Role of NF-κB-dependent signaling and p38 MAPK signaling pathway in the control of hemopoiesis during cytostatic administration.

The study examines the role of signal pathways in triggering the compensatory reactions in the blood system in response to the cytostatic administration. In vitro experiments elucidated the involvement of protein kinase p38 in the synthesis of granulocytic CSF by cells of hemopoietic microenvironment. The important role of the transcriptional factor NF-κB and protein kinase p38 in limitation of the processes of maturation of the hemopoietic precursors was demonstrated.
