MALAT1 and infection: Considering the differences observed in the expression profile of the analyzed lncRNAs in B. abortus-infected RAW264.7 macrophages at 8 and 24 h post-infection, we examined the expression levels of lincRNA-Cox2, Lethe, lincRNA-EPS, GAS5, and Malat1 by RT-qPCR after 1, 6, and 12 h post-infection.
