Fig 4. ACSL1 protein abundance and membrane localization increase under inflammatory conditions.

BMDMs were differentiated under NG conditions. A) Total cell lysates were prepared with (+) and without (-) LPS treatment (10 ng/ml for 24 hours). ACSL1 protein expression was determined by western blot with an anti-ACSL1 antibody. An anti-alpha tubulin antibody was used as a loading control. B) Bands were quantified using the Image studio 5.2. C) Cytoplasmic and membrane proteins were isolated to determine the localization of ACSL1 protein by western blotting as a function of LPS treatment. Alpha-tubulin (cytoplasmic protein) and Na+/K+ ATPase (membrane-associated protein) were used to confirm the fidelity of fractionation. D) Images were quantitated as in B with cytoplasmic ACSL1 protein normalized to tubulin and membrane ACSL1 protein normalized to Na+/K+ ATPase. The data presented are means ± standard error (n = 3); the p-value was calculated using student’s t-test. (*p < 0.05). E) Mitochondria were isolated from BMDMs, and ACSL1 abundance was determined by western blot with and without LPS treatment. The non-specific (ns) band serves as a loading control.
