Fig. 2From: Dynamic assessing silica particle-induced pulmonary fibrosis and associated regulation of long non-coding RNA expression in Wistar ratsBar graph of the number of differentially expressed mRNAs at five times points. The abscissa represents the different time points (day 1, 7, 14, 21, 28 after treatment). The ordinate represents the number of differentially expressed mRNAsBack to article page
