We found an association between <i>LIG4</i>-rs1555902 and decreased MM risk, which approached statistical significance, as well as significant associations between <i>AICDA-</i>rs3794318 and better outcome.
Moreover, interleukin-6 exposure to KMS12PE led to upregulation of BCL6 and AID, downregulation of ATM, and attenuation of DDR, which were consistent with the effects of BCL6 overexpression in this MM cell line.
Here, we show that interaction between myeloma and DCs, but not monocytes, leads to rapid induction of the genomic mutator activation-induced cytidine deaminase (AID) and AID-dependent DNA double-strand breaks (DSBs) in myeloma cell lines as well as primary MM cells.
Using 2 specific antibodies, here we show that the AID protein can be detected in GC centroblasts and their transformed counterpart (Burkitt lymphoma) but not in pre-GC B cells and post-GC neoplasms, including B-cell chronic lymphocytic leukemia and multiple myeloma.
In a survey of human B-NHL AID was found to be constitutively expressed in follicular lymphoma and in diffuse large B-cell lymphoma but to be absent in B-precursor lymphoblastic leukemia, in mantle cell lymphoma, and in plasma cell myeloma.
A chromosomal translocation (Tx) that interrupts the transcription of either c-Myc or Pvt 1 is the principal lesion in many B cell malignancies including Burkitt's Lymphoma (BL), AIDs-NHL, mouse plasmacytoma (Pct) and possibly multiple myeloma (MM).
