Small RNA profiling of RNase III enzyme deficient DN3 thymocytes, Tregs, activated CD4+ T cells, and embryonic fibroblasts

Here we analyze the small RNA species in the following: 1. DN3 thymocytes following inactivation of LoxP flanked Drosha and Dicer alleles with Lck-cre 2. Tregs following inactivation of LoxP flanked Drosha and Dicer alleles with CD4-cre 3. activated CD4+ T cells following inactivation of LoxP flanked Drosha and Dicer alleles with CD4-cre 4. MEFs following inactivation of LoxP flanked Drosha and Dicer alleles with Rosa26-CreER and 4-OH tamoxifen treatment Fractionation of small RNAs (19-30nt) and cloning of only RNA with 5' phosphates and 3' hydroxyls
