Fig. 2From: Comprehensive gene expression profiling identifies distinct and overlapping transcriptional profiles in non-specific interstitial pneumonia and idiopathic pulmonary fibrosisGene expression levels determined by oligonucleotide microarray in the IPF (blue), NSIP (green) and normal control (red) groups. Examples of genes upregulated in both IPF and NSIP: a. Matrix Metalloproteinase 7 (MMP-7). b Osteopontin (also known as Secreted Phosphoprotein 1). Examples of genes specifically upregulated in IPF: c Insulin Growth Factor Binding Protein 5 (IGFBP-5). d Smooth muscle alpha-2 actin (ACTA-2). Examples of genes upregulated in both NSIP and normal controls: e Long Pentraxin 3 (PTX-3). f Indoleamine 2–3-dioxygenase-1 (IDO-1). Examples of genes specifically upregulated in NSIP: g Interferon-induced protein 44-like (IFI-44). H. LDL receptor related protein 2 (LRP-2)Back to article page
