-inducing microenvironment.

Abstract
Peculiar roles of JAKs and STAT3 in realization of growth potential of various types of progenitor cells in neural tissue were examined during ethanol-induced neurodegeneration modeled both in vitro and in vivo. During in vitro action of C2H5OH, these signal molecules exerted the opposite effects on mitotic activity of multipotent neural stem cells and committed neural progenitors (the clonogenic PSA-NCAM+ cells). The JAKs and STAT3 inhibitors down-regulated the rate of neural stem cell division (proliferative activity) but up-regulated such activity of the committed neural progenitors. A long-term in vivo exposure of mice to ethanol inversed the roles of JAKs and STAT3 in determination of proliferative status of neural stem cells and eliminated involvement of JAKs in functional control over the committed progenitors of neurons. The data attest to much promise of STAT3 inhibitors in treatment of ethanol-induced CNS diseases as the remedies that stimulate realization of growth potential in multipotent neural stem cells and committed neural progenitors.

Abstract
We studied myelotoxicity of modern schemes of chemotherapy for breast cancer (docetaxel/doxorubicin and cyclophosphamide/doxorubicin/5-fluorouracil) towards granulocytopoiesis, the mechanisms determining the differences of hematological effects of these schemes, and the efficiency of correction of the observed changes with granulocyte CSF (filgrastim). Granulocytopoiesis stimulation with filgrastim during the treatment with docetaxel/doxorubicin combination was more pronounced than during cyclophosphamide/doxorubicin/5-fluorouracil therapy. The observed differences were found at all levels of granulocyte lineage organization (central and peripheral), which is related to different effects of the cytostatic substances used in the proposed protocols on the structures controlling hemopoiesis.

Abstract
JAK/STAT signaling pathway was examined during functional stimulation of mesenchymal progenitor cells with fibroblast growth factor. The differences were observed in the realizations of the proliferation-differentiation potential of CFU-fibroblasts under blockade of JAKs or during selective inactivation of STAT3. The study revealed stimulating influences of JAKs and STAT3 on mitotic activity of progenitor cells and individual roles of these proteins in the control of their maturation. Blockade of JAKs diminished the level of fibroblast colony formation and the score of actively proliferating CFU-fibroblasts at the background increase of the differentiation rate of progenitor cells. In contrast, STAT3 inhibitor resulted in a coordinated decrease of all examined parameters.

Abstract
The toxic effects of combined cisplatin/docetaxel therapy cycles on erythroid and granulocytic hematopoietic lineages as well as their intercycle recovery were examined in patients with stage III-IV non-small-cell lung carcinoma. Responsiveness of the blood system to this therapy remained at a high level. Combined therapy pronouncedly activated the key elements of the erythroid and granulocytic hematopoietic lineages leading to accumulation of immature and mature myelokaryocytes in the bone marrow, enlargement of the medullary pool of mature neutrophils, and increase in the count of medullary erythroid and granulocytic precursor cells under conditions of their accelerated maturation.

Abstract
The leading role in the regulation of erythropoietic activity of adherent bone marrow cells under conditions of post-hemorrhagic anemia is played by classical MAP kinase pathway (ERK pathway). Erythropoietin is not the decisive factor in the formation of erythropoietic activity of adherent cells. PI3K, MAPK/ERK 1/2, and p38-signaling proteins are not the main regulators of local production of erythropoietin after 30% loss of circulating blood volume.

The effects of Fructus Sorbi aucupariae extract, originally saturated with anthocyans, on the development of Lewis lung carcinoma and B-16 melanoma in C57Bl/6 mice and the efficiency of cyclophosphamide treatment were studied. Antitumor activity of the extract and potentiation of the antimetastatic activity of the cytostatic were demonstrated. Studies on melanoma B-16 model revealed an increase in the counts of stromal progenitor cells in the tumor node and their accelerated maturation after treatment with the extract. No effects towards the tumor stem and committed cells were detected.

Abstract
Involvement of individual JAK kinases in the realization of growth potential of mesenchymal progenitor cells was examined in vitro. Important role of JAK2 and JAK3 in determining the initial level of mitotic activity of progenitor cells was established. The yield of fibroblast CFUF was suppressed under the effect of specific inhibitors of JAK kinases. Blockade of JAK3 increased the rate of progenitor element differentiation. JAK1 had no effect on proliferation and differentiation status of progenitor cells.

Abstract
We studied the dynamics of erythropoiesis in CBA mice during gestation against the background of treatment with iron-binding drug. The mechanisms of suppression of the bone marrow erythroid stem were evaluated. Administration of deferoxamine in a dose of 1 g/kg induced hypoplasia of the erythroid hemopoietic lineage. Suppression of bone marrow erythropoiesis manifested in a decrease of hemoglobin concentration and counts of reticulocytes, erythrocytes, and erythrokaryocytes. These changes were accompanied by a decrease in functional activity of erythropoietic precursors and secretion of erythropoietically active humoral factors by bone marrow myelokaryocytes. These data indicate that deferoxamine can be used for modeling of iron defi ciency anemia in pregnancy.

