To determine the expression of inflammatory microRNAs, macrophages from C57BL/6 WT mice were treated with PTEN siRNA or scrambled siRNA as above. RNA was then extracted from the cells using Qiagen RNeasy mini kit according to the manufacturer’s instructions. cDNA was synthesized using the RT2 microRNA First Strand Kit (Qiagen) and applied to PCR focused immunopathology microRNA array plates (Qiagen) as previously shown (10 (link)). Normalization and statistical analysis of miRNA expression was conducted using SABiosciences’ Online PCR Array Data Analysis Web Portal as previously described (10 (link)).
