摘要

Hepatocellular carcinoma (HCC) is characterized by poor prognosis and remains a leading cause of cancer mortality worldwide. Advanced HCC is managed with several first-line therapies, including tyrosine kinase inhibitors (TKI) and immunotherapy (mAb-PD-1 and mAb-VEGF). However, the efficacy of HCC therapeutics is often short-lived. Recent studies have demonstrated that the activation of the Nrf2-Bcl-xL pathway contributes to poor prognosis in a subset of HCC patients. Here, we found that dimethyl fumarate (DMF), a drug used for treating psoriasis and multiple sclerosis, regulates the Nrf2-Bcl-xL signaling axis to inhibit HCC growth in a mice xenograft model. Mechanistically, the downregulation of the Nrf2-Bcl-xL axis led to mitochondria stress and apoptosis in vitro and in vivo. Enforced Nrf2 or Bcl-xL expression in HCC cells markedly reversed the antitumor effects of DMF in HCC cells. Importantly, DMF enhanced sorafenib’s antitumor effects. Collectively, our results demonstrate new mechanism insights into the antitumor effects of DMF and that Nrf2-targeted therapy might improve HCC treatment outcomes.