Abstract
We studied the role of signaling pathways in the regulation of erythropoiesis against the background of myelosuppression caused by administration of 5-fluorouracil. The important role of cyclic AMP in the maturation of erythroid progenitors after cytostatic treatment was demonstrated. The secretory activity of myelokaryocytes during the period of erythroid hemopoiesis recovery is mainly regulated via the p38 MAPK signaling pathway; non-erythropoietin factors are involved in the formation of erythropoietic activity of adherent cells of the microenvironment.

Abstract
Protein kinase p38 was shown to contribute to the increase in production of granulocyte CSF by microenvironmental cells under conditions of restraint stress. Stimulation of colony-forming activity was not accompanied by the increase in maturation of clonogenic structures in the bone marrow granulocytic stem. This process was realized with the involvement of NF-κB-dependent signaling and p38 MAPK signaling pathway. Our study showed that the p38 MAPK signaling pathway plays an important role in the regulation of granulocytopoiesis, but not of erythropoiesis.

Abstract
We studied the role of cAMP- and IKK-2-dependent pathways under conditions of functional stimulation of mesenchymal progenitor cells by basic fibroblast growth factor. An adenylate cyclase inhibitor 2',5'-dideoxyadenosine had no effect on functional activity of early (primitive) mesenchymal precursors. This agent produced a stimulatory effect on proliferation of stromal precursor cells. Mitotic activity of mesenchymal progenitor cells was shown to decrease after treatment with a specific blocker of the IKK-2 kinase-inhibitor complex.

Abstract
We studied the effect of two pectic polysaccharides PS-B1-AG and PS-B2-RG that were contained in total polysaccharides extracted from Betula pendula leaves on NO production by mouse macrophages and the contribution of signaling molecules to macrophage activation by the test substances. Unlike the total sample, pectins produced a NO-stimulating effect on macrophages. The effect of PS-B2-RG (10 μg/ml) did not differ from the effect of LPS, while PS-B1-AG produced this effect only in a concentration of 20 μg/ml, which was probably due to differences in the chemical structure of the test substances. The studied pectin polysaccharides activated transcription factor NF-κB, kinases p38 and PI3, and cAMP as a negative regulator. These results indicate that Betula pendula polysaccharides are promising substances for creation of immunomodulating drugs.

Abstract
We studied the secretory function of the liver and bone marrow microenvironment cells under conditions of chronic CCl4-induced hepatitis. Enhanced production of substances stimulating parenchymal tissue-specific precursors and stem cell homing factors by liver cells was observed. In situ binding of stem cells by bone marrow elements increased due to production of various cooperation and adhesion factors against the background of reduced SDF-1 secretion.

Abstract
We studied the effect of mobilization of bone marrow multipotent stem cells induced by intragastric administration of pegylated hyaluronate-endo-β-N-acetylhexosaminidase (Peg-HEAHA) on hemopoiesis under conditions of experimental chronic hepatitis. Peg-HEAHA increased the counts of hemopoietic precursors in the hemopoietic tissue against the background of their decelerated maturation. This was paralleled by a short-term decrease in the count of neutrophilic granulocyte in the bone marrow and a slight increase of neutrophil count in the peripheral blood.

Abstract
Pegylated hyaluronate-endo-β-N-acetylhexosaminidase considerably potentiates the hemostimulating effects of erythropoietin due to intensification of proliferation and differentiation of erythroid precursors against the background of enhanced secretion of hemopoietins by nonadherent hemopoiesis-inducing environment cells and elevation of serum erythropoietin concentration. The use of the enzyme allows 10-fold reduction of the maximum effective erythropoietin dose.

Abstract
Regeneratory activities of Baikal aconite alkaloids were studied on the excision skin wound model. Manifest wound healing effects of songorine, napelline, and hypaconitine were detected. The therapeutic efficiency was based on activation of residual mesenchymal progenitor elements. The development of this phenomenon was explained by the direct effects of alkaloids on precursors and by higher production of growth factors by the skin stromal cells. Songorine exhibited the most pronounced specific activity due to more significant stimulation of progenitor cell differentiation associated with maximum activation of the secretory function of the microenvironment cells.

Abstract
The hemostimulatory effects of granulocytic CSF, immobilized on polyethyleneglycol using radiation synthesis nanotechnology, were studied on the model of cyclophosphamide-induced myelosuppression. Immobilization of granulocytic CSF led to stimulation of granulomonocytopoiesis by increasing functional activity of granulomonocytic precursors and secretion of humoral factors by elements of hemopoiesis-inducing microenvironment, and due to more intensive formation of hemopoietic islets. The granulocytopoiesis-stimulating effect of immobilized granulocytic CSF was comparable to the effect of standard nonconjugated granulocytic CSF. Specific activity of immobilized granulocytic CSF in oral treatment was demonstrated.

