Project description:AID (activation-induced cytidine deaminase) is expressed at low levels in many tissue types but is most highly expressed in germinal center B cells where it deaminates cytidine to uracil during somatic hypermutation and class switch recombination of the immunoglobulin genes. In addition to this critical role in immune diversification, aberrant targeting of AID contributes to oncogenic point mutations and chromosome translocations associated with B cell malignancies. Thus, to explore a role for AID in DNA demethylation in B cell lymphoma, we performed genome-wide methylation profiling in BL2 and AID-deficient (AID-/-) BL2 cell lines (Burkitt lymphoma that can be induced to express high levels of AID).

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
