When calculating the half-lives of endogenous mRNAs in glioblastoma cells transfected with p48, we found that DRA mRNA (t1/2=3.54 h; Fig. 8A) was more stable than the DRA messenger from cells transfected with p42 or empty vector (t1/2=2,45 h; Fig. 8A). This evidence concerns the gene SLC26A3 and glioblastoma.
