The traces show metabolic responses to sequential injections (indicated by dashed lines) of glucose (20 mM), oligomycin (1.5 µM), FCCP (0.5 µM), and finally rotenone/antimycin A (0.5 µM). (D, I) Glucose-stimulated insulin secretion (GSIS) stimulation index (SI) for (D) primary and (I) SC-islets, calculated as the ratio of high-to-low glucose secretion. (E, J) Extracellular acidification rate (ECAR) of (E) primary and (J) SC-islets, measured concurrently with OCR. *Data in (B, D, G, I) are presented as mean ± SEM of n=3 (primary) or n=4 (SC-islets) biological replicates; individual data points are shown as open circles. Data in (B, E, G, J) are representative traces from a single experiment, with lines showing the mean ± SEM of technical replicates. For insulin secretion (B, G) and stimulation index (D, I), statistical significance was assessed using repeated measures ANOVA followed by pairwise t-tests with Bonferroni correction for post-hoc analysis. Significance is denoted as *p < 0.05, **p < 0.01.

    A) Schematic representation of the FASN CRISPR/Cas9 KO (FASN KO) in HCT116 cells.
