CDKN1A and fibrosis: When the gene expression was determined in fibrosis patients (n = 41) compared to the control group (n = 32), a slight trend towards upregulation in VEGFA (fold change = 1.56, p = 0.0617), CXCL8 (fold change = 1.65, p = 0.1009), and CDKN1A (fold change = 2.13, p = 0.0148) was observed, without being statistically significant with the exception of the CDKN1A gene.
