Resumo

Comparative bioinformatic analysis of sciatic nerve transcriptomes of C57BL/6J mice was carried out. Animals were divided into three groups: Flight, 30-day spaceflight; Recovery, 30-day spaceflight with subsequent 7-day readaptation; and Control. A significant pool of genes with an absolute difference in expression of more than 32 times compared to the control group was revealed in mice after the 30-day spaceflight (Flight and Recovery groups). Comparative analysis of the Flight and Recovery groups of murine transcriptomes did not reveal any significant differences in gene expression. In animals after spaceflight on board the biosatellite, using the KEGG database (Kyoto Encyclopedia of Genes and Genomes), we identified genes related to the state of metabolic and signaling pathways involved in actin cytoskeleton regulation, regulation of potential-dependent calcium, sodium, and potassium channels, and myelination of nerve fibers.
