Abstract:
:Chromosomal analysis of three human non-Hodgkin's lymphoma (NHL) xenografts revealed common extra 14q+ segment and other individual clonal markers without involvement of immunoglobulin light-chain regions. Two NHL xenografts (HT 58 and HT 130) showed restricted lambda light chain expression and deleted kappa and rearranged lambda genes. However, in HT 117 both kappa and lambda chains were present on the cell surface, and both light chain genes showed rearranged alleles. This unique phenomenon could have resulted from either disturbed regulation of isotype exclusion or from the malignant transformation of light chain 'uncommitted' B cells.
