Figure 2D,F,L indicate a tendency of a non-significant upregulation of NFKB2, NFKB3, NFKBIB genes under simulated microgravity (s-μg) in AD cells and especially in MCS, while Fig. 2A,I,M,N show a significant upregulation of NFKB1, NFKBIA, NFKBIE and NFKBG genes in MCS cells as compared to control cells. This evidence concerns the gene NFKB1 and Alzheimer disease.
