TGFB1 and rheumatoid arthritis: The expression of LncNFYB was not altered by TNFα and IL-6 but was decreased by TGFβ1 and IL 1β, which indicates that the increased LncNFYB levels in RA-FLS are not because of the different levels of inflammatory stimulation but most likely due to the activation of RA-FLS (Fig. 2G).
