SPIOCA regulates microbiota-derived sphingolipid metabolism. (a–c) Pathway enrichment analysis of the significantly changed metabolites in colonic contents, serum and brain tissues. (d) Graphical representation of sphingolipid metabolism. (e) Immunofluorescence of the expression of S1PR2 in the mouse cochlea (n = 3). Scale bars: 20 μm. (f) Quantification of S1PR2 expression in the cochlea. OC, organ of Corti; SGN, spiral ganglion neuron. (g) Immunofluorescence of S1PR2 expression in cochlear hair cells. Hair cells were stained for myosin 7a (n = 3). Scale bars: 20 μm. (h) Quantification of S1PR2 expression in the hair cells. *P < 0.05; **P < 0.01; ****P < 0.0001.
