mRNA Expression of GATA3, FOXP3, TBX21, STAT3, NFKB1, and MAPK8 Transcription Factors in Humans and Their Cooperative Interactions Long-Term after Exposure to Chronic Radiation.

The results of mRNA expression of the GATA3, FOXP3, TBX21, STAT3, NFKB1, and MAPK8 transcription factors in peripheral blood cells of 264 residents of the Techa riverside villages of the Chelyabinsk and Kurgan regions, who were affected by chronic low dose-rate exposure in the 1950s, are shown. The range of individual doses to the red bone marrow due to external gamma exposure and 90Sr was 77.8–3507.1 mGy, and the mean dose was 706.3±46.3 mGy. It has been found that changes in the transcriptional response of the cell occur at the molecular level in the long term after chronic exposure. A modified expression of the immunoregulatory genes NFKB1 and MAPK8 in the peripheral blood cells of exposed people was found. A comparative analysis of the interaction of the studied mRNAs demonstrated the presence of a link between the MAPK8 and NFKB1 genes in the group of chronically exposed individuals. The results obtained may indicate the involvement of these transcription factors in the impairment of the immune response in the exposed population. [ABSTRACT FROM AUTHOR]
