doi: 10.1126/sciadv.aec4368

Figure Lengend Snippet: ( A ) Liver tumor tissues were collected from the HTVi model and clinical patients and subjected to untargeted metabolomic profiling for pathway enrichment. ( B ) Summarized SLC transporters for TCA cycle intermediates. ( C ) Forest plot showing the hazard ratios (HR) for multiple genes encoding SLC transporters of TCA cycle intermediates in HCC. The horizontal line represents the 95% confidence interval. ( D ) Heatmap of detectable SLC transporters for TCA cycle intermediates in heterogeneous primary liver cancer models generated by genome editing of cancer driver genes selected by mutational frequency from human HCC cohorts (PRJNA674008). ( E ) qPCR analysis to screen candidate SLC transporters for HCC progression based on the relative expression of SLC transporters in the HTVi model ( n = 4 for the control group and n = 5 for the model group), mouse HCC Hepa1-6 cells, AML12 cells, and MPHs ( n = 3 independent experiments). ( F ) Venn diagram showing the overlap of significantly differentially expressed SLC transporters in the HTVi model, mouse HCC Hepa1-6 cells, and normal hepatocytes (AML12 and MPHs). ( G and H ) SLC13A2 expression in liver tissues from HTVi, AAV-cMYC/nRAS, and STZ-HFD HCC model. The data are presented as means ± SEM. * P < 0.05; ** P < 0.01, two-tailed unpaired Student’s t test. Ctrl, control; n.d., not determined; NS, not significant.

Article Snippet: The mouse HCC cell line Hepa1-6 and mouse normal hepatocyte cell line AML12 were obtained from the American Type Culture Collection as described previously ( ).

Article Title: TM4SF5-mediated KEAP1 Regulation in Hepatocytes Irrelevant to NRF2 Expression and Activity Promotes Oxidative Stress and Inflammation to Develop Metabolic Dysfunction-Associated Steatotic Liver Disease

doi: 10.7150/ijbs.126251

Figure Lengend Snippet: TM4SF5-mediated stabilization of KEAP1 in lipid-treated hepatocytes promotes oxidative stress and hepatic inflammation. (A-F) Subconfluent Huh7 Control or Huh7 TM4SF5-KO hepatocyte variants, either stably or transiently transfected with the indicated cDNAs, were analyzed for ROS production using flow cytometry following DCFDA staining. Cells received vehicle treatment (-), PA alone (B, D, and F), lipid mixture (LM, C), or DOX to induce Keap1 knockdown (shKEAP1 #2 or #3 , see Table , C and D). In some experiments, Huh7 cell variants were transfected with siNS (non-specific sequences as a control) or siNRF2 (targeting sequence #1 or #2, see Table ) for 24 h. Cells were then treated with DOX for shKEAP1 #2 induction for 24 h, followed by PA for 4 h prior to ROS analysis by flow cytometry (D). Cells were also exposed to H 2 O 2 at the indicated concentrations and durations before assessment of ROS levels (E). *, P < 0.05; **, P < 0.01; ***, P < 0.001; ***, P < 0.0001; ns = non-significant, unpaired Student's t test or two-way ANOVA. Data are expressed as mean ± SEM. (G) Subconfluent SNU449 hepatocytes stably expressing empty vector (SNU449 EV ) or TM4SF5 (SNU449 TM4SF5 ) were harvested to perform qRT-PCR for the indicated molecules. (H) Subconfluent Huh7 Control cells were treated in the absence (-) or presence (+) of DOX to induce KEAP1 knockdown (shKEAP1 #2 ) for 24 h and then exposed to PA (100 μM) for 4 h before being collected for immunoblot analysis of the indicated molecules. (I) Murine AML12 cells stably transfected with EV or TM4SF5 were treated with 5% LM for 24 h, harvested, and subjected to qRT-PCR for the indicated molecules. Data shown are representative of three independent experiments. See also .

Article Title: Echinacoside as a Novel Ferroptosis Inducer in Hepatocellular Carcinoma: Mechanistic Insights from TP53/SLC7A11/GPX4 Pathway Modulation

doi: 10.3390/ijms27010411

Figure Lengend Snippet: The results of HCC cell growth inhibited by ECH. ( A ) HepG2 cells were treated with different concentrations of ECH for 24 h. ( B ) Huh7 cells were treated with different concentrations of ECH for 24 h. ( C ) LO2 cells were treated with different concentrations of ECH for 24 h. Abbreviations: ECH: echinacoside. HCC: hepatocellular carcinoma. IC 50 : half-maximal inhibitory concentration.
