Dasatinib treatment had no significant effect on gene expression levels in cultured LN fibroblasts, although dasatinib restored the expression levels of TP53, CDKN2A, CDKN1A, and FOXO4 in RA(-risk) LN fibroblasts to the expression levels measured in control LN fibroblasts and partially restored the expression levels of IL6, NOTCH3, LMNB1, and CD38. This evidence concerns the gene CDKN1A and rheumatoid arthritis.
