The results from TB lung transcriptional profiling (Supplementary Data 2), combined with previous studies30, suggested that multiple members of MMPs, including MMP1, MMP2, MMP3, MMP7, MMP8, MMP9, MMP10, MMP11, MMP12, MMP13, and MMP14, were potentially involved in TB-induced lung remodeling. The gene discussed is MMP12; the disease is tuberculosis.
