Cyclin D1 Overexpression Detected by a Simple Competitive Reverse Transcription‐polymerase Chain Reaction Assay for Lymphoid Malignancies
t(11;14)(q13;q32) observed in B‐cell malignancies is associated with cyclin D1 (bcl‐1, PRAD1, CCND1) overexpression. We devised a simple competitive reverse transcription‐polymerase chain reaction (RT‐PCR) assay for rapid detection of cyclin D1 overexpression. Sharing a single upstream primer derive...

description | t(11;14)(q13;q32) observed in B‐cell malignancies is associated with cyclin D1 (bcl‐1, PRAD1, CCND1) overexpression. We devised a simple competitive reverse transcription‐polymerase chain reaction (RT‐PCR) assay for rapid detection of cyclin D1 overexpression. Sharing a single upstream primer derived from a homologous sequence in cyclins D1, D2 and D3, each PCR product serves as a competitor and cyclin D1 overexpression is determined by comparing the intensities of the three amplified products. We analyzed cyclin D1 in clinical specimens from 104 patients with lymphoid malignancies. Cyclin D1 overexpression was evident in 13 of 104 (7/72 non‐Hodgkin's lymphomas, 0/6 adult T‐cell lymphoma/leukemias, 0/4 Hodgkin's diseases, 0/11 acute lymphoblastic leukemias, 3/4 multiple myelomas, 1/2 Waldenströmas, macroglobulinemias, 1/2 prolymphocytic leukemias and 1/3 chronic lymphocytic leukemias). Among 72 patients for whom cytogenetic studies had been done, all 7 patients with t(11;14) were positive. The relative expression levels of D‐type cyclins altered dramatically in the presence of t(11;14). Thus, this RT‐PCR assay can identify tumors with cyclin D1 overexpression. Cyclin D1 overexpression was frequent in extranodal specimens (11 out of 32 vs. 2 of 72 lymph nodes) and was restricted to specific types of lymphoid malignancies, as observed using other methods. This reliable assay should be suitable to provide clinical guidance for the diagnosis and management of lymphoid malignancies, especially in the case of extranodal involvement. |
