CTSB and Hepatic fibrosis: Interestingly, lysosomal proteins such as cathepsin B (CTSB), lysosomal acid lipase (LIPA), dipeptidyl peptidase 2 (DPP), and glycosylated lysosomal membrane protein (GLMP), which are known to be involved in liver fibrosis, liver damage, and steatosis, were found to be differentially expressed.
