We determined the DNA sequence of two large regions of chromosome 22: 33.7 kb containing the C lambda complex; and 5.2 kb 5' of the functionally rearranged lambda gene from the human myeloma, U266. Analysis of these sequences reveals the complete structure of the human C lambda complex and a previously undescribed seventh C lambda region that may encode the Ke+Oz- lambda protein. The seven cons...

Previous studies show that human myeloma-derived cell lines specifically adhere to fibronectin (FN) through very late antigen-4 (VLA-4; alpha 4 beta 1 integrin complex) and RGD-peptide mechanisms, which may contribute to the localization of tumor cells in bone marrow (BM). In these studies, we characterized the adhesion of myeloma-derived cell lines to both normal and myeloma BM stromal cells (...

Currently considered incurable, multiple myeloma (MM) is characterized by proliferation of malignant plasma cells (PC) predominantly in the bone marrow, which overproduce monoclonal immunoglobulin proteins, and a perturbed tumor microenvironment, which promotes PC survival, inhibits osteoblast activity, increases osteoclast activity, and leads to hallmark osteolytic bone disease, all of which c...

Background Despite improvements with new therapeutics, multiple myeloma (MM) patients still relapse and become refractory. Myxoma virus (MYXV) selectively replicates in human tumor cells stimulates the immune system. MYXV kills patient MM spares normal progenitors. also eradicates growth of a disseminated mouse vivo. is large, double stranded DNA poxvirus, has genome size amenable to insertion ...
