Expression of ZFP36 and ZFP36L1 after scratch-wounding at the RNA and at the protein level. qPCR and Western blot analysis were performed on RNA and proteinsamples derived from quiescent, scratch-wounded keratinocyte monolayers as indicated. The blots were also probed with an antibody directed against GAPDH as a loadingcontrol and a reference for normalization. Data are expressed as means +/− SD (n = 5). *: p < 0.05; **: p < 0.01.
