Transcription profiling of mouse B cells from wild type or mir-155 deficient mice, treated with a-mir155 PNA


ABSTRACT: B cells were extracted from spleens of mice treated with PNA a-miR155 and vehicle treated mice either wild type or mir-155 deficient. All mice received LPS to induce mir155 expression.

MicroRNAs (miRNAs) play an important role in diverse physiological processes and are potential therapeutic agents. Synthetic oligonucleotides (ONs) of different chemistries have proven successful for blocking miRNA expression. However, their specificity and efficiency have not been fully evaluated. Here, we show that peptide nucleic acids (PNAs) efficiently block a key inducible miRNA expressed in the haematopoietic system, miR-155, in cultured B cells as well as in mice. Remarkably, miR-155 inh  ...[more]
