ZFP36L2 and cystic fibrosis: We found a significant increase in gene expression levels of AOC3, PDF1. 2 and ERF2 at 1 and 2 dpi in RRCC, suggesting that both genotypes quickly respond to TH12 and its CF, but the levels of PR-1, TGA5 and TGA6 genes did not increase in either genotype treated with TH12 compared with those treated with CF.
