STTT:清华大学董家鸿院士团队发现肝癌治疗新靶点,逆转肝癌耐药性
生物世界· 2025-08-04 08:00
Core Viewpoint - The study identifies AKR1B1 as a key regulatory enzyme in metabolic reprogramming and a potential biomarker and therapeutic target for hepatocellular carcinoma (HCC), suggesting that targeting AKR1B1 can reverse systemic therapy resistance in HCC [3][7]. Group 1: Research Findings - HCC is a major subtype of liver cancer and a leading cause of cancer-related deaths globally, with high incidence and mortality rates [2]. - The research team established HCC cell lines with multidrug resistance characteristics, observing enhanced metabolic activity in these cells [5]. - Multi-omics analysis revealed that glucose-lipid and glutathione metabolic pathways are overactive, playing critical roles in supporting tumor cell proliferation and survival [5]. Group 2: Mechanism of Resistance - The study constructed a metabolic reprogramming map for resistant HCC cells, identifying AKR1B1 as a key regulatory factor that maintains resistance by modulating energy metabolism and enhancing stress tolerance [5]. - The expression level of AKR1B1 is closely related to drug resistance and poor prognosis in HCC patients, highlighting its predictive value [5]. Group 3: Therapeutic Implications - The combination of Epalrestat, a clinically approved AKR1B1 inhibitor, with standard therapy (Lenvatinib) significantly alleviated resistance in HCC [7]. - The findings provide new insights into the mechanisms of resistance in HCC and lay the theoretical foundation for developing new predictive biomarkers and therapeutic strategies to overcome resistance [7].
