Defective RNA-mediated c-myc gene silencing pathway in Burkitt's lymphoma.
Keeping in view the fact that molecular basis of Burkitt's lymphoma (BL) is poorly understood, we attempted to explore the small interfering RNA (siRNA) mediated c-myc gene regulation using BL-derived EB-3 cell line as archetype cellular model. Such a study revealed that EB-3 cells possess 4-fold higher expression of Dicer gene coupled with 2-fold higher activity of RNA polymerase III than that observed in normal human lymphocytes. siRNAs derived from EB-3 cells had the inherent capacity to suppress c-myc gene expression in normal cells but not in native cells. Based on these findings we have proposed a novel RNA-mediated c-myc gene regulation pathway that may be responsible for BL.[1]References
