Both twin comparisons to CTRL group shared the first four pathways, which together with Wound Healing Signaling Pathway and Pulmonary Fibrosis Idiopathic Signaling Pathway contained Hepatic Fibrosis/Hepatic Stellate Cell Activation (−log10(p value) = 11.5 in ST vs. CTRL and 10.9 in HT vs. CTRL) and GP6 Signaling Pathway (−log10(p value) = 5.1 in ST vs. CTRL and 4.5 in HT vs. CTRL). This evidence concerns the gene GP6 and Hepatic fibrosis.
