For example, FAPB4, also known as (adipocyte) fatty acid binding protein 4, was recently found to be upregulated in LSECs during liver fibrosis, can promote LSEC capillarization and is suggested to be a key regulator involved in the onset and progression of fibrosis in two liver fibrosis models in mice (58). The gene discussed is FABP4; the disease is Hepatic fibrosis.
