Fig. 7: Knockdown of SLC15A3 did not affect the proximal cytoplasmic signaling.

a, b Protein expression of p-p38, p38, p-p65, p65, SLC15A3 and GAPDH in THP-1 cells transfected with 30 nM control siRNA or SLC15A3 siRNA. Twenty-four hours after transfection, the cells were treated with 100 ng/mL LPS for the specified period of time. c Protein expression of p65, histone H3 and GAPDH in THP-1 cells transfected with 30 nM control siRNA or SLC15A3 siRNA. Twenty-four hours after transfection, the cells were treated with 100 ng/mL LPS for 30 min, and then separated into cytoplasmic and nuclear fractions for the determination of p65 protein expression. The purity of cytoplasmic and nuclear fractions was confirmed by cytoplasmic (GAPDH) and nuclear (histone H3) markers
