Article Title: ZFAS1/STAT3 axis modulates imatinib resistance of chronic myeloid leukemia cells through glucose metabolism reprogramming
doi: 10.3389/fonc.2025.1603060
Figure Lengend Snippet: STAT3 overexpression reverses the effects of ZFAS1 knockdown on imatinib sensitivity and glucose metabolism reprogramming in IM-resistant K562 cells, including si-NC+NC, si-ZFAS1+NC, and si-ZFAS1+STAT3 IM-R K562 cells. (A) Drug sensitivity assay by CCK-8 showing relative cell viability of cells treated with varying concentrations of IM. (B) IC50 values were determined via CCK-8 assay after 48 hours of imatinib treatment. (C) Relative glucose uptake levels. (D) Relative lactate production. (E) Relative ATP levels. (F) ECAR over time. (G) Glycolysis and glycolytic capacity. (H) OCR over time. (I) Summary of basal respiration and maximal respiration. ** p <0.01, *** p <0.001 vs . si-NC+NC; # p <0.05, ## p <0.01, ### p <0.001 vs . si-ZFAS1+NC.
Article Snippet: Human leukemic cell line K562 cells were procured from ATCC in Manassas, VA, USA, and maintained in RMPI 1640 medium supplemented with 10% heat-inactivated FBS, 100 U/ml penicillin, and 100 μg/ml streptomycin.