We compared the stimulatory effects of a preparation of antibodies against erythropoietin in ultralow doses (Poetam) and recombinant erythropoietin (Recormon) on erythropoiesis that was suppressed by carboplatin. Both drugs possessed high erythropoiesis-stimulating activity, which was manifested in an increase in the number of erythrokaryocytes and erythroid precursors in hemopoietic tissue and count of erythrokaryocytes and reticulocytes in the peripheral blood during postcytostatic recovery. Recormon produced a rapid and short-term stimulatory effect on the erythron. The effect of Poetam developed slowly, but persisted for a longer time.

Abstract
We studied reactions of the granulocytic hemopoietic stem during hypoxia of different genesis and severity. Stimulation of granulocytopoiesis was determined by an increase in functional activity of granulomonocytic precursors due to changes in feeder capacity of cells in the hemopoiesis-inducing microenvironment and colony-stimulating activity of the plasma. The development of encephalopathy caused by oxygen deficiency was accompanied by a decrease in the number of bone marrow granulomonocytic precursors due to reduction of proliferative activity (despite the increase in secretory activity of microenvironmental cells and increase in plasma colony-stimulating activity). Severe hypoxia accelerated maturation of hemopoietic cells and produced neutrophilic leukocytosis.

Abstract
The role of regional cerebral neural precursor cells in restoration of the CNS activity during the development of hypoxic encephalopathy and the participation of the bone marrow mesenchymal stem cells in the formation of blood system reactions in hypoxia are shown. The mechanisms of neuroprotective effect of granulocytic colony-stimulating factor in severe oxygen insufficiency are studied. The specific psychopharmacological effect of granulocytic colony-stimulating factor is due to mobilization and determined homing of the bone marrow mesenchymal stem cells in damaged CNS zones with subsequent differentiation of these cells into specialized elements and due to activation of erythropoiesis.

Abstract
The hepatoprotective effects of superlow dose preparation of antibodies to granulocytic CSF were studied on a model of CCl4-induced hepatitis. The preparation exhibited high antiinflammatory and antisclerotic activities determined by stimulation, mobilization, and determined homing of mesenchymal stem cells into damaged liver with subsequent differentiation of these cells into mature hepatocytes.

Abstract
We studied the dynamics of erythropoietin content and erythropoietic activity of the serum during hypoxia of different genesis and severity. Our results show that humoral factors play an important role in the regulation of erythropoiesis during oxygen deficiency. Serum erythropoietic activity underwent similar changes in different types of hypoxia associated with similar hematological shifts. A discrepancy was observed between erythropoietic activity and serum erythropoietin concentration.

Abstract
We studied the role of beta-adrenergic mechanisms of regulation of erythropoiesis in the formation of the erythron system reaction during severe hypoxia. Blockade of beta-adrenoceptors after the incidence of hypoxic encephalopathy of different genesis was followed by an increase in the number of committed precursors in the bone marrow, hyperplasia of the erythroid hemopoietic stem, and rise in the count of peripheral blood erythrocytes. These changes were accompanied by decreased formation of abnormal erythrocytes.

Abstract
We studied changes in the erythroid hemopoietic stem during phenylhydrazine-induced hemolytic anemia. Stimulation of erythropoiesis was associated with increased functional activity of erythroid precursors, which resulted from changes in feeder capacity of hemopoiesis-inducing microenvironmental cells and erythropoietic activity of the plasma. The development of encephalopathy induced by a hemolytic poison was accompanied by a decrease in hyperplasia of bone marrow erythropoiesis. It was related to a decrease in the number of proliferating erythroid precursor cells. These changes accompanied the increase in the secretory function of adherent myelokaryocytes, rise in erythropoietic activity of the plasma, enhanced formation of erythroid hemopoietic islets, and accelerated maturation of hemopoietic cells.

Abstract
We studied the reactions of granulocytic hemopoietic stem after acute hypoxia and during the development of posthypoxic encephalopathy. Damage to brain structures was associated with intensification of the bone marrow hemopoiesis due to activation of hemopoiesis-inducing microenvironment and more intense formation of hemopoietic islets, despite reduced proliferative capacity of granulocytic precursors.

Abstract
Brain pathology (acute hypoxia and posthypoxic encephalopathy) is associated with less pronounced hyperplasia of the bone marrow erythroid stem (due to decreased count of proliferating committed precursors) and hemolytic anemia, while secretory activity of stromal cells of the hemopoiesis-inducing microenvironment is not impaired. Severe oxygen deficiency affects erythroid precursors and impairs production of functionally normal erythrocytes in the posthypoxic period.

Abstract
Pharmacological blockade of dopamine- and serotoninergic structures with haloperidol and cyproheptadine, respectively, attenuated hyperplasia of bone marrow granulocytopoiesis and erythropoiesis (cyproheptadine) caused by conflict situation. At the same time, haloperidol and, especially, cyproheptadine normalized suppressed erythropoiesis and modulated activated granulocytopoiesis under conditions of paradoxical sleep deprivation. These results indicate that central regulation of hemopoietic stems is mediated by different neurotransmitter mechanisms. Erythropoiesis depends on the state of serotoninergic structures, while granulocytopoiesis is regulated both by the dopamine- and serotoninergic systems.
