CD221 (IGF-1R) is aberrantly expressed in multiple myeloma, in relation to disease severity

Haematologica. 2005 May;90(5):706-7.

Abstract

We investigated the expression of insulin-like growth factor-1 receptor (CD221) in normal, reactive and malignant plasma cells. We show that CD221 is aberrantly expressed on human myeloma cells, that higher levels of CD221 are observed in patients and human myeloma cell lines with the most aggressive 14q32 translocations, and that CD221 expression has a negative prognostic impact in patients with multiple myeloma.
