Targeting NUPR1 with the Small Compound ZZW-115 Is an Efficient Strategy to Treat Hepatocellular Carcinoma

International audience; HCC is a highly lethal malignancy with Sorafenib as the only molecularly targeted drug. The multifunctional stress-associated protein, NUPR1, plays an essential role in controlling cell growth, migration, invasion and Sorafenib resistance in HCC. We report here that NUPR1 expression is absent in healthy liver and it is progressively upregulated in HCC premalignant lesions such as hepatitis and cirrhosis with a maximum expression in HCC samples, highlighting that NUPR1 is a potential drug target for HCC. We therefore assessed in this work, ZZW-115, a strong inhibitor of NUPR1, as a promising candidate for the treatment of HCC. We validated its extraordinary antitumor …
