Core Viewpoint - The study reveals that RIOK1 phase separation restricts PTEN translation via stress granules, promoting tumor growth in hepatocellular carcinoma (HCC) [4][12]. Group 1: Mechanism of Drug Resistance - RIOK1 phase separation mediates the formation of stress granules under TKI treatment stress, recruiting IGF2BP1 and G3BP1 to form dynamic stress granules [11]. - Stress granules selectively encapsulate PTEN mRNA, inhibiting its translation into PTEN protein, leading to the inactivation of the PTEN/PI3K/AKT pathway [11]. - The loss of PTEN activates the pentose phosphate pathway (PPP), increasing NADPH production and antioxidant capacity, helping cancer cells eliminate TKI-induced reactive oxygen species (ROS) [11].
