Allergen exposure enhanced miR-125b expression and autophagy by upregulating CXCR4. A. qPCR measurement of CXCR4 in cells treated with PBS, Derp1, or both Derp1 and AMD3100. B. Western blot analysis of CXCR4 and p-CXCR4 in cells treated with PBS, Derp1, or both Derp1 and AMD3100. C. GFP-LC3 cells treated with PBS, Derp1, or both Derp1 and AMD3100, LC3 expression was tested by fluorescence microscope. D. qPCR measurement of miR-125b in cells treated with PBS, Derp1, or both Derp1 and AMD3100. Data were shown as mean ± SD from three independent experiments. *P < 0.05, **P < 0.01.
