Ing4 mRNA expression levels in BLM-induced pulmonary fibrosis. Ing4 gene expression levels quantified by qRT-PCR showed a trend to increase, compared to control untreated mice, at early disease stages (day 7 post-administration) whereas a gradual decline, compared to control and day 7 mice, following disease progression (days 7 and 15) was easily noted. All values were normalized with the reference gene B2m and presented as relative expression to the control sample as described in materials and methods. *p < 0.05, **p < 0.005, ***p < 0.001. (One way ANOVA).
