摘要: We have analyzed immunoglobulin light chain sequences from avian leukosis virus (ALV) induced bursal and metastatic tumors cell lines derived these tumors. Sequence data presented demonstrate that ALV-induced one line (DT40) therefrom continue to diversify their genes outside of the environment. Diversification within tumor cells seems occur by gene conversion events comparable with those observed in B cells. analysis spontaneously arising surface negative subclones DT40 revealed frameshifts rearranged which most likely resulted non-functional recombination events. Superimposed can repair leading re-expression immunoglobulin.
