CCN2 and Hepatic fibrosis: Phycocyanin is one of the major phycobiliproteins in Arthrospira; it inhibits the levels of epithelial mesenchymal transition (EMT) [19], connective tissue growth factor (CTGF), and α-smooth muscle actins (α-SMA) [20], which play central roles and are clinically relevant in HBV-induced hepatic fibrosis [21,22,23].
