A The mRNA expression of (a1) STEAP4 (a2) CCL2 (a3) TNF and (a4) IL1B after 72 hours exposure of RAW 264.7 cells to either 8/16 hours repetitive cycles of mannitol osmolar fluctuations (control group) glucose fluctuations or 0.1mM of 4-octyl itaconate at every peak of glucose fluctuation (RT-qPCR) Data expressed as a fold change normalized to GAPDH Values are Means ± SEM (n = 5–5–5) **p < 0.01 ***p < 0.001 against the mannitol osmolarity-control group O.I* stands for 4-octyl itaconate. B The mRNA expression of (b1) STEAP4 (b2) CCL2 (b3) TNF and (b4) IL1B after 24 hours exposure of RAW 264.7 cells to either a vehicle control (BSA) a combination of 100μM palmitic acid and 100nM Insulin or a combination of 100μM palmitic acid and 100nM Insulin and 0.1mM of 4-octyl itaconate (RTqPCR)Data expressed as a fold change normalized to GAPDH Values are Means ± SEM (n = 5–5–5) **p < 0.001 against the vehicle-control group O.I* stands for 4-octyl itaconate. C The effect of (c1) PDTC an inhibitor of NF-κB activation on glucose spikes-induced STEAP4 mRNA expression in RAW 264.7 cells (c2) SB203580 a p38 MAPK inhibitor on glucose spikes-inducedSTEAP4 mRNA expression in RAW 264.7 cells (c3) PDTC an inhibitor of NF-κB activation on persistent high-glucose induced STEAP4 mRNA expression in RAW 264.7 cells (c4) SB203580 a p38 MAPK inhibitor on persistent high-glucose induced STEAP4 mRNA expression in RAW 264.7 cells Dataexpressed as a fold change normalized to GAPDH Values are Means ± SEM (n = 5–5–5) ***p < 0.001 **p < 0.01 *p < 0.05 NS means not statistically significant. D The effect of (d1) PDTC an inhibitor of NF-κB activation on palmitic acid-high insulin-induced STEAP4 mRNA expression in RAW 264.7 cells (d2) SB203580 a p38 MAPK inhibitor on palmitic acid high insulin-induced STEAP4 mRNA expression in RAW 264.7 cells Data expressed as a fold change normalized to GAPDH Values are Means ± SEM (n = 5–5–5) ***p < 0.001 **p < 0.01
