[Q]: Question: Does overexpression of microRNA-155 suppress chemokine expression induced by Interleukin-13 in BEAS-2B human bronchial epithelial cells?
Answer: miR-155 specifically inhibits IL-13-induced expression of eosinophilic chemokines CCL11 and CCL26 in bronchial epithelial cells, even though the 3'-untranslated region of these genes do not contain a consensus binding site for miR-155.
