Treatment of HCC cells with ADI-PEG20 downregulates the key enzymes of pyrimidine synthesis in the TCA cycle, carbamoyl phosphate synthetase 2, thymine synthase (TS), aspartate transcarbamylase and dihydrooratase (CAD) and malate dehydrogenase 1 (MDH-1) activities, making tumor cells more susceptible to 5-fluorouracil (5-FU)

In this article, the authors showed that uPAR is expressed in senescence cells, both in in vivo and in vitro models (liver fibrosis, pancreatic intraepithelial neoplasia, senescent melanocytes, or lung cancer) correlated to a lack of expression in healthy tissue, except for the bronchial epithelium and a subset of immune cells in which a weak expression of uPAR was detected
