Recently, a new synthetic copolymer [99mTc]p(VLA-co-VNI) was (Figure 5C) reported by Zhang et al and imaging studies of [99mTc]p(VLA-co-VNI) can identify different stages of liver fibrosis, which is CCl4-induced liver fibrosis in mouse models.41 The authors first demonstrated ASGPR expression correlated with liver fibrosis progression. The gene discussed is ASGR1; the disease is Hepatic fibrosis.
