Title miR-28 expression in the Burkitt lymphoma cell line P3HR1
Organism Homo sapiens
Experiment type Expression profiling by array
Summary Burkitt lymphoma (BL) is a highly aggressive B cell non-Hodgkin lymphoma (B-NHL), which originates from germinal center (GC) B cells and harbors translocations deregulating the MYC oncogene. A comparative analysis of microRNAs (miRNAs) expressed in normal and malignant GC B cells identified miR-28 as significantly down-regulated in BL, as well as in other GC-derived B-NHL. We show that re-expression of miR-28 impairs cell growth and clonogenic properties of BL cells by modulating several targets including MAD2L1, a component of the spindle checkpoint whose down-regulation is essential in mediating miR-28-induced growth-arrest, and BAG1, an activator of the ERK pathway.
Overall design P3HR1 Burkitt lymphoma cell line was engineered to display inducible expression of GFP alone or GFP in combination with the miR-28 precursor from the pRTS1 vector upon doxycycline treatment. Two bulk populations (A and B) were established for both the control (GFP alone) and the miR28-expressing (GFP and miR-28 precursor) cells. Cells were induced with 0.1ug/ml doxycycline for 12h or 24h. Induction was performed on each bulk population in triplicates.
